Template::Swig

Perl interface to Django-inspired Swig templating engine.

Synopsis

my $swig = Template::Swig->new;

# Compile and render an inline template:
$swig->compile('message', 'Welcome, {{name}}');
my $output = $swig->render('message', { name => 'Arthur' });

# Compile and render a file:
$swig->compileFromFile('path/to/file.html');
my $output = $swig->render('path/to/file.html', { some_param => 'foo' });

Description

Template::Swig uses JavaScript::V8 and Paul Armstrong's Swig templating engine to provide fast Django-inspired templating in a Perl context. Templates are compiled to JavaScript functions and stored in memory, then executed each time they're rendered.

Swig's feature list includes multiple inheritance, formatter and helper functions, macros, auto-escaping, and custom tags. See the Swig Documentation for more.

Methods

new( template_dir => $path, extends_callback => sub { } )

Initialize a swig instance, given the follwing parameters:

template_dir

Optional path where templates live

extends_callback

Optional callback to be run when Swig encounters an extends tag; receives filename and its encoding as parameters

compile($template_name, $swig_source)

Compile a template given, given a template name and swig template source as a string.

render($template_name, $data)

Render a template, given a name and a reference to a hash of data to interpolate.

Template Examples

Iterate through a list:

{% for image in images %}
    <img src="{{ image.src }}" width="{{ image.width }}" height="{{ image.height }}">
{% else %}
    <div class="message">No images to show</div>
{% endfor %}

Custom helpers / filters:

{{ created|date('r') }}

Inheritance

In main.html:

{% block greeting %}
    Hi, there.
{% endblock %}

In custom.html:

{% extends 'main.html' %}
    
{% block greeting %}
    Welcome, {{ name }}
{% endblock %}
