Prerequisites

• Mac OS X >= 10.7
• Xcode
• node.js

Getting the code

$ git clone https://github.com/atom/atom-shell.git

Bootstrapping

The bootstrap script will download all necessary build dependencies and create build project files. Notice that we're using ninja to build atom-shell so there is no Xcode project generated.

$ cd atom-shell
$ ./script/bootstrap.py

Building

Build both Release and Debug targets:

$ ./script/build.py

You can also only build the Debug target:

$ ./script/build.py -c Debug

After building is done, you can find Atom.app under out/Debug.

Tests

$ ./script/test.py
