EGL applied to compartments [message #1857304]

Hi there,

The code below transforms a diagram graphical object's content into text in an html table:

[%for (n in DiagramClassObject.DiagramClassObjectVal.DiagramClassObjectValCompartmentVal.sortBy(n|n.name)){%] <tr>
<td>[%=n.name%]</td>
<td>[%=n.type%]</td>
</tr>
[%}%]

However, there are undesirable sentences: "EolSequence"+square brackets and "OrderedSet".

index.php/fa/42867/0/

The cell contents should simply be "MyName" and "MyType".

Could you please help me resolve it?

Many thanks.

Hi Clever,

Could you provide a minimal example that reproduces this issue?

https://www.eclipse.org/epsilon/doc/articles/minimal-examples/

It's hard to provide any help when we don't have a full picture of the metamodel / model you're using.

Best,
Antonio

Thank you for your reply, Antonio.

I made changes to the example at https://www.eclipse.org/epsilon/doc/eugenia/ and managed to reproduce the problem. I noticed that when I call an attr "type" the message "OrderedSet" appears in the html output table. If I use the name "ttype" instead, the output is "EolSequence [NameIsNotType]" (see attached html file).

Version: index.php/fa/42888/0/

Metamodel (FS.emf):

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

@gmf.diagram
class Filesystem {
attr String name;
val Drive[*] drives;
val File[*] files;
}

@gmf.node(label = "name")
class Drive {
attr String name;
@gmf.compartment
val File[*] files;
}

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

EGL

<h1>Filesytem [%=filesystem.name%]</h1>

<table border="1">

[%for (n in filesystem.drives.files.sortBy(n|n.name)){%] <tr>
<td>[%=n.name%]</td>
<td>[%=n.type%]</td>
<td>[%=n.ttype%]</td>
</tr>
[%}%]

</table>

EGX

rule FILESYSTEM2HTML
transform filesystem : Filesystem {

template : "filesystem2html.egl"

target : "GeneratedText/filesystem" + filesystem.name + ".html"

}

From your original post and the launch configuration in your second one I think the issue is that you are navigating the GMF model not your EMF model. The default.filesystem_diagram is a model that contains the graphical information to show your model as a diagram. To generate text form your model you need to load the EMF model in the run configuration, that is your default.filesystem file. Note that behind the scenes GMF will update that model with any changes you do in the graphical editor.

Hi Clever,

filesystem.drives returns a collection, and therefore filesystem.drives.files returns a collection of collections. Flattening your nested collection with EOL's flatten() operation (i.e. filesystem.drives.files.flatten().sortBy(...)) should do the trick.

Thanks,
Dimitris
