sub flag

[keith6014]

is it possible to have a subflag?

Usage: main <path>

Arguments:
  <path>    paths and paths

Flags:
  -h, --help           Show context-sensitive help.
      --verbose        Verbose
      --read=STRING
          --ascii
          --binary

When I do
command --read file i would like to specify either --ascii or --binary
something like

command --read "file.xef" --ascii

Try this:

Ascii bool `required:"" xor:"format"`
Binary bool `required:"" xor:"format"`

Thanks. How do I set default as Ascii? When I try setting it I get can't be used together.
