v3.1.2

VS Code installation

It is highly recommended to install the binary compiler via the VS Code Koka extension. See the
getting started guide for more information.

Command Line Installation

Linux (x64) and macOS (x64, arm64 (M1/M2))

Tested on Ubuntu 18, 20, Debian 10, macOS Catalina (x64), and Ventura (M1), and should run on most Linux distributions.
From a command prompt, run:

curl -sSL https://github.com/koka-lang/koka/releases/download/v3.1.2/install.sh | sh

This also installs syntax highlighting for the VS Code and Atom editors. After install, run koka to verify if koka installed correctly.n

• For most installations this will ask for root access in order to install to /usr/local/bin. For more control, you can pass a different prefix. For example, installing to ~/.local instead:
  curl -sSL https://github.com/koka-lang/koka/releases/download/v3.1.2/install.sh | sh -s -- --prefix=~/.local

• To uninstall a version, use the --uninstall option:
  curl -sSL https://github.com/koka-lang/koka/releases/download/v3.1.2/install.sh | sh -s -- --uninstall

Windows 10/11 (x64)

Open a cmd prompt and download and run the installer:

curl -sSL -o %tmp%\install-koka.bat https://github.com/koka-lang/koka/releases/download/v3.1.2/install.bat && %tmp%\install-koka.bat

This will also prompt to install the clang compiler if needed, and install syntax highlighting for the VS Code and Atom editors. After install, run koka to verify if koka installed correctly.

• On Windows, the default install is to the user profile at %APPDATA%\local. You can change the installation directory using --prefix. For example:
  curl -sSL -o %tmp%\install-koka.bat https://github.com/koka-lang/koka/releases/download/v3.1.2/install.bat && %tmp%\install-koka.bat --prefix=c:\programs\local

• To uninstall a version, use the --uninstall option:
  curl -sSL -o %tmp%\install-koka.bat https://github.com/koka-lang/koka/releases/download/v3.1.2/install.bat && %tmp%\install-koka.bat --uninstall

Other platforms

You need to build from source, however Koka has few dependencies and should build from source without problems on most common platforms.
