Make egg metadata information available for Debian packaging

Project description

Tools for introspecting Python package metadata and translating the resulting information into Debian metadata. This information is translated:

  • Setuptools version numbers to Debian format that sorts correctly

  • Setuptools package names to Debian binary and source package names

  • Setuptools dependencies to Debian dependencies

This package provides a van-pydeb binary which provides a way to access the information from shell scripts. A python based API is also available for python programs to use.


To extract the dependency info of this package, one can run the following command after setting up buildout:

$ ./bin/van-pydeb depends --egg-info van.pydeb.egg-info
python-setuptools, python-van

This information can then used in a debian/rules file as follows:

(echo -n 'setuptools:Depends=' && van-pydeb depends --egg-info debian/$(PACKAGE)/usr/lib/python$*/site-packages/$(EGG_NAME).egg-info) >> debian/$(PACKAGE).substvars

There ary many different methods of using this command, such as getting the dependencies (including the extra dependencies) of the package:

van-pydeb depends --egg-info debian/$(PACKAGE)/usr/lip/python$*/$(EGG_NAME).egg-info

Or, the dependencies of an extra:

van-pydeb depends --egg-info debian/$(PACKAGE)/usr/lip/python$*/$(EGG_NAME).egg-info --extra $(EXTRA)

The dependencies of 2 extras:

van-pydeb depends --egg-info debian/$(PACKAGE)/usr/lip/python$*/$(EGG_NAME).egg-info --extra $(EXTRA) --extra $(EXTRA2)

The dependencies of a package excluding the dependencies of extras:

van-pydeb depends --egg-info debian/$(PACKAGE)/usr/lip/python$*/$(EGG_NAME).egg-info --exclude-extra $(EXTRA1) --exclude-extra $(EXTRA2)


The code for van.pydeb is housed in subversion at


1.3.3 (2011-08-10)

  • Generate separate dependencies when both extra and version requirements are specified (

  • py_to_bin_default: do not prepend python- if python package name already starts with it.

  • Update automatically updated list from current unstable.

  • setuptools comes from distribute source package.

1.3.2 (2010-06-22)

  • Conform to Zope repository policy.

  • Update automatically updated list from current unstable.

  • Ignore python3 packages for now in auto-generated list.

1.3.1 (2010-01-14)

  • Add override for python-gettext.

  • Add override for Chameleon (python-chameleon).

  • Update automatically updated list from current unstable.

1.3.0 (2009-09-04)

  • Add a scripts/generate script which generates a python package -> debian binary mapping suitable for adding to van/pydeb/py_to_bin.txt.

  • Append the output of the generate script to van/pydeb/py_to_bin.txt.

  • Expose _default functions for package conversions so that generate can check it’s results and weed out extra packages that match the default conversions.

  • Make python-pkg-resources the default translation for setuptools:

  • Add the concept of options to the list of dependencies.

  • Create a “reduced” option that causes warnings to be printed when a reduced dependncy is used.

  • Implement a –override-bdep option which can be used to override python to binary package dependencies.

1.2.1 (2009-06-15)

  • Add mapping for ZConfig and RestrictedPython.

  • Change default Debian binary to python package name conversion. The original package name will be used if there is no python-prefix. This works with packages such as buildbot which do not include the python-. The previous version errored in this case, so we’re backwards compatible :)

1.2.0 (2009-05-29)

  • Improve README.txt. Thanks to Fabio Tranchitella for a better looking way of calling van-pydeb in the rules file.

  • Expose version and package name conversion functions via the command line interface. e.g. This command will print out the debian binary package name:

    $ van-pydeb py_to_bin foo

1.1.0 (2009-05-26)

  • Obligatory “How could I have done that” release smoothing out documentation bugs and making the command line options more complete.

1.0.0 (2009-05-26)

  • Initial Release.
