Interesting that this is in a self-developed subset/dialect of Rust called Crust which attempts to treat it as a better C, using unsafe everywhere among other things.

kzrdude•7mo ago

That's a little bit interesting. It remains then a C-like language with generics, and that sounds a lot more fun than regular C. I don't yet understand the point of avoiding references or libstd, though.

int_19h•7mo ago

Avoiding references means avoiding the borrow checker, and I don't think you can use much of stdlib if you avoid references...

lkuty•7mo ago

At the beginning of one of his videos on Crust, he's trying to avoid stdlib exactly for that reason.

IshKebab•7mo ago

I don't know why you'd see that as desirable and not use Zig. Unsafe Rust is actually harder to get right than C or Zig.

This is mainly for fun, really.

Tsoding's main lesson is how simple systems can be and the desire and demand for complex build systems is silly.

IshKebab•7mo ago

> the desire and demand for complex build systems is silly

No it isn't. "Simple" build systems like Make don't solve many of the problems that "complex" build systems like Bazel do.

At my current company I tried to convince my boss at the start of our project to use Bazel (it's very difficult to change build systems once your project is big), because I knew from experience it would solve many problems we would eventually run into.

He wouldn't let me and wanted to keep things "simple". Guess what happened? Now we have to run dozens of hours of CI just to fix a typo in a comment. CI regularly breaks because people forget dependencies. Etc.

sureglymop•7mo ago

Make is definitely not a simple system. In tsodings latest stream about this project he actually implemented a small build/test runner system for it that is really simple.

But actually I would disagree with the commenter you replied to. I think the main goal of this project seems to just be doing it for fun.

int_19h•7mo ago

I would argue that the baseline for a "simple build system" is DJB Redo.

DiabloD3•7mo ago

This is the most tsoding thing possible.

nurettin•7mo ago

I have tsoding fatigue at this point. BTW are you the DiabloD3 from freenode/#sdl like 25 years ago?

DiabloD3•7mo ago

Yep, it is me.

elvircrn•7mo ago

Had a go at this a while back: https://github.com/elvircrn/bcomp.

pveierland•7mo ago

Fun to see that it implements codegen for Uxn :)

A pretty recent work: https://github.com/sergev/BCause .

int_19h•7mo ago

Nice, but it really needs to be written in B and self-hosted.

aap_•7mo ago

Always nice to see more B. Here's mine: https://github.com/aap/b

louis771•7mo ago

Hate to see Tsoding was using Rust for this. Rust is as far removed from recreational programming than any other language.

paddw•7mo ago

I think Rust is quite a recreational language.

The least recreational languages are probably like Java,C#

renerick•7mo ago

Idk, java maybe, but c# doesn't even require .csproj files nowadays, it's really nice to use

IshKebab•7mo ago

Why? It's a great language. Very productive. Ideal for compilers too.

desumeku•7mo ago

It's not rust. It's crust. https://github.com/tsoding/crust

"The Rules of Crust

Every function is unsafe. No references, only pointers. No cargo, build with rustc directly. No std, but libc is allowed. Only Edition 2021. All user structs and enums #[derive(Clone, Copy)]. Everything is pub by default."

sureglymop•7mo ago

Is this satire or did you actually watch the streams?

He doesn't actually use rust "idiomatically". He calls this "crust":

1. Every function is unsafe

2. No references, only pointers

3. No cargo, just rustc

4. No std, only libc

...

I don't know if he is sticking to these rules throughout but that was the idea in the beginning of this project.
