Over the weekend I tried to find the most elegant solution to
tokenizing and parsing POV-Ray scene files, which uses a c-like

solutions out there, but in trying to understand them it seems
easiest (and take as much time to implement) if I just wrote my
own. (I've never studied lexical analysis, but I understand the
basic concepts).
Does anyone have any opinions on tokenizing and parsing files?
There's more than one way to do it, of course. But a popular Perl
module is Parse::RecDescent. You'll have to install it yourself, as
it's not part of the Perl core distribution. If you have not done
this before, see the perlmodinstall man page.
There's a tutorial for Parse::RecDescent at <http://www.perl.com/pub/
a/2001/06/13/recdecent.html>.
