Development

Need to install:

1. Install Python
2. Setup venv in the project folder
3. ".\venv\Scripts\activate.ps1"
4. python -m pip install conan

Clion

1. Setup venv in the project setting
2. Add conan package in setting
3. Add toolchain
4. Add CMake profile

Visual Studio 2019 (Windows)

The best way to use the CMake project with Visual Studio 2019 is to use "File > Open > Folder" to open the project folder with the main CMakeLists.txt. Use the CMakeSettings.json to add target to the project.

Ideas to implement

• Make Continuous build on github to work.
  • Update project to conan2
  • Continuous integration via GitHub Actions
• Code formatting enforced by clang-format and cmake-format via Format.cmake
• Installable target with automatic versioning information and header generation via PackageProject.cmake
• Compile on these compiler.
  • GCC
  • Clang
  • cl (Visual Studio)
  • clang-cl
• Generated and publish documentation with doxygen.
  • Automatic documentation and deployment with Doxygen and GitHub Pages
• Generate test coverage
  • coveralls
  • codecov
• Do static analysis
  • at least -Wall -Wextra -Wshadow -Wconversion -Wpedantic -Werror and -W4 on Windows
