Possible move coloring after opening? [message #1037221]

The syntax coloring in an xtext editor is done in opening; is it possible to make the color refresh after opening the editor? This will make the open faster, since we are developing a dsl no less complicated than java, with the coloring depending on cross references to make the color the same as the referenced element, then resolving cross references and loading more resources.

I tried putting the color refresh only in the partOpened method in a part listener, but in effect the editor won't show until the color refresh is finished in the listener, which then is the same as the default work flow.

A lot thanks if someone could help!!

Hi,

the semantic highlighting is actually not done on opening but asychronosly afterwards.
the syntactic highlighting is done on opening.

Hi, thanks for replying
But in opening it does "installHighlightingHelper", which then calls "HighlightingReconciler" to do the semantic highlighting:

document.readOnly(new IUnitOfWork.Void<XtextResource>() {
public void process(XtextResource state) throws Exception{
modeChanged(state);
}
});
...........
}
Is it asynchronous? In effect, the editor doesn't show up until this is done...

Hi,
What I tried later is running the refresh in reconciler.install in another thread. The effect is perfect: the editor shows up with only syntax highlight, then comes the semantic highlighting in a few seconds. Is there any risk of doing this?
