Hi all,
I have written a tool [1] in python and packaged it in AUR [2], now I
have the following problem:
1) The tool is written compatible with python 2.7 and 3.x, so I'd like
to depends on something like (python=2.7), but the package python2
does not provides python=$pkgver. So what should the package depend
on? (is there an or-like operator in depends=?)
You can't specify an OR dependency relation in a PKGBUILD, so it's
up to you whether it'll depend on 'python' or 'python2'.
2) How about the shebang line then? Now it is /usr/bin/env python
but if the user only installed python2 this won't work correctly in
the default case.
/usr/bin/env python3 if you decide on Python 3; /usr/bin/env
python2 otherwise.
It may be a good idea to keep /usr/bin/env python on Github and
change it using sed(1) in the PKGBUILD. This way the upstream script
will support both major Python versions, while the AUR package can be
tailored for Arch.
I've been keeping a watchful eye on recent rebuilds of python
packages, but still confused about the above situation, thanks for any
ideas :)
