$ pip install --upgrade yolk3k

Yolk is a Python tool for obtaining information about installed Python packages and querying packages available on PyPI (Python Package Index).

You can see which packages are active, non-active or in development mode and show you which have newer versions available by querying PyPI.

Usage Examples:

$ yolk -l
    List all installed Python packages

$ yolk -a
    List only the activated packages installed (Activated packages are
    normal packages on sys.path you can import)

$ yolk -n
    List only the non-activated (--multi-version) packages installed

$ yolk -l -f License,Author nose==1.0
    Show the license and author for version 1.0 of the package `nose`

$ yolk --entry-map nose
    Show entry map for the nose package

$ yolk --entry-points nose.plugins
    Show all setuptools entry points for nose.plugins

These options query PyPI:

$ yolk -U pkg_name
    Shows if an update for pkg_name is available by querying PyPI

$ yolk -U
     Checks PyPI to see if any installed Python packages have updates
     available.

$ yolk -F Paste
    Download source tarball for latest version of Paste to your current
    directory

$ yolk -F Paste -T svn
    Do a subversion checkout for Paste to a directory named Paste_svn in
    your current directory.

$ yolk -L 2
    Show list of CheeseShop releases in the last two hours

$ yolk -C 2
    Show detailed list of changes in the CheeseShop in the last two hours

$ yolk -M Paste==1.0
    Show all the metadata for Paste version 1.0

$ yolk -M Paste
    Show all the metadata for the latest version of Paste listed on PyPi

$ yolk -D cheesecake
    Show all (source, egg, svn) URL's for the latest version of cheesecake
    packages

$ yolk -T source -D cheesecake
    Show only source code releases for cheesecake

$ yolk -H twisted
