clang-unformat's Introduction

clang-unformat

A simple tool to infer a .clang-format file from existing code

Getting started

Build:

git clone https://www.github.com/alandefreitas/clang-unformat
cd clang-unformat
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_FLAGS=-O3 ..
cmake --build . --target clang-unformat

Make sure to compile with -DCMAKE_CXX_FLAGS=-O3. This makes a huge difference.

Run:

clang-unformat --input /path/to/source/files

Options

clang-unformat --help
clang-unformat:
  --help                       produce help message
  --input arg                  input directory with source files
  --output arg                 output path for the clang-format file
  --temp arg                   temporary directory to formatted source files
  --clang-format arg           path to the clang-format executable
  --parallel arg               number of threads
  --require-influence arg      only include parameters that influence the 
                               output
  --extensions arg             file extensions to format
