16           >;
17
18           my $document = PPI::Document->new(\'Readonly::Scalar my $THINGY => 47.2;');
19
20           # Returns the PPI::Token::Symbol for "$THINGY".
21           my ($constant) = get_constant_name_elements_from_declaring_statement(

DESCRIPTION

26       This is a collection of functions for dealing with PPI::Statements.
27

INTERFACE

29       Nothing is exported by default.
30
31   "get_constant_name_elements_from_declaring_statement($statement)"
32       Given a PPI::Statement, if the statement is a Readonly or Const::Fast
33       declaration statement or a "use constant", returns the names of the
34       things being defined.
35
36       Given
37
38           use constant 1.16 FOO => 'bar';
39
40       this will return the PPI::Token::Word containing 'FOO'.  Given
41
42           use constant 1.16 { FOO => 'bar', 'BAZ' => 'burfle' };
43
44       this will return a list of the PPI::Tokens containing 'FOO' and 'BAZ'.
45       Similarly, given
46
47           Readonly::Hash my %FOO => ( bar => 'baz' );
48
49       or
50
51           const my %FOO => ( bar => 'baz' );
52
53       this will return the PPI::Token::Symbol containing '%FOO'.
