I would like to announce the initial public release of stdeb, which may
be found at http://stdeb.python-hosting.com/ . I send this email to the
debian-python list with a little hesitation because I know this utility
does not (yet) produce Debian source packages that adhere to Python
Python policy. However, I hope that people here will appreciate the
usefulness of such a tool and might help make it produce such packages.
The rest of this email is copied directly from the project 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/
News
----
2006-06-19: Version 0.1 Released. See the `download page`_.
Invocation
----------
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).

Background
----------
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`_.
.. _easydeb: http://easy-deb.sourceforge.net/
.. _Logilab's DevTools: http://www.logilab.org/projects/devtools
Prerequisites
-------------
* Python_ 2.3 or greater
* setuptools_
* subprocess.py_ (included with Python 2.4, backwards compatible with
Python 2.3)
.. _Python: http://www.python.org/
.. _subprocess.py:
http://svn.python.org/view/python/trunk/Lib/subprocess.py?rev=46651&view=log
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
TODO
----
* 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.
