DETAILS

18       This module defines manifest constants for use by the various
19       "PPIx::Regexp" modules. These constants are to be considered private to
20       the "PPIx::Regexp" system, and the author reserves the right to change
21       them without notice.
22
23       This module exports the following manifest constants:
24
25   @CARP_NOT
26       This global variable contains the names of all modules in the package.
27
28   ARRAY_REF
29       This is the result of "ref []".
30
31   CODE_REF
32       This is the result of "ref sub {}".
33
34   COOKIE_CLASS
35       The name of the cookie used to control the construction of character
36       classes.
37
38       This cookie is set in PPIx::Regexp::Token::Structure when the left
39       square bracket is encountered, and cleared in the same module when a
40       right square bracket is encountered.
41
42   COOKIE_QUANT
43       The name of the cookie used to control the construction of curly
44       bracketed quantifiers.
45
46       This cookie is set in PPIx::Regexp::Token::Structure when a left curly
47       bracket is encountered. It requests itself to be cleared on
48       encountering anything other than a literal comma, a literal digit, or
49       an interpolation, or if more than one comma is encountered. If it
50       survives until PPIx::Regexp::Token::Structure processes the right curly
51       bracket, it is cleared there.
52
53   COOKIE_QUOTE
54       The name of the cookie used to control the parsing of "\Q ... \E"
55       quoted literals.
56
57       This cookie is set in PPIx::Regexp::Token::Control when a "\Q" is
58       encountered, and it persists until the next "\E".
59
60   COOKIE_REGEX_SET
61       The name of the cookie used to control regular expression sets.
62
63   HASH_REF
64       This is the result of "ref {}".
65
66   LITERAL_LEFT_CURLY_ALLOWED
67       The Perl version at which allowed unescaped literal left curly brackets
68       were removed. This may make more sense if I mention that its value is
69       "undef".
70
71   LITERAL_LEFT_CURLY_REMOVED_PHASE_1
72       The Perl version at which the first phase of unescaped literal left
73       curly bracket removal took place. The value of this constant is
74       '5.025001'.
75
76   LITERAL_LEFT_CURLY_REMOVED_PHASE_2
77       The Perl version at which the second phase of unescaped literal left
78       curly bracket removal took place. The value of this constant is
79       "undef", but it will be assigned a value when the timing of the second
80       phase is known.
81
82   LITERAL_LEFT_CURLY_REMOVED_PHASE_3
83       The Perl version at which the third phase of unescaped literal left
84       curly bracket removal took place. This is the removal of curly brackets
85       after a left parenthesis. The value of this constant is "undef", but it
86       will be assigned a value when the timing of the second phase is known.
87
88   MINIMUM_PERL
89       The minimum version of Perl understood by this parser, as a float. It
90       is currently set to 5.000, since that is the minimum version of Perl
91       accessible to the author.
92
93   MODIFIER_GROUP_MATCH_SEMANTICS
94       The name of the PPIx::Regexp::Token::Modifier group used to control
95       match semantics.
96
97   MSG_PROHIBITED_BY_STRICT
98       An appropriate error message for an unknown entity created because
99       'strict' was in effect. This is rank ad-hocery, and more than usually
100       subject to being changed, without any notice whatsoever. Caveat user.
101
102   NODE_UNKNOWN
103       The name of the class that represents an unknown node. That is,
104       PPIx::Regexp::Node::Unknown.
105
106   RE_CAPTURE_NAME
107       A string representation of a regular expression that matches the name
108       of a named capture buffer.
109
110   REGEXP_REF
111       This is the result of "ref qr{}".
112
113   SCALAR_REF
114       This is the result of "ref \0".
115
116   STRUCTURE_UNKNOWN
117       The name of the class that represents an unknown structure. That is,
118       PPIx::Regexp::Structure::Unknown.
119
120   SUFFICIENT_UTF8_SUPPORT_FOR_WEIRD_DELIMITERS
121       A Boolean which is true if the running version of Perl has UTF-8
122       support sufficient for our purposes.
123
124       Currently that means 5.8.3 or greater, with the specific requirements
125       being "use open qw{ :std :encoding(utf-8) }", "/\p{Mark}/", and the
126       ability to parse things like "qr \N{U+FFFF}foo\N{U+FFFF}".
127
128   TOKEN_LITERAL
129       The name of the class that represents a literal token. That is,
130       PPIx::Regexp::Token::Literal.
131
132   TOKEN_UNKNOWN
133       The name of the class that represents the unknown token. That is,
134       PPIx::Regexp::Token::Unknown.
135
