Hello peoples, I would like to be able to find the extensions that an Editor
can handle, programmatically.

Use case: Save as, when the user has not entered a file extension.

What is the best way to intercept the file name, and then add the correct
extension?

You can check if your IEditorInput is an instance of IFileEditorInput to
get the name. You can try
org.eclipse.ui.IEditorRegistry.getFileEditorMappings() from IWorkbench
and org.eclipse.core.runtime.Platform.getContentTypeManager() to see
what information is available.

Thanks Paul

I am trying IEditorRegistry.getFileEditorMappings(), like this:

IFileEditorMapping[] fileEditorMappings =
PlatformUI.getWorkbench().getEditorRegistry().getFileEditorM appings();
for (IFileEditorMapping mapping : fileEditorMappings) {
if (mapping.getDefaultEditor().getId().equals("myEditor"))
extension = mapping.getExtension();
}

I get an IEditorDescriptor, which has an getId() method. From here, how do I
get the ID for the current editor? IEditorPart has not getId() method...
