Instance Method Details

#do_close(id = nil) ⇒ Object

The user doesn’t have to give us an event ID. If no event name is given, we’ll pop the last event off the stack. If an event name is given and it doesn’t look like a full WF event name, we’ll look for something on the stack. If it does look like a real event, we’ll make and API call straight away.

#do_create(opts = nil) ⇒ Object

You can override the options generated by docopt. This is how #wrap() works.
