Another busy month, another round of great features being worked on. March featured our Plasma 5.6 release which had lots of last minute (aka bug fixing) focus. We had our sprint at CERN. But of course also new code was added.
One of the features on my TODO list for Plasma 5.7 is the ASCII art output rendering. Mplayer supports that and while that is nice, it’s not really a good solution. It would be way more convenient to have the complete workspace rendered through ASCII art to not have to implement this feature in every application.
Unfortunately it’s only supported by our QPainter based compositor. Thus to run it, you need to make sure to use KWIN_COMPOSE=Q to pick the QPainter backend (yeah we should improve that to have a better automatic selection). This is the first platform which support both nested and full mode. Thus you can run with –ascii in your normal X session which will open a window, just like our nested X11 platform plugin. The rendering is done through the great caca library.
What I’m personally impressed about is how small this new platform plugin is. Less than 400 lines of code, great job by libcaca. But it also shows how easy it is to get KWin on a new platform.
This article is an April Fool. For an explanation please see the update.
Some time ago Ken introduced the conecept of dynamic window decorations (DWD) and during the last Plasma sprint there was already some work on experimenting with an implementation. DWD are extremely promising to enhance the user experience by morphing the application and window manager scope together.
The basic concept of DWD is to get content of the application inside the scope of the window manager. But what works one way works also the other way: we can enhance the user experience by providing additional information relevant for the window inside the window decoration.
An example for this could be a volume applet for music and audio players. But of course it doesn’t stop there, today is all about the user content and integrating the web. For web browsers we can integrate a global “Like It on Facebook” button. And by analyzing the user behavior we can provide even more help. We can notice if you struggle using Krita and provide a link to where to get a better drawing tablet.
If you use digiKam you might be interested in some books about photogrophy. We know which music you listen to on Amarok and show you that the new album of your favorite music group just got released. Not every application integrates stores in a proper way. This is a shame as it does not provide the best possible user experience and KWin as a window manager can help there to add missing store functionality where it is needed.
Of course this also allows to show you better alternatives. If we see that you struggle with wine emulated applications we can provide the Linux alternative. We can show that new updates are available for your currently used application. If you use sub-par free software applications we can show you were to get a proper (slightly more expensive) application.
But DWD are not the only place where KWin can help to increase the user experience by offering useful content. We always went a great way to make the desktop more useable by for example allowing to click on a splash screen to hide it. I think we can all agree that splash screens are something really useless: look at a stupid window for a few seconds and having to wait till it hides again. Meh.
We can do better: we know which application starts and what it is used for. And as a compositor we can exchange the content. Wouldn’t it be way more awesome to show a short video giving you advice where to buy the latest tips on C++11 book when launching kdevelop?
And there is so much more room to integrate useful content. When starting a video player we can overlay the window with a nice trailer of the latest movie (of course that will be skipable after 5 sec). This is a feature which might also be handy in Present Windows and Alt+Tab. Of course such videos would be perfectly localized as we know your geolocation and we would take great efforts to only offer trailers which might interest you: after all we have baloo to scan your video data and can also look at your Facebook profile. Now trailers are only one part, of course also other areas could be covered. If you have many pictures of cars you might be rather interested in spots about the latest car of your favorite brand instead of move trailers. Of course we will make it possible to configure which areas you are interested in. As we all know KDE is all about configurability.
