PPIx::Utilities::Node - Extensions to PPI::Node.
This document describes PPIx::Utilities::Node version 1.1.0.
use PPIx::Utilities::Node qw< split_ppi_node_by_namespace >;
my $dom = PPI::Document->new("...");
while ( my ($namespace, $sub_doms) = each split_ppi_node_by_namespace($dom) ) { foreach my $sub_dom ( @{$sub_doms} ) { ... } }
This is a collection of functions for dealing with PPI::Nodes.
Nothing is exported by default.
split_ppi_node_by_namespace($node)
Returns the sub-trees for each namespace in the node as a reference to a hash of references to arrays of PPI::Nodes. Say we've got the following code:
#!perl
my $x = blah();
package Foo;
my $y = blah_blah();
{ say 'Whee!';
package Bar;
something(); }
thingy();
package Baz;
da_da_da();
package Foo;
foreach ( blrfl() ) { ... }
Calling this function on a PPI::Document for the above returns a value that looks like this, using multi-line string literals for the actual code parts instead of PPI trees to make this easier to read:
{ main => [ q< #!perl
my $x = blah(); >, ], Foo => [ q< package Foo;
my $y = blah_blah();
{ say 'Whee!';
}
thingy(); >, q< package Foo;
foreach ( blrfl() ) { ... } >, ], Bar => [ q< package Bar;
something(); >, ], Baz => [ q< package Baz;
da_da_da(); >, ], }
Note that the return value contains copies of the original nodes, and not the original nodes themselves due to the need to handle namespaces that are not file-scoped. (Notice how the first element for ``Foo'' above differs from the original code.)
