Package: yolk
ContentsInstallationSummaryTips and TricksChangesRequirementsInstallationYou can install yolk withpip install yolkor 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.SummaryYolk 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

$ yolk --entry-map nose

$ yolk --entry-points nose.plugins
     Show all setuptools entry points for nose.pluginsThese options query PyPI:$ yolk -U pkg_name
     Shows if an update for pkg_name is available by querying PyPI

 $ yolk -H twisted
     Launches your web browser at Twisted's home pageTips and TricksUse 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.$ pip install -Uyolk -U | awk ‘{print $1}’Changes0.4.3: Added missing documentation and license files0.4.2: Fix for -C when an integer isn’t suppliedFix for –entry-map from Jesus Rivero (Neurogeek)neurogeek@gentoo.org. Thanks, Jesus!Switch to BSD license from GPL-20.4.1: Fix for -f fieldsAdd check for integer with -L0.4.0: Added http proxy support for XML-RPCAdded case-insensitive search for -fNon-existent packages with -S no longer show entire index (bug was with PyPI)Fixed exception when package has no metadata0.3.0: Added -C and -L options for new PyPI XML-RPC methodschangelogandupdated_releasesAlways check package name cache on disk before querying PyPi to see if a package exists and has proper case.Added -F option to download source, egg or subversion checkouts.Removed -L RSS feed option because the newupdated_releasesXML-RPC method is much nicerFixed ‘-D -T egg’ so it won’t return source if no egg is availableMajor refactoring.Removed dependency on elementtree0.2.0: Added ‘svn’ type for -TA kablillion bug fixes0.1.0: You can now use -f with -MMore accurate URL’s with -D using pipAbility to check for a single package with -UUses std Python logging moduleFixed bug so we have correct exit codes0.0.7: New options: –entry-map and -entry-pointsImproved results with –download-linksNew plugin system. First plugin available: yolk-portage
for Gentoo Linux.-v option is now –version-v is now a new option: –verboseMany bug fixes.0.0.6: Fix Windows problem which showed all pkgs in develop modeon some systems.Fix bad interpreter shebang in rss_feed.py exampleStart using nose unit tests from setup.pyUse restructuredtext in docstrings0.0.5: Show packages installed in ‘development’ mode.Improved output of -l, -n and -a. You can get the previous (<=0.0.4)
output by adding ‘-f Summary’More sanity checking for various options.Don’t throw exception if there is no package metadata0.0.4: Added -U option to query PyPI for new versions of packages you haveinstalledRequirementssetuptools (Distribute preferred)elementtree (For RSS feed option extra_requires [RSS]) (included in Python >=2.5)
