FTXUI

Functional Terminal (X) User interface

A simple C++ library for terminal based user interface.

Demo:

Feature

• Functional style.
• Simple and elegant syntax (in my opinion).
• No dependencies.

Other features

• vim navigation friendly (h,j,k,l)

Example:

  vbox(
    hbox(
      text(L"left") | border,
      text(L"middle") | border | flex,
      text(L"right") | border
    ),
    gauge(0.5) | border
  )

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