What's your issue about?

The output when running with vyper -f interface or vyper -f external_interface.

In the interface output, events are shown, but whether their parameters are indexed or not is omitted. This is crucial information for parsing events so should be included.

In the external interface output, the events are not shown at all. I would argue that these are part of the external interface so should be included.

How can it be fixed?

I would guess the relevant information is readily available when printing these outputs, so the fix is simply to include them.
