Re: Has Perl regex DFA engine in its core?

[Athanasius]

From the Camel Book (4^th Edition, page 271):

Alternate Engines

Starting with v5.10, you can even swap out Perl’s entire regex engine and replace it with an alternate pattern-matching library. The underlying mechanics that make this possible are documented in the perlreapi manpage. It’s pretty tough reading, meant for seriously hardcore hackers only.

But you may be in luck. Thanks to CPAN, Perl plug-ins for the alternate regex engine of your choice may already exist. When you use these, you write your patterns normally and, come time to execute them, the alternate engine takes charge.

To find the alternate regex engines available on CPAN, search within the re::engine:: namespace.

Hope that helps,
