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.
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.
