Hi all, I'm trying a super simple script in Processing with the alg decorator syntax.
Basically I'm not doing anything, but a weird error is thrown when I try to append vector layer features to a list: NameError: free variable 'self' referenced before assignment in enclosing scope Traceback (most recent call last): File "/home/matteo/dev/build-QGIS-Desktop-Default/output/python/plugins/processing/gui/AlgorithmDialog.py", line 244, in on_complete self.feedback.pushInfo(self.tr('Execution completed in {0:0.2f} seconds').format(time.time() - start_time)) NameError: free variable 'self' referenced before assignment in enclosing scope And this the super small script: from qgis.processing import alg from qgis.core import QgsFeature, QgsFeatureSink @alg(name="myalg", label=alg.tr("My Algorithm"), group="examplescripts", group_label=alg.tr("Example Scripts")) @alg.input(type=alg.SOURCE, name="INPUT", label="Input layer") @alg.input(type=alg.SINK, name="OUTPUT", label="Output layer") def myalg(instance, parameters, context, feedback, inputs): """ Description goes here. (Don't delete this! Removing this comment will cause errors.) """ source = instance.parameterAsSource(parameters, "INPUT", context) (sink, dest_id) = instance.parameterAsSink( parameters, "OUTPUT", context, source.fields(), source.wkbType(), source.sourceCrs() ) l = [] features = source.getFeatures() for current, feature in enumerate(features): l.append(feature) out_feature = QgsFeature(feature) sink.addFeature(out_feature, QgsFeatureSink.FastInsert) return {"OUTPUT": dest_id} Some ideas?
