How to enable introspection

[Ambrevar]

When I run D-Feet to introspect the object, it appears in the object list on the session. When I click on it however, I get the following error message:

Missing method-call handler at path / interface
org.freedesktop.DBus.Introspectable name Introspect (36)

Do I need to do something special to enable introspection or is it simply lacking in this library?

Support for introspection is not currently implemented in this repository.
There is a fork by @phmarek that has a WIP implementation. [0]
There is also the note I wrote a while ago [1].
I don't currently use dbus, but patches are welcome.

On a similar topic, is it possible to use this library to call the method of an object that does not expose any introspection element?

The only way I know to call methods using this library is to introspect objects as follows:

(dbus:with-open-bus (bus (dbus:session-server-addresses))
    (dbus:with-introspected-object (object bus +object-path+ +name+)
      (apply #'object +interface+ method args)))

I've managed to call an object method without introspection like this:

(dbus:with-open-bus (bus (dbus:session-server-addresses))
    (let ((object (dbus/introspect::make-object
                   (dbus:bus-connection bus) +core-object+ +core-name+
                   (list (dbus/introspect::make-interface
                          +core-interface+
                          (list
                           (dbus/introspect::make-method "make_buffers"
                                        "as"
                                        '("urls")
                                        '("as")
                                        '()))
                          nil nil)))))
      (apply #'dbus:object-invoke object +core-interface+ method args)))

This requires access to a lot of unexposed methods. I believe that introspection is not a requirement of D-Bus and in fact glib's dbus API supports them (that's how I can call Common Lisp methods).

So what about exposing a convenience function that roughly does the above?

If you don't want to use introspection, use dbus:invoke-method.

Thanks! I will send a pull request for a documentation update listing the most useful methods and some more examples.
