Top 9 Rust Transpiler Projects

c2rust

Migrate C code to Rust

Project mention: Converting the Kernel to C++ | news.ycombinator.com | 2024-01-10

A recent practical example of the former: the fish shell re-wrote incrementally from C++ to Rust, and is almost finished https://github.com/fish-shell/fish-shell/discussions/10123
An example of the latter: c2rust, which is a work in progress but is very impressive https://github.com/immunant/c2rust
It currently translates into unsafe Rust, but the strategy is to separate the "compile C to unsafe Rust" steps and the "compile unsafe Rust to safe Rust" steps. As I see it, as it makes the overall task simpler, allows for more user freedom, and makes the latter potentially useful even for non-transpiled code. https://immunant.com/blog/2023/03/lifting/

erg

A statically typed language compatible with Python

Project mention: Pylyzer – A fast static code analyzer and language server for Python | news.ycombinator.com | 2024-04-11

Looking through the code, Pylyzer seems to be a thin wrapper around Erg [1]. To typecheck, it converts your Python AST to an Erg AST, then runs its through the Erg typechecker and returns the errors.
Faster typechecking for Python is very much needed. But this project seems like it was built in a hackathon —- it is not a true standalone typchecker.
