What gpk-application looks like with collection support

A collection is a metapackage that can represent a group, where the package mapping is done inside the backend. It is not like a catalog where an external file provides a meta-group. This enables the “group install” and “group remove” functionality people have been requesting since version 0.1.0, without get another abstract group mapping or extra API to support.

I’ve made a few changes in the daemon to properly support this new type, and in the yum backend Tim Lauridsen has added support using the comps group mapping. Mike Langlie has drawn us some great icons, and Anders F Björklund implemented collections for smart, and helped us with the design process. The extra type should be trivial to add to other backends too.

We added the feature in just a few hours of hacking, as everyone was working together. I’m amazed at how people work together so well all over the globe, in different timezones and with different work priorities – thanks guys.

Comments, as always, appreciated

Actually in gnome-packagekit git, but nothing uses it yet…

Test page shipped with PackageKit

It’s actually pretty easy to build a website that wants to install something new or run an application that is already installed.

The actual html you need is something like this:

<object type="application/x-packagekit-plugin" width="500" height="200" class="packagekit-plugin">
<param name="displayname" value="KStars"/>
<param name="packagenames" value="kdeedu kde4edu"/>
<param name="desktopnames" value="kstars"/>
</object>


You can omit displayname and desktopnames if you wish, as PackageKit can query the backend and fill in the blanks. The packagenames are queried until PackageKit finds one that matches on your system.

I’m also thinking about adding the application icon in the box as common applications usually have standard icons that PackageKit already uses for other stuff.

Of course, because this uses PackageKit, it’ll work on any distro. If you want to improve the look of the plugin or add some extra features, jump on the mailing list and give ideas. Feedback welcome.

Of course, this is limited by the distribution guys putting in the effort writing PackageKit backends for their system, packaging it up into packages, and then deploying it in new distributions to hapless users.

So far, we have quite a few distributions shipping PackageKit by default, and there’s every indication that a large majority will be shipping PK by the end of the year. Recently I’ve been very impressed with the work of Sebastian Heinlein integrating PK with APT. It’s been pretty difficult, as he’s been patching (rewriting?) chunks of python-apt so that the PackageKit API can be completed. For SMART, Anders F Bjorklund has also been writing huge chunks of code, which is also great.

You can see how the other distributions are doing here.

I’ve not really thought about the UI for the notification (and traditionally I suck at UI design), and so I welcome advice and comments from you guys. I’ve got this so far:

Slides are here. Thanks

New UI?

Comments, suggestions?

In an ideal world, we could still query a software list while we are updating, but a lot of the backends do not allow that, giving unpredictable results or ‘just‘ corrupting caches.

One of the main feature requests for 0.2.x was to handle multiple packages in one transaction. The API was slightly changed in PackageKit to support this in 0.2.1, and now the client tools like pkcon and gpk-install-package-name all accept more than one package at a time. Yay for the command line.

This left gpk-application, aka “Add/Remove Software” – which was much trickier to do in a sane way. Now, I’m not saying the screenshot below is sane, but it certainly works, and we can improve it in the few weeks before 0.2.2 is released.

Comments welcome.

See here for a sneak preview. There’s also a screenshot of the OpenSuse updater, which is also working with a PackageKit backend now.

Next step, world domination. Seriously, rock on.

So, enough of the geeky. What do you all think of this:

Code about to hit master…
