commandCallbackHandler catches Throwable making unrecoverable Errors impossible about tkd HOT 5 CLOSED

I must have used Throwable here for a reason (it's been three years, lol) probably to indeed catch memory errors. IIRC if an error is caught here, the program will crash and show you a Tk dialog box with the problem. This is built-in behaviour in Tcl/Tk.

The program continues execution as normal after displaying an error box. Not being able to crash the application is, surprisingly, a nuisance. 😛

The issue being that I have an external exception handler which needs to run instead of Tk's if an error occurs. Having it always catch everything is a big problem in this case.

Have you got a small example I could look at please?

from tkd.

Sure, here. The program never crashes despite throwing an Error.
I think this could be okay if an option to rethrow on callback errors were available, though I don't know how exactly that would be implemented.

I've done a lot of testing of different solutions and I think just changing Throwable to Exception is the simplest fix. Tkd should just let the program crash on encountering an error in a command. Done in commit: 35e1d91

I've also created a new release for this too: https://github.com/nomad-software/tkd/releases/tag/v1.1.10
