I have changed the plugin.xml in ui package to disable the default triggering of xtend generator.
I have created "GenerationHandler" class in " org.xtext.example.mydsl.ui.handler" package.
My GenerationHandler class is:
======================================
package org.xtext.example.mydsl.ui.handler;
public class GenerationHandler extends AbstractHandler implements IHandler {
@Inject
private IGenerator generator;
@Inject
private Provider<EclipseResourceFileSystemAccess> fileAccessProvider;
@Inject
IResourceDescriptions resourceDescriptions;
@Inject
IResourceSetProvider resourceSetProvider;
@Override
public Object execute(ExecutionEvent event) throws ExecutionException {
ISelection selection = HandlerUtil.getCurrentSelection(event);
if (selection instanceof IStructuredSelection) {
IStructuredSelection structuredSelection = (IStructuredSelection) selection;
Object firstElement = structuredSelection.getFirstElement();
if (firstElement instanceof IFile) {
IFile file = (IFile) firstElement;
IProject project = file.getProject();
IFolder srcGenFolder = project.getFolder("src-gen");
if (!srcGenFolder.exists()) {
try {
srcGenFolder.create(true, true,
new NullProgressMonitor());
} catch (CoreException e) {
return null;
}
}
final EclipseResourceFileSystemAccess fsa = fileAccessProvider.get();
fsa.setOutputPath(srcGenFolder.getFullPath().toString());
URI uri = URI.createPlatformResourceURI(file.getFullPath().toString(), true);
ResourceSet rs = resourceSetProvider.get(project);
Resource r = rs.getResource(uri, true);
generator.doGenerate(r, fsa);
}
}
return null;
}
@Override
public boolean isEnabled() {
return true;
}
}
Problem:
==============
I dont know which all packages to import, since it is asking many packages.
Can any one suggests which all packages to import please...?
