**Functional Terminal (X) User interface**

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


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

## Feature
 * Functional style. Inspired by
   [[1]](https://hackernoon.com/building-reactive-terminal-interfaces-in-c-d392ce34e649?gi=d9fb9ce35901)
   and [React](https://reactjs.org/)
 * Simple and elegant syntax (in my opinion).
 * Support for [UTF8](https://en.wikipedia.org/wiki/UTF-8) and [fullwidth chars](https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms) (→ 测试)
 * No dependencies.
 * Cross platform:
   - Linux (main target)
   - Windows (experimental, thanks to mauve@)
   - Mac (never tested, but must WORK)

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

~~~bash
┌────┐┌───────────────────────────────────────────────────────────────┐┌─────┐
