6 PPIx::Utilities::Node - Extensions to PPI::Node.
7
9 This document describes PPIx::Utilities::Node version 1.1.0.
10
12 use PPIx::Utilities::Node qw< split_ppi_node_by_namespace >;
13
14 my $dom = PPI::Document->new("...");
15
16 while (
17 my ($namespace, $sub_doms) = each split_ppi_node_by_namespace($dom)
18 ) {
19 foreach my $sub_dom ( @{$sub_doms} ) {
20 ...
21 }
22 }
23
25 This is a collection of functions for dealing with PPI::Nodes.
26
28 Nothing is exported by default.
29
30 split_ppi_node_by_namespace($node)
31 Returns the sub-trees for each namespace in the node as a reference to
32 a hash of references to arrays of PPI::Nodes. Say we've got the
33 following code:
34
35 #!perl
36
37 my $x = blah();
38
39 package Foo;
40
41 my $y = blah_blah();
42
43 {
44 say 'Whee!';
45
46 package Bar;
47
48 something();
49 }
50
51 thingy();
52
53 package Baz;
54
55 da_da_da();
56
57 package Foo;
58
59 foreach ( blrfl() ) {
60 ...
61 }
62
63 Calling this function on a PPI::Document for the above returns a value
64 that looks like this, using multi-line string literals for the actual
65 code parts instead of PPI trees to make this easier to read:
66
67 {
68 main => [
69 q<
70 #!perl
71
72 my $x = blah();
73 >,
74 ],
75 Foo => [
76 q<
77 package Foo;
78
79 my $y = blah_blah();
80
81 {
82 say 'Whee!';
83
84 }
85
86 thingy();
87 >,
88 q<
89 package Foo;
90
91 foreach ( blrfl() ) {
92 ...
93 }
94 >,
95 ],
96 Bar => [
97 q<
98 package Bar;
99
100 something();
101 >,
102 ],
103 Baz => [
104 q<
105 package Baz;
106
107 da_da_da();
108 >,
109 ],
110 }
111
112 Note that the return value contains copies of the original nodes, and
113 not the original nodes themselves due to the need to handle namespaces
114 that are not file-scoped. (Notice how the first element for "Foo"
115 above differs from the original code.)
