Feature Request: Run shell commands on cargo command failures
Currently, shell commands only run after cargo commands run successfully. I'd also like to be able to run a different shell command on cargo command failures. My use case is that I'd like to run a command that plays a success sound on a cargo command success, and a different sound on cargo command failure.
This is what I have right now:
cargo watch -x check -s "afplay ~/bin/success-chime.mp3 & echo ''"
This is what I'd like to see. I'm not sure that this would be the right syntax, but I think it gets the point across:
cargo watch -x check -s "afplay ~/bin/success-chime.mp3 & echo ''" --cargo-failure "afplay ~/bin/error-chime.mp3 & echo ''"
The -s arg gets run after the previous cargo commands pass, and the --cargo-failure arg gets run if cargo doesn't complete successfully.
What should the syntax here be?
Right now what you should do is
cargo watch -s 'cargo check && success || failure'
where success and failure are the chimes commands you've defined
