rust_lisp VS lisp

Well, the article is called "a simple Lisp", not "a fully featured Lisp". It's a demo, not a compliant implementation.

You may be interested by https://github.com/brundonsmith/rust_lisp though

So to compensate, strop will now be usable as a library. So I'm making a thing which pulls in strop as a dependency and gives you a dialect of lisp for you to specify your function in. In the future, perhaps I'll do the same with Python and maybe others. In this way, the end users will have a better way to specify what they want.

Plug: for fun I made a (less ambitious) version of this kind of thing for Rust which I ended up being pretty happy with

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.
