DH_PYTHON3(1) DH_PYTHON3(1)
NAME
dh_python3 - calculates Python dependencies, adds maintainer scripts to
byte compile files, etc.
SYNOPSIS
dh_python3 -p PACKAGE [-V [X.Y][-][A.B]] DIR [-X REGEXPR]
DESCRIPTION
QUICK GUIDE FOR MAINTAINERS
o if necessary, describe supported Python 3 versions via
X-Python3-Version field in debian/control,
o build-depend on python3 or python3-all or python3-all-dev,
o build module/application using its standard build system, remember
to build extensions for all supported Python 3 versions (loop over
py3versions -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 python3 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_python3 in the binary-* target,
o 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/dh-python/README.PyDist 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 differ-
ent than so or h are removed by default. Use --no-dbg-cleaning option
to disable this feature.
pyinstall files
Files listed in debian/pkg.pyinstall file will be installed as public
modules (i.e. into .../dist-packages/ directory) for all requested
Python versions.
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 loca-
tion (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 3.3- installs .../dist-packages/foo/bar.py for ver-
sions >= 3.3
o foo/bar.py spam installs .../dist-packages/spam/bar.py
o debian/*.py spam.egg 3.2 installs .../python3.2/dist-pack-
ages/spam/egg/*.py files
pyremove files
If you want to remove some public modules (i.e. files in .../dist-pack-
ages/ directory) 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 3.2 removes .../python3.2/dist-packages/bar/baz.py
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-ext-rename do not add magic tags nor multiarch tuples to extension
file names
--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/rtup-
date 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}

translate requirements from given file(s) into Debian dependen-
cies and add them to ${python3:Depends}
--shebang=COMMAND
use given command as shebang in scripts
--ignore-shebangs
do not translate shebangs into Debian dependencies
