in thread Breathing life into the (Emacs) cperl-mode

Thanks, but I pass :) For our notorious snippet $a++ / $b; # /; htmlize provides:

$a++ <span class="constant">/</span> <span class="string"> </span> <span class="variable-name">$b</span> <span class="string">; # </span> <span class="constant">/</span>;

That surely is a lot of noise. As you can see (you can, can't you?), this is the output from a broken cperl-mode.

My preferred approach for large-scale fontification tests would be Lindydancer's faceup markup, which together with the other repositories by the same author are really awesome tools to debug and test font-lock features.

Advertisement: As a recent addition, I added Damian Conway's "Perl Best Practice" recommendations for indenting code to M-x cperl-indent-style. I guess that amongst Perlers PBP is waaay more popular than K&R, BSD, or GNU conventions.

    But after your fix, it gives a bit more sense:
    <span class="variable-name">$a</span>++ / <span class="variable-name"> +$b</span>; <span class="comment-delimiter"># </span><span class="comm +ent">/; </span>
    map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
