NAME

6       PPI::Dumper - Dumping of PDOM trees
7

SYNOPSIS

9         # Load a document
10         my $Module = PPI::Document->new( 'MyModule.pm' );
11
12         # Create the dumper
13         my $Dumper = PPI::Dumper->new( $Module );
14
15         # Dump the document
16         $Dumper->print;
17

DESCRIPTION

19       The PDOM trees in PPI are quite complex, and getting a dump of their
20       structure for development and debugging purposes is important.
21
22       This module provides that functionality.
23
24       The process is relatively simple. Create a dumper object with a
25       particular set of options, and then call one of the dump methods to
26       generate the dump content itself.
27

METHODS

29   new $Element, param => value, ...
30       The "new" constructor creates a dumper, and takes as argument a single
31       PPI::Element object of any type to serve as the root of the tree to be
32       dumped, and a number of key->value parameters to control the output
33       format of the Dumper. Details of the parameters are listed below.
34
35       Returns a new "PPI::Dumper" object, or "undef" if the constructor is
36       not passed a correct PPI::Element root object.
37
38       memaddr
39           Should the dumper print the memory addresses of each PDOM element.
40           True/false value, off by default.
41
42       indent
43           Should the structures being dumped be indented. This value is
44           numeric, with the number representing the number of spaces to use
45           when indenting the dumper output. Set to '2' by default.
46
47       class
48           Should the dumper print the full class for each element.
49           True/false value, on by default.
50
51       content
52           Should the dumper show the content of each element. True/false
53           value, on by default.
54
55       whitespace
56           Should the dumper show whitespace tokens. By not showing the
57           copious numbers of whitespace tokens the structure of the code can
58           often be made much clearer. True/false value, on by default.
59
60       comments
61           Should the dumper show comment tokens. In situations where you have
62           a lot of comments, the code can often be made clearer by ignoring
63           comment tokens. True/value value, on by default.
64
65       locations
66           Should the dumper show the location of each token. The values shown
67           are [ line, rowchar, column ]. See "location" in PPI::Element for a
68           description of what these values really are. True/false value, off
69           by default.
70
71   print
72       The "print" method generates the dump and prints it to STDOUT.
73
74       Returns as for the internal print function.
75
76   string
77       The "string" method generates the dump and provides it as a single
78       string.
79
80       Returns a string or undef if there is an error while generating the
81       dump.
82
83   list
84       The "list" method generates the dump and provides it as a raw list,
85       without trailing newlines.
86
87       Returns a list or the null list if there is an error while generation
88       the dump.
