QUICK GUIDE FOR MAINTAINERS

if necessary, describe supported Python 3 versions via X-Python3-Version field in debian/control,

build-depend on python3 or python3-all or python3-all-dev,

build module/application using its standard build system, remember to build extensions for all supported Python 3 versions (loop over py3versions -vr),

install files to the standard locations, add --install-layout=deb to setup.py's install command if your package is using distutils,

add python3 to dh's --with option, or:

include /usr/share/cdbs/1/class/python-distutils.mk in debian/rules and depend on cdbs (>= 0.4.90), or:

call dh_python3 in the binary-* target,

add ${python3:Depends} to Depends

NOTES
dependencies

dh_python3 tries to translate Python dependencies from requires.txt file to Debian dependencies. Use debian/py3dist-overrides or --no-guessing-deps option to override it if the guess is incorrect. If you want dh_python3 to generate more strict dependencies (f.e. to avoid ABI problems) create debian/python3-foo.pydist file. See /usr/share/doc/python3-doc/README.PyDist (provided by python3-doc package) for more information. If the pydist file contains PEP386 flag or set of (uscan like) rules, dh_python3 will make the depedency versioned (version requirements are ignored by default).

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_python3 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 3 versions) for a private directory that is checked by default, invoke dh_python3 with --skip-private option and add another call with a path to this directory and new options.

debug packages
In binary packages which name ends with -dbg, all files in /usr/lib/python3/dist-packages/ directory that have extensions different than so or h are removed by default. Use --no-dbg-cleaning option to disable this feature.

overriding supported / default Python versions
If you want to override system's list of supported Python versions or the default one (f.e. to build a package that includes symlinks for older version of Python or compile .py files only for given interpreter version), you can do that via DEBPYTHON3_SUPPORTED and/or DEBPYTHON3_DEFAULT env. variables.

Example: 3.2,3.3 limits the list of supported Python versions to Python 3.2 and Python 3.3.

options

--version

show program's version number and exit

-h, --help

show help message and exit

--no-guessing-deps

disable guessing dependencies

--no-dbg-cleaning

do not remove any files from debug packages

--no-shebang-rewrite

do not rewrite shebangs

--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 3 versions. See py3compile(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 py3compile/py3clean)

--depends=DEPENDS

translate given requirements into Debian dependencies and add them to ${python3:Depends}. Use it for missing items in requires.txt

--recommends=RECOMMENDS

translate given requirements into Debian dependencies and add them to ${python3:Recommends}

--suggests=SUGGESTS

translate given requirements into Debian dependencies and add them to ${python3:Suggests}

--shebang=COMMAND

use given command as shebang in scripts

--ignore-shebangs

do not translate shebangs into Debian dependencies
