compass loader for webpack

####Warning This is all pretty beta stuff, I don't recommend using this in production just yet. Honestly you're better off using sass-loader and https://github.com/Igosuki/compass-mixins then add node_modules/compass-mixins/lib as an include path.

####You've been warned

Usage

Documentation: Using loaders

var css = require("!raw!compass!./file.scss");
// => returns compiled css code from file.scss, resolves imports
var css = require("!css!compass!./file.scss");
// => returns compiled css code from file.scss, resolves imports and url(...)s

Use in tandem with the style-loader to add the css rules to your document:

require("!style!css!compass!./file.scss");

webpack config

It's recommended to adjust your webpack.config so style!css!compass! is applied automatically on all files ending on .scss:

module.exports = {
  module: {
    loaders: [
      {
        test: /\.scss$/,
        // Query parameters are passed to node-sass
        loader: "style!css!compass?outputStyle=expanded&" +
          "includePaths[]=" +
            (path.resolve(__dirname, "./bower_components")) + "&" +
          "includePaths[]=" +
            (path.resolve(__dirname, "./node_modules"))
      }
    ]
  }
};

If you utilize sprites or anything that utilizes your config.rb images path then you'll need to pass in both imagePath and spriteDist paths.

var imagePath = path.resolve(__dirname, '../images'),
    spriteOutput = imagePath;
require("!style!raw!compass!./file.scss?imagePath=" + imagePath + "&spriteOutput=" + spriteOutput);

Comma separate imports are not supported.

@import "language", "another/module";

should be written as

@import "language";
@import "another/module";

Sorry.

Also this depends on the latest node-sass 2.0 beta to return all included files so we can tell webpack about dependencies. This may or may not work well, and also won't work when node-sass generates errors as it will not complete parsing the CSS and will not return all included files. To get this functionality sass-graph would have to be modified

Then you only need to write: require("./file.scss"). See node-sass for the available options.

Install

npm install compass-loader

Caveats

Currently the sass-loader does not follow all of the webpack loader guidelines. The general problem is that the entry scss-file is passed to node-sass which does pretty much the rest. Thus @import statements inside your scss-files cannot be resolved by webpack's resolver. However, there is an issue for that missing feature in libsass.
