[Epsilon] Launch EVL validations programmatically [message #384260]

Hello,

I'm trying to launch EVL validations programmatically. I found an example
of how to run EOL from java, and I'm using it for loading de EMF model and
setting its properties. I made some proofs with EOL to ensure the correct
loading and now I'm defining an EvlModule.

It's OK? Or is there an easier way to do it? How do I set the evl file
that contais the validation to the EvlModule to execute it?

Thanks,
Héctor

Hi Héctor,

You can find an example of launching EVL programmatically at
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.gmt/eps ilon/examples/org.eclipse.epsilon.examples.standalone/src/or g/eclipse/epsilon/examples/standalone/evl/EvlStandaloneExamp le.java?revision=1.1&root=Technology_Project&view=ma rkup

Cheers,
Dimitrios

Many Thanks!

Now I'm trying to modify the code to work with metamodel URIs (no file
based)

Thanks,
Héctor.

To do this you'll need to modify

properties.put(EmfModel.PROPERTY_METAMODEL_FILE,getFile(meta model).getAbsolutePath());
properties.put(EmfModel.PROPERTY_IS_METAMODEL_FILE_BASED, "true");

to the following :

properties.put(EmfModel.PROPERTY_METAMODEL_URI,YOUR_URI_HERE );
properties.put(EmfModel.PROPERTY_IS_METAMODEL_FILE_BASED, "false");

Dimitrios

Hi,

When I try what you said I get these errors:

/*********************************************************** *****************/
URI: http://prueba/1.0 (This line is the output for:
System.out.println("URI: " +
properties.getProperty(EmfModel.PROPERTY_METAMODEL_URI));

I have tried many ways to convert the uri, changing the type of the input
parameters of createEmfModel(), then converting the URI.tostring()...but I
can't make it work. I'm doing something wrong? I mean, does it work for
you or it's a bug?

Thanks!
Héctor

Have you registered the metamodel you are trying to use first? When
running Eclipse, metamodels get registered automatically (either via EMF
itself or via the Register EPackages menu). When running standalone you
have to register your metamodels before you can reference them by URI.

I've uploaded an example of registering a metamodel and then using it
from Epsilon on the CVS
(examples/org.eclipse.epsilon.examples/standalone/src/org/ec lipse/epsilon/examples/standalone/eol/EolStandaloneMetamodel ByUri.java)

Cheers,
Dimitrios

Ok, now it works :)

Before I registered packages with right click -> Register EPackages.

Thanks a lot!

I'm sorry, I was wrong, the problem remains.

Maybe it's becuase of the version of the plugins? I've noticed that in the
examples your imports are like: org.eclipse.epsilon.* and mine are
org.epsilon.*...

I've checkout the CVS plugins and noticed than version of that plugins
(the name is like the ones you use in your examples) are 0.8 while the
ones I downloaded from you update site are 1.36

Is there any imcompatibility?

The errors I get are:

Hi Héctor,

As strange as it may sound, 0.8.0 is newer than 1.3.6. The reason is
that Epsilon now conforms with the incubation process which (among other
things) requires version numbers to be < 1.0 and the namespace change
you noticed (org.epsilon.* -> org.eclipse.epsilon.*).

We haven't built a binary version of 0.8.0 yet - but this will happen
within the next couple of days. If you can't wait until then, I'd
suggest checking out the code from the CVS (which btw I think is
generally a better idea as you'll be able to pick up future features and
bug-fixes faster).

Cheers,
Dimitrios

I see. I have already checkout the plugins from CVS, so next step is
changing the plugin dependeces and the imports to the newer version. If I
can't make it work, I will wait for the binaries.

Many Thanks!
Héctor
