Clippy Dev Tool

The Clippy Dev Tool is a tool to ease Clippy development, similar to rustcs x.py.

Functionalities (incomplete):

lintcheck

Runs clippy on a fixed set of crates read from clippy_dev/lintcheck_crates.toml and saves logs of the lint warnings into the repo. We can then check the diff and spot new or disappearing warnings.

From the repo root, run:

cargo run --target-dir clippy_dev/target --package clippy_dev \
--bin clippy_dev --manifest-path clippy_dev/Cargo.toml --features lintcheck -- lintcheck

or

cargo dev-lintcheck

By default the logs will be saved into lintcheck-logs/lintcheck_crates_logs.txt.

You can set a custom sources.toml by adding --crates-toml custom.toml or using LINTCHECK_TOML="custom.toml" where custom.toml must be a relative path from the repo root.

The results will then be saved to lintcheck-logs/custom_logs.toml.
