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.
