== Introduction ==

The usual way of developing Maemo applications is using or Scratchbox or [[MADDE]], which are quite heavy for Python development. An alternative is using [http://github.com/astraw/stdeb stdeb], a set of extensions to distutils that allows generating debian packages, both binary and source, that can be installed on the device or sent to the [[extras-devel]] repository.

This tutorial will show how to integrate it into your project, building the packages and uploading it to extras-devel.

== Prerequisites ==

This tutorial is aimed at Debian-based systems, as some stdeb commands requires the dpkg tools installed.

Also, you should get the [http://github.com/astraw/stdeb git] version of stdeb to use the debianize command, as it is a new addition and not yet available in the repositories. Run the following commands to install it:

# Clone the git repository
 git clone http://github.com/astraw/stdeb.git

# Enter source package
 cd stdeb

# Build .deb (making use of stdeb package directory in sys.path).
 python setup.py --command-packages=stdeb.command bdist_deb

# Install it
 sudo dpkg -i deb_dist/python-stdeb_0.5.1+git-1_all.deb

As only python2.5 is supported in pymaemo, it should be installed if you want to create binary packages. On Ubuntu Lucid (10.04), you can install it from [https://launchpad.net/~fkrull/+archive/deadsnakes this ppa], following the instructions [http://www.codigomanso.com/en/2010/05/google-app-engine-en--10-4-lucid-lynx/ here].

== Preparing the package ==

As stdeb extends distutils, it is necessary that you have a working setup.py script. For our example application, which consists of a [http://pymaemo.garage.maemo.org/stdeb_example/myscript-app/myscript single script] named "myscript" and support files like [http://pymaemo.garage.maemo.org/stdeb_example/myscript-app/myscript.desktop .desktop]<ref name="desktop">[[Desktop file format]]</ref> and an [http://pymaemo.garage.maemo.org/stdeb_example/myscript-app/myscript.png icon]<ref name="icon">[[Packaging#Displaying an icon in the Application Manager next to your package]]</ref>, the [http://pymaemo.garage.maemo.org/stdeb_example/myscript-app/setup.py setup.py] will look like this:
<source lang="python">
from distutils.core import setup

setup(
    name='myscript',
    version='0.1',
    author='Lauro Moura',
    author_email='lauro.neto@donotspamme.com',
    scripts=['myscript'],
    data_files=[('share/applications/hildon', ['myscript.desktop']),
                ('share/pixmaps', ['myscript.png'])],
)
</source>
A file named [http://pymaemo.garage.maemo.org/stdeb_example/myscript-app/stdeb.cfg stdeb.cfg] in the same directory as setup.py is required, with stdeb Maemo-specific options. A detailed list of options can be found in the [http://github.com/astraw/stdeb stdeb website].

[DEFAULT]
 XS-Python-Version: 2.5 # Only version currently supported by pymaemo.
 Package:myscript # Binary package name. stdeb adds the prefix "python-" by default
 Section: user/development # Section should start with user/ to appear in the menu.
 Depends: python-gtk2 # add extra dependencies here

Make sure to use [[Maemo_packaging#Sections|an allowed section]] - otherwise the autobuilder will give a warning.

== Building the packages ==

The basic command is

python setup.py --command-packages=stdeb.command bdist_deb

It'll create a folder called deb_dist with the source and binary packages. Alternatively, the "sdist_dsc" command will create only the source package.

After generating, you can copy the package to your device and install it (requires an [[SSH]] server):

$ scp myscript_0.1-1_all.deb root@<n900 ip>:/root
 $ ssh root@<n900 ip>
 # dpkg -i myscript_0.1-1_all.deb

== Building a basic debian directory ==

Another useful command is ''debianize''. It will read the configuration file and write a directory named debian in the same directory. This can be used for manually creating the packages using dpkg tools directly.

Note: sdist_dsc and bdist_deb do '''not''' use this directory, generating a new one in the source dir under deb_dist/.

== Uploading to extras ==

To upload to extras, use the debianize command and then call dpkg-buildpackage:

$ dpkg-buildpackage -rfakeroot -uc -us -S

This command will create the .dsc, .tar.gz and .changes files that can be used to [[uploading to Extras-devel|upload the application to extras-devel]]

== Future work ==

Support for non-Debian systems.

-If you're using a distro not based on Debian, you can still create source packages for uploading to extras-devel, but won't be able to create binary packages (.deb).
-For doing this, you will need the sdist_deb module available [http://gitorious.org/pymaemo/sboxless here]; just clone it in some directory and point the PYTHONPATH environment variable there.
-Now create a file called sboxless.cfg, which will contain additional information for generating the package. For now, you can add additional runtime dependencies for your package. If you want to add python-twitter as dependency, just write
- [control]
- depends=python-twitter
-The file is mandatory, so if you don't want to add any dependency, just leave the field empty ('depends=').
-Now, run the sdist_deb command:
