[SailfishDevel] [WIP] Wayland Nemo VM Image (and new Nemo UI)

Hello people!
Here are some news for you, I wrote few paragraphs, with titles to help you
skim through the email in case you don't have much time to read it ;)


WAYLAND VM IMAGE UPDATE:

I didn't know anything about systemd, I didn't know anything about RPM
packaging, but I studied some stuff during last days, and now we have a
working Nemo Wayland image for VM!
The VM image boots to a QtQuick2/Qt5 homescreen (lipstick-colorful-home-qt5
package), and uses a Wayland QML compositor!
So now we have a VM image with a working homescreen (in early stages) and a
Wayland compositor!
Now that the we have something to base the rest of our work on, we need to
do some planning.



NEMO RESTYLING PLAN:

I'll share here the results of few chats with other Nemomobile guys
(qwazix, Sfiet_Konstantin, Hurrian, sorry if I'm forgetting anyone here)
and Jolla guys (Stskeeps, special, w00t,...):
1) First of all, we decided it was a good idea to port all Nemo QML apps to
Qt5/QtQuick2 and have them working on the new Wayland-based VM image;

2) Once all the core apps are ported to Qt5, we can start building the new
components sets (which will likely be QtQuickControls + custom controls)
which will be used to bring to life the new Glacier UI (if you don't know
what Glacier UI is, ---> http://play.qwazix.com/grog/?p=344 )

3) Once we have a working components set, we can port all Nemo QML apps to
the new components set created in step 2.

4) Test and bugfix

5) Enjoy the new Nemo with Glacier UI :D




CURRENT STATUS:

We're at step 1! We're porting all Nemo apps to QtQuick2/Qt5 using
com.nokia.meego components which have already been brought to QtQuick2 by
w00t.
I'll tell you what I know about the current porting status of the apps:
- special has already partially ported fingerterm (terminal emulator), and
qmlmessages
- I (faenil) have ported qmlcalc, the calculator, probably the easiest app
to port, which will be used as an example for those who want to know what
it means to port Nemo apps to QtQuick2
- the rest of the apps needs porting!




HOW CAN I HELP?

We're at step 1, so we need help porting all Nemo apps to Qt5/QtQuick2!
It's not much work! Don't feel like you're not expert enough do that,
anyone with some QML experience can help! :)
Here's an example of Qt5 port
https://github.com/nemomobile/qmlcalc/pull/11

As you can see it's mostly about renaming classes, changing few calls, and
then adapting the packaging files to the changes.


WHAT IF I DECIDED I WANT TO HELP?
Contact me, I'm faenil on #nemomobile IRC channel (freenode server).
I'll help you setup the wayland environment, so you can start hacking right
away! :)


This is all people!
Have a nice day! :)
