[gentoo-devhelp] PYTHON_DEPEND syntax

[gentoo-devhelp] PYTHON_DEPEND syntax

[Nikos Chantziaras]

I'm not sure I understand PYTHON_DEPEND. If I have a package that works 
with Python 2.6 and newer (like 2.7), but is incompatible with 3.x 
versions, how do I state that?  What I want is:

  >= 2.6 && < 3

I think that the correct syntax for this would be
PYTHON_DEPEND="2:2.6" if I'm reading the docs for
_python_parse_PYTHON_DEPEND() correctly.

Are you installing a python module or just something which uses
python? For a module, you will need to define PYTHON_RESTRICT_ABIS to
"2.[1-5] 3" after setting SUPPORT_PYTHON_ABIS=1 and doing all the
magic to support multiple ABIs (which might be none if you're using
distutils).

There is useful information at
http://www.gentoo.org/proj/en/Python/developersguide.xml too.

Thanks.  I tend to RTFM less these days directly on Gentoo.org since 
most of the time the docs are outdated and don't apply to what I'm 
looking for.  But in this case, they helped :-)

Hm, it's good idea to report such issue to bugs.gentoo.org. This is the
only way to notify developers to update docs ;)
