I wrote about undo before and I pushed it farther. What about an undo/redo system? I extended the v.01 of the undo and I now handle undo and redo in the same object.
Annoucing redo in jskata.undo
I made a new version of jskata.undo still hosted on GitHub. If you look closer, it is now part of a library called jskata that is not officially announced. My next post will talk about it in details.
How does it work?
Execute an action that you can undo/redo
Doing something requires calling execute with 2 functions as parameters : the do and the undo.
Undo and redo the last action
Events and properties
For the moment, jskata.undo has just one event : onChange.
There are 2 properties : canUndo() and canRedo().
