1 Google Style Guides
2 ===================
3
4 Every major open-source project has its own style guide: a set of conventions
5 (sometimes arbitrary) about how to write code for that project. It is much
6 easier to understand a large codebase when all the code in it is in a
7 consistent style.
8
9 Style covers a lot of ground, from use camelCase for variable names to
10 never use global variables to never use exceptions. This project
11 ([google/styleguide](https://github.com/google/styleguide)) links to the
12 style guidelines we use for Google code. If you are modifying a project that
13 originated at Google, you may be pointed to this page to see the style guides
14 that apply to that project.

16 This project holds the [C++ Style Guide][cpp], [Objective-C Style Guide][objc],
17 [Java Style Guide][java], [Python Style Guide][py], [R Style Guide][r],
18 [Shell Style Guide][sh], [HTML/CSS Style Guide][htmlcss],
19 [JavaScript Style Guide][js], [AngularJS Style Guide][angular],
20 [Common Lisp Style Guide][cl], and [Vimscript Style Guide][vim]. This project
21 also contains [cpplint][cpplint], a tool to assist with style guide compliance,
22 and [google-c-style.el][emacs], an Emacs settings file for Google style.
23
24 If your project requires that you create a new XML document format, the [XML
25 Document Format Style Guide][xml] may be helpful. In addition to actual style
26 rules, it also contains advice on designing your own vs. adapting an existing
27 format, on XML instance document formatting, and on elements vs. attributes.
