Regexp::Trie(3)	      User Contributed Perl Documentation      Regexp::Trie(3)

NAME
       Regexp::Trie - builds trie-ized regexp

SYNOPSIS
	 use Regexp::Trie;
	 my $rt	= Regexp::Trie->new;
	 for (qw/foobar	fooxar foozap fooza/){
	   $rt->add($_);
	 }
	 print $rt->regexp, "\n" # (?-xism:foo(?:bar|xar|zap?))

DESCRIPTION
       This module is a	faster but simpler version of Regexp::Assemble or
       Regexp::Optimizer.  It builds a trie-ized regexp	as above.

       This module is faster than Regexp::Assemble but you can only add
       literals.  "a+b"	is treated as "a\+b", not "more	than one a's followed
       by b".

       I wrote this module because I needed something faster than
       Regexp::Assemble	and Regexp::Optimizer.	If you need more minute
       control,	use those instead.

TIPS
       See t/dict2rx.pl	to find	how to convert a big dictionary	into a single
       regexp that can be later	loaded as:

	 my $rx	= do 'dict.rx';

   EXPORT
       None.
