I would like to announce the initial public release of stdeb, which may be found at http://stdeb.python-hosting.com/ . The rest of this email is copied directly from that web-page.
stdeb - Python to Debian source package conversion utility ==========================================================
stdeb_ ("setuptools debian") produces Debian source packages from Python packages via a new distutils command, ``sdist_dsc``, which produces a Debian source package of a Python package. Automatic defaults are provided for the Debian package, but many aspects of the resulting package can be customized via a configuration file.
.. _stdeb: http://stdeb.python-hosting.com/
2006-06-19: Version 0.1 Released. See the `download page`_.
All methods eventually result in a call to the ``sdist_dsc`` distutils command. You may prefer to do so directly::
python -c "import stdeb; execfile('setup.py')" sdist_dsc
Alternatively, two scripts are provided::
stdeb_run_setup [options] # calls "python setup.py sdist_dsc [options]"
py2dsc [options] mypackage-0.1.tar.gz # uses pre-built Python source package
In all cases, a Debian source package is produced from unmodified Python packages. The following files are produced:
* ``packagename_versionname.orig.tar.gz`` * ``packagename_versionname-debianversion.dsc`` * ``packagename_versionname-debianversion.diff.gz``
These can then be compiled into binary packages using the standard Debian machinery (e.g. dpkg-buildpackage).
Files are available at the `download page`_.

The subversion repository is available at https://svn.stdeb.python-hosting.com/trunk
For the average Python package, its source distribution (python_package.tar.gz created with ``python setup.py sdist``) contains nearly everything necessary to make a Debian source package. This near-equivalence encouraged me to write this little distutils extension, which executes the setup.py file to extract relevant information. This process is made significantly easier through the use of setuptools_.
.. _setuptools: http://peak.telecommunity.com/DevCenter/setuptools
setuptools is used because of the opportunities it provides, although many of these features are currently un(der)-utilized. For example, setuptools could make the job of "Debianizing" python console and gui scripts much easier.
I wrote this initially to Debianize several Python packages of my own, but I have the feeling it could be generally useful. It appears similar, at least in theory, to easydeb_ and `Logilab's Devtools`_.

* Python_ 2.3 or greater * setuptools_ * subprocess.py_ (included with Python 2.4, backwards compatible with Python 2.3)

Customizing the produced Debian source package ----------------------------------------------
stdeb will attempt to provide reasonable defaults, but these are only guesses.
To customize the Debian source package produced, you may write config files of the format understood by ConfigParser_. When building each package, stdeb looks for the existance of a ``stdeb.cfg`` file in the ``.egg-info`` directory. You may specify an additional config file with the command-line option --extra-cfg-file.
.. _ConfigParser: http://docs.python.org/lib/module-ConfigParser.html
Here's an example .cfg file which builds several packages::
[DEFAULT] Debian-Version: 0ads1
[setuptools] Source: python-setuptools
[numpy] Source: python-numpy Upstream-Version-Prefix: 0.9.8+ Build-Depends: python-dev, refblas3-dev, lapack3-dev Build-Conflicts: atlas3-base, atlas3-base-dev
[matplotlib] # matplotlib doesn't incorporate its SVN version number into sdist-built tarballs. # Therefore, if building the SVN version, substitute the version into the # "Upstream-Version-Suffix" variable and use py2dsc. # (For some reason, "debuild -sa" won't build matplotlib because tk.h isn't found.) Source: python-matplotlib Upstream-Version-Suffix: .dev2500 Build-Depends: python-dev, python-numpy, python-numarray, python-numeric, python-gtk2-dev, tk8.4-dev, libwxgtk2.4-dev Depends: python-gtk2, python-numpy, python-numeric, python-numarray Suggests: gs-gpl
[scipy] Source: python-scipy Upstream-Version-Prefix: 0.4.9+ Build-Depends: python-numpy Depends: python-numpy
.. _numpy: http://scipy.org/NumPy
Using stdeb on stdeb --------------------
There is a chicken-and-egg problem when trying to make a Debian package of stdeb with stdeb. Here's a recipe to avoid it::
# in the stdeb distribution directory (with setup.py) python setup.py sdist python setup.py build PYTHONPATH="build/lib" python stdeb/py2dsc.py dist/stdeb-VERSION.tar.gz
* Make output meet `Debian Python Policy`_ specifications or the `new python policy`_. This will include several things, including:
- the ability to make custom changelogs - the ability to patch upstream source - the ability to include project-supplied documentation (including license information) as a -doc package - the ability to include project-supplied examples, tests, and data as a separate package - much more not listed
* Support python-central_ and/or python-support.
* Create (better) documentation
* Log output using standard distutils mechanisms
* Allow distribution-specific configuration parameters (e.g. numpy-dapper)

Call for volunteers -------------------
I don't have a lot of time for this. This project stands a very real chance of being only a shadow of its potential self unless people step up and contribute. There are numerous ways in which people could help. In particular, I'd be interested in finding a co-maintainer or maintainer if the project generates any interest. Secondarily, I would appreciate advice from Debian developers or Ubuntu MOTUs about the arcane details of Python packaging.
