README

Allows you to use Twig seamlessly in Laravel.

Requirements

TwigBridge >= 0.13 supports Twig 3. If you need Twig 1/2 support, use the 0.12 versions.

Installation

Require this package with Composer

composer require rcrowe/twigbridge

Quick Start

Laravel automatically registers the Service Provider. Use Artisan to publish the twig config file:

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

Create your Twig file in resources/views with the .twig file extension, for example:

<!-- resources/views/welcome.twig -->
<h1>
  Welcome to TwigBridge!
</h1>

At this point, you can now begin using Twig like you would any other view:

// routes/web.php

use Illuminate\Support\Facades\Route;

Route::get('/', static function () {
    return view('welcome');
});

Configuration

Automatic

For Modern Laravel (5.5+): Laravel automatically registers the Service Provider and Facade through Package Auto-Discovery. Manual registration in config/app.php is not required, and you can skip directly to publishing the configuration file below.

Manual

For Legacy Laravel (5.4 and below): If you are using an older version of Laravel without Package Auto-Discovery support, you need to register TwigBridge manually

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);

Publishing Configuration

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/twigbridge.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\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.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/twigbridge.php file to see a list of defined functions/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), 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 they should be self-explanatory.

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 (always available)

Artisan Commands

TwigBridge offers a command for CLI Interaction.

Empty the Twig cache:

$ php artisan twig:clean

Lint all Twig templates:

$ php artisan twig:lint
