Format All The Things!

This is a bash script that will run clang-format -i on your code.

Features:

• Finds the right path to clang-format on Ubuntu/Debian, which encode the LLVM version in the clang-format filename
• Fixes files recursively
• Detects the most common file extensions used by C/C++ projects

Basic usage:

clang-format-all src/

Advanced usage:

clang-format-all project1/ project2/ project3/

Note: While clang-format is a powerful tool for enforcing a consistent coding standard, you should be aware that different versions of clang-format may format the same code differently. As one example that I know of, in C++ long vector or set literals (say, a dozen elements or more) in clang-format 3.7 are generally formatted with one entry per line, but under clang-format 3.5 the same literals may be formatted with multiple entries per line if the entries are short enough. Therefore if multiple people are contributing to the same project, you should strive to ensure that they're all using the same version of clang-format.
