How Our Rust-to-Zig Rewrite Is Going
The team behind the Roc programming language has reached feature parity after a 487-day project to rewrite their compiler from Rust to Zig. This milestone allows for more efficient WebAssembly output and marks a significant step toward their upcoming 0.1.0 release.
Why it matters
Compiler development is a foundational aspect of software engineering, and this rewrite highlights the ongoing trade-offs and technical preferences between modern systems programming languages.
For the past year and a half, the team building Roc 's compiler has been rewriting our 300,000 lines of Rust code into Zig , for reasons I'll recap below. We recently passed an exciting milestone: feature parity with the original compiler!
