Ruby causes crash

[syburn]

I was using a mirror ruby plug-in and my SU had a bug splash. Not the first time with this plug-in.

Is it quite normal for crashes when using ruby stuff. Any official list of safe rudy apps out there?

I have experienced this quite a few times with this ruby. No other ruby that I use has caused a bugsplat that I can recall. I usually (and it is automatic now) hit save before using this script. Or if there is quite a bit of geometry to be mirrored I will do it the old fashioned way

Thanks for the explaining TIG.

It's an infrequent and usually non-repeatable bug in SUp that Mirror.rb seems to encounter now and again. Some set ups and systems seem more prone than others. I developed this version of Mirror and the BugSplat comes when you mirror collections of certain types of geometry that aren't grouped - can't see a common denominator AND I've never had one***. You can try grouping before mirroring and exploding afterwards and see it that helps. It seems to be something to do with the way/order that SUp processes grouped objects - Mirror.rb temporarily groups your selection, makes the copy and mirrors it and then if desired deletes the original - it's often this deletion can lead to these rare splats.

There is a recent discovered clash between the Demeter.rb script and Mirror.rb (and Grow.rb) because Demeter has an aider-plugin called blankslate.rb and that seems to rewrite a bit of the way SUp+Ruby processes groups. This causes a crash every mirror+delete-original so it's unlikely to be your cause since it's intermittent ? ***I HAVE experienced that !

Until someone in SUp+Ruby fixes the flaky interpreter and group manipulation coding then occasional splats might randomly occur. So save beforehand and try pre-grouping what you are about to mirror - please let me know if you get any joy...
