DH_PYTHON2() DH_PYTHON2() NAME
dh_python2 - calculates Python dependencies, adds maintainer scripts to byte compile files, etc. SYNOPSIS
dh_python2 -p PACKAGE [-V [X.Y][-][A.B]] DIR_OR_FILE [-X REGEXPR] DESCRIPTION
QUICK GUIDE FOR MAINTAINERS o if necessary, describe supported Python versions via X-Python-Version field in debian/control, o build-depend on python or python-all or python-all-dev (>= 2.6.6-3~), o build module/application using its standard build system, remember to build extensions for all supported Python versions (loop over pyversions -vr), o install files to the standard locations, add --install-layout=deb to setup.py's install command if your package is using distutils, o add python2 to dh's --with option, or: o include /usr/share/cdbs/1/class/python-distutils.mk in debian/rules and depend on cdbs (>= 0.4.90), or: o call dh_python2 in the binary-* target, o add ${python:Depends} to Depends, NOTES In order to support more than one Python version in the same binary package, dh_python2 (unlike dh_pycentral and dh_pysupport) creates sym- links to all supported Python versions at build time. It means binNMU (or sourceful upload in case of architecture independent packages) is required once a list of supported Python version is changed. It's faster and more robust than its competitors, though. dependencies dh_python2 tries to translate Python dependencies from requires.txt file to Debian dependencies, use debian/pydist-overrides or --no-guess- ing-deps option to override it. If you want dh_python2 to generate more strict dependencies (f.e. to avoid ABI problems) create debian/python-foo.pydist file. See /usr/share/doc/python-doc/README.PyDist (provided by python-doc package) for more information. namespace feature dh_python2 parses Egg's namespace_packages.txt files (in addition to --namespace command line argument(s)) and drops empty __init__.py files from binary package. pycompile will regenerates them at install time and pyclean will remove them at uninstall time (if they're no longer used in installed packages). It's still a good idea to provide __init__.py file in one of binary packages (even if all other pack- ages use this feature). private dirs /usr/share/foo, /usr/share/games/foo, /usr/lib/foo and /usr/lib/games/foo private directories are scanned for Python files by default (where foo is binary package name). If your package is shipping Python files in some other directory, add another dh_python2 call in debian/rules with directory name as an argument - you can use different set of options in this call. If you need to change options (f.e. a list of supported Python versions) for a private directory that is checked by default, invoke dh_python2 with --skip-private option and add another call with a path to this directory and new options. pyinstall files Files listed in debian/pkg.pyinstall file will be installed as public modules for all requested Python versions (dh_install doesn't know about python's site- vs. dist-packages issue). Syntax: "path/to/file [VERSION_RANGE] [NAMESPACE]". debian directory is automatically removed from the path, so you can place your files in debian/ directory and install them from this location (if you want to install them in "debian" namespace, set NAMESPACE to debian). If NAMESPACE is set, all listed files will be installed in .../dist-packages/NAMESPACE/ directory. Examples: o foo.py (installs .../dist-packages/foo.py for all supported Python versions) o foo/bar.py 2.6- (installs .../dist-packages/foo/bar.py for versions >= 2.6) o foo/bar.py spam (installs .../dist-packages/spam/bar.py) o debian/*.py spam.egg 2.5 (installs .../python2.5/site-packages/spam/egg/*.py files) pyremove files If you want to remove some files installed by build system (from all supported Python versions or only from a subset of these versions), add them to debian/pkg.pyremove file. Examples: o *.pth (removes .pth files from .../dist-packages/) o bar/baz.py 2.5 (removes .../python2.5/site-packages/bar/baz.py) OPTIONS
--version show program's version number and exit -h, --help show help message and exit --no-guessing-versions disable guessing other supported Python versions --no-guessing-deps disable guessing dependencies --no-dbg-cleaning do not remove any files from debug packages --skip-private don't check private directories -v, --verbose turn verbose mode on -i, --indep act on architecture independent packages -a, --arch act on architecture dependent packages -q, --quiet be quiet -p PACKAGE, --package=PACKAGE act on the package named PACKAGE -N NO_PACKAGE, --no-package=NO_PACKAGE do not act on the specified package -V VRANGE specify list of supported Python versions. See pycompile(1) for examples -X REGEXPR, --exclude=REGEXPR exclude items that match given REGEXPR. You may use this option multiple times to build up a list of things to exclude. --compile-all compile all files from given private directory in postinst/rtupdate not just the ones provided by the package (i.e. do not pass the --package parameter to pycompile/pyclean) --depends=DEPENDS translate given requirements into Debian dependencies and add them to ${python:Depends}. Use it for missing items in requires.txt --recommends=RECOMMENDS translate given requirements into Debian dependencies and add them to ${python:Recommends} --suggests=SUGGESTS translate given requirements into Debian dependencies and add them to ${python:Suggests} --namespace use this option (multiple time if necessary) if namespace_packages.txt is not complete --ignore-namespace ignore Egg's namespace declaration and --namespace option. This option will disable removing (and recreating at install time) empty __init__.py files. Removing namespace_packages.txt from egg-info directory has the same effect. --clean-pycentral generate maintainer script that will remove byte code generated by python-central helper --ignore-shebangs do not translate shebangs into Debian dependencies SEE ALSO
