I would like to add a button to the file explorer that starts an external program on the server after pressing it. Optionally with a checkbox which file it should work on or - even better - a button in the online text editor.
I have never wriiten a Nextcloud app, although I wrote many different apps and programs. Maybe one can give me a hint, where to start. It should not be a full-featured GUI, it is just a compile on a source code. (https://lilypond.org/)
Basically this example fits, but I am not sure about the file locations, so the path were the script is run from. That’s why I’m looking for a possibility to get log output
