NAME
Text::Tx - Perl interface to Tx by OKANOHARA Daisuke
SYNOPSIS
use Text::Tx;
my $td = Text::Tx->open("words.tx");
my $newstr = $td->gsub($str, sub{
qq(<a href="
http://dictionary.com/browse/$_[0]">$_[0]</a>)
}); # link'em all!
DESCRIPTION
Tx is a library for a compact trie data structure by OKANOHARA Daisuke.
Tx requires 1/4 - 1/10 of the memory usage compared to the previous
implementations, and can therefore handle quite a large number of keys
(e.g. 1 billion) efficiently.
Suppose words.tx is a pre-built tx by txbuild command which contains
foo, bar, and baz,
$newstr = $td->gsub($str, sub{"<$_[0]>"});
is equivalent to
my $newstr = $str;
$newstr = s{ (foo|bar|baz) }{ "<<$1>" }msgex;
Sounds less convenient? But what happens if the alteration contains
thousands of words? It takes a whole lot of time and memory just to
compile the regexp. Tx and Text::Tx does just that.
