Subject: bug#11601: gnus-tmp-group undocumented
Date: Fri, 01 Jun 2012 13:38:59 -0400

I presume all of the gnus-tmp- stuff should be documented, or this one
should be changed to use some other mechanism.

,----[ (info "(gnus)Group Timestamp") ]
| File: gnus,  Node: Group Timestamp,  Next: File Commands,  Prev: Group Information,  Up: Misc Group Stuff
| 
| 2.18.3 Group Timestamp
| ----------------------
| 
| It can be convenient to let Gnus keep track of when you last read a
| group.  To set the ball rolling, you should add
| `gnus-group-set-timestamp' to `gnus-select-group-hook':
| 
|      (add-hook 'gnus-select-group-hook 'gnus-group-set-timestamp)
| 
|    After doing this, each time you enter a group, it'll be recorded.
| 
|    This information can be displayed in various ways--the easiest is to
| use the `%d' spec in the group line format:
| 
|      (setq gnus-group-line-format
|            "%M\%S\%p\%P\%5y: %(%-40,40g%) %d\n")
| 
|    This will result in lines looking like:
| 
|      *        0: mail.ding                                19961002T012943
|               0: custom                                   19961002T012713
| 
|    As you can see, the date is displayed in compact ISO 8601 format.
| This may be a bit too much, so to just display the date, you could say
| something like:
| 
|      (setq gnus-group-line-format
|            "%M\%S\%p\%P\%5y: %(%-40,40g%) %6,6~(cut 2)d\n")
| 
|    If you would like greater control of the time format, you can use a
| user-defined format spec.  Something like the following should do the
| trick:
| 
|      (setq gnus-group-line-format
|            "%M\%S\%p\%P\%5y: %(%-40,40g%) %ud\n")
|      (defun gnus-user-format-function-d (headers)
|        (let ((time (gnus-group-timestamp gnus-tmp-group)))
|          (if time
|              (format-time-string "%b %d  %H:%M" time)
|            "")))
|
