To get started hacking on Zombie.js you'll need Node.js and NPM:
$ brew install node
$ curl http://npmjs.org/install.sh | sudo sh
Next install all the runtime and development dependencies:
$ npm install
To run the test suite:
$ npm test
If you're hacking on Zombie and testing it in a different project, you
can "install" your working directory using npm link
.
To generate the documentation:
$ make doc
$ open html/index.html
Zombie.js is written in CoffeeScript, a language that mixes the best parts of Python and Ruby and compiles one-to-one into JavaScript.
The DOM implementation is JSDOM, which provides an
emulation of DOM Level 3. There are some issues and some features
Zombie.js needs but JSDOM doesn't care for. Those are patched onto
JSDOM in lib/zombie/jsdom_patches.coffee
and
lib/zombie/forms.coffee
.
HTML5 parsing is handled by HTML5.
DOM selectors are provided by JSDOM using Sizzle.js.
Zombie.js is tested using Mocha.
Since we're testing a Web browser, we also need a Web server, so it
spins up an instance of Express. Spinning up
Express and making sure it doesn't power down before all tests are done
(Vows is asynchronous, like everything in Node) is the responsibility of
spec/helper.coffee
.
To stress Zombie.js, we have test cases that use Sammy.js and jQuery.
The scripts themselves are contained in the spec/.scripts
directory.
The dot is necessary to hide these JS files from Vows.
Zombie.js documentation is written in Markdown.
Everything you need to know to get started is covered by README.md
, so
it shows up when you visit the Github
page.
Additional documentation lives in the doc
directory. Annotated source
code generated using Docco.
