YAPE::Regex::Explain - explanation of a regular expression
use YAPE::Regex::Explain; my $exp = YAPE::Regex::Explain->new($REx)->explain;
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.
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
[:...:] are now supported.
my $p = YAPE::Regex::Explain->new($regex);
new method (see its docs).
my $p = YAPE::Regex::Explain->explain($mode);
Returns a string explaining the regex. If
regex, it will output a valid regex (instead of the normal string). If
silent, no comments will be added, but the regex will be expanded into a readable format.
