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 Tem
plate::Directive compiler module. This then performs com
pile time constant folding of variables in a particular
namespace.

PUBLIC METHODS

new%(constants)

The new() constructor method creates and returns a refer
ence 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 com
piled form. In this case, the method fetches the corre
sponding constant value from its internal stash and
returns it.
