Using with Streamline

CoffeeCoverage supports streamline'd coffee files. The easiest way to enable streamline support is by writing a custom loader. First, install streamline:

npm install --save streamline

Write the following to a file called 'registerCoffeeCoverage.js' in your project's root folder:

path = require('path');

require('coffee-coverage').register({
    basePath: process.cwd(),
    exclude: ['/test', '/node_modules', '/.git'],
    instrumentor: 'istanbul',
    coverageVar: '_$coffeeIstanbul',
    writeOnExit: 'coverage/coverage-coffee.json',
    streamlinejs: true,
    cachePath: path.join process.cwd(), 'build/coffee-coverage-cache'
    initAll: true
});

Then, run your tests:

mocha --require ./registerCoffeeCoverage --reporter html-cov ...

You can also set streamlinejs to a set of options to pass to streamline. Any option you can pass to transform is supported.

It is highly recommended to pass the cachePath option when using streamline, as the streamline compiler can be a bit slow.
