I've run guix lint and should be fine. I'm having a bit of a hard time with formatting so I will probaby have to recreate the perfect setup from the documentation.
Packaging python-rtmidi in an effort to bring a complete DMX workflow to guix.

Sorry; this is a fixed patch. Still trying to use pytest, but haven't found a nice way to add the add-installed-pythonpath logic, which is not present in the meson-build system

Hi, since this is a Python library, do we want to make the Python inputs propagated?

Were you able to test in a shell that the following works fine when run from a script or repl?

If not, can you test that and report back on the results. I'll give it a try after.

Or, how have you gone about testing that this package works in a Guix environment with all the system audio requirements?


```python
import time
import rtmidi

midiout = rtmidi.MidiOut()
available_ports = midiout.get_ports()

if available_ports:
midiout.open_port(0)
else:
midiout.open_virtual_port("My virtual output")

with midiout:
note_on = [0x90, 60, 112] # channel 1, middle C, velocity 112
note_off = [0x80, 60, 0]
midiout.send_message(note_on)
time.sleep(0.5)
midiout.send_message(note_off)
time.sleep(0.1)

del midiout
```

all best,

jgart

Hi,

I will look into the propagated inputs question. Indeed looking at the
documentation python does not belong there.

Your example works at a foreign distro using guix (Fedora) with jack, which
is where I've tested the declaration. On Guix system it seems to work when
using the PipeWire Home Service, but I can't get it to work with the
standalone jack2 just yet. So that's something I've got to look into as
well.

It wasn't my intention to submit a poorly working patch, sorry. Somewhere
next week probably I will compose a new patch revision.

Hi,

I've installed guix-system and did some further testing:

The package seems to work just fine when properly installing jack2,
pipewire (pw-jack) or jack on guix-system (and Fedora). It's possible to
put jack (v1) in the propagated inputs, but that's not that elegant I
suppose. Furthermore all the audio packages I could find in guix include
jack in the same way, at build time and not as a propagated input.

I cannot test this with actual midi hardware, only with the
midiout.open_virtual_port method. But for my use case (using the OLA
suite), the library works fine, even when using real DMX controller
hardware.

So after testing and configuring my system properly, I have found no reason
for a revised patch. If you or someone else wants to take a look at this
patch, please do.

Thanks.

Hi,

Could someone have a look at this? It builds and works. Feedback is much
appreciated.
