📄 NAME

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

🚀 Quick Reference

Use Case	Command	Description
Define constants in Template (easy way)	CONSTANTS => { pi => 3.14, e => 2.718 }	Pass a hash of constants to the Template constructor
Define constants using Namespace handler	NAMESPACE => { constants => Template::Namespace::Constants->new({...}) }	Create a namespace handler object for compile-time folding
Use constants in templates	[% constants.pi %]	Access constant values in Template Toolkit templates

🔧 SYNOPSIS

        # 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,
                },
            },
        });

📝 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.

⚙️ METHODS

🛠️ 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.
