Using linked .jar libraries in code generator [message #1767277] Tue, 04 July 2017 12:20 Go to next message

I have been trying to write a code generator, however the established compiler I am working from uses the javax.json library via a JAR file. I have added the JAR file to my project but when I run the Runtime Eclipse it generates a long series of errors about the JAR file being missing. I have already added it to build.properties. Do I need to add it to the MWE2 file or to plugin.xml somewhere?

Hi,

Ah, ok. Adding it to runtime worked. But doGenerate apparently never runs.

yes that is intended. for your libary no code is generated. only for sources in the project

Sorry but I don't understand that response at all. The only library I talked about was the JSON library. Of course no code would be generated for that, it is not written in my DSL. In the runtime eclipse I have a DSL-project with DSL-sources in it. Nothing is generated for them and according to a println I put in doGenerate(), it is never being called. The getRelevantDeltas method has no documentation that I could find. Is generation not run by default? If there is something extra that needs to be done to make the code generator run could it be added to https://eclipse.org/Xtext/documentation/303_runtime_concepts.html ?

well i get nice code generated for

entity X extends demo {

}


import org.eclipse.xtext.xbase.lib.Procedures.Procedure1;
import org.eclipse.xtext.xbase.lib.util.ToStringBuilder;

@SuppressWarnings("all")
public class X extends demo {
public X() {
}

public X(final Procedure1<X> initializer) {
initializer.apply(this);
}

@Override
public String toString() {
String result = new ToStringBuilder(this).addAllFields().toString();
return result;
}
}


so i have no idea what you are talking about.

- sure model is in source folder
- build automatically is on
- project has xtext nature and xtext builder?

p.s:

in xbase you usally implement JvmModelInferrer and no generator
so i am not sure which prinltn you are referring to?

Ah, sorry, the DSL does not compile to Java so I have written a Generator class.

Edit: The project doesn't seem to have a Builder configured, there doesn't seem to be a project type generated for the DSL. The 15 minute tutorial says to use a Java project so I tried one of those, but the generator still isn't running. There's only two options for the Builder, Ant Build and "Program", there doesn't seem to be an option to run the XText-created Generator.

Also I noticed that in the documentation at https://eclipse.org/Xtext/documentation/303_runtime_concepts.html it omits the IGeneratorContext parameter in the example.

if you create or open a .yourdsl project xtext asks if you want to add the stuff
you can do a rightclick on the project -> configure -> xtext project as well

Ah, ok, the right click worked. Thanks! Sorry, it is a bit confusing to have this called an "Xtext project" when the project it is not written in Xtext.
