To get started hacking on Zombie.js you'll need Node.js, NPM and CoffeeScript:
$ brew install node npm
$ npm install coffee-script
If you're installing Zombie as an NPM module and want both runtime and
development dependencies, run npm install zombie --dev
.
If you prefer to work from the source directory, you can use cake setup
:
$ git clone git@github.com:assaf/zombie.git
$ cd zombie
$ cake setup
To help isolate your development environment, cake setup
installs all
runtime and development dependencies into the directory node_modules
by running npm bundle
. To see which dependencies are installed, run
npm bundle list installed
(not npm list installed
).
To run the test suite:
$ cake test
If you're hacking on Zombie and testing it in a different project, you
can "install" your working directory using npm link
. Keep in mind,
though, Zombie is written in CoffeeScript ad your project is loading the
compiled JavaScript. You need to keep both synchronized by running
cake build
or cake watch
.
Install the working directory and have all changes compiled in real-time:
$ npm link && cake watch
To generate the documentation:
$ cake doc:pages
$ 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 Vows.
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.
