I need to get value "Directory" (output folder) from Compiler Preference/Property Page programmatically.

How can I do that?

And generally, how can I access to the preferences of Xtext Preferences/Properties pages such as Compiler, Refactoring etc.

You may want to use the IOutputConfigurationProvider to access the
values that can be configured by means of the output preference page.
The same applies for other settings, too: There is usually a service
available that provides their values.

Dear Sebastian,

Thank you very much for your reply.

I found IOutputConfigurationProvider, but I still can't understand how can I get the value?

I also tried to inject EclipseOutputConfigurationProvider and OutputConfigurationProvider which implements the interface, but they are both null.

How can I get current IOutputConfigurationProvider? What service can I use to get the provider and values?

Regards,
Sandra

Services such as an instance of the IOutputConfigurationProvider are
obtained by means of dependency injection. It is usually sufficient to
declare a field with an @Inject annotation. Please refer to the
reference docs and the Google Guice documentation for details.

Sebastian

As I mentioned in my previous post I already tried to inject:

@Inject
IOutputConfigurationProvider provider;

and:

@Inject
EclipseOutputConfigurationProvider provider;

and also:

@Inject
OutputConfigurationProvider provider;

But they are all NULL.
What am I doing wrong?

Regards,
Sandra

Hi Sandra,

sorry I do not see a single mention of the @Inject annotation in your
prev post. Somehow I missed that.

How do you obtain an instance of the class that has these injected fields?

Regards,
Sebastian

Hello Sebastian,

I need to get the value in my Eclipse Wizard class (MyDslExport) that implements IExportWizard.
I define the wizard using extension point org.eclipse.ui.exportWizard.

So, I am trying to inject the provider in MyDslExport class.

Probably, the provider is null because my MyDslExport is not injected but defined using eclipse extension point.
In this case, how can I solve it?

Regards,
Sandra
