libregexp-optimizer-perl - 0.23-1.1 main

This contains two modules, Regexp::List and Regexp::Optimizer.
.
Regexp::List offers a method which turns a list of words into an
optimized regular expression which matches all words therein.
The optimized regular expression is much more efficient than a
simple-minded '|'-concatenation.
.
Regexp:Optimizer factors out common suffices/prefices in regular
expressions (trie optimization). Currently, the user has to optimize
"foo|far" and "foo|goo" into "f(?:oo|ar)" and "[fg]oo" by hand;
this module does it automatically.
