NAME

PPIx::Utilities::Statement - Extensions to PPI::Statement.

VERSION

This document describes PPIx::Utilities::Statement version 1.1.0.

SYNOPSIS

use PPI::Document qw< >;

use PPIx::Utilities::Statement qw<
    get_constant_name_elements_from_declaring_statement
>;

my $document = PPI::Document->new(\'Readonly::Scalar my $THINGY => 47.2;');

# Returns the PPI::Token::Symbol for "$THINGY".
my ($constant) = get_constant_name_elements_from_declaring_statement(
    $document->schild(0)
);

DESCRIPTION

This is a collection of functions for dealing with PPI::Statements.

INTERFACE

Nothing is exported by default.

get_constant_name_elements_from_declaring_statement($statement)

Given a PPI::Statement, if the statement is a Readonly or Const::Fast declaration statement or a use constant, returns the names of the things being defined.

Given

use constant 1.16 FOO => 'bar';

this will return the PPI::Token::Word containing 'FOO'. Given

use constant 1.16 { FOO => 'bar', 'BAZ' => 'burfle' };

this will return a list of the PPI::Tokens containing 'FOO' and 'BAZ'. Similarly, given

Readonly::Hash my %FOO => ( bar => 'baz' );

or

const my %FOO => ( bar => 'baz' );

this will return the PPI::Token::Symbol containing '%FOO'.
