MCC is great, and I would love to be able to admin using it regardless
of whether I am using text interface or gtk/qt. The interface is
completely different in curses than gtk interfaces. Curses version is a
second rate citizen, and Gui is all GTK. A lot of the tools are not
available in curses interface, for instance, I don't see a way to
install software or managing repositories. It would be nice to have qt
version as well as gtk (not a major issue, but would be nice)
*Possible solution* I have thought how this could be addressed and feel
that in the long term, the best solution would be to have the interface
layer abstracted. So when developing a module, you use the mcc UI
library, so you may call for instance mccGui.pushButton then if you are
running in curses it creates a curses button, if you are in KDE it
creates a QPushButton, if you are in Gnome it creates a GTKButton. This
would take a great deal of work, so I started looking around to find any
existing libraries. The first place I looked was openSuSE as Yast does
exactly what I am describing. In yast, the interface is laid out and
works the same way whether you are using curses, Gtk or Qt. To my
surprise they have put a lot of work into separating their Ui library
from the Yast tools. You can use the library to write curses/gtk/qt
programs that use the appropriate widget as needed, independent of Yast.
We could use the Yast Back end, and adapt our front end to use it. This
option would take the least amount of work, as there are perl bindings
to the yast libraries, and so it would only be the gui layer that would
need reworking. The current gtk only modules could become curses/qt/gtk
modules by changing the gtk calls to yast backend calls.
Just to be clear, I am not suggesting that we port Yast to Mageia, I am
suggesting we use its Ui abstraction only. I use Mageia over openSuse
for many reasons, but I do admire how well Yast works, and would love to
see similar in Mageia. Perhaps we could start planning the next
generation of MCC ??
Why it would be good for Mageia to include it
It would provide consistency across terminal and gui administration, and
in doing so provide an easy entry into text based administration for
Providing the abstraction layer would mean all modules created will be
available to all users.
