Throughout this manual you’ve probably noticed lots of variables called
things like gnus-group-line-format and
gnus-summary-mode-line-format. These control how Gnus is to
output lines in the various buffers. There’s quite a lot of them.
Fortunately, they all use the same syntax, so there’s not that much to
be annoyed by.
Here’s an example format spec (from the group buffer): ‘%M%S%5y: %(%g%)\n’. We see that it is indeed extremely ugly, and that there are lots of percentages everywhere.
| • Formatting Basics: | A formatting variable is basically a format string. | |
| • Mode Line Formatting: | Some rules about mode line formatting variables. | |
| • Advanced Formatting: | Modifying output in various ways. | |
| • User-Defined Specs: | Having Gnus call your own functions. | |
| • Formatting Fonts: | Making the formatting look colorful and nice. | |
| • Positioning Point: | Moving point to a position after an operation. | |
| • Tabulation: | Tabulating your output. | |
| • Wide Characters: | Dealing with wide characters. |
Currently Gnus uses the following formatting variables:
gnus-group-line-format, gnus-summary-line-format,
gnus-server-line-format, gnus-topic-line-format,
gnus-group-mode-line-format,
gnus-summary-mode-line-format,
gnus-article-mode-line-format,
gnus-server-mode-line-format, and
gnus-summary-pick-line-format.
All these format variables can also be arbitrary elisp forms. In that
case, they will be evaled to insert the required lines.
Gnus includes a command to help you while creating your own format
specs. M-x gnus-update-format will eval the current form,
update the spec in question and pop you to a buffer where you can
examine the resulting Lisp code to be run to generate the line.
