dh_pypy Man page



dh_pypy – calculates PyPy dependencies, adds maintainer scripts to byte
compile files, etc.


dh_pypy -p PACKAGE [-V [X.Y][-][A.B]] DIR [-X REGEXPR]


· build-depend on pypy and dh-python,

· add ${pypy:Depends} to Depends

· build module/application using its standard build system,

· install files to the standard locations,

· add pypy to dh’s –with option, or:

· call dh_pypy in the binary-* target,

dh_pypy tries to translate Python dependencies from the requires.txt
file to Debian dependencies. In many cases, this works without any
additional configuration because dh_pypy comes with a build-in mapping
of Python module names to Debian packages that is periodically regener‐
ated from the Debian archive. By default, the version information in
the Python dependencies is discarded. If you want dh_pypy to generate
more strict dependencies (e.g. to avoid ABI problems), or if the auto‐
matic mapping does not work correctly for your package, you have to
provide dh_pypy with additional rules for the translation of Python
module to Debian package dependencies.

For a package pypy-foo that depends on a package pypy-bar, there are
two files that may provide such rules:

1. If the pypy-foo source package ships with a debian/pypy-overrides
file, this file is used by dh_pypy during the build of pypy-foo.

2. If the pypy-bar source package ships with a debian/pypy-bar.pydist
file (and uses dh_pypy), this file will be included in the binary
package as /usr/share/dh-python/dist/pypy/pypy-bar. During the build
of pypy-foo, dh_pypy will then find and use the file.

Both files have the same format described in
/usr/share/doc/dh-python/README.PyDist. If all you want is to generate
versioned dependencies (and assuming that the pypy-bar package provides
the pybar Python module), in most cases it will be sufficient to put
the line pybar pypy-bar; PEP386 into either of the above files.

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_pypy 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 for a pri‐
vate directory that is checked by default, invoke dh_pypy with
–skip-private option and add another call with a path to this direc‐
tory and new options.

debug packages
In binary packages which name ends with -dbg, all files in
/usr/lib/pypy/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 PyPy versions
If you want to override system’s list of supported PyPy versions or the
default one (f.e. to build a package that includes symlinks for older
version of PyPy or compile .py files only for given interpreter ver‐
sion), you can do that via DEBPYPY_SUPPORTED and/or DEBPYPY_DEFAULT
env. variables.
