DESCRIPTION

19       This class generates a formatted dump of a PPIx::Regexp::Element object
20       (or any subclass thereof), a PPIx::Regexp::Tokenizer object, or a
21       string that can be made into one of these.
22

METHODS

24       This class provides the following public methods. Methods not
25       documented here are private, and unsupported in the sense that the
26       author reserves the right to change or remove them without notice.
27
28   new
29        my $dumper = PPIx::Regexp::Dumper->new(
30            '/foo/', ordinal => 1,
31        );
32
33       This static method instantiates the dumper. It takes the string,
34       PPI::Element, PPIx::Regexp::Element, or PPIx::Regexp::Tokenizer to be
35       dumped as the first argument.  Optional further arguments may be passed
36       as name/value pairs.
37
38       The following options are recognized:
39
40       default_modifiers array_reference
41           This argument is a reference to a list of default modifiers to be
42           applied to the statement being parsed. See PPIx::Regexp new() for
43           the details.
44
45       encoding name
46           This argument is the name of the encoding of the regular
47           expression. If specified, it is passed through to
48           PPIx::Regexp->new(). It also causes an "Encode::encode" to be done
49           on any parse content dumped.
50
51       explain Boolean
52           If true, this option causes the "explain()" output of each object
53           to be dumped.
54
55       indent number
56           This argument is the number of additional spaces to indent each
57           level of the parse hierarchy. This is ignored if either the "test"
58           or "tokens" argument is true.
59
60           The default is 2.
61
62       margin number
63           This is the number of spaces to indent the top level of the parse
64           hierarchy. This is ignored if the "test" argument is true.
65
66           The default is zero.
67
68       ordinal Boolean
69           If true, this option causes the "ordinal" values of
70           PPIx::Regexp::Token::Literal objects to be dumped.
71
72       perl_version Boolean
73           If true, this option causes the "perl_version_introduced" and
74           "perl_version_removed" values associated with each object dumped to
75           be displayed.
76
77       postderef Boolean
78           THIS ARGUMENT IS DEPRECATED.  See DEPRECATION NOTICE in
79           PPIx::QuoteLike for the details.
80
81           If true, postfix dereferences are recognized in code and
82           interpolations.  See the tokenizer's new() for details.
83
84       ppi Boolean
85           If true, any Perl code contained in the object will be dumped.
86
87       short Boolean
88           If true, leading 'PPIx::Regexp::' will be removed from the class
89           names in the output.
90
91       strict Boolean
92           This option is passed on to the parser, where it specifies whether
93           the parse should assume "use re 'strict'" is in effect.
94
95           The 'strict' pragma was introduced in Perl 5.22, and its
96           documentation says that it is experimental, and that there is no
97           commitment to backward compatibility. The same applies to the parse
98           produced when this option is asserted.
99
100           The default is false.
101
102       significant Boolean
103           If true, this option causes only significant elements to be dumped.
104
105           The default is false.
106
107       test Boolean
108           If true, this option causes the output to be formatted as a
109           regression test rather than as a straight dump. The output produced
110           by asserting this option is explicitly undocumented, in the sense
111           that the author reserves the right to change the generated output
112           without notice of any kind.
113
114           The default is false.
115
116       tokens Boolean
117           If true, this option causes a dump of tokenizer output rather than
118           of a full parse of the regular expression. This is forced true if
119           the dump is of a PPIx::Regexp::Tokenizer.
120
121           The default is false.
122
123       trace number
124           If greater than zero, this option causes a trace of the parse. This
125           option is unsupported in the sense that the author reserves the
126           right to change it without notice.
127
128           The default is zero.
129
130       verbose number
131           If greater than zero, this option causes additional information to
132           be given about the elements found. This option is unsupported in
133           the sense that the author reserves the right to change it without
134           notice.
135
136           The default is zero.
137
138       If the thing to be dumped was a string, unrecognized arguments are
139       passed to "PPIx::Regexp::Tokenizer->new()". Otherwise they are ignored.
140
141   list
142        print map { "$_\n" } $dumper->list();
143
144       This method produces an array containing the dump output, one line per
145       element. The output has no left margin applied, and no newlines.
146
147   print
148        $dumper->print();
149
150       This method simply prints the result of "string" to standard out.
151
152   string
153        print $dumper->string();
154
155       This method adds left margin and newlines to the output of "list",
156       concatenates the result into a single string, and returns that string.
