NAME

re::engine::RE2 - RE2 regex engine

SYNOPSIS

use re::engine::RE2;

if ("Hello, world" =~ /Hello, (world)/) {
    print "Greetings, $1!";
}

DESCRIPTION

Replaces / arguments perl's regex engine in a given lexical scope with RE2.

Rather under development, this is just to show it's possible!

See http://github.com/dgl/re-engine-RE2

METHODS

To access extra functionality of RE2 methods can be called on a compiled regular expression (i.e. a qr//).

• possible_match_range([length = 10])

  Returns an array of two strings: where the expression will start matching and just after where it will finish matching. See RE2's documention on PossibleMatchRange for further details.

  Example:

  my($min, $max) = qr/^(a|b)/->possible_match_range;
  is $min, 'a';
  is $max, 'c';'
