Overview

J systems are available for a number of platforms and can be installed and redistributed for free.

J is available as a base system plus optional addon packages.

The base system is the minimal system for running J applications. It includes two user interfaces:

  • Jconsole, a command-line front-end
  • JHS, a browser-based IDE

A Qt-based IDE is also available in the addons.

Once installed, all updates can be done with pacman (package manager).

J903 release

Most users should install J903.

J904 BETA

Work has already started on 904 beta and the first release will be available early in 2022.

Adventurous users should install J904.

If you already run J904-beta, then upgrade is easy:

 load'pacman'
 'upgrade'jpkg'jengine'

J902 - previous release

You are encouraged to use J903, but if you need J902, install J902.
