The Tooling

In this post I'm going to get set up with the playground tooling I'll use to showcase the languages I discuss here. The goal is to have something similar to a Jupyter notebook: a series of executable text-editor fields that share an environment.

For this example, I'll be using a simple custom lisp. The details of the language aren't important for this post, but you can find the repo here.

Here is a playground:

All playgrounds for the same language in the same file share the same environment, so you can use defines from one in the others (after they've been run).

For normal results, the playground will show the result and give a green check to indicate the listing has been run. If there's an error, the playground will show the error in red and have an X:

Typing in any field will clear the status. Refreshing the page will reset the environment.
