Comment Syntax Highlighting in 22.1

Comment Syntax Highlighting in 22.1

[Mike Richards]

I decided to try out 22.1 today and noticed that comments are no
longer highlighted as in the 21.x series (this is at the console, not
xemacs).

For example, consider the following short file called 'test.pl':

#!/bin/perl -w
# this is a comment

In the previous version of emacs, the entire second line would be
highlighted red. But in 22.1 version only the pound sign is red, and
the rest of the line is in the default color (white).

How is it possible to get the entire line to be red again?

It works for me, starting with

   emacs -Q

Customize the face font-lock-comment-face to have a non-default
foreground color.  Since Emacs 22 has font-lock turned on by default,
this face has been changed to have the default foreground color on
8-color displays, and a (supposedly less intrusive) new face
font-lock-comment-delimiter-face was introduced to show the beginning
of the comment.  For more details, see the definitions of these two
faces on font-lock.el.

Thank you Eli and Glenn. This did the trick.

Emacs is Emacs, whether running in the console or under X (or both).
"xemacs" is a different thing.

M-x customize-face font-lock-comment-face

You may wish to set it to inherit from font-lock-comment-delimiter-face.

I know it's longish, but it's worth reading the NEWS (C-h N).

Which major mode are you using?  I ask because I've had no problems
with comment highlighting since upgrading, however I'm only using
cc-mode, CPerl mode, LaTeX mode, etc...

Btw, I've noticed this several times since joining the group: Emacs in
X and XEmacs are two different things, as in they are two different
pieces of software; Emacs is released by the GNU Project, and XEmacs
is released by the folks at www.xemacs.org.
