README

Allows you to use Twig seamlessly in Laravel 5.

Requirements

TwigBridge >=0.7 requires Laravel 5.

If you need to support for Laravel 4.1/4.2 checkout out TwigBridge 0.6.x, or 0.5.x for Laravel 4.0.

Installation

Require this package with Composer

    composer require epsoftware/twig-bridge

Quick Start

Once Composer has installed or updated your packages you need to register TwigBridge with Laravel itself. Open up config/app.php and find the providers key, towards the end of the file, and add 'TwigBridge\ServiceProvider', to the end:

'providers' => [
     ...
                TwigBridge\ServiceProvider::class,
],

Now find the alliases key, again towards the end of the file, and add 'Twig' => 'TwigBridge\Facade\Twig', to have easier access to the TwigBridge (or Twig_Environment):

'aliases' => [
    ...
                'Twig' => TwigBridge\Facade\Twig::class,
],

Now that you have both of those lines added to config/app.php we will use Artisan to add the new twig config file:

php artisan vendor:publish --provider="TwigBridge\ServiceProvider"

At this point you can now begin using twig like you would any other view

//app/Http/routes.php
//twig template resources/views/hello.twig
Route::get('/', function () {
    return View::make('hello');
});

You can create the twig files in resources/views with the .twig file extension.

resources/views/hello.twig

Configuration

Once Composer has installed or updated your packages you need to register TwigBridge with Laravel itself. Open up config/app.php and find the providers key towards the bottom and add:

'TwigBridge\ServiceProvider',

You can add the TwigBridge Facade, to have easier access to the TwigBridge (or Twig_Environment).

'Twig' => 'TwigBridge\Facade\Twig',

Twig::addExtension('TwigBridge\Extension\Loader\Functions');
Twig::render('mytemplate', $data);

TwigBridge's configuration file can be extended in your ConfigServiceProvider, under the twigbridge key. You can find the default configuration file at vendor/rcrowe/twigbridge/config.

You should use Artisan to copy the default configuration file from the /vendor directory to /config/twigbridge.php with the following command:

php artisan vendor:publish --provider="TwigBridge\ServiceProvider"

If you make changes to the /config/twigbridge.php file you will most likely have to run the twig:clean Artisan command for the changes to take effect.

Installation on Lumen

For Lumen, you need to load the same Service Provider, but you have to disable the Auth, Translator and Url extensions in your local configuration. Copy the config/twigbridge.php file to your local config folder and register the configuration + Service Provider in bootstrap/app.php:

$app->configure('twigbridge');
$app->register('TwigBridge\ServiceProvider');

Usage

You call the Twig template like you would any other view:

// Without the file extension
View::make('i_am_twig', [...])

TwigBridge also supports views in other packages:

View::make('pagination::simple')

The above rules continue when extending another Twig template:

{% extends "parent" %}
{% extends "pagination::parent" %}

You can call functions with parameters:

{{ link_to_route('tasks.edit', 'Edit', task.id, {'class': 'btn btn-primary'}) }}

And output variables, escaped by default. Use the raw filter to skip escaping.

{{ some_var }}
{{ html_var | raw }}
{{ long_var | str_limit(50) }}

Extensions

Sometimes you want to extend / add new functions for use in Twig templates. Add to the enabled array in config/extensions.php a list of extensions for Twig to load.

'enabled' => array(
    'TwigBridge\Extensions\Example'
)

TwigBridge supports both a string or a closure as a callback, so for example you might implement the Assetic Twig extension as follows:

'enabled' => [
    function($app) {
        $factory = new Assetic\Factory\AssetFactory($app['path'].'/../some/path/');
        $factory->setDebug(false);
        // etc.....
        return new Assetic\Extension\Twig\AsseticExtension($factory);
    }
]

TwigBridge comes with the following extensions enabled by default:

Twig_Extension_Debug
TwigBridge\Extension\Laravel\Auth
TwigBridge\Extension\Laravel\Config
TwigBridge\Extension\Laravel\Dump
TwigBridge\Extension\Laravel\Form
TwigBridge\Extension\Laravel\Html
TwigBridge\Extension\Laravel\Input
TwigBridge\Extension\Laravel\Session
TwigBridge\Extension\Laravel\String
TwigBridge\Extension\Laravel\Translator
TwigBridge\Extension\Laravel\Url
TwigBridge\Extension\Loader\Facades
TwigBridge\Extension\Loader\Filters
TwigBridge\Extension\Loader\Functions

To enable '0.5.x' style Facades, enable the Legacy Facades extension:

TwigBridge\Extension\Laravel\Legacy\Facades

FilterLoader and FunctionLoader

These loader extensions exposes Laravel helpers as both Twig functions and filters.

Check out the config/extensions.php file to see a list of defined function / filters. You can also add your own.

FacadeLoader

The FacadeLoader extension allows you to call any facade you have configured in config/extensions.php. This gives your Twig templates integration with any Laravel class as well as any other classes you alias.

To use the Laravel integration (or indeed any aliased class and method), just add your facades to the config and call them like URL.to(link) (instead of URL::to($link))

Functions/Filters/Variables

The following helpers/filters are added by the default Extensions. They are based on the helpers and/or facades, so should be self explaining.

Functions:

asset, action, url, route, secure_url, secure_asset
auth_check, auth_guest, auth_user
config_get, config_has
dump
form_* (All the Form::* methods, snake_cased)
html_* (All the Html::* methods, snake_cased)
input_get, input_old
link_to, link_to_asset, link_to_route, link_to_action
session_has, session_get, csrf_token
str_* (All the Str::* methods, snake_cased)
trans, trans_choice
url_* (All the URL::* methods, snake_cased)

Filters:

camel_case, snake_case, studly_case
str_* (All the Str::* methods, snake_cased)
trans, trans_choice

Global variables:

app: the Illuminate\Foundation\Application object
errors: The $errors MessageBag from the Validator (always available)
