  Usage:

    contour [terminal] [config FILE] [profile NAME] [debug TAGS] [live-config] [dump-state-at-exit PATH]
                       [early-exit-threshold UINT] [working-directory DIRECTORY] [class WM_CLASS]
                       [platform PLATFORM[:OPTIONS]] [session SESSION_ID] [PROGRAM ARGS...]
    contour font-locator [config FILE] [profile NAME] [debug TAGS]
    contour help
    contour version
    contour license
    contour parser-table
    contour list-debug-tags
    contour generate terminfo to FILE
    contour generate config to FILE
    contour generate integration shell SHELL to FILE
    contour capture [logical] [words] [timeout SECONDS] [lines COUNT] to FILE
    contour set profile [to NAME]

It's best installed from supported package managers, but if you want to build from source, it is recommended to execute the scripts/install-deps.sh script.

./scripts/install-deps.sh

This script might ask you for the administrator password if a package dependency can be insalled via the system package manager.

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.

.\scripts\install-deps.ps1

cmake -S . -B build
cmake --build build/

# Optionally, if you want to install from source
cmake --build build/ --target install
