Template For C Projects

This is a template for C projects. What you get:

• Library, executable and test code separated in distinct folders.
• Use of modern CMake for building and compiling.
• External libraries fetched by CMake or cloned by Git.
• Unit testing using Unity
• General purpose libraries:
  • log
  • argparse
• Continuous integration testing with Github Actions.
• Code coverage reports, including automatic upload to Codecov.
• Code documentation with Doxygen.

Library code goes into src/, main program code in app/ and tests go in tests/.

Software Requirements

• CMake 3.16+
• GNU Makefile
• Doxygen
• Conan or VCPKG
• MSVC 2017 (or higher), GCC 9 (or higher), Clang 9 (or higher)
• Code Coverage (only on GNU|Clang): lcov, gcovr

Building

First, clone this repo and do the preliminary work:

git clone --recursive https://github.com/franneck94/CProjectTemplate
make prepare

• App Executable

cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build . --config Release --target main
cd bin
./main

• Unit testing

cd build
cmake -DCMAKE_BUILD_TYPE=Debug ..
cmake --build . --config Debug --target unit_tests
cd bin
./unit_tests

• Documentation

cd build
cmake -DCMAKE_BUILD_TYPE=Debug ..
cmake --build . --config Debug --target docs

• Code Coverage (Unix only)

cd build
cmake -DCMAKE_BUILD_TYPE=Debug -DENABLE_CODE_COVERAGE=ON ..
cmake --build . --config Debug --target coverage
