Yes, I started off with the idea that Rue's syntax would be a strict subset of Rust's.
I may eventually diverge from this, but I like Rust's syntax overall, and I don't want to bikeshed syntax right now, I want to work on semantics + compiler internals. The core syntax of Rust is good enough right now.
Out of interest, what's the motivation? What are you hoping to do with Rue that Rust doesn't currently provide?
Primary motivation is to have a fun project. If nobody ever uses this, I'll still be happy.
I'd like fast compile times, and giving up some of Rust's lowest level and highest performance goals in exchange for it. As well as maybe ease of use.
Nice, seems like a super cool project.
I've thought a Rust like language but at Go's performance level would be interesting. Garbage collected, but compiled to a binary (no VM), but with Rust's mix of procedural and functional programming. Maybe some more capable type inference.
If you don't mind me asking, how did you get started with programming language design? I've been reading Crafting Interpreters, but there is clearly a lot of theory that is being left out there.
How is it a subset then if it has the @-prefix? Wait, does Rust's grammar still have the @ and ~ sigils from the pre 1.0 times for pointers?
It started off that way, but didn't (and won't) remain that way.
I'm using @ for intrinsics because that's how Zig does it and I like it for similar reasons to how Rust uses ! for macros.
