Define a good command line interface

[apmcleod]

That's a general problem that we need to discuss and solve together. Does it even make sense to allow for arbitrary pipelines using the command line?

My suggestion would be, instead, to offer a well-defined set of commands such as dimcat bigrams and define the possible pipelines for it. The various combinations of groupers and slicers could then be distributed between

• general arguments available for all commands (such as Corpus grouper) and
• specific arguments share between those commands where they apply.

P.S.: Not even sure argparse is actually able to capture the difference in order in your example.
