errscope

errscope finds code which can narrow the scope of error type.

func f() error {
  return errors.New("this is example")
}

func main() {
  err := f() // it can narrow the scope of error
  if err != nil {
    // error handling
  }
}

If you write code like below, errscope does not point out.

func main() {
  if err := f(); err != nil { // it is ok
    // error handling
  }
}

usage

$ go install gihtub.com/kimuson13/errscope/cmd/errscope@latest
$ errscope ./...

implement soon...

I want to implement the function that can ignore some result. For example

func main() {
  err := f() // ignore 
  if err != nil {
    // error handling
  }
}

This example code can narrow the scope of error type.
But corresponding line has comment such as "// ignore".
I expected that this line don't report by errscope.
