cargo-dirty

A cargo subcommand that runs a user-provided Cargo command and prints a minimal summary of what was recompiled.

By default it does not forward Cargo's own output (no Fresh ... spam, no build script warnings). Instead, it:

• Streams only crates that actually did work (compile/check/build)
• Prints a final summary line (time + counts)

Install

From this repo:

cargo install --path .

Usage

Run your normal cargo command via cargo dirty:

cargo dirty check --workspace --all-targets

Stream in a more deterministic order (adds --jobs=1 to Cargo unless you already set jobs):

cargo dirty --linear check --workspace --all-targets

Show fresh crates too:

cargo dirty --show-fresh check --workspace --all-targets

Enable deep fingerprint tracing (best-effort; mainly useful for debugging):

cargo dirty --deep check --workspace --all-targets

Notes

• On success, output is intentionally terse.
• On failure, only compiler errors are printed (from Cargo JSON messages).
• Invalidation reasons are best-effort from Cargo -vv status lines (e.g. Dirty ...: ...).
