ftxui

FTXUI is organized into three modules, each building upon the previous:

1. ftxui/screen - Low-level rendering
2. ftxui/dom - Layout and composition
3. ftxui/component - User interaction

Alternatively, you can use the ftxui umbrella module which includes everything:

• Header: #include <ftxui/ftxui.hpp>
• CMake target: ftxui::ftxui
• Bazel target: @ftxui//:ftxui
