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. |
