Group Line Specification Problem

Group Line Specification Problem

[Jean-Yves Perrier]

Hello,

I have the following problem:

I want my group buffer to looks like:

[ Gnus -- 0 ]
  [ misc -- 0 ]
*        0: other                    |                    ++++|  (nnml:)
         *: drafts                   |                      ++|  (nndraft:)
  [ Emacs -- 0 ]
    [ Mail/News/AddressBook/Calendar/W3 -- 0 ]
*          0: gnu.emacs.gnus         |          ..............|  (nntp:cachou)
*          0: gnus.dev               |                     +++|  (nnml:)
*          0: bbdb.dev               |                     +++|  (nnml:)
    [ Windoze -- 0 ]
*          0: nt.emacs               |                    ++++|  (nnml:)
  [ OOP -- 0 ]
*        0: oo.gang-of-4-patterns    |                     +++|  (nnml:)

(Don't worry about the . and the +: it is a timestamp histogramm).

I have the following group line definition:
(setq gnus-group-line-format "%M%S%p%P%5y: %(%~(pad-right 25)G%)|%24uz|  %l%z\n")

But this don't take into account the 'folding' of the topic. So I end up with:
[ Gnus -- 0 ]
  [ misc -- 0 ]
*        0: other                    |                    ++++|  (nnml:)
         *: drafts                   |                      ++|  (nndraft:)
  [ Emacs -- 0 ]
    [ Mail/News/AddressBook/Calendar/W3 -- 0 ]
*          0: gnu.emacs.gnus           |          ..............|  (nntp:cachou)
*          0: gnus.dev                 |                     +++|  (nnml:)
*          0: bbdb.dev                 |                     +++|  (nnml:)
    [ Windoze -- 0 ]		       
*          0: nt.emacs                 |                    ++++|  (nnml:)
  [ OOP -- 0 ]
*        0: oo.gang-of-4-patterns    |                     +++|  (nnml:)

				     ^^^
                                     That's the problem.

which I find ugly.

Is there a way, probably in the definition of %(%~(pad-right 25)G%), to take
in account the folding indent?

Best regards,

Ok,

I'm now trying to write a specific function to do this kind of unindent. In order to do
that I need to know the current indent on a group line.

I've tried to play with gnus-topic-group-indentation, gnus-group-group-indentation, but
I didn't succeed.

Any idea(s)?

	I faced the problem of Topic indentation too, and the only thing I
found to take it into account was to use `(current-column)' in my user-defined 
function. Here it is. It's very stupid, but enough for my own use. What would
be nice is to have something like a `flush' post-processing command, to flush
everything after it on the right of the window.


;; This is to flush the output to the right (a constant column).
(defun gnus-user-format-function-g (dummy)
  (let ((length (- (current-fill-column) 15 (current-column))))
    (if (<= length 0)
	" "
      (make-string length ? ))
    ))

It did the trick, thanks!

I've thought about adding a "tab" spec that would say "go to column
x", but I've not written that.  It's non-trivial because of the
(optimized) way text props are added to the lines.
