Hi to all,

I want to migrate my mwe workflow to mwe2.

I have several links to fragment files of the kind:

<language uri="foo.xtext">
<fragment file="/bla/StandardFragments.mwe"
</language>

How can I model this external fragment files?
Do you have a migration guide somewhere?

Thanks in advance
Cheers
Markus

HI,

the <bean file=""> pattern is not supported in mwe2. mut you can import / reference stuff like... (although i dont know anyone who actually does this)

second.mwe2

module a.b.c.DModule

org.eclipse.xtext.generator.serializer.SerializerFragment auto-inject {
	generateStub = false
}

main.mwe2

import a.b.c.DModule
...
fragment = @DModule {
    			
    		}

...

but why not simply inlining them?????

Hi Christian,

we have multiple plugins which are using the same fragments, so we defined the common fragments in a separate mwe file.

One more question... In the included file I define e.g.:

// <fragment class="org.eclipse.xtext.generator.resourceFactory.ResourceFactoryFragment"
// fileExtensions="${fileExtensions}"/>
fragment = ResourceFactoryFragment {
fileExtensions = auto-inject {} -> don't know if auto-inject is correct here
}

The property fileExtensions was set in the calling mwe script before, like
<fragment file="bla/StandardFragments.mwe" fileExtensions="xtextdoc"/>

Can I set fileExtensions to parameterize the call with mwe2, too?
How do I have to reconfigure the following line:
fragment = @ StandardFragments {}

Thanks for all your help
Cheers
Markus
