2.1.1 Group Line Specification

The default format of the group buffer is nice and dull, but you can make it as exciting and ugly as you feel like.

Here's a couple of example group lines:

 
     25: news.announce.newusers
 *    0: alt.fan.andrea-dworkin

Quite simple, huh?

You can see that there are 25 unread articles in `news.announce.newusers'. There are no unread articles, but some ticked articles, in `alt.fan.andrea-dworkin' (see that little asterisk at the beginning of the line?).

You can change that format to whatever you want by fiddling with the gnus-group-line-format variable. This variable works along the lines of a format specification, which is pretty much the same as a printf specifications, for those of you who use (feh!) C. See section 8.4 Formatting Variables.

`%M%S%5y: %(%g%)\n' is the value that produced those lines above.

There should always be a colon on the line; the cursor always moves to the colon after performing an operation. Nothing else is required--not even the group name. All displayed text is just window dressing, and is never examined by Gnus. Gnus stores all real information it needs using text properties.

(Note that if you make a really strange, wonderful, spreadsheet-like layout, everybody will believe you are hard at work with the accounting instead of wasting time reading news.)

Here's a list of all available format characters:

`M'
An asterisk if the group only has marked articles.

`S'
Whether the group is subscribed.

`L'
Level of subscribedness.

`N'
Number of unread articles.

`I'
Number of dormant articles.

`T'
Number of ticked articles.

`R'
Number of read articles.

`t'
Estimated total number of articles. (This is really max-number minus min-number plus 1.)

`y'
Number of unread, unticked, non-dormant articles.

`i'
Number of ticked and dormant articles.

`g'
Full group name.

`G'
Group name.

`D'
Newsgroup description.

`o'
`m' if moderated.

`O'
`(m)' if moderated.

`s'
Select method.

`n'
Select from where.

`z'
A string that looks like `<%s:%n>' if a foreign select method is used.

`P'
Indentation based on the level of the topic (see section 2.16 Group Topics).

`c'
Short (collapsed) group name. The gnus-group-uncollapsed-levels variable says how many levels to leave at the end of the group name. The default is 1--this will mean that group names like `gnu.emacs.gnus' will be shortened to `g.e.gnus'.

`m'
`%' (gnus-new-mail-mark) if there has arrived new mail to the group lately.

`p'
`#' (gnus-process-mark) if the group is process marked.

`d'
A string that says when you last read the group (see section 2.17.3 Group Timestamp).

`u'
User defined specifier. The next character in the format string should be a letter. Gnus will call the function gnus-user-format-function-`X', where `X' is the letter following `%u'. The function will be passed a single dummy parameter as argument. The function should return a string, which will be inserted into the buffer just like information from any other specifier.

All the "number-of" specs will be filled with an asterisk (`*') if no info is available--for instance, if it is a non-activated foreign group, or a bogus native group.
