Welcome to a new issue of "This Week in KDE Apps"! Every week we cover as much as possible of what's happening in the world of KDE apps.

This week, we are continuing to polish our applications for the KDE Gear 24.12.0 release, but already starting the work for the 25.04 release happening next year. We also made the first release of OptiImage, an image size optimizer.

Meanwhile, as part of the 2024 end-of-year fundraiser, you can "Adopt an App" in a symbolic effort to support your favorite KDE app. This week, we are particularly grateful to Yogesh Girikumar, Luca Weiss and 1peter10 for supporting Itinerary; Tobias Junghans and Curtis for Konsole; Daniel Bagge and Xavier Guillot for Filelight; F., Christian Terboven, Kevin Krammer and Sean M. for the Kontact suite; Tanguy Fardet, dabe, lengau and Joshua Strobl for NeoChat; Pablo Rauzy for KWrite; PJ. for LabPlot; Dominik Barth for Kasts; Kevin Krammer for Ruqola; Florent Tassy, elbekai and retrokestrel for Gwenview; MathiusD and Dadanaut for Elisa, Andreas Kilgus and @rph.space for Konqueror; trainden@lemmy.blahaj.zone for KRDC; Marco Rebhan and Travis McCoy for Ark; and domportera for Krfb.

Getting back to all that's new in the KDE App scene, let's dig in!

Get Involved

The KDE organization has become important in the world, and your time and contributions have helped us get there. As we grow, we're going to need your support for KDE to become sustainable.

You can help KDE by becoming an active community member and getting involved. Each contributor makes a huge difference in KDE — you are not a number or a cog in a machine! You don’t have to be a programmer either. There are many things you can do: you can help hunt and confirm bugs, even maybe solve them; contribute designs for wallpapers, web pages, icons and app interfaces; translate messages and menu items into your own language; promote KDE in your local community; and a ton more things.

You can also help us by donating. Any monetary contribution, however small, will help us cover operational costs, salaries, travel expenses for contributors and in general just keep KDE bringing Free Software to the world.

To get your application mentioned here, please ping us in invent or in Matrix.

Tracking library dependencies work in Debian to resolve from symbols usage to a library and add this to the list of dependencies. That is working for years now. The KDE community nowadays create more and more QML based applications. Unfortunately QML is a interpreted language, this means missing QML dependencies will only be an issue at runtime.

To fix this I created dh_qmldeps, that searches for QML dependencies at build time and will fail if it can't resolve the QML dependency.

Me didn't create an own QML interpreter, just using qmlimportscanner behind the scenes and process the output further to resolve the QML modules to Debian packages.

The workflow is like follows:

The package compiles normally and split to the binary packages. Than dh_qmldeps scans through the package content to find QML content ( .qml files, or qmldirfor QML modules). All founded files will be scanned by qmlimportscanner, the output is a list of depended QML modules. As QML modules have a standardized file path, we can ask the Debian system, which packages ship this file path. We end up with a list of Debian packages in the variable ${qml6:Depends}. This variable can be attached to the list of dependencies of the scanned package. A maintainer can also lower some dependencies to Recommends or Suggest, if needed.

You can find the source code on salsa and usage documentation you can find on https://qt-kde-team.pages.debian.net/dh_qmldeps.html.

The last weeks I now enabled dh_qmldeps for newly every package, that creates a QML6 module package. So the first bugs are solved and it should be usable for more packages.

By scanning with qmlimportscanner trough all code, I found several non-existing QML modules:

• import QtQuick3DPrivate qt6-multimedia - no Private QML module QTBUG-131753.
• import QtQuickPrivate qt6-graphs - no Private QML module QTBUG-131754.
• import QtQuickTimeline qt6-quicktimeline - the correct QML name is QtQuick.Timeline QTBUG-131755.
• import QtQuickControls2 qt6-webengine - looks like a porting bug as the QML6 modules name is QtQuick.Controls QTBUG-131756.
• import QtGraphicalEffects kquickimageeditor - the correct name is for QML6 is qt5compat.graphicaleffects, properly as it is an example nobody checks it kquickimageeditor!7.

YEAH - the first milestone is reached. We are able to simply handle QML modules.

But QML applications there is still room for improvement. In apps the QML files are inside the executable. Additionally applications create internal QML modules, that are shipped directly in the same executable. I still search for a good way to analyse an executable to get a list of internal QML modules and a list of included QML files. Any ideas are welcomed :)

As workaround dh_qmldeps scans currently all QML files inside the application source code.

The Fedora KDE SIG is pleased to announce that KDE Gear 24.12 RC (24.11.90) is available on Fedora 41 via our @kdesig/kde-beta COPR repository

Enjoy!

Kirigami Addons is a collection of additional components for Kirigami applications. This release brings mostly improvements to the FormCard module.

AboutPage

The about page provided by Kirigami Addons received many improvements. Joshua added icons to all the buttons.

I worked on the component section, which now contains more information about the default components as well as the underlying platform and now has a button to copy all this information to the clipboard. This is super helpful, when writing a bug report. There were also some small bug fixes with, for example, the license dialog being correctly sized.

RadioSelector

A new component is the RadioSelector, which is a simple component that allows one to choose an option between two or more choices in a horizontal layout. This is not a new component as it has already been used in Itinerary and Marknote for a long time.

There is also a FormCard version of this, called FormRadioSelectorDelegate.

FormPlaceholderMessageDelegate

Another new component is FormPlaceholderMessageDelegate, which is basically a Kirigami.PlaceholderMessage, but instead of putting it in a ListView, this one is to be put inside a FormCard.

Other

Volker fixed the Android integration of the date picker. He also added support for static builds (required for iOS and probably hopeful for other platforms).

Claudio fixed various issues with the DatePicker.

Joshua made the caption used in AlbumMaximizeComponent selectable with the mouse. He also fixed the separator for the IndicatorItemDelegate which only appeared after the first item.

I added icon support to FormSwitchDelegate, which is similar to what we already have in FormRadioDelegate and FormCheckDelegate.

Packager Section

Kirigami Addons 1.6.0 was tagged but the tarball are not yet available. I will update this post once it is available.

The first release of OptiImage is finally out! OptiImage is a useful image compressor that supports PNG, JPEG, WebP and SVG file types. It doesn’t do the compression itself but uses various tools like oxipng to do the compression.

Thanks to Mathis Brüchert for his work on the icon and to Soumyadeep Ghosh for a bunch of bug fixes and pushing me to do the release.

Packager Section

OptiImage 1.0.0 was tagged but the tarball are not yet available. I will update this post once it is available.

Let’s go for my web review for the week 2024-48.

Self-Hosting Isn’t a Solution; It’s A Patch

Definitely this. Sure we should seek for decentralization, but this is not going to happen or be effective without regulation. Ensuring privacy is a legislative and political problem as much as a technical one.

How decentralized is Bluesky really?

A long and comprehensive analysis of Bluesky. Also brings interesting critiques about both Bluesky and the Fediverse. Clearly Bluesky as of today is not effectively decentralized and shouldn’t be considered as such.

Reply on Bluesky and Decentralization

Tags: tech, social-media, bluesky, fediverse, decentralized

The debate about how BlueSky and decentralisation or federation continues. It’s nice to see how civilized the people involved are. This is how we can make progress.

Naming things

Tags: tech, programming, design, craftsmanship

This is a good point. Idiosyncrasies are not necessarily a bad thing for naming things. Natural languages are fickle friends, you might need to rely to specific metaphors in order to disambiguate.

Another rebuttal of Clean Code. Most of it makes sense if not overdone. There’s the usual confusion around the “unit tests” term though, so take that section with a pinch of salt.

Did you know about a small but very useful feature from KDE?

Open krunner via Alt+Space and type qw:KDE to search Qwant for KDE:

Pressing Enter will open up your browser with the specified KDE search on Qwant!

There are a lot of other Web Search Keywords like:

Wikipedia:

Invent:

Translate from English to German on dict.cc

You can find all of them by opening Web Search Keywords on krunner:

Extra: Create your own!

I use often a Fedora tool called COPR, so let’s use it as an example to create our own web search keyword.

Do your search in the webpage:

And now the important part you need:

Now back to the Web Search Keyword settings:

Fill in the data needed taking care of the placeholder for our input!:

Now we have our own Web Search Keyword:

NOTE: for some reason I had to click on Apply and OK until all the different setting windows were closed before the new custom Web Search Keyword worked

And the result:

I hope it’s useful to somebody!

In order to prepare for the Akademy I started some days before to give my Librem 5 ( an Open Hardware Phone) another try and ended up with a non starting Plasma 6. Actually this issue was known already, but hasn't been addressed. In the end I reached the Akademy with my Librem 5 having phosh installed (which is Gnome based), in order to have something working.

I met Bushan and Bart who took care and the issue was fixed two days later I could finally install Plasma 6 on it. The last time I tested my Librem 5 with Plasma 5 it felt sluggish and not well working. But this time I was impressed how well the system reacts. Sure there are some things here and there, but in the bigger picture it is quite useable. One annoying issue is that the camera is only working with one app and the other issue is the battery capacity, you have to charge it once a day. Because of missing a QR reader that can use the camera, getting data to the phone was quite challenging. Unfortunately the conference Wifi separated the devices and I couldn't use KDE Connect to transfer data. In the end the only way to import data was taking five photos from the QR Code to import my D-Ticket to Itinerary.

With a device with Plasma Mobile, it directly was used for a experiment: How well does Dolphin works on a Plasma Mobile device. Together with Felix Ernst we tried it out and were quite impressed, that Dolphin does work very well on Plasma Mobile, after some simple modifications on the UI. That resulted in a patch to add a mobile UI for Dolphin !826.

With more time to play with my Librem 5 I also found an bug in KWeather, that is missing a Refresh option, when used in a Plasma Mobile environment #493656.

Akademy is a good place to identify and solve some issues. It is always like that, you chat with someone and they can tell you who to ask to answer the concrete question and in the end you can solve things, that seems unsolvable in the beginning.

There was also time to look into the travelling app Itinerary. A lot people are faced with a lot of real world issues, when not in their home town. Itinerary is the best traveling apps I know about. It can import nearly every ticket you have and can get location information from restaurant websites and allow routing to that place. It does add many useful information, while traveling like current delays, platform changes, live updates for elevator, weather information at the destination, a station map and all those features with strong focus on privacy.

In detail I found some small things to improve:

• If you search for a bus ride and enter the correct name for the bus stop, it will still add some walk from and to the station. The issue here is that we use different backends and not all backends share the same geo coordinate. That's why Itinerary needs to add some heuristics to delete those paths.

• Instead of displaying just a small station map of one bus stop in the inner city, it showed complete Würzburg inner city, as there is one big park around the inner city (named "Ringpark").

• Würzburg has a quite big bus station but the platform information were missing in the map, so we tweaked the CSS to display the platform. To be sure, that we don't fix only Würzburg, we also looked at Greifswald and Aix-en-Provence if they are following the same name scheme.

I additionally learned that it has a lot of details that helps people who have special needs. That is the reason why Daniel Kraut wants to get Itinerary available for iOS. As spoken out, that Daniel wants to reach this goal, others already started to implement the first steps to build apps for iOS.

This year I was volunteering in helping out at Akademy. For me it was a lot of fun to meet everyone at the infodesk or help the speakers setup the beamer and microphone. It is also a good opportunity to meet many new faces and get in contact with them. I see also room for improvement. As we were quite busy at the Welcome Event to get out the badges to everyone, I couldn't answer the questions from newcomers, as the queue was too long. I propose that some people volunteer to be available for questions from newcomers. Often it is hard for newcomers to get their first contact(s) in a new community. There is a lot of space for improvement to make it easier for newcomers to join. Some ideas in my head are: Make an event for the newcomers to get them some links into the community and show that everyone is friendly. The tables at the BoFs should make a circle, so everyone can see each other. It was also hard for me to understand everyone as they mostly spoken towards the front. And then BoFs are sometimes full of very specific words and if you are not already deep in the topic you are lost. I can see the problem, on the one side BoFs are also the place where the person that knows the topic already wants to get things done. On the other side new comers join BoFs, are overwhelmed by to many new words get frustrated and think, that they are not welcome. Maybe at least everyone should present itself with name and ask new faces, why they joined the BoF to help them joining.

I'm happy, that the food provided for the attendees was very delicious and that I'm not the only one mostly vegetarian with a big amount to be vegan.

At the conference the KDE Eco initiation really caught me, as I see a lot of new possibilities in giving more reasons to switch to an Open Source system. The talk from Natalie was great to see how pupils get excited about Open Source and also help their grandparents to move to a Linux system. As I also will start to work as a teacher, I really got ideas what I can do at school. Together with Joseph and Nicole, we finally started to think about how to drive an exploration on what kind of old hardware is still KDE software running. The ones with the oldest hardware will get an old KDE shirt. For more information see #40.

The conference was very motivating for me, I also had still energy at the evening to do some Debian packaging and finally pushed kweathercore to Debian and started to work on KWeather. Now I'm even more interested in the KDE apps focusing the mobile world, as I now have some hardware that can actually use those apps.

I really enjoyed the workshop how to contribute to Qt by Volker Hilsheimer, especially the way how Volker explained things in a very friendly way, answered every question, sometime postponed some questions but came back to them later. All in all I now have a good overview how Qt is doing development and how I can fix bugs.

The daytrip to Rothenburg ob der Tauber was very interesting for me. It was the first time I visited the village. But in my memory it feels like I know the village already. I grew up with reading a lot of comic albums including the good SiFi comic album series "Yoku Tsuno" created by the Belgian writer Roger Leloup. Yoku Tsuno is an electronics engineer, raised in Japan but now living in Belgium. In "On the edge of life" she helps her friend Ingard, who actually lives in Rothenburg. Leloup invested a lot of time to travel to make the make his drawings as accurate as possible.

In order to not have a hard cut from Akademy to normal life, I had a lunch with Carlos, to discuss KDE Neon and how we can improve the interaction with Debian. In the future this should have less friction and make both communities work together more smoothly. Additionally as I used to develop on KDEPIM with the help of Docker images based on Neon I ask for a meta kf6 dev meta package. That should help to get rid of most hand written lists of dev packages in the Docker file in order to make it more simple for new contributors to start hacking on KDEPIM.

The rest of the day I finally found time to do the normal tourist stuff: Going to the Wine bridge and having a walk to the castle of Würzburg. Unfortunately you hear a lot of car noises up there, but I could finally relaxe in a Japanese designed garden.

Finally at Saturday I started my trip back. The trains towards Eberswalde are broken and I needed to find alternative routing. I got a little bit nervous, as it was the first time I travelled with my Librem 5 and Itinerary only and needed to reach the next train in less than two mins. With the indoor maps provided, I could prepare my run through the train station so I reached successfully my next train.

By the way, also if you only only use KDE software, I would recommend everyone to join Akademy ;)
