Golang go/scanner.ErrorList type usage examples
Example 1:
switch err := err.(type) {
case types.Error:
posn := a.prog.Fset.Position(err.Pos)
errors[posn] = append(errors[posn], err.Msg)
case scanner.ErrorList:
for _, e := range err {
errors[e.Pos] = append(errors[e.Pos], e.Msg)
}
Example 2:
func report(err error) {
scanner.PrintError(os.Stderr, err)
if list, ok := err.(scanner.ErrorList); ok {
errorCount += len(list)
return
}
errorCount++
}
