> Can you give us more information about the "CC/AT engine"? It's my own development. Viewed at high abstraction it does the things in the same way I suppose Google Wave / Docs and Etherpad do it. The client sends the server the sequence number of its idea of the data tree alongside with a change command. When the server receives two changes in say the same paragraph for the same sequence timestamp, it transforms one change by the other. So when you inserted text at position column 5 but someone else inserted a letter at column 0, it knows that this translates to inserting your text in column 6 instead. Similar mechanics with removing text.
The client keeps its own Undo/Redo chain, when commands from the server arrives, it applies these as transformations to the chain, so you always undo/redo *YOUR* last changes, ignoring what others did. -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups "nodejs" group.
