This is useful! Are there other packages on MELPA that provide similar functionality?

`org-mode` has the ability to evaluate code blocks and store the output in a following results block[0].

You can configure it to run just about everything in various ways and therefore you can do Literate Programming in nearly the full Knuth sense in it.

I find it's a good solution for a local "notebook" similar to IPython/Jupyter Notebooks but for any language in Emacs.

Extending org babel to support other languages is fairly accessible. I had a lot of fun getting SwiftUI to rendering inline https://xenodium.com/previewing-swiftui-layouts-in-emacs-rev...

Also did a little experiment for Objective-C https://xenodium.com/org-babel-objective-c-support

The first link is really impressive. Amazing what can be achieved with so little code/configuration.

Org+babel is probably my favorite thing about emacs, magit being a close second.

I tried doing Literate Programming using this blog as my guide http://fgiasson.com/blog/index.php/2016/06/21/optimal-emacs-..., but I got burned out pretty quickly. I think my problem was I put literally everything in a single README.org file, and it was so taxing scrolling up and down. I might try again but with multiple org files.

Org mode provides a supercharged version of this functionality that will work for any language as long as you can point it to an appropriate runtime. It's definitely a little more verbose, since you have to declare the language and stuff inside the org mode syntax, but I'm sure that you could get it to work ad-hoc with a little hacking.

There is lively.el [1]! It is also on MELPA in a more recent version [2]. It allows to put an elisp expression into any buffer and then replaces that with the output in a time interval or manually. I use that frequently.

https://blog.sulami.xyz/posts/literate-calc-mode/ is pretty nice. I always have literate-calc-minor-mode (+org-mode as major) in my scratch buffer for quick calculations.
