Text::Darts - Perl interface to DARTS by Taku Kudoh

SYNOPSIS

  use Text::Darts; 
  my $td     = Text::Darts->new(qw/ALGOL ANSI ARCO ARPA ARPANET ASCII/);
  my $newstr = $td->gsub("ARPANET is a net by ARPA", sub{ "<<$_[0]>>" });
  # $newstr is now "<<ARPANET>> is a net by <<ARPA>>".
  # or
  my $td     = Text::Darts->open("words.darts");

     qq(<a href="http://dictionary.com/browse/$_[0]">$_[0]</a>)
  }); # link'em all!

DESCRIPTION

Darts, or Double-ARray Trie System is a C++ Template Library by Taku Kudoh. This module makes use of Darts to implement global replace like below;

  $str = s{ (foo|bar|baz) }{ "<<$1>>" }msgex;

The problem with regexp is that it is slow with alterations. Suppose you want to anchor all words that appear in /usr/share/dict/words with regexp. It would be impractical with regexp but Darts make it practical.
