Template::Namespace::Constants |

|

# 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,
},
},
}); |
|

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. |
|
||||
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. |
