[xtext2 xtend2] How to generate one file based on multiple models? [message #698644]

As an xtext beginner I managed to get the Statemachine example working. I added the generation of html to the example to test Xtend. My test project generates 1 statemachine html file per statemachine model.

This is achieved by my .xtend file:

class StatemachineGenerator implements IGenerator {
override void doGenerate(Resource resource, IFileSystemAccess fsa) {
fsa.generateFile(resource.className+".html", toHtmlCode(resource.contents.head as Statemachine))
}
...
}

testA.statemachine => testA.html
testB.statemachine => testB.html
testC.statemachine => testC.html

Now I would like to generate an index.html file that links to all my statemachines. I would like to iterate through all statemachine models in the 'context' / classpath.
What would be the best approach? Can I prevent generating the index.html file 3 times?

Thank you, Martijn

I implemented the solution from Karsten's blog. It works like a charm, thank you.

Hi,

I'm trying to follow the instructions of the blog, but for a beginner as I am, it's not obvious for me where I should introduce those changes.
Which files should I change or create?

Many thanks,
Carmela

Hi,

its quite easy:
create IGenerator2 (in the runtime plugin or somewhere on the path of the runtime module) and JavaProjectBasedBuilderParticipant2 (in the UI plugin or somewhere on the path of the ui plugin). change DomainmodelGenerator in the Runtime plugin.
change DomainmodelRuntimeModule and DomainmodelUiModule
