I've been on the fence about adding that auto-detection in my python
slackbuilds. Some people think that this should be an option set at
build
time to add python3 support by using a variable.
Eg.
if ["${PYTHON3SUPPORT:-no}" == "yes" ]; then
python3 setup.py install --root=$PKG
fi
I'm not opposed to that, but I'm also not sure how to handle packages
that
put files in /usr/bin directory (like python-pillow) for python2 and
python3 scripts. If python3 files are built after python2 files, then
everything in /usr/bin/* will have a shebang with #!/usr/bin/python3.
I'm
not sure that is a desired outcome.
It may be best to create a second python3 package for python-pillow and
possibly other python slackbuilds that support python3 to avoid file
conflicts.
Perhaps we could also avoid duplicating packages where such conflicts
are possible, by adding an "else" statement in order to build either
with Python OR Python3 support. For example:
if ["${PYTHON3SUPPORT:-no}" == "yes" ]; then
python3 setup.py install --root=$PKG
else
python setup.py install --root=$PKG
fi

I wonder if something like the following test could be added to
python-pillow.SlackBuild, in order to automatically add support for
Python3
if the latter is installed:
python setup.py install --root=$PKG
+ if $(python3 -c 'import sys' 2>/dev/null); then
+ python3 setup.py install --root=$PKG
+ fi
I've been using this test in my script for glances, after borrowing it
from Larry Hajali's script for psutil, and it seems to do its job
nicely.
The reason for my suggestion is that I'm preparing a new SlackBuild
that
will require both python3 and python-pillow. The software expects
pillow to
support Python 3, but it doesn't, unless the script is manually
edited. I
understand that Slackware-current, from which the python-pillow script
was
taken, doesn't include Python 3, however SBo does, so it would be nice
to
have it autodetected. :)

Philip
