NAME

Template::Namespace::Constants - Compile time constant folding

SYNOPSIS

    # easy way to define constants
    use Template;

    my $tt = Template->new({
        CONSTANTS => {
            pi => 3.14,
            e  => 2.718,
        },
    });

    # nitty-gritty, hands-dirty way
    use Template::Namespace::Constants;

    my $tt = Template->new({
        NAMESPACE => {
            constants => Template::Namespace::Constants->new({
                pi => 3.14,
                e  => 2.718,
            },
        },
    });

DESCRIPTION

The Template::Namespace::Constants module implements a namespace handler which is plugged into the Template::Directive compiler module. This then performs compile time constant folding of variables in a particular namespace.

PUBLIC METHODS

`new(\%constants)`

The new() constructor method creates and returns a reference to a new Template::Namespace::Constants object. This creates an internal stash to store the constant variable definitions passed as arguments.

    my $handler = Template::Namespace::Constants->new({
        pi => 3.14,
        e  => 2.718,
    });

`ident(\@ident)`

Method called to resolve a variable identifier into a compiled form. In this case, the method fetches the corresponding constant value from its internal stash and returns it.
