FTXUI is simple cross-platform C++ library for terminal based user interfaces!

Feature

• Functional style. Inspired by 1 and React
• No dependencies
• Cross platform.
• 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
• Learn by examples, and tutorials
• Multiple build system and packages:
• Good practices: documentation, tests, fuzzers, performance tests, automated CI, automated packaging, etc...

Example

#include <ftxui/dom/elements.hpp>
#include <ftxui/screen/screen.hpp>
#include <iostream>
 
int main() {
  using namespace ftxui;
 
  // Create a simple document with three text elements.
  Element document = hbox({
    text("left")   | border,
    text("middle") | border | flex,
    text("right")  | border,
  });
 
  // Create a screen with full width and height fitting the document.
  auto screen = Screen::Create(
    Dimension::Full(),       // Width
    Dimension::Fit(document) // Height
  );
 
  // Render the document onto the screen.
  Render(screen, document);
 
  // Print the screen to the console.
  screen.Print();
}

Expected output:

┌────┐┌────────────────────────────────────┐┌─────┐
│left││middle                              ││right│
└────┘└────────────────────────────────────┘└─────┘
