Symfony2 Assetic和更少的Sourcemaps [英] Symfony2 Assetic and Less Sourcemaps

问题描述

我不确定如何破解资源少的过滤器以输出源地图文件.我在这里指的是LessFilter https://github. com/kriswallsmith/assetic/blob/master/src/Assetic/Filter/LessFilter.php

I am unsure how I can hack the assetic less filter to output a sourcemap file. I am referring to the LessFilter here https://github.com/kriswallsmith/assetic/blob/master/src/Assetic/Filter/LessFilter.php

第145和146行是创建Symfony\Component\Process\Process对象的地方

  $proc = $pb->getProcess();
  $code = $proc->run();

麻烦的是，此输出被放置到一个文件中.我不确定如何生成第二个源地图文件.

The trouble is this output gets placed into one single file. I am not sure how to generate a second sourcemap file.

我如何扩展此过滤器或破解Assetic核心以使其正常工作?

How can I extend this filter or hack the Assetic core to make this work?

推荐答案

是的，这是正确的位置.但是，您无需对其进行破解.延长它！

Yes, this is the right spot. However, you don't need to hack it. Extend it!

我用这个:

# Using less source maps with Symfony
namespace Acme\MyBundle\Assetic;

use Assetic\Asset\AssetInterface;

class LessFilter extends AsseticLessFilter
{
    public function filterLoad(AssetInterface $asset)
    {
        $sourcemapRoot = realpath(dirname($asset->getSourceRoot() . '/' . $asset->getSourcePath()));

        $this->addTreeOption('sourceMap', true);
        $this->addTreeOption('sourceMapBasepath', $sourcemapRoot);

        parent::filterLoad($asset);
    }
}


// config.yml
assetic:
    filters:
        less:
            class: Acme\MyBundle\Assetic\LessFilter

我在这里发现了这个片段: https://github.com/thomaswelton /blog/blob/master/articles/symfony/using-less-source-maps.md

I found this snipped here: https://github.com/thomaswelton/blog/blob/master/articles/symfony/using-less-source-maps.md

它通过添加两个新的树参数扩展了Filters的filterLoad()方法.所有可用的树参数都可以在这里找到:

It extends the Filters' filterLoad() method by adding two new tree parameters. All available tree parameters can be found here:

您必须爱依赖注入:)
