Hi,

I'm the main developer of Javascript for EMF (JS4EMF) and think it would
be interesting to add support for Javascript queries to Modisco, based
on JS4EMF.

What should I read and do to implement this?

Hi Hallvard,

First, thanks a lot for your interest!
I agree it would be a really nice contribution to MoDisco.
To have more information on the MoDisco Query Manager, you can take a look to the available general documentation from http://wiki.eclipse.org/MoDisco/Components/QueryManager/Docu mentation/0.9 to get an overall idea.

For the implementation part, there is already an example of such an integration of a query language: JXPath.
You can take a look to the source code of the corresponding org.eclipse.gmt.modisco.infra.query.jxpath plug-in which is available from the MoDisco SVN.
There, you will have a concrete example of the extension points to use and interfaces to implement.
More information can also be found from the Javadoc of the org.eclipse.gmt.modisco.infra.query and org.eclipse.gmt.modisco.infra.query.core plug-ins.

I hope this help.
And don't hesitate if you need more information.

Best regards,

Hugo

Thanks, that was what I needed. Based on this example I've implemented a
Javascript-based model query factory and adapter. It seems to work well.

Two questions:
- Do you have a test setup, so I can write an automated test instead of
just claiming it works?
- How to contribute the implementation?

Hi Hallvard,

Great!

Concerning the tests, you can find from the MoDisco SVN "tests" folder some projects providing tests on queries: org.eclipse.gmt.modisco.infra.query.tests for general tests on queries and org.eclipse.gmt.modisco.java.queries.tests for testing queries on a Java model.
Similarly, you could use a Java model to build your test plug-in...

Concerning the contribution of your implementation, here is some general information: http://wiki.eclipse.org/MoDisco/How_to_contribute
Basically, you will need to create a MDT-MoDisco "Contribution" bug and attach your plug-ins to it for initiating the process.
