Question

As ConsoleFx seems to be progressing too slow (bummer, it had much potential) and showing too many breaking changes every build, I decided to switch to Mono.Options for my commandline parsing needs.

My OptionSet is built in the following method

private static OptionSet BuildOptionSet()
{
    OptionSet optionSet = new OptionSet()
        .Add("?|help|h", "Prints out the options", option => help = option != null)
        .Add("w|wait", "Waits for any key after finished processing", option => wait)
    return optionSet;
}

All tutorials I find, deal with options and how to capture them, but arguments are never mentioned.

The following call for example

   c:\>test.exe brandCode1 brandCode2 /w

Should put wait on true and give me two arguments with values brandCode1 and brandCode2.
How can I capture them in a clean way from the args[] ?

Is this not possible with Mono.Options?

From what I can tell from reading the docs, you need to call OptionSet‘s parse method at some point. When you do, it processes your actions and returns “A List<string> containing all unhandled arguments.”

Unfortunately, you also need to pass it the main method’s argument to get this to work.

List<string> extra = optionSet.Parse(args);
