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

SYNOPSIS

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".

  COOKIE_REGEX_SET
The name of the cookie used to control regular expression sets.

  MINIMUM_PERL
The minimum version of Perl understood by this parser, as a float. It is currently set to 5.000, since that is the minimum version of Perl accessible to the author.

  MODIFIER_GROUP_MATCH_SEMANTICS
The name of the PPIx::Regexp::Token::Modifier group used to control match semantics.

  MSG_PROHIBITED_BY_STRICT
An appropriate error message for an unknown entity created because 'strict' was in effect. This is rank ad-hocery, and more than usually subject to being changed, without any notice whatsoever. Caveat user.

  NODE_UNKNOWN
The name of the class that represents an unknown node. That is, PPIx::Regexp::Node::Unknown.

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

  STRUCTURE_UNKNOWN
The name of the class that represents an 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.
