Hi,
Is there an easy way to serialize an EMF model represented by an
XtestResource to XMI? I really would like to use Xtext in order to describe
my ecore models in a textual way but still store it as XMI (or as a text
file depending on the user). Do I need to write a custom Serializer in order
to achieve that?
Regards,
Thomas.

Hello Sebastian,
as far as I understood it, in this case, every graphical information, or,
everything, which is not modelled, like comments, line breaks, spaces, is
not serialized and therefore lost.
Is that correct?
Ciao, Michael

You might want to take look at the docs section under hidden terminal
symbols, as well as look at the bits on whitespace. By modifying that
stuff you can make any of these typically ignored tokens semantic and
thus have them included in your model. Of course at some point then you
may as well have your model in plain text. :) But I can see where it
makes sense to do this kind of thing if you want to be able to
reconstruct an entire piece of user code from a well structured
artifact.

Hi Michael,
this is correct. As whitespace and comments are not part of typical
semantic models, they get lost when you serialize your model as XMI.
You may try to serialize the attached node model as xmi to keep all this
information. Have a look at NodeUtil.getNodeAdapter(eObject).
Regards,
Sebastian

Hi,
where do I get the XtextResource instance from? I tried the following in the
UI-plugin but did not succeed:
private XtextResource
getXtextResource(org.eclipse.core.ressources.IResource resource) throws
IOException{
XtextResource xtextRes = new XtextResource();
xtextRes.load(new FileInputStream(resource.getLocation.toFile()), new
HashMap<String,String>());
return xtextRes;
}
The problem is that the parser is not injected into the XtextResource which
results in a NullPointerException in the "doLoad" method.
Do you have a hint for me?
Regards,
Thomas.

Hi Thomas,
from the usage of an IResource, I assume you are executing your code
inside of Eclipse. All you need to do to instantiate a resource, is to
create a resource set and use #getResource(URI).
XtextResourceSet set = new XtextResourceSet();
return set.getResource(.., true);
Xtext used EMF and google guice to do some difficult stuff, like
injecting the parser or finding the right resource factory for your file
extension.
Hope that helps,
Sebastian
