generator output relative to dsl file [message #1857216]

Hello everyone,

I want to generate the src-gen folder next to my dsl file. The problem is that I have mutliple dsl files in my project. Is there a way that I can define the OutputConfiguration to do this?

I have seen that there exsists a IContextualOutputConfigurationProvider but I can't get this to work. If I understood that correctly, I would then overwrite the default output configuration for each resource every time I want to generate the code. That might not be perfect but might work.

When I generate the files "manually" in the generator ( generate file at location: resource.URI / generatedFile ) I get problems with deleting old files. In this scenario I have an OutputConfiguration with output folder: "." (the project root)

Thank you for helping!

Hello Christian,
For example I have this project structure:

https://tree.nathanfriend.io/?s=(%27options!(%27fancy8~fullPath!false~trailingSlash8~rootDot8)~A(%27A%27Root0514052B1G*othCEsB2G7*9*60534%27)~vCsion!%271%27)*%20%200%5Cn*407965foldC6**genCatedE7*mydsl.dslG8!true9src-gen0Asource!BGsub5CerEFileG0*%01GECBA9876540*

And I only want to have for each mydsl.dsl file the src-gen folder next to it.

Hey,

sorry for the late response.
There are reasons that are kind of stupid but it is what it is. That's unfortunately nothing that I can change. But back to the topic.
I found kind of an solution:

@Override
	public Set<OutputConfiguration> getOutputConfigurations(ResourceSet context) {
		Set<OutputConfiguration> set = new HashSet<>();
		set.add(OutputConfigurationProvider.DEFAULT());
		for (Resource res : context.getResources()) {
			OutputConfiguration outputConfiguration = new OutputConfiguration(res.toString());
			String path = res.getURI().toPlatformString(true);
			path = path + "folder";
			outputConfiguration.setOutputDirectory(path);
			outputConfiguration.setCleanUpDerivedResources(true);
			outputConfiguration.setCanClearOutputDirectory(true);
			outputConfiguration.setOverrideExistingResources(true);
			outputConfiguration.setCreateOutputDirectory(true);
			set.add(outputConfiguration);
		}
		return set;
	}

this is the output configuration and this is how I generate my files:

fsa.generateFile("pom.xml", resource.toString, generatePom(""))

So I generate my files for a resource with the right OutputConfiguration.
The problem I have now is that the old files are not deleted. I thought that is what setOverrideExistingResources does.
Does anyone knows a solution? Thanks!

i still dont understand: why not generating to a top level src-gen. which usecase do you solve by generating next to the file
for the incremental deletion you need to debug
the code in BuilderParticipant.getDerivedResources
