Copyright (C) 2004-2015 Free Software Foundation, Inc. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled "GNU Free Documentation License". 1 Brief Overview **************** Gnulib is a source code library that provides basic functionality to programs and libraries. Many software packages make use of Gnulib to avoid reinventing the portability wheel. Resources: * Gnulib is hosted at Savannah: . Get the sources through Git from there. * The Gnulib home page: . 1.1 Gnulib Basics ================= While portability across operating systems is not one of GNU's primary goals, it has helped introduce many people to the GNU system, and is worthwhile when it can be achieved at a low cost. This collection helps lower that cost. Gnulib is intended to be the canonical source for most of the important "portability" and/or common files for GNU projects. These are files intended to be shared at the source level; Gnulib is not a typical library meant to be installed and linked against. Thus, unlike most projects, Gnulib does not normally generate a source tarball distribution; instead, developers grab modules directly from the source repository. The easiest, and recommended, way to do this is to use the 'gnulib-tool' script. Since there is no installation procedure for Gnulib, 'gnulib-tool' needs to be run directly in the directory that contains the Gnulib source code. You can do this either by specifying the absolute filename of 'gnulib-tool', or by using a symbolic link from a place inside your 'PATH' to the 'gnulib-tool' file of your preferred Gnulib checkout. For example: $ ln -s $HOME/gnu/src/gnulib.git/gnulib-tool $HOME/bin/gnulib-tool 1.2 Git Checkout ================ Gnulib is available for anonymous checkout. In any Bourne-shell the following should work: $ git clone git://git.sv.gnu.org/gnulib.git For a read-write checkout you need to have a login on 'savannah.gnu.org' and be a member of the Gnulib project at . Then, instead of the URL , use the URL 'ssh://USER@git.sv.gnu.org/srv/git/gnulib' where USER is your login name on savannah.gnu.org. git resources: Overview: Homepage: When you use 'git annotate' or 'git blame' with Gnulib, it's recommended that you use the '-w' option, in order to ignore massive whitespace changes that happened in 2009. 1.3 Keeping Up-to-date ====================== The best way to work with Gnulib is to check it out of git. To synchronize, you can use 'git pull'. Subscribing to the mailing list will help you to plan when to update your local copy of Gnulib (which you use to maintain your software) from git. You can review the archives, subscribe, etc., via . Sometimes, using an updated version of Gnulib will require you to use newer versions of GNU Automake or Autoconf. You may find it helpful to join the autotools-announce mailing list to be advised of such changes. 1.4 Contributing to Gnulib ========================== All software here is copyrighted by the Free Software Foundation--you need to have filled out an assignment form for a project that uses the module for that contribution to be accepted here. If you have a piece of code that you would like to contribute, please email . Generally we are looking for files that fulfill at least one of the following requirements: * If your '.c' and '.h' files define functions that are broken or missing on some other system, we should be able to include it. * If your functions remove arbitrary limits from existing functions (either under the same name, or as a slightly different name), we should be able to include it. If your functions define completely new but rarely used functionality, you should probably consider packaging it as a separate library. 1.4.1 Gnulib licensing ---------------------- Gnulib contains code both under GPL and LGPL. Because several packages that use Gnulib are GPL, the files state they are licensed under GPL. However, to support LGPL projects as well, you may use some of the files under LGPL. The "License:" information in the files under modules/ clarifies the real license that applies to the module source. Keep in mind that if you submit patches to files in Gnulib, you should license them under a compatible license, which means that sometimes the contribution will have to be LGPL, if the original file is available under LGPL via a "License: LGPL" information in the projects' modules/ file. 1.4.2 Indent with spaces not TABs --------------------------------- We use space-only indentation in nearly all files. This includes all '*.h', '*.c', '*.y' files, except for the 'regex' module. Makefile and ChangeLog files are excluded, since TAB characters are part of their format. In order to tell your editor to produce space-only indentation, you can use these instructions. * For Emacs: Add these lines to your Emacs initialization file ('$HOME/.emacs' or similar): ;; In Gnulib, indent with spaces everywhere (not TABs). ;; Exceptions: Makefile and ChangeLog modes. (add-hook 'find-file-hook '(lambda () (if (and buffer-file-name (string-match "/gnulib\\>" (buffer-file-name)) (not (string-equal mode-name "Change Log")) (not (string-equal mode-name "Makefile"))) (setq indent-tabs-mode nil)))) * For vi (vim): Add these lines to your '$HOME/.vimrc' file: " Don't use tabs for indentation. Spaces are nicer to work with. set expandtab For Makefile and ChangeLog files, compensate for this by adding this to your '$HOME/.vim/after/indent/make.vim' file, and similarly for your '$HOME/.vim/after/indent/changelog.vim' file: " Use tabs for indentation, regardless of the global setting. set noexpandtab * For Eclipse: In the "Window|Preferences" dialog (or "Eclipse|Preferences" dialog on Mac OS), 1. Under "General|Editors|Text Editors", select the "Insert spaces for tabs" checkbox. 2. Under "C/C++|Code Style", select a code style profile that has the "Indentation|Tab policy" combobox set to "Spaces only", such as the "GNU [built-in]" policy. If you use the GNU indent program, pass it the option '--no-tabs'. 1.4.3 How to add a new module ----------------------------- * Add the header files and source files to 'lib/'. * If the module needs configure-time checks, write an Autoconf macro for it in 'm4/MODULE.m4'. See 'm4/README' for details. * Write a module description 'modules/MODULE', based on 'modules/TEMPLATE'. * If the module contributes a section to the end-user documentation, put this documentation in 'doc/MODULE.texi' and add it to the "Files" section of 'modules/MODULE'. Most modules don't do this; they have only documentation for the programmer (= Gnulib user). Such documentation usually goes into the 'lib/' source files. It may also go into 'doc/'; but don't add it to the module description in this case. * Add the module to the list in 'MODULES.html.sh'. You can test that a module builds correctly with: $ ./gnulib-tool --create-testdir --dir=/tmp/testdir module1 ... moduleN $ cd /tmp/testdir $ ./configure && make Other things: * Check the license and copyright year of headers. * Check that the source code follows the GNU coding standards; see . * Add source files to 'config/srclist*' if they are identical to upstream and should be upgraded in Gnulib whenever the upstream source changes. * Include header files in source files to verify the function prototypes. * Make sure a replacement function doesn't cause warnings or clashes on systems that have the function. * Autoconf functions can use 'gl_*' prefix. The 'AC_*' prefix is for autoconf internal functions. * Build files only if they are needed on a platform. Look at the 'alloca' and 'fnmatch' modules for how to achieve this. If for some reason you cannot do this, and you have a '.c' file that leads to an empty '.o' file on some platforms (through some big '#if' around all the code), then ensure that the compilation unit is not empty after preprocessing. One way to do this is to '#include ' or '' before the big '#if'. 1.4.4 Portability guidelines ---------------------------- Gnulib code is intended to be portable to a wide variety of platforms, not just GNU platforms. See the documentation section "Target Platforms" for details. Many Gnulib modules exist so that applications need not worry about undesirable variability in implementations. For example, an application that uses the 'malloc' module need not worry about 'malloc (0)' returning 'NULL' on some Standard C platforms; and 'time_r' users need not worry about 'localtime_r' returning 'int' (not 'char *') on some platforms that predate POSIX 1003.1-2001. Currently we assume at least a freestanding C89 compiler, possibly operating with a C library that predates C89. The oldest environments currently ported to are probably HP-UX 10.20 and IRIX 5.3, though we are not testing these platforms very often. Because we assume a freestanding C89 compiler, Gnulib code can include '', '', '', and '' unconditionally. It can also assume the existence of '', '', '', '', '', '', '', '', and ''. Similarly, many modules include '' even though it's not even in C99; that's OK since '' has been around nearly forever. Even if the include files exist, they may not conform to C89. However, GCC has a 'fixincludes' script that attempts to fix most C89-conformance problems. So Gnulib currently assumes include files largely conform to C89 or better. People still using ancient hosts should use fixincludes or fix their include files manually. Even if the include files conform to C89, the library itself may not. For example, 'strtod' and 'mktime' have some bugs on some platforms. You can work around some of these problems by requiring the relevant modules, e.g., the Gnulib 'mktime' module supplies a working and conforming 'mktime'. The GNU coding standards allow one departure from strict C99: Gnulib code can assume that standard internal types like 'size_t' are no wider than 'long'. POSIX 1003.1-2001 and the GNU coding standards both require 'int' to be at least 32 bits wide, so Gnulib code assumes this as well. Gnulib code makes the following additional assumptions: * Signed integer arithmetic is two's complement. Previously, Gnulib code sometimes assumed that signed integer arithmetic wraps around, but modern compiler optimizations sometimes do not guarantee this, and Gnulib code with this assumption is now considered to be questionable. *Note Integer Properties::. Some Gnulib modules contain explicit support for the other signed integer representations allowed by C99 (ones' complement and signed magnitude), but these modules are the exception rather than the rule. All practical Gnulib targets use two's complement. * There are no "holes" in integer values: all the bits of an integer contribute to its value in the usual way. * Addresses and sizes behave as if objects reside in a flat address space. In particular: * If two nonoverlapping objects have sizes S and T represented as 'size_t' values, then 'S + T' cannot overflow. * A pointer P points within an object O if and only if '(char *) &O <= (char *) P && (char *) P < (char *) (&O + 1)'. * If an existing object has size S, and if T is sufficiently small (e.g., 8 KiB), then 'S + T' cannot overflow. Overflow in this case would mean that the rest of your program fits into T bytes, which can't happen in realistic flat-address-space hosts. * Objects with all bits zero are treated as 0 or NULL. For example, 'memset (A, 0, sizeof A)' initializes an array 'A' of pointers to NULL. * Adding zero to a null pointer does not change the pointer. For example, '0 + (char *) NULL == (char *) NULL'. The above assumptions are not required by the C or POSIX standards but hold on all practical porting targets that we're familiar with. If you have a porting target where these assumptions are not true, we'd appreciate hearing of any fixes. We need fixes that do not increase runtime overhead on standard hosts and that are relatively easy to maintain. With the above caveats, Gnulib code should port without problem to new hosts, e.g., hosts conforming to C99 or to recent POSIX standards. Hence Gnulib code should avoid using constructs (e.g., undeclared functions return 'int') that do not conform to C99. 1.5 High Quality ================ We develop and maintain a testsuite for Gnulib. The goal is to have a 100% firm interface so that maintainers can feel free to update to the code in git at _any_ time and know that their application will not break. This means that before any change can be committed to the repository, a test suite program must be produced that exposes the bug for regression testing. All experimental work should be done on branches to help promote this. 2 Philosophy ************ Gnulib's design and development philosophy is organized around steady, collaborative, and open development of reusable modules that are suitable for a reasonably wide variety of platforms. 2.1 Benefits of using Gnulib ============================ Gnulib is useful to enhance various aspects of a package: * Portability: With Gnulib, a package maintainer can program against the POSIX and GNU libc APIs and nevertheless expect good portability to platforms that don't implement POSIX. * Maintainability: When a package uses modules from Gnulib instead of code written specifically for that package, the maintainer has less code to maintain. * Security: Gnulib provides functions that are immune against vulnerabilities that plague the uses of the corresponding commonplace functions. For example, 'asprintf', 'canonicalize_file_name' are not affected by buffer sizing problems that affect 'sprintf', 'realpath'. 'openat' does not have the race conditions that 'open' has. Etc. * Reliability: Gnulib provides functions that combine a call to a system function with a check of the result. Examples are 'xalloc', 'xprintf', 'xstrtod', 'xgetcwd'. * Structure: Gnulib offers a way to structure code into modules, typically one include file, one source code file, and one autoconf macro for each functionality. Modularity helps maintainability. 2.2 Library vs. Reusable Code ============================= Classical libraries are installed as binary object code. Gnulib is different: It is used as a source code library. Each package that uses Gnulib thus ships with part of the Gnulib source code. The used portion of Gnulib is tailored to the package: A build tool, called 'gnulib-tool', is provided that copies a tailored subset of Gnulib into the package. 2.3 Portability and Application Code ==================================== One of the goals of Gnulib is to make portable programming easy, on the basis of the standards relevant for GNU (and Unix). The objective behind that is to avoid a fragmentation of the user community into disjoint user communities according to the operating system, and instead allow synergies between users on different operating systems. Another goal of Gnulib is to provide application code that can be shared between several applications. Some people wonder: "What? glibc doesn't have a function to copy a file?" Indeed, the scope of a system's libc is to implement the relevant standards (ISO C, POSIX) and to provide access functions to the kernel's system calls, and little more. There is no clear borderline between both areas. For example, Gnulib has a facility for generating the name of backup files. While this task is entirely at the application level--no standard specifies an API for it--the nai"ve code has some portability problems because on some platforms the length of file name components is limited to 30 characters or so. Gnulib handles that. Similarly, Gnulib has a facility for executing a command in a subprocess. It is at the same time a portability enhancement (it works on GNU, Unix, and Windows, compared to the classical 'fork'/'exec' idiom which is not portable to Windows), as well as an application aid: it takes care of redirecting stdin and/or stdout if desired, and emits an error message if the subprocess failed. 2.4 Target Platforms ==================== Gnulib supports a number of platforms that we call the "reasonable portability targets". This class consists of widespread operating systems, for three years after their last availability, or--for proprietary operating systems--as long as the vendor provides commercial support for it. Already existing Gnulib code for older operating systems is usually left in place for longer than these three years. So it comes that programs that use Gnulib run pretty well also on these older operating systems. Some operating systems are not very widespread, but are Free Software and are actively developed. Such platforms are also supported by Gnulib, if that OS's developers community keeps in touch with the Gnulib developers, by providing bug reports, analyses, or patches. For such platforms, Gnulib supports only the versions of the last year or the last few months, depending on the maturity of said OS project, the number of its users, and how often these users upgrade. Niche operating systems are generally unsupported by Gnulib, unless some of their developers or users contribute support to Gnulib. The degree of support Gnulib guarantees for a platform depends on the amount of testing it gets from volunteers. Platforms on which Gnulib is frequently tested are the best supported. Then come platforms with occasional testing, then platforms which are rarely tested. Usually, we fix bugs when they are reported. Except that some rarely tested platforms are also low priority; bug fixes for these platforms can take longer. As of 2011, the list of supported platforms is the following: * glibc systems. With glibc 2.8 or newer, they are frequently tested. With glibc 2.3 or newer, they are occasionally tested. * Mac OS X. In versions 10.5 and 10.6, it's frequently tested. In version 10.4, it's rarely tested. * FreeBSD 6.0 or newer is occasionally tested. FreeBSD 5.x is rarely tested. * NetBSD 5.0 or newer is occasionally tested. NetBSD 3.0 or newer is rarely tested. * OpenBSD 4.0 or newer is occasionally tested. OpenBSD 3.8 or newer is rarely tested. * AIX 6.1 or newer is occasionally tested. AIX 5.1 or newer is rarely tested. * HP-UX 11.11 or newer is occasionally tested. HP-UX 11.00 is rarely tested. HP-UX 10.20 is rarely tested and low priority. * IRIX 6.5 is occasionally tested. IRIX 5.3 is rarely tested and low priority. * OSF/1 5.1 is occasionally tested. OSF/1 4.0 is rarely tested and low priority. * Solaris 8 and newer are occasionally tested. Solaris 7 is rarely tested. Solaris 2.6 and older are rarely tested and low priority. * Cygwin 1.7.x is frequently tested. Cygwin 1.5.x is occasionally tested. * mingw is frequently tested. But note that some modules are currently unsupported on mingw: 'mgetgroups', 'getugroups', 'idcache', 'userspec', 'openpty', 'login_tty', 'forkpty', 'pt_chown', 'grantpt', 'pty', 'savewd', 'mkancesdirs', 'mkdir-p', 'euidaccess', 'faccessat'. The versions of Windows that are supported are Windows XP and newer. Only the latest version of mingw is tested; older versions are not supported. * Native Windows, with MSVC as compiler, is rarely tested and low priority. * mingw in 64-bit mode is not tested and low priority so far. * Interix 6.1 is rarely tested, and requires the 'suacomp' library () in version 0.6.8 or newer. Interix 3.5 is not tested. * Haiku is rarely tested, BeOS is not tested and low priority. * uClibc on Linux is rarely tested. * QNX is not tested and low priority. Gnulib supports these operating systems only in an unvirtualized environment. When you run an OS inside a virtual machine, you have to be aware that the virtual machine can bring in bugs of its own. For example, floating-point operations on Solaris can behave slightly differently in QEMU than on real hardware. And Haiku's 'bash' program misbehaves in VirtualBox 3, whereas it behaves fine in VirtualBox 4. Similarly, running native Windows binaries on GNU/Linux under WINE is rarely tested and low priority: WINE has a set of behaviours and bugs that is slightly different from native Windows. The following platforms are not supported by Gnulib. The cost of supporting them would exceed the benefit because they are rarely used, or poorly documented, or have been supplanted by other platforms, or diverge too much from POSIX, or some combination of these and other factors. Please don't bother sending us patches for them. * Windows 95/98/ME. * DJGPP and EMX (the 32-bit operating systems running in DOS). * MSDOS (the 16-bit operating system). * Windows Mobile, Symbian OS, iOS. 2.5 Modules =========== Gnulib is divided into modules. Every module implements a single facility. Modules can depend on other modules. A module consists of a number of files and a module description. The files are copied by 'gnulib-tool' into the package that will use it, usually verbatim, without changes. Source code files (.h, .c files) reside in the 'lib/' subdirectory. Autoconf macro files reside in the 'm4/' subdirectory. Build scripts reside in the 'build-aux/' subdirectory. The module description contains the list of files; 'gnulib-tool' copies these files. It contains the module's dependencies; 'gnulib-tool' installs them as well. It also contains the autoconf macro invocation (usually a single line or nothing at all); 'gnulib-tool' ensures this is invoked from the package's 'configure.ac' file. And also a 'Makefile.am' snippet; 'gnulib-tool' collects these into a 'Makefile.am' for the tailored Gnulib part. The module description and include file specification are for documentation purposes; they are combined into 'MODULES.html'. The module system serves two purposes: 1. It ensures consistency of the used autoconf macros and 'Makefile.am' rules with the source code. For example, source code which uses the 'getopt_long' function--this is a common way to implement parsing of command line options in a way that complies with the GNU standards--needs the source code ('lib/getopt.c' and others), the autoconf macro which detects whether the system's libc already has this function (in 'm4/getopt.m4'), and a few 'Makefile.am' lines that create the substitute 'getopt.h' if not. These three pieces belong together. They cannot be used without each other. The module description and 'gnulib-tool' ensure that they are copied altogether into the destination package. 2. It allows for scalability. It is well-known since the inception of the MODULA-2 language around 1978 that dissection into modules with dependencies allows for building large sets of code in a maintainable way. The maintainability comes from the facts that: * Every module has a single purpose; you don't worry about other parts of the program while creating, reading or modifying the code of a module. * The code you have to read in order to understand a module is limited to the source of the module and the .h files of the modules listed as dependencies. It is for this reason also that we recommend to put the comments describing the functions exported by a module into its .h file. In other words, the module is the elementary unit of code in Gnulib, comparable to a class in object-oriented languages like Java or C#. The module system is the basis of 'gnulib-tool'. When 'gnulib-tool' copies a part of Gnulib into a package, it first compiles a module list, starting with the requested modules and adding all the dependencies, and then collects the files, 'configure.ac' snippets and 'Makefile.am' snippets. 2.6 Various Kinds of Modules ============================ There are modules of various kinds in Gnulib. For a complete list of the modules, see in 'MODULES.html'. 2.6.1 Support for ISO C or POSIX functions. ------------------------------------------- When a function is not implemented by a system, the Gnulib module provides an implementation under the same name. Examples are the 'snprintf' and 'readlink' modules. Similarly, when a function is not correctly implemented by a system, Gnulib provides a replacement. For functions, we use the pattern #if !HAVE_WORKING_FOO # define foo rpl_foo #endif and implement the 'foo' function under the name 'rpl_foo'. This renaming is needed to avoid conflicts at compile time (in case the system header files declare 'foo') and at link/run time (because the code making use of 'foo' could end up residing in a shared library, and the executable program using this library could be defining 'foo' itself). For header files, such as 'stdbool.h' or 'stdint.h', we provide the substitute only if the system doesn't provide a correct one. The template of this replacement is distributed in a slightly different name, with '.in' inserted before the '.h' extension, so that on systems which do provide a correct header file the system's one is used. 2.6.2 Enhancements of ISO C or POSIX functions ---------------------------------------------- These are sometimes POSIX functions with GNU extensions also found in glibc--examples: 'getopt', 'fnmatch'--and often new APIs--for example, for all functions that allocate memory in one way or the other, we have variants which also include the error checking against the out-of-memory condition. 2.6.3 Portable general use facilities ------------------------------------- Examples are a module for copying a file--the portability problems relate to the copying of the file's modification time, access rights, and extended attributes--or a module for extracting the tail component of a file name--here the portability to native Windows requires a different API than the classical POSIX 'basename' function. 2.6.4 Reusable application code ------------------------------- Examples are an error reporting function, a module that allows output of numbers with K/M/G suffixes, or cryptographic facilities. 2.6.5 Object oriented classes ----------------------------- Examples are data structures like 'list', or abstract output stream classes that work around the fact that an application cannot implement an stdio 'FILE' with its logic. Here, while staying in C, we use implementation techniques like tables of function pointers, known from the C++ language or from the Linux kernel. 2.6.6 Interfaces to external libraries -------------------------------------- Examples are the 'iconv' module, which interfaces to the 'iconv' facility, regardless whether it is contained in libc or in an external 'libiconv'. Or the 'readline' module, which interfaces to the GNU readline library. 2.6.7 Build / maintenance infrastructure ---------------------------------------- An example is the 'maintainer-makefile' module, which provides extra Makefile tags for maintaining a package. 2.7 Collaborative Development ============================= Gnulib is maintained collaboratively. The mailing list is ''. Be warned that some people on the list may be very active at some times and unresponsive at other times. Every module has one or more maintainers. While issues are discussed collaboratively on the list, the maintainer of a module nevertheless has a veto right regarding changes in his module. All patches should be posted the list, regardless whether they are proposed patches or whether they are committed immediately by the maintainer of the particular module. The purpose is not only to inform the other users of the module, but mainly to allow peer review. It is not uncommon that several people contribute comments or spot bugs after a patch was proposed. Conversely, if you are using Gnulib, and a patch is posted that affects one of the modules that your package uses, you have an interest in proofreading the patch. 2.8 Copyright ============= Most modules are under the GPL. Some, mostly modules which can reasonably be used in libraries, are under LGPL. The source files always say "GPL", but the real license specification is in the module description file. If the module description file says "GPL", it means "GPLv3+" (GPLv3 or newer, at the licensee's choice); if it says "LGPL", it means "LGPLv3+" (LGPLv3 or newer, at the licensee's choice). More precisely, the license specification in the module description file applies to the files in 'lib/' and 'build-aux/'. Different licenses apply to files in special directories: 'modules/' Module description files are under this copyright: Copyright (C) 20XX-20YY Free Software Foundation, Inc. Copying and distribution of this file, with or without modification, in any medium, are permitted without royalty provided the copyright notice and this notice are preserved. 'm4/' Autoconf macro files are under this copyright: Copyright (C) 20XX-20YY Free Software Foundation, Inc. This file is free software; the Free Software Foundation gives unlimited permission to copy and/or distribute it, with or without modifications, as long as this notice is preserved. 'tests/' If a license statement is not present in a test module, the test files are under GPL. Even if the corresponding source module is under LGPL, this is not a problem, since compiled tests are not installed by "make install". 'doc/' Documentation files are under this copyright: Copyright (C) 2004-20YY Free Software Foundation, Inc. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled "GNU Free Documentation License". If you want to use some Gnulib modules under LGPL, you can do so by passing the option '--lgpl' to 'gnulib-tool'. This will replace the GPL header with an LGPL header while copying the source files to your package. Similarly, if you want some Gnulib modules under LGPLv2+ (Lesser GPL version 2.1 or newer), you can do so by passing the option '--lgpl=2' to 'gnulib-tool'. Keep in mind that when you submit patches to files in Gnulib, you should license them under a compatible license. This means that sometimes the contribution will have to be LGPL, if the original file is available under LGPL. You can find out about it by looking for a "License: LGPL" information in the corresponding module description. 2.9 Steady Development ====================== Gnulib modules are continually adapted, to match new practices, to be consistent with newly added modules, or simply as a response to build failure reports. Gnulib is available in two qualities: * There is the newest version of Gnulib from the Git repository. * We also make stable releases every two months, at . If you are willing to report an occasional regression, we recommend to use the newest version always, except in periods of major changes. Most Gnulib users do this. If you prefer stable releases, please use the newest stable release. 2.10 Openness ============= Gnulib is open in the sense that we gladly accept contributions if they are generally useful, well engineered, and if the contributors have signed the obligatory papers with the FSF. The module system is open in the sense that a package using Gnulib can 1. locally patch or override files in Gnulib, 2. locally add modules that are treated like Gnulib modules by 'gnulib-tool'. This is achieved by the '--local-dir' option of 'gnulib-tool' (*note Extending Gnulib::). 3 Invoking gnulib-tool ********************** The 'gnulib-tool' command is the recommended way to import Gnulib modules. It is possible to borrow Gnulib modules in a package without using 'gnulib-tool', relying only on the meta-information stored in the 'modules/*' files, but with a growing number of modules this becomes tedious. 'gnulib-tool' simplifies the management of source files, 'Makefile.am's and 'configure.ac' in packages incorporating Gnulib modules. 'gnulib-tool' is not installed in a standard directory that is contained in the 'PATH' variable. It needs to be run directly in the directory that contains the Gnulib source code. You can do this either by specifying the absolute filename of 'gnulib-tool', or you can also use a symbolic link from a place inside your 'PATH' to the 'gnulib-tool' file of your preferred and most up-to-date Gnulib checkout, like this: $ ln -s $HOME/gnu/src/gnulib.git/gnulib-tool $HOME/bin/gnulib-tool Run 'gnulib-tool --help' for information. To get familiar with 'gnulib-tool' without affecting your sources, you can also try some commands with the option '--dry-run'; then 'gnulib-tool' will only report which actions it would perform in a real run without changing anything. 3.1 Finding modules =================== There are three ways of finding the names of Gnulib modules that you can use in your package: * You have the complete module list, sorted according to categories, in . * If you are looking for a particular POSIX header or function replacement, look in the chapters *note Header File Substitutes:: and *note Function Substitutes::. For headers and functions that are provided by Glibc but not standardized by POSIX, look in the chapters *note Glibc Header File Substitutes:: and *note Glibc Function Substitutes::. * If you have already found the source file in Gnulib and are looking for the module that contains this source file, you can use the command 'gnulib-tool --find FILENAME'. 3.2 Initial import ================== Gnulib assumes that your project uses Autoconf. When using Gnulib, you will need to have Autoconf and Automake among your build tools. Note that while the use of Automake in your project's top level directory is an easy way to fulfil the Makefile conventions of the GNU coding standards, Gnulib does not require it. But when you use Gnulib, Automake will be used at least in a subdirectory of your project. Invoking 'gnulib-tool --import' will copy source files, create a 'Makefile.am' to build them, generate a file 'gnulib-comp.m4' with Autoconf M4 macro declarations used by 'configure.ac', and generate a file 'gnulib-cache.m4' containing the cached specification of how Gnulib is used. Our example will be a library that uses Autoconf, Automake and Libtool. It calls 'strdup', and you wish to use gnulib to make the package portable to C89 and C99 (which don't have 'strdup'). ~/src/libfoo$ gnulib-tool --import strdup Module list with included dependencies: absolute-header extensions strdup string File list: lib/dummy.c lib/strdup.c lib/string.in.h m4/absolute-header.m4 m4/extensions.m4 m4/gnulib-common.m4 m4/strdup.m4 m4/string_h.m4 Creating directory ./lib Creating directory ./m4 Copying file lib/dummy.c Copying file lib/strdup.c Copying file lib/string.in.h Copying file m4/absolute-header.m4 Copying file m4/extensions.m4 Copying file m4/gnulib-common.m4 Copying file m4/gnulib-tool.m4 Copying file m4/strdup.m4 Copying file m4/string_h.m4 Creating lib/Makefile.am Creating m4/gnulib-cache.m4 Creating m4/gnulib-comp.m4 Finished. You may need to add #include directives for the following .h files. #include Don't forget to - add "lib/Makefile" to AC_CONFIG_FILES in ./configure.ac, - mention "lib" in SUBDIRS in Makefile.am, - mention "-I m4" in ACLOCAL_AMFLAGS in Makefile.am, - invoke gl_EARLY in ./configure.ac, right after AC_PROG_CC, - invoke gl_INIT in ./configure.ac. ~/src/libfoo$ By default, the source code is copied into 'lib/' and the M4 macros in 'm4/'. You can override these paths by using '--source-base=DIRECTORY' and '--m4-base=DIRECTORY'. Some modules also provide other files necessary for building. These files are copied into the directory specified by 'AC_CONFIG_AUX_DIR' in 'configure.ac' or by the '--aux-dir=DIRECTORY' option. If neither is specified, the current directory is assumed. 'gnulib-tool' can make symbolic links instead of copying the source files. The option to specify for this is '--symlink', or '-s' for short. This can be useful to save a few kilobytes of disk space. But it is likely to introduce bugs when 'gnulib' is updated; it is more reliable to use 'gnulib-tool --update' (see below) to update to newer versions of 'gnulib'. Furthermore it requires extra effort to create self-contained tarballs, and it may disturb some mechanism the maintainer applies to the sources. For these reasons, this option is generally discouraged. 'gnulib-tool' will overwrite any pre-existing files, in particular 'Makefile.am'. It is also possible to separate the generated 'Makefile.am' content (for building the gnulib library) into a separate file, say 'gnulib.mk', that can be included by your handwritten 'Makefile.am', but this is a more advanced use of 'gnulib-tool'. Consequently, it is a good idea to choose directories that are not already used by your projects, to separate gnulib imported files from your own files. This approach is also useful if you want to avoid conflicts between other tools (e.g., 'gettextize' that also copy M4 files into your package. Simon Josefsson successfully uses a source base of 'gl/', and a M4 base of 'gl/m4/', in several packages. After the '--import' option on the command line comes the list of Gnulib modules that you want to incorporate in your package. The names of the modules coincide with the filenames in Gnulib's 'modules/' directory. Some Gnulib modules depend on other Gnulib modules. 'gnulib-tool' will automatically add the needed modules as well; you need not list them explicitly. 'gnulib-tool' will also memorize which dependent modules it has added, so that when someday a dependency is dropped, the implicitly added module is dropped as well (unless you have explicitly requested that module). If you want to cut a dependency, i.e., not add a module although one of your requested modules depends on it, you may use the option '--avoid=MODULE' to do so. Multiple uses of this option are possible. Of course, you will then need to implement the same interface as the removed module. A few manual steps are required to finish the initial import. 'gnulib-tool' printed a summary of these steps. First, you must ensure Autoconf can find the macro definitions in 'gnulib-comp.m4'. Use the 'ACLOCAL_AMFLAGS' specifier in your top-level 'Makefile.am' file, as in: ACLOCAL_AMFLAGS = -I m4 You are now ready to call the M4 macros in 'gnulib-comp.m4' from 'configure.ac'. The macro 'gl_EARLY' must be called as soon as possible after verifying that the C compiler is working. Typically, this is immediately after 'AC_PROG_CC', as in: ... AC_PROG_CC gl_EARLY ... If you are using 'AC_PROG_CC_STDC', the macro 'gl_EARLY' must be called after it, like this: ... AC_PROG_CC AC_PROG_CC_STDC gl_EARLY ... The core part of the gnulib checks are done by the macro 'gl_INIT'. Place it further down in the file, typically where you normally check for header files or functions. It must come after other checks which may affect the compiler invocation, such as 'AC_MINIX'. For example: ... # For gnulib. gl_INIT ... 'gl_INIT' will in turn call the macros related with the gnulib functions, be it specific gnulib macros, like 'gl_FUNC_ALLOCA' or autoconf or automake macros like 'AC_FUNC_ALLOCA' or 'AM_FUNC_GETLINE'. So there is no need to call those macros yourself when you use the corresponding gnulib modules. You must also make sure that the gnulib library is built. Add the 'Makefile' in the gnulib source base directory to 'AC_CONFIG_FILES', as in: AC_CONFIG_FILES(... lib/Makefile ...) You must also make sure that 'make' will recurse into the gnulib directory. To achieve this, add the gnulib source base directory to a 'SUBDIRS' Makefile.am statement, as in: SUBDIRS = lib or if you, more likely, already have a few entries in 'SUBDIRS', you can add something like: SUBDIRS += lib Finally, you have to add compiler and linker flags in the appropriate source directories, so that you can make use of the gnulib library. Since some modules ('getopt', for example) may copy files into the build directory, 'top_builddir/lib' is needed as well as 'top_srcdir/lib'. For example: ... AM_CPPFLAGS = -I$(top_builddir)/lib -I$(top_srcdir)/lib ... LDADD = lib/libgnu.a ... Don't forget to '#include' the various header files. In this example, you would need to make sure that '#include ' is evaluated when compiling all source code files, that want to make use of 'strdup'. In the usual case where Autoconf is creating a 'config.h' file, you should include 'config.h' first, before any other include file. That way, for example, if 'config.h' defines 'restrict' to be the empty string on a pre-C99 host, or a macro like '_FILE_OFFSET_BITS' that affects the layout of data structures, the definition is consistent for all include files. Also, on some platforms macros like '_FILE_OFFSET_BITS' and '_GNU_SOURCE' may be ineffective, or may have only a limited effect, if defined after the first system header file is included. Finally, note that you cannot use 'AC_LIBOBJ' or 'AC_REPLACE_FUNCS' in your 'configure.ac' and expect the resulting object files to be automatically added to 'lib/libgnu.a'. This is because your 'AC_LIBOBJ' and 'AC_REPLACE_FUNCS' invocations from 'configure.ac' augment a variable '@LIBOBJS@' (and/or '@LTLIBOBJS@' if using Libtool), whereas 'lib/libgnu.a' is built from the contents of a different variable, usually '@gl_LIBOBJS@' (or '@gl_LTLIBOBJS@' if using Libtool). 3.3 Modified imports ==================== You can at any moment decide to use Gnulib differently than the last time. There are two ways to change how Gnulib is used. Which one you'll use, depends on where you keep track of options and module names that you pass to 'gnulib-tool'. * If you store the options and module names in a file under your own control, such as 'autogen.sh', 'bootstrap', 'bootstrap.conf', or similar, simply invoke 'gnulib-tool' again, with modified options and more or fewer module names. * 'gnulib-tool' remembers which modules were used last time. If you want to rely on 'gnulib-tool''s own memory of the last used options and module names, you can use the commands 'gnulib-tool --add-import' and 'gnulib-tool --remove-import'. So, if you only want to use more Gnulib modules, simply invoke 'gnulib-tool --add-import NEW-MODULES'. The list of modules that you pass after '--add-import' is _added_ to the previous list of modules. Similarly, if you want to use fewer Gnulib modules, simply invoke 'gnulib-tool --remove-import UNNEEDED-MODULES'. The list of modules that you pass after '--remove-import' is _removed_ from the previous list of modules. Note that if a module is then still needed as dependency of other modules, it will be used nevertheless. If you want to _really_ not use a module any more, regardless of whether other modules may need it, you need to use the '--avoid' option. For other changes, such as different choices of '--lib', '--source-base' or '--aux-dir', the normal way is to modify manually the file 'gnulib-cache.m4' in the M4 macros directory, then launch 'gnulib-tool --add-import'. The only change for which this doesn't work is a change of the '--m4-base' directory. Because, when you pass a different value of '--m4-base', 'gnulib-tool' will not find the previous 'gnulib-cache.m4' file any more. A possible solution is to manually copy the 'gnulib-cache.m4' into the new M4 macro directory. In the 'gnulib-cache.m4' file, the macros have the following meaning: 'gl_MODULES' The argument is a space separated list of the requested modules, not including dependencies. 'gl_AVOID' The argument is a space separated list of modules that should not be used, even if they occur as dependencies. Corresponds to the '--avoid' command line argument. 'gl_SOURCE_BASE' The argument is the relative file name of the directory containing the gnulib source files (mostly *.c and *.h files). Corresponds to the '--source-base' command line argument. 'gl_M4_BASE' The argument is the relative file name of the directory containing the gnulib M4 macros (*.m4 files). Corresponds to the '--m4-base' command line argument. 'gl_TESTS_BASE' The argument is the relative file name of the directory containing the gnulib unit test files. Corresponds to the '--tests-base' command line argument. 'gl_LIB' The argument is the name of the library to be created. Corresponds to the '--lib' command line argument. 'gl_LGPL' The presence of this macro without arguments corresponds to the '--lgpl' command line argument. The presence of this macro with an argument (whose value must be 2 or 3) corresponds to the '--lgpl=ARG' command line argument. 'gl_LIBTOOL' The presence of this macro corresponds to the '--libtool' command line argument and to the absence of the '--no-libtool' command line argument. It takes no arguments. 'gl_MACRO_PREFIX' The argument is the prefix to use for macros in the 'gnulib-comp.m4' file. Corresponds to the '--macro-prefix' command line argument. 3.4 Simple update ================= When you want to update to a more recent version of Gnulib, without changing the list of modules or other parameters, a simple call does it: $ gnulib-tool --add-import This will create, update or remove files, as needed. Note: From time to time, changes are made in Gnulib that are not backward compatible. When updating to a more recent Gnulib, you should consult Gnulib's 'NEWS' file to check whether the incompatible changes affect your project. 3.5 Changing your sources for use with Gnulib ============================================= Gnulib contains some header file overrides. This means that when building on systems with deficient header files in '/usr/include/', it may create files named 'string.h', 'stdlib.h', 'stdint.h' or similar in the build directory. In the other source directories of your package you will usually pass '-I' options to the compiler, so that these Gnulib substitutes are visible and take precedence over the files in '/usr/include/'. These Gnulib substitute header files rely on '' being already included. Furthermore '' must be the first include in every compilation unit. This means that to _all your source files_ and likely also to _all your tests source files_ you need to add an '#include ' at the top. Which source files are affected? Exactly those whose compilation includes a '-I' option that refers to the Gnulib library directory. This is annoying, but inevitable: On many systems, '' is used to set system dependent flags (such as '_GNU_SOURCE' on GNU systems), and these flags have no effect after any system header file has been included. 3.6 Using Gnulib for both a library and a binary ================================================ Your project might build both a library and some accompanying binaries in the same source tree. In that case you might want to use different modules for the library than for the binaries. Typically the binaries might want to make use of 'getopt-posix' or 'version-etc', while the library wants to stay clear of these modules for technical or licensing reasons. Let's assume that your project contains a 'lib' directory where the source of the library resides and a 'src' directory for the sources of the binaries as follows. . |-- configure.ac |-- lib | |-- foo.c | `-- Makefile.am |-- Makefile.am `-- src |-- bar.c `-- Makefile.am You can now add two instances of Gnulib to your project in separate source trees: ~/src/libfoo$ gnulib-tool --import --lib=libgnu --source-base=gnulib \ --m4-base=gnulib/m4 --macro-prefix=gl strndup ~/src/libfoo$ gnulib-tool --import --lib=libgnutools \ --source-base=src/gnulib --m4-base=src/gnulib/m4 \ --macro-prefix=gl_tools getopt-gnu The first one will import the module 'strndup' in 'gnulib' and the second one will import 'getopt-gnu' in 'src/gnulib' and you will end up with the following source tree (many files omitted in the interest of brevity): . |-- configure.ac |-- gnulib | |-- m4 | |-- strndup.c |-- lib | |-- foo.c | `-- Makefile.am |-- Makefile.am `-- src |-- bar.c |-- gnulib | |-- getopt.c | |-- getopt.in.h | |-- m4 `-- Makefile.am Integration with your code is basically the same as outlined in *note Initial import:: with the one exception that you have to add both the macro 'gl_EARLY' and the macro 'gl_tools_EARLY' to your 'configure.ac' (and of course also both macros 'gl_INIT' and 'gl_tools_INIT'). Obviously the name of the second macro is dependent on the value of the '--macro-prefix' option in your 'gnulib-tool' invocation. ... AC_PROG_CC gl_EARLY gl_tools_EARLY ... # For gnulib. gl_INIT gl_tools_INIT ... Also as outlined in *note Initial import:: you will have to add compiler and linker flags. For the library you might have to add something along the line of the following to your 'Makefile.am': ... AM_CPPFLAGS = -I$(top_srcdir)/gnulib -I$(top_builddir)/gnulib ... libfoo_la_LIBADD = $(top_builddir)/gnulib/libgnu.la ... Correspondingly for the binary you will have to add something along the lines of to the following: ... AM_CPPFLAGS = -I$(top_srcdir)/src/gnulib -I$(top_builddir)/src/gnulib ... LIBADD = $(top_builddir)/src/gnulib/libgnutools.la ... The name of the library that you have pass in the linker option depends on the '--lib' option in 'gnulib-tool' invocation. 3.7 Caveat: 'gettextize' and 'autopoint' users ============================================== The programs 'gettextize' and 'autopoint', part of GNU 'gettext', import or update the internationalization infrastructure. Some of this infrastructure, namely ca. 20 autoconf macro files and the 'config.rpath' file, is also contained in Gnulib and may be imported by 'gnulib-tool'. The use of 'gettextize' or 'autopoint' will therefore overwrite some of the files that 'gnulib-tool' has imported, and vice versa. Avoiding to use 'gettextize' (manually, as package maintainer) or 'autopoint' (as part of a script like 'autoreconf' or 'autogen.sh') is not the solution: These programs also import the infrastructure in the 'po/' and optionally in the 'intl/' directory. The copies of the conflicting files in Gnulib are more up-to-date than the copies brought in by 'gettextize' and 'autopoint'. When a new 'gettext' release is made, the copies of the files in Gnulib will be updated immediately. The choice of which version of gettext to require depends on the needs of your package. For a package that wants to comply to GNU Coding Standards, the steps are: 1. When you run 'gettextize', always use the 'gettextize' from the matching GNU gettext release. For the most recent Gnulib checkout, this is the newest release found on . For an older Gnulib snapshot, it is the release that was the most recent release at the time the Gnulib snapshot was taken. 2. After running 'gettextize', invoke 'gnulib-tool' and import the 'gettext' module. Also, copy the latest version of gnulib's 'build-aux/po/Makefile.in.in' to your 'po/' directory (this is done for you if you use gnulib's 'bootstrap' script). 3. If you get an error message like '*** error: gettext infrastructure mismatch: using a Makefile.in.in from gettext version ... but the autoconf macros are from gettext version ...', it means that a new GNU gettext release was made, and its autoconf macros were integrated into Gnulib and now mismatch the 'po/' infrastructure. In this case, fetch and install the new GNU gettext release and run 'gettextize' followed by 'gnulib-tool'. On the other hand, if your package is not as concerned with compliance to the latest standards, but instead favors development on stable environments, the steps are: 1. Determine the oldest version of 'gettext' that you intend to support during development (at this time, gnulib recommends going no older than version 0.17). Run 'autopoint' (not 'gettextize') to copy infrastructure into place (newer versions of gettext will install the older infrastructure that you requested). 2. Invoke 'gnulib-tool', and import the 'gettext-h' module. Regardless of which approach you used to get the infrastructure in place, the following steps must then be used to preserve that infrastructure (gnulib's 'bootstrap' script follows these rules): 1. When a script of yours run 'autopoint', invoke 'gnulib-tool' afterwards. 2. When you invoke 'autoreconf' after 'gnulib-tool', make sure to not invoke 'autopoint' a second time, by setting the 'AUTOPOINT' environment variable, like this: $ env AUTOPOINT=true autoreconf --install 3.8 Handling Gnulib's own message translations ============================================== Gnulib provides some functions that emit translatable messages using GNU 'gettext'. The 'gnulib' domain at the Translation Project (http://translationproject.org/) collects translations of these messages, which you should incorporate into your own programs. There are two basic ways to achieve this. The first, and older, method is to list all the source files you use from Gnulib in your own 'po/POTFILES.in' file. This will cause all the relevant translatable strings to be included in your POT file. When you send this POT file to the Translation Project, translators will normally fill in the translations of the Gnulib strings from their "translation memory", and send you back updated PO files. However, this process is error-prone: you might forget to list some source files, or the translator might not be using a translation memory and provide a different translation than another translator, or the translation might not be kept in sync between Gnulib and your package. It is also slow and causes substantial extra work, because a human translator must be in the loop for each language and you will need to incorporate their work on request. For these reasons, a new method was designed and is now recommended. If you pass the '--po-base=DIRECTORY' and '--po-domain=DOMAIN' options to 'gnulib-tool', then 'gnulib-tool' will create a separate directory with its own 'POTFILES.in', and fetch current translations directly from the Translation Project (using 'rsync' or 'wget', whichever is available). The POT file in this directory will be called 'DOMAIN-gnulib.pot', depending on the DOMAIN you gave to the '--po-domain' option (typically the same as the package name). This causes these translations to reside in a separate message domain, so that they do not clash either with the translations for the main part of your package nor with those of other packages on the system that use possibly different versions of Gnulib. When you use these options, the functions in Gnulib are built in such a way that they will always use this domain regardless of the default domain set by 'textdomain'. In order to use this method, you must--in each program that might use Gnulib code--add an extra line to the part of the program that initializes locale-dependent behavior. Where you would normally write something like: setlocale (LC_ALL, ""); bindtextdomain (PACKAGE, LOCALEDIR); textdomain (PACKAGE); you should add an additional 'bindtextdomain' call to inform gettext of where the MO files for the extra message domain may be found: bindtextdomain (PACKAGE "-gnulib", LOCALEDIR); (This example assumes that the DOMAIN that you specified to 'gnulib-tool' is the same as the value of the 'PACKAGE' preprocessor macro.) Since you do not change the 'textdomain' call, the default message domain for your program remains the same and your own use of 'gettext' functions will not be affected. 3.9 Issues with Version Control Systems ======================================= If a project stores its source files in a version control system (VCS), such as CVS, Subversion, or Git, one needs to decide which files to commit. In principle, all files created by 'gnulib-tool', except 'gnulib-cache.m4', can be treated like generated source files, like for example a 'parser.c' file generated from 'parser.y'. Alternatively, they can be considered source files and updated manually. Here are the three different approaches in common use. Each has its place, and you should use whichever best suits your particular project and development methods. 1. In projects which commit all source files, whether generated or not, into their VCS, the 'gnulib-tool' generated files should all be committed. In this case, you should pass the option '--no-vc-files' to 'gnulib-tool', which avoids alteration of VCS-related files such as '.gitignore'. Gnulib also contains files generated by 'make' (and removed by 'make clean'), using information determined by 'configure'. For a Gnulib source file of the form 'lib/foo.in.h', the corresponding 'lib/foo.h' is such a 'make'-generated file. These should _not_ be checked into the VCS, but instead added to '.gitignore' or equivalent. 2. In projects which customarily omit from their VCS all files that are generated from other source files, none of these files and directories are added into the VCS. As described in *note Modified imports::, there are two ways to keep track of options and module names that are passed to 'gnulib-tool'. The command for restoring the omitted files depends on it: * If they are stored in a file other than 'gnulib-cache.m4', such as 'autogen.sh', 'bootstrap', 'bootstrap.conf', or similar, the restoration command is the entire 'gnulib-tool ... --import ...' invocation with all options and module names. * If the project relies on 'gnulib-tool''s memory of the last used options and module names, then the file 'gnulib-cache.m4' in the M4 macros directory must be added to the VCS, and the restoration command is: $ gnulib-tool --update The '--update' option operates much like the '--add-import' option, but it does not offer the possibility to change the way Gnulib is used. Also it does not report in the ChangeLogs the files that it had to add because they were missing. Gnulib includes the file 'build-aux/bootstrap' to aid a developer in using this setup. Furthermore, in projects that use git for version control, it is possible to use a git submodule containing the precise commit of the gnulib repository, so that each developer running 'bootstrap' will get the same version of all gnulib-provided files. The location of the submodule can be chosen to fit the package's needs; here's how to initially create the submodule in the directory '.gnulib': $ dir=.gnulib $ git submodule add -- git://git.sv.gnu.org/gnulib.git $dir $ git config alias.syncsub "submodule foreach git pull origin master" Thereafter, 'bootstrap' can run this command to update the submodule to the recorded checkout level: git submodule update --init $dir and a developer can use this sequence to update to a newer version of gnulib: $ git syncsub $ git add $dir $ ./bootstrap 3. Some projects take a "middle road": they do commit Gnulib source files as in the first approach, but they do not commit other derived files, such as a 'Makefile.in' generated by Automake. This increases the size and complexity of the repository, but can help occasional contributors by not requiring them to have a full Gnulib checkout to do a build, and all developers by ensuring that all developers are working with the same version of Gnulib in the repository. It also supports multiple Gnulib instances within a project. It remains important not to commit the 'make'-generated files, as described above. 3.10 Bundling the unit tests of the Gnulib modules ================================================== You can bundle the unit tests of the Gnulib modules together with your package, through the '--with-tests' option. Together with '--with-tests', you also specify the directory for these tests through the '--tests-base' option. Of course, you need to add this directory to the 'SUBDIRS' variable in the 'Makefile.am' of the parent directory. The advantage of having the unit tests bundled is that when your program has a problem on a particular platform, running the unit tests may help determine quickly if the problem is on Gnulib's side or on your package's side. Also, it helps verifying Gnulib's portability, of course. The unit tests will be compiled and run when the user runs 'make check'. When the user runs only 'make', the unit tests will not be compiled. In the 'SUBDIRS' variable, it is useful to put the Gnulib tests directory after the directory containing the other tests, not before: SUBDIRS = gnulib-lib src man tests gnulib-tests This will ensure that on platforms where there are test failures in either directory, users will see and report the failures from the tests of your program. Note: In packages which use more than one invocation of 'gnulib-tool' in the scope of the same 'configure.ac', you cannot use '--with-tests'. You will have to use a separate 'configure.ac' in this case. 3.11 Avoiding unnecessary checks and compilations ================================================= In some cases, a module is needed by another module only on specific platforms. But when a module is present, its autoconf checks are always executed, and its 'Makefile.am' additions are always enabled. So it can happen that some autoconf checks are executed and some source files are compiled, although no other module needs them on this particular platform, just _in case_ some other module would need them. The option '--conditional-dependencies' enables an optimization of configure checks and 'Makefile.am' snippets that avoids this. With this option, whether a module is considered "present" is no longer decided when 'gnulib-tool' is invoked, but later, when 'configure' is run. This applies to modules that were added as dependencies while 'gnulib-tool' was run; modules that were passed on the command line explicitly are always "present". For example, the 'timegm' module needs, on platforms where the system's 'timegm' function is missing or buggy, a replacement that is based on a function 'mktime_internal'. The module 'mktime-internal' that provides this function provides it on all platforms. So, by default, the file 'mktime-internal.c' will be compiled on all platforms, even on glibc and BSD systems which have a working 'timegm' function. When the option '--conditional-dependencies' is given, on the other hand, and if 'mktime-internal' was not explicitly required on the command line, the file 'mktime-internal.c' will only be compiled on the platforms where the 'timegm' needs them. Conditional dependencies are specified in the module description by putting the condition on the same line as the dependent module, enclosed in brackets. The condition is a boolean shell expression that can assume that the 'configure.ac' snippet from the module description has already been executed. In the example above, the dependency from 'timegm' to 'mktime-internal' is written like this: Depends-on: ... mktime-internal [test $HAVE_TIMEGM = 0 || test $REPLACE_TIMEGM = 1] ... Note: The option '--conditional-dependencies' cannot be used together with the option '--with-tests'. It also cannot be used when a package uses 'gnulib-tool' for several subdirectories, with different values of '--source-base', in the scope of a single 'configure.ac' file. 4 Writing modules ***************** This chapter explains how to write modules of your own, either to extend Gnulib for your own package (*note Extending Gnulib::), or for inclusion in gnulib proper. The guidelines in this chapter do not necessarily need to be followed for using 'gnulib-tool'. They merely represent a set of good practices. Following them will result in a good structure of your modules and in consistency with gnulib. 4.1 Source code files ===================== Every API (C functions or variables) provided should be declared in a header file (.h file) and implemented in one or more implementation files (.c files). The separation has the effect that users of your module need to read only the contents of the .h file and the module description in order to understand what the module is about and how to use it--not the entire implementation. Furthermore, users of your module don't need to repeat the declarations of the functions in their code, and are likely to receive notification through compiler errors if you make incompatible changes to the API (like, adding a parameter or changing the return type of a function). 4.2 Header files ================ The .h file should declare the C functions and variables that the module provides. The .h file should be stand-alone. That is, it does not require other .h files to be included before. Rather, it includes all necessary .h files by itself. It is a tradition to use CPP tricks to avoid parsing the same header file more than once, which might cause warnings. The trick is to wrap the content of the header file (say, 'foo.h') in a block, as in: #ifndef FOO_H # define FOO_H ... body of header file goes here ... #endif /* FOO_H */ Whether to use 'FOO_H' or '_FOO_H' is a matter of taste and style. The C89 and C99 standards reserve all identifiers that begin with an underscore and either an uppercase letter or another underscore, for any use. Thus, in theory, an application might not safely assume that '_FOO_H' has not already been defined by a library. On the other hand, using 'FOO_H' will likely lead the higher risk of collisions with other symbols (e.g., 'KEY_H', 'XK_H', 'BPF_H', which are CPP macro constants, or 'COFF_LONG_H', which is a CPP macro function). Your preference may depend on whether you consider the header file under discussion as part of the application (which has its own namespace for CPP symbols) or a supporting library (that shouldn't interfere with the application's CPP symbol namespace). Adapting C header files for use in C++ applications can use another CPP trick, as in: # ifdef __cplusplus extern "C" { # endif ... body of header file goes here ... # ifdef __cplusplus } # endif The idea here is that '__cplusplus' is defined only by C++ implementations, which will wrap the header file in an 'extern "C"' block. Again, whether to use this trick is a matter of taste and style. While the above can be seen as harmless, it could be argued that the header file is written in C, and any C++ application using it should explicitly use the 'extern "C"' block itself. Your preference might depend on whether you consider the API exported by your header file as something available for C programs only, or for C and C++ programs alike. Note that putting a '#include' in an 'extern "C" { ... }' block yields a syntax error in C++ mode on some platforms (e.g., glibc systems with g++ v3.3 to v4.2, AIX, OSF/1, IRIX). For this reason, it is recommended to place the '#include' before the 'extern "C"' block. 4.3 Implementation files ======================== The .c file or files implement the functions and variables declared in the .h file. Include ordering ---------------- Every implementation file must start with '#include '. This is necessary for activating the preprocessor macros that are defined on behalf of the Autoconf macros. Some of these preprocessor macros, such as '_GNU_SOURCE', would have no effect if defined after a system header file has already been included. Then comes the '#include "..."' specifying the header file that is being implemented. Putting this right after '#include ' has the effect that it verifies that the header file is self-contained. Then come the system and application headers. It is customary to put all the system headers before all application headers, so as to minimize the risk that a preprocessor macro defined in an application header confuses the system headers on some platforms. In summary: * First comes #include . * Second comes the #include "..." specifying the module being implemented. * Then come all the #include <...> of system or system-replacement headers, in arbitrary order. * Then come all the #include "..." of gnulib and application headers, in arbitrary order. 4.4 Specification ================= The specification of a function should answer at least the following questions: * What is the purpose of the function? * What are the arguments? * What is the return value? * What happens in case of failure? (Exit? A specific return value? Errno set?) * Memory allocation policy: If pointers to memory are returned, are they freshly allocated and supposed to be freed by the caller? Where to put the specification describing exported functions? Three practices are used in gnulib: * The specification can be as comments in the header file, just above the function declaration. * The specification can be as comments in the implementation file, just above the function definition. * The specification can be in texinfo format, so that it gets included in the gnulib manual. In any case, the specification should appear in just one place, unless you can ensure that the multiple copies will always remain identical. The advantage of putting it in the header file is that the user only has to read the include file normally never needs to peek into the implementation file(s). The advantage of putting it in the implementation file is that when reviewing or changing the implementation, you have both elements side by side. The advantage of texinfo formatted documentation is that it is easily published in HTML or Info format. Currently (as of 2010), half of gnulib uses the first practice, nearly half of gnulib uses the second practice, and a small minority uses the texinfo practice. 4.5 Module description ====================== For the module description, you can start from an existing module's description, or from a blank one: 'module/TEMPLATE' for a normal module, or 'module/TEMPLATE-TESTS' for a unit test module. Some more fields are possible but rarely used. Use 'module/TEMPLATE-EXTENDED' if you want to use one of them. Module descriptions have the following fields. Absent fields are equivalent to fields with empty contents. Description This field should contain a concise description of the module's functionality. One sentence is enough. For example, if it defines a single function 'frob', the description can be 'frob() function: frobnication.' Gnulib's documentation generator will automatically convert the first part to a hyperlink when it has this form. Status This field is either empty/absent, or contains the word 'obsolete'. In the latter case, 'gnulib-tool' will, unless the option '--with-obsolete' is given, omit it when it used as a dependency. It is good practice to also notify the user about an obsolete module. This is done by putting into the 'Notice' section (see below) text like 'This module is obsolete.' Notice This field contains text that 'gnulib-tool' will show to the user when the module is used. This can be a status indicator like 'This module is obsolete.' or additional advice. Do not abuse this field. Applicability This field is either empty/absent, or contains the word 'all'. It describes to which 'Makefile.am' the module is applied. By default, a normal module is applied to 'SOURCE_BASE/Makefile.am' (normally 'lib/Makefile.am'), whereas a module ending in '-tests' is applied to 'TESTS_BASE/Makefile.am' (normally 'tests/Makefile.am'). If this field is 'all', it is applied to both 'Makefile.am's. This is useful for modules which provide Makefile.am macros rather than compiled source code. Files This field contains a newline separated list of the files that are part of the module. 'gnulib-tool' copies these files into the package that uses the module. This list is typically ordered by importance: First comes the header file, then the implementation files, then other files. It is possible to have the same file mentioned in multiple modules. That is, if the maintainers of that module agree on the purpose and future of said file. Depends-on This field contains a newline separated list of the modules that are required for the proper working of this module. 'gnulib-tool' includes each required module automatically, unless it is specified with option '--avoid' or it is marked as obsolete and the option '--with-obsolete' is not given. A test modules 'foo-tests' implicitly depends on the corresponding non-test module 'foo'. 'foo' implicitly depends on 'foo-tests' if the latter exists and if the option '--with-tests' has been given. Tests modules can depend on non-tests modules. Non-tests modules should not depend on tests modules. (Recall that tests modules are built in a separate directory.) Each listed required module may be declared a conditional dependency. This is indicated by placing the condition for the dependency on the same line, enclosed in brackets, after the name of the required module. The condition is a shell expression that is run after the module's 'configure.ac' statements. For example: strtoull [test $ac_cv_func_strtoumax = no] Lines starting with '#' are recognized as comments and are ignored. configure.ac-early This field contains 'configure.ac' stuff (Autoconf macro invocations and shell statements) that are logically placed early in the 'configure.ac' file: right after the 'AC_PROG_CC' invocation. This section is adequate for statements that modify 'CPPFLAGS', as these can affect the results of other Autoconf macros. configure.ac This field contains 'configure.ac' stuff (Autoconf macro invocations and shell statements). It is forbidden to add items to the 'CPPFLAGS' variable here, other than temporarily, as these could affect the results of other Autoconf macros. We avoid adding items to the 'LIBS' variable, other than temporarily. Instead, the module can export an Autoconf-substituted variable that contains link options. The user of the module can then decide to which executables to apply which link options. Recall that a package can build executables of different kinds and purposes; having all executables link against all libraries is inappropriate. If the statements in this section grow larger than a couple of lines, we recommend moving them to a '.m4' file of their own. Makefile.am This field contains 'Makefile.am' statements. Variables like 'lib_SOURCES' are transformed to match the name of the library being built in that directory. For example, 'lib_SOURCES' may become 'libgnu_a_SOURCES' (for a plain library) or 'libgnu_la_SOURCES' (for a libtool library). Therefore, the normal way of having an implementation file 'lib/foo.c' compiled unconditionally is to write lib_SOURCES += foo.c Include This field contains the preprocessor statements that users of the module need to add to their source code files. Typically it's a single include statement. A shorthand is allowed: You don't need to write the word "#include", just the name of the include file in the way it will appear in an include statement. Example: "foo.h" Link This field contains the set of libraries that are needed when linking libraries or executables that use this module. Often this will be written as a reference to a Makefile variable. Please write them one per line, so that 'gnulib-tool' can remove duplicates when presenting a summary to the user. Example: $(POW_LIBM) $(LTLIBICONV) when linking with libtool, $(LIBICONV) otherwise License This field specifies the license that governs the source code parts of this module. See *note Copyright:: for details. Maintainer This field specifies the persons who have a definitive say about proposed changes to this module. You don't need to mention email addresses here: they can be inferred from the 'ChangeLog' file. Please put at least one person here. We don't like unmaintained modules. 4.6 Autoconf macros =================== For a module 'foo', an Autoconf macro file 'm4/foo.m4' is typically created when the Autoconf macro invocations for the module are longer than one or two lines. The name of the main entry point into this Autoconf macro file is typically 'gl_FOO'. For modules outside Gnulib that are not likely to be moved into Gnulib, please use a prefix specific to your package: 'gt_' for GNU gettext, 'cu_' for GNU coreutils, etc. For modules that define a function 'foo', the entry point is called 'gl_FUNC_FOO' instead of 'gl_FOO'. For modules that provide a header file with multiple functions, say 'foo.h', the entry point is called 'gl_FOO_H' or 'gl_HEADER_FOO_H'. This convention is useful because sometimes a header and a function name coincide (for example, 'fcntl' and 'fcntl.h'). For modules that provide a replacement, it is useful to split the Autoconf macro into two macro definitions: one that detects whether the replacement is needed and requests the replacement using 'AC_LIBOBJ' (this is the entry point, say 'gl_FUNC_FOO'), and one that arranges for the macros needed by the replacement code 'lib/foo.c' (typically called 'gl_PREREQ_FOO'). The reason of this separation is 1. to make it easy to update the Autoconf macros when you have modified the source code file: after changing 'lib/foo.c', all you have to review is the 'Depends-on' section of the module description and the 'gl_PREREQ_FOO' macro in the Autoconf macro file. 2. The Autoconf macros are often large enough that splitting them eases maintenance. 4.7 Unit test modules ===================== A unit test that is a simple C program usually has a module description as simple as this: Files: tests/test-foo.c tests/macros.h Depends-on: configure.ac: Makefile.am: TESTS += test-foo check_PROGRAMS += test-foo The test program 'tests/test-foo.c' often has the following structure: * First comes the obligatory '#include '. * Second comes the include of the header file that declares the API being tested. Including it here verifies that said header file is self-contained. * Then come other includes. In particular, the file 'macros.h' is often used here. It contains a convenient 'ASSERT' macro. The body of the test, then, contains many 'ASSERT' invocations. When a test fails, the 'ASSERT' macro prints the line number of the failing statement, thus giving you, the developer, an idea of which part of the test failed, even when you don't have access to the machine where the test failed and the reporting user cannot run a debugger. Sometimes it is convenient to write part of the test as a shell script. (For example, in areas related to process control or interprocess communication, or when different locales should be tried.) In these cases, the typical module description is like this: Files: tests/test-foo.sh tests/test-foo.c tests/macros.h Depends-on: configure.ac: Makefile.am: TESTS += test-foo.sh TESTS_ENVIRONMENT += FOO_BAR='@FOO_BAR@' check_PROGRAMS += test-foo Here, the 'TESTS_ENVIRONMENT' variable can be used to pass values determined by 'configure' or by the 'Makefile' to the shell script, as environment variables. The values of 'EXEEXT' and of 'srcdir', from Autoconf and Automake, are already provided as environment variables, through an initial value of 'TESTS_ENVIRONMENT' that 'gnulib-tool' puts in place. Regardless of the specific form of the unit test, the following guidelines should be respected: * A test indicates success by exiting with exit code 0. It should normally not produce output in this case. (Output to temporary files that are cleaned up at the end of the test are possible, of course.) * A test indicates failure by exiting with an exit code different from 0 and 77, typically 1. It is useful to print a message about the failure in this case. The 'ASSERT' macro already does so. * A test indicates "skip", that is, that most of its interesting functionality could not be performed, through a return code of 77. A test should also print a message to stdout or stderr about the reason for skipping. For example: fputs ("Skipping test: multithreading not enabled\n", stderr); return 77; Such a message helps detecting bugs in the autoconf macros: A simple message 'SKIP: test-foo' does not sufficiently catch the attention of the user. 4.8 Incompatible changes ======================== Incompatible changes to Gnulib modules should be mentioned in Gnulib's 'NEWS' file. Incompatible changes here mean that existing source code may not compile or work any more. We don't mean changes in the binary interface (ABI), since 1. Gnulib code is used in source-code form. 2. The user who distributes libraries that contain Gnulib code is supposed to bump the version number in the way described in the Libtool documentation before every release. 5 Extending Gnulib ****************** Gnulib modules are intended to be suitable for widespread use. Most problems with Gnulib can and should be fixed in a generic way, so that all of Gnulib's users can benefit from the change. But occasionally a problem arises that is difficult or undesirable to fix generically, or a project that uses Gnulib may need to work around an issue before the Gnulib maintainers commit a final fix. Maintainers may also want to add their own pools of modules to projects as Gnulib "staging areas." The obvious way to make local changes to Gnulib modules is to use 'gnulib-tool' to check out pristine modules, then to modify the results in-place. This works well enough for short-lived experiments. It is harder to keep modified versions of Gnulib modules for a long time, even though Git (or another distributed version control systems) can help out a lot with this during the development process. Git, however, doesn't address the distribution issue. When a package "foobar" needs a modified version of, say, 'stdint.in.h', it either has to put a comment into 'foobar/autogen.sh' saying "Attention! This doesn't work with a pristine Gnulib, you need this and that patch after checking out Gnulib," or it has to use the '--avoid=stdint' option and provide the modified 'stdint' module in a different directory. The '--local-dir' option to 'gnulib-tool' solves this problem. It allows the package to override or augment Gnulib. This means: * You can store files that are to override Gnulib files or modules. * You can store context diffs to be applied to Gnulib files. * You can add modules of your own, that are not (yet) in Gnulib. * You can also add unstructured amounts of code to the library, by grouping the non-Gnulib files of the library in a single kitchen-sink "module." (This kind of kitchen-sink module is not needed when you use the 'gnulib-tool' option '--makefile-name'.) In a release tarball, you can distribute the contents of this '--local-dir' directory that will be combinable with newer versions of Gnulib, barring incompatible changes to Gnulib. If the '--local-dir=DIRECTORY' option is specified, then 'gnulib-tool' looks in 'DIRECTORY' whenever it reads a file from the Gnulib directory. Suppose 'gnulib-tool' is looking for FILE. Then: * If 'DIRECTORY/FILE' exists, then 'gnulib-tool' uses it instead of the file included in Gnulib. * Otherwise, if 'DIRECTORY/FILE.diff' exists, then 'gnulib-tool' uses the file from Gnulib after applying the diff using the 'patch' program. * Otherwise, 'gnulib-tool' uses the file included in Gnulib. Please make wise use of this option. It also allows you to easily hold back modifications you make to Gnulib macros in cases it may be better to share them. 6 Miscellaneous Notes ********************* 6.1 Out of memory handling ========================== The gnulib API does not have a standard error code for the out of memory error condition. Instead of adding a non-standard error code, gnulib has chosen to adopt a different strategy. Out of memory handling happens in rare situations, but performing the out of memory error handling after almost all API function invocations pollute your source code and might make it harder to spot more serious problems. The strategy chosen improves code readability and robustness. For most applications, aborting the application with an error message when the out of memory situation occurs is the best that can be wished for. This is how the library behaves by default (using the 'xalloc-die' module). However, we realize that some applications may not want to abort execution in any situation. Gnulib supports a hook to let the application regain control and perform its own cleanups when an out of memory situation has occurred. The application can define a function (having a 'void' prototype, i.e., no return value and no parameters) and set the library variable 'xalloc_die' to that function. The variable should be declared as follows. extern void (*xalloc_die) (void); Gnulib will invoke this function if an out of memory error occurs. Note that the function should not return. Of course, care must be taken to not allocate more memory, as that will likely also fail. 6.2 Obsolete modules ==================== Modules can be marked obsolete. This means that the problems they fix don't occur any more on the platforms that are reasonable porting targets now. 'gnulib-tool' warns when obsolete modules are mentioned on the command line, and by default ignores dependencies from modules to obsolete modules. When you pass the option '--with-obsolete' to 'gnulib-tool', dependencies to obsolete modules will be included, however, unless blocked through an '--avoid' option. This option is useful if your package should be portable even to very old platforms. In order to mark a module obsolete, you need to add this to the module description: Status: obsolete Notice: This module is obsolete. 6.3 Extra tests modules ======================= Test modules can be marked with some special status attributes. When a test module has such an attribute, 'gnulib-tool --import' will not include it by default. The supported status attributes are: 'c++-test' Indicates that the test is testing C++ interoperability. Such a test is useful in a C++ or mixed C/C++ package, but is useless in a C package. 'longrunning-test' Indicates that the test takes a long time to compile or execute (more than five minutes or so). Such a test is better avoided in a release that is made for the general public. 'privileged-test' Indicates that the test will request special privileges, for example, ask for the superuser password. Such a test may hang when run non-interactively and is therefore better avoided in a release that is made for the general public. 'unportable-test' Indicates that the test is known to fail on some systems, and that there is no workaround about it. Such a test is better avoided in a release that is made for the general public. 'gnulib-tool --import --with-tests' will not include tests marked with these attributes by default. When 'gnulib-tool' is invoked with one of the options '--with-c++-tests', '--with-longrunning-tests', '--with-privileged-tests', '--with-unportable-tests', it will include tests despite the corresponding special status attribute. When 'gnulib-tool' receives the option '--with-all-tests', it will include all tests regardless of their status attributes. 'gnulib-tool --create-testdir --with-tests' and 'gnulib-tool --create-megatestdir --with-tests' by default include all tests of modules specified on the command line, regardless of their status attributes. Tests of modules occurring as dependencies are not included by default if they have one of these status attributes. The options '--with-c++-tests', '--with-longrunning-tests', '--with-privileged-tests', '--with-unportable-tests' are recognized here as well. Additionally, 'gnulib-tool' also understands the options '--without-c++-tests', '--without-longrunning-tests', '--without-privileged-tests', '--without-unportable-tests'. In order to mark a module with a status attribute, you need to add it to the module description, like this: Status: longrunning-test If only a part of a test deserves a particular status attribute, you can split the module into a primary and a secondary test module, say 'foo-tests' and 'foo-extra-tests'. Then add a dependency from 'foo-tests' to 'foo-extra-tests', and mark the 'foo-extra-tests' with the particular status attribute. 6.4 A C++ namespace for gnulib ============================== The function definitions provided by Gnulib ('.c' code) are meant to be compiled by a C compiler. The header files ('.h' files), on the other hand, can be used in either C or C++. By default, when used in a C++ compilation unit, the '.h' files declare the same symbols and overrides as in C mode, except that functions defined by Gnulib or by the system are declared as 'extern "C"'. It is also possible to indicate to Gnulib to provide many of its symbols in a dedicated C++ namespace. If you define the macro 'GNULIB_NAMESPACE' to an identifier, many functions will be defined in the namespace specified by the identifier instead of the global namespace. For example, after you have defined #define GNULIB_NAMESPACE gnulib at the beginning of a compilation unit, Gnulib's '' header file will make available the 'open' function as 'gnulib::open'. The symbol 'open' will still refer to the system's 'open' function, with its platform specific bugs and limitations. The symbols provided in the Gnulib namespace are those for which the corresponding header file contains a '_GL_CXXALIAS_RPL' or '_GL_CXXALIAS_SYS' macro invocation. The benefits of this namespace mode are: * Gnulib defines fewer symbols as preprocessor macros. For example, on a platform where 'open' has to be overridden, Gnulib normally does '#define open rpl_open'. If your package has a class with a member 'open', for example a class 'foo' with a method 'foo::open', then if you define this member in a compilation unit that includes '' and use it in a compilation unit that does not include '', or vice versa, you will get a link error. Worse: You will not notice this problem on the platform where the system's 'open' function works fine. This problem goes away in namespace mode. * It provides a safety check whether the set of modules your package requests from Gnulib is sufficient. For example, if you use the function 'gnulib::open' in your code, and you forgot to request the module 'open' from Gnulib, you will get a compilation error (regardless of the platform). The drawback of this namespace mode is that the system provided symbols in the global namespace are still present, even when they contain bugs that Gnulib fixes. For example, if you call 'open (...)' in your code, it will invoke the possibly buggy system function, even if you have requested the module 'open' from gnulib-tool. You can turn on the namespace mode in some compilation units and keep it turned off in others. This can be useful if your package consists of an application layer that does not need to invoke POSIX functions and an operating system interface layer that contains all the OS function calls. In such a situation, you will want to turn on the namespace mode for the application layer--to avoid many preprocessor macro definitions--and turn it off for the OS interface layer--to avoid the drawback of the namespace mode, mentioned above. 6.5 Library version handling ============================ The module 'check-version' can be useful when your gnulib application is a system library. You will typically wrap the call to the 'check_version' function through a library API, your library header file may contain: #define STRINGPREP_VERSION "0.5.18" ... extern const char *stringprep_check_version (const char *req_version); To avoid ELF symbol collisions with other libraries that use the 'check-version' module, add to 'config.h' through a AC_DEFINE something like: AC_DEFINE(check_version, stringprep_check_version, [Rename check_version.]) The 'stringprep_check_version' function will thus be implemented by the 'check_version' module. There are two uses of the interface. The first is a way to provide for applications to find out the version number of the library it uses. The application may contain diagnostic code such as: printf ("Stringprep version: header %s library %s", STRINGPREP_VERSION, stringprep_check_version (NULL)); Separating the library and header file version can be useful when searching for version mismatch related problems. The second uses is as a rudimentary test of proper library version, by making sure the application get a library version that is the same, or newer, than the header file used when building the application. This doesn't catch all problems, libraries may change backwards incompatibly in later versions, but enable applications to require a certain minimum version before it may proceed. Typical uses look like: /* Check version of libgcrypt. */ if (!gcry_check_version (GCRYPT_VERSION)) die ("version mismatch\n"); 6.6 Windows sockets =================== There are several issues when building applications that should work under Windows. The most problematic part is for applications that use sockets. Hopefully, we can add helpful notes to this section that will help you port your application to Windows using gnulib. 6.6.1 Getaddrinfo and WINVER ---------------------------- This was written for the getaddrinfo module, but may be applicable to other functions too. The getaddrinfo function exists in ws2tcpip.h and -lws2_32 on Windows XP. The function declaration is present if 'WINVER >= 0x0501'. Windows 2000 does not have getaddrinfo in its 'WS2_32.DLL'. Thus, if you want to assume Windows XP or later, you can add AC_DEFINE(WINVER, 0x0501) to avoid compiling the (partial) getaddrinfo implementation. If you want to support Windows 2000, don't do anything. The replacement function will open 'WS2_32.DLL' during run-time to see if there is a getaddrinfo function available, and use it when available. 6.7 Libtool and Windows ======================= If you want it to be possible to cross-compile your program to MinGW and you use Libtool, you need to put: AC_LIBTOOL_WIN32_DLL in your 'configure.ac'. This sets the correct names for the 'OBJDUMP', 'DLLTOOL', and 'AS' tools for the build. If you are building a library, you will also need to pass '-no-undefined' to make sure Libtool produces a DLL for your library. From a 'Makefile.am': libgsasl_la_LDFLAGS += -no-undefined 6.8 License Texinfo sources =========================== Gnulib provides copies of the GNU GPL, GNU LGPL, and GNU FDL licenses in Texinfo form. (The master location is ). These Texinfo documents do not have any node names and structures built into them; for your manual, you should '@include' them in an appropriate '@node'. The conventional name for the GPL node is 'Copying' and for the FDL 'GNU Free Documentation License'. The LGPL doesn't seem to have a conventional node name. Of course the license texts themselves should not be changed at all. 6.9 Build robot for gnulib ========================== To simplify testing on a wide set of platforms, gnulib is built on many platforms every day and the results are uploaded to: If you wish to help the gnulib development effort with build logs for your favorite platform, you may perform these steps: 1. Create gnulib directory On a machine with recent automake, autoconf, m4 installed and with a gnulib git checkout (typically a Linux machine), use gnulib-tool --create-megatestdir --with-tests --dir=... Note: The created directory uses ca. 512 MB on disk. 2. Transfer gnulib directory Transfer this directory to a build machine (HP-UX, Cygwin, or whatever). Often it is easier to transfer one file, and this can be achieved by running, inside the directory the following commands: ./configure make dist And then transferring the 'dummy-0.tar.gz' file. 3. Build modules On the build machine, run ./do-autobuild (or "nohup ./do-autobuild"). It creates a directory 'logs/' with a log file for each module. 4. Submit build logs Submit each log file to Simon's site, either through a mail `echo gnulib__at__autobuild.josefsson.org | sed -e s/__at__/@/` or through netcat autobuild-submit logs/* 7 Building the ISO C and POSIX Substitutes ****************************************** This section shows a radically different way to use Gnulib. You can extract the ISO C / POSIX substitutes part of gnulib by running the command gnulib-tool --create-testdir --source-base=lib \ --dir=/tmp/posixlib `posix-modules` The command 'posix-modules' is found in the same directory as 'gnulib-tool'. The resulting directory can be built on a particular platform, independently of the program being ported. Then you can configure and build any program, by setting 'CPPFLAGS' and 'LDFLAGS' at configure time accordingly: set 'CPPFLAGS="-I.../posixlib/lib"', plus any essential type definitions and flags that you find in '.../posixlib/config.h', and set 'LDFLAGS=".../posixlib/lib/libgnu.a"'. This way of using Gnulib is useful when you don't want to modify the program's source code, or when the program uses a mix between C and C++ sources (requiring separate builds of the 'posixlib' for the C compiler and for the C++ compiler). 8 ISO C and POSIX Header File Substitutes ***************************************** This chapter describes which header files specified by ISO C or POSIX are substituted by Gnulib, which portability pitfalls are fixed by Gnulib, and which (known) portability problems are not worked around by Gnulib. The notation "Gnulib module: --" means that Gnulib does not provide a module providing a substitute for the header file. When the list "Portability problems not fixed by Gnulib" is empty, such a module is not needed: No portability problems are known. Otherwise, it indicates that such a module would be useful but is not available: No one so far found this header file important enough to contribute a substitute for it. If you need this particular header file, you may write to ''. 8.1 'aio.h' =========== POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This header file is missing on some platforms: Mac OS X 10.3, NetBSD 3.0, OpenBSD 3.8, Minix 3.1.8, Cygwin, mingw, MSVC 9, Interix 3.5, BeOS. 8.2 'arpa/inet.h' ================= POSIX specification: Gnulib module: arpa_inet Portability problems fixed by Gnulib: * This header file is missing on some platforms: mingw, MSVC 9, BeOS. Portability problems not fixed by Gnulib: 8.3 'assert.h' ============== POSIX specification: Gnulib module: assert-h See also the Gnulib module 'assert'. Portability problems fixed by Gnulib: * The C11 and C++11 'static_assert', and the C11 '_Static_assert', are not supported by many platforms. For example, GCC versions before 4.6.0 do not support '_Static_assert', and G++ versions through at least 4.6.0 do not support 'static_assert'. Portability problems not fixed by Gnulib: * C11 '_Static_assert' and C++11 'static_assert' are keywords that can be used without including ''. The Gnulib substitutes are macros that require including ''. * The C11 'static_assert' and '_Static_assert' can also be used within a 'struct' or 'union' specifier, in place of an ordinary declaration of a member of the struct or union. The Gnulib substitute can be used only as an ordinary declaration. * In C99, 'assert' can be applied to any scalar expression. In C89, the argument to 'assert' is of type 'int'. 8.4 'complex.h' =============== POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This header file is missing on some platforms: NetBSD 3.0, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Cygwin 1.7.7, mingw, MSVC 9, Interix 3.5, BeOS. 8.5 'cpio.h' ============ POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This header file is missing on some platforms: Mac OS X 10.3, Minix 3.1.8, Cygwin, mingw, MSVC 9, BeOS. 8.6 'ctype.h' ============= POSIX specification: Gnulib module: ctype Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: 8.7 'dirent.h' ============== POSIX specification: Gnulib module: dirent Portability problems fixed by Gnulib: * The type 'ino_t' is missing on some platforms: glibc 2.8 and others.

Portability problems not fixed by Gnulib: 8.10 'fcntl.h' ============== POSIX specification: Gnulib module: fcntl-h Portability problems fixed by Gnulib: * The type 'pid_t' is not defined on some platforms: MSVC 9. * The type 'mode_t' is not defined on some platforms: MSVC 9. * 'O_CLOEXEC', 'O_DIRECTORY', 'O_DSYNC', 'O_NOCTTY', 'O_NOFOLLOW', 'O_RSYNC', 'O_SYNC', and 'O_TTY_INIT' are not defined on some platforms. Gnulib defines these macros to 0, which is generally safe. * 'O_NONBLOCK' is not defined on some platforms.

This compiler bug causes the Gnulib module 'stdalign-tests' to fail. The Sun Studio Developer Bug Report Review Team assigned the internal review ID 2125432 (dated 2011-11-01) to this issue. * '' must be #included before '_Alignas' and '_Alignof' can be used. * You cannot assume that '_Alignas' and '_Alignof' are reserved words; they might be macros. 8.45 'stdarg.h' =============== POSIX specification: Gnulib module: stdarg Portability problems fixed by Gnulib: * Some compilers (e.g., AIX 5.3 cc) need to be in c99 mode for the builtin 'va_copy' to work.

Portability problems not fixed by Gnulib: * '{uint,int}_fast{8,16,32,64}_t' may not correspond to the fastest types available on the system. Other '' substitutes may define these types differently, so public header files should avoid these types. * Macros are used instead of typedefs. * Some C preprocessors mishandle constants that do not fit in 'long int'. For example, as of 2007, Sun C mishandles '#if LLONG_MIN < 0' on a platform with 32-bit 'long int' and 64-bit 'long long int'. Some older preprocessors mishandle constants ending in 'LL'. To work around these problems, compute the value of expressions like 'LONG_MAX < LLONG_MAX' at 'configure'-time rather than at '#if'-time. The stdint.h module uses '#include_next'.

Although the resulting code operates correctly, the compiler is not informed whether 'noreturn' functions do not return, so it may generate incorrect warnings at compile-time, or code that is slightly less optimized. This problem does not occur with '_Noreturn'. * Circa 2012 bleeding-edge GCC with '-Werror=old-style-declaration' requires '_Noreturn' or 'noreturn' before the returned type in a declaration, and therefore rejects valid but unusually-worded declarations such as 'void _Noreturn foo (void);'. 8.52 'string.h' =============== POSIX specification: Gnulib module: string Portability problems fixed by Gnulib: * Some platforms provide a 'NULL' macro that cannot be used in arbitrary expressions: NetBSD 5.0 Portability problems not fixed by Gnulib: 8.53 'strings.h' ================ POSIX specification: Gnulib module: strings Portability problems fixed by Gnulib: * This header file is not self-contained on some platforms: Minix 3.1.8. Portability problems not fixed by Gnulib: * This header file is missing on some platforms: MSVC 9. * This header file defines symbols, such as 'index', often used for variables, making debugging harder. 8.54 'stropts.h' ================ POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This header file is missing on some platforms: Mac OS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8, Cygwin, mingw, MSVC 9, BeOS. 8.55 'sys/ipc.h' ================ POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This header file is missing on some platforms: mingw, MSVC 9, BeOS. 8.56 'sys/mman.h' ================= POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This header file is missing on some platforms: mingw, MSVC 9, BeOS. 8.57 'sys/msg.h' ================ POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This header file is missing on some platforms: Mac OS X 10.3, Minix 3.1.8, mingw, MSVC 9, BeOS. 8.58 'sys/resource.h' ===================== POSIX specification: Gnulib module: sys_resource Portability problems fixed by Gnulib: * This header file is missing on some platforms: mingw, MSVC 9. * On some platforms, this header file requires that and already be included: FreeBSD 5.0. Portability problems not fixed by Gnulib: * On some platforms, this header does not define some or all of the symbolic constants required by POSIX.

Portability problems not fixed by Gnulib: * This header file does not declare the 'msg_control' and 'msg_controllen' members of 'struct msghdr' on some platforms. This can be detected by the absence of the 'CMSG_FIRSTHDR' macro: gnulib replacement header, old BSD 8.63 'sys/stat.h' ================= POSIX specification: Gnulib module: sys_stat Portability problems fixed by Gnulib: * The type 'mode_t' is not defined on some platforms: MSVC 9. * Some macros, such as 'S_IFMT' or 'S_IFIFO', are missing on some platforms. * The macros 'S_ISBLK', 'S_ISCHR', 'S_ISDIR', 'S_ISFIFO', 'S_ISLNK', 'S_ISREG', 'S_ISSOCK' are broken on some platforms. * Some platforms define macros, such as 'S_ISDOOR', that are not defined on other platforms. * The functions 'lstat' and 'mkdir' are not declared on some platforms: mingw, MSVC 9. * The macros 'UTIME_NOW' and 'UTIME_OMIT' are missing on some platforms. * On some platforms, 'struct stat' does not include 'st_atim', 'st_mtim', or 'st_ctim' members. Use the gnulib module 'stat-time' for accessors to portably get at subsecond resolution. Portability problems not fixed by Gnulib: * The macro 'S_IFBLK' is missing on some platforms: MSVC 9. * On Windows platforms (excluding Cygwin), 'st_ino' is always 0. * On OpenVMS, 'st_ino' is an array of three 'ino_t' values, not a single value. * To partially work around the previous two problems, you can test for nonzero 'st_ino' and use the Gnulib 'same-inode' module to compare nonzero values. For example, '(a.st_ino && SAME_INODE (a, b))' is true if the 'struct stat' values 'a' and 'b' are known to represent the same file, '(a.st_ino && !SAME_INODE (a, b))' is true if they are known to represent different files, and '!a.st_ino' is true if it is not known whether they represent different files. * On some platforms, two different files may have the same 'st_dev' and 'st_ino' values, even when 'st_ino' is nonzero: * GNU/Linux NFS servers that export all local file systems as a single NFS file system, if a local 'st_dev' exceeds 255, or if a local 'st_ino' exceeds 16777215. * Network Appliance NFS servers in snapshot directories; see Network Appliance bug #195. * ClearCase MVFS; see bug id ATRia04618. One partial workaround is to compare other file metadata such as 'st_mode' and 'st_mtime' to detect this bug, but this approach does not work on files whose metadata are being changed by other programs. * On some file systems, 'st_size' contains bogus information for symlinks; use the Gnulib module 'areadlink-with-size' for a better way to get symlink contents. 8.64 'sys/statvfs.h' ==================== POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This header file is missing on some platforms: Mac OS X 10.3, OpenBSD 3.8, mingw, MSVC 9. 8.65 'sys/time.h' ================= POSIX specification: Gnulib module: sys_time Portability problems fixed by Gnulib: * This header file is missing on some platforms: MSVC 9. * 'struct timeval' is not defined on some platforms. * 'struct timeval' is defined with a 'tv_sec' type that is narrower than 'time_t' on some native Windows platforms: mingw64 in 64-bit mode, mingw64 in 32-bit mode when '__MINGW_USE_VC2005_COMPAT' is defined, MSVC 9 in 64-bit mode, MSVC 9 in 32-bit mode when '_USE_32BIT_TIME_T' is not defined.

The notation "Gnulib module: --" means that Gnulib does not provide a module providing a substitute for the function. When the list "Portability problems not fixed by Gnulib" is empty, such a module is not needed: No portability problems are known. Otherwise, it indicates that such a module would be useful but is not available: No one so far found this function important enough to contribute a substitute for it.

problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function may overflow its internal buffer if an invalid year is passed. * The 'ctime' function need not be reentrant, and consequently is not required to be thread safe. Implementations of 'ctime' typically write the time stamp into static buffer. If two threads call 'ctime' at roughly the same time, you might end up with the wrong date in one of the threads, or some undefined string. There is a re-entrant interface 'ctime_r'. A more flexible function is 'strftime'. However, note that it is locale dependent. 9.169 'ctime_r' =============== POSIX specification: Gnulib module: extensions Portability problems fixed by Gnulib: * This function has an incompatible declaration on some platforms: Solaris 11 2011-11 (when '_POSIX_PTHREAD_SEMANTICS' is not defined). Portability problems not fixed by Gnulib: * This function is missing on some platforms: mingw, MSVC 9. * This function may put more than 26 bytes into the argument buffer if an invalid year is passed. 'ctime_r' takes a pre-allocated buffer and length of the buffer, and returns 'NULL' on errors. The input buffer should be at least 26 bytes in size. The output string is locale-independent. However, years can have more than 4 digits if 'time_t' is sufficiently wide, so the length of the required output buffer is not easy to determine. Increasing the buffer size when 'ctime_r' returns 'NULL' is not necessarily sufficient. The 'NULL' return value could mean some other error condition, which will not go away by increasing the buffer size. A more flexible function is 'strftime'. However, note that it is locale dependent. 9.170 'daylight' ================ POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This variable is missing on some platforms: Mac OS X 10.3, FreeBSD 6.0, OpenBSD 3.8, IRIX 6.5, OSF/1 5.1. * The address of this variable is not a compile-time constant on some platforms: Cygwin, mingw. 9.171 'dbm_clearerr' ==================== POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, HP-UX 11.11, IRIX 5.3, OSF/1 5.1, Solaris 2.5.1, Cygwin, mingw, MSVC 9, BeOS. 9.172 'dbm_close' ================= POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, Cygwin, mingw, MSVC 9, BeOS. 9.173 'dbm_delete' ================== POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, Cygwin, mingw, MSVC 9, BeOS. 9.174 'dbm_error' ================= POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, HP-UX 11.11, IRIX 5.3, OSF/1 4.0, Solaris 2.5.1, Cygwin, mingw, MSVC 9, BeOS. 9.175 'dbm_fetch' ================= POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, Cygwin, mingw, MSVC 9, BeOS. 9.176 'dbm_firstkey' ==================== POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, Cygwin, mingw, MSVC 9, BeOS. 9.177 'dbm_nextkey' =================== POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, Cygwin, mingw, MSVC 9, BeOS. 9.178 'dbm_open' ================ POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, Cygwin, mingw, MSVC 9, BeOS. 9.179 'dbm_store' ================= POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, Cygwin, mingw, MSVC 9, BeOS. 9.180 'difftime' ================ POSIX specification: Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: 9.181 'dirfd' ============= POSIX specification: Gnulib module: dirfd Portability problems fixed by Gnulib: * This function is missing on some platforms: Minix 3.1.8, AIX 7.1, HP-UX 11, OSF/1 5.1, Solaris 10, mingw, MSVC 9.

Portability problems not fixed by Gnulib: * It is not portable to call 'realloc' with a size of 0. With a NULL pointer argument, this is the same ambiguity as 'malloc (0)' on whether a unique zero-size object is created. With a non-NULL pointer argument, C99 requires that if 'realloc (p, 0)' returns 'NULL' then 'p' is still valid. Among implementations that obey C99, behavior varies on whether 'realloc (p, 0)' always fails and leaves 'p' valid, or usually succeeds and returns a unique zero-size object; either way, a program not suspecting these semantics will leak memory (either the still-valid 'p', or the non-NULL return value). Meanwhile, several implementations violate C99, by always calling 'free (p)' but returning NULL: glibc, Cygwin Extension: Gnulib provides a module 'realloc-gnu' that substitutes a 'realloc' implementation that behaves more like the glibc implementation. 9.848 'realpath' ================ POSIX specification: Gnulib module: canonicalize-lgpl Portability problems fixed by Gnulib: * This function is missing on some platforms: mingw, MSVC 9, BeOS. * This function does not allow for a NULL 'resolved' parameter on some platforms: Mac OS X 10.5, FreeBSD 6.4, OpenBSD 4.4, Solaris 10. * This function does not always return an absolute path on some platforms: Solaris 10. * This function fails to detect trailing slashes on non-directories on some platforms: glibc 2.3.5. * This function fails to recognize non-directories followed '..' on some platforms: cygwin. * This function misbehaves on consecutive slashes on some platforms: AIX 7. Portability problems not fixed by Gnulib: * This function does not allow to determine the required size of output buffer; the use of a non-NULL 'resolved' buffer is non-portable, since PATH_MAX, if it is defined, is nothing more than a guess. 9.849 'recv' ============ POSIX specification: Gnulib module: recv Portability problems fixed by Gnulib: * This function has the return type 'int' instead of 'ssize_t' on some platforms: OSF/1 5.1. * On Windows platforms (excluding Cygwin), error codes for 'recv' are not placed in 'errno', and 'WSAGetLastError' must be used instead.

This opens the door to race conditions: undesired things happen if the signal is triggered twice and the signal handler was not quick enough reinstalling itself as a handler. On BSD platforms and glibc platforms, on the other hand, when the signal is triggered, the kernel blocks the signal before invoking the handler. This is saner, but POSIX still allows either behavior.

This means that the following are not valid here: 'float' Use 'double' instead. 'bool' Use 'int' instead. Integer types smaller than 'int'. Use 'int' or 'unsigned int' instead. This is a portability problem because you don't know the width of some abstract types like 'uid_t', 'gid_t', 'mode_t'. So, instead of mode = va_arg (ap, mode_t); you have to write mode = (sizeof (mode_t) < sizeof (int) ? va_arg (ap, int) : va_arg (ap, mode_t)); 9.1116 'va_copy' ================ POSIX specification: Gnulib module: stdarg Portability problems fixed by Gnulib: * This macro is missing on some platforms: AIX 5.1 with cc or xlc, HP-UX 11 with cc, IRIX 6.5 with cc, OSF/1 5.1 with cc.

Modules ********************* 13.1 alloca =========== The alloca module provides for a function 'alloca' which allocates memory on the stack, where the system allows it. A memory block allocated with 'alloca' exists only until the function that calls 'alloca' returns or exits abruptly. There are a few systems where this is not possible: HP-UX systems, and some other platforms when the C++ compiler is used. On these platforms the alloca module provides a 'malloc' based emulation. This emulation will not free a memory block immediately when the calling function returns, but rather will wait until the next 'alloca' call from a function with the same or a shorter stack length. Thus, in some cases, a few memory blocks will be kept although they are not needed any more. The user can '#include ' and use 'alloca' on all platforms. Note that the '#include ' must be the first one after the autoconf-generated 'config.h', for AIX 3 compatibility. Thanks to IBM for this nice restriction! Note that GCC 3.1 and 3.2 can _inline_ functions that call 'alloca'. When this happens, the memory blocks allocated with 'alloca' will not be freed until _the end of the calling function_. If this calling function runs a loop calling the function that uses 'alloca', the program easily gets a stack overflow and crashes. To protect against this compiler behaviour, you can mark the function that uses 'alloca' with the following attribute: #ifdef __GNUC__ __attribute__ ((__noinline__)) #endif An alternative to this module is the 'alloca-opt' module. 13.2 alloca-opt =============== The alloca-opt module provides for a function 'alloca' which allocates memory on the stack, where the system allows it. A memory block allocated with 'alloca' exists only until the function that calls 'alloca' returns or exits abruptly. There are a few systems where this is not possible: HP-UX systems, and some other platforms when the C++ compiler is used. On these platforms the alloca-opt module provides no replacement, just a preprocessor macro HAVE_ALLOCA. The user can '#include ' on all platforms, and use 'alloca' on those platforms where the preprocessor macro HAVE_ALLOCA evaluates to true. If HAVE_ALLOCA is false, the code should use a heap-based memory allocation based on 'malloc' or (in C++) 'new'. Note that the '#include ' must be the first one after the autoconf-generated 'config.h', for AIX 3 compatibility. Thanks to IBM for this nice restriction! Note that GCC 3.1 and 3.2 can _inline_ functions that call 'alloca'. When this happens, the memory blocks allocated with 'alloca' will not be freed until _the end of the calling function_. If this calling function runs a loop calling the function that uses 'alloca', the program easily gets a stack overflow and crashes. To protect against this compiler behaviour, you can mark the function that uses 'alloca' with the following attribute: #ifdef __GNUC__ __attribute__ ((__noinline__)) #endif 13.3 Safe Allocation Macros =========================== The standard C library malloc/realloc/calloc/free APIs are prone to a number of common coding errors. The 'safe-alloc' module provides macros that make it easier to avoid many of them. It still uses the standard C allocation functions behind the scenes. Some of the memory allocation mistakes that are commonly made are * passing the incorrect number of bytes to 'malloc', especially when allocating an array, * fail to check the return value of 'malloc' and 'realloc' for errors, * forget to fully initialize memory just allocated with 'malloc', * duplicate calls to 'free' by forgetting to set the pointer variable to 'NULL', * leaking memory in calls to 'realloc' when that call fails. The 'safe-alloc' module addresses these problems in the following way: * It defines macros that wrap around the standard C allocation functions. That makes it possible to use the compiler's knowledge of the size of objects for allocation; it also allows setting pointers passed in as arguments when appropriate. * It uses return values only for a success/failure error condition flag, and annotates them with GCC's '__warn_unused_result__' attribute. * It uses 'calloc' instead of 'malloc'. -- Macro: int ALLOC (ptr) Allocate 'sizeof(*ptr)' bytes of memory and store the address of allocated memory in 'ptr'. Fill the newly allocated memory with zeros. Returns -1 on failure, 0 on success. -- Macro: int ALLOC_N (ptr, count) Allocate an array of 'count' elements, each 'sizeof(*ptr)' bytes long, and store the address of allocated memory in 'ptr'. Fill the newly allocated memory with zeros. Returns -1 on failure, 0 on success. -- Macro: int ALLOC_N_UNINITIALIZED (ptr, count) Allocate an array of 'count' elements, each 'sizeof(*ptr)' bytes long, and store the address of allocated memory in 'ptr'. The allocated memory is not initialized. Returns -1 on failure, 0 on success. -- Macro: int REALLOC_N (ptr, count) Reallocate the memory pointed to by 'ptr' to be big enough to hold at least 'count' elements, each 'sizeof(*ptr)' bytes long, and store the address of allocated memory in 'ptr'. If reallocation fails, the 'ptr' variable is not modified. Returns -1 on failure, 0 on success. -- Macro: void FREE (ptr) Free the memory stored in 'ptr' and set 'ptr' to 'NULL'. 13.4 Compile-time Assertions ============================ This module provides a header file 'verify.h' that defines macros related to compile-time verification. Two of these macros are 'verify (V)' and 'verify_expr (V, EXPR)'. Both accept an integer constant expression argument V and verify that it is nonzero. If not, a compile-time error results. These two macros implement compile-time tests, as opposed to the standard 'assert' macro which supports only runtime tests. Since the tests occur at compile-time, they are more reliable, and they require no runtime overhead. 'verify (V);' is a declaration; it can occur outside of functions. In contrast, 'verify_expr (V, EXPR)' is an expression that returns the value of EXPR; it can be used in macros that expand to expressions. If EXPR is an integer constant expression, then 'verify_expr (V, EXPR)' is also an integer constant expression. Although EXPR and 'verify_expr (V, EXPR)' are guaranteed to have the same side effects and value and type (after integer promotion), they need not have the same type if EXPR's type is an integer that is narrower than 'int' or 'unsigned int'. V should be an integer constant expression in the sense of the C standard. Its leaf operands should be integer, enumeration, or character constants; or 'sizeof' expressions that return constants; or floating constants that are the immediate operands of casts. Outside a 'sizeof' subexpression, V should not contain any assignments, function calls, comma operators, casts to non-integer types, or subexpressions whose values are outside the representable ranges for their types. If V is not an integer constant expression, then a compiler might reject a usage like 'verify (V);' even when V is nonzero. Although the standard 'assert' macro is a runtime test, C11 specifies a builtin '_Static_assert (V, STRING-LITERAL)', its 'assert.h' header has a similar macro named 'static_assert', and C++11 has a similar 'static_assert' builtin. These builtins and macros differ from 'verify' in two major ways. First, they can also be used within a 'struct' or 'union' specifier, in place of an ordinary member declaration. Second, they require the programmer to specify a compile-time diagnostic as a string literal. The 'verify.h' header defines one more macro, 'assume (E)', which expands to an expression of type 'void' that causes the compiler to assume that E yields a nonzero value. E should be a scalar expression, and should not have side effects; it may or may not be evaluated. The behavior is undefined if E would yield zero. The main use of 'assume' is optimization, as the compiler may be able to generate better code if it assumes E. For best results, E should be simple enough that a compiler can determine that it has no side effects: if E calls an external function or accesses volatile storage the compiler may not be able to optimize E away and 'assume (E)' may therefore slow down the program. Here are some example uses of these macros. #include #include #include /* Verify that time_t is an integer type. */ verify ((time_t) 1.5 == 1); /* Verify that time_t is no smaller than int. */ verify (sizeof (int) <= sizeof (time_t)); /* Verify that time_t is signed. */ verify ((time_t) -1 < 0); /* Verify that time_t uses two's complement representation. */ verify (~ (time_t) -1 == 0); /* Return the maximum value of the integer type T, verifying that T is an unsigned integer type. The cast to (T) is outside the call to verify_expr so that the result is of type T even when T is narrower than unsigned int. */ #define MAX_UNSIGNED_VAL(t) \ ((T) verify_expr (0 < (T) -1, -1)) /* Return T divided by CHAR_MAX + 1, where behavior is undefined if T < 0. In the common case where CHAR_MAX is 127 the compiler can therefore implement the division by shifting T right 7 bits, an optimization that would not be valid if T were negative. */ time_t time_index (time_t t) { assume (0 <= t); return t / (CHAR_MAX + 1); } 13.5 Integer Properties ======================= The 'intprops' module consists of an include file '' that defines several macros useful for testing properties of integer types. Integer overflow is a common source of problems in programs written in C and other languages. In some cases, such as signed integer arithmetic in C programs, the resulting behavior is undefined, and practical platforms do not always behave as if integers wrap around reliably. In other cases, such as unsigned integer arithmetic in C, the resulting behavior is well-defined, but programs may still misbehave badly after overflow occurs. Many techniques have been proposed to attack these problems. These include precondition testing, wraparound behavior where signed integer arithmetic is guaranteed to be modular, saturation semantics where overflow reliably yields an extreme value, undefined behavior sanitizers where overflow is guaranteed to trap, and various static analysis techniques. Gnulib supports wraparound arithmetic and precondition testing, as these are relatively easy to support portably and efficiently. There are two families of precondition tests: the first, for integer types, is easier to use, while the second, for integer ranges, has a simple and straightforward portable implementation. 13.5.1 Arithmetic Type Properties --------------------------------- 'TYPE_IS_INTEGER (T)' is an arithmetic constant expression that is 1 if the arithmetic type T is an integer type. '_Bool' counts as an integer type. 'TYPE_SIGNED (T)' is an arithmetic constant expression that is 1 if the real type T is a signed integer type or a floating type. If T is an integer type, 'TYPE_SIGNED (T)' is an integer constant expression. 'EXPR_SIGNED (E)' is 1 if the real expression E has a signed integer type or a floating type. If E is an integer constant expression or an arithmetic constant expression, 'EXPR_SIGNED (E)' is likewise. Although E is evaluated, if E is free of side effects then 'EXPR_SIGNED (E)' is typically optimized to a constant. Example usage: #include #include enum { time_t_is_signed_integer = TYPE_IS_INTEGER (time_t) && TYPE_SIGNED (time_t) }; int CLOCKS_PER_SEC_is_signed (void) { return EXPR_SIGNED (CLOCKS_PER_SEC); } 13.5.2 Integer Bounds --------------------- 'INT_BUFSIZE_BOUND (T)' is an integer constant expression that is a bound on the size of the string representing an integer type or expression T in decimal notation, including the terminating null character and any leading '-' character. For example, if 'INT_STRLEN_BOUND (int)' is 12, any value of type 'int' can be represented in 12 bytes or less, including the terminating null. The bound is not necessarily tight. Example usage: #include #include int int_strlen (int i) { char buf[INT_BUFSIZE_BOUND (int)]; return sprintf (buf, "%d", i); } 'INT_STRLEN_BOUND (T)' is an integer constant expression that is a bound on the length of the string representing an integer type or expression T in decimal notation, including any leading '-' character. This is one less than 'INT_BUFSIZE_BOUND (T)'. 'TYPE_MINIMUM (T)' and 'TYPE_MAXIMUM (T)' are integer constant expressions equal to the minimum and maximum values of the integer type T. These expressions are of the type T (or more precisely, the type T after integer promotions). Example usage: #include #include #include int in_off_t_range (intmax_t a) { return TYPE_MINIMUM (off_t) <= a && a <= TYPE_MAXIMUM (off_t); } 13.5.3 Wraparound Arithmetic with Signed Integers ------------------------------------------------- Signed integer arithmetic has undefined behavior on overflow in C. Although almost all modern computers use two's complement signed arithmetic that is well-defined to wrap around, C compilers routinely optimize assuming that signed integer overflow cannot occur, which means that a C program cannot easily get at the underlying machine arithmetic. For example, on a typical machine with 32-bit two's complement 'int' the expression 'INT_MAX + 1' does not necessarily yield 'INT_MIN', because the compiler may do calculations with a 64-bit register, or may generate code that traps on signed integer overflow. The following macros work around this problem by storing the wraparound value, i.e., the low-order bits of the correct answer, and by returning an overflow indication. For example, if 'i' is of type 'int', 'INT_ADD_WRAPV (INT_MAX, 1, &i)' sets 'i' to 'INT_MIN' and returns 1 on a two's complement machine. On newer platforms, these macros are typically more efficient than the overflow-checking macros. *Note Integer Type Overflow::. Example usage: #include #include /* Print the low order bits of A * B, reporting whether overflow occurred. */ void print_product (long int a, long int b) { long int r; int overflow = INT_MULTIPLY_WRAPV (a, b, &r); printf ("result is %ld (%s)\n", r, (overflow ? "after overflow" : "no overflow")); } These macros have the following restrictions: * Their first two arguments must be integer expressions. * Their last argument must be a non-null pointer to a signed integer. To calculate a wraparound unsigned integer you can use ordinary C arithmetic; to tell whether it overflowed, you can use the overflow-checking macros. * They may evaluate their arguments zero or multiple times, so the arguments should not have side effects. * They are not necessarily constant expressions, even if all their arguments are constant expressions. 'INT_ADD_WRAPV (A, B, R)' Store the low-order bits of the sum of A and B into '*R'. Return true if overflow occurred, false if the low-order bits are the mathematically-correct sum. See above for restrictions. 'INT_SUBTRACT_WRAPV (A, B, R)' Store the low-order bits of the difference between A and B into '*R'. Return true if overflow occurred, false if the low-order bits are the mathematically-correct difference. See above for restrictions. 'INT_MULTIPLY_WRAPV (A, B, R)' Store the low-order bits of the product of A and B into '*R'. Return true if overflow occurred, false if the low-order bits are the mathematically-correct product. See above for restrictions. 13.5.4 Integer Type Overflow ---------------------------- Although unsigned integer arithmetic wraps around modulo a power of two, signed integer arithmetic has undefined behavior on overflow in C. Almost all modern computers use two's complement signed arithmetic that is well-defined to wrap around, but C compilers routinely optimize based on the assumption that signed integer overflow cannot occur, which means that a C program cannot easily get at the underlying machine behavior. For example, the signed integer expression '(a + b < b) != (a < 0)' is not a reliable test for whether 'a + b' overflows, because a compiler can assume that signed overflow cannot occur and treat the entire expression as if it were false. These macros yield 1 if the corresponding C operators might not yield numerically correct answers due to arithmetic overflow of an integer type. They work correctly on all known practical hosts, and do not rely on undefined behavior due to signed arithmetic overflow. They are integer constant expressions if their arguments are. They are typically easier to use than the integer range overflow macros (*note Integer Range Overflow::), and they support more operations and evaluation contexts than the wraparound macros (*note Wraparound Arithmetic::). Example usage: #include #include #include /* Print A * B if in range, an overflow indicator otherwise. */ void print_product (long int a, long int b) { if (INT_MULTIPLY_OVERFLOW (a, b)) printf ("multiply would overflow"); else printf ("product is %ld", a * b); } /* Does the product of two ints always fit in a long int? */ enum { INT_PRODUCTS_FIT_IN_LONG = ! (INT_MULTIPLY_OVERFLOW ((long int) INT_MIN, INT_MIN)) }; These macros have the following restrictions: * Their arguments must be integer expressions. * They may evaluate their arguments zero or multiple times, so the arguments should not have side effects. These macros are tuned for their last argument being a constant. 'INT_ADD_OVERFLOW (A, B)' Yield 1 if 'A + B' would overflow. See above for restrictions. 'INT_SUBTRACT_OVERFLOW (A, B)' Yield 1 if 'A - B' would overflow. See above for restrictions. 'INT_NEGATE_OVERFLOW (A)' Yields 1 if '-A' would overflow. See above for restrictions. 'INT_MULTIPLY_OVERFLOW (A, B)' Yield 1 if 'A * B' would overflow. See above for restrictions. 'INT_DIVIDE_OVERFLOW (A, B)' Yields 1 if 'A / B' would overflow. See above for restrictions. Division overflow can happen on two's complement hosts when dividing the most negative integer by -1. This macro does not check for division by zero. 'INT_REMAINDER_OVERFLOW (A, B)' Yield 1 if 'A % B' would overflow. See above for restrictions. Remainder overflow can happen on two's complement hosts when dividing the most negative integer by -1; although the mathematical result is always 0, in practice some implementations trap, so this counts as an overflow. This macro does not check for division by zero. 'INT_LEFT_SHIFT_OVERFLOW (A, B)' Yield 1 if 'A << B' would overflow. See above for restrictions. The C standard says that behavior is undefined for shifts unless 0<=B #include #include void print_product (long int a, long int b) { if (INT_MULTIPLY_RANGE_OVERFLOW (a, b, LONG_MIN, LONG_MAX)) printf ("multiply would overflow"); else printf ("product is %ld", a * b); } /* Does the product of two ints always fit in a long int? */ enum { INT_PRODUCTS_FIT_IN_LONG = ! (INT_MULTIPLY_RANGE_OVERFLOW ((long int) INT_MIN, (long int) INT_MIN, LONG_MIN, LONG_MAX)) }; These macros have the following restrictions: * Their arguments must be integer expressions. * They may evaluate their arguments zero or multiple times, so the arguments should not have side effects. * The arithmetic arguments (including the MIN and MAX arguments) must be of the same integer type after the usual arithmetic conversions, and the type must have minimum value MIN and maximum MAX. Unsigned values should use a zero MIN of the proper type, for example, '(unsigned int) 0'. These macros are tuned for constant MIN and MAX. For commutative operations such as 'A + B', they are also tuned for constant B. 'INT_ADD_RANGE_OVERFLOW (A, B, MIN, MAX)' Yield 1 if 'A + B' would overflow in [MIN,MAX] integer arithmetic. See above for restrictions. 'INT_SUBTRACT_RANGE_OVERFLOW (A, B, MIN, MAX)' Yield 1 if 'A - B' would overflow in [MIN,MAX] integer arithmetic. See above for restrictions. 'INT_NEGATE_RANGE_OVERFLOW (A, MIN, MAX)' Yield 1 if '-A' would overflow in [MIN,MAX] integer arithmetic. See above for restrictions. 'INT_MULTIPLY_RANGE_OVERFLOW (A, B, MIN, MAX)' Yield 1 if 'A * B' would overflow in [MIN,MAX] integer arithmetic. See above for restrictions. 'INT_DIVIDE_RANGE_OVERFLOW (A, B, MIN, MAX)' Yield 1 if 'A / B' would overflow in [MIN,MAX] integer arithmetic. See above for restrictions. Division overflow can happen on two's complement hosts when dividing the most negative integer by -1. This macro does not check for division by zero. 'INT_REMAINDER_RANGE_OVERFLOW (A, B, MIN, MAX)' Yield 1 if 'A % B' would overflow in [MIN,MAX] integer arithmetic. See above for restrictions. Remainder overflow can happen on two's complement hosts when dividing the most negative integer by -1; although the mathematical result is always 0, in practice some implementations trap, so this counts as an overflow. This macro does not check for division by zero. 'INT_LEFT_SHIFT_RANGE_OVERFLOW (A, B, MIN, MAX)' Yield 1 if 'A << B' would overflow in [MIN,MAX] integer arithmetic. See above for restrictions. Here, MIN and MAX are for A only, and B need not be of the same type as the other arguments. The C standard says that behavior is undefined for shifts unless 0<=B #define AAA_INLINE _GL_EXTERN_INLINE #include whereas 'bbb.c' and 'ccc.c' can include 'aaa.h' in the usual way. C99 compilers expand 'AAA_INLINE' to C99-style 'inline' usage, where 'aaa_fun' is declared 'extern inline' in 'aaa.c' and plain 'inline' in other modules. Pre-C99 compilers that are compatible with GCC use GCC-specific syntax to accomplish the same ends. Other pre-C99 compilers use 'static inline' so they suffer from code bloat, but they are not mainline platforms and will die out eventually. '_GL_INLINE' is a portable alternative to C99 plain 'inline'. '_GL_EXTERN_INLINE' is a portable alternative to C99 'extern inline'. Invoke '_GL_INLINE_HEADER_BEGIN' before all uses of '_GL_INLINE' in an include file. This suppresses some bogus warnings in GCC versions before 5.1. If an include file includes other files, it is better to invoke this macro after including the other files. Invoke '_GL_INLINE_HEADER_END' after all uses of '_GL_INLINE' in an include file. 13.7 Character and String Functions in C Locale =============================================== The functions in this section are similar to the generic string functions from the standard C library, except that * They behave as if the locale was set to the "C" locale, even when the locale is different, and/or * They are specially optimized for the case where all characters are plain ASCII characters. 13.7.1 c-ctype -------------- The 'c-ctype' module contains functions operating on single-byte characters, like the functions in '', that operate as if the locale encoding was ASCII. (The "C" locale on many systems has the locale encoding "ASCII".) The functions are: extern bool c_isascii (int c); extern bool c_isalnum (int c); extern bool c_isalpha (int c); extern bool c_isblank (int c); extern bool c_iscntrl (int c); extern bool c_isdigit (int c); extern bool c_islower (int c); extern bool c_isgraph (int c); extern bool c_isprint (int c); extern bool c_ispunct (int c); extern bool c_isspace (int c); extern bool c_isupper (int c); extern bool c_isxdigit (int c); extern int c_tolower (int c); extern int c_toupper (int c); These functions assign properties only to ASCII characters. The C argument can be a 'char' or 'unsigned char' value, whereas the corresponding functions in '' take an argument that is actually an 'unsigned char' value. The 'c_is*' functions return 'bool', where the corresponding functions in '' return 'int' for historical reasons. Note: The '' functions support only unibyte locales. 13.7.2 c-strcase ---------------- The 'c-strcase' module contains case-insensitive string comparison functions operating on single-byte character strings, like the functions in '', that operate as if the locale encoding was ASCII. (The "C" locale on many systems has the locale encoding "ASCII".) The functions are: extern int c_strcasecmp (const char *s1, const char *s2); extern int c_strncasecmp (const char *s1, const char *s2, size_t n); For case conversion here, only ASCII characters are considered to be upper case or lower case. Note: The functions 'strcasecmp', 'strncasecmp' from '' support only unibyte locales; for multibyte locales, you need the functions 'mbscasecmp', 'mbsncasecmp', 'mbspcasecmp'. 13.7.3 c-strcaseeq ------------------ The 'c-strcaseeq' module contains an optimized case-insensitive string comparison function operating on single-byte character strings, that operate as if the locale encoding was ASCII. (The "C" locale on many systems has the locale encoding "ASCII".) The functions is actually implemented as a macro: extern int STRCASEEQ (const char *s1, const char *s2, int s20, int s21, int s22, int s23, int s24, int s25, int s26, int s27, int s28); S2 should be a short literal ASCII string, and S20, S21, ... the individual characters of S2. For case conversion here, only ASCII characters are considered to be upper case or lower case. 13.7.4 c-strcasestr ------------------- The 'c-strcasestr' module contains a case-insensitive string search function operating on single-byte character strings, that operate as if the locale encoding was ASCII. (The "C" locale on many systems has the locale encoding "ASCII".) The function is: extern char *c_strcasestr (const char *haystack, const char *needle); For case conversion here, only ASCII characters are considered to be upper case or lower case. Note: The function 'strcasestr' from '' supports only unibyte locales; for multibyte locales, you need the function 'mbscasestr'. 13.7.5 c-strstr --------------- The 'c-strstr' module contains a substring search function operating on single-byte character strings, that operate as if the locale encoding was ASCII. (The "C" locale on many systems has the locale encoding "ASCII".) The function is: extern char *c_strstr (const char *haystack, const char *needle); Note: The function 'strstr' from '' supports only unibyte locales; for multibyte locales, you need the function 'mbsstr'. 13.7.6 c-strtod --------------- The 'c-strtod' module contains a string to number ('double') conversion function operating on single-byte character strings, that operates as if the locale encoding was ASCII. (The "C" locale on many systems has the locale encoding "ASCII".) The function is: extern double c_strtod (const char *string, char **endp); In particular, only a period '.' is accepted as decimal point, even when the current locale's notion of decimal point is a comma ',', and no characters outside the basic character set are accepted. On platforms without 'strtod_l', this function is not safe for use in multi-threaded applications since it calls 'setlocale'. 13.7.7 c-strtold ---------------- The 'c-strtold' module contains a string to number ('long double') conversion function operating on single-byte character strings, that operates as if the locale encoding was ASCII. (The "C" locale on many systems has the locale encoding "ASCII".) The function is: extern long double c_strtold (const char *string, char **endp); In particular, only a period '.' is accepted as decimal point, even when the current locale's notion of decimal point is a comma ','. 13.8 Quoting ============ Gnulib provides 'quote' and 'quotearg' modules to help with quoting text, such as file names, in messages to the user. Here's an example of using 'quote': #include ... error (0, errno, _("cannot change owner of %s"), quote (fname)); This differs from error (0, errno, _("cannot change owner of '%s'"), fname); in that 'quote' escapes unusual characters in 'fname', e.g., ''' and control characters like '\n'. However, a caveat: 'quote' reuses the storage that it returns. Hence if you need more than one thing quoted at the same time, you need to use 'quote_n'. Also, the quote module is not suited for multithreaded applications. In that case, you have to use 'quotearg_alloc', defined in the 'quotearg' module, which is decidedly less convenient. 13.9 error and progname ======================= The 'error' function uses the 'program_name' variable, but does not depend on the 'progname' module. Why? Because 'error' is released under the LGPL, whereas 'progname' is GPL. RMS does not want additional baggage accompanying the 'error' module, so an LGPL user must provide their own replacement 'program_name', and a GPL user should manually specify using the 'progname' module. Additionally, using the 'progname' module is not something that can be done implicitly. It requires that every 'main' function be modified to set 'program_name' as one of its first actions. 13.10 gcd: greatest common divisor ================================== The 'gcd' function returns the greatest common divisor of two numbers 'a > 0' and 'b > 0'. It is the caller's responsibility to ensure that the arguments are non-zero. If you need a gcd function for an integer type larger than 'unsigned long', you can include the 'gcd.c' implementation file with parametrization. The parameters are: * WORD_T Define this to the unsigned integer type that you need this function for. * GCD Define this to the name of the function to be created. The created function has the prototype WORD_T GCD (WORD_T a, WORD_T b); If you need the least common multiple of two numbers, it can be computed like this: 'lcm(a,b) = (a / gcd(a,b)) * b' or 'lcm(a,b) = a * (b / gcd(a,b))'. Avoid the formula 'lcm(a,b) = (a * b) / gcd(a,b)' because--although mathematically correct--it can yield a wrong result, due to integer overflow. In some applications it is useful to have a function taking the gcd of two signed numbers. In this case, the gcd function result is usually normalized to be non-negative (so that two gcd results can be compared in magnitude or compared against 1, etc.). Note that in this case the prototype of the function has to be unsigned long gcd (long a, long b); and not long gcd (long a, long b); because 'gcd(LONG_MIN,LONG_MIN) = -LONG_MIN = LONG_MAX + 1' does not fit into a signed 'long'. 13.11 Searching for Libraries ============================= The following macros check for the presence or location of certain C, C++, or Fortran library archive files. Simple Library Tests -------------------- The macros 'AC_CHECK_LIB', 'AC_SEARCH_LIBS' from GNU Autoconf check for the presence of certain C, C++, or Fortran library archive files. The libraries are looked up in the default linker path--a system dependent list of directories, that usually contains the '/usr/lib' directory--and those directories given by '-L' options in the 'LDFLAGS' variable. Locating Libraries ------------------ The following macros, defined in the Gnulib module 'havelib', search for the location of certain C, C++, or Fortran library archive files and make the found location available to the compilation process and to further Autoconf tests. -- Macro: 'AC_LIB_LINKFLAGS(NAME, [DEPENDENCIES])' Searches for 'lib' and the libraries corresponding to explicit and implicit dependencies. Sets and AC_SUBSTs the 'LIB' and 'LTLIB' variables (with '' in upper case) and augments the 'CPPFLAGS' variable by '-I' options. This macro should be used when 'lib' is expected to be found. -- Macro: 'AC_LIB_HAVE_LINKFLAGS(NAME, [DEPENDENCIES], [INCLUDES], [TESTCODE], [MISSING-MESSAGE])' Searches for 'lib' and the libraries corresponding to explicit and implicit dependencies, together with the specified include files and the ability to compile and link the specified TESTCODE. The MISSING-MESSAGE defaults to 'no' and may contain additional hints for the user. If found, it sets and AC_SUBSTs 'HAVE_LIB=yes' and the 'LIB' and 'LTLIB' variables (with '' in upper case) and augments the 'CPPFLAGS' variable by '-I' options, and #defines 'HAVE_LIB' to 1. Otherwise, it sets and AC_SUBSTs 'HAVE_LIB=no' and 'LIB' and 'LTLIB' to empty. These macros assume that when a library is installed in 'SOME_DIRECTORY/lib', its include files are installed in 'SOME_DIRECTORY/include'. The complexities that 'AC_LIB_LINKFLAGS' and 'AC_LIB_HAVE_LINKFLAGS' deal with are the following: * The library is not necessarily already in the search path ('CPPFLAGS' for the include file search path, 'LDFLAGS' for the library search path). The macro provides a '--with-lib' option. The user of the 'configure' script can use this option to indicate the location of the library and its include files. If not provided, the '--prefix' directory is searched as well. * The library is not necessarily already in the run time library search path. To avoid the need for setting an environment variable like 'LD_LIBRARY_PATH', the macro adds the appropriate run time search path options to the 'LIB' variable. This works on most systems. It can also be inhibited: The user of 'configure' can use the '--disable-rpath' option to force an installation that doesn't contain hardcoded library search paths but instead may require the use of an environment variable like 'LD_LIBRARY_PATH'. The macros also set a variable 'LTLIB', that should be used when linking with libtool. Both 'LTLIB' and 'LIB' contain essentially the same option, but where 'LIB' contains platform dependent flags like '-Wl,-rpath', 'LTLIB' contains platform independent flags like '-R'. Example of using 'AC_LIB_LINKFLAGS' ................................... Suppose you want to use 'libz', the compression library. 1. In configure.ac you add the line AC_CONFIG_AUX_DIR([build-aux]) AC_LIB_LINKFLAGS([z]) Note that since the 'AC_LIB_LINKFLAGS' invocation modifies the CPPFLAGS, it should precede all tests that check for header files, declarations, structures or types. 2. To the package's 'build-aux' directory you add the file 'config.rpath', also part of the Gnulib 'havelib' module. ('gnulib-tool' will usually do this for you automatically.) 3. In 'Makefile.in' you add '@LIBZ@' to the link command line of your program. Or, if you are using Automake, you add '$(LIBZ)' to the 'LDADD' variable that corresponds to your program. Dependencies ............ The dependencies list is a space separated list of library names that 'libNAME' is known to depend upon. Example: If 'libfooy' depends on 'libfoox', and 'libfooz' depends on 'libfoox' and 'libfooy', you can write: AC_LIB_LINKFLAGS([foox]) AC_LIB_LINKFLAGS([fooy], [foox]) AC_LIB_LINKFLAGS([fooz], [foox fooy]) Explicit dependencies are necessary if you cannot assume that a '.la' file, created by libtool, is installed. If you can assume that 'libfooy.la' is installed by libtool (and has not been omitted by the package distributor!), you can omit the explicit dependency and just write AC_LIB_LINKFLAGS([fooy]) This way, you don't need to know in advance which libraries the needed library depends upon. Static vs. shared ................. The macros find the libraries regardless whether they are installed as shared or static libraries. 'CPPFLAGS' vs. 'LDFLAGS' ........................ The macros determine the directories that should be added to the compiler preprocessor's search path and to the linker's search path. For the compiler preprocessor, '-I' options with the necessary directories are added to the 'CPPFLAGS' variable, for use by the whole package. For the linker, appropriate options are added to the 'LIB' and 'LTLIB' variables, for use during linking by those programs and libraries that need the dependency on 'lib'. You need to use the value of 'LIB' or 'LTLIB' in the Makefiles. 'LTLIB' is for use with libtool, whereas 'LIB' is for when libtool is not involved in linking. The macros do not check whether the include files and the library found match. If you want to verify this at configure time, one technique is to have a version number in the include files and a version number in the library, like this: #define LIBNAME_VERSION 10203 extern int libNAME_version; /* initialized to LIBNAME_VERSION */ and use a test like AC_TRY_RUN([int main () { return libNAME_version != LIBNAME_VERSION; }]) Bi-arch systems ............... A bi-arch system is one where * the processor has a 32-bit execution mode and a 64-bit execution mode (for example, x86_64, ia64, sparc64, powerpc64), and * 32-bit mode libraries and executables and 64-bit mode libraries are both installed, and * 32-bit mode libraries and object files cannot be mixed with 64-bit mode ones. On several types of such systems, for historical reasons, the 32-bit libraries are installed in 'PREFIX/lib', whereas the 64-bit libraries are installed in * 'PREFIX/lib64' on many glibc systems, * 'PREFIX/lib/64' on Solaris systems. On such systems, in 64-bit mode, 'configure' will search for the libraries in 'PREFIX/lib64' or 'PREFIX/lib/64', respectively, not in 'PREFIX/lib'. A user can adhere to these system-wide conventions by using the '--libdir' option when installing packages. When a user has already installed packages in 64-bit mode using the GNU default '--libdir=PREFIX/lib', he can make this directory adhere to the system-wide convention by placing a symbolic link: On glibc systems: 'ln -s lib PREFIX/lib64' On Solaris systems: 'ln -s . PREFIX/lib/64' 13.12 Controlling the Exported Symbols of Shared Libraries ========================================================== The 'lib-symbol-visibility' module allows precise control of the symbols exported by a shared library. This is useful because * It prevents abuse of undocumented APIs of your library. Symbols that are not exported from the library cannot be used. This eliminates the problem that when the maintainer of the library changes internals of the library, maintainers of other projects cry "breakage". Instead, these maintainers are forced to negotiate the desired API from the maintainer of the library. * It reduces the risk of symbol collision between your library and other libraries. For example, the symbol 'readline' is defined in several libraries, most of which don't have the same semantics and the same calling convention as the GNU readline library. * It reduces the startup time of programs linked to the library. This is because the dynamic loader has less symbols to process. * It allows the compiler to generate better code. Within a shared library, a call to a function that is a global symbol costs a "call" instruction to a code location in the so-called PLT (procedure linkage table) which contains a "jump" instruction to the actual function's code. (This is needed so that the function can be overridden, for example by a function with the same name in the executable or in a shared library interposed with 'LD_PRELOAD'.) Whereas a call to a function for which the compiler can assume that it is in the same shared library is just a direct "call" instructions. Similarly for variables: A reference to a global variable fetches a pointer in the so-called GOT (global offset table); this is a pointer to the variable's memory. So the code to access it is two memory load instructions. Whereas for a variable which is known to reside in the same shared library, it is just a direct memory access: one memory load instruction. There are traditionally three ways to specify the exported symbols of a shared library. * The programmer specifies the list of symbols to be exported when the shared library is created. Usually a command-line option is passed to the linker, with the name of a file containing the symbols. The upside of this approach is flexibility: it allows the same code to be used in different libraries with different export lists. The downsides are: 1. it's a lot of maintenance overhead when the symbol list is platform dependent, 2. it doesn't work well with C++, due to name mangling. * The programmer specifies a "hidden" attribute for every variable and function that shall not be exported. The drawbacks of this approach are: Symbols are still exported from the library by default. It's a lot of maintenance work to mark every non- exported variable and function. But usually the exported API is quite small, compared to the internal API of the library. And it's the wrong paradigm: It doesn't force thinking when introducing new exported API. * The programmer specifies a "hidden" attribute for all files that make up the shared library, and an "exported" attribute for those symbols in these files that shall be exported. This is perfect: It burdens the maintainer only for exported API, not for library-internal API. And it keeps the annotations in the source code. GNU libtool's '-export-symbols' option implements the first approach. This gnulib module implements the third approach. For this it relies on GNU GCC 4.0 or newer, namely on its '-fvisibility=hidden' command-line option and the "visibility" attribute. (The "visibility" attribute was already supported in GCC 3.4, but without the command line option, introduced in GCC 4.0, the third approach could not be used.) More explanations on this subject can be found in , which contains more details on the GCC features and additional advice for C++ libraries, and in Ulrich Drepper's paper , which also explains other tricks for reducing the startup time impact of shared libraries. The gnulib autoconf macro 'gl_VISIBILITY' tests for GCC 4.0 or newer. It defines a Makefile variable '@CFLAG_VISIBILITY@' containing '-fvisibility=hidden' or nothing. It also defines as a C macro and as a substituted variable: @HAVE_VISIBILITY@. Its value is 1 when symbol visibility control is supported, and 0 otherwise. To use this module in a library, say libfoo, you will do these steps: 1. Add '@CFLAG_VISIBILITY@' or (in a Makefile.am) '$(CFLAG_VISIBILITY)' to the CFLAGS for the compilation of the sources that make up the library. 2. Add a C macro definition, say '-DBUILDING_LIBFOO', to the CPPFLAGS for the compilation of the sources that make up the library. 3. Define a macro specific to your library like this. #if BUILDING_LIBFOO && HAVE_VISIBILITY #define LIBFOO_DLL_EXPORTED __attribute__((__visibility__("default"))) #else #define LIBFOO_DLL_EXPORTED #endif This macro should be enabled in all public header files of your library. 4. Annotate all variable, function and class declarations in all public header files of your library with 'LIBFOO_DLL_EXPORTED'. This annotation can occur at different locations: between the 'extern' and the type or return type, or just before the entity being declared, or after the entire declarator. My preference is to put it right after 'extern', so that the declarations in the header files remain halfway readable. Note that the precise control of the exported symbols will not work with other compilers than GCC >= 4.0, and will not work on systems where the assembler or linker lack the support of "hidden" visibility. Therefore, it's good if, in order to reduce the risk of collisions with symbols in other libraries, you continue to use a prefix specific to your library for all non-static variables and functions and for all C++ classes in your library. Note about other compilers: MSVC support can be added easily, by extending the definition of the macro mentioned above, to something like this: #if BUILDING_LIBFOO && HAVE_VISIBILITY #define LIBFOO_DLL_EXPORTED __attribute__((__visibility__("default"))) #elif BUILDING_LIBFOO && defined _MSC_VER #define LIBFOO_DLL_EXPORTED __declspec(dllexport) #elif defined _MSC_VER #define LIBFOO_DLL_EXPORTED __declspec(dllimport) #else #define LIBFOO_DLL_EXPORTED #endif 13.13 LD Version Scripts ======================== The 'lib-symbol-versions' module can be used to add shared library versioning support. Currently, only GNU LD and the Solaris linker supports this. Version scripts provides information that can be used by GNU/Linux distribution packaging tools. For example, Debian has a tool 'dpkg-shlibdeps' that can determine the minimal required version of each dependency (by looking at the symbol list) and stuff the information into the Debian specific packaging files. For more information and other uses of version scripts, see Ulrich Drepper's paper You use the module by importing it to your library, and then add the following lines to the 'Makefile.am' that builds the library: if HAVE_LD_VERSION_SCRIPT libfoo_la_LDFLAGS += -Wl,--version-script=$(srcdir)/libfoo.map endif The version script file format is documented in the GNU LD manual, but a small example would be: LIBFOO_1.0 { global: libfoo_init; libfoo_doit; libfoo_done; local: *; }; If you target platforms that do not support linker scripts (i.e., all platforms that doesn't use GNU LD) you may want to consider a more portable but less powerful alternative: libtool '-export-symbols'. It will hide internal symbols from your library, but will not add ELF versioning symbols. Your usage would then be something like: if HAVE_LD_VERSION_SCRIPT libfoo_la_LDFLAGS += -Wl,--version-script=$(srcdir)/libfoo.map else libfoo_la_LDFLAGS += -export-symbols $(srcdir)/libfoo.sym endif See the Libtool manual for the file syntax, but a small example would be: libfoo_init libfoo_doit libfoo_done To avoid the need for a '*.sym' file if your symbols are easily expressed using a regular expression, you may use '-export-symbols-regex': if HAVE_LD_VERSION_SCRIPT libfoo_la_LDFLAGS += -Wl,--version-script=$(srcdir)/libfoo.map else libfoo_la_LDFLAGS += -export-symbols-regex '^libfoo_.*' endif For more discussions about symbol visibility, rather than shared library versioning, see the 'visibility' module (*note Exported Symbols of Shared Libraries::). 13.14 Visual Studio Compatibility ================================= The 'lib-msvc-compat' module detects whether the linker supports '--output-def' when building a library. That parameter is used to generate a DEF file for a shared library (DLL). DEF files are useful for developers that use Visual Studio to develop programs that links to your library. See the GNU LD manual for more information. There are other ways to create a DEF file, but we believe they are all sub-optimal to using '--output-def' during the build process. The variants we have considered include: * Use DUMPBIN /EXPORTS. This is explained in . The tool does not generate DEF files directly, so its output needs to be post processed manually: $ { echo EXPORTS; \ dumpbin /EXPORTS libfoo-0.dll | tail -n+20 | awk '{ print $4 }'; \ } > libfoo-0.def $ lib /def:libfoo-0.def * Use IMPDEF. There is a tool called IMPDEF () that can generate DEF files. However, it is not part of a standard Visual Studio installation. Further, it is documented as being an unreliable process. * Use DLLTOOL. The dlltool is part of the MinGW suite, and thus not part of a standard Visual Studio installation. The documentation for the IMPDEF tool claims that DLLTOOL is the wrong tool for this job. Finally, DLLTOOL does not generate DEF files directly, so it requires post-processing of the output. If you are using libtool to build your shared library, here is how to use this module. Import 'lib-msvc-compat' to your project, and then add the following lines to the 'Makefile.am' that builds the library: if HAVE_LD_OUTPUT_DEF libfoo_la_LDFLAGS += -Wl,--output-def,libfoo-$(DLL_VERSION).def defexecdir = $(bindir) defexec_DATA = libfoo-$(DLL_VERSION).def DISTCLEANFILES += $(defexec_DATA) endif The 'DLL_VERSION' variable needs to be defined. It should be the shared library version number used in the DLL filename. For Windows targets you compute this value from the values you pass to Libtool's '-version-info'. Assuming you have variables 'LT_CURRENT' and 'LT_AGE' defined for the 'CURRENT' and 'AGE' libtool version integers, you compute 'DLL_VERSION' as follows: DLL_VERSION=`expr ${LT_CURRENT} - ${LT_AGE}` AC_SUBST(DLL_VERSION) 13.15 Supporting Relocation =========================== It has been a pain for many users of GNU packages for a long time that packages are not relocatable. It means a user cannot copy a program, installed by another user on the same machine, to his home directory, and have it work correctly (including i18n). So many users need to go through 'configure; make; make install' with all its dependencies, options, and hurdles. Red Hat, Debian, and other binary distributions solve the "ease of installation" problem, but they hardwire path names, usually to '/usr' or '/usr/local'. This means that users need root privileges to install a binary package, and prevents installing two different versions of the same binary package. A relocatable program can be moved or copied to a different location on the file system. It is possible to make symlinks to the installed and moved programs, and invoke them through the symlink. It is possible to do the same thing with a hard link _only_ if the hard link file is in the same directory as the real program. The 'relocatable-prog' module aims to ease the process of making a GNU program relocatable. It helps overcome two obstacles. First, it aids with relocating the hard-coded references to absolute file names that GNU programs often contain. These references must be fixed up at runtime if a program is to be successfully relocated. The 'relocatable-prog' module provides a function 'relocate' that does this job. Second, the loader must be able to find shared libraries linked to relocatable executables or referenced by other shared libraries linked to relocatable executables. The 'relocatable-prog' module helps out here in a platform-specific way: * On GNU/Linux, it adds a linker option ('-rpath') that causes the dynamic linker to search for libraries in a directory relative to the location of the invoked executable. * On other Unix systems, it installs a wrapper executable. The wrapper sets the environment variable that controls shared library searching (usually 'LD_LIBRARY_PATH') and then invokes the real executable. This approach does not always work. On OpenBSD and OpenServer, prereleases of Libtool 1.5 put absolute file names of libraries in executables, which prevents searching any other locations. * On Windows, the executable's own directory is searched for libraries, so installing shared libraries into the executable's directory is sufficient. You can make your program relocatable by following these steps: 1. Import the 'relocatable-prog' module. 2. In every program, add to 'main' as the first statement (even before setting the locale or doing anything related to libintl): set_program_name (argv[0]); The prototype for this function is in 'progname.h'. 3. Everywhere where you use a constant pathname from installation-time, wrap it in 'relocate' so it gets translated to the run-time situation. Example: bindtextdomain (PACKAGE, LOCALEDIR); becomes: bindtextdomain (PACKAGE, relocate (LOCALEDIR)); The prototype for this function is in 'relocatable.h'. 4. The 'set_program_name' function can also configure some additional libraries to relocate files that they access, by defining corresponding C preprocessor symbols to 1. The libraries for which this is supported and the corresponding preprocessor symbols are: libcharset 'DEPENDS_ON_LIBCHARSET' libiconv 'DEPENDS_ON_LIBICONV' libintl 'DEPENDS_ON_LIBINTL' Defining the symbol for a library makes every program in the package depend on that library, whether the program really uses the library or not, so this feature should be used with some caution. 5. If your package installs shell scripts, also import the 'relocatable-script' module. Then, near the beginning of each shell script that your package installs, add the following: @relocatable_sh@ if test "@RELOCATABLE@" = yes; then exec_prefix="@exec_prefix@" bindir="@bindir@" orig_installdir="$bindir" # see Makefile.am's *_SCRIPTS variables func_find_curr_installdir # determine curr_installdir func_find_prefixes relocate () { echo "$1/" \ | sed -e "s%^${orig_installprefix}/%${curr_installprefix}/%" \ | sed -e 's,/$,,' } else relocate () { echo "$1" } fi # Get some relocated directory names. sysconfdir=`relocate "@sysconfdir@"` some_datadir=`relocate "@datadir@/something"` You must adapt the definition of 'orig_installdir', depending on where the script gets installed. Also, at the end, instead of 'sysconfdir' and 'some_datadir', transform those variables that you need. 6. If your package installs Perl scripts, also import the 'relocatable-perl' module. Then, near the beginning of each Perl script that your package installs, add the following: @relocatable_pl@ if ("@RELOCATABLE@" eq "yes") { my $exec_prefix = "@exec_prefix@"; my $orig_installdir = "@bindir@"; # see Makefile.am's *_SCRIPTS variables my ($orig_installprefix, $curr_installprefix) = find_prefixes($orig_installdir, find_curr_installdir()); sub relocate { # the subroutine is defined whether or not the enclosing block is executed my ($dir) = @_; if ("@RELOCATABLE@" eq "yes") { $dir =~ s%^$orig_installprefix/%$curr_installprefix/%; $dir =~ s,/$,,; } return $dir; } } # Get some relocated directory names. $sysconfdir = relocate("@sysconfdir@"); $some_datadir = relocate(@datadir@/something"); You must adapt the definition of '$orig_installdir', depending on where the script gets installed. Also, at the end, instead of 'sysconfdir' and 'some_datadir', transform those variables that you need. 7. In your 'Makefile.am', for every program 'foo' that gets installed in, say, '$(bindir)', you add: foo_CPPFLAGS = -DINSTALLDIR=\"$(bindir)\" if RELOCATABLE_VIA_LD foo_LDFLAGS = `$(RELOCATABLE_LDFLAGS) $(bindir)` endif 8. You may also need to add a couple of variable assignments to your 'configure.ac'. If your package (or any package you rely on, e.g. gettext-runtime) will be relocated together with a set of installed shared libraries, then set RELOCATABLE_LIBRARY_PATH to a colon-separated list of those libraries' directories, e.g. RELOCATABLE_LIBRARY_PATH='$(libdir)' If your 'config.h' is not in '$(top_builddir)', then set RELOCATABLE_CONFIG_H_DIR to its directory, e.g. RELOCATABLE_CONFIG_H_DIR='$(top_builddir)/src' 13.16 func ========== The 'func' module makes sure that you can use the predefined identifier '__func__' as defined by C99 in your code. A small example is: #include #include /* for printf */ int main (void) { printf ("%s: hello world\n", __func__); } Note that 'sizeof' cannot be applied to '__func__': On SunPRO C compiler, 'sizeof __func__' evaluates to 0. 13.17 configmake ================ The 'configmake' module builds a C include file named 'configmake.h' containing the usual installation directory values; for example, those specified by '--prefix' or '--libdir' to configure. Each variable is given a '#define' with an all-uppercase macro name, such as 'PREFIX' and 'LIBDIR'. (Automake cannot create this file directly because the user might override directory values at 'make' time.) Specifically, the module retrieves values of the variables through 'configure' followed by 'make', not directly through 'configure', so that a user who sets some of these variables consistently on the 'make' command line gets correct results. One advantage of this approach, compared to the classical approach of adding '-DLIBDIR=\"$(libdir)\"' etc. to 'AM_CPPFLAGS', is that it protects against the use of undefined variables. That is, if, say, '$(libdir)' is not set in the Makefile, 'LIBDIR' is not defined by this module, and code using 'LIBDIR' gives a compilation error. Another advantage is that 'make' output is shorter. For the complete list of variables which are '#define'd this way, see the file 'gnulib/modules/configmake', or inspect your resulting gnulib Makefile. 13.18 warnings ============== The 'warnings' module allows to regularly build a package with more GCC warnings than the default warnings emitted by GCC. It provides the following functionality: * You can select some warning options, such as '-Wall', to be enabled whenever building with a GCC version that supports these options. The user can choose to override these warning options by providing the opposite options in the 'CFLAGS' variable at configuration time. * You can make these warnings apply to selected directories only. In projects where subprojects are maintained by different people, or where parts of the source code are imported from external sources (for example from gnulib), it is useful to apply different warning options to different directories. * It lets you use '-Werror' at 'make distcheck' time, to verify that on the maintainer's system, no warnings remain. (Note that use of '-Werror' in 'CFLAGS' does not work in general, because it may break autoconfiguration.) * Similarly, it lets you use '-Werror' when the builder runs 'configure' with an option such as '--enable-gcc-warnings'. To use this module, you need the following: 1. In 'configure.ac', use for example gl_WARN_ADD([-Wall], [WARN_CFLAGS]) gl_WARN_ADD([-Wpointer-arith], [WARN_CFLAGS]) 2. In the directories which shall use 'WARN_CFLAGS', use it in the definition of 'AM_CFLAGS', like this: AM_CFLAGS = $(WARN_CFLAGS) Note that the 'AM_CFLAGS' is used in combination with 'CFLAGS' and before 'CFLAGS' in build rules emitted by Automake. This allows the user to provide 'CFLAGS' that override the 'WARN_CFLAGS'. 'gl_WARN_ADD([-Werror])' is intended for developers, and should be avoided in contexts where it would affect ordinary installation builds. The warnings emitted by GCC depend, to some extent, on the contents of the system header files, on the size and signedness of built-in types, etc. Use of '-Werror' would cause frustration to all users on platforms that the maintainer has not tested before the release. It is better if '-Werror' is off by default, and is enabled only by developers. For example, '-Werror' could affect 'make distcheck' or 'configure --enable-gcc-warnings' as mentioned above. 13.19 manywarnings ================== The 'manywarnings' module allows you to enable as many GCC warnings as possible for your package. The purpose is to protect against introducing new code that triggers warnings that weren't already triggered by the existing code base. An example use of the module is as follows: gl_MANYWARN_ALL_GCC([warnings]) # Set up the list of the pointless, undesired warnings. nw= nw="$nw -Wsystem-headers" # Don't let system headers trigger warnings nw="$nw -Wundef" # All compiler preprocessors support #if UNDEF nw="$nw -Wtraditional" # All compilers nowadays support ANSI C nw="$nw -Wconversion" # These warnings usually don't point to mistakes. nw="$nw -Wsign-conversion" # Likewise. # Enable all GCC warnings not in this list. gl_MANYWARN_COMPLEMENT([warnings], [$warnings], [$nw]) for w in $warnings; do gl_WARN_ADD([$w]) done This module is meant to be used by developers who are not very experienced regarding the various GCC warning options. In the beginning you will set the list of undesired warnings ('nw' in the example above) to empty, and compile the package with all possible warnings enabled. The GCC option '-fdiagnostics-show-option', available in GCC 4.1 or newer, helps understanding which warnings originated from which option. Then you will go through the list of warnings. You will likely deactivate warnings that occur often and don't point to mistakes in the code, by adding them to the 'nw' variable, then reconfiguring and recompiling. When warnings point to real mistakes and bugs in the code, you will of course not disable them. There are also many GCC warning options which usually don't point to mistakes in the code; these warnings enforce a certain programming style. It is a project management decision whether you want your code to follow any of these styles. Note that some of these programming styles are conflicting. You cannot have them all; you have to choose among them. When a new version of GCC is released, you can add the new warning options that it introduces into the 'gl_MANYWARN_ALL_GCC' macro (and submit your modification to the Gnulib maintainers :-)), and enjoy the benefits of the new warnings, while adding the undesired ones to the 'nw' variable. 13.20 Running self-tests under valgrind ======================================= For projects written in C or similar languages, running the self-tests under Valgrind can reveal hard to find memory issues. The 'valgrind-tests' module searches for Valgrind and declares the 'VALGRIND' automake variable for use with automake's 'TESTS_ENVIRONMENT'. After importing the 'valgrind-tests' module to your project, you use it by adding the following to the 'Makefile.am' that runs the self-tests: TESTS_ENVIRONMENT = $(VALGRIND) This will run all self-checks under valgrind. This can be wasteful if you have many shell scripts or other non-binaries. Using the Automake parallel-tests feature, this can be avoided by using the following instead: AUTOMAKE_OPTIONS = parallel-tests TEST_EXTENSIONS = .pl .sh LOG_COMPILER = $(VALGRIND) Then valgrind will only be used for the non-.sh and non-.pl tests. However, this means that binaries invoked through scripts will not be invoked under valgrind, which could be solved by adding the following: TESTS_ENVIRONMENT = VALGRIND='$(VALGRIND)' And then modify the shell scripts to invoke the binary prefixed with '$VALGRIND'. 13.21 stat-size =============== The 'stat-size' module provides a small number of macros intended for interpreting the file size information in an instance of 'struct stat'. On POSIX systems, the 'st_blocks' member of 'struct stat' contains the number of disk blocks occupied by a file. The 'ST_NBLOCKS' macro is used to estimate this quantity on systems which don't actually have 'st_blocks'. Each of these blocks contains 'ST_NBLOCKSIZE' bytes. The value of 'ST_NBLOCKSIZE' is often quite small, small enough that performing I/O in chunks that size would be inefficient. 'ST_BLKSIZE' is the I/O block size recommended for I/O to this file. This is not guaranteed to give optimum performance, but it should be reasonably efficient. 14 Regular expressions ********************** 14.1 Overview ============= A "regular expression" (or "regexp", or "pattern") is a text string that describes some (mathematical) set of strings. A regexp R "matches" a string S if S is in the set of strings described by R. Using the Regex library, you can: * see if a string matches a specified pattern as a whole, and * search within a string for a substring matching a specified pattern. Some regular expressions match only one string, i.e., the set they describe has only one member. For example, the regular expression 'foo' matches the string 'foo' and no others. Other regular expressions match more than one string, i.e., the set they describe has more than one member. For example, the regular expression 'f*' matches the set of strings made up of any number (including zero) of 'f's. As you can see, some characters in regular expressions match themselves (such as 'f') and some don't (such as '*'); the ones that don't match themselves instead let you specify patterns that describe many different strings. To either match or search for a regular expression with the Regex library functions, you must first compile it with a Regex pattern compiling function. A "compiled pattern" is a regular expression converted to the internal format used by the library functions. Once you've compiled a pattern, you can use it for matching or searching any number of times. The Regex library is used by including 'regex.h'. Regex provides three groups of functions with which you can operate on regular expressions. One group--the GNU group--is more powerful but not completely compatible with the other two, namely the POSIX and Berkeley Unix groups; its interface was designed specifically for GNU. We wrote this chapter with programmers in mind, not users of programs--such as Emacs--that use Regex. We describe the Regex library in its entirety, not how to write regular expressions that a particular program understands. 14.2 Regular Expression Syntax ============================== "Characters" are things you can type. "Operators" are things in a regular expression that match one or more characters. You compose regular expressions from operators, which in turn you specify using one or more characters. Most characters represent what we call the match-self operator, i.e., they match themselves; we call these characters "ordinary". Other characters represent either all or parts of fancier operators; e.g., '.' represents what we call the match-any-character operator (which, no surprise, matches (almost) any character); we call these characters "special". Two different things determine what characters represent what operators: 1. the regular expression syntax your program has told the Regex library to recognize, and 2. the context of the character in the regular expression. In the following sections, we describe these things in more detail. 14.2.1 Syntax Bits ------------------ In any particular syntax for regular expressions, some characters are always special, others are sometimes special, and others are never special. The particular syntax that Regex recognizes for a given regular expression depends on the current syntax (as set by 're_set_syntax') when the pattern buffer of that regular expression was compiled. You get a pattern buffer by compiling a regular expression. *Note GNU Pattern Buffers::, for more information on pattern buffers. *Note GNU Regular Expression Compiling::, and *note BSD Regular Expression Compiling::, for more information on compiling. Regex considers the current syntax to be a collection of bits; we refer to these bits as "syntax bits". In most cases, they affect what characters represent what operators. We describe the meanings of the operators to which we refer in *note Common Operators::, *note GNU Operators::, and *note GNU Emacs Operators::. For reference, here is the complete list of syntax bits, in alphabetical order: 'RE_BACKSLASH_ESCAPE_IN_LISTS' If this bit is set, then '\' inside a list (*note List Operators:: quotes (makes ordinary, if it's special) the following character; if this bit isn't set, then '\' is an ordinary character inside lists. (*Note The Backslash Character::, for what '\' does outside of lists.) 'RE_BK_PLUS_QM' If this bit is set, then '\+' represents the match-one-or-more operator and '\?' represents the match-zero-or-more operator; if this bit isn't set, then '+' represents the match-one-or-more operator and '?' represents the match-zero-or-one operator. This bit is irrelevant if 'RE_LIMITED_OPS' is set. 'RE_CHAR_CLASSES' If this bit is set, then you can use character classes in lists; if this bit isn't set, then you can't. 'RE_CONTEXT_INDEP_ANCHORS' If this bit is set, then '^' and '$' are special anywhere outside a list; if this bit isn't set, then these characters are special only in certain contexts. *Note Match-beginning-of-line Operator::, and *note Match-end-of-line Operator::. 'RE_CONTEXT_INDEP_OPS' If this bit is set, then certain characters are special anywhere outside a list; if this bit isn't set, then those characters are special only in some contexts and are ordinary elsewhere. Specifically, if this bit isn't set then '*', and (if the syntax bit 'RE_LIMITED_OPS' isn't set) '+' and '?' (or '\+' and '\?', depending on the syntax bit 'RE_BK_PLUS_QM') represent repetition operators only if they're not first in a regular expression or just after an open-group or alternation operator. The same holds for '{' (or '\{', depending on the syntax bit 'RE_NO_BK_BRACES') if it is the beginning of a valid interval and the syntax bit 'RE_INTERVALS' is set. 'RE_CONTEXT_INVALID_DUP' If this bit is set, then an open-interval operator cannot occur at the start of a regular expression, or immediately after an alternation, open-group or close-interval operator. 'RE_CONTEXT_INVALID_OPS' If this bit is set, then repetition and alternation operators can't be in certain positions within a regular expression. Specifically, the regular expression is invalid if it has: * a repetition operator first in the regular expression or just after a match-beginning-of-line, open-group, or alternation operator; or * an alternation operator first or last in the regular expression, just before a match-end-of-line operator, or just after an alternation or open-group operator. If this bit isn't set, then you can put the characters representing the repetition and alternation characters anywhere in a regular expression. Whether or not they will in fact be operators in certain positions depends on other syntax bits. 'RE_DEBUG' If this bit is set, and the regex library was compiled with '-DDEBUG', then internal debugging is turned on; if unset, then it is turned off. 'RE_DOT_NEWLINE' If this bit is set, then the match-any-character operator matches a newline; if this bit isn't set, then it doesn't. 'RE_DOT_NOT_NULL' If this bit is set, then the match-any-character operator doesn't match a null character; if this bit isn't set, then it does. 'RE_HAT_LISTS_NOT_NEWLINE' If this bit is set, nonmatching lists '[^...]' do not match newline; if not set, they do. 'RE_ICASE' If this bit is set, then ignore case when matching; otherwise, case is significant. 'RE_INTERVALS' If this bit is set, then Regex recognizes interval operators; if this bit isn't set, then it doesn't. 'RE_INVALID_INTERVAL_ORD' If this bit is set, a syntactically invalid interval is treated as a string of ordinary characters. For example, the extended regular expression 'a{1' is treated as 'a\{1'. 'RE_LIMITED_OPS' If this bit is set, then Regex doesn't recognize the match-one-or-more, match-zero-or-one or alternation operators; if this bit isn't set, then it does. 'RE_NEWLINE_ALT' If this bit is set, then newline represents the alternation operator; if this bit isn't set, then newline is ordinary. 'RE_NO_BK_BRACES' If this bit is set, then '{' represents the open-interval operator and '}' represents the close-interval operator; if this bit isn't set, then '\{' represents the open-interval operator and '\}' represents the close-interval operator. This bit is relevant only if 'RE_INTERVALS' is set. 'RE_NO_BK_PARENS' If this bit is set, then '(' represents the open-group operator and ')' represents the close-group operator; if this bit isn't set, then '\(' represents the open-group operator and '\)' represents the close-group operator. 'RE_NO_BK_REFS' If this bit is set, then Regex doesn't recognize '\'DIGIT as the back reference operator; if this bit isn't set, then it does. 'RE_NO_BK_VBAR' If this bit is set, then '|' represents the alternation operator; if this bit isn't set, then '\|' represents the alternation operator. This bit is irrelevant if 'RE_LIMITED_OPS' is set. 'RE_NO_EMPTY_RANGES' If this bit is set, then a regular expression with a range whose ending point collates lower than its starting point is invalid; if this bit isn't set, then Regex considers such a range to be empty. 'RE_NO_GNU_OPS' If this bit is set, GNU regex operators are not recognized; otherwise, they are. 'RE_NO_POSIX_BACKTRACKING' If this bit is set, succeed as soon as we match the whole pattern, without further backtracking. This means that a match may not be the leftmost longest; *note What Gets Matched?:: for what this means. 'RE_NO_SUB' If this bit is set, then 'no_sub' will be set to one during 're_compile_pattern'. This causes matching and searching routines not to record substring match information. 'RE_UNMATCHED_RIGHT_PAREN_ORD' If this bit is set and the regular expression has no matching open-group operator, then Regex considers what would otherwise be a close-group operator (based on how 'RE_NO_BK_PARENS' is set) to match ')'. 14.2.2 Predefined Syntaxes -------------------------- If you're programming with Regex, you can set a pattern buffer's (*note GNU Pattern Buffers::) syntax either to an arbitrary combination of syntax bits (*note Syntax Bits::) or else to the configurations defined by Regex. These configurations define the syntaxes used by certain programs--GNU Emacs, POSIX Awk, traditional Awk, Grep, Egrep--in addition to syntaxes for POSIX basic and extended regular expressions. The predefined syntaxes--taken directly from 'regex.h'--are: #define RE_SYNTAX_EMACS 0 #define RE_SYNTAX_AWK \ (RE_BACKSLASH_ESCAPE_IN_LISTS | RE_DOT_NOT_NULL \ | RE_NO_BK_PARENS | RE_NO_BK_REFS \ | RE_NO_BK_VBAR | RE_NO_EMPTY_RANGES \ | RE_UNMATCHED_RIGHT_PAREN_ORD) #define RE_SYNTAX_POSIX_AWK \ (RE_SYNTAX_POSIX_EXTENDED | RE_BACKSLASH_ESCAPE_IN_LISTS) #define RE_SYNTAX_GREP \ (RE_BK_PLUS_QM | RE_CHAR_CLASSES \ | RE_HAT_LISTS_NOT_NEWLINE | RE_INTERVALS \ | RE_NEWLINE_ALT) #define RE_SYNTAX_EGREP \ (RE_CHAR_CLASSES | RE_CONTEXT_INDEP_ANCHORS \ | RE_CONTEXT_INDEP_OPS | RE_HAT_LISTS_NOT_NEWLINE \ | RE_NEWLINE_ALT | RE_NO_BK_PARENS \ | RE_NO_BK_VBAR) #define RE_SYNTAX_POSIX_EGREP \ (RE_SYNTAX_EGREP | RE_INTERVALS | RE_NO_BK_BRACES) /* P1003.2/D11.2, section 4.20.7.1, lines 5078ff. */ #define RE_SYNTAX_ED RE_SYNTAX_POSIX_BASIC #define RE_SYNTAX_SED RE_SYNTAX_POSIX_BASIC /* Syntax bits common to both basic and extended POSIX regex syntax. */ #define _RE_SYNTAX_POSIX_COMMON \ (RE_CHAR_CLASSES | RE_DOT_NEWLINE | RE_DOT_NOT_NULL \ | RE_INTERVALS | RE_NO_EMPTY_RANGES) #define RE_SYNTAX_POSIX_BASIC \ (_RE_SYNTAX_POSIX_COMMON | RE_BK_PLUS_QM) /* Differs from ..._POSIX_BASIC only in that RE_BK_PLUS_QM becomes RE_LIMITED_OPS, i.e., \? \+ \| are not recognized.

It defines a "collating element" to be "a sequence of one or more bytes defined in the current collating sequence as a unit of collation." This generalizes the notion of a character in two ways. First, a single character can map into two or more collating elements. For example, the German "es-zet" collates as the collating element 's' followed by another collating element 's'. Second, two or more characters can map into one collating element. For example, the Spanish 'll' collates after 'l' and before 'm'. Since POSIX's "collating element" preserves the essential idea of a "character," we use the latter, more familiar, term in this document. 14.2.4 The Backslash Character ------------------------------ The '\' character has one of four different meanings, depending on the context in which you use it and what syntax bits are set (*note Syntax Bits::). It can: 1) stand for itself, 2) quote the next character, 3) introduce an operator, or 4) do nothing. 1. It stands for itself inside a list (*note List Operators::) if the syntax bit 'RE_BACKSLASH_ESCAPE_IN_LISTS' is not set. For example, '[\]' would match '\'. 2. It quotes (makes ordinary, if it's special) the next character when you use it either: * outside a list,(1) or * inside a list and the syntax bit 'RE_BACKSLASH_ESCAPE_IN_LISTS' is set. 3. It introduces an operator when followed by certain ordinary characters--sometimes only when certain syntax bits are set. See the cases 'RE_BK_PLUS_QM', 'RE_NO_BK_BRACES', 'RE_NO_BK_VAR', 'RE_NO_BK_PARENS', 'RE_NO_BK_REF' in *note Syntax Bits::. Also: * '\b' represents the match-word-boundary operator (*note Match-word-boundary Operator::). * '\B' represents the match-within-word operator (*note Match-within-word Operator::). * '\<' represents the match-beginning-of-word operator (*note Match-beginning-of-word Operator::). * '\>' represents the match-end-of-word operator (*note Match-end-of-word Operator::). * '\w' represents the match-word-constituent operator (*note Match-word-constituent Operator::). * '\W' represents the match-non-word-constituent operator (*note Match-non-word-constituent Operator::). * '\`' represents the match-beginning-of-buffer operator and '\'' represents the match-end-of-buffer operator (*note Buffer Operators::). * If Regex was compiled with the C preprocessor symbol 'emacs' defined, then '\sCLASS' represents the match-syntactic-class operator and '\SCLASS' represents the match-not-syntactic-class operator (*note Syntactic Class Operators::). 4. In all other cases, Regex ignores '\'. For example, '\n' matches 'n'. ---------- Footnotes ---------- (1) Sometimes you don't have to explicitly quote special characters to make them ordinary. For instance, most characters lose any special meaning inside a list (*note List Operators::). In addition, if the syntax bits 'RE_CONTEXT_INVALID_OPS' and 'RE_CONTEXT_INDEP_OPS' aren't set, then (for historical reasons) the matcher considers special characters ordinary if they are in contexts where the operations they represent make no sense; for example, then the match-zero-or-more operator (represented by '*') matches itself in the regular expression '*foo' because there is no preceding expression on which it can operate. It is poor practice, however, to depend on this behavior; if you want a special character to be ordinary outside a list, it's better to always quote it, regardless. 14.3 Common Operators ===================== You compose regular expressions from operators. In the following sections, we describe the regular expression operators specified by POSIX; GNU also uses these. Most operators have more than one representation as characters. *Note Regular Expression Syntax::, for what characters represent what operators under what circumstances. For most operators that can be represented in two ways, one representation is a single character and the other is that character preceded by '\'. For example, either '(' or '\(' represents the open-group operator. Which one does depends on the setting of a syntax bit, in this case 'RE_NO_BK_PARENS'. Why is this so? Historical reasons dictate some of the varying representations, while POSIX dictates others. Finally, almost all characters lose any special meaning inside a list (*note List Operators::). 14.3.1 The Match-self Operator (ORDINARY CHARACTER) --------------------------------------------------- This operator matches the character itself. All ordinary characters (*note Regular Expression Syntax::) represent this operator. For example, 'f' is always an ordinary character, so the regular expression 'f' matches only the string 'f'. In particular, it does _not_ match the string 'ff'. 14.3.2 The Match-any-character Operator ('.') --------------------------------------------- This operator matches any single printing or nonprinting character except it won't match a: newline if the syntax bit 'RE_DOT_NEWLINE' isn't set. null if the syntax bit 'RE_DOT_NOT_NULL' is set. The '.' (period) character represents this operator. For example, 'a.b' matches any three-character string beginning with 'a' and ending with 'b'. 14.3.3 The Concatenation Operator --------------------------------- This operator concatenates two regular expressions A and B. No character represents this operator; you simply put B after A. The result is a regular expression that will match a string if A matches its first part and B matches the rest. For example, 'xy' (two match-self operators) matches 'xy'. 14.3.4 Repetition Operators --------------------------- Repetition operators repeat the preceding regular expression a specified number of times. 14.3.4.1 The Match-zero-or-more Operator ('*') .............................................. This operator repeats the smallest possible preceding regular expression as many times as necessary (including zero) to match the pattern. '*' represents this operator. For example, 'o*' matches any string made up of zero or more 'o's. Since this operator operates on the smallest preceding regular expression, 'fo*' has a repeating 'o', not a repeating 'fo'. So, 'fo*' matches 'f', 'fo', 'foo', and so on. Since the match-zero-or-more operator is a suffix operator, it may be useless as such when no regular expression precedes it. This is the case when it: * is first in a regular expression, or * follows a match-beginning-of-line, open-group, or alternation operator. Three different things can happen in these cases: 1. If the syntax bit 'RE_CONTEXT_INVALID_OPS' is set, then the regular expression is invalid. 2. If 'RE_CONTEXT_INVALID_OPS' isn't set, but 'RE_CONTEXT_INDEP_OPS' is, then '*' represents the match-zero-or-more operator (which then operates on the empty string). 3. Otherwise, '*' is ordinary. The matcher processes a match-zero-or-more operator by first matching as many repetitions of the smallest preceding regular expression as it can. Then it continues to match the rest of the pattern. If it can't match the rest of the pattern, it backtracks (as many times as necessary), each time discarding one of the matches until it can either match the entire pattern or be certain that it cannot get a match. For example, when matching 'ca*ar' against 'caaar', the matcher first matches all three 'a's of the string with the 'a*' of the regular expression. However, it cannot then match the final 'ar' of the regular expression against the final 'r' of the string. So it backtracks, discarding the match of the last 'a' in the string. It can then match the remaining 'ar'. 14.3.4.2 The Match-one-or-more Operator ('+' or '\+') ..................................................... If the syntax bit 'RE_LIMITED_OPS' is set, then Regex doesn't recognize this operator. Otherwise, if the syntax bit 'RE_BK_PLUS_QM' isn't set, then '+' represents this operator; if it is, then '\+' does. This operator is similar to the match-zero-or-more operator except that it repeats the preceding regular expression at least once; *note Match-zero-or-more Operator::, for what it operates on, how some syntax bits affect it, and how Regex backtracks to match it. For example, supposing that '+' represents the match-one-or-more operator; then 'ca+r' matches, e.g., 'car' and 'caaaar', but not 'cr'. 14.3.4.3 The Match-zero-or-one Operator ('?' or '\?') ..................................................... If the syntax bit 'RE_LIMITED_OPS' is set, then Regex doesn't recognize this operator. Otherwise, if the syntax bit 'RE_BK_PLUS_QM' isn't set, then '?' represents this operator; if it is, then '\?' does. This operator is similar to the match-zero-or-more operator except that it repeats the preceding regular expression once or not at all; *note Match-zero-or-more Operator::, to see what it operates on, how some syntax bits affect it, and how Regex backtracks to match it. For example, supposing that '?' represents the match-zero-or-one operator; then 'ca?r' matches both 'car' and 'cr', but nothing else. 14.3.4.4 Interval Operators ('{' ... '}' or '\{' ... '\}') .......................................................... If the syntax bit 'RE_INTERVALS' is set, then Regex recognizes "interval expressions". They repeat the smallest possible preceding regular expression a specified number of times. If the syntax bit 'RE_NO_BK_BRACES' is set, '{' represents the "open-interval operator" and '}' represents the "close-interval operator" ; otherwise, '\{' and '\}' do. Specifically, supposing that '{' and '}' represent the open-interval and close-interval operators; then: '{COUNT}' matches exactly COUNT occurrences of the preceding regular expression. '{MIN,}' matches MIN or more occurrences of the preceding regular expression. '{MIN, MAX}' matches at least MIN but no more than MAX occurrences of the preceding regular expression. The interval expression (but not necessarily the regular expression that contains it) is invalid if: * MIN is greater than MAX, or * any of COUNT, MIN, or MAX are outside the range zero to 'RE_DUP_MAX' (which symbol 'regex.h' defines). If the interval expression is invalid and the syntax bit 'RE_NO_BK_BRACES' is set, then Regex considers all the characters in the would-be interval to be ordinary. If that bit isn't set, then the regular expression is invalid. If the interval expression is valid but there is no preceding regular expression on which to operate, then if the syntax bit 'RE_CONTEXT_INVALID_OPS' is set, the regular expression is invalid. If that bit isn't set, then Regex considers all the characters--other than backslashes, which it ignores--in the would-be interval to be ordinary. 14.3.5 The Alternation Operator ('|' or '\|') --------------------------------------------- If the syntax bit 'RE_LIMITED_OPS' is set, then Regex doesn't recognize this operator. Otherwise, if the syntax bit 'RE_NO_BK_VBAR' is set, then '|' represents this operator; otherwise, '\|' does. Alternatives match one of a choice of regular expressions: if you put the character(s) representing the alternation operator between any two regular expressions A and B, the result matches the union of the strings that A and B match. For example, supposing that '|' is the alternation operator, then 'foo|bar|quux' would match any of 'foo', 'bar' or 'quux'. The alternation operator operates on the _largest_ possible surrounding regular expressions. (Put another way, it has the lowest precedence of any regular expression operator.) Thus, the only way you can delimit its arguments is to use grouping. For example, if '(' and ')' are the open and close-group operators, then 'fo(o|b)ar' would match either 'fooar' or 'fobar'. ('foo|bar' would match 'foo' or 'bar'.) The matcher usually tries all combinations of alternatives so as to match the longest possible string. For example, when matching '(fooq|foo)*(qbarquux|bar)' against 'fooqbarquux', it cannot take, say, the first ("depth-first") combination it could match, since then it would be content to match just 'fooqbar'. Note that since the default behavior is to return the leftmost longest match, when more than one of a series of alternatives matches the actual match will be the longest matching alternative, not necessarily the first in the list. 14.3.6 List Operators ('[' ... ']' and '[^' ... ']') ---------------------------------------------------- "Lists", also called "bracket expressions", are a set of one or more items. An "item" is a character, a collating symbol, an equivalence class expression, a character class expression, or a range expression. The syntax bits affect which kinds of items you can put in a list. We explain the last four items in subsections below. Empty lists are invalid. A "matching list" matches a single character represented by one of the list items. You form a matching list by enclosing one or more items within an "open-matching-list operator" (represented by '[') and a "close-list operator" (represented by ']'). For example, '[ab]' matches either 'a' or 'b'. '[ad]*' matches the empty string and any string composed of just 'a's and 'd's in any order. Regex considers invalid a regular expression with a '[' but no matching ']'. "Nonmatching lists" are similar to matching lists except that they match a single character _not_ represented by one of the list items. You use an "open-nonmatching-list operator" (represented by '[^'(1)) instead of an open-matching-list operator to start a nonmatching list. For example, '[^ab]' matches any character except 'a' or 'b'. If the syntax bit 'RE_HAT_LISTS_NOT_NEWLINE' is set, then nonmatching lists do not match a newline. Most characters lose any special meaning inside a list. The special characters inside a list follow. ']' ends the list if it's not the first list item. So, if you want to make the ']' character a list item, you must put it first. '\' quotes the next character if the syntax bit 'RE_BACKSLASH_ESCAPE_IN_LISTS' is set. '[.' represents the open-collating-symbol operator (*note Collating Symbol Operators::). '.]' represents the close-collating-symbol operator. '[=' represents the open-equivalence-class operator (*note Equivalence Class Operators::). '=]' represents the close-equivalence-class operator. '[:' represents the open-character-class operator (*note Character Class Operators::) if the syntax bit 'RE_CHAR_CLASSES' is set and what follows is a valid character class expression. ':]' represents the close-character-class operator if the syntax bit 'RE_CHAR_CLASSES' is set and what precedes it is an open-character-class operator followed by a valid character class name. '-' represents the range operator (*note Range Operator::) if it's not first or last in a list or the ending point of a range. All other characters are ordinary. For example, '[.*]' matches '.' and '*'. ---------- Footnotes ---------- (1) Regex therefore doesn't consider the '^' to be the first character in the list. If you put a '^' character first in (what you think is) a matching list, you'll turn it into a nonmatching list. 14.3.6.1 Collating Symbol Operators ('[.' ... '.]') ................................................... Collating symbols can be represented inside lists. You form a "collating symbol" by putting a collating element between an "open-collating-symbol operator" and a "close-collating-symbol operator". '[.' represents the open-collating-symbol operator and '.]' represents the close-collating-symbol operator. For example, if 'll' is a collating element, then '[[.ll.]]' would match 'll'. 14.3.6.2 Equivalence Class Operators ('[=' ... '=]') .................................................... Regex recognizes equivalence class expressions inside lists. A "equivalence class expression" is a set of collating elements which all belong to the same equivalence class. You form an equivalence class expression by putting a collating element between an "open-equivalence-class operator" and a "close-equivalence-class operator". '[=' represents the open-equivalence-class operator and '=]' represents the close-equivalence-class operator. For example, if 'a' and 'A' were an equivalence class, then both '[[=a=]]' and '[[=A=]]' would match both 'a' and 'A'. If the collating element in an equivalence class expression isn't part of an equivalence class, then the matcher considers the equivalence class expression to be a collating symbol. 14.3.6.3 Character Class Operators ('[:' ... ':]') .................................................. If the syntax bit 'RE_CHAR_CLASSES' is set, then Regex recognizes character class expressions inside lists. A "character class expression" matches one character from a given class. You form a character class expression by putting a character class name between an "open-character-class operator" (represented by '[:') and a "close-character-class operator" (represented by ':]'). The character class names and their meanings are: 'alnum' letters and digits 'alpha' letters 'blank' system-dependent; for GNU, a space or tab 'cntrl' control characters (in the ASCII encoding, code 0177 and codes less than 040) 'digit' digits 'graph' same as 'print' except omits space 'lower' lowercase letters 'print' printable characters (in the ASCII encoding, space tilde--codes 040 through 0176) 'punct' neither control nor alphanumeric characters 'space' space, carriage return, newline, vertical tab, and form feed 'upper' uppercase letters 'xdigit' hexadecimal digits: '0'-'9', 'a'-'f', 'A'-'F' These correspond to the definitions in the C library's '' facility. For example, '[:alpha:]' corresponds to the standard facility 'isalpha'. Regex recognizes character class expressions only inside of lists; so '[[:alpha:]]' matches any letter, but '[:alpha:]' outside of a bracket expression and not followed by a repetition operator matches just itself. 14.3.6.4 The Range Operator ('-') ................................. Regex recognizes "range expressions" inside a list. They represent those characters that fall between two elements in the current collating sequence. You form a range expression by putting a "range operator" between two of any of the following: characters, collating elements, collating symbols, and equivalence class expressions. The starting point of the range and the ending point of the range don't have to be the same kind of item, e.g., the starting point could be a collating element and the ending point could be an equivalence class expression. If a range's ending point is an equivalence class, then all the collating elements in that class will be in the range.(1) '-' represents the range operator. For example, 'a-f' within a list represents all the characters from 'a' through 'f' inclusively. If the syntax bit 'RE_NO_EMPTY_RANGES' is set, then if the range's ending point collates less than its starting point, the range (and the regular expression containing it) is invalid. For example, the regular expression '[z-a]' would be invalid. If this bit isn't set, then Regex considers such a range to be empty. Since '-' represents the range operator, if you want to make a '-' character itself a list item, you must do one of the following: * Put the '-' either first or last in the list. * Include a range whose starting point collates strictly lower than '-' and whose ending point collates equal or higher. Unless a range is the first item in a list, a '-' can't be its starting point, but _can_ be its ending point. That is because Regex considers '-' to be the range operator unless it is preceded by another '-'. For example, in the ASCII encoding, ')', '*', '+', ',', '-', '.', and '/' are contiguous characters in the collating sequence. You might think that '[)-+--/]' has two ranges: ')-+' and '--/'. Rather, it has the ranges ')-+' and '+--', plus the character '/', so it matches, e.g., ',', not '.'. * Put a range whose starting point is '-' first in the list. For example, '[-a-z]' matches a lowercase letter or a hyphen (in English, in ASCII). ---------- Footnotes ---------- (1) You can't use a character class for the starting or ending point of a range, since a character class is not a single character. 14.3.7 Grouping Operators ('(' ... ')' or '\(' ... '\)') -------------------------------------------------------- A "group", also known as a "subexpression", consists of an "open-group operator", any number of other operators, and a "close-group operator". Regex treats this sequence as a unit, just as mathematics and programming languages treat a parenthesized expression as a unit. Therefore, using "groups", you can: * delimit the argument(s) to an alternation operator (*note Alternation Operator::) or a repetition operator (*note Repetition Operators::). * keep track of the indices of the substring that matched a given group. *Note Using Registers::, for a precise explanation. This lets you: * use the back-reference operator (*note Back-reference Operator::). * use registers (*note Using Registers::). If the syntax bit 'RE_NO_BK_PARENS' is set, then '(' represents the open-group operator and ')' represents the close-group operator; otherwise, '\(' and '\)' do. If the syntax bit 'RE_UNMATCHED_RIGHT_PAREN_ORD' is set and a close-group operator has no matching open-group operator, then Regex considers it to match ')'. 14.3.8 The Back-reference Operator ("\"DIGIT) --------------------------------------------- If the syntax bit 'RE_NO_BK_REF' isn't set, then Regex recognizes back references. A back reference matches a specified preceding group. The back reference operator is represented by '\DIGIT' anywhere after the end of a regular expression's DIGIT-th group (*note Grouping Operators::). DIGIT must be between '1' and '9'. The matcher assigns numbers 1 through 9 to the first nine groups it encounters. By using one of '\1' through '\9' after the corresponding group's close-group operator, you can match a substring identical to the one that the group does. Back references match according to the following (in all examples below, '(' represents the open-group, ')' the close-group, '{' the open-interval and '}' the close-interval operator): * If the group matches a substring, the back reference matches an identical substring. For example, '(a)\1' matches 'aa' and '(bana)na\1bo\1' matches 'bananabanabobana'. Likewise, '(.*)\1' matches any (newline-free if the syntax bit 'RE_DOT_NEWLINE' isn't set) string that is composed of two identical halves; the '(.*)' matches the first half and the '\1' matches the second half. * If the group matches more than once (as it might if followed by, e.g., a repetition operator), then the back reference matches the substring the group _last_ matched. For example, '((a*)b)*\1\2' matches 'aabababa'; first group 1 (the outer one) matches 'aab' and group 2 (the inner one) matches 'aa'. Then group 1 matches 'ab' and group 2 matches 'a'. So, '\1' matches 'ab' and '\2' matches 'a'. * If the group doesn't participate in a match, i.e., it is part of an alternative not taken or a repetition operator allows zero repetitions of it, then the back reference makes the whole match fail. For example, '(one()|two())-and-(three\2|four\3)' matches 'one-and-three' and 'two-and-four', but not 'one-and-four' or 'two-and-three'. For example, if the pattern matches 'one-and-', then its group 2 matches the empty string and its group 3 doesn't participate in the match. So, if it then matches 'four', then when it tries to back reference group 3--which it will attempt to do because '\3' follows the 'four'--the match will fail because group 3 didn't participate in the match. You can use a back reference as an argument to a repetition operator. For example, '(a(b))\2*' matches 'a' followed by two or more 'b's. Similarly, '(a(b))\2{3}' matches 'abbbb'. If there is no preceding DIGIT-th subexpression, the regular expression is invalid. 14.3.9 Anchoring Operators -------------------------- These operators can constrain a pattern to match only at the beginning or end of the entire string or at the beginning or end of a line. 14.3.9.1 The Match-beginning-of-line Operator ('^') ................................................... This operator can match the empty string either at the beginning of the string or after a newline character. Thus, it is said to "anchor" the pattern to the beginning of a line. In the cases following, '^' represents this operator. (Otherwise, '^' is ordinary.) * It (the '^') is first in the pattern, as in '^foo'. * The syntax bit 'RE_CONTEXT_INDEP_ANCHORS' is set, and it is outside a bracket expression. * It follows an open-group or alternation operator, as in 'a\(^b\)' and 'a\|^b'. *Note Grouping Operators::, and *note Alternation Operator::. These rules imply that some valid patterns containing '^' cannot be matched; for example, 'foo^bar' if 'RE_CONTEXT_INDEP_ANCHORS' is set. If the 'not_bol' field is set in the pattern buffer (*note GNU Pattern Buffers::), then '^' fails to match at the beginning of the string. This lets you match against pieces of a line, as you would need to if, say, searching for repeated instances of a given pattern in a line; it would work correctly for patterns both with and without match-beginning-of-line operators. 14.3.9.2 The Match-end-of-line Operator ('$') ............................................. This operator can match the empty string either at the end of the string or before a newline character in the string. Thus, it is said to "anchor" the pattern to the end of a line. It is always represented by '$'. For example, 'foo$' usually matches, e.g., 'foo' and, e.g., the first three characters of 'foo\nbar'. Its interaction with the syntax bits and pattern buffer fields is exactly the dual of '^''s; see the previous section. (That is, "'^'" becomes "'$'", "beginning" becomes "end", "next" becomes "previous", "after" becomes "before", and "'not_bol'" becomes "'not_eol'".) 14.4 GNU Operators ================== Following are operators that GNU defines (and POSIX doesn't). 14.4.1 Word Operators --------------------- The operators in this section require Regex to recognize parts of words. Regex uses a syntax table to determine whether or not a character is part of a word, i.e., whether or not it is "word-constituent". 14.4.1.1 Non-Emacs Syntax Tables ................................ A "syntax table" is an array indexed by the characters in your character set. In the ASCII encoding, therefore, a syntax table has 256 elements. Regex always uses a 'char *' variable 're_syntax_table' as its syntax table. In some cases, it initializes this variable and in others it expects you to initialize it. * If Regex is compiled with the preprocessor symbols 'emacs' and 'SYNTAX_TABLE' both undefined, then Regex allocates 're_syntax_table' and initializes an element I either to 'Sword' (which it defines) if I is a letter, number, or '_', or to zero if it's not. * If Regex is compiled with 'emacs' undefined but 'SYNTAX_TABLE' defined, then Regex expects you to define a 'char *' variable 're_syntax_table' to be a valid syntax table. * *Note Emacs Syntax Tables::, for what happens when Regex is compiled with the preprocessor symbol 'emacs' defined. 14.4.1.2 The Match-word-boundary Operator ('\b') ................................................ This operator (represented by '\b') matches the empty string at either the beginning or the end of a word. For example, '\brat\b' matches the separate word 'rat'. 14.4.1.3 The Match-within-word Operator ('\B') .............................................. This operator (represented by '\B') matches the empty string within a word. For example, 'c\Brat\Be' matches 'crate', but 'dirty \Brat' doesn't match 'dirty rat'. 14.4.1.4 The Match-beginning-of-word Operator ('\<') .................................................... This operator (represented by '\<') matches the empty string at the beginning of a word. 14.4.1.5 The Match-end-of-word Operator ('\>') .............................................. This operator (represented by '\>') matches the empty string at the end of a word. 14.4.1.6 The Match-word-constituent Operator ('\w') ................................................... This operator (represented by '\w') matches any word-constituent character. 14.4.1.7 The Match-non-word-constituent Operator ('\W') ....................................................... This operator (represented by '\W') matches any character that is not word-constituent. 14.4.2 Buffer Operators ----------------------- Following are operators which work on buffers. In Emacs, a "buffer" is, naturally, an Emacs buffer. For other programs, Regex considers the entire string to be matched as the buffer. 14.4.2.1 The Match-beginning-of-buffer Operator ('\`') ...................................................... This operator (represented by '\`') matches the empty string at the beginning of the buffer. 14.4.2.2 The Match-end-of-buffer Operator ('\'') ................................................ This operator (represented by '\'') matches the empty string at the end of the buffer. 14.5 GNU Emacs Operators ======================== Following are operators that GNU defines (and POSIX doesn't) that you can use only when Regex is compiled with the preprocessor symbol 'emacs' defined. 14.5.1 Syntactic Class Operators -------------------------------- The operators in this section require Regex to recognize the syntactic classes of characters. Regex uses a syntax table to determine this. 14.5.1.1 Emacs Syntax Tables ............................ A "syntax table" is an array indexed by the characters in your character set. In the ASCII encoding, therefore, a syntax table has 256 elements. If Regex is compiled with the preprocessor symbol 'emacs' defined, then Regex expects you to define and initialize the variable 're_syntax_table' to be an Emacs syntax table. Emacs' syntax tables are more complicated than Regex's own (*note Non-Emacs Syntax Tables::). *Note Syntax: (emacs)Syntax, for a description of Emacs' syntax tables. 14.5.1.2 The Match-syntactic-class Operator ('\s'CLASS) ....................................................... This operator matches any character whose syntactic class is represented by a specified character. '\sCLASS' represents this operator where CLASS is the character representing the syntactic class you want. For example, 'w' represents the syntactic class of word-constituent characters, so '\sw' matches any word-constituent character. 14.5.1.3 The Match-not-syntactic-class Operator ('\S'CLASS) ........................................................... This operator is similar to the match-syntactic-class operator except that it matches any character whose syntactic class is _not_ represented by the specified character. '\SCLASS' represents this operator. For example, 'w' represents the syntactic class of word-constituent characters, so '\Sw' matches any character that is not word-constituent. 14.6 What Gets Matched? ======================= Regex usually matches strings according to the "leftmost longest" rule; that is, it chooses the longest of the leftmost matches. This does not mean that for a regular expression containing subexpressions that it simply chooses the longest match for each subexpression, left to right; the overall match must also be the longest possible one. For example, '(ac*)(c*d[ac]*)\1' matches 'acdacaaa', not 'acdac', as it would if it were to choose the longest match for the first subexpression. 14.7 Programming with Regex =========================== Here we describe how you use the Regex data structures and functions in C programs. Regex has three interfaces: one designed for GNU, one compatible with POSIX (as specified by POSIX, draft 1003.2/D11.2), and one compatible with Berkeley Unix. The POSIX interface is not documented here; see the documentation of GNU libc, or the POSIX man pages. The Berkeley Unix interface is documented here for convenience, since its documentation is not otherwise readily available on GNU systems. 14.7.1 GNU Regex Functions -------------------------- If you're writing code that doesn't need to be compatible with either POSIX or Berkeley Unix, you can use these functions. They provide more options than the other interfaces. 14.7.1.1 GNU Pattern Buffers ............................ To compile, match, or search for a given regular expression, you must supply a pattern buffer. A "pattern buffer" holds one compiled regular expression.(1) You can have several different pattern buffers simultaneously, each holding a compiled pattern for a different regular expression. 'regex.h' defines the pattern buffer 'struct' with the following public fields: unsigned char *buffer; unsigned long allocated; char *fastmap; char *translate; size_t re_nsub; unsigned no_sub : 1; unsigned not_bol : 1; unsigned not_eol : 1; ---------- Footnotes ---------- (1) Regular expressions are also referred to as "patterns," hence the name "pattern buffer." 14.7.1.2 GNU Regular Expression Compiling ......................................... In GNU, you can both match and search for a given regular expression. To do either, you must first compile it in a pattern buffer (*note GNU Pattern Buffers::). Regular expressions match according to the syntax with which they were compiled; with GNU, you indicate what syntax you want by setting the variable 're_syntax_options' (declared in 'regex.h') before calling the compiling function, 're_compile_pattern' (see below). *Note Syntax Bits::, and *note Predefined Syntaxes::. You can change the value of 're_syntax_options' at any time. Usually, however, you set its value once and then never change it. 're_compile_pattern' takes a pattern buffer as an argument. You must initialize the following fields: 'translate initialization' 'translate' Initialize this to point to a translate table if you want one, or to zero if you don't. We explain translate tables in *note GNU Translate Tables::. 'fastmap' Initialize this to nonzero if you want a fastmap, or to zero if you don't. 'buffer' 'allocated' If you want 're_compile_pattern' to allocate memory for the compiled pattern, set both of these to zero. If you have an existing block of memory (allocated with 'malloc') you want Regex to use, set 'buffer' to its address and 'allocated' to its size (in bytes). 're_compile_pattern' uses 'realloc' to extend the space for the compiled pattern as necessary. To compile a pattern buffer, use: char * re_compile_pattern (const char *REGEX, const int REGEX_SIZE, struct re_pattern_buffer *PATTERN_BUFFER) REGEX is the regular expression's address, REGEX_SIZE is its length, and PATTERN_BUFFER is the pattern buffer's address. If 're_compile_pattern' successfully compiles the regular expression, it returns zero and sets '*PATTERN_BUFFER' to the compiled pattern. It sets the pattern buffer's fields as follows: 'buffer' to the compiled pattern. 'syntax' to the current value of 're_syntax_options'. 're_nsub' to the number of subexpressions in REGEX. If 're_compile_pattern' can't compile REGEX, it returns an error string corresponding to a POSIX error code. 14.7.1.3 GNU Matching ..................... Matching the GNU way means trying to match as much of a string as possible starting at a position within it you specify. Once you've compiled a pattern into a pattern buffer (*note GNU Regular Expression Compiling::), you can ask the matcher to match that pattern against a string using: int re_match (struct re_pattern_buffer *PATTERN_BUFFER, const char *STRING, const int SIZE, const int START, struct re_registers *REGS) PATTERN_BUFFER is the address of a pattern buffer containing a compiled pattern. STRING is the string you want to match; it can contain newline and null characters. SIZE is the length of that string. START is the string index at which you want to begin matching; the first character of STRING is at index zero. *Note Using Registers::, for an explanation of REGS; you can safely pass zero. 're_match' matches the regular expression in PATTERN_BUFFER against the string STRING according to the syntax of PATTERN_BUFFER. (*Note GNU Regular Expression Compiling::, for how to set it.) The function returns -1 if the compiled pattern does not match any part of STRING and -2 if an internal error happens; otherwise, it returns how many (possibly zero) characters of STRING the pattern matched. An example: suppose PATTERN_BUFFER points to a pattern buffer containing the compiled pattern for 'a*', and STRING points to 'aaaaab' (whereupon SIZE should be 6). Then if START is 2, 're_match' returns 3, i.e., 'a*' would have matched the last three 'a's in STRING. If START is 0, 're_match' returns 5, i.e., 'a*' would have matched all the 'a's in STRING. If START is either 5 or 6, it returns zero. If START is not between zero and SIZE, then 're_match' returns -1. 14.7.1.4 GNU Searching ...................... "Searching" means trying to match starting at successive positions within a string. The function 're_search' does this. Before calling 're_search', you must compile your regular expression. *Note GNU Regular Expression Compiling::. Here is the function declaration: int re_search (struct re_pattern_buffer *PATTERN_BUFFER, const char *STRING, const int SIZE, const int START, const int RANGE, struct re_registers *REGS) whose arguments are the same as those to 're_match' (*note GNU Matching::) except that the two arguments START and RANGE replace 're_match''s argument START. If RANGE is positive, then 're_search' attempts a match starting first at index START, then at START + 1 if that fails, and so on, up to START + RANGE; if RANGE is negative, then it attempts a match starting first at index START, then at START -1 if that fails, and so on. If START is not between zero and SIZE, then 're_search' returns -1. When RANGE is positive, 're_search' adjusts RANGE so that START + RANGE - 1 is between zero and SIZE, if necessary; that way it won't search outside of STRING. Similarly, when RANGE is negative, 're_search' adjusts RANGE so that START + RANGE + 1 is between zero and SIZE, if necessary. If the 'fastmap' field of PATTERN_BUFFER is zero, 're_search' matches starting at consecutive positions; otherwise, it uses 'fastmap' to make the search more efficient. *Note Searching with Fastmaps::. If no match is found, 're_search' returns -1. If a match is found, it returns the index where the match began. If an internal error happens, it returns -2. 14.7.1.5 Matching and Searching with Split Data ............................................... Using the functions 're_match_2' and 're_search_2', you can match or search in data that is divided into two strings. The function: int re_match_2 (struct re_pattern_buffer *BUFFER, const char *STRING1, const int SIZE1, const char *STRING2, const int SIZE2, const int START, struct re_registers *REGS, const int STOP) is similar to 're_match' (*note GNU Matching::) except that you pass _two_ data strings and sizes, and an index STOP beyond which you don't want the matcher to try matching. As with 're_match', if it succeeds, 're_match_2' returns how many characters of STRING it matched. Regard STRING1 and STRING2 as concatenated when you set the arguments START and STOP and use the contents of REGS; 're_match_2' never returns a value larger than SIZE1 + SIZE2. The function: int re_search_2 (struct re_pattern_buffer *BUFFER, const char *STRING1, const int SIZE1, const char *STRING2, const int SIZE2, const int START, const int RANGE, struct re_registers *REGS, const int STOP) is similarly related to 're_search'. 14.7.1.6 Searching with Fastmaps ................................ If you're searching through a long string, you should use a fastmap. Without one, the searcher tries to match at consecutive positions in the string. Generally, most of the characters in the string could not start a match. It takes much longer to try matching at a given position in the string than it does to check in a table whether or not the character at that position could start a match. A "fastmap" is such a table. More specifically, a fastmap is an array indexed by the characters in your character set. Under the ASCII encoding, therefore, a fastmap has 256 elements. If you want the searcher to use a fastmap with a given pattern buffer, you must allocate the array and assign the array's address to the pattern buffer's 'fastmap' field. You either can compile the fastmap yourself or have 're_search' do it for you; when 'fastmap' is nonzero, it automatically compiles a fastmap the first time you search using a particular compiled pattern. By setting the buffer's 'fastmap' field before calling 're_compile_pattern', you can reuse a buffer data structure across multiple searches with different patterns, and allocate the fastmap only once. Nonetheless, the fastmap must be recompiled each time the buffer has a new pattern compiled into it. To compile a fastmap yourself, use: int re_compile_fastmap (struct re_pattern_buffer *PATTERN_BUFFER) PATTERN_BUFFER is the address of a pattern buffer. If the character C could start a match for the pattern, 're_compile_fastmap' makes 'PATTERN_BUFFER->fastmap[C]' nonzero. It returns 0 if it can compile a fastmap and -2 if there is an internal error. For example, if '|' is the alternation operator and PATTERN_BUFFER holds the compiled pattern for 'a|b', then 're_compile_fastmap' sets 'fastmap['a']' and 'fastmap['b']' (and no others). 're_search' uses a fastmap as it moves along in the string: it checks the string's characters until it finds one that's in the fastmap. Then it tries matching at that character. If the match fails, it repeats the process. So, by using a fastmap, 're_search' doesn't waste time trying to match at positions in the string that couldn't start a match. If you don't want 're_search' to use a fastmap, store zero in the 'fastmap' field of the pattern buffer before calling 're_search'. Once you've initialized a pattern buffer's 'fastmap' field, you need never do so again--even if you compile a new pattern in it--provided the way the field is set still reflects whether or not you want a fastmap. 're_search' will still either do nothing if 'fastmap' is null or, if it isn't, compile a new fastmap for the new pattern. 14.7.1.7 GNU Translate Tables ............................. If you set the 'translate' field of a pattern buffer to a translate table, then the GNU Regex functions to which you've passed that pattern buffer use it to apply a simple transformation to all the regular expression and string characters at which they look. A "translate table" is an array indexed by the characters in your character set. Under the ASCII encoding, therefore, a translate table has 256 elements. The array's elements are also characters in your character set. When the Regex functions see a character C, they use 'translate[C]' in its place, with one exception: the character after a '\' is not translated. (This ensures that, the operators, e.g., '\B' and '\b', are always distinguishable.) For example, a table that maps all lowercase letters to the corresponding uppercase ones would cause the matcher to ignore differences in case.(1) Such a table would map all characters except lowercase letters to themselves, and lowercase letters to the corresponding uppercase ones. Under the ASCII encoding, here's how you could initialize such a table (we'll call it 'case_fold'): for (i = 0; i < 256; i++) case_fold[i] = i; for (i = 'a'; i <= 'z'; i++) case_fold[i] = i - ('a' - 'A'); You tell Regex to use a translate table on a given pattern buffer by assigning that table's address to the 'translate' field of that buffer. If you don't want Regex to do any translation, put zero into this field. You'll get weird results if you change the table's contents anytime between compiling the pattern buffer, compiling its fastmap, and matching or searching with the pattern buffer. ---------- Footnotes ---------- (1) A table that maps all uppercase letters to the corresponding lowercase ones would work just as well for this purpose. 14.7.1.8 Using Registers ........................ A group in a regular expression can match a (possibly empty) substring of the string that regular expression as a whole matched. The matcher remembers the beginning and end of the substring matched by each group. To find out what they matched, pass a nonzero REGS argument to a GNU matching or searching function (*note GNU Matching:: and *note GNU Searching::), i.e., the address of a structure of this type, as defined in 'regex.h': struct re_registers { unsigned num_regs; regoff_t *start; regoff_t *end; }; Except for (possibly) the NUM_REGS'th element (see below), the Ith element of the 'start' and 'end' arrays records information about the Ith group in the pattern. (They're declared as C pointers, but this is only because not all C compilers accept zero-length arrays; conceptually, it is simplest to think of them as arrays.) The 'start' and 'end' arrays are allocated in one of two ways. The simplest and perhaps most useful is to let the matcher (re)allocate enough space to record information for all the groups in the regular expression. If 're_set_registers' is not called before searching or matching, then the matcher allocates two arrays each of 1 + RE_NSUB elements (RE_NSUB is another field in the pattern buffer; *note GNU Pattern Buffers::). The extra element is set to -1. Then on subsequent calls with the same pattern buffer and REGS arguments, the matcher reallocates more space if necessary. The function: void re_set_registers (struct re_pattern_buffer *BUFFER, struct re_registers *REGS, size_t NUM_REGS, regoff_t *STARTS, regoff_t *ENDS) sets REGS to hold NUM_REGS registers, storing them in STARTS and ENDS. Subsequent matches using BUFFER and REGS will use this memory for recording register information. STARTS and ENDS must be allocated with malloc, and must each be at least NUM_REGS * 'sizeof (regoff_t)' bytes long. If NUM_REGS is zero, then subsequent matches should allocate their own register data. Unless this function is called, the first search or match using BUFFER will allocate its own register data, without freeing the old data. The following examples illustrate the information recorded in the 're_registers' structure. (In all of them, '(' represents the open-group and ')' the close-group operator. The first character in the string STRING is at index 0.) * If the regular expression has an I-th group that matches a substring of STRING, then the function sets 'REGS->start[I]' to the index in STRING where the substring matched by the I-th group begins, and 'REGS->end[I]' to the index just beyond that substring's end. The function sets 'REGS->start[0]' and 'REGS->end[0]' to analogous information about the entire pattern. For example, when you match '((a)(b))' against 'ab', you get: * 0 in 'REGS->start[0]' and 2 in 'REGS->end[0]' * 0 in 'REGS->start[1]' and 2 in 'REGS->end[1]' * 0 in 'REGS->start[2]' and 1 in 'REGS->end[2]' * 1 in 'REGS->start[3]' and 2 in 'REGS->end[3]' * If a group matches more than once (as it might if followed by, e.g., a repetition operator), then the function reports the information about what the group _last_ matched. For example, when you match the pattern '(a)*' against the string 'aa', you get: * 0 in 'REGS->start[0]' and 2 in 'REGS->end[0]' * 1 in 'REGS->start[1]' and 2 in 'REGS->end[1]' * If the I-th group does not participate in a successful match, e.g., it is an alternative not taken or a repetition operator allows zero repetitions of it, then the function sets 'REGS->start[I]' and 'REGS->end[I]' to -1. For example, when you match the pattern '(a)*b' against the string 'b', you get: * 0 in 'REGS->start[0]' and 1 in 'REGS->end[0]' * -1 in 'REGS->start[1]' and -1 in 'REGS->end[1]' * If the I-th group matches a zero-length string, then the function sets 'REGS->start[I]' and 'REGS->end[I]' to the index just beyond that zero-length string. For example, when you match the pattern '(a*)b' against the string 'b', you get: * 0 in 'REGS->start[0]' and 1 in 'REGS->end[0]' * 0 in 'REGS->start[1]' and 0 in 'REGS->end[1]' * If an I-th group contains a J-th group in turn not contained within any other group within group I and the function reports a match of the I-th group, then it records in 'REGS->start[J]' and 'REGS->end[J]' the last match (if it matched) of the J-th group. For example, when you match the pattern '((a*)b)*' against the string 'abb', group 2 last matches the empty string, so you get what it previously matched: * 0 in 'REGS->start[0]' and 3 in 'REGS->end[0]' * 2 in 'REGS->start[1]' and 3 in 'REGS->end[1]' * 2 in 'REGS->start[2]' and 2 in 'REGS->end[2]' When you match the pattern '((a)*b)*' against the string 'abb', group 2 doesn't participate in the last match, so you get: * 0 in 'REGS->start[0]' and 3 in 'REGS->end[0]' * 2 in 'REGS->start[1]' and 3 in 'REGS->end[1]' * 0 in 'REGS->start[2]' and 1 in 'REGS->end[2]' * If an I-th group contains a J-th group in turn not contained within any other group within group I and the function sets 'REGS->start[I]' and 'REGS->end[I]' to -1, then it also sets 'REGS->start[J]' and 'REGS->end[J]' to -1. For example, when you match the pattern '((a)*b)*c' against the string 'c', you get: * 0 in 'REGS->start[0]' and 1 in 'REGS->end[0]' * -1 in 'REGS->start[1]' and -1 in 'REGS->end[1]' * -1 in 'REGS->start[2]' and -1 in 'REGS->end[2]' 14.7.1.9 Freeing GNU Pattern Buffers .................................... To free any allocated fields of a pattern buffer, use the POSIX function 'regfree': void regfree (regex_t *PREG) PREG is the pattern buffer whose allocated fields you want freed; this works because since the type 'regex_t'--the type for POSIX pattern buffers--is equivalent to the type 're_pattern_buffer'. 'regfree' also sets PREG's 'allocated' field to zero. After a buffer has been freed, it must have a regular expression compiled in it before passing it to a matching or searching function. 14.7.2 BSD Regex Functions -------------------------- If you're writing code that has to be Berkeley Unix compatible, you'll need to use these functions whose interfaces are the same as those in Berkeley Unix. 14.7.2.1 BSD Regular Expression Compiling ......................................... With Berkeley Unix, you can only search for a given regular expression; you can't match one. To search for it, you must first compile it. Before you compile it, you must indicate the regular expression syntax you want it compiled according to by setting the variable 're_syntax_options' (declared in 'regex.h' to some syntax (*note Regular Expression Syntax::). To compile a regular expression use: char * re_comp (char *REGEX) REGEX is the address of a null-terminated regular expression. 're_comp' uses an internal pattern buffer, so you can use only the most recently compiled pattern buffer. This means that if you want to use a given regular expression that you've already compiled--but it isn't the latest one you've compiled--you'll have to recompile it. If you call 're_comp' with the null string (_not_ the empty string) as the argument, it doesn't change the contents of the pattern buffer. If 're_comp' successfully compiles the regular expression, it returns zero. If it can't compile the regular expression, it returns an error string. 're_comp''s error messages are identical to those of 're_compile_pattern' (*note GNU Regular Expression Compiling::). 14.7.2.2 BSD Searching ...................... Searching the Berkeley Unix way means searching in a string starting at its first character and trying successive positions within it to find a match. Once you've compiled a pattern using 're_comp' (*note BSD Regular Expression Compiling::), you can ask Regex to search for that pattern in a string using: int re_exec (char *STRING) STRING is the address of the null-terminated string in which you want to search. 're_exec' returns either 1 for success or 0 for failure. It automatically uses a GNU fastmap (*note Searching with Fastmaps::). 14.8 Regular expression syntaxes ================================ Gnulib supports many different types of regular expressions; although the underlying features are the same or identical, the syntax used varies. The descriptions given here for the different types are generated automatically. 14.8.1 'awk' regular expression syntax -------------------------------------- The character '.' matches any single character except the null character. '+' indicates that the regular expression should match one or more occurrences of the previous atom or regexp. '?' indicates that the regular expression should match zero or one occurrence of the previous atom or regexp. '\+' matches a '+' '\?' matches a '?'. Bracket expressions are used to match ranges of characters. Bracket expressions where the range is backward, for example '[z-a]', are invalid. Within square brackets, '\' can be used to quote the following character. Character classes are not supported, so for example you would need to use '[0-9]' instead of '[[:digit:]]'. GNU extensions are not supported and so '\w', '\W', '\<', '\>', '\b', '\B', '\`', and '\'' match 'w', 'W', '<', '>', 'b', 'B', '`', and ''' respectively. Grouping is performed with parentheses '()'. An unmatched ')' matches just itself. A backslash followed by a digit matches that digit. The alternation operator is '|'. The characters '^' and '$' always represent the beginning and end of a string respectively, except within square brackets. Within brackets, '^' can be used to invert the membership of the character class being specified. '*', '+' and '?' are special at any point in a regular expression except: 1. At the beginning of a regular expression 2. After an open-group, signified by '(' 3. After the alternation operator '|' The longest possible match is returned; this applies to the regular expression as a whole and (subject to this constraint) to subexpressions within groups. 14.8.2 'egrep' regular expression syntax ---------------------------------------- The character '.' matches any single character except newline. '+' indicates that the regular expression should match one or more occurrences of the previous atom or regexp. '?' indicates that the regular expression should match zero or one occurrence of the previous atom or regexp. '\+' matches a '+' '\?' matches a '?'. Bracket expressions are used to match ranges of characters. Bracket expressions where the range is backward, for example '[z-a]', are ignored. Within square brackets, '\' is taken literally. Character classes are supported; for example '[[:digit:]]' will match a single decimal digit. Non-matching lists '[^...]' do not ever match newline. GNU extensions are supported: 1. '\w' matches a character within a word 2. '\W' matches a character which is not within a word 3. '\<' matches the beginning of a word 4. '\>' matches the end of a word 5. '\b' matches a word boundary 6. '\B' matches characters which are not a word boundary 7. '\`' matches the beginning of the whole input 8. '\'' matches the end of the whole input Grouping is performed with parentheses '()'. A backslash followed by a digit acts as a back-reference and matches the same thing as the previous grouped expression indicated by that number. For example '\2' matches the second group expression. The order of group expressions is determined by the position of their opening parenthesis '('. The alternation operator is '|'. The characters '^' and '$' always represent the beginning and end of a string respectively, except within square brackets. Within brackets, '^' can be used to invert the membership of the character class being specified. The characters '*', '+' and '?' are special anywhere in a regular expression. The longest possible match is returned; this applies to the regular expression as a whole and (subject to this constraint) to subexpressions within groups. 14.8.3 'ed' regular expression syntax ------------------------------------- The character '.' matches any single character except the null character. '\+' indicates that the regular expression should match one or more occurrences of the previous atom or regexp. '\?' indicates that the regular expression should match zero or one occurrence of the previous atom or regexp. '+ and ?' match themselves. Bracket expressions are used to match ranges of characters. Bracket expressions where the range is backward, for example '[z-a]', are invalid. Within square brackets, '\' is taken literally.

'\B' matches characters which are not a word boundary 7. '\`' matches the beginning of the whole input 8. '\'' matches the end of the whole input Grouping is performed with backslashes followed by parentheses '\(', '\)'. A backslash followed by a digit acts as a back-reference and matches the same thing as the previous grouped expression indicated by that number. For example '\2' matches the second group expression. The order of group expressions is determined by the position of their opening parenthesis '\('. The alternation operator is '\|'. The character '^' only represents the beginning of a string when it appears: 1. At the beginning of a regular expression 2. After an open-group, signified by '\(' 3. After the alternation operator '\|' The character '$' only represents the end of a string when it appears: 1. At the end of a regular expression 2. Before a close-group, signified by '\)' 3. Before the alternation operator '\|' '\*', '\+' and '\?' are special at any point in a regular expression except: 1. At the beginning of a regular expression 2. After an open-group, signified by '\(' 3. After the alternation operator '\|' Intervals are specified by '\{' and '\}'. Invalid intervals such as 'a\{1z' are not accepted.

Any member of the public is a licensee, and is addressed as "you". You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law. A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language. A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them. The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none. The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words. A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not "Transparent" is called "Opaque". Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only. The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text. The "publisher" means any person or entity that distributes copies of the Document to the public. A section "Entitled XYZ" means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as "Acknowledgements", "Dedications", "Endorsements", or "History".) To "Preserve the Title" of such a section when you modify the Document means that it remains a section "Entitled XYZ" according to this definition. The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License. 2. VERBATIM COPYING You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3. You may also lend copies, under the same conditions stated above, and you may publicly display copies. 3. COPYING IN QUANTITY If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects. If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages. If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public. It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document. 4. MODIFICATIONS You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version: A. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission. B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement. C. State on the Title page the name of the publisher of the Modified Version, as the publisher. D. Preserve all the copyright notices of the Document. E. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices. F. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below. G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document's license notice. H. Include an unaltered copy of this License. I. Preserve the section Entitled "History", Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled "History" in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence. J. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the "History" section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission. K. For any section Entitled "Acknowledgements" or "Dedications", Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein. L. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles. M. Delete any section Entitled "Endorsements". Such a section may not be included in the Modified Version. N. Do not retitle any existing section to be Entitled "Endorsements" or to conflict in title with any Invariant Section. O. Preserve any Warranty Disclaimers. If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These titles must be distinct from any other section titles. You may add a section Entitled "Endorsements", provided it contains nothing but endorsements of your Modified Version by various parties--for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard. You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one. The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version. 5. COMBINING DOCUMENTS You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers. The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work. In the combination, you must combine any sections Entitled "History" in the various original documents, forming one section Entitled "History"; likewise combine any sections Entitled "Acknowledgements", and any sections Entitled "Dedications". You must delete all sections Entitled "Endorsements." 6. COLLECTIONS OF DOCUMENTS You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects. You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document. 7. AGGREGATION WITH INDEPENDENT WORKS A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an "aggregate" if the copyright resulting from the compilation is not used to limit the legal rights of the compilation's users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document. If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document's Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate. 8. TRANSLATION Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail. If a section in the Document is Entitled "Acknowledgements", "Dedications", or "History", the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title. 9. TERMINATION You may not copy, modify, sublicense, or distribute the Document except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, or distribute it is void, and will automatically terminate your rights under this License. However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, receipt of a copy of some or all of the same material does not give you any rights to use it. 10. FUTURE REVISIONS OF THIS LICENSE The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See . Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License "or any later version" applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation. If the Document specifies that a proxy can decide which future versions of this License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Document. 11. RELICENSING "Massive Multiauthor Collaboration Site" (or "MMC Site") means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A "Massive Multiauthor Collaboration" (or "MMC") contained in the site means any set of copyrightable works thus published on the MMC site. "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 license published by Creative Commons Corporation, a not-for-profit corporation with a principal place of business in San Francisco, California, as well as future copyleft versions of that license published by that same organization. "Incorporate" means to publish or republish a Document, in whole or in part, as part of another Document. An MMC is "eligible for relicensing" if it is licensed under this License, and if all works that were first published under this License somewhere other than this MMC, and subsequently incorporated in whole or in part into the MMC, (1) had no cover texts or invariant sections, and (2) were thus incorporated prior to November 1, 2008. The operator of an MMC Site may republish an MMC contained in the site under CC-BY-SA on the same site at any time before August 1, 2009, provided the MMC is eligible for relicensing. ADDENDUM: How to use this License for your documents ==================================================== To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page: Copyright (C) YEAR YOUR NAME. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled ``GNU Free Documentation License''. If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the "with...Texts." line with this: with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation. If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.
