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

Hey thanks Ben - this still doesn’t work for me… good idea to try on the Pharo repo itself.

I have a fork of it, which I catch up periodically - so I tried a similar suggestion to you - went into my directory (underneath the src folder) and typed:

log --diff-filter=D --summary --graph --pretty='format:%cd | %h | %H | %cn%n-> %s%n’

This gave me:

Tue Jun 19 19:28:37 2018 +0200 | 13e81343e | 13e81343e8a23a8d6ca43f1c77b804b8134fc986 | CyrilFerlicot
-> Remove now useless logs

 delete mode 100755 bootstrap/scripts/printFolderContent.sh

Mon Jun 18 16:50:19 2018 +0200 | 0433d908d | 0433d908de2987fa0069a47dee1f0794ccbb52c2 | GitHub
-> Revert "22161-Add-more-log-to-bootstrap"

 delete mode 100755 bootstrap/scripts/printFolderContent.sh

Thu Jun 14 11:41:16 2018 +0200 | b4a285a61 | b4a285a61d3eb0cc1e642b2fcc242dac7092617f | Marcus Denker
-> fix the last sender of #asIcon https://pharo.fogbugz.com/f/cases/22139/fix-the-last-sender-of-asIcon

 delete mode 100644 src/Polymorph-Widgets-Rules/IconShortcutRule.class.st

So then I tried to recover that last one (again at root underneath the src directory)

git checkout b4a285a61 src/Polymorph-Widgets-Rules/IconShortcutRule.class.st
error: pathspec 'src/Polymorph-Widgets-Rules/IconShortcutRule.class.st' did not match any file(s) known to git.

And I still get that dreaded pathspec error. This is on OSX (not windows) - so I’m struggling to understand what I could be doing wrong. It must be something obvious - but damned if I can see how I’m doing anything different to you. And it wouldn’t make sense that git is broken on OSX?
