Hey,
I have a couple of questions regarding gobject-introspection but with a
direct focus on pygobject. Instead of cluttering the mailing list with
multiple mails I thought I'd just post one. I hope that was alright.
I was under the impression that one of the many benefits of
gobject-introspection was that in the case of generating dynamic python
bindings we would also get automatically generated docstrings for
functions, classes and methods based on annotations resp. gtk-docs. From my
own tests, as well as from inspecting the dynamic bindings for gtk or
gstreamer, it seems this is not the case though. Is this the intended
behaviour?
Another issue I'm having is that functions defined in my module namespace
won't show up in the help for my module, e.g.
python2 -c "from gi.repository import MyModule; help(MyModule)"
doesn't list any of my implemented functions. They are properly annotated
in the C-code as they are listed in the gir file and I can call them just
fine from python. I noticed a similar behaviour for gstreamer functions.
Functions listed in the Gst-1.0.gir file are callable from python, but not
listed in the module's help text. Introspected classes, however, appear in
the help text. Why is that?
Another thing I was wondering about is if default arguments for functions
and methods are supported yet. Again, a gstreamer example: I've seen lots
of code snippets like
playbin = Gst.ElementFactory.make("playbin2")
on the net, even though according to the C documentation
gst_element_factory_make requires you to pass two arguments to the
function: the element you want to create and a unique name. The name
argument is annotated with allow-none, but I still have to pass None as
second argument if I call the method from python as otherwise a TypeError
exception is raised. This is what I would consider correct behaviour, but
I'm still wondering if all the code examples are simply erroneous or if I'm
overlooking something.
Kind regards,
Niklas
