gnus-parameters limitations

gnus-parameters limitations

[Jochen Küpper]

I am wondering about some limitations of gnus-parameters, using GNU
Emacs 21.3.1 and No Gnus v0.3.


The manual states (correctly) that some settings cannot be performed
through the gnus-parameters variable:
,----[ (info "(gnus)Group Parameters") ]
|    Group parameters can be set via the `gnus-parameters' variable too.
| But some variables, such as `visible', have no effect.  For example:
`----
Why is that?

I am sharing my .emacs and .gnus files between computers (using cvs),
so it would be great to put everything into these files. Having to use
Group Parameters (stored in .newsrc.eld) is fairly uncomfortable. But
also generally it would be nice to have everything stored in one
place.

What would be necessary to improve on that?



Apparently the parsing of gnus-parameters is performed so that the
first matching entry is used. Wouldn't it be nice to allow for
hierarchical settings as with posting styles, where all matching
entries are used and later settings overwrite earlier ones?

Assume the following setting
,----
|      (setq gnus-parameters
|            '(("mail\\..*"
|               (gnus-show-threads nil)
|               (gnus-use-scoring nil)
|               (gcc-self . t)
|               (display . all))
|              ("mail\\.some\\.group"
|               (gnus-use-scoring  t)
|               (to-group . "\\1"))
`----
I would expect to have the following apply to mail.some.group:
,----
|               (gnus-show-threads nil)
|               (gcc-self . t)
|               (display . all))
|               (gnus-use-scoring  t)
|               (to-group . "\\1"))
`----


Greetings,
Jochen

Are you sure that it doesn't work?  When I test it with...

(setq
 gnus-parameters
 '(("gnus"
    (gnus-use-scoring nil)
    (rs-gnus-temp-1 1))
   ("gmane.emacs.gnus.general"
    (gnus-use-scoring t)
    (rs-gnus-temp-1 2)
    (rs-gnus-temp-2 2))))

... and enter gmane.emacs.gnus.general, I get:

  gnus-use-scoring t
  rs-gnus-temp-1 2
  rs-gnus-temp-2 2
  rs-gnus-temp-3 3

Bye, Reiner.

Sorry for the late response, somehow got out of sight. The followup
might be useful for someone looking through the archives.

[...Shows working example...]

Ok, it just works!

My problem was that I put postings-styles into gnus-parameters
,----
| (setq gnus-parameters '(("some/group$"
|                          (posting-style
|                           (eval (jk/ispell-dutch))))
|                         ("some"
|                          (posting-style
|                           (body "Hoi,\n\n\nGroeten,\nJochen")))))
`----
and expected "hierarchical evaluation" of these... I can see the logic
behind this *not* working and reverted to the use of
gnus-posting-styles, so I get what I want.

Jochen
