Inline::Python, pyperl, etc.

[Eli Stevens (WG.c)]

The group I work with is trying to be language agnostic between Python
and perl. We are trying to make it so that we are able to call our
various APIs from one language or the other without having to care* what
language the API was written in.

I've been looking into:

Inline:ython 0.22
http://search.cpan.org/~neilw/Inline-Python-0.22/Python.pod

PyPerl 1.0.1
http://wiki.python.org/moin/PyPerl

The interest in these projects seems to have died off about 2001,
however. That, or they simply haven't needed to be updated for the last
few Python versions.

I've bumped into some snags with pyperl (can't import perl2.so? But
it's right there in site-packages/ !), and I'm wondering if it's bitrot
or a config error on my end.

Similarly, with Inline:ython I end up getting strings passed into my
python code when I expect integers (I posted about this on
(e-mail address removed), but things seem pretty dead over there).

Is anyone actually using any of this stuff?

Thanks for any feedback,
Eli

If the .so file is as old as you described, it's probably linked to an
old version of python. Try recompiling it.

The perl2.so is not old though; it was built as part of the pyperl
install I just did. Since the file ended up at (without needing any
prompting from me):

/usr/local/lib/python2.4/site-packages

I'm fairly confident that it's linked against python 2.4. But still:

But again, I'm not so much interested in fixing this specific problem;
I'm wanting to know if anyone is actually using Inline:ython or PyPerl
in any real sense. If they are dead projects that will have to factor
into our decision to use them or something else.

Thanks for the input,
Eli

I made some patches to pyperl and the unit testing suite some months
ago. At least basic functionality is working again. Have a look at the
zope-perl mailing list.
I don't know if I announced a single source tar.gz on this mailing list
but if you have still some interest in this I can mail you the package.
