Clay

Clay is a REPL-friendly Clojure tool for data visualization and literate programming.

It also offers a set of tools to integrate Clojure literate programming with the Quarto publishing system.

Docs

More details may be found in the Documentation. In particular:

• See the API and Configuration subsections for more options and variations.
• See the Setup section and recent Videos for details about integrating Clay with your editor so you do not need to call make! yourself.

The Claykind project is rethinking the Clay architecture and implementation from scratch, in a new code base. Currently (Fall 2023), the two projects are being developed in coordination.

The clay.el Emacs package offers relevant interactive functions to use Clay from Emacs

Kindly is a common ground for defining how things should be visualized, seeking compatibility across tools.

kindly-advice is a library that helps tools such as Clay to be Kindly-compatible.

kindly-render is a library for rendering kinds to different taget formats. In the near future (as of Nov. 2024), Clay should rely on it.

read-kinds is used internally by Claykind (and soon by Clay as well) to generate Kindly advice from notebooks expressed as Clojure namespaces.
