This repository contains distributed J language JOD addon source code. More information about JOD is available on The JOD Page.

The directories jod and jodsource contain the J addon code distributed by Pacman in the jod and jodsource addons.

You can get a "taste" of JOD by browsing the Jupyter notebooks.

1. JOD Introduction Lab (PDF version)
2. JOD Source Code Dump Scripts Lab (PDF version)
3. JOD Best Practices Lab (PDF version)
4. Using JOD Regular Expressions (PDF version)
5. Using JOD Backup Get (PDF version)
6. Building JOD Addons (PDF version)
7. Using jodliterate (PDF version)

JOD addon code is "compressed": whitespace and comments have been removed and safe local identifiers have been reduced to single characters. Compression significantly reduces the size of code at the expense of readability. To make casual browsing of JOD code easy, without building JOD dictionaries, the directory jodijs contains fully commented JOD source. jodijs is not distributed by Pacman.
