Adding Compass

This recipe demonstrates how to add Compass to your existing Sass setup.

Steps

1. Install dependencies

Install the Compass Ruby gem and the grunt plugin:

gem install compass
npm install --save-dev grunt-contrib-compass

Note: gem installing is global, so it doesn't matter where you're running the command from, but npm install should be run from inside the project directory.

2. Replace the sass task with compass

Replace:

sass: {
  options: {
    loadPath: 'bower_components'
  },
  dist: {
    files: [{
      expand: true,
      cwd: '<%= config.app %>/styles',
      src: ['*.{scss,sass}'],
      dest: '.tmp/styles',
      ext: '.css'
    }]
  },
  server: {
    files: [{
      expand: true,
      cwd: '<%= config.app %>/styles',
      src: ['*.{scss,sass}'],
      dest: '.tmp/styles',
      ext: '.css'
    }]
  }
},

with:

compass: {
  options: {
    sassDir: '<%= config.app %>/styles',
    cssDir: '.tmp/styles',
    imagesDir: '<%= config.app %>/images',
    javascriptsDir: '<%= config.app %>/scripts',
    fontsDir: '<%= config.app %>/styles/fonts',
    generatedImagesDir: '.tmp/images/generated',
    importPath: 'bower_components',
    httpImagesPath: '../images',
    httpGeneratedImagesPath: '../images/generated',
    httpFontsPath: 'fonts',
    relativeAssets: false,
    assetCacheBuster: false
  },
  dist: {
    options: {
      generatedImagesDir: '<%= config.dist %>/images/generated'
    }
  },
  server: {
    options: {
      debugInfo: true
    }
  }
},

• Now you can use asset functions like font-url() and image-url() in your Sass.
• This solution uses relative paths, but you can edit values of http* options to absolute paths, just make sure not to break grunt-usemin.

3. Update other tasks

watch

-sass: {
+compass: {
   files: ['<%= config.app %>/styles/{,*/}*.{scss,sass}'],
-  tasks: ['sass:server', 'autoprefixer']
+  tasks: ['compass:server', 'autoprefixer']
 },

concurrent

 concurrent: {
   server: [
-    'sass:server',
+    'compass:server',
     'copy:styles'
   ],
   test: [
     'copy:styles'
   ],
   dist: [
-    'sass',
+    'compass',
     'copy:styles',
     'imagemin',
     'svgmin'
   ]
 }

4. Use Compass features

No @import "compass" needed.
