# FTXUI

**Functional Terminal (X) User interface**

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

## Demo:
![Demo image](./examples/component/homescreen.gif)

## Feature
 * Functional style.
 * Simple and elegant syntax (in my opinion).
 * No dependencies.

## Other features
 * vim navigation friendly (h,j,k,l)

## Example:
~~~cpp
  vbox(
    hbox(
      text(L"left") | border,
      text(L"middle") | border | flex,
      text(L"right") | border
    ),
    gauge(0.5) | border
  )
~~~

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