NAME

6       PPIx::QuoteLike::Dumper - Dump the results of parsing quotelike things
7

SYNOPSIS

9        use PPIx::QuoteLike::Dumper;
10        PPIx::QuoteLike::Dumper->new( '"foo$bar baz"' )
11          ->print();
12

DESCRIPTION

14       This class generates a formatted dump of a PPIx::QuoteLike object, or a
15       string that can be made into such an object.
16

METHODS

18       This class supports the following public methods. Methods not
19       documented here are private, and unsupported in the sense that the
20       author reserves the right to change or remove them without notice.
21
22   new
23        my $dumper = PPIx::QuoteLike::Dumper->new(
24            '"foo$bar baz"',
25            variables  => 1,
26        );
27
28       This static method instantiates the dumper. It takes the string or
29       PPIx::QuoteLike object to be dumped as the first argument. Optional
30       further arguments may be passed as name/value pairs.
31
32       The following optional arguments are recognized:
33
34       encoding name
35           This argument is the encoding of the object to be dumped. It is
36           passed through to PPIx::QuoteLike new() unless the first argument
37           was a PPIx::QuoteLike object, in which case it is ignored.
38
39       indent number
40           This argument specifies the number of additional spaces to indent
41           each level of the parse hierarchy. This is ignored if the "tokens"
42           argument is true.
43
44           The default is 2.
45
46       margin number
47           This argument is the number of additional spaces to indent the
48           parse hierarchy, over those specified by the margin.
49
50           The default is 0.
51
52       perl_version Boolean
53           This argument specifies whether or not the perl versions introduced
54           and removed are included in the dump.
55
56           The default is 0 (i.e. false).
57
58       postderef Boolean
59           THIS ARGUMENT IS DEPRECATED.  See DEPRECATION NOTICE in
60           PPIx::QuoteLike for the details.
61
62           This argument specifies whether or not postfix dereferences are
63           recognized in interpolations. It is passed through to
64           PPIx::QuoteLike new() unless the first argument was a
65           PPIx::QuoteLike object, in which case it is ignored.
66
67       ppi Boolean
68           This argument specifies whether or not a PPI dump is provided for
69           interpolations.
70
71           The default is 0 (i.e. false).
72
73       short Boolean
74           If true, leading 'PPIx::QuoteLike::' will be removed from the class
75           names in the output.
76
77       tokens boolean
78           If true, this argument causes an unstructured dump of tokens found
79           in the parse.
80
81           The default is 0 (i.e. false).
82
83       variables Boolean
84           If true, this argument causes all variables actually interpolated
85           by any interpolations to be dumped.
86
87           The default is 0 (i.e. false).
88
89   dump
90        print PPIx::Regexp::Dumper->dump( 'foo/bar.pl',
91            variables => 1,
92        );
93
94       This static method returns a string that represents a dump of its first
95       argument. It takes the same optional arguments as new(). This method
96       differs from new() in its interpretation of the first argument.
97
98       ·   If the first argument is the name of a file, or is a SCALAR
99           reference, it is made into a PPI::Document and all strings in the
100           document are dumped.
101
102       ·   If the first argument is a PPI::Node all strings in the node are
103           dumped. Note that a PPI::Document is a PPI::Node.
104
105       Otherwise the first argument is handled just like new() would handle
106       it.
107
108       The return is the string representation of the dump.
109
110       In addition to the optional arguments accepted by new(), the following
111       can be specified:
112
113       none
114           This argument specifies a string to return if no dump can be
115           produced (typically because the first argument is neither a file
116           name nor text that is recognized by this package). If unspecified,
117           or specified as "undef", nothing is returned in this case.
118
119       The output for an individual quote-like object differs from the
120       string() output on the same object in that it is preceded by the
121       literal sting being dumped, and file and location information if that
122       can be determined.
123
124   list
125        print map { "$_\n" } $dumper->list();
126
127       This method returns an array containing the dump output. one line per
128       element. The output has no left margin applied, and no trailing
129       newlines. Embedded newlines are probable if the "ppi" argument was
130       specified when the dumper was instantiated.
131
132   print
133        $dumper->print();
134
135       This method simply prints the result of "string" to standard out.
136
137   string
138        print $dumper->string();
139
140       This method adds left margin and newlines to the output of "list",
141       concatenates the result into a single string, and returns that string.
