XText Binding Generators from another Project [message #1796265]

Tue, 09 October 2018 07:56

When I start a new XText Project, and then generate the XText Artifacts from my XText File, A RunTimeModule is automatically created in the core logic Project where the xtext File defined, so that I can bind my own generators and validators.

Depending on my workflow, XText also automatically creates packages for generators and validation, also within this core Project.

Let's say I have another Project, where additional generators are defined, and this Project is dependent on the core Project where my RunTimeModule is.

But the core Project itself of course has no access to this second Project.

How can I bind these generators in this second Project, since in my RunTimeModule I have no access to these other generators?

To make it clearer

org.xtext.myDsl (Core Xtext Project)
    ---- org.xtext.myDsl
             ----MyDsl.xtext
            ----MyDslRuntimeModule.xtend
    ---- org.xtext.myDsl.Generator
    ----- org.xtext.myDsl.validation

org.xtext.second.myDsl (second Project dependent on org.xtext.msDsl)
      --- org.xtext.second.myDsl.generator (I want to bind the generators here)

the generators are "found" via the

<extension point="org.eclipse.xtext.builder.participant">
<participant
class="org.xtext.example.mydsl.ui.MyDslExecutableExtensionFactory:org.eclipse.xtext.builder.IXtextBuilderParticipant"
fileExtensions="mydsl"/>
</extension>

extension point.

so you could do this with a custom MyDslGeneratorExecutableExtensionFactory (+ Activator + Bindings etc)

For standalone:

it depends on how you want to call the generators

which usecase do you target: eclipse or standalone?

Standalone

I am building an VS-Code Plugin

then this wont work.

do you call the generator automatically or via command?
in both cases you need to make sure you call a composite generator in the end
(IGenerator2 that delegates to all generators you have)

I want the generators to be called every time I save the file Visual Studio Code

so I guess then the only way is to bind the generator like this

	// contributed by org.eclipse.xtext.xtext.generator.generator.GeneratorFragment2
	public Class<? extends IGenerator2> bindIGenerator2() {
		return MyDslGenerator.class;
	}

So I need a main IGenerator2 delegate that delegates to all my generators within the doGenerate method right?

allows me to process resources that are built by an Eclipse Project Builder.

But I cannot use this with VS-Code right?

Do you perhaps know if something similar exists for VS-Code?

no in viscode you have to have a single IGenerator2
(you have create a delegating one in yourdsl.ide though)
