Hi Sebastijan, Excellent work !!!
I have something similar (a BPM engine) but developed with GemStone Smalltalk: Code: https://github.com/brunobuzzi/BpmFlow Documentation: https://bpmflow.gitbook.io/project/introduction It can be ported to Pharo, from the top of my head i see a couple of issues with the port: - GemStone/S special indexes collection must be changed for regular Pharo collections. - GsQuery should be implemented in Pharo (maybe already is i do not know) or remove GsQuery references and so regular collection queries (select:, collect: anySatisfy and so on) The project is totally open source.
