reduze VS buck2

If not: Editing the source file may lead to silent formatting jumps, which invalidate your AST. This rules out in-memory AST patching and any tracking of how the AST has been modified (you need to track AST to source locations for that). I've written about that in my another very unfinished reduction project.

Rust support is also rather good ;) https://github.com/facebookincubator/reindeer

NOTE: I won’t mention SBT and Leiningen here because, with all due respect, they are niche build tools. I also won’t discuss Kobalt for the same reason (besides, it’s no longer actively maintained). Additionally, I won’t touch upon Bazel and Buck in this context, mainly because I’m not very familiar with them. If you have insights or comments about these tools, please feel free to share them in the comments 👇

There's a new build system which works on similar ideas to buck: https://buck2.build/

I don't think all these pieces are open source yet, but https://github.com/facebook/buck2/blob/main/prelude/rust/rust-analyzer/resolve_deps.bxl is a snippet that is used to drive Rust Analyzer

We have a small example project that demonstrates what that would look like with buck2: https://github.com/facebook/buck2/tree/main/examples/bootstrap

There are a few references to NixOS on the code/issues.[0] I wonder what Meta's use case is for NixOS.
