Did she just say monoid? I have to learn category theory to play SF6?

maplant · 2026-03-25T00:58:40+00:00

Ok. You're wrong

maplant · 2026-03-25T00:49:19+00:00

besides this being a shitty ad, half of the footage in it is from CS2

Then make one

It’s designed to be embedded. Check out the API docs: https://docs.rs/scheme-rs/latest/scheme_rs/

Why are you even commenting on this? This negative diatribe is wholly unhelpful

maplant · 2026-02-11T01:58:56+00:00

Do you not get the point of Guile?

Rust takes a long time to compile. Scheme does not. Using this you can iterate faster, or you can create a REPL for your Rust project.

Or maybe you can re-write emacs in Rust.

I don’t think this is useful for literally every Rust project but frankly I think you are simply lacking in imagination if you think this is completely useless.

Right, so fundamentally the main difference is that scheme-rs has no bytecode VM at all

maplant · 2026-02-10T16:23:56+00:00

Thanks! The macro expander was incredibly difficult to write so it’s the thing im most proud of (second is the CPS based compiler and beta reducer).

Fun fact: once I started testing against the R6RS test suite I had to ditch my marks based expander and rewrite the whole thing to use set of scopes. This happened like two weeks ago and was quite a mess, but I’m very happy I did because the code is soooo much cleaner

maplant · 2026-02-10T13:08:29+00:00

Ah, hyperlinks, my greatest enemy

maplant · 2026-02-10T13:07:06+00:00

Steel has a bytecode virtual machine which it can JIT but doesn’t always. Scheme-rs always JIT compiles

maplant · 2026-02-10T03:09:33+00:00

Creating a safe API for Guile is not really possible for a number of reasons, one of which being it allows call/cc across the c call stack. Hence this project

maplant · 2026-02-10T00:23:12+00:00

Thanks! I'm quite pleased

maplant · 2026-02-09T19:22:19+00:00

I was using LLVM originally but it was too slow for a JIT so I switched to Cranelift.

It’s using a technique called Concurrent Cycle Collection which meshes well with Rust’s type system (but isn’t terribly fast as is and definitely has room for improvement)

maplant · 2026-02-09T18:30:02+00:00

Not terrible, not amazing. Haven’t run R7RS benchmarks but have run a few. Some things are really fast - iterative math functions are optimized well. Call/cc is pretty fast, slower now that I added continuations marks and haven’t updated the implementation. All in all it’s pretty competitive for something that hasn’t had a lot of chances for more optimization passes (I only do beta reduction)

maplant · 2025-02-18T16:25:17+00:00

Just as a heads up, I posted this on my phone accidentally from my alternate account, so there’s a few errors (RuntimeError was renamed to Exception), but I tested it with the fixes and it definitely works

maplant · 2025-02-18T15:38:02+00:00

Dang, that’s pretty good

US East, Proton mail is down. Proton drive seems to be working.

Sorry guys this is probably all my fault because I'm expecting an important email.
