Proposal: Adding unversioned aliases to python3 binaries

Proposal: Adding unversioned aliases to python3 binaries

[Hartmut Goebel]

Hi,

I'm stepping into problems packaging python modules again and again
since Python 3.4 is not available  as `python`. Same for pip, and other
binaries in the python-3 package.

I propose
a) for python 3: adding symlinks from the unversioned binary name (e.b.
python) to the versioned
   ones (e.g. python3.4).
b) for python 2: adding symlinks from version binary names to unversion
ones -- for symmetry.


I'd appreciate if somebody more skilled in guix could implement this
(soon :-), so I could continue packaging stuff required for testing the
django framework.


Here is a list of required aliases for python 3:

easy_install-3.4 -> easy_install
idle -> idle3.4
pip -> pip3.4
pydoc -> pydoc3.4
python -> python3.4
python-config -> python3.4-config

And here for python 2:

2to3-2.7 -> 2to3*
idle2 -> idle
idle2.7 -> idle
pydoc2 -> pydoc
pydoc2.7 -> pydoc

Can you look at the 'python-wrapper' package and see if it would solve
this problem for you?

"description: This package provides wrappers for the commands of Python
3.x such that they can be invoked under their usual name---e.g.,
`python' instead of `python3'."

Thanks for the pointer. I'll try it out and report. Will take few days
unfortunately.

This solves the problem only party: When adding "python-wrapped" as a
native-input to some module you need to explicitly *remove* it for
"package-with-python2", since there is no package "python2-wrapped".

So I change my proposal into:

Add python2-wrapper for symmetry with python-wrapper.

Comments?
