Subject: [PATCH] ob-clojure.el: Add support for babashka and nbb backend
Date: Sun, 14 Nov 2021 16:28:01 +0100	[thread overview]
Message-ID: <87bl2mycxq.fsf@kraus.my> (raw)

* lisp/ob-clojure.el: Add support for babashka and nbb backend.
---
This adds support to ob-clojure for babashka (https://github.com/babashka/babashka)
and nbb (node version of babashka).
It doesn't use `params` as I'm not really sure what they're used for and
if they're important for evaluation.

I'm also new to org development and the git email workflow so any feedback
to the code or the email patch etc is appreciated.
