Mismatched help keys and task args doesn't result in a useful error

[sohaibfarooqi]

Hi,
I am trying to add help text to a task as follow: (Pyinvoke 0.13.0)

@task(help={'name': "Use --type aj and --type mp"})
      def build(ctx, type=None):
         pass

The issue is invoke --help build prints nothing in OPTIONS.
The check if name in self.help: (Line: 186) inside function def arg_opts() in invoke/tasks.py is getting failed and not value gets assigned to opts['help'] that's what i noticed. Any workaround for this issue?

Hm, IIRC the keys in help need to match the arguments in the task function itself, but your key is name while your argument is type.

Just checked, and my memory is correct - you need to change 'name' in help to be 'type', and then invoke --help build should show your help text on the line for --type.

Gonna leave this open as "this should have resulted in a useful error instead of silent failure", however. Thanks for the report!

Fixed in #611.
