KDE Applications Versioning

A common problem for many applications contained in the KDE Applications releases are non-incremented version numbers. Often the maintainer forgets to update the version number of the application, like I did it for Kate since the first KF5 based release.

This means: On Bugzilla, I get bugreports that always tell me “Kate 5.0.0″, not very helpful.

KDE Frameworks solves this by automatic setting of the current framework release version in all framework CMakeLists.txt.

For KDE Applications, we have now optional the same concept. For details: visit

In short: If you are to lazy to update your version number yourself or are just fine with using the same version number als the KDE Applications releases, you can add the following three lines to your toplevel CMakeLists.txt:

# KDE Application Version, managed by release script

These variables will then be patched by the release scripts to the “right” version for the current release series.
You can than either just use the MICRO version to suffix your own applications version to differentiate the bugfix releases or like Kate construct your complete version number from the three vars and be done ;=)

I hope this helps to have more consistent and more important meaningful version numbers once again in the applications we bundle. Thanks to all people that made this “magic” happen ;=)

Reception of Plasma Mobile

The yearly KDE conference Akademy is currently being held with lots of interesting talks and workshops. One big thing that was announced yesterday is Plasma Mobile, a free mobile platform.

Plasma Mobile, a Free Mobile Platform

The presentation of Plasma Mobile was quite impressive: A video of using Plasma Mobile on a Nexus 5 showed a nice  visual design, smooth transitions and quite some usable functionality already. This impression was confirmed later when I was playing around with Plasma Mobile on the Nexus 5 myself.

So good job, plasma team!

Plasma Mobile already raised quite some interest in lots of news sites, with lots of user comments (mostly positive), see for instance:

What’s important to note is that the project is still in a very early stage of development, and its target is to be really usable around mid of 2016. As such, there are most certainly stability issues and lots of features missing.

But this also opens opportunities: If you are into mobile platforms, this is the right time to get in contact and contribute! The plasma developers are really nice people and welcome every single contribution, be it in terms of brainstorming ideas (e.g. graphical mockups), code, or organizing developer events. So get in touch now through the Plasma Mobile forums and through the Plasma Contributor Mailing List! Just say hi and ask how to get involved :-)

KF5 & Plasma 5 at work ;=)

In the last months, I didn’t get much time to work on Kate nor KTextEditor. Beside some small bugfixes and cleanups I got nothing commited :/

Guess one of the main issues is, I don’t use the KF5 based version of Kate that much ATM. At home, it is the only editor I use, but I have not much time to hack at home anyway.

Therefore today I installed the same setup on my work machine and will now use the KF5 based Kate for all of my day job, perhaps that motivates me more to take a look at the issues the Qt5/KF5 port still has.
(And I will work in a KDE Plasma 5 session with most stuff KF5 based now, including all important stuff like the nice Konsole ;=)

First update: The Get It page got an update to show how to install KF5 based Kate/KWrite from kate.git on openSUSE 13.2 😉 Feel free to send in the needed hints for other distros (to
The installation hints for KDE 4.x based Kate got moved to Get It – KDE 4.x, to keep them intact!

Add yourself to the relicense checker script

From the KDE relicensing page:

A couple of KDE dependent projects or even libraries have moved or are going to move to GPLv3.

Unfortunately, GPL v3 is incompatible with GPL v2. This means that it is not possible to create a project linking GPL v2 and v3 code together. There is no problem for projects which are licensed GPLv2+ (version 2 or above).

A few parts of KDE are currently licensed as GPLv2 only. So far we have no reason to believe that this was something other than an oversight. However, we still need to validate with the individual copyright holders that a relicense to GPLv2+ or GPLv2+v3 is okay with them.

Therefore, in an effort we’re trying to identify the contributors that have contributed under the terms of GPLv2 and where the “+” part was not explicitly mentioned. If we know that all contributors agreed to a relicense, we can go ahead and flip the license of the individual source file.

Short story: If you have not done so yet, please add yourself to the kde file!
