A mapping view to pypi projects

yp

A mapping view to pypi projects

To install: pip install yp

Example Usage

Get a mapping of all of pypi projects.

>>> from yp import Pypi
>>> p = Pypi()

The keys of this mapping are the project names. There are lots!

>>> len(p)  # doctest: +SKIP
405120
>>> 'numpy' in p and 'dol' in p
True
>>> 'no_way_this_is_a_package' in p
False

The values of the mapping are the corresponding project's info, which is a nested dict of good stuff.

>>> info = p['numpy']
>>> list(info)
['info', 'last_serial', 'releases', 'urls', 'vulnerabilities']

Tip: To only get the info you want, you'll

The project info is obtained, live, making requests to the https://pypi.python.org/pypi/{pkg_name}/json API, but the list of all project names is actually taken from a local file. You should update that file regularly (but not TOO regularly!) to be in sync with pypi.org. To do so, do this:

>>> Pypi.refresh_cached_package_names()  # doctest: +SKIP

If, on the other hand, you don't want all projects of Pypi to be the collection you're working with, you can specify what user they should belong to:

>>> p = Pypi(user='thorwhalen1')
>>> len(p)  # doctest: +SKIP
131

You can also explicitly give Pypi a collection of projects you want to work with:

>>> p = Pypi(proj_names={'numpy', 'pandas', 'dol'})
>>> len(p)
3

You can do a lot more by simply using the tools of dol to change the mapping you want to work with in all kinds of ways!
