When an error occurs, stacktraces are get printed in the same order as the stack unwinds. This is the opposite of Python’s behavior and makes it so I always need to scroll up to see what caused the error. Is there a way of reversing this order?

I don’t think it is possible to customize this at the moment at the user level. That said, the current printing mechanism is pretty good about reducing/compressing repeated information, eg at most BIG_STACKTRACE_SIZE (currently 50) stack frames are printed, so it should fit on most screens. You ma…

Yes, the recent improvements are indeed very nice! Unfortunately with lots of parametric types the signatures still get really, long really fast. I’m not necessarily looking for a solution for all cases, just a way of customizing it for my needs (doesn’t need to be anything user-level, apparently in…

First off thanks for your work (and the work of others) on cleaning up the traces. I can see how having a flag might make things confusing, that being said different languages already print differently so the confusion is really only avoid if you only program in 1 language! I ended up just adding a …

if we are taking a poll, I would have to vote for reversing the order also. This would be especially useful when things in PyPlot fail because you get a LOT of python related messages before getting to the Julia errors. Generally though the stack traces and error messages aren’t too difficult to d…

To voice the opposing point of view, I always found Python’s stacktraces to be very confusing. It’s a stack, so the most recent call should be on top of the stack, right?

Yes, but we also draw trees with their root at the top of the page :slight_smile:
