Detect and remove unused dependencies from Cargo.toml
in Rust projects.
Does not with dependencies from macros (yet).
cargo install cargo-shear
cargo shear --fix
The exit code gives an indication whether unused dependencies have been found:
- 0 if found no unused dependencies,
- 1 if it found at least one unused dependency,
- 2 if there was an error during processing (in which case there's no indication whether any unused dependency was found or not).
- use the
cargo_metadata
crate to list all dependencies specified in[workspace.dependencies]
and[dependencies]
- iterate through all package targets to locate all Rust files
- use
syn
to parse these Rust files and extract imports - identify the difference between the imports and the package dependencies
- make the reporting more granular for
[dependencies]
,[dev-dependencies]
and[build-dependencies]
- add tests
- print things nicely
- ignore
[package.metadata.cargo-shear] ignored = ["crate"]
