Group Specific Sorting and Threading

Group Specific Sorting and Threading

[Les Harris]

Apologies if this is easily found.  I can't seem to find how to do it:

Is it possible to have different sorting and threading functions on a
per group basis?

I have a group using the nnrss backend and the feed comes with posts
newest first and threaded. For this group, I would like posts to be
sorted oldest first and have no threading.

Ideally, I would like a way to do this on a Topic level, so these
settings would apply to all groups within a topic.  I may be getting
ahead of myself with that though.

Any help appreciated.

This was almost exactly what I was looking for. It's so simple when
it's staring you in the face.  Thank you much!

The following is what I've put into my Gnus init:

,----
| (add-hook
|  'gnus-summary-mode-hook
|  (lambda ()
|    (when (string-match "^nnrss:CSW.*" gnus-newsgroup-name)
|      (make-local-variable 'gnus-show-threads)
|      (make-local-variable 'gnus-use-adaptive-scoring)
|      (make-local-variable 'gnus-use-scoring)
|      (make-local-variable 'gnus-score-find-score-files-function)
|      (setq gnus-show-threads nil
| 	   gnus-use-adaptive-scoring nil
| 	   gnus-use-scoring t
| 	   gnus-score-find-score-files-function 'gnus-score-find-single)
| 	 (gnus-summary-sort-by-date))))

thanks. I'm also beginning with gnus and this kind of tips are really
helpful.

You can find something close to this in this file
(http://people.irisa.fr/Nicolas.Berthier/file:.gnus.el):

,----
| ;; RSS in summary buffer:
| (add-hook
|  'gnus-summary-mode-hook
|  (lambda ()
|    (when (string-match "^nnrss:.*" gnus-newsgroup-name)
|      (make-local-variable 'gnus-show-threads)
|      (make-local-variable 'gnus-use-adaptive-scoring)
|      (make-local-variable 'gnus-use-scoring)
|      (make-local-variable 'gnus-score-find-score-files-function)
|      (make-local-variable 'gnus-summary-line-format)
|      (setq gnus-show-threads nil
|        gnus-use-adaptive-scoring nil
|        gnus-use-scoring t
|        gnus-score-find-score-files-function 'gnus-score-find-single
|        gnus-summary-line-format "%U%R%z%d %I%(%[ %s %]%)\n"))))

Have a look at group and topic parameters:

http://www.gnus.org/manual/gnus_28.html
http://www.gnus.org/manual/gnus_39.html


You can also have a construct like this in your .gnus.el:

(add-hook 'gnus-summary-mode-hook
   (lambda ()
      (if (equal gnus-newsgroup-name "xxx")
         (progn
            (setq gnus-summary-thread-gathering-function 'gnus-gather-threads-by-subject)
            (setq gnus-use-scoring t)
            (setq gnus-thread-sort-functions ;; and so on...)))))


to override your default values (several tests on the group name can be
used, of course).
