Allows the following to define processing scripts without the need for implementing a custom class:
from qgis.processing import alg
@alg(name="test2", label="test 2", group="test", groupid="test") @alg.input(type=alg.STRING, name="IN1", label="In string") @alg.input(type=str, name="IN2", label="In string 1", optional=True) @alg.input(type=str, name="IN3", label="In string 2") @alg.input(type=alg.SINK, name="SINK", label="Sink it!") @alg.output(type=str, name="OUT", label="WAT") @alg.output(type=alg.MAPLAYER, name="OUT2", label="WAT") @alg.output(type=alg.VECTOR_LAYER, name="VECTOR_LAYER", label="WAT") def testalg(instance, parms, context, feedback, inputs): """ This is a test function that does stuff """ feedback.pushInfo("We got these inputs!!") feedback.pushInfo(inputs['IN1']) feedback.pushInfo(inputs['IN2']) feedback.pushInfo(inputs['IN3']) return { "OUT2": "wat" }
