OK I see what you did there.

I think this is a little tidier than my solution of printing a message and re-raising the exception.

My one comment is that it took me a full minute to find the filename in the traceback in your example.

My crude approach puts the filename just before the exception and I found it much more readable.

(I think I have code-blindness - seeing lots of similar text of a screen I can never focus in on the bit I need! - so this may just be a personal issue)

I wouldn't say that re-constructing the validation error was super tidy. So I have a slight preference for catch - print - re-raise.

Yeah I think this is just as good and less code:

+ ibek runtime generate /epics/ioc/config/ioc.yaml /epics/ibek-defs/ADCore.ibek.support.yaml /epics/ibek-defs/ADSimDetector.ibek.support.yaml /epics/ibek-defs/asyn.ibek.support.yaml /epics/ibek-defs/autosave.ibek.support.yaml /epics/ibek-defs/epics.ibek.support.yaml /epics/ibek-defs/iocStats.ibek.support.yaml
