Coding style

C++ and Python

For C++ and Python, we just follow Chromium's Coding Style, there is also a script script/cpplint.py to check whether all files confirm.

The python's version we are using now is Python 2.7.

CoffeeScript

For CoffeeScript, we follow GitHub's Style Guide, and also following rules:

• Files should NOT end with new line, because we want to match Google's styles.
• File names should be concatenated with - instead of _, e.g. file-name.coffee rather than file_name.coffee, because in github/atom module names are usually in the module-name form, this rule only applies to .coffee files.

API Names

When creating a new API, we should prefer getters and setters instead of jQuery's one-function style, for example, .getText() and .setText(text) are preferred to .text([text]). There is a discussion of this.
