NAME

YAPE::Regex::Explain - explanation of a regular expression

VERSION

This document refers to YAPE::Regex::Explain version 4.00.

SYNOPSIS

use YAPE::Regex::Explain;
my $exp = YAPE::Regex::Explain->new($REx)->explain;

YAPE MODULES

The YAPE hierarchy of modules is an attempt at a unified means of parsing and extracting content. It attempts to maintain a generic interface, to promote simplicity and reusability. The API is powerful, yet simple. The modules do tokenization (which can be intercepted) and build trees, so that extraction of specific nodes is doable.

DESCRIPTION

This module merely sub-classes YAPE::Regex, and produces a rather verbose explanation of a regex, suitable for demonstration and tutorial purposes. Perl 5.6 regex structures like \p{...} and \P{...} and [:...:] are now supported.

Methods for YAPE::Regex::Explain

• my $p = YAPE::Regex::Explain->new($regex);

  Calls YAPE::Regex's new method (see its docs).

• my $p = YAPE::Regex::Explain->explain($mode);

  Returns a string explaining the regex. If $mode is regex, it will output a valid regex (instead of the normal string). If $mode is silent, no comments will be added, but the regex will be expanded into a readable format.
