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
