When I run a treatment inside QGIS with Processing toolbox (native algorithms) I get a progression bar :
Is there a way to use this percentage inside a standalone PyQGIS script? I searched in the description of processing.run() but it seems nothing is linking to this progression bar.
Yes - processing.run accepts a "feedback" argument, which must be an instance of a QgsProcessingFeedback subclass.
If you construct your own feedback object to pass to this function, you can connect to the progressChanged signal and handle progress reports:
def progress_changed(progress):
print(progress)
f = QgsProcessingFeedback()
f.progressChanged.connect(progress_changed)
processing.run(...., feedback=f)
