Línea de trabajo

The blocking call is the subprocess.run invocation around line 205 of music21/converter/subConverters.py, which the issue proposes replacing with subprocess.Popen. Read how that converter's show path builds cmd and how other subconverters reach the same code, since the change affects every format shown through it. Done means score.show('xml') returns immediately while the existing non-blocking behaviour for other formats is unchanged, and the open question about side effects on other converters is answered in the thread.

Descripción

enhancement

Would be great if score.show('xml') wouldn't block the execution of a script until the MuseScore instance displaying the musicxml-file is closed down. Similar request as this:

https://stackoverflow.com/questions/64949701/stream-show-without-interrupting-code-in-music21-similar-to-matplotlib-pyploy

But subprocess.run is a blocking call, subprocress.Popen is the non-blocking call

Motivation
Improve usability in a scripting environment like PyCharm

Proposed implementation

I fixed it locally in subConverters.py, line 205:

        #subprocess.run(cmd, check=False, shell=shell)
        subprocess.Popen(cmd, shell=shell)

But don't know enough about the code structure to know if this will cause problems with other converters.

Intent

[X ] I plan on implementing this myself.
[ ] I am willing to pay to have this feature added.
[X ] I am starting a discussion with the hope that community members will volunteer their time to create this. I understand that individuals work on features of interest to them and that this feature may never be implemented.
