Version

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

Overview

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'.
