compute to-group parameter automatically?

compute to-group parameter automatically?

[Kai Großjohann]

I have an entry ("^nnimap:foo.bar$" (to-group . "foo.bar")) in
gnus-parameters.  Is there a way to compute the to-group parameter for
many groups, so that I can say ("^nnimap:foo\\." (to-group . XXX)) and
don't have to list each group?

Shame you couldn't do something like:

 ("^nnimap:foo\\.(.*)$" (to-group . $1))

No, but you can say:

(dolist (group gnus-newsrc-alist)
  (when (string-match "^nnml:\\(.*\\)$" (setq group (car group)))
    (insert (format "(\"^%s$\" (to-group . \"%s\"))\n"
		    group (match-string 1 group)))))

:-)                    

Having a more general substring match thing going on in that variable
would be possible, but I don't quite see how to express that:

For example:
   (("mail\\..*"  (gnus-show-threads nil)
		  (gnus-use-scoring nil)
		  (gnus-summary-line-format
			"%U%R%z%I%(%[%d:%ub%-23,23f%]%) %s\n")
		  (gcc-self . t)
		  (display . all))
     ("mail\\.me" (gnus-use-scoring  t))
     ("list\\..*" (total-expire . t)
		  (broken-reply-to . t)))

There's many params that contains strings...  Well, I guess "\\1"
(etc) in them all could be replaced by the matching sub string.  Would
that be useful?

Yes.

Maybe one could also allow Lisp forms to compute the value of a
parameter.  Then the to-group parameter for the help-gnu-emacs mailing
list and friends could automatically be computed by reversing the
order of words...

I've now done so.  (Gah.  I've totally forgotten how to write Emacs
Lisp.  Too me *ages* to figure out how `replace-match' worked.)

Sure.  What would the syntax for that be?

How about the same as for normal group parameters?  The `Group
Parameters' node describes something.

Looking over the code, I think that's probably already possible.
