This takes an absolute path to a rustc repo and adds path-dependencies that point towards the respective rustc subcrates into the Cargo.tomls of the clippy and clippy_lints crate. This allows rustc-analyzer to show proper type annotations etc on rustc-internals inside the clippy repo. Usage: cargo dev ra-setup /absolute/path/to/rust/ cc https://github.com/rust-analyzer/rust-analyzer/issues/3517 cc https://github.com/rust-lang/rust-clippy/issues/5514
