NAME

6       Template::Namespace::Constants - Compile time constant folding

SYNOPSIS

9           # easy way to define constants
10           use Template;
11
12           my $tt = Template->new({
13               CONSTANTS => {
14                   pi => 3.14,
15                   e  => 2.718,
16               },
17           });
18
19           # nitty-gritty, hands-dirty way
20           use Template::Namespace::Constants;
21
22           my $tt = Template->new({
23               NAMESPACE => {
24                   constants => Template::Namespace::Constants->new({
25                       pi => 3.14,
26                       e  => 2.718,
27                   },
28               },
29           });

DESCRIPTION

32       The Template::Namespace::Constants module implements a namespace han‐
33       dler which is plugged into the Template::Directive compiler module.
34       This then performs compile time constant folding of variables in a par‐
35       ticular namespace.
36

PUBLIC METHODS

38       new(\%constants)
39
40       The new() constructor method creates and returns a reference to a new
41       Template::Namespace::Constants object.  This creates an internal stash
42       to store the constant variable definitions passed as arguments.
43
44           my $handler = Template::Namespace::Constants->new({
45               pi => 3.14,
46               e  => 2.718,
47           });
48
49       ident(\@ident)
50
51       Method called to resolve a variable identifier into a compiled form.
52       In this case, the method fetches the corresponding constant value from
53       its internal stash and returns it.
