How to access absolute path to Gruntfile within Gruntfile?

Question

My Gruntfile.js contains a task for Compass:

grunt.initConfig({

  pkg: grunt.file.readJSON('package.json'),

  // FILE PATHS (custom)
  dir: {
    css:          'resources/styles/css',
    fonts:        'resources/fonts',
    html:         'resources/html',
    images:       'resources/images',
    includes:     'resources/includes',
    node_modules: 'node_modules',
    prototypes:   'resources/html/prototypes',
    resources:    'resources',
    scripts:      'resources/scripts',
    scss:         'resources/styles/scss',
    styles:       'resources/styles',
    styleguide:   'resources/styleguide',
    vendor:       'resources/vendor',
    user: {
       htdocs: '/Volumes/VR\ Mini\ Backup/Backups/Web/Active/myproject/htdocs'
    }
  },

  // COMPASS
  compass: {
    dist: {
      options: {
        ...
        importPath: [
          '<%= dir.user.htdocs %>/<%= dir.resources %>/vendor',
          '<%= dir.user.htdocs %>/<%= dir.resources %>/fonts'
        ]

One of the Compass options is importPath. This expects an absolute/system path. An example importPath is /system/path/to/htdocs/resources/vendor.

As several developers will be working on my project, I'd like to make /system/path/to/htdocs dynamic.

Is there any way to access the path to Gruntfile.js from within this file?

Thanks.

You can leverage Node's path module.

At the top of your gruntfile, add var path = require('path');.

path.resolve() will give you the absolute path.
