Kill your Dead Code with Fire!
summary
Hank is an open‑source tool that detects and removes oxbow and dead code across large Erlang projects by running as a rebar3 plugin and analyzing ASTs; it flags unused macros, record fields, config keys and consistently ignored function arguments, is extensible with custom rules, and aims to be never wrong (may miss cases but should not produce false positives). Early runs find surprising scale: 1,000+ unused macros and 200+ unused record fields in OTP, plus seven in a carefully maintained repo; configure ignores in rebar.config or per‑module.
