How to open model file in text editor programmatically [message #1807259] Mon, 27 May 2019 02:19 Go to next message
Eclipse UserFriend
Hi,

I want to open a xtext model file in text editor in some conditions.

File ->OpenWith works fine, but I want to achieve this programmatically.
When user double clicks on the file. I want to check some condition and if true, I want to open that file in text editor.

How can I achieve this ?


Thanks and regards,
Virag Purnam

Hi Mr. Christian Dietrich,

Do you have example?
Where should I call this to override association.
Can I call from NatureAddingEditorCallback.java ?

Thanks and regards,

And you don't call it. You simply implement it.
It will be called if you open a file
And then you can tell it to open with another editor
Instead of the all

Hi Mr. Christian Dietrich,

I have implemented IEditorAssociationOverride after using that extension point but it is not getting called when I open file.

Any idea?

<extension
          point="org.eclipse.ui.ide.editorAssociationOverride">
       <editorAssociationOverride
             class="CustomEditorAssociationOverride"
             id="customEditorAssociationOverride">
       </editorAssociationOverride>
    </extension>


Thanks and regards,

In implementation.
I just added some sysout to check if control comes there.

public class CustomEditorAssociationOverride implements IEditorAssociationOverride {

	public CustomEditorAssociationOverride() {
		// TODO Auto-generated constructor stub
	}

	@Override
	public IEditorDescriptor[] overrideEditors(IEditorInput editorInput, IContentType contentType,
			IEditorDescriptor[] editorDescriptors) {
		// TODO Auto-generated method stub
		System.out.println("Virag");
		return null;
	}

	@Override
	public IEditorDescriptor[] overrideEditors(String fileName, IContentType contentType,
			IEditorDescriptor[] editorDescriptors) {
		// TODO Auto-generated method stub
		System.out.println("Virag1");
		return null;
	}

	@Override
	public IEditorDescriptor overrideDefaultEditor(IEditorInput editorInput, IContentType contentType,
			IEditorDescriptor editorDescriptor) {
		// TODO Auto-generated method stub
		System.out.println("Virag2");
		return null;
	}

	@Override
	public IEditorDescriptor overrideDefaultEditor(String fileName, IContentType contentType,
			IEditorDescriptor editorDescriptor) {
		// TODO Auto-generated method stub
		System.out.println("Virag3");
		return null;
	}

and you should return editorDescriptors
(or the specific one if you want to change)

Hello Mr. Christian Dietrich,

But still these methods are not getting called, when file is opened.
Do you see any mistake from my end ?

Hi Mr. Christian Dietrich,

I have created a sample Xtext project for the same.

Grammar:
grammar org.xtext.example.mydsl.MyDsl with org.eclipse.xtext.common.Terminals hidden(WS, ML_COMMENT, SL_COMMENT, TEST_STMT)

generate myDsl "http://www.xtext.org/example/mydsl/MyDsl"

Model:
	conts+=Cont* procs+=Proc*;
	
Cont:
	'Cont' name=ID '{' items+=Item* '}' ;

Item: 'Item' name=ID;


Proc:
	'Link' item1=[Item|ID] 'OF' con1=[Cont|ID] 'TO' item2=[Item|ID] 'OF' con2=[Cont|ID]
;

//Test  statement
terminal TEST_STMT :  'FreeText: ' ->  '.';

}


Model file:
Cont container1 {	
	Item item1
	
}

Cont container2 {
	Item item2
}  

Link item1 OF container1 TO item2 OF container2



Thanks for your continuous help.
