roadrider has asked for the wisdom of the Perl Monks concerning the following question:

Has anyone else seen this with emacs cperl-mode (v 5.23)?

my $foo; #gets syntax highlighting
$foo = 1;   #not highlighted

[download]

In perl-mode, all references to the variable are highlighted but apparently not so in cperl-mode where only the original reference is.

I have (global-font-lock-mode 1) in my .emacs.

Is this the intended behavior? If not, is there a way to fix it?

    No such problem, but I use cperl-mode 6.2

    Text content at position 37:
 
 
There are text properties here:
  face                 font-lock-variable-name-face
  fontified            t

    And the first thing that Ilya would ask you (also concerning the other problem you posted on gnu.emacs.help) is why you didn't try updating your cperl-mode version.

    In more recent versions of cperl, you can (setq cperl-highlight-variables-indiscriminately t).

      ++ correct answer! :)

      I'm now sitting at a new system and experiencing the same effect with emacs 23.2.1 and cperl 6.2.

      But this line has to be executed at startup in init.el (or .emacsrc or whatever) ...

         Note that that variable is only read at initialization time for
   the variable `cperl-font-lock-keywords-2', so changing it after you
+'ve
   entered CPerl mode the first time will have no effect.

      This setting can also be done per GUI with M-x customize-group RET cperl, so no need to edit init.el manually.

      Cheers Rolf

        You might also want to apply my patch to cperl that highlights variables with explicit package names, too (it is a simplification, but works for correct code).
