What did you do?

After I change go 1.22 to go 1.23 in my go.mod file I have following output

$ go install -a golang.org/x/tools/cmd/stringer@latest
$ stringer -type=MessageStatus -trimprefix=MessageStatus
stringer: no value for constant MessageStatusSuccess

In case if I rollback my changes it works fine:
$ git checkout -- ../../../go.mod
$ stringer -type=MessageStatus -trimprefix=MessageStatus

What did you see happen?

I have following code:

const (
	MessageStatusSuccess MessageStatus = iota
	// All codes below are considered as errors
        ...
)

type MessageStatus uint32

I run stringer with go 1.22 specified in go.mod and it works fine. After I change it to Go 1.23 it started to fail with unclear error.

What did you expect to see?

stringer works with go 1.23

what's the go version you have outside of your module directory?
you may need to install stringer using go1 23

[olegrok]

Yes. Probably you are right. Outside the module I sill used 1.22. It can be an issue. Thanks!
