This is a fork to provide finally twig 2.x, custom functionality and better maintaining. Use at your own risk.

Seamlessly implement Twig in Laravel 5.

Requirements

Laravel	TwigBridge
5.x	>=0.7
4.2 / 4.1	0.6.*
4.0	0.5.*

Installation

Require this package with Composer:

$ composer require rcrowe/twigbridge

Quick Start

Laravel

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::class to the end:

'providers' => [
     // ...

     TwigBridge\ServiceProvider::class,
],

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

'aliases' => [
    // ...

    'Twig' => TwigBridge\Facade\Twig::class,
],

Now that you have both of those lines added to config/app.php we will use Artisan to publish this package's configuration file:

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

You can begin using Twig like you would any other view:

// resources/views/hello.twig
<h1>{{ 'Hello, world' }}<h1>

// app/Http/routes.php
Route::get('/', function () {
    return view('hello');
});

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 and Service Provider in bootstrap/app.php:

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

Configuration

To tell this package to load your Twig files from multiple locations, update the paths array in config/view.php.

Your Twig files can have any of the file extensions configured in config/twigbridge.php under the twig.file_extensions key. By default, .html.twig and .twig are supported.

Usage

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

view('i_am_twig', [...]);

TwigBridge also supports views in other packages:

view('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'}) }}

All output variables are 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 or add new functions to use in your Twig templates. To do this, add a list of extensions for Twig to load to the enabled array in config/twigbridge.php:

'enabled' => [
    '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\DebugExtension
• TwigBridge\Extension\Laravel\Auth
• TwigBridge\Extension\Laravel\Config
• TwigBridge\Extension\Laravel\Dump
• TwigBridge\Extension\Laravel\Form
• TwigBridge\Extension\Laravel\Gate
• 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.* style Facades, enable the Legacy Facades extension:

• TwigBridge\Extension\Laravel\Legacy\Facades

FilterLoader and FunctionLoader

These loader extensions expose Laravel helpers as both Twig functions and filters. Check out the config/twigbridge.php file to see a list of defined functions and filters. You can also add your own.

FacadeLoader

The FacadeLoader extension allows you to call any facade you have configured in config/twigbridge.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), 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 Laravel's standard helper functions.

Functions:

• asset, action, url, route, secure_url, secure_asset
• auth_check, auth_guest, auth_user
• can
• config_get, config_has
• dump
• form_* (All the Form::* methods, snake_cased)
• html_* (All the Html::* methods, snake_cased)
• input_get, input_old, input_has
• link_to, link_to_asset, link_to_route, link_to_action
• session_has, session_get, csrf_token, csrf_field, method_field
• 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

Artisan Commands

TwigBridge also offers two Artisan commands to aid development:

# Empty the Twig cache:
$ php artisan twig:clean

# Lint all Twig templates:
$ php artisan twig:lint
