This is a pure Node.js scss/sass linter for Broccoli-based applications and plugins.

npm install --save-dev broccoli-sass-lint

var SassLinter = require('broccoli-sass-lint');

var node = new SassLinter('app/styles'); // Or wherever the files are

Linting configuration can be added in a sass-lint.yml file as expected and documented by Sass Lint. For example:

rules:
  extends-before-mixins: 2 # throws error
  placeholders-in-extend: 1 # log warning
  extends-before-declarations: 0 # no errors or warnings

Here is a sample config file.

Options can be passed as a second argument to SassLinter().

The defaults are shown below;

var SassLinter = require('broccoli-sass-lint');

var node = new SassLinter('app/styles', {
  configPath: '.sass-lint.yml',
  shouldThrowExceptions: true,
  shouldLog: true,
});

A name of the file your config is contained in. This should be a .yml file, preferrably in the root of the Broccoli project.

By default, sass-lint throws exceptions when an error is encountered (note, warnings do not throw errors). Usually this is the preffered functionality.

However, you can stop errors being thrown and, therefore, errors stopping the build process by setting shouldThrowExceptions: false. Use with caution!

Whether to log warnings and errors to the console. When this is set to false you will not be notified or linting errors!

You may override this plugin's default logError() function should you need to intercept file lint objects (e.g. when testing this plugin).

var SassLinter = require('broccoli-sass-lint', {
  logError: function(fileLint) {
    assert.equal(fileLint.errors.length, 0,
      'Should have no errors detected');
  }
});

fileLint is passed in the format returned by sass-lint's lintText() method

When you override logError() this plugin won't log any warnings or errors.

All tests are currently contained in tests/test.js. Tests can be ran with:

npm test

PRs are welcomed and should be issued to the master branch.
