gnus-parameters limitations

["Jochen Küpper" <ml-W2i0oK7yYu0+t3nig+EZI7NAH6kLmebB@public.gmane.org>]

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,
