# FTXUI

<i>Functional Terminal (X) User interface</i>

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

## 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)
 * Keyboard & mouse navigation.
 * Support for [UTF8](https://en.wikipedia.org/wiki/UTF-8) and [fullwidth chars](https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms) (→ 测试)
 * Support for animations. [Demo 1](https://arthursonzogni.github.io/FTXUI/examples/?file=component/menu_underline_animated_gallery), [Demo 2](https://arthursonzogni.github.io/FTXUI/examples/?file=component/button_style)
 * Support for drawing. [Demo](https://arthursonzogni.github.io/FTXUI/examples/?file=component/canvas_animated)
 * No dependencies
 * **Cross platform**: Linux/MacOS (main target), WebAssembly, Windows (Thanks to contributors!).
 * Learn by [examples](#documentation), and [tutorials](#documentation)
 * Multiple packages: CMake [FetchContent]([https://bewagner.net/programming/2020/05/02/cmake-fetchcontent/](https://cmake.org/cmake/help/latest/module/FetchContent.html)) (preferred), vcpkg, pkgbuild, conan.
 * Good practises: documentation, tests, fuzzers, performance tests, automated CI, automated packaging, etc...

## Short gallery

#### DOM

This module defines a hierarchical set of Element. An element manages layout and can be responsive to the terminal dimensions.

They are declared in [<ftxui/dom/elements.hpp>](https://arthursonzogni.github.io/FTXUI/elements_8hpp_source.html
)
  
<details><summary>Layout</summary>

Element can be arranged together:
  - horizontally with `hbox`
  - vertically with `vbox`
  - inside a grid with `gridbox`
  - wrap along one direction using the `flexbox`.
  
Element can become flexible using the the `flex` decorator.
  
[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2vbox_hbox_8cpp-example.html) using `hbox`, `vbox` and `filler`.

![image](https://user-images.githubusercontent.com/4759106/147242524-7103b5d9-1a92-4e2d-ac70-b3d6740061e3.png)
  
  
[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2gridbox_8cpp-example.htmlp) using gridbox:

![image](https://user-images.githubusercontent.com/4759106/147242972-0db1f2e9-0790-496f-86e6-ed2c604f7a73.png)

[Example](https://github.com/ArthurSonzogni/FTXUI/blob/master/examples/dom/hflow.cpp) using flexbox:

![image](https://user-images.githubusercontent.com/4759106/147243064-780ac7cc-605b-475f-94b8-cf7c4aed03a5.png)

[See](https://arthursonzogni.github.io/FTXUI/examples_2dom_2hflow_8cpp-example.html) also this [demo](https://arthursonzogni.github.io/FTXUI/examples/?file=component/flexbox).

</details>

<details><summary>Style</summary>

An element can be decorated using the functions:
  - `bold`
  - `dim`
  - `inverted`
  - `underlined`
  - `underlinedDouble`
  - `blink`
  - `strikethrough`
  - `color`
  - `bgcolor`
  - `hyperlink`

[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2style_gallery_8cpp-example.html)

![image](https://user-images.githubusercontent.com/4759106/147244118-380bf834-9e33-40df-9ff0-07c10f2598ef.png)
  
FTXUI supports the pipe operator. It means: `decorator1(decorator2(element))` and `element | decorator1 | decorator2` can be used.
  
</details>

<details><summary>Colors</summary>

FTXUI support every color palette:

Color [gallery](https://arthursonzogni.github.io/FTXUI/examples_2dom_2color_gallery_8cpp-example.html):
![image](https://user-images.githubusercontent.com/4759106/147248595-04c7245a-5b85-4544-809d-a5984fc6f9e7.png)

</details>
  
<details><summary>Border and separator</summary>

Use decorator border and element separator() to subdivide your UI:
  
```cpp
auto document = vbox({
    text("top"),
    separator(),
    text("bottom"),
}) | border;

```

[Demo](https://arthursonzogni.github.io/FTXUI/examples_2dom_2separator_8cpp-example.html):
  
![image](https://user-images.githubusercontent.com/4759106/147244514-4135f24b-fb8e-4067-8896-bc53545583f7.png)
  
</details>

<details><summary>Text and paragraph</summary>

A simple piece of text is represented using `text("content")`.

To support text wrapping following spaces the following functions are provided:
```cpp
Element paragraph(std::string text);
Element paragraphAlignLeft(std::string text);
Element paragraphAlignRight(std::string text);
Element paragraphAlignCenter(std::string text);
Element paragraphAlignJustify(std::string text);
```

</details>

<details><summary>Table</summary>

</details>

<details><summary>Canvas</summary>

</details>

#### Component

The ftxui/component is needed when you want to produce dynamic UI, reactive to the user's input. It defines a set of ftxui::Component. A component reacts to Events (keyboard, mouse, resize, ...) and Render Element (see previous section).

Prebuilt components are declared in [<ftxui/component/component.hpp>](https://arthursonzogni.github.io/FTXUI/component_8hpp_source.html)

<details><summary>Gallery</summary>

## External package

It is **highly** recommended to use CMake FetchContent to depend on FTXUI. This
way you can specify which commit you would like to depend on.
```cmake
include(FetchContent)

FetchContent_Declare(ftxui
  GIT_REPOSITORY https://github.com/ArthurSonzogni/ftxui
  GIT_TAG v3.0.0
)

FetchContent_GetProperties(ftxui)
if(NOT ftxui_POPULATED)
  FetchContent_Populate(ftxui)
  add_subdirectory(${ftxui_SOURCE_DIR} ${ftxui_BINARY_DIR} EXCLUDE_FROM_ALL)
endif()
```

If you don't, the following packages have been created:
- [vcpkg](https://vcpkgx.com/details.html?package=ftxui)
- [Arch Linux PKGBUILD](https://aur.archlinux.org/packages/ftxui-git/).
- [conan.io](https://conan.io/center/ftxui)
- [openSUSE](https://build.opensuse.org/package/show/devel:libraries:c_c++/ftxui)
