How can I change gnus window configuration for some groups?

How can I change gnus window configuration for some groups?

Hello,

I would like to display one particular group with a smaller summary
buffer. Searching in the documentation, I found that I want to play with
`gnus-buffer-configuration'. I see that in the default setup, it already
has a conditional layout:

#+begin_src emacs-lisp
 (article
  (cond
   (gnus-use-trees
    '(vertical 1.0
	       (summary 0.25 point)
	       (tree 0.25)
	       (article 1.0)))
   (t
    '(vertical 1.0
	       (summary 0.25 point)
	       (article 1.0)))))
#+end_src

Is there a way to adapt this such that I use the layout

#+begin_src emacs-lisp
 (vertical 1.0
           (summary 3 point)
           (article 1.0))
#+end_src

when viewing the "nnvirtual:RSS" group? Should this be a global setting
or a group parameter?

Thanks,

Alan

You can add another condition there, of course. That I
think would be the simplest solution - some purists
will not like it, but they are not the ones who are
doing this, and later using it - you are.

If you can make in into a group parameter specifically
associated to that group, that would be the most
elegant solution. But I don't know how to do that.

Gut feeling, I would do either of:

1. If you want "RET transparency". In the group buffer,
   you select a group by hitting RET. I would rebind
   that to a defun that runs this:

   (string-equal "nnvirtual:RSS" (gnus-group-group-name) )

   If `t', do special treatment. If `nil', do the
   ordinary thing. You might want to use
   current-prefix-arg to replicate ordinary usage of
   the C-u (to quantify articles).

2. If you don't care for "RET transparency": Simply
   assign a key for the RSS group. That key will open
   the group, then change the configuration; or, if
   that flickers, change configuration, open the RSS
   group, then change the configuration back to normal.

Thanks for the suggestion, it's a nice way to do it.

As a less invasive option, I could test for the group name in the window
configuration definition. However it seems that `gnus-group-group-name'
does not work in the summary window (is returns `nil'). Is there
a similar function that returns the name of the current group in
a summary buffer?

Thanks again,

Alan

As I could not find such a function, this is what I ended up
doing. Testing the buffer name is ugly, but it gets the job done.

#+begin_src emacs-lisp
  (defun as/small-summary-p ()
    (equal (buffer-name) "*Summary nnvirtual:RSS*"))

  (gnus-add-configuration
   '(article
     (cond
      ((as/small-summary-p) '(vertical 1.0
                                       (summary 4 point)
                                       (article 1.0)))
      (t '(vertical 1.0
                    (summary 0.25 point)
                    (article 1.0))))))
#+end_src

I think the gnus-newsgroup-name variable holds the value you want. Does
that work?

Yes, thanks a lot!
