EVL
****

I generated edit,editor,diagram code from eugenia using the filesystem emfatic file

described here http://www.eclipse.org/epsilon/doc/articles/eugenia-gmf-tutorial/

But My evl was not working in the eclipse instance. ( I followed every instr in the evl article)

But then I checked out the org.eclipse.epsilon.eugenia.examples.filesystem.*
example from SVN and compared it with eugenia generated code and found that it had additional packages/classes/different content

Like., filesystem.diagram.view.factories new package in (Diagram) &
filesystem.presentation.FilesystemEditor ( Editor ) content is different from the one generated from emfatic.

Kindly let me know What I am missing while generation.

Hi,

Does validation work for you in the unmodified filesystem example (org.eclipse.epsilon.eugenia.examples.filesystem.* in the SVN)? To test this, you can create a file element with an empty name in your GMF editor, and then validate your model (this should produce an error marker on the file element). The example in the SVN has been developed using an older version of GMF so I suspect that the differences you're observing in terms of the generated code are the result of (hopefully backward-compatible) changes to the GMF generator.

Cheers,
Dimitris

Yes validation work for me in the unmodified filesystem example (org.eclipse.epsilon.eugenia.examples.filesystem.* in the SVN)?( On save ).
( But the Validate option > Diagram menu is missing )

But the below doesn't work

My emfatic file,

@namespace(uri="bank", prefix="bank")
@gmf
package banking;

@gmf.diagram
class Bank {
val Customer[*] customer;
}

@gmf.node(label = "name")
class Customer {
attr String name;
}

My Evl file,

context Customer {

critique NameStartsWithCapital {

check {
var nameToUpperCase = self.name.firstToUpperCase();
return nameToUpperCase = self.name;
}

message : 'Customer ' + self.name +
' should start with an upper-case letter'

fix {
title : 'Rename to ' +
self.name.firstToUpperCase()
do {
self.name := self.name.firstToUpperCase();
}
}
}
}

My plugin.xml of CheckEVL.validation project

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.2"?>
<plugin>
<extension
point="org.eclipse.epsilon.evl.emf.validation">
<constraintsBinding
constraints="validation/Bank.evl"
namespaceURI="bank">
</constraintsBinding>
</extension>
<extension
point="org.eclipse.ui.ide.markerResolution">
<markerResolutionGenerator
class="org.eclipse.epsilon.evl.emf.validation.EvlMarkerResolutionGenerator"
markerType="CheckEVL.diagram.diagnostic">
</markerResolutionGenerator>
<markerResolutionGenerator
class="org.eclipse.epsilon.evl.emf.validation.EvlMarkerResolutionGenerator"
markerType="org.eclipse.emf.ecore.diagnostic">
</markerResolutionGenerator>
</extension>

</plugin>

And in build.properties validation folder is selected.

I did not add any entries to edit,editor,diagram,model projects ( left as generated from emfatic file)

But Customer is not getting validated on save/ Diagram > validate is not found either.

Thanks for the quick reply kindly Help!

Thanks,
Shrikanth NC

Hi,

In recent versions of GMF, the Validate action has moved under the Edit menu. Copying from [1]:

> To validate this we go to the Diagram menu and select Validate (if you are running Galileo, the Validate option is under the Edit menu instead). The editor now looks like this:

To get the on-save validation behaviour, you'll need to modify the generated code as discussed in the "Recipes" section of the article [1].

Cheers,
Dimitris
