wrapmsg
wrapmsg is Go code linter. this enforces fmt.Errorf's message when you wrap error.
Example
// OK 👍🏻
if err := pkg.Cause(); err != nil {
return fmt.Errorf("pkg.Cause: %w", err)
}
// NG 🙅
if err := pkg.Cause(); err != nil {
return fmt.Errorf("cause failed: %w", err)
}
Install
$ go install github.com/Warashi/wrapmsg/cmd/wrapmsg@latest

$ go vet -vettool=$(which wrapmsg) ./...
You can also build your linter with singlechecker or multichecker. In this way, you can use --fix option to autocorrect.
package main
import (
"github.com/Warashi/wrapmsg"
"golang.org/x/tools/go/analysis/singlechecker"
)
func main() {
singlechecker.Main(wrapmsg.Analyzer)
}
