DH_PYCENTRAL(1) Debhelper DH_PYCENTRAL(1)
NAME
dh_pycentral - use the python-central framework to handle Python
modules and extensions
SYNOPSIS
dh_pycentral [debhelper options] [-n] [-Xitem] [-V version]
[module dirs ...]
DESCRIPTION
dh_pycentral is a debhelper program that will scan your package, detect
public Python modules and move them in /usr/share/pycentral so that
python-central can byte-compile those for all supported Python
versions. Extensions are kept into the original installation location.
Moving the files to the pycentral location can be disabled by setting
the environment varibale DH_PYCENTRAL to a string containing the string
nomove.
To shorten the time of unavailabilty of files during unpack and
configure, dh_pycentral does the symlinking in the preinst and does not
remove the symlinked files on upgrade. This can be disabled by setting
the environment varibale DH_PYCENTRAL to a string containing the string
noprepare. If the newer version of a package needs to remove the
symlinked files on upgrade, either the package needs to take care of
the removal by calling pycentrel pkgremove in the new preinst, or
leaving a file /var/lib/pycentral/.pkgremove and using
pycentral 0.6.7 or later for the old package version.
You must have filled the XS-Python-Version header to indicate the set
of python versions that are going to be supported. dh_pycentral expects
the XB-Python-Version for each binary package it is supposed to work
on.
dh_pycentral will also generate substitution variables: the
${python:Provides} variable will contain versioned provides of the
package (if the packages name starts with "python-"). A python-foo
package could provide "python2.3-foo" and "python2.4-foo" at the same
time. Python extensions have to provide those whereas its only option
for pure python modules.
The ${python:Versions} variable should be used to provide the required
XB-Python-Version field listing the python versions supported by the
package.
OPTIONS
module dirs
If your package installs python modules in non-standard
directories, you can make dh_pycentral check those directories by
passing their names on the command line. By default, it will check
/usr/lib/$PACKAGE, /usr/share/$PACKAGE, /usr/lib/games/$PACKAGE,
/usr/share/games/$PACKAGE and /usr/lib/python?.?/site-packages.
Note: only /usr/lib/python?.?/site-packages and the extra names on
the command line are searched for binary (.so) modules.
-V version
If the .py files your package ships are meant to be used by a
specific pythonX.Y version, you can use this option to specify the
desired version, such as 2.3. Do not use if you ship modules in
/usr/lib/site-python.
With the new policy, this option is mostly deprecated. Use the XS-
Python-Field to indicate that youre using a specific python
version.
-n, --noscripts
Do not modify postinst/postrm scripts.
-Xitem, --exclude=item
Exclude files that contain "item" anywhere in their filename from
being taken into account to generate the python dependency. You may
use this option multiple times to build up a list of things to
exclude.
