Using cpplint.py --root with directories at a more outer level will now prepend the header guard with all the directories from the root to the file. For example given ls /a/b/c # /a/b/c/.git /a/b/c/filename.h cpplint.py --root=/a/b /a/b/c/filename.h # C_FILENAME_H_ # no root behavior: cpplint.py /a/b/c/filename.h # FILENAME_H_ Also supports relative paths: cd /a/b/c cpplint.py --root=.. filename.h # C_FILENAME_H_ Note that the old usage is still supported: cd /a/b/c mkdir -p d/e/f touch /a/b/c/d/e/f/filename.h cpplint.py --root=d/e/f d/e/f/filename.h # FILENAME_H_ which would "strip" the prefix rather than prepend an extra prefix. (Invalid root prefixes are as before also ignored)
Google Style Guides
Every major open-source project has its own style guide: a set of conventions (sometimes arbitrary) about how to write code for that project. It is much easier to understand a large codebase when all the code in it is in a consistent style.
“Style” covers a lot of ground, from “use camelCase for variable names” to “never use global variables” to “never use exceptions.” This project (google/styleguide) links to the style guidelines we use for Google code. If you are modifying a project that originated at Google, you may be pointed to this page to see the style guides that apply to that project.
This project holds the C++ Style Guide, Objective-C Style Guide, Java Style Guide, Python Style Guide, R Style Guide, Shell Style Guide, HTML/CSS Style Guide, JavaScript Style Guide, AngularJS Style Guide, Common Lisp Style Guide, and Vimscript Style Guide. This project also contains cpplint, a tool to assist with style guide compliance, and google-c-style.el, an Emacs settings file for Google style.
If your project requires that you create a new XML document format, the XML Document Format Style Guide may be helpful. In addition to actual style rules, it also contains advice on designing your own vs. adapting an existing format, on XML instance document formatting, and on elements vs. attributes.
