[XText] organize outline view [message #496196]

Hello *,

I'd like to re-organize the tree in the outline view of my DSL. I want to group
some enties in the outline. Imagine, something like the grouped imports in Java
Editor outline view.

How can I do this?

Ciao, Micha

I think the sample below is what you are looking for. I created a new rule for all the parts that I want to group together!

elements+=
  "Include:" includes+=Includes
| "Beliefs:" beliefs+=Beliefs
;

Includes:
	(include+=Include)+;
Include:
	includeName=ID;
Beliefs:
	(belief+=Belief)+;     
Belief:
	  atom+=Atom "."

Hope it helps you getting there!

Regards,
Tim

Hi Michael,

you may want to have a look at the generated MyDslTransformer in the
*.outline package in your ui plugin. It allows to customize the
structure of the outline view.

#newOutlineNode(parent, label, image, location) will help to instantiate
nodes that do not mirror a semantic object but are kind of virtual nodes
or logical groups.

Regards,
Sebastian

Hi Sebastian,

thanks for reply.

I found my DSL transformer. My problem is, that for every instance of Include
(subclass of EObject), the method is called. For every call a new group will be
created.

Is there a sample for virtual outline nodes?
(except for http://www.eclipse.org/Xtext/documentation/0_7_2/xtext.html# outline)

For example my XText model is:

Root :
Include | Service ;

All includes should be grouped into a virtual ContentOutlineNode. the sequence
of Services and Includes can be mixed, but the includes should be grouped at the
top of my outline.

Ciao, Micha

Hi Sebastian,

I have a similar problem like Michael.
I did not found a method newOutlineNode with the mentioned signature in AbstractDeclarativeSemanticModelTransformer. There is a method with this name but only two parameters.

Can you provide a code snippet that shows how to introduce virtual outline nodes?

Hi all,

the solution for the problem is to create a new node with newOutlineNode(semanticNode, parentNode)
for the semantic node you take the first node of the childnodes of the virtual node.

Hi everyone,
I know this is a very old topic and I don't want to annoy you all, but I have found that calling one of the constructors of ContentOutlineNode works.
Just instantiate a ContentOutlineNode with a label and set its parent in your Transformer class.
Here is a post.

Bye! Xtext rocks! Very Happy
