jerd, or maybe stoa

This used to be the repo of a programming language + structured editor.

Now I'm calling it a Language Development Environment; it's an editor that you can use to incrementally create self-hosted programming languages.

Currently I'm working on a terminal-based incarnation, because I thought it would be fun, and because the constraints allow me to focus in on the core functionality. You can see an example of what it looks like here.

If you want to try out the terminal interface, you'll need two commands:

npm run ows starts the server, which manages persistence
npm run owc will start the cli client

Both use bun, which handily evaluates typescript files without any fuss.

I recommend pnpm for installing the dependencies.

The Compiler Tutorial

I've written a compiler (and type-checker) tutorial using the previous version of the Language Development Environment, which can be viewed at https://compiler.jaredforsyth.com. There's a lot of good stuff there, but I want to rewrite it entirely, and as a part of that I realized I needed to rebuild the LDE from the ground up. As one does.
