The try.docopt.org site does not process repeating positional arguments properly

[harijay]

Hi This is an issue in only the browser based trial. For a command like

Usage:
pdb_prepare ... --ref=reference.pdb [--desc]"

If you give the above doc string repeat arguments to test it with for eg.

file1.pdb file2.pdb file4.pdb --ref=test.pdb

The result displayed in the browser has the file positional argument without any spaces.

"": "file1.pdbfile2.pdbfile4.pdb"}

Instead of

'': ['file1.pdb', 'file2.pdb', 'file4.pdb'],

Not an issue with the actual module though.

That's true. Thanks for reporting. So far I haven't figured where's the problem.

So apparently docopt doesn't work well when argv is a unicode string. I'm pushing a quick fix to this repo, but I need to think more about if it is a problem for docopt itself.

Was the error only in the webapp?

Nope, the error is in docopt as well:

Python 2.7.3 (default, Dec 17 2012, 20:20:42) 
[GCC 4.2.1 Compatible Apple Clang 4.1 ((tags/Apple/clang-421.11.66))] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from docopt import docopt
>>> docopt('usage: prog <a>...', 'a b c')
{'<a>': ['a', 'b', 'c']}
>>> docopt('usage: prog <a>...', u'a b c')
{'<a>': u'abc'}
>>> docopt('usage: prog <a>...', ['a', 'b', 'c'])
{'<a>': ['a', 'b', 'c']}
>>> docopt('usage: prog <a>...', [u'a', u'b', u'c'])
{'<a>': u'abc'}

But the error manifests itself only when docopt is passed unicode strings, which does not happen at the command line.
