Though the python client doesn't support the 'shortcut' form, you can still specify it as a value for 'x-apache-selector' in the arguments for x-subscribe, e.g.

  ./drain "q;{create:always, link:{x-subscribe:{arguments:{'x-apache-selector':\"a = TRUE\"}}}}"

Comment 2 Zdenek Kraus 2014-04-23 05:18:05 UTC
Thank you, I will run tests with the 'x-apache-selector', but I really would like to have all clients use the same simple name 'selector', and IMO also others would like it too as well. We should keep it so unified as it could be.
