I keep bouncing the idea around of building a core in C or Rust then writing everything atop it using Janet. I love how readable lisps are (with macros, you can really move up the abstraction ladder quickly) and working on a live image should make iteration a breeze in an LLM.

I built a OCaml core with a webserver - then made my scripting language on top a custom scheme. I love your idea! I think you would find that a solid interpreted language living in a webserver is an extremely useful think to have. Let me know if you build it!

What did you write with your webserver? Hosting a personal blog? I'm thinking of a good usecase for this. I'm thinking about a game of some sort but not sure yet.

I've just been dogfooding whatever I can to build it out.

Webpages, zettelkasten, todo, workout, diet tracker. It's a web framework! Creating an endpoint is just like making a function in emacs.

Since lisp is homoiconic the AST is just raw JSON. I save the AST in JSON stores in Postgres. But you can clone the AST down and then eval against a local copy of the REPl. So you get local eval for free.

Of course you have to rebuild git to manage a branching REPL in this way.

That works great. The compiler language doesn't matter that much but your language needs a 'runtime' and that is much less annoying to write in C (possibly with bits of assembly, depending on what you're doing) than almost anything else. To a good approximation, your 'compiler' or 'interpreter' amounts to mapping your real language onto a sequence of function calls backed by the 'runtime'.

Interesting take and similar to something I've recently been working on. Have a look at janet-num.[1] Plain numeric C kernels under Janet.

Janet for orchestration, C for the frame loop.

Check out https://codeberg.org/veqq/varray implementing APL primitives on tarray (so should be a magnitude faster than the cffi approach), which powers https://codeberg.org/veqq/declarative-dsls which exposes a fair bit of statistics stuff (I have a financial analysis library built on top of it in prod, which I'll try to open source soon) besides logic features

There is also https://codeberg.org/zzkt/deft/ for typing things.

And spork/sh does sh
