Global positional value arguments don't work after subcommands #61

Closed topjor closed 4 years ago

topjor commented 4 years ago

I am trying to have some global positional values after subcommands as these are the same for each command but when parsing flags and entering a value at the positional place I always get an Unexpected argument: <value> exception

It works fine when using them under a subcommand but not globally

Global positional values also dont show up under the help of a subcommand

Oh, a positional actually cant be a global. The positional is in relativity to some subcommand (or the root program) like this:

./myProgram someSubcommand [positional value goes here]

This above positional would only be available after someSubcommand. If it were available from the root, we wouldn't be able to tell if that were a subcommand of some kind or a positional value.

You have to add positional values on every subcommand that has them.

I'm going to close this one - if I am not understanding or if you think something is busted, feel free to leave a reply.
