Tangentially related, I've been thinking about how it is somewhat difficult to describe state machines in regular textual code, and it would be nice to have a drag-and-drop visual interface for mapping out the states and transitions, then tie regular code to the transition events.

Is there anything like that out there? Or a good open source diagramming library that might lend itself to prototyping this?

You might be interested in XState[0] and its visualizer[1]. It is not drag and drop, but it does provide a nice visualization that can help debug state logic. I imagine it’s possible to extend it to support visual manipulation and code generation.

Project is JS/TS-specific, however.

Thanks for sharing!

It will be soon ;-)

QtCreator has a SCXML based visual editor for state charts https://doc.qt.io/qtcreator/creator-scxml.html

Thank you! This looks very much like it would fit my needs, and I love that the output is an XML file I can integrate with other tools.

Yakindu comes to mind as one (if you aren't allergic to eclipse :-) )
