Petri net executor example by thorstink · Pull Request #276 · AlexInLog/ReactivePlusPlus

thorstink · 2022-09-17T19:24:29Z

As promised, an, imho fun and simplified example of implementing Petri net execution using reactive streams.

Note that it could be a bit fancier by executing the transitions in a different context - that way new transitions would get queued while the active transition is still running. Once RPP has something similar to RxCpp's observe_on_event_loop it would also be straightforward to actually execute transitions parallel using Rx-patterns.

Let me know if you think this example adds value to your project and if there's something you'd like to see clarified/improved.

Yeah, looks cool! Thank you!
Could you address comments from CI to pass it? Then i would merge it

The ci output https://github.com/victimsnino/ReactivePlusPlus/actions/runs/3074503201/jobs/4967539918 and https://github.com/victimsnino/ReactivePlusPlus/actions/runs/3074503201/jobs/4967539973 does not give me a clue what to look at (or I am missing it). Do you see it? Thomas

I was unable to easily reproduce this, clang-14 (which is was I had available) didn't give me this error (with the same flags as in the ci-matrix).. However, I think this edit should fix it.
