10 use Template;

12 my $tt = Template->new({
13 CONSTANTS => {
14 pi => 3.14,

19 # nitty-gritty, hands-dirty way
20 use Template::Namespace::Constants;

22 my $tt = Template->new({
23 NAMESPACE => {
24 constants => Template::Namespace::Constants->new({
25 pi => 3.14,

27 },
28 },
29 });

32 The "Template::Namespace::Constants" module implements a namespace
33 handler which is plugged into the "Template::Directive" compiler
34 module. This then performs compile time constant folding of variables
35 in a particular namespace.
36
38 new(\%constants)
39 The new() constructor method creates and returns a reference to a new
40 Template::Namespace::Constants object. This creates an internal stash
41 to store the constant variable definitions passed as arguments.
42
43 my $handler = Template::Namespace::Constants->new({
44 pi => 3.14,
45 e => 2.718,
46 });
47
48 ident(\@ident)
49 Method called to resolve a variable identifier into a compiled form.
50 In this case, the method fetches the corresponding constant value from
51 its internal stash and returns it.
