The MtHaml integration for the Yii2 framework.
Extension provides a ViewRenders that would allow you to use Haml/Twig view template engines, using Multi target HAML (MtHaml) library.

Requirements

• YII 2.0
• PHP 5.4+
• Composer

Installation with Composer

Installation is recommended to be done via composer by running:

composer require mervick/yii2-mthaml "*"

Also for using twig:

composer require twig/twig "~1.11"

Usage

Add this to your config/main.php file:

return [
    //....
    'components' => [
        'view' => [
            'renderers' => [
                'haml' => [
                    'class' => 'mervick\mthaml\HamlViewRenderer',
                ],
                'twig' => [
                    'class' => 'mervick\mthaml\TwigViewRenderer',
                ],
            ],
        ],
    ],
];

Rendering in Controllers:

class SiteController extends Controller
{
    //....
    public function actionIndex()
    {
        return $this->render('index.haml', $params);
        // or if your want to use twig
        // return $this->render('index.twig', $params);
    }
    //....
}

MtHaml Options

This is default options:

    //....
    'renderers' => [
        'haml' => [
            'class' => 'mervick\mthaml\HamlViewRenderer',
            'cachePath' => '@runtime/Haml/cache',
            'debug' => false,
            'options' => [
                'format' => 'html5',
                // MtHaml escapes everything by default
                'enable_escaper' => true,
                'escape_html' => true,
                'escape_attrs' => true,

            'cachePath' => '@runtime/Twig/cache',
            'debug' => false,
            'options' => [
                // Same as for haml, except "enable_escaper"
                // Twig extension already supports auto escaping, so it turned off for MtHaml
                'enable_escaper' => false,
            ],
        ],
    //....

Filters

Filters take plain text input (with support for #{...} interpolations) and transform it, or wrap it. Learn more

The following filters are available by default:

• css: wraps with style tags
• cdata: wraps with CDATA markup
• escaped: html escapes
• javascript: wraps with script tags
• php: executes the input as php code
• plain: renders as plain text
• preserve: preserves preformatted text

Filters which not enabled by default:

• coffee: compiles coffeescript to javascript
  • dependence coffeescript/coffeescript "~1" (CoffeeScript)
• less: compiles as Lesscss
  • depends one of following:
    oyejorge/less.php "*" (OyejorgeLess)
    or leafo/lessphp "*" (LeafoLess)
• scss: converts scss to css
  • dependence leafo/scssphp "*" (Scss)
    additionally, to use Compass leafo/scssphp-compass "dev-master"
• markdown: converts markdown to html
  • depends one of following:
    michelf/php-markdown "~1.3" (MichelfMarkdown, MichelfMarkdownExtra)
    or cebe/markdown "~1.0.1" (CebeMarkdown, CebeMarkdownExtra, CebeGithubMarkdown)
    or erusev/parsedown "*" (Parsedown)
    or league/commonmark ">=0.5" (CommonMark)
    or kzykhys/ciconia "~1" (CiconiaMarkdown)
    or fluxbb/commonmark "~1@dev" (FluxBBMarkdown)
• rest: converts reStructuredText to html
  • dependence gregwar/rst "~1" (ReST)

To enable non default filters you must first install them via composer.
Example, install coffee filter:

composer require coffeescript/coffeescript "~1"

After what include it in your config file:

    //....
    'renderers' => [
        'haml' => [
            'class' => 'mervick\mthaml\HamlViewRenderer',

            'filters' => [
                // shorten
                'coffee' => 'CoffeeScript',
                // also you can specify filter options
                'coffee' => [

Twig Extensions

The Twig Extensions is a library that provides several useful extensions for Twig.

Install via Composer:

composer require twig/extensions "~1.1.0"

Add the following lines to config file:

    //....
    'renderers' => [
        'twig' => [
            'class' => 'mervick\mthaml\TwigViewRenderer',
            'options' => [
                //...
            ],
            'extensions' => [
                'Text',   # Provides useful filters for text manipulation;
                'I18n',   # Adds internationalization support via the gettext library;
                'Intl',   # Adds a filter for localization of DateTime objects;
                'Array',  # Provides useful filters for array manipulation;
                'Date',   # Adds a filter for rendering the difference between dates.
            ],
        ],
    //....

Attention!

Inside the templates you must use $view instead of $this, example:

-use backend\assets\AppAsset
-use yii\helpers\Html

-AppAsset::register($view)
-$view->beginPage()
!!!
%html{:lang=>Yii::$app->language}
    %head
        %meta{:charset=>Yii::$app->charset}
        %meta(name="viewport" content="width=device-width, initial-scale=1")
        !=Html::csrfMetaTags()
        %title =Html::encode($view->title)
        -$view->head()
    %body
        -$view->beginBody()
        !=$content
        -$view->endBody()
-$view->endPage()
