Hello,
I have had a hard time using ruby-mode.el, but that was my first
exposure to XEmacs, so…
1- xemacs: I’ve tried to install ruby-mode.el, and I have searched
Internet to find a solution, but I’m unable to make it work… and it’s
a little bit of a pain not having it! 
If your problem is that font-lock isn’t working, then you need to add
(load “font-lock”)
at the start of your .emacs.
Thank you fo rthe answer.
I tried and it does not seem to work.
Actually, my problem is that I’m not able to use neither the indentation
neither the color of the source code (Yes, I have set the
“Options->Syntax Highlighting->In this buffer” option).
I tried to put the ruby-mode.el in the path of xemacs, and I have added
(require 'ruby-mode) both in my .emacs and .xemacs-custom but it seems
not to work. Have I missed a point in the ruby-mode.el installation? I
searched the web for a general way of installing the *.el files, but I
did not find any result…
Thanks!
Guille
I put some *.el file in my .xemacs directory, and then I set the
load path:
(setq load-path (cons (expand-file-name “~/.xemacs/”) load-path))
; This one may or may not be necessary (it is not for me)
;(load “font-lock”)
Then I autoload the ruby mode:
(autoload 'ruby-mode “ruby-mode”
“Mode for editing ruby source files”)
(setq auto-mode-alist
(append '((“\.rb$” . ruby-mode)) auto-mode-alist))
(setq interpreter-mode-alist (append '((“ruby” . ruby-mode))
interpreter-mode-alist))
Then I added this… but I am not sure about what it does, maybe
it set the font mode automatically when in ruby mode:
(add-hook 'ruby-mode-hook 'font-lock-fontify-buffer)
And also this… so that I can manually force a syntax highlighting:
;Brian Marick, marick@testing.com
(global-set-key “^z” 'font-lock-fontify-buffer)
Overall, I end up trying to disable the automatic fontifying and
activate it manually only, when I need it. I did that because it
is slow on large file (1000 lines or so).
Unfortunately I still have some intrusive “rescanning…” occurring
from time to time. For large files, this is inconvenient because the
UI is freezed during that rescanning.
Hope this helps. If you manage to setup a better solution, please
tell about it.
Yours,
Jean-Hugues
P.S. Here is my full .xemacs/custom.el, some stuff work, some
don’t.
