butter VS lisp

Butter has continued in development. Currently working on pretty printer so that I could test out typed ast before working on next stage: mid-level IR and lifetime analysis. It was in hiatus when I was in busy uni stuffs. But now I think I have more time now.

Hello! I've been working on Butter programming language and it's starting to get shape. Butter is heavily influenced by Rust and I want it to be concise and high-level as much as possible.

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.
