This is a quick-n-dirty port of code I had running in another python interpreter on the App Store.

Example usage from the console is as follows:

>>> import pipista

>>> pipista.pypi_search('boto')
[{'_pypi_ordering': 156, 'version': '2.6.0', 'name': 'boto', 'summary': 'Amazon Web Services Library'}, {'_pypi_ordering': 19, 'version': '0.3', 'name': 'boto_utils', 'summary': 'Command-line tools based on Boto'}, {'_pypi_ordering': 18, 'version': '0.2', 'name': 'boto_utils', 'summary': 'Command-line tools based on Boto'}, {'_pypi_ordering': 17, 'version': '0.8.1', 'name': 'boto_rsync', 'summary': "An rsync-like wrapper for boto's S3 and Google Storage interfaces."}, {'_pypi_ordering': 17, 'version': '0.1.7', 'name': 'boto_utils', 'summary': 'Command-line tools based on Boto'}]

>>> pipista.pypi_versions('boto')
['2.6.0', '2.5.2', '2.5.1', '2.5.0', '2.4.1', '2.4.0', '2.3.0', '2.2.2', '2.2.1', '2.2.0']

>>> pipista.pypi_download('boto')

What works:

• Searching for modules
• Finding module versions
• Limiting search results
• Downloading modules (that have source versions available, not just eggs)
• Can also download a specific module version (if public)
• Can also suppress download print(..) messages (on by default)
• Creation of a new sub-directory 'pypi-modules' for storage, added to import paths

What doesn't yet work:

• Unzip / ungzip / untar of the modules
• Moving them into the correct place

The first bit (decompression) is easy - it's just late and I need some sleep.

I'm using the simple Shell gist that was pasted in here elsewhere for the time being, but I'm also in the process of porting over my personal bash-alike module which includes things like: unzip, untar, wget, environment variables, tilde/home directory, single vs. double-quote escaping, glob patterns using *[]? characters, etc.

.. The second bit is the hard bit - there's no rhyme or reason to how a particular package unpacks and installs itself. You just have to hope for the sane ones. We can't really run the included "setup.py install" scripts because they'll fall on their face in iOS. The best I'll be able to do is attempt some basic smarts - and otherwise warn the user they'll have to work with the downloaded results manually.

Maybe I can include a list of cheats for unpacking popular modules to assist with it.

Anyways, enjoy :)
