Hi All,
I'm using emacs to edit journal text files *.jou, for which commented
lines
start with the character "/".
I apply the comment syntax for the "*.jou" files by adding to
the .emacs file
the lines
(add-hook 'find-file-hooks
(lambda ()
(when (string-match "\\.jou$" (buffer-file-name))
(setq comment-start "/")
)
)
)
Now I would also like to turn the text of the commented lines into
red, and for this
I added the line
(font-lock-add-keywords nil '("\\(/.*\\)$" (1 font-lock-comment-
face)))
which unfortunately doesn’t work.
Does anybody know where the mistake is?
Many thanks
gento

I don't have any major-mode for "*.jou" files; if you don't have
either, the following should work for you.
(add-hook 'find-file-hooks
(lambda ()
(when (string-match "\\.jou$" (buffer-file-name))
)
(font-lock-add-keywords nil
'("\\(/.*\\)$"
(1
font-lock-comment-face)))
(font-lock-mode)
)
)
So, in short:
1) Your line with `font-lock-add-keywords' must be evaluated in the
right buffer.
2) And you have to turn `font-lock-mode' on in the buffer for
fontification to happen.
If you want to add more features, you should probably take the time to
define your own major mode "jou-mode":
(info "(emacs)Major modes")
(info "(elisp)Major modes")
PS: I don't know what "jou" files are, but, if you are writing your
own journal file, you should give `org-mode' a try; it's a
wonderful addictive tool to take notes, to make plan and publish
everything in LaTeX, HTML, etc.
And it is included in recent versions of GNU Emacs.

Thank you very much Bruno!
I'm using this
(add-hook 'find-file-hooks
(lambda ()
(when (string-match "\\.jou$" (buffer-file-name))
(setq comment-start "/")
(font-lock-add-keywords nil '("\\(/.*\\)$" (1 font-lock-comment-
face)))
(font-lock-mode)
)
)
)
and it works.
Have a nice day
