You can install yolk with pip install yolk or via your distro's package manager, if available.
As of 0.0.7 yolk is in Gentoo's Portage tree as dev-python/yolk and a plugin for Portage named dev-python/yolk-portage. The portage plugin shows you which Python packages were installed via Portage and which were installed directly with pip (or easy_install). Check out that plugin and make one for your favorite distro. It's a great way to find Python cruft.
Yolk is a Python tool for obtaining information about installed Python packages and querying packages avilable 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
Launches your web browser at Twisted's home page
- Use yolk inside your virtualenv to see which packages are installed.
- Upgrade all installed Python packages:
Warning: You only want to do this inside a virtualenv. If you're using Linux, use your package manager to install Python packages globally whenever possible. Think twice before upgrading all packages system-wide on OSX.
