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.
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.
