digitalmars.D.bugs - [Issue 14921] New: getopt throws preventing printing of options


          Issue ID: 14921
           Summary: getopt throws preventing printing of options
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1

std.getopt.getopt can throw. What do you print in this case, since the
mechanism used to print the help is embedded in the GetOptResult that is

I think there should be a configuration option to embed in the GetOptResult the
error message instead of throwing it.

At the moment, I have an ugly workaround:

void main(string[] args)
   void callGetOpt(ref string[] a)
      getoptresult = getopt(a, ...);

   catch(Exception ex)
      callGetOpt(null); // generate the help anyway
      usage(getoptresult); // print usage
