Can you provide an example of a failing command? (Edit: Sorry, you did. I just missed it.)

If you run

python example.py digestion status

you should see

Satiated.

Is that not working for you, or is it something else?

Oh, is it python example.py run that isn't working?

That command doesn't output anything, because it neither prints nor returns anything. We should update the docs so that it does something...

Edit: Yes, I see you did say that was your issue. Hope I've cleared it up now. Sorry for the misleading docs.

@dbieber Thanks for the quick response!

So calling example.py run does not actually call the Pipeline().run() method?

It does. Both ingestion.run() and digestion.run() both get called (because Pipeline().run() is called). Just nothing is displayed, since Pipeline().run() doesn't return anything (and nothing prints along the way).

If Pipeline().run() returned something, it would be displayed.

Ahh, okay I missed that those classes are returning and not printing - my bad - yep that makes sense.

Modified the example to just print and its working - derp on my part:

class Pipeline(object):

  def __init__(self):
    self.ingestion = IngestionStage()
    self.digestion = DigestionStage()

  def run(self):
    print(self.ingestion.run())
    print(self.digestion.run())

if __name__ == '__main__':
    fire.Fire(Pipeline)
