Warning

This feature is still in development, and the API may change in future releases. Your contribution is needed to help us improve the compatibility and usability of C++20 modules in FTXUI. If you encounter any issues or have suggestions, please open an issue.

FTXUI provides an experimental support for C++20 modules to improve compilation times and code organization. The existing API has a module corresponding to each header.

Example with CMake and Ninja

import ftxui;

int main() {
  auto screen = ftxui::ScreenInteractive::TerminalOutput();
  auto button = ftxui::Button("Click me", screen.QuitClosure());
  screen.Loop(button);
  return 0;
}

cmake \
    -DCMAKE_GENERATOR=Ninja \
    -DFTXUI_BUILD_MODULES=ON \
    ..

ninja

Note

To use modules, you need a C++20 compatible compiler, CMake version 3.20 or higher, and use a compatible generator like Ninja. Note that Makefile generators do not support modules.
