IMPORTANT: THIS PROJECT IS IN BETA STAGE & ACTIVE DEVELOPMENT
contour is a modern terminal emulator, for everyday use. It is aiming
for power users with a modern feature mindset.
- ✅ Available on all 3 major platforms, Linux, OS/X, Windows (Windows is alpha stage).
- ✅ GPU-accelerated rendering.
- ✅ Font ligatures support (such as in Fira Code).
- ✅ Unicode: Emoji support (-: 🌈 💝 😛 👪 - including ZWJ, VS15, VS16 emojis :-)
- ✅ Unicode: Grapheme cluster support
- ✅ Bold and italic fonts
- ✅ High-DPI support.
- ✅ Vertical Line Markers (quickly jump to markers in your history!)
- ✅ Blurred behind transparent background when using Windows 10 or KDE window manager on Linux.
- ✅ Runtime configuration reload
- ✅ 256-color and Truecolor support
- ✅ Key binding customization
- ✅ Color Schemes
- ✅ Profiles (grouped customization of: color scheme, login shell, and related behaviours)
- ✅ Synchronized rendering (via
DECSM 2026/DECRM 2026) - ✅ Text reflow (configurable via
DECSM 2027/DECRM 2027) - ✅ Clickable hyperlinks via OSC 8
- ✅ Clipboard setting via OSC 52
- ✅ Sixel inline images
- ✅ Terminal page buffer capture VT extension to quickly extract contents.

This is tested on Ubuntu 19.04, but any recent Linux with latest C++17 compiler should do:
sudo apt install \
"g++-9" cmake pkg-config make libfreetype6-dev qtbase5-dev libqt5gui5 extra-cmake-modules \
libfontconfig1-dev libharfbuzz-dev libfontconfig-devTo enable blur-behind feature on transparent background, you'll need the following packages:
sudo apt install libkf5windowsystem-devAnd set pass -DCONTOUR_BLUR_PLATFORM_KWIN=ON to cmake when configuring the project.
In case you want to improve performance slightly and run at at least Linux, you can add
-DLIBTERMINAL_EXECUTION_PAR=ON to the cmake configuration and make sure to have libtbb-dev
installed beforehand.
For Windows, you must have Windows 10, 2018 Fall Creators Update, and Visual Studio 2019, installed. It will neither build nor run on any prior Windows OS, due to libterminal making use of ConPTY API.
vcpkg install freetype fontconfig harfbuzz qt5-base
brew install freetype fontconfig harfbuzz boost qt5
