ferret VS Carp

Seems like there has been no development since 2020 - https://github.com/nakkaya/ferret

The whole of ferret's source code is in a single org-mode file, following the literate programming style: https://github.com/nakkaya/ferret/blob/master/ferret.org

fyi there's some middle ground via ferret if you want to mix the two in the future. I think janet lang is more full featured, borrowing ideas from clojure while targeting simple embedding alongside c.

Another commenter already mentioned Gambit Scheme. That provides for inline C and therefore very easy interop with external libraries. It still has a runtime and GC though - those might pose a problem depending on your platform and task.

Ferret (https://github.com/nakkaya/ferret) and Carp (https://github.com/carp-lang/Carp) are both Lisp-like low level languages. Both seem to be fairly experimental in nature though.

> anything but C

Taking you literally, Rust and D can both compile for bare metal. D in particular has a "Better C" subset. (https://dlang.org/spec/betterc.html)

In the same vein, Terra is a C like language (manual memory management) that you metaprogram with Lua. (https://github.com/terralang/terra)

Taking you very literally, Forth is also an option.

Impressive. Wonder how the performance in Emacs will be with a file this big... org source file

Carp - https://github.com/carp-lang/Carp - "A statically typed lisp, without a GC, for real-time applications." where it's "Ownership tracking enables a functional programming style while still using mutation of cache-friendly data structures under the hood".

Looking for a personal project so open-source would be great, but maturity/production readiness is not really a factor.

The only significant thing i can find so far is https://github.com/carp-lang/Carp.

Anything notable that i might have missed ?

Not CL, but there is ulisp (http://www.ulisp.com/) for microcontrollers, supposed to be really tiny, and there is Carp (https://github.com/carp-lang/Carp) which is without a GC so seems suitable for real-time stuff.

by their powers combined

Everybody is trying to make a more user-friendly Rust. The problem is that it is not clear yet whether that's possible, and if it is, how it may look. I know Vale and have tried it, though it's extremely early to judge anything so far. It does have a much stronger theoretical background than V, but even the theory is not completely clear at this point.

There is also Carp by the way: https://github.com/carp-lang/Carp
