Subject: XEmacs & folding, outline, oop...



Hello,

I am looking for some solution to edit Ruby files with XEmacs using
some form of outlining.

I get very basic results by changing the regexps for the simple Outline
minor mode that ships with XEmacs:
   (setq outline-regexp "mo\\|cl\\|..d\\|....d")
The main drawback is that isearch does not work for invisibled code.

The Hideshow minor mode seems more promising. Not the one in the XEmacs
distrib, because it is rather old, but a latter one,  hideshow.el,v 5.31.

However, I get strange results, apparently caused by ruby-move-to-block
from ruby-mode.el not working as forward-sexp does and as Hideshow
expects (if I understood that correctly).

Here is the relevant section in my .xemacs/custom.el:
(require 'hideshow)
(let ((ruby-mode-hs-info
        '(ruby-mode
        "def"                    ; I intend to extend that, when def work
        "end"
        "#"
        ruby-move-to-block
        nil
        )))
(if (not (member ruby-mode-hs-info hs-special-modes-alist))
   (setq hs-special-modes-alist
      (cons ruby-mode-hs-info hs-special-modes-alist))))
(add-hook 'ruby-mode-hook '(lambda () (hs-minor-mode 1)))

The strange result I get is that whatever the def I hide, it hides more
than expected. As an example, using hide-all:
# test
   def a()
     hello
   end
#uncomment me to see a different, better, behaviour
   def b()
     world
   end
   def c()
     "!"
   end


Thanks,

Jean-Hugues
