[Qemu-devel] [PATCH for-2.9 25/47] qapi2texi: Include member type in generated documentation
Posted by Markus Armbruster 8 years, 7 months ago
The recent merge of docs/qmp-commands.txt and docs/qmp-events.txt into
the schema lost type information.  Fix this documentation regression.

Example change (qemu-qmp-ref.txt):

  -- Struct: InputKeyEvent

      Keyboard input event.

      Members:
-     'button'
+     'button: InputButton'
           Which button this event is for.
-     'down'
+     'down: boolean'
           True for key-down and false for key-up events.

      Since: 2.0

In which case is this expected to happen? place an assert here instead?

Definitely worth having.
