VERSION

version 0.01

SYNOPSIS

    use Scalar::Boolean;

    booleanize my $value;  # you can even use `booleanise`
    $value = [];       # $value gets set to 1
    $value = 'Perl';   # $value gets set to 1
    $value = '';       # $value gets set to 0
    $value = '0';      # $value gets set to 0
    $value = undef;    # $value gets set to 0
    $value = ();       # $value gets set to 0

    unbooleanise $value;  # same as `unbooleanize`
    $value = 'foo';  # $value gets set to 'foo'
    …

METHODS

booleanise or booleanize

Accepts scalar variables which will be booleanised. Once booleanised, the variable will convert all values that are assigned to it to their corresponding Boolean values. No effect on already booleanised variables.

unbooleanise or unbooleanize

Accepts scalar variables which will be unbooleanised if already booleanised. No effect on not already booleanised variables.
