Hi,

You need to get a hold of the editor
context service which gives you the ability to get/setText() into the editor
from plugins (amongst other things like get/setSelection, etc).  
The editor context is provide as a parameter in several other services:
 orion.edit.contentAssist,   orion.edit.outliner,   orion.edit.validator,
 etc.   I am not sure which one would be the best one for you
to hook into.   Maybe we should provide the editor context in another
service that makes more sense for what you are trying to do.  It could
be provided in the "orion.edit.model" service for instance.

As for getting the file path, I believe
it is only exposed to the orion.edit.validator service today (see [1]).
 There are requests in bugzilla to exposed it in other services as
well (see [2]).  One option is to provide it  via the editor
context.

I cannot recall anyway to get the current
user. I am not sure this is something that should be exposed to plugins
for security reasons.  Why is it necessary?

Finally, I wonder if doing the synchronization
of the changes in a orion plugin is feasible.  It might be something
that has to run in the host page for performance reasons.

Please open bug reports for anything
you might and we will try to address them.  Having shared editing
support is a cool feature.

Forwarding this question from Flux project.
Silenio or Bogdan do you have any thoughts on this. Is there a way for
a plugin to post incoming changes back into the editor model?

Hi all, 

I'm trying to create an editor plugin for Orion that would allow live (collaborative)
editing of a file in Orion. For example if multiple people changing the
same file resource I'd like to see live changes in my editor. In other
words I'd like to see changes in my editor not after someone saves the
resource, but as someone types characters. Suppose i have a messaging server
which receives and broadcasts changes to all clients editing the same resource.
Looks like i can create a plugin for Orion editor to transmit changes to
the messaging server using "orion.edit.model" extension with
onModelChanging event.
How can I sync back changes from others coming from the messaging server
back to my Orion editor? Is this possible with a plugin?

Orion extension plugin that hooks to “orion.edit.model” onModelChanging
event only has info about the event ni the editor: text added, number of
chars added, number of lines added and same for chars removed. At best,
some extensions get editor context object that can give a reference to
the contents of the editor via a deferred. Is it possible to gather some
additional information not available within the event such as current user,
file opened in the editor (file path)? If it’s not available within the
ModelChanging event perhaps it might be extracted from somewhere else?

Thanks in advance. 

Cheers,
