git-cmake-format

This project aims to provide a quick and easy way to integrate clang-format into your CMake project hosted in a git repository, it consists of three elements.

• CMakeLists.txt provides the custom format target
• git-pre-commit-hook blocks commits of unformatted C/C++ files
• git-cmake-format.py is called by the format target or the pre-commit hook, it queries git for edited files, then block the commit or formats the sources

Dependencies

There are three dependencies:

• git
• python 2.7+
• clang-format

Usage

To make use of this project you can either add it as a submodule to your existing project, or copy the files into your repository. Now add the following to your CMakeLists.txt.

add_subdirectory(/path/to/git-cmake-format)

Next you can generate your build system, assuming the required dependencies are available on your path.

cd build
cmake ..

The installation of the pre-commit hook is done at CMake time during the generation of the build system, if you have followed these steps it is already installed at /path/to/your/project/.git/hooks/pre-commit.

Options
