Hi!

I have an instance of "HighlightReconciler".
I use this:

HighlightingReconciler reconcilier = editor.getHighlightingHelper().getReconciler();
reconcilier.addPosition(correspondingTag.getOffset(), correspondingTag.getLength(),	WMLHighlightingConfiguration.RULE_START_END_TAG);

But the highlighting doesn't work. Any sugesstions?

I've checked the offset and it's ok.

Thanks,
Timotei

Hi,

I don't know if this approach is going to work. As far as I know, the
reconciler is triggered only on a model change, i.e. not if merely the
cursor position changes.

Have you looked at the code that does the "boxing" the single character?
Maybe you can implement something similar for multiple characters.
Another hack would be to use the editors "reveal" method. Of course the
highlighting of the revealed area will be different from what you want.

The part with MatchingCharacterPainter doesn't work, as only 1 character can pe paint.

Hi Timotei,

did you try to call highlighting reconciler.refresh() to trigger the
reconciler?

Sebastian

Hi!
Nice, it works with .refresh(). However there is an issue: In my ISemanticHighlight, I've put some higlightings. And that override some of the highlighted previously area. Is any way I can... detect if I highlighted that portion before, and skip it in my ISemantic? Or better, how I clear my position list?

Thanks,
Timotei

So, basically i have the following:

[tohigh]

With my custom bracket matching I highlight: [tohigh]
But, my ISemanticHighlighter higlights this: tohigh

So, in the end it looks like:

[tohigh]

Basically I need a way to know if I should/or not use the SemanticHighlighter. One way I was thinking, can I extend the AbstractNode with a "better" class, and use that, instead of AbstractNode, in my xtext editor/other stuff? I would put another property, and based on that I would hihglight/or not with my SemanticHighlgihter.

Thanks,
Timo

I tried the following:

public class EnhacedLeafNode extends LeafNodeImpl

and then, in MYDSLUiModule.java:

	public Class<? extends LeafNodeImpl> bindLeafNode()
	{
		return EnhacedLeafNode.class;
	}

But that doesn't work, I get exceptions when the editor triies to be instantiated.

UPDATE:
I've tried another route to do this, with this:

	public Class<? extends MergingHighlightedPositionAcceptor> bindMergingHighlightedPositionAcceptor()
	{
		return WMLMergingHighlightedPositionAcceptor.class;
	}

But it neither works.

Do I miss something? It looks like guice can't "override" used classes, only Interfaces?

Hi Timotei,

it is not possible to change the implementation class of the node model.
However, you are free to attach information via leafNode.eAdapters().add(..)
