[% WRAPPER section
title="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.
[%- END %] [% WRAPPER section title="PUBLIC METHODS" -%][% WRAPPER subsection title = "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,
});
[%- END %]
[% WRAPPER subsection
title = "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.
