xtext：除了Eclipse编辑器外，如何使用语法？

Question

I am trying to use the example org.eclipse.xtext.example.arithmetics.Arithmetics with xtext. I can run the Eclipse Application as described in the 5-minute tutorial and 15-minute tutorial , so the editor will do syntax checking.

But how do I actually use the model in a Java app? (I'm not talking about code generation)

I found this FAQ entry . But which .jar files do I need to include in my build path? There are a lot of unresolved classes here.

new org.eclipse.emf.mwe.utils.StandaloneSetup().setPlatformUri("../");
Injector injector = new MyDslStandaloneSetup().createInjectorAndDoEMFRegistration();
XtextResourceSet resourceSet = injector.getInstance(XtextResourceSet.class);
resourceSet.addLoadOption(XtextResource.OPTION_RESOLVE_ALL, Boolean.TRUE);
Resource resource = resourceSet.getResource(
    URI.createURI("platform:/resource/org.xtext.example.mydsl/src/example.mydsl"), true);
Model model = (Model) resource.getContents().get(0);

Answer 1

These are the dependencies I found:

<classpathentry kind="lib" path="D:/gabor/eclipse2/plugins/org.eclipse.emf.mwe.utils_1.2.1.v201112070431.jar"/>
<classpathentry kind="lib"  path="D:/gabor/eclipse2/plugins/org.eclipse.xtext_2.2.1.v201112130541.jar"/>
<classpathentry kind="lib" path="D:/gabor/eclipse2/plugins/org.eclipse.emf.ecore_2.7.0.v20120127-1122.jar"/>
<classpathentry kind="lib" path="D:/gabor/eclipse2/plugins/org.eclipse.emf.common_2.7.0.v20120127-1122.jar"/>

And the dsl project with the generated sources of course. Not a nice solution, I pressed ctrl-shift-t, searched for the missing classes, and the list showed in which jars does eclipse find that class, and then I added that jar as External Jar to my classpath.

如果您不想自己查找所有依赖项jar，则可以在Project-> Export-> Java-> Runnable Jar文件上单击鼠标右键，以帮助收集所有依赖项jar
