如何将 LESS 集成到 ZendFramework 2 中

我已经发现本教程 https://stephen.rees-carter.net/thought/integrating-less-with-zend-framework-the-easy-way这是为了Zend框架1。我下载少了放在下面项目/供应商/.

Leafo
└── Less
    ├── Lessc.php
    └── Lessify.php

In 项目/模块/应用程序/Module.php

...
public function onBootstrap(MvcEvent $e)
{
    ...
    $this->compileLess();
}
...
public function compileLess()
{
    if (APPLICATION_ENV == 'production') {
        return;
    }
    require_once PROJECT_PATH . '/vendor/Leafo/Less/Lessc.php';

    $less_file = PROJECT_PATH . '/public/less/style.less';
    $css_file = PROJECT_PATH . '/public/css/style.css';

    $lessc = new \Leafo\Less\Lessc($less_file);
    file_put_contents($css_file, $lessc->parse());
}

不幸的是，我收到以下错误

致命错误：在第 53 行 /Users/jslim/public_html/littlepinktree/module/Application/Module.php 中找不到类“Leafo\Less\Lessc”

我在这里有几个问题：

1. 如何将第 3 方库集成到 ZF2（如果第 3 方库未使用命名空间）？
2. 有没有例子展示如何集成LESS http://lesscss.org/ to ZF2?

我把整个导演都放进去解决了这个问题./module/Application/src/Less

注意：我用回原来的结构如下

src
├── Application
│   └── Controller
│       └── IndexController.php
└── Less
    ├── LICENSE
    ├── Makefile
    ├── README.md
    ├── composer.json
    ├── docs
    │   └── docs.md
    ├── lessc.inc.php
    ├── lessify
    ├── lessify.inc.php
    ├── package.sh
    ├── plessc
    └── tests
        ├── ApiTest.php
        ├── InputTest.php
        ├── README.md
        ├── bootstrap.sh
        ├── inputs
        ├── outputs
        └── sort.php

在应用程序模块中使用类映射./module/Application/Module.php

public function getAutoloaderConfig()
{
    return array(
        'Zend\Loader\ClassMapAutoloader' => array(
            __DIR__ . '/autoload_classmap.php',
        ),
        'Zend\Loader\StandardAutoloader' => array(
            'namespaces' => array(
                __NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
            ),
        ),
    );
}

然后生成autoload_classmap.php

<?php
// Generated by ZF2's ./bin/classmap_generator.php
return array(
    'Application\Module'                     => __DIR__ . '/Module.php',
    'Application\Controller\IndexController' => __DIR__ . '/src/Application/Controller/IndexController.php',
    'lessc'                                  => __DIR__ . '/src/Less/lessc.inc.php',
    'lessc_parser'                           => __DIR__ . '/src/Less/lessc.inc.php',
    'lessc_formatter_classic'                => __DIR__ . '/src/Less/lessc.inc.php',
    'lessc_formatter_compressed'             => __DIR__ . '/src/Less/lessc.inc.php',
    'lessc_formatter_lessjs'                 => __DIR__ . '/src/Less/lessc.inc.php',
    'easyparse'                              => __DIR__ . '/src/Less/lessify.inc.php',
    'tagparse'                               => __DIR__ . '/src/Less/lessify.inc.php',
    'nodecounter'                            => __DIR__ . '/src/Less/lessify.inc.php',
    'lessify'                                => __DIR__ . '/src/Less/lessify.inc.php',
    'ApiTest'                                => __DIR__ . '/src/Less/tests/ApiTest.php',
    'InputTest'                              => __DIR__ . '/src/Less/tests/InputTest.php',
    'lesscNormalized'                        => __DIR__ . '/src/Less/tests/sort.php',
    'SortingFormatter'                       => __DIR__ . '/src/Less/tests/sort.php',
);

终于我可以用了

public function compileLess()
{
    if (APPLICATION_ENV == 'production') {
        return;
    }
    $less_file = PROJECT_PATH . '/public/less/style.less';
    $css_file = PROJECT_PATH . '/public/css/style.css';

    $lessc = new \lessc($less_file);
    file_put_contents($css_file, $lessc->parse());
}
