I wrote a quick program in python to add a gtk GUI to a cli program. I was wondering how I can create an installer using distutils. Since it's just a GUI frontend for a command line app it only works in *nix anyway so I'm not worried about it being cross platform.

my main goal is to create a .deb package for debian/ubuntu users, but I don't understand make/configure files. I've primarily been a web developer up until now.

edit: Does anyone know of a project that uses distutils so I could see it in action and, you know, actually try building it?

Here are a few useful links

  • Ubuntu Python Packaging Guide

    This Guide is very helpful. I don't know how I missed it during my initial wave of gooling. It even walks you through packaging up an existing python application

  • The Ubuntu MOTU Project

    This is the official package maintaining project at ubuntu. Anyone can join, and there are lots of tutorials and info about creating packages, of all types, which include the above 'python packaging guide'.

  • "Python distutils to deb?" - Ars Technica Forum discussion

    According to this conversation, you can't just use distutils. It doesn't follow the debian packaging format (or something like that). I guess that's why you need dh_make as seen in the Ubuntu Packaging guide

  • "A bdist_deb command for distutils

    This one has some interesting discussion (it's also how I found the ubuntu guide) about concatenating a zip-file and a shell script to create some kind of universal executable (anything with python and bash that is). weird. Let me know if anyone finds more info on this practice because I've never heard of it.

See the distutils simple example. That's basically what it is like, except real install scripts usually contain a bit more information. I have not seen any that are fundamentally more complicated, though. In essence, you just give it a list of what needs to be installed. Sometimes you need to give it some mapping dicts since the source and installed trees might not be the same.

Here is a real-life (anonymized) example:

#!/usr/bin/python 

from distutils.core import setup 

setup (name = 'Initech Package 3', 
          description = "Services and libraries ABC, DEF", 
          author = "That Guy, Initech Ltd", 
          author_email = "that.guy@initech.com", 
          version = '1.0.5', 
          package_dir = {'Package3' : 'site-packages/Package3'}, 
          packages = ['Package3', 'Package3.Queries'], 
          data_files = [ 
                       ('/etc/Package3', ['etc/Package3/ExternalResources.conf']) 
          ])

apt-get install python-stdeb

Python to Debian source package conversion utility

This package provides some tools to produce Debian packages from Python packages via a new distutils command, sdist_dsc. Automatic defaults are provided for the Debian package, but many aspects of the resulting package can be customized via a configuration file.

  • pypi-install will query the Python Package Index (PyPI) for a package, download it, create a .deb from it, and then install the .deb.
  • py2dsc will convert a distutils-built source tarball into a Debian source package.

Most Python programs will use distutils. Django is a one - see http://code.djangoproject.com/svn/django/trunk/setup.py

You should also read the documentation, as it's very comprehensive and has some good examples.

I found the following tutorial to be very helpful. It's shorter than the distutils documentation and explains how to setup a typical project step by step.

distutils really isn't all that difficult once you get the hang of it. It's really just a matter of putting in some meta-information (program name, author, version, etc) and then selecting what files you want to include. For example, here's a sample distutils setup.py module from a decently complex python library:

Kamaelia setup.py

Note that this doesn't deal with any data files or or whatnot, so YMMV.

On another note, I agree that the distutils documentation is probably some of python's worst documentation. It is extremely inclusive in some areas, but neglects some really important information in others.
