J Addons User Guide Developer Guide Addons Reference


Add-ons are developer contributed extensions of the J language. They are packages which are stored in Git repositories and are brought in through the Package Manager. Add-ons can then be loaded into the J session to increase the functionality of the language. You can use existing addons or create new ones for others to use.

User Guide

The User Guide section provides instructions on how to use the package manager as well as the different categories of addons that are available to the user.

Developer Guide

A comprehensive guide to developing add-ons for use by others. This is an area that is currently under development, but our goal is to make it easier to create addons in J. Any suggestions that would make the explanation better or the process easier are welcome.
