The current version on the branch has support for child Options: addChild(Option) addChildren(Set)
I think that this is too restrictive and the correct support should be: addOptions(Options)
This will allow the following style command line:
app -option -x|-y
The definition for this is:
// build child options
Option x = builder.withName("x").create();
Option y = builder.withName("y").create();
ExclusiveGroup axis = new ExclusiveGroup();
axis.add(x);
axis.add(y);
Options child = new Options();
child.add(axis); // build option
Option option = builder.withName("option").create();
option.setOptions(child);// build application options Options options = new Options(); options.add(option);
This means that if "-option" is found in the command line arguments, parse the remaining arguments using the Options specified for 'option'. In this case, the only valid remaining arguments are "-x" or "-y", but not both.
If I don't hear any reasons why people think this approach is incorrect (or any other significant comments) I will proceed to implement it.
