🚀 Cargo with less noise:

• errors have highest priority
  • they never appear in the middle of warnings
  • warnings are skipped by default until errors are fixed
  • external path dependencies' warnings are skipped by default
• all messages come in reversed order by default
  • to avoid extra scrolling
• messages are grouped by filenames
• number of messages can be limited
• after encountering first error the rest of build time is limited by default
• files can be automatically opened in your text editor on affected lines

Initially this project was a workaround for this issue, which was closed with no adequate solution.

cargo install --locked cargo-limit

cargo install --locked --force --git https://github.com/cargo-limit/cargo-limit

Run any of these in your project directory:

cargo lbench
cargo lbuild
cargo lcheck
cargo lclippy
cargo ldoc
cargo lfix
cargo lrun
cargo lrustc
cargo lrustdoc
cargo ltest

Also llcheck, llrun, etc. to auto-open text editor for warnings as well, not just for errors.

This tool is especially useful in combination with cargo-watch.
