PPIx::Utilities::Node(User Contributed Perl DocumentatPPIx::Utilities::Node(3)NAMEPPIx::Utilities::Node - Extensions to PPI::Node.
VERSION
This document describes PPIx::Utilities::Node version 1.1.0.
SYNOPSIS
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} ) {
...
}
}
DESCRIPTION
This is a collection of functions for dealing with PPI::Nodes.
INTERFACE
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.)
