NAME

PPI::Statement::Variable - Variable declaration statements

SYNOPSIS

# All of the following are variable declarations
my $foo = 1;
my ($foo, $bar) = (1, 2);
our $foo = 1;
local $foo;
local $foo = 1;
LABEL: my $foo = 1;

INHERITANCE

PPI::Statement::Variable
isa PPI::Statement::Expression
    isa PPI::Statement
        isa PPI::Node
            isa PPI::Element

DESCRIPTION

The main intent of the PPI::Statement::Variable class is to describe simple statements that explicitly declare new local or global variables.

Note that this does not make it exclusively the only place where variables are defined, and later on you should expect that the variables method will migrate deeper down the tree to either PPI::Statement or PPI::Node to recognise this fact, but for now it stays here.

METHODS

type

The type method checks and returns the declaration type of the statement, which will be one of either 'my', 'local' or 'our'.

Returns a string of the type, or undef if the type cannot be detected (which is probably a bug).

variables

As for several other PDOM Element types that can declare variables, the variables method returns a list of the canonical forms of the variables defined by the statement.

Returns a list of the canonical string forms of variables, or the null list if it is unable to find any variables.

TO DO

- Write unit tests for this
