Importmagic fixes Python imports automatically. It has a few dependencies

(sexpdata, epc) not yet packaged in Guix, and a corresponding Emacs mode.

Ryan Prior (4):

gnu: Add python-importmagic.

gnu: Add python-sexpdata.

gnu: Add python-epc.

gnu: Add emacs-importmagic.

Thanks! This patch did not apply for me somehow, can you rebase on the

current master branch?

I applied the other three, all LGTM.

Looks like a conflict in the copyright line. (Something something lawyers.) New patch attached!

OOC, are you sure Python packages need to be propagated in this case?

Hi Nicholas! I tried it with the python packages in "inputs" and impotmagic.el complained about not being able to find them. I'm going to be helping with maintenance of importmagic.el so maybe that's something I can fix on the package side?

At present this seems to work better. I don't know yet what the difference is between inputs and propagated-inputs when it comes to Python packages so maybe somebody else might have a better answer.

The difference is that propagated-inputs will be installed to the

profile when you 'guix install emacs-importmagic'.

Propagating these will only work if the user already has 'python' in the

profile, which sets up PYTHONPATH.

For regular executables, we solve this by "wrapping" the executable with

PYTHONPATH to avoid the need for propagation.

Ideally we'd patch importmagic.el so that it automatically sets

PYTHONPATH referring to these two packages (prepending to any existing

PYTHONPATH). I think python-shell-interpreter also should use the

absolute file name of the "python" executable so it does not have to be

installed separately.

Do you think that can work?

Thanks for chiming in Nicolas, I had completely missed those propagated

Python packages. :-)

I'm going to look into it. Prepending the PYTHONPATH and manipulating the python-shell-interpreter doesn't sound like it should be tricky.

Do you by chance know of other Emacs packages in Guix which do this kind of patching so I can look at an example? I'll do some grepping around and see what I can find, or just try something and iterate from there.
