ClangFormat.cmake module example

This is a minimalistic C++ project which demonstrates the use of ClangFormat.cmake module which can be found here.

Requirements

The module itself requires CMake 3.0 or higher and any version of clang-format installed. You will also need a C++ compiler for CMake to be able to generate the build system.

Usage

1. Obtain the project:

   $ git clone https://github.com/zemasoft/clangformat-cmake-example
   $ cd clangformat-cmake-example
   $ git submodule update --init --recursive

2. Generate the build system:

   $ cmake -S . -Bbuild

3. Format sources anytime using clangformat target:

   $ cmake --build build --target clangformat

   or:

   $ cd build
   $ make clangformat

4. Build the project:

   $ cmake --build build

   or:

   $ cd build
   $ make

Notes

• Sources to play with:

  • src/hello.hpp
  • src/hello.cpp
  • test/hello_test.cpp

• Format style configuration:

  • .clang-format

• If you want to use clang-format that is not on your search path, you have to supply CMake with
  -DCLANGFORMAT_EXECUTABLE=/path/to/clang-format.
