That's actually a very good idea. As I said, now I am just trying to start with this, and integration is scripts seems an easy first step, but eventually, I would like to have support for variables (or even better, full expressions) in the textboxes of the algorithm dialog > > I also think that it's often implicitly clear from the context an > expression appears in, which layer should be the source of the variables. > If an algorithm uses several layers, the algorithm context contains those layers, and it should be possible to use variables from all of them to set the other parameters of the algorithm. > What are the use cases you have in mind? No particular case for now. I am just trying to make Processing more useful for automating all sort of operations within QGIS :-) _______________________________________________ Qgis-developer mailing list [email protected] List info: http://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: http://lists.osgeo.org/mailman/listinfo/qgis-developer
