galaxygetopt 0.9.8

Argparse Wrapper for Galaxy

You write stuff that looks like this, containing all of the information you would ever need about a tool; options, test cases, metadata

from galaxygetopt.ggo import GalaxyGetOpt as GGO
c = GGO(
    options=[
        ['int', 'An integer parameter', {'required': True, 'validate':
                                         'Int', 'default': 10}],
        ['float', 'A float', {'required': True, 'validate': 'Float',
                              'default': 1e-4}],
        ['string', 'A string value', {'required': True, 'multiple': True,
                                      'default': ['Hello', 'World'],
                                      'validate': 'String'}],

And you get data back in a nice dict

{'int': 40, 'float': '1e-4', 'string': ['Hello', 'World'] }

Known Bugs

Currently there is a known bug in the galaxy XML, under highly specific circumstances. If you define a parameter that is

• required

• hidden

• validate String (probably not a hard req)

• _galaxy_specific

and expect it to properly generate the value, it will not. See lines 206/207 of galaxygetopt/ggo.py for the current hack I use to get around this.

Other

This library features a number of subclasses of galaxygetopt.parameter.parameter, all of which have myriad numbers of options. In order to brutally test these, I have added a class galaxygetopt/tests/parameter_generator.py which can generate every single possible combination of functional calls, given rules you specify. You can then generate hundreds of objects with different sets of options, which you can filter a subset out and test at will. See that classes’s documentation for more information.
