conflicting CLI flags for clean

[pgeez]

Dear Zipline Maintainers,

Before I tell you about my issue, let me describe my environment:

Environment

• Operating System: OS X 10.12.1
• Python Version: 2.7
• Python Bitness: 64
• How did you install Zipline: conda
• Python packages: default

Now that you know a little about me, let me tell you about the issue I am
having:

Description of Issue

The CLI command zipline clean has conflicting flags for -b, --bundle and -b, --before.

(zipline-venv) pgeez$ zipline clean --help
Usage: zipline clean [OPTIONS]

  Clean up data downloaded with the ingest command.

Options:
  -b, --bundle BUNDLE-NAME  The data bundle to clean.  [default: quantopian-
                            quandl]
  -b, --before TIMESTAMP    Clear all data before TIMESTAMP. This may not be
                            passed with -k / --keep-last
  -a, --after TIMESTAMP     Clear all data after TIMESTAMP This may not be
                            passed with -k / --keep-last
  -k, --keep-last N         Clear all but the last N downloads. This may not
                            be passed with -b / --before or -a / --after
  --help                    Show this message and exit.

• What happened instead?
  Because of the conflict, -b defaults to --before.

Sincerely,
pgeez

Oops, sorry about that. Thanks for reporting this. Do you have a suggestion for a short-opt for before? I am thinking -f. Alternativly, if that is not that intuitive we could just remove the short-opt and require users to type --before.

Np.

e or f sound good to me; I really don't have an opinion. I do think, though, that you should have a short-opt for --before for the sake of consistency with other CLI args.

Hey @pgeez this should be fixed now in the latest zipline master thanks to the PR linked above ^^
