Firepad sync after onClick vs onKeyUp

[Maarten]

Is it possible for Firepad to only sync when a button (like save) is clicked, as opposed to syncing after every keystroke?

Hrm...  That's not really what it's designed for.  Do you still want collaborative editing (to see other people's edits)?  Or are you just looking for a one-way "save to database" behavior?  If the latter, you might be better served just using the normal Firebase client to save the entire editor when "save" is clicked or something.

Oh yes I am looking for collaborative editing alright. Just not that superduper realtime.

I am building a text editor that can be used offline as well. So user X can create a document and take it offline to edit if further. In the meanwhile it may have been edited by user Y. When user X gets online again, both docs should be merged to represent latest revision.

When do you want to see other users' edits?  When you press "save" (so it'll sync in both directions at that time)?  Or before that?

I guess I want to see edits immediately once they're available. Typically that would be when a user presses save, yes.

So you want to *receive* updates continuously (whenever another user presses "save") but only *send* your updates when you press "save"?

That's not currently possible, but could be implemented I guess.  You'd basically need to modify the state machine in  client.js.  So the default state behaves more like AwaitingWithBuffer (which queues up a buffer of operations) rather than Synchronized (which sends new operations immediately) and then plumb in a mechanism to flush the buffer.  It'll be a bit tricky and you'll have to deal with all the state transitions (such as the user pressing save and then pressing it again before the first save completes).

If you decide to give it a go and have questions, let me know.
