Usage

//undo undo the latest worldedit command
//redo redo what was just undone
//show_journal view what can be undone and redone
With the more_chatcommands mod, other player's changes can be undone with /run_as <playername> //undo, where <playername> is the other player's name.

Undoing reverts changes of nodes (name, param1 and param2) and metadata. Node timers are not yet supported. The undo functionality should help against accidents; however, it should not be considered reliable since there is no guarantee that undoing always is possible or works correctly.

The changes of nodes after invoking a command such as /set are compressed to improve memory usage.

TODO

Allow undoing changes which happened before other changes (considered unsafe) e.g. //undo ~1 to undo the change before the latest one
Add code for more of the WorldEdit chat commands (see the lists above)
Add a verbose option to the //show_journal output to show detailed information such as the UTC time when the changes happened and the required memory to store them
