updated undo command to only track when a command changes the tree #1087

Closed birdalicious closed 1 year ago

birdalicious commented 1 year ago

undo now only undo changing commands for example:

git commit (C1)
git commit (C2)
git log
git log
undo

will now revert the state of the tree back to C1 where as before each undo would correspond to a git log command first so you would need 3x undos.

This should have no affect on undos in levels as they override the sandbox behaviour and have their own logic for tracking if a command counts for golf (which seems to be the same condition only captured explicitly for each command)

👏 🥳🥳🥳🥳

Great idea and UX improvement! Thanks a ton for the pull request -- definitely agree this is much better than having to undo "past" commands that didn't change the git state.

Will push the site now
