在 Symfony 2 中使用 Mustache 作为模板语言 [英] Using Moustache as a templating language in Symfony 2

问题描述

我开始使用 symfony 2，但我想使用 mustache 作为模板语言而不是 Twig 或 PHP.我不想使用 mustache，因为它完全没有逻辑，而且如果我决定处理模板客户端的渲染，我也可以在 javascript 中使用它.

I'm starting to use symfony 2 but I'd like to use moustache as the templating language instead of Twig or PHP. I wan't to use moustache because it's totally logicless and because I can also use it in javascript if I decide to handle the rendering of the template clientside.

怎么做?

如果您还不熟悉 Symfony 模板系统和包配置，请在开始编码之前查看以下内容:

If you are not yet familiar with Symfony templating systems and bundle configuration take a look at these before you start coding:

• 如何公开 Bundle 的语义配置
• 创建和使用模板
• 如何使用 PHP 而不是 Twig 作为模板

现在是一个快速入门的食谱.以下面的例子为例，不必拘泥于所选择的名称.

And now a quick recipe to get you started. Take the following as loose examples, no need to stick with the names choosed.

1.创建一个 Resources/config/mustache.xml 来定义您的服务并标识您的模板引擎服务(将其标记为 "templating.engine").

1. Create a Resources/config/mustache.xml to define your services and to identify your template engine service (tag it as "templating.engine").

您可以使用 Yaml 和 PHP 而不是 XML，但后者更适合公共"包.

<service id="mustache" class="Mustache">
    <file>Mustache.php</file>
</service>

<service id="templating.engine.mustache" class="MustacheBundleMustacheEngine" public="false">
        <argument type="service" id="mustache" />
        <argument type="service" id="templating.name_parser"/>
        <argument type="service" id="templating.loader" />
        <tag name="templating.engine" />
</service>

示例:

• Twig
• PHP
• Smarty

2.创建一个 Extension 类来处理您的包的语义配置.

2. Create an Extension class to handle the semantic configuration for your bundle.

<?php

namespace MustacheBundle;

use SymfonyComponentHttpKernelDependencyInjectionExtension;
use SymfonyComponentDependencyInjectionLoaderXmlFileLoader;

class MustacheExtension extends Extension
{
    $loader = new XmlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
    $loader->load('mustache.xml');

    // you may parse the $configs array here
    // see: http://symfony.com/doc/current/cookbook/bundles/extension.html#parsing-the-configs-array
}

上一个类的存在意味着您现在可以在任何配置文件中定义一个 mustache 配置命名空间.

The presence of the previous class means that you can now define a mustache configuration namespace in any configuration file.

示例:

• Twig
• Smarty

3.[可选]创建一个Configuration类来验证和合并配置

3. [Optional] Create a Configuration class to validate and merge configuration

<?php

namespace MustacheDependencyInjection;

use SymfonyComponentConfigDefinitionBuilderTreeBuilder;
use SymfonyComponentConfigDefinitionConfigurationInterface;

class Configuration implements ConfigurationInterface
{
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder();
        $rootNode = $treeBuilder->root('mustache');

        // see: http://symfony.com/doc/current/cookbook/bundles/extension.html#validation-and-merging-with-a-configuration-class
    }
}

示例:

• Twig
• Smarty

4.创建一个 MustacheEngine 来实现 引擎接口

4. Create a MustacheEngine that implements EngineInterface

<?php

namespace MustacheBundle;

use SymfonyBundleFrameworkBundleTemplatingEngineInterface;
use SymfonyComponentTemplatingTemplateNameParserInterface;
use SymfonyComponentTemplatingLoaderLoaderInterface;

use SymfonyComponentHttpFoundationResponse;

class MustacheBundle implements EngineInterface
{
    public function __construct(Mustache $mustache, TemplateNameParserInterface $parser, LoaderInterface $loader)
    {
        $this->mustache = $mustache;
        $this->parser = $parser;
    }

    public function render($name, array $parameters = array())
    {
        $template = $this->load($name);

        return $this->mustache->render($template);
    }

    // Renders a view and returns a Response.
    public function renderResponse($view, array $parameters = array(), Response $response = null)
    {
        if (null === $response) {
            $response = new Response();
        }

        $response->setContent($this->render($view, $parameters));

        return $response;
    }

    // Returns true if the template exists.
    public function exists($name)
    {
        try {
            $this->load($name);
        } catch (InvalidArgumentException $e) {
            return false;
        }

        return true;
    }

    // Returns true if this class is able to render the given template.
    public function supports($name)
    {
        $template = $this->parser->parse($name);

        return 'mustache' === $template->get('engine');
    }

    // Loads the given template.
    // Should return the template name or a Mustache template object
    protected function load($name)
    {
        $template = $this->parser->parse($name);
        $template = $this->loader->load($template);

        return (string) $template;
    }

示例:

• Twig
• PHP
• Smarty

5.在应用程序配置文件中启用您闪亮的新模板引擎:

# app/config/config.yml
templating:    { engines: ['twig', 'mustache'] }

6.试试

<?php
// src/Acme/HelloBundle/Controller/HelloController.php

public function indexAction($name)
{
    return $this->render('AcmeHelloBundle:Hello:index.html.mustache', array('name' => $name));
}
