PPIx::Regexp::ConstantUser Contributed Perl DocumentaPPIx::Regexp::Constant(3)

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:

   @CARP_NOT
       This global variable contains the names of all modules in the package.

   ARRAY_REF
       This is the result of "ref []".

   CODE_REF
       This is the result of "ref sub {}".

   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_LOOKAROUND_ASSERTION
       The name	of the cookie used to control the parsing of zero-width
       assertions.

       This cookie is set in PPIx::Regexp::Token::GroupType::Assertion,	and it
       persists	until the end of the assertion.

   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.

   HASH_REF
       This is the result of "ref {}".

   LITERAL_LEFT_CURLY_ALLOWED
       The Perl	version	at which allowed unescaped literal left	curly brackets
       were removed. This may make more	sense if I mention that	its value is
       "undef".

   LITERAL_LEFT_CURLY_REMOVED_PHASE_1
       The Perl	version	at which the first phase of unescaped literal left
       curly bracket removal took place. The value of this constant is
       '5.025001'.

   LITERAL_LEFT_CURLY_REMOVED_PHASE_2
       The Perl	version	at which the second phase of unescaped literal left
       curly bracket removal took place. The value of this constant is
       "undef",	but it will be assigned	a value	when the timing	of the second
       phase is	known.

   LITERAL_LEFT_CURLY_REMOVED_PHASE_3
       The Perl	version	at which the third phase of unescaped literal left
       curly bracket removal took place. This is the removal of	curly brackets
       after a left parenthesis. The value of this constant is "undef",	but it
       will be assigned	a value	when the timing	of the second phase is known.

   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.

   REGEXP_REF
       This is the result of "ref qr{}".

   SCALAR_REF
       This is the result of "ref \0".

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

   SUFFICIENT_UTF8_SUPPORT_FOR_WEIRD_DELIMITERS
       A Boolean which is true if the running version of Perl has UTF-8
       support sufficient for our purposes.

       Currently that means 5.8.3 or greater, with the specific	requirements
       being "use open qw{ :std	:encoding(utf-8) }", "/\p{Mark}/", and the
       ability to parse	things like "qr	\N{U+FFFF}foo\N{U+FFFF}".

   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.

       Support is by the author. Please	file bug reports at
