Can you run pre-commit run -a

[sebastianwebber]

is this error expected?

✦2 ❯ devenv shell

pre-commit: error: unrecognized arguments: -a

without the -a, it works:

(devenv) bash-5.2$ pre-commit

(devenv) bash-5.2$ pre-commit -a

You need to run pre-commit run -a.

[sebastianwebber]

there you go:

(devenv) bash-5.2$ pre-commit run -a
golangci-lint........................................(no files to check)Skipped
gotest...............................................(no files to check)Skipped
govet................................................(no files to check)Skipped

[domenkozar]

@sebastianwebber did you run that in examples/go env?

[sebastianwebber]

hey @domenkozar , yes, i did:

❯ pwd
/Users/seba/projetos/github.com/sebastianwebber/devenv/examples/go

❯ devenv shell
• Building shell ...
• Using Cachix: devenv
warning: creating lock file '/Users/seba/projetos/github.com/sebastianwebber/devenv/examples/go/devenv.lock'
✔ Building shell in 68.9s.
• Entering shell
(devenv) bash-5.2$ pre-commit run -a
golangci-lint........................................(no files to check)Skipped
gotest...............................................(no files to check)Skipped
govet................................................(no files to check)Skipped

Should I run the command in another folder?

please let me know how to proceed.

[domenkozar]

I got confused for a second as well, formatting had to be run at the top-level of the repo.

I've manually merged this, thank you!
