Twig Composer
=============

[](#twig-composer)

A callback function library for Twig: you will be able to execute code when templates are rendered.

Useful for calling code like controllers, etc. before the template is rendered. This can be done in some frameworks as Symfony or Laravel, but this library works directly with Twig.

For example, if you have a `menu.twig` template which can be included in a layout, you can do:

```
    TwigComposer::getNotifier()->on('menu.twig', [$menuService,generateDinamicMenu]);

```

And then use the menu generated in `menu.twig` template. You won't need to include a call to the service in each controller which uses the layout.

Getting Started
---------------

[](#getting-started)

If you are using composer tool, you can start using TwigComposer requiring the library:

```
require maceda/twig-composer

```

If not, please follow installation instructions.

To be notified of template renders, you need to indicate TwigComposer as the base class for templates when creating Twig\_Environment:

```
$this->twig = new \Twig_Environment(
$loader,
array(
     ...
     'base_template_class' => 'TwigComposer\TwigComposer',
     ...
));

```

To receive callbacks you must register them for each template you want to be notified:

```
TwigComposer::getNotifier()->on('Template_I_Want_To_Watch', $callback);

```

`$callback` will be called each time `'Template_I_Want_To_Watch'` is rendered.

You can also inherit your own base class from TwigComposer if you need to use your own base class for Twig (do not forget to call parent methods when corresponding)

### Installation

[](#installation)

If you do not use composer, you must install and require the following dependencies:

- [christopherobin/EventEmitter](http://daringfireball.net/projects/markdown/)
- [Twig](http://twig.sensiolabs.org/)

You must also include `Relayer.php` and `TwigComposer.php` in your project to use this library.

Running the tests
-----------------

[](#running-the-tests)

This library uses PHPUnit for test. To run the test, execute this command:

```
/usr/bin/php ./vendor/phpunit/phpunit/phpunit ./tests

```

If you want to generate code coverage information, just add the option `--coverage-html DIRECTORY`
