              Functional Terminal (X) User interface
              
              A simple C++ library for terminal based user interfaces!
              Feature
              - Functional style. Inspired by [1] and React
              - Simple and elegant syntax (in my opinion)
              - Keyboard & mouse navigation.
              - Support for UTF8 and fullwidth chars (→ 测试)
              - Support for animations. Demo 1, Demo 2
              - Support for drawing. Demo
              - No dependencies
              - Cross platform: Linux/MacOS (main target), WebAssembly, Windows (Thanks to contributors!).
              - Learn by examples, and tutorials
              - Multiple packages: CMake FetchContent (preferred), vcpkg, pkgbuild, conan, nix, etc...
              - Good practises: documentation, tests, fuzzers, performance tests, automated CI, automated packaging, etc...
