Support Eclipse Undo/Redo operations ------------------------------------ Key: FORGE-1341 URL: https://issues.jboss.org/browse/FORGE-1341 Project: Forge Issue Type: Feature Request Components: Brainstorming, UI - Eclipse Affects Versions: 2.0.0.Beta3 Reporter: George Gastaldi Fix For: 2.x Future {quote} <gastaldi> koentsje, is it possible to undo the operations done by a Forge addon using the Eclipse Undo feature (Edit -> Undo) ? <gastaldi> can we somehow make the current plugin aware of this? <koentsje> hm, i think that will be a very tough one <gastaldi> I am reading http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.do... to understand how undoable operations work in Eclipse <gastaldi> It would be nice if we could somehow store a Delta of the modifications an addon does <gastaldi> so it's possible to undo/redo operations <koentsje> i would need to revisit that mechanism, it's probably five years ago since i used it :) <gastaldi> can we somehow create savepoints in Eclipse ? <gastaldi> at least you used it, this is totally new for me :) <koentsje> yes it should be possible <gastaldi> so I was thinking that maybe we could create a snapshot of the current project state before executing an operation, execute the addon, create another snapshot and then compare both to have a delta <gastaldi> this in turn could be undo/redoable <gastaldi> this could aid us in implementing the Accept Merges feature too <gastaldi> duh <gastaldi> Accept Changes <gastaldi> however that is a different subject <koentsje> the resource delta stuff exists already in eclipse <gastaldi> this is interesting, so it should be possible as you said <gastaldi> this would motivate people to use Forge inside Eclipse <koentsje> hm, i thought we went through all the ide pain because people want to use it in their ide? :) <gastaldi> yeah, that's the spirit :) {quote}
