[Pharo-users] Iceberg - finding deleted classes, reverting versions?

Hi Guille - I have tried the repo browser with the new iceberg loaded in Pharo 6.1 and I couldn’t see how it helps me? (I will make a firm point of using 7 now as I think I’ve now got a reasonable grasp of how things should work).
From the threads below - how would I find the commit with my missing class - Sean has pointed me to a git query that helps with that (and presumablyq is something we can plug into iceberg - maybe I will even take a look).
Having identified the hash with the class I want - getting to it is awkward (there is no search - again pretty easy for us to plug in, but something to do)
Having got to my commit - how can I retrieve one class? Maybe this is something only in Pharo 7 with Calypso? All I can see are diffs - so I’d have to copy and paste 20 methods and a class def. doable, but painful. I’m hoping there is a way to get a shadow copy of the commit from the tonel file and then use it to restore classes and methods? As this sounds like a decent chunk of work, I’m guessing it’s not done yet?
As a fallback, Any thoughts on why git won’t let me checkout a file from that commit? Something about the pathspec (is it mangled in some way)? And if I could restore a tonel file - would iceberg then recognise it to bring it back in, or Would I need to use some filestream foo to do that (as this would at least be a viable workaround for now)?
