imtui

ImTui is an immediate mode text-based user interface library. Supports 256 ANSI colors and mouse/keyboard input.

Live demo in the browser

Even though this library is supposed to be used in the terminal, for convenience here is an Emscripten build to demonstrate what it looks like, by simulating a console in the browser:

• Demo 0: imtui.ggerganov.com
• Demo 1: hnterm.ggerganov.com
• Demo 2: wtf-tui.ggerganov.com
• Demo 3: slack.ggerganov.com

Note: the demos work best with Chrome

Details

This library is 99.9% based on the popular Dear ImGui library. ImTui simply provides an ncurses interface in order to draw and interact with widgets in the terminal. The entire Dear ImGui interface is available out-of-the-box.

For basic usage of ImTui, check one of the available samples:

• example-ncurses0
• example-emscripten0
• hnterm - a simple tool to browse Hacker News in the terminal
• wtf-tui - text-based UI for configuring the WTF terminal dashboard
• slack - text-based mock UI for Slack

Building

ImTui depends only on libncurses

Linux and Mac:

git clone https://github.com/ggerganov/imtui --recursive
cd imtui
mkdir build && cd build
cmake ..
make

./bin/imtui-example-ncurses0

Windows:

Partial Windows support is currently available using MSYS2 + MinGW + PDCurses:

# install required packages in an MSYS2 terminal:
pacman -S git cmake make mingw-w64-x86_64-dlfcn mingw-w64-x86_64-gcc mingw-w64-x86_64-pdcurses mingw-w64-x86_64-curl

# build
git clone https://github.com/ggerganov/imtui --recursive
cd imtui
mkdir build && cd build
cmake ..
make

./bin/hnterm.exe
