[Caml-list] ocaml-emacs mode with multiline comments

[Christopher Kauffman]

I have been developing for a few months with ocaml and find it adds a
lot enjoyment to programming. One small irritation that has bothered me
for a while is the handling of comments in the default emacs mode
'ocaml-mode' that comes with the ocaml installation. I may have a
setting wrong in my customization of emacs, but multiline comments never
seem to maintain a consisten color. Usually I will start comment using
the default keystroke M-; (which produces '(* *)') and proceed to type
in the commented area. The first line stays the color of a comment as
determined by the font-lock settings but when I hit enter to go to the
next line and indent, the coloring reverts to the standard non-comment
colors. Using the 'fill-paragraph' command (M-q) usually gets the whole
multiline comment to turn the comment color, but it seems that this
shouldn't be required. Also, there is no smart 'fill-paragraph' for
ocaml-mode so that program code will be filled in with the comments if
there is not a blank line separating them.

I have experimented a bit with Tuareg-mode, the alternate mode for ocaml
editing, and it did solve this, but I prefered the indenting in the
default ocaml-mode and Tuareg seemd to have trouble with font colors for
functions with labels.

There seem to be a number of similar discussions between the two emacs
modes in the archives on this list but I couldn't locate anything that
dealt with these specific issues, the multiline comments and comment
filling, in ocaml-mode. If anyone has pointers to other discussion or
tips, please enlighten me.

Cheers,
Chris

This will solve the indenting "problem":

(add-hook 'tuareg-mode-hook
(function (lambda ()
(setq tuareg-in-indent 0)
(setq tuareg-let-always-indent t)
(setq tuareg-let-indent tuareg-default-indent)
(setq tuareg-with-indent 0)
(setq tuareg-function-indent 0)
(setq tuareg-fun-indent 0)
(setq tuareg-parser-indent 0)
(setq tuareg-match-indent 0)
(setq tuareg-begin-indent tuareg-default-indent)
(setq tuareg-parse-indent tuareg-default-indent); .mll
(setq tuareg-rule-indent tuareg-default-indent)

(setq tuareg-font-lock-symbols nil)
)))
