I tried to follow the same way `describe-variable' do this,
and adapt it to `describe-face'.
The difficult point is that `find-func' library doesn't handle
symbols but functions and variables. So I defined there a new
variable, `find-face-regexp', and a new function,
`find-face-noselect'.
`find-face-noselect' is a copy of `find-variable-noselect', with:
(let ((library (or file (symbol-file variable 'defvar))))
(find-function-search-for-symbol variable 'variable library)))
replaced by (locally binding `find-variable-regexp'):
(let ((library (or file (symbol-file face 'defface)))
(find-variable-regexp find-face-regexp))
(find-function-search-for-symbol face 'variable library)))
But I think `find-func' library should be fixed to handle arbitrary
kind of symbol (or at least other standard things than functions and
variables).
Follow the patches, generated individualy by "diff -c". It's
important to point out that I didn't test it so much, because I can't
install a more recent CVS version than :
(emacs-version)
==> "GNU Emacs 21.3.50.1 (i386-mingw-windows98.3000)
of 2004-12-23 on FARIBA"
To resume the changes:
- cus-face.el: `custom-declare-face' adds face to
`current-load-list'
- faces.el: `describe-face' adds the string "Defined in ...", with
the ad-hoc button to go to the face definition
- help-mode.el: define the button type `help-face-def'
- emacs-lisp/find-func.el: new variable `find-face-regexp', new
function `find-face-noselect', and a minor docstring fix in
`find-variable-noselect'

Yes, that's what needs to be done.
The rest of the patch looks OK, except that the "loaddefs.el" thingy should
be removed (it's only done for variables, not for functions, and shouldn't
be done for faces either).

Yes. That's why I pointed it out. And why I added
`find-face-noselect' in find-func.el. Initially, I did that trick
enclosing the calls to `find-variable-noselect' (ahem).

Ok. I suppose I let you do it (just remove the `when' form).

Hello
Why `describe-face' does not show a "Defined in `_file_'." button ?
BTW, when I have this code :
(defface my-face
'(...)
"...")
(defvar my-face 'my-face
"...")
If I do `C-h v m y - f a c e <RET>' and try to follow the link
"Defined in ..." in the `*Help*' buffer, the point goes on the
`defface', not on the `defvar'. Is this the normal behaviour ?

Oversight. `defface' doesn't record the definition in load-history.
Patches welcome.

It was a bug. Should be fixed now,
Stefan
