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.

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).

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"))))

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))))
