Perl Puzzles
Posted by the Perplexing Populous of PerlMonks for the Pondering and Pleasure of Prenctices and Professionals of Perl

I'm going to try to keep a current list of perl-based puzzles that have been posted to Perlmonks here; these include but are not limited to Golf or other types of puzzles. If you find me missing one, drop me a msg or a email and I'll add it.

Golf

Perl Golf are challenges to produce valid perl code that does a given task in as few characters in the code as possible.

Preliminary 'language' for List::Regex

I'd appriciate any comments on this, either to my msg box here or email address and I'll try to post updates here.

I believe I've got the approach to doing this one; I'm going to take Parse::RecDescent, with a fixed grammar, then use that grammar to develop a grammar specifically for the regex itself to pump back into Parse::RecDescent again (meta!). I was going to try to develop my own finite state machine to do this, but I believe I can make use of existing code better than starting from scratch.

Here's the ideas I've had in mind:

All matches would be for the entire array, eg implicit ^ and $ on the regex.

Some examples:

@list = qw( The quick brown fox jumped over the lazy dog ); listparse( ".[9]", @list ); #true listparse( ".[8]", @list ); #false listparse( "The ?adjectives:(.*) fox jumped over the lazy ?what", @lis +t ); # $adjectives would be set as a ref to [ quick, brown ] # $what would be set to "fox" listparse( "The ?speed:{ $speed eq 'quick' } .*", @list ); # $speed would be set to 'quick' listparse( "The ?speed:{ $speed ne 'quick' } .*", @list ); # false listparse( "/word*", @list ); #true listparse( "/word /number .*, @list) ; #false

Hopefully that will give some examples of where I'm going with this...
