Making group parameters visible to the article buffer too

Making group parameters visible to the article buffer too

[Matt Simmons]

Awhile back[1], there was a discussion about the inaccessibility of
group parameters in Article buffers, specifically for use by washing
functions.  Could they be made accessible in the Article buffer?
Barring that, how can I find out the name of the current group in a
function called by gnus-article-display-hook?

`gnus-newsgroup-name'.

Cool.  It would still be nice if I could get to the group parameters
from the article buffer.  Compare:

  (if (compare gnus-newsgroup-name with a list of newsgroup names)
      (remove egroups stuff))

with

  (if egroups-group   ;; egroups-group set in group parameters
      (remove egroups-stuff))

Yes, but cloning the local variables from the summary buffer into the
article buffer...  I don't know.  Those kinds of things usually have
repercussions.

gnus-summary-buffer is buffer-local to the article buffers, so you can
always do

(save-excursion
  (set-buffer gnus-summary-buffer)
  ;; do that thang)

from the article buffer.

Aren't you doing that already?  For some variables?

Well, I do copy some local variables over into global variables
(whenever you do a command in the summary buffer, basically), but
we're talking 4-5 variables, not a wholesale clone of the local vars.

Well, you've told Matt how he can do his stuff, so I guess when he's
happy...

He's not distraught, which he was before, but he's not happy, because
now he has to implement something parallel to the Group Parameters so
he can figure out which groups to turn on the egroups snarfing for.
He is, perhaps, mildly content.  He's also read something somewhere
saying that one of the indicators of various psychoses is the tendency 
to refer to oneself in the third person, but he doesn't think it means 
anything.

How about an accessor function?  Something like

      (gnus-article-get-group-local-variable 'egroups-group)

I'd code it up & mail it in, but I don't have, and can't get, the
paperwork.

Then he should be happy with 0.35, since it sets the group params in
the article buffer as well.

Lars, the issue is much larger than that though...

1) the group parameters should only set a few? variables in the
   article buffer?  IE, shouldn't the number of new variables in the
   article buffer be an exact match of those in the group params?

2) This would fix a lot of other problems with articles in general
   which are merely "annoying".  For instance, I've always wanted
   gnus-break-pages to be set inside of alt.fan.warlord, but in
   nowhere else.  (I made this request back in the red-gnus time frame, 
   but was shot down, flamed, destroyed, denied, ...  ehh hem...)

Anyway, this is a feature quite a few people have asked about for some 
time...

Plus, wouldn't this help things like signature choosing?  IE,
message-signature-file could be set in the group parameters?  (right
now, I have to set message-signature to my own function which does a
regex match on the group name to determine what I want?  Ick).

In short, group parameters could be *so* much more powerful if allowed 
to affect articles and replies? read/composed underneath it?

Of course; that's the logical solution.  Fix in Pterodactyl Gnus v0.35.

Yay!  *jump with joy*
