orion VS lisp

Code and documentation are here: https://github.com/orion-lang/orion

When my language VM will be finished, I plan to make this project a library of it. It is not a real LISP, I picked the syntax in Scheme and concepts from OCaml, but I think it could be good for that use case.

Might be because it uses a tree-walking interpreter.

If I am reading the source right, it copies everything, which is not really beneficial for performance.

I've been curious about https://github.com/ezekiiel/lust but I don't know its status as a project

Since last month I've been working on garbage collection and string handling in my Lisp compiler. I've found writing the garbage collector to be hard but strings are fun :)

I just added variable-arity functions to my lisp which compiles to Cranelift. I was blocked for a while trying to work out how to convince Cranelift to put arguments on the stack but eventually gave up and I now heap allocate a location for function arguments. It's not great for performance but it feels great to have finally finished it!

I’ve been carrying on working on compiling my lisp this month. It’s been a fun couple weeks because I’ve finally gotten to the fun stuff like higher order functions, closures, and adding the ability to call into libc.
