Hello,

I try to retrieve the list of xtext files (*.ocl files in my case) present in the workspace and in plugins.
I have explored the trail of the "Ctrl + Shift + F3" action in the editor but it is not what I need... at all.

For more details about our use case:
users must have a way to see the list of xtext files which import the uri of their models. Our action is available by right clicking a model in the editor and the expected result must be a list of all registered xtext files which use the current model (in workspace and in plugins).

Is this doable using Xtext index??
Thanks in advance,
Marwa

Hi,

import the uri is a thing that is not stored in the index.
it stores
- which resources xtext knows
- which objects are exported by these resources
- there is a reference between two object (writing import "bla.blubb" is not such a reference...)

did you have a look at the find references command (you can call it on object in the editor, not files)

you could write something similar using the index

have a look at the index classes:

IResourceDescriptions
IResourceDescription
IReferenceDescription

Thanks Christian for your answer,
The 'which resources xtext knows' could be util in my case,
I am discovering the find references action, It seems very helpful for what I need to do
Regards

I have took a look at the code of the "findReferences" action.
The index Data contains just xtext files of workspace and not xtext files from plugins Sad
I think what I am looking to do is just not feasible using the index data, I will go directly for the plugin.xml solution.

Thanks again for your precious help

So you refer to resources in the workbench from within your workspace?
That doesn't sound like a good idea.
Are you sure don't want to use PDE's target platform and have those
bundles on your project's classpath?
