## FTXUI
Functional Terminal (X) User interface
A simple 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/) (preferred), vcpkg, pkgbuild, conan.
* Good practises: documentation, tests, fuzzers, performance tests, automated CI, automated packaging, etc...

#### 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 [](https://arthursonzogni.github.io/FTXUI/elements_8hpp_source.html
)
Layout
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`.

[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2gridbox_8cpp-example.htmlp) using gridbox:

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

[See](https://arthursonzogni.github.io/FTXUI/examples_2dom_2hflow_8cpp-example.html) also this [demo](https://arthursonzogni.github.io/FTXUI/examples/?file=component/flexbox).
Style
An element can be decorated using the functions:
- `bold`
- `dim`
- `inverted`
- `underlined`
- `underlinedDouble`
- `blink`
- `strikethrough`
- `color`
- `bgcolor`
[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2style_gallery_8cpp-example.html)

FTXUI supports the pipe operator. It means: `decorator1(decorator2(element))` and `element | decorator1 | decorator2` can be used.
Colors
FTXUI support every color palette:
Color [gallery](https://arthursonzogni.github.io/FTXUI/examples_2dom_2color_gallery_8cpp-example.html):

Border and separator
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):

Text and paragraph
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);
```
[Paragraph example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2paragraph_8cpp-example.html)

Table
A class to easily style a table of data.
[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2table_8cpp-example.html):

Canvas
Drawing can be made on a Canvas, using braille, block, or simple characters:
Simple [example](https://github.com/ArthurSonzogni/FTXUI/blob/master/examples/dom/canvas.cpp):

Complex [examples](https://github.com/ArthurSonzogni/FTXUI/blob/master/examples/component/canvas_animated.cpp):

#### 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 [](https://arthursonzogni.github.io/FTXUI/component_8hpp_source.html)
Gallery
[Gallery](https://arthursonzogni.github.io/FTXUI/examples_2component_2gallery_8cpp-example.html) of multiple components. ([demo](https://arthursonzogni.github.io/FTXUI/examples/?file=component/gallery))

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()
```
