Johan, I made a hierarchical state machine framework in VA Smalltalk, and use it to this day in an application that has several state machines comprising hundreds of states. Unfortunately, it's not open source, and I don't own the code, so I can't share it. It has #assumeState and #relinquishState methods that get sent when a state is entered or left, and #assumeSuperstate and #relinquishSuperstate methods that get sent as a state transition crosses the contours of superstates. If an open source equivalent exists, I'd be interested in checking it out. Bob On Tue, Apr 8, 2014 at 3:47 PM, Johan Fabry <jfabry@dcc.uchile.cl> wrote:
Hi all,
I was wondering if there is an implementation of a hierarchical state machines (with input and output actions) available somewhere for Pharo. Any ideas?
Thanks in advance!
