Template::Namespace::Constants(3pm)

Usage

    # 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,
            },
        },
    });

Overview

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.

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.
