SYNOPSIS

Top Close Open
# 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

Top Close Open

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

Top Close Open

new(\%constants)

Top Close Open

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)

Top Close Open

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.
