ClangFormat.cmake module

ClangFormat.cmake is a simple CMake module for clang-format support.

Requirements

The module requires CMake 3.0 or higher and some version of clang-format installed.

Integration

1. Obtain the module and add it into your project's CMake modules path:

   • Copy approach:

     $ wget https://raw.githubusercontent.com/zemasoft/clangformat-cmake/master/cmake/ClangFormat.cmake -P cmake
     

     # CMakeLists.txt
     
     list(APPEND CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake)
     

   • Submodule approach:

     $ git submodule add https://github.com/zemasoft/clangformat-cmake
     

     # CMakeLists.txt
     
     list(APPEND CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/clangformat-cmake/cmake)
     

2. Include the module:

   # CMakeLists.txt
   
   include(ClangFormat)
   

3. Setup the module:

   # CMakeLists.txt
   
   clangformat_setup(
     src/hello.hpp
     src/hello.cpp
   )
   

   or:

   # CMakeLists.txt
   
   target_clangformat_setup(sometarget)
   

Usage

1. Generate the build system:

   $ cmake -S . -Bbuild
   

2. Format sources anytime using clangformat target:

   $ cmake --build build --target clangformat
   

   or:

   $ cd build
   $ make clangformat
