Closes #16

image

First pass of the feature only.

Summary of changes:

  • Set up ShareDB LocalPresence instance
  • Listen for changes in CodeMirror
  • Broadcast presence using ShareDB API
  • Display the remote presence
  • Tested multiple connections (had to pass the sort arg to Decoration.set to fix this)
  • Tested editing after receiving presence. Had to add a setTimeout before dispatching the change to fix this, so there are not synchronous nested CodeMirror updates. This feels like somewhat of a hack, but not sure a better way.
  • Tested that presence cursors are transformed correctly when editing
  • Tested that presence cursors work across newlines

Current limitations:

  • Everyone's cursor is yellow
  • Does not handle removing presence yet
  • Does not yet support range selections (only the start of the selection is displayed remotely, for now)

This looks great! Everything installs and runs perfectly. May change some styling but great for now!
