Extract extend codepoints out in seperate array (#713)
IsCombining() is a hotpath when rendering the screen.
Most of the time is spent doing bisearch on the word break interval list
to check it characters has the extend property.

Create a seperate table for intervals with the extend property,
so they can just be searched in isCombining().

Also some of the intervals in the word break interval list
were consecutive and could be combined to reduce the
size of the list.

This gives a ~25% performance improvement when running the benchmark

FTXUI

Functional Terminal (X) User interface

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

Feature

  • Functional style. Inspired by [1] and React
  • Simple and elegant syntax (in my opinion)
  • Keyboard & mouse navigation.
  • Support for UTF8 and fullwidth chars (→ 测试)
  • Support for animations. Demo 1, Demo 2
  • Support for drawing. Demo
  • No dependencies
  • Cross platform: Linux/MacOS (main target), WebAssembly, Windows (Thanks to contributors!).
  • Learn by examples, and tutorials
  • Multiple packages: CMake FetchContent (preferred), vcpkg, pkgbuild, conan.
  • Good practises: documentation, tests, fuzzers, performance tests, automated CI, automated packaging, etc...

Documentation

Example

    vbox({
      hbox({
        text("one") | border,
        text("two") | border | flex,
        text("three") | border | flex,
      }),

      gauge(0.25) | color(Color::Red),
      gauge(0.50) | color(Color::White),
      gauge(0.75) | color(Color::Blue),
    });

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>

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 using hbox, vbox and filler.

See also this demo.

Style

An element can be decorated using the functions:

  • bold
  • dim
  • inverted
  • underlined
  • underlinedDouble
  • blink
  • strikethrough
  • color
  • bgcolor
  • hyperlink

Example

image

FTXUI supports the pipe operator. It means: decorator1(decorator2(element)) and element | decorator1 | decorator2 can be used.

Colors

FTXUI support every color palette:

Border and separator

Use decorator border and element separator() to subdivide your UI:

auto document = vbox({
    text("top"),
    separator(),
    text("bottom"),
}) | border;

Demo:

Text and paragraph

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

To support text wrapping following spaces the following functions are provided:

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);

Table

A class to easily style a table of data.

Example:

Canvas

Drawing can be made on a Canvas, using braille, block, or simple characters:

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>

Gallery

Gallery of multiple components. (demo)

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.

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:
