How to add copyright headers to generated sources [message #793531]

First I have to ask if I am allowed to add a copyright header to the generated Xtext sources.

Concerning the EMF generator I found a statement from Ed Merks
(see http://www.eclipse.org/forums/index.php/t/17839/).

Quote:

... in my opinion the input to the generator is your intellectual property, has your copyright and your license, and the generator injects nothing into the result. I.e., it's no different than a compiler generating byte code. This has always been my and IBM's position for the EMF generator, so for that I can make the statement definitively.

Is this also true for the Xtext generator?

Then the technical question:
Is there a recommended way to extend the generator to add a specific header to all generated files ?

Thanks in advance.
Harald

A look at org.eclipse.xtext.xbase.compiler.JvmModelGenerator suggests there's no built-in way to do this. But you can always extend that (Xtend) class, override the generateType function to include a copyright header and re-bind the extended class to IGenerator in .ui project.

Hi Harald,

you are free to add whatever header you want to your files. But as
Meinte already pointed out, there's currently no hook that explicitly
takes care of that. Please feel free to file a ticket.

Regards,
Sebastian

Probably we could extend a kind-of-similar one that I filed: https://bugs.eclipse.org/bugs/show_bug.cgi?id=368296

Thoughts?

Thanks,

Hi,

just wanted to follow up, has there anything been done on the topic of adding headers to generated files? The ticket that has been mentiones doesn't say it's been implemented.

Thanks,
Tobi

What about simply adding a custom xpand post processor to the
generator component in the GenerateYourDsl.mwe2 workflow

I'm not sure if I understand correctly but what about java files generated from my xtend files? Do I have influence on the generation process there?

Just to clarify, when I have a [name].xtend file in my workspace that, when changed, regenerates a corresponding [name].java file in the xtend-src firectory, that java file can't have a licence header added to it?
