A mapping view to pypi projects
Project description
yp
A mapping view to pypi projects
To install: pip install yp
See also: pipoke
, for more pypi interaction tools.
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!
