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.
