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. 15 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. 28 29 The style guides in this project are licensed under the CC-By 3.0 License, 30 which encourages you to share these documents. 31 See [https://creativecommons.org/licenses/by/3.0/][ccl] for more details. 32 33 The following Google style guides live outside of this project: 34 [Go Code Review Comments][go] and [Effective Dart][dart]. 35 36 <a rel="license" href="https://creativecommons.org/licenses/by/3.0/"><img alt="Creative Commons License" style="border-width:0" src="https://i.creativecommons.org/l/by/3.0/88x31.png" /></a> 37 38 [cpp]: https://google.github.io/styleguide/cppguide.html 39 [objc]: objcguide.md 40 [java]: https://google.github.io/styleguide/javaguide.html 41 [py]: https://google.github.io/styleguide/pyguide.html 42 [r]: https://google.github.io/styleguide/Rguide.xml 43 [sh]: https://google.github.io/styleguide/shell.xml 44 [htmlcss]: https://google.github.io/styleguide/htmlcssguide.html 45 [js]: https://google.github.io/styleguide/jsguide.html 46 [angular]: https://google.github.io/styleguide/angularjs-google-style.html 47 [cl]: https://google.github.io/styleguide/lispguide.xml 48 [vim]: https://google.github.io/styleguide/vimscriptguide.xml 49 [cpplint]: https://github.com/google/styleguide/tree/gh-pages/cpplint 50 [emacs]: https://raw.githubusercontent.com/google/styleguide/gh-pages/google-c-style.el 51 [xml]: https://google.github.io/styleguide/xmlstyle.html 52 [go]: https://golang.org/wiki/CodeReviewComments 53 [dart]: https://www.dartlang.org/guides/language/effective-dart 54 [ccl]: https://creativecommons.org/licenses/by/3.0/ 55
