undo is broken in libedit

[Chris Pavlina]

I'm not 100% sure what's going on here, but undo in libedit is...messed up. Sometimes pressing ctrl-Z does nothing, and other times it undoes multiple actions at once. I'd go in more detail if I could discern any real pattern to it... but just start doing things in libedit, ideally a whole bunch of them, and start hitting undo. ¯\_(ツ)_/¯

Chris-

Can we close this one?

[Maciej Suminski (orsonmmz)]

Could be a problem with screen refreshing? It would explain why Ctrl+Z seems to do nothing and after several trials and a screen refresh it instantly undoes a lot of things.

[Seth Hillbrand (sethh)]

I've been poking at this a bit and can't seem to trigger the behavior with moving, renaming, rotating, etc, which was why I asked if it could be closed. But if you are still seeing the behavior, is there a specific command/sequence that you can reproduce it with?

[Seth Hillbrand (sethh)]

@orsonmz or Chris, can you say how you trigger this bug? I can't replicate on linux or Mac.

[Chris Pavlina (pavlina-chris)]

libedit's been seriously overhauled so I doubt this is relevant anymore. I can't repro this either.
