NAME

PPIx::Regexp::Constant - Constants for the PPIx::Regexp system

SYNOPSIS

 use PPIx::Regexp::Constant qw{ $TOKEN_UNKNOWN }
 print "An unknown token's class is $TOKEN_UNKNOWN\n";

INHERITANCE

PPIx::Regexp::Constant is an Exporter.

PPIx::Regexp::Constant has no descendants.

DETAILS

This module defines manifest constants for use by the various PPIx::Regexp modules. These constants are to be considered private to the PPIx::Regexp system, and the author reserves the right to change them without notice.

This module exports the following manifest constants:

$COOKIE_CLASS

The name of the cookie used to control the construction of character classes.

This cookie is set in PPIx::Regexp::Token::Structure when the left square bracket is encountered, and cleared in the same module when a right square bracket is encountered.

$COOKIE_QUANT

The name of the cookie used to control the construction of curly bracketed quantifiers.

This cookie is set in PPIx::Regexp::Token::Structure when a left curly bracket is encountered. It requests itself to be cleared on encountering anything other than a literal comma, a literal digit, or an interpolation, or if more than one comma is encountered. If it survives until PPIx::Regexp::Token::Structure processes the right curly bracket, it is cleared there.

$COOKIE_QUOTE

The name of the cookie used to control the parsing of \Q ... \E quoted literals.

This cookie is set in PPIx::Regexp::Token::Control when a \Q is encountered, and it persists until the next \E.

$MINIMUM_PERL

The minimum version of Perl understood by this parser, as a float. It is currently set to 5.006, since that is the minimum version of Perl accessible to the author.

$RE_CAPTURE_NAME

A regular expression that matches the name of a named capture buffer.

$STRUCTURE_UNKNOWN

The name of the class that represents the unknown structure. That is, PPIx::Regexp::Structure::Unknown.

$TOKEN_LITERAL

The name of the class that represents a literal token. That is, PPIx::Regexp::Token::Literal.

$TOKEN_UNKNOWN

The name of the class that represents the unknown token. That is, PPIx::Regexp::Token::Unknown.
