I might be wrong but...how do you use that in the command line? We
already use io_gdal for converting formats (a step we would like to
avoid...), but the call to an actual module that does analysis can
only be made (correct me if I'm wrong) with a shapefile as input (in
the case of vector layers).

can you, for instance, call an algorithm passing a geojson file as input?

Thanks!
