Wiki: Diff: MultiuserSyntaxHighlightTracking

  

 Another implementation strategy might be a sparse array for the buffer's characters, updated to show who edited which character last. This overlay would contain tokens for each editor of each character position. Highlighting would simply be making the characters the right color. While this may not track all the richness of editing history, it may simplify storage and implementation, keeping only the history information that will actually be used for display. 

  

 Once the method for tracking edits is understood, configuration to give a color to each of several connected clients/human editors/users should be configurable. Highlight commands can be used. Any data entered remotely will highlight until the end of the editing session. Perhaps an additional user interface and some kind of legend (perhaps using another buffer) could be provided to associate colors with actual users.
