Re: glibmm: Creating a DBus namespace?

[Milosz Derezynski <internalerror gmail com>]

Thanks, Chris, yes it is actually the other way around.

Also, your point about "Glib::Gio" seems pretty valid to me, but I guess it would be too much to ask for right now. (Does the existence of ::Gio still stem from the time when it was separate from Glib?)

Perhaps this could be an issue for 3.0 (to move ::Gio into Glib::)?

That is how glib does it, rather than an inconsistency.  The glib
tarball comes with a number of other modules apart from gio, such as
gobject, gthread, gmodule, all with their own pkg-config *.pc set-up
files and (apart from gmodule) with their own separate documentation,
which also all use the G and g_ namespace prefixes.

It is glibmm which has an inconsistent usage, by separating off only
gio into a separate namespace (which incidentally is ::Gio, not
Glib::Gio), which may be the source of what you find confusing.  There
seems no particular reason why there should not be GThread, GObject and
GModule namespaces in glibmm: the defining feature of course is that gio
contains vastly more code than would these others namespaces.

However modularising glibmm is in my view a good thing, so Gio::DBus
sounds fine to me.  But why restrict this to just one subset of gio,
namely gdbus? As I say, there is a great deal more namespace modularity
which could sensibly be implemented in glib.
