Suggested Usage

I put the entire Anjuta project into subversion. If you’re developing then here’s what I’d do as there are absolute paths stored in the Anjuta configs.

1. Create a new VALA project in Anjuta
2. Grab the vala files from Subversion along with the .glade and .ui files
3. Add in the references at project level (right click in Anjuta and add:

–pkg gtk+-3.0 –pkg gdk-3.0 –pkg gdu –pkg gee-1.0 –pkg liboobs-1 –pkg libxml-2.0 –pkg pango –pkg pangocairo –pkg posix –pkg gconf-2.0 –pkg gstreamer-0.10 –pkg

4. Add the libs to the EXOGENESIS build (right click and choose NEW LIBRARY).

5. As this is a test config there is a hardcode path in main.vala ( change to your dev location).

6. There is an array of windows in fexomainwin.vala, this is the flow of windows for navigation. Basically the screens are made up from the following:

i. App creates a main gtk3 window and adds in 1 box.
ii. Screens are read from glade (exogenesis.ui) file. Basically, these are boxes added as top level items. The reference to the box is added/removed to the box on the main Gtk window.
iii. Utility functions are loaded globally.
iv. A global reference exists to gInstallData, this holds all install information that will be applied. This includes user and group information, disk partitioning, language and timezone config.

If you have any questions then please get in touch, it’ll be easier to ask rather than try to work it out.

Having worked on the Aurora installer over Christmas (when time and sobriety allowed ) all Exogenesis screens and widgets have been ported to Gtk/Gdk3. The move caused a few issues, especially with the Gtk part of the Gdu API. Most of these issues have been sorted and custom widgets written to replace those implemented by Gdu-Gtk/2. The core of the Gdu interface ported with no problems.

During the rework we decided to simplify the installer UI, especially when it came to disk partitioning. This has a couple of simple options:

- Take over complete hard disk – Will delete the existing schema, create a partition schema based on a series of space/RAM calculations. Basically implementing a Root/Home/Swap schema.
- Alongside – Will resize the available space and create a schema as above.
- Advanced – Will allow you to repartition the disk however you see fit.

The core code has or is currently in the processes of rationalisation to make it easier for other developers to pick up.

There is still an option to backup all users and groups complete with Home folders to USB disk if you do choose to take over the entire drive. If this option is chosen then data is copied back from the USB disk into the appropriate home folders at the end of the installation process. It is hoped that this will help those that didn’t have /HOME on a separate partition to move over to Aurora without losing data. The USB disk needs to be at least the size of everything under /HOME. As passwords are not copied, user accounts copied from a previous version have the password reset to “aurora” and the password change flag set. Users will need to change the password at first logon.

If you do fancy lending a code hand then you can grab the latest version from subversion and hack away. Code is in Vala and project managed with Anjuta. There’s a couple of README files that list all the dev libraries you need. If you do pick up some development then please let me know what you’re working on to prevent duplication of effort.

Based on the time spent on this rewrite so far I estimate that there is around 5 weeks of development left before a test release will be available.

I’ve been posting screenshots on Twitter (@preobrazhensky), I’ll post some on this blog as and when things get finished.

Ok, just an update on the installer. Gtk2 -> Gtk3 is going a bit slower than I imagined. It seems there’s a lot of API changes and very little in the way of migration docs so it’s a bit of trial and error at the moment. Moving along nonetheless.

Paul is still working on the themes and packages required to implement a clean version of systemd and migrate as many sysv init scripts as possible to give the best boot times.

We still need devs (vala or C), we need plymouth designers and package maintainers… Anyone, anyone, anyone? Bueller? Put your hand up if you want to give us a hand…

More updates soon, soaking up the alcohol in Moscow till Jan

Merry christmas to you all!

So we have a busy couple and months and things are starting to ramp back up at Aurora HQ – We want to make sure you are all kept up to date with current progress…. only issue has been keeping the blog up to date!! Hence the Plan for new and improved simple news updates

We know not everyone uses Twitter so this week I’ve added some further features to the blog

1. Auto Post to Facebook – all our likes on Facebook ( http://facebook.com/getaurora ) can now get updates from the blog straight in their feed.

2. Auto Post to Twitter – Auto post of Short link URLs for new updates to our twitter account @getaurora

3. Auto Tweet to Post – Tweets made from the @getaurora account will appear as a mini Blog update for those not using either service.

Next Step is to try integrate the updates here into the Google Plus page I’ve recently setup but no content is on there yet!

Main priorities now are to get an Alpha release out to get the installer tested while we finish working on the DE experience and to make sure you all know about it!
