Python3 utility to generate a .clang-format file from example code-base.
Given the path to a C, C++ or Objective-C project, attempts to generate the perfect .clang-format file. It does this by producing configuration files with random variations and measuring how much code they would change. Finally the configuration file with the least change is output.
Tested under Python 3.5 using clang-format 3.9 and clang-format 3.8.
Python modules you'll need to install:
To add dependencies to a Ubuntu or Debian system:
sudo apt install clang-format python3-levenshtein python3-yaml
If Unformat is cloned into /home/abc/unformat and C++ source code is in /home/abc/my_project,
python3 /home/abc/unformat --root /home/abc/my_project /home/abc/my_project/**/*.h /home/abc/my_project/**/*.cpp
will search for the best .clang-format file.
It will start searching from /home/abc/my_project/.clang-format
and will write new configurations to that location as they are found.
