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".

   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.

   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 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.
