Chat Changes, Editor Enhancements and Audio Advancements

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's changes and improvements cover a wide range of applications, from audio apps (including the classic Amarok, which is making a comeback) to Kate getting improvements to its integrated Git features.

In between, you have everything from new functionalities for note-taking utilities and media players, to upgrades in financial software and mobile apps.

Let's dig in!

Amarok Rediscover your music

Tuomas Nurmi worked on making the codebase Qt6-compatible. (Tuomas Nurmi, Link)

Ark Archiving Tool

Jin Liu disabled the "Compress to tar.gz/zip" service menu items in read-only directories. (Jin Liu, 24.12.0. Link)

Dolphin Manage your files

You can now sort your videos by duration. (Somsubhra Bairi, 24.12.0. Link)

Eren Karakas added more standard actions (Sort By, View Mode, Cut and Copy) to the context menu in the trash view. (Eren Karakas, 24.12.0. Link)

Elisa Play local music and listen to online radio

Elisa now supports loading lyrics from .lrc files sitting alongside the song files. (Gary Wang, 24.12.0. Link)

Manuel Roth fixed the bug in which the metadata for webradio http streams was not getting displayed. (Manuel Roth, 24.12.0. Link)

Haruna Media player

You now have the option to open videos in full screen mode. (Rikesh Patel, Link)

KDE Itinerary Digital travel assistant

Volker Krause was at the OSM Hack Weekend last week and worked on the support of MOTIS v2 API support in the public transport client library used by KDE Itinerary. He also added a map view of an entire trip to Itinerary and the KPublicTransport demo application.

Read more on his blog!

Kate Advanced text editor

In large repos, a git status update can be slow. The least we can do for the user is show that something is happening. Hence, now, if the git status is being refreshed you will see the refresh button become unclickable and start spinning. (Waqar Ahmed, 24.12.0. Link)

In the project tree view, files will now show their status in git. The status is shown minimally, i.e. via a small circle displayed in front of the file name. If the file has been modified, the circle is red; if the file is staged, it's green. (Waqar Ahmed, 24.12.0. Link)

We simplified the git panel by hiding the project combobox. The git panel will now show the status of the currently opened project. (Waqar Ahmed, 24.12.0. Link)

We fixed the SQL plugin's SQL export being randomly ordered. (Waqar Ahmed, 24.08.3. Link)

Clock Keep time and set alarms

KClock's timer now shows the remaining time instead of the elapsed time. (Zhangzhi Hu, 24.12.0. Link)

KMix Sound Mixer

We fixed the Audio Setup button, which didn't open the System Settings Audio page correctly. (Sergio Basto, 24.12.0. Link)

KMyMoney Personal finance manager based on double-entry bookkeeping

It's once again possible to download stock quotes from yahoo.com after they changed their output format. (Ralf Habacker, Link)

Reports can now be exported as PDF and XML. (Ralf Habacker, KMyMoney 5.2.0. Link 1, link 2)

Photos Image Gallery

We improved the design of the properties panel. (Carl Schwan, 24.12.0. Link)

Kleopatra Certificate manager and cryptography app

The name of the "KWatchGnuPG" utility provided by Kleopatra has been updated to "GnuPG Log Viewer" (Carl Schwan, 24.12.0. Link) and we gave it a new logo.

KleverNotes Take and manage your notes

KleverNotes' painting mode has been completely rewritten. It is now possible to add circles, rectangles, labels, and to choose the stroke size. The UI also uses a new floating toolbar. (Louis Schul, 1.2.0. Link)

We improved the animation when switching pages. (Luis Schul, 1.2.0. Link)

The note preview in the appearance settings was simplified to only show the important parts. (Luis Schul, 1.2.0. Link)

KMail A feature-rich email application

Fix a crash in the Exchange Web Services (EWS) backend. (Louis Moureaux, 24.08.3. Link)

KRDC Connect with RDP or VNC to another computer

We fixed sharing folders. (Fabio Bas, 24.08.3. Link)

Merkuro Calendar Manage your tasks and events with speed and ease

Claudio Cambra fixed adding and creating sub-todos (Claudio Cambra, 24.08.3. Link and Link)) and a bug that made clicking on the month view unreliable. (Claudio Cambra, 24.08.3, Link).

We also added back the maps showing the location of individual events. This was disabled during the Qt6 migration and never enabled back afterwards. (Claudio Cambra, 24.08.3, Link)

NeoChat Chat on Matrix

Support for libQuotient 0.9 has been backported to NeoChat 24.08. This brings, among other things, cross-signing support and support for the Matrix 1.12 API, including most importantly content repo functionality switching to authenticated media. (James Graham, 24.08.0, Link)

Okular View and annotate documents

Albert Astals fixed switching between pages in the single-page mode when using a mouse with a "high resolution" scroll wheel. (Albert Astals Cid, 24.12.0. Link)

You can now use any image type as a signature background. (Sune Vuorela, 24.12.0. Link)

We removed the last CHM support mention in Okular and on the website. CHM support was dropped when transitioning to the Qt6 version. (Albert Astals Cid, 24.12.0. Link 1, link 2)

Zanshin To Do Management Application

Fixed an issue where projects would be displayed twice when toggling on and off their data source. (David Faure, 24.08.3. Link)

And all this too...

Justin Zobel fixed various appstream files to use the new way of declaring the developer's name. (Justin Zobel, KRuler, Gwenview, KEuroCalc, ...)

We ported various projects to use declarative QML declaration for better maintainance and performance (Carl Schwan, Koko, Francis, Kalk).

Last weekend I attended the bi-annual OSM Hack Weekend in Karlsruhe again, organized by Geofabrik and this time hosted at a nearby university building due to the large number of participants.

Transitous

My main focus has been getting the public transport client library used by KDE Itinerary ready for MOTIS v2, as Transitous, our community-run public transport routing service, will switch to that in the not too distant future.

One big new feature in MOTIS v2 is support for GTFS shapes. That is, getting detailed paths for public transport sections, beyond just positions of intermediate stops, which allows for a much more useful map display for example.

Even more importantly, MOTIS now also provides detailed multi-floor paths for transfers or other parts of a trip where you have to move yourself (walking, biking, etc). This is all based on OSM data and thus matches perfectly to the map data, but since practically no other backend provides this level of detail it also required a few changes in our data model and API.

Besides the new MOTIS API being much more intuitive than the previous one having had Felix from the MOTIS team around (even if just online) who instantly implemented all suggested improvements in the server made this super productive.

If your region isn’t covered by Transitous yet, check out the contributor documentation on how to change that.

Itinerary

For debugging parsing of paths provided by MOTIS I added a map view to the KPublicTransport demo app. That ended up getting close to what we’d need for a map view of an entire trip in Itinerary, so we also have that now. It’s not where I’d like it yet e.g. regarding interactivity and the look of bi-directional paths it’s a good start.

A full trip map view was also one of the feature requests I got from other participants. Another suggestions that came up and that meanwhile has been implemented is pre-filling the stop location history with all locations involved in the current trip, which is quite helpful during trip planning.

Indoor Routing

Following a discussion on detailed mapping of hedges in outdoor mazes I learned there’s an OSM wiki page on that subject, which also lists a bunch of examples.

While I don’t really have any particular interest in outdoor mazes and/or fancy hedge art, these things just ask for being used as a test case for our indoor router.

You can help!

Hack weekends how this is called in the OSM community or sprints as this is known in the KDE community are immensely valuable and productive. There’s a great deal of knowledge transfer happening, and they are a big motivational boost.

However, physical meetings incur costs, and that’s where your donations help! KDE e.V. and local OSM chapters like the FOSSGIS e.V. support these activities.

We continued fixing bugs and making UI improvements this week. You’ll notice a good many of them are about screens somehow! Ah, screens, the magical windows to our computers. They are amazing… and they suck. So many graphics driver bugs and hardware quirks to work around, so many edge cases to handle… and so that was a large part of what we spent doing for you, dear reader! Because getting all this screen stuff right has a massive impact on quality.

And of course there was a lot of other work too!

Notable UI Improvements

There’s a new behavior when dragging things out of a window that’s not the top one in the stacking order: the window with the dragged content remains where it is during the drag, instead of immediately jumping to the front (Xaver Hugl, Plasma 6.3.0. Link)

Kickoff, Kicker, and other launcher menus now have a “Help” category, and the Help Center app appears there instead of among other top-level categories (me: Nate Graham, Plasma 6.3 and KHelpCenter 24.12. Link 1, link 2, and link 3):

Added a touch-friendly UI for the clipboard widget that appears only when in touch mode (Fushan Wen, Plasma 6.3.0. Link)

Fixed a case where some system components’ default shortcuts all wanted to use Meta+0 and interfered with one another. Now they all use different shortcuts:

• “Zoom to Actual Size” remains Meta+0
• “Manually Invoke Action on Current Clipboard” and “Activate Task Manager Entry 10” no longer have a default shortcut set

(Zhangzhi Hu, Plasma 6.3.0. Link)

WireGuard VPNs are now considered VPNs by the Networks widget, and labeled and grouped accordingly (Ivan Tkachenko, Plasma 6.3.0. Link)

Multi-instance or multi-process Flatpak apps are now grouped together and shown as only one app on System Monitor’s Applications page (Arjen Hiemstra, Plasma 6.3.0. Link):

SDDM themes that are actually just symlinks to other themes are now filtered out of the relevant page in System Settings (Bruno Ivan, Plasma 6.3.0. Link)

Capped the maximum width of the Bluetooth file transfer error dialog so it can’t be ridiculously wide (Zhangzhi Hu, Plasma 6.3.0. Link)

Added Breeze icons for Typst files (MV Puccino, Frameworks 6.8. Link)

A bunch of symbolic Breeze icons that were inappropriately symbolic-but-colorful are now monochrome to better match all the other monochrome symbolic icons (me: Nate Graham, Frameworks 6.8. Link)

Notable Bug Fixes

Fixed a bug that could cause KWin to freeze when plugging in a Valve Index VR headset when there are no other screens enabled (Xaver Hugl, Plasma 6.2.2. Link)

Fixed a case where Plasma could crash when interacting with connected storage devices in certain ways (Fushan Wen, Plasma 6.2.2. Link)

Fixed a bug that would cause the positions of recently-renamed desktop files to not be saved to the config file correctly (Akseli Lahtinen, Plasma 6.2.2. Link). And on this subject, we’re currently deep into the process of fixing a related bug that causes icons to get scrambled when some (but not all) screens are turned off. Not for this week, but maybe next week!

Fixed a set of regressions that caused System Settings’ main window to not remember its size correctly (Akseli Lahtinen, Plasma 6.2.2 with Frameworks 6.8. Link)

Fixed a recent regression that made certain styles of user avatar image not get applied properly on System Settings’ Users page (Harald Sitter, Plasma 6.2.3. Link)

Spectacle no longer fails to save MP4-formatted screen recordings some of the time (Arjen Hiemstra, Plasma 6.2.3. Link)

You can now do a rectangular region screencast on any screen in a multi-screen setup, not just the left-most one (David Redondo, Plasma 6.2.3. Link)

The “Maximum time before updates” setting for grid-style System Monitor widgets now works (Arjen Hiemstra, Plasma 6.2.3. Link)

Worked around a quirk of certain HDR-capable screens screens that caused them to leave HDR move whenever any other display settings were changes (Xaver Hugl, Plasma 6.2.3. Link)

The “Forget all” menu item of Task Manager Task context menus now succeeds at forgetting abstract resources like URLs (Jin Liu, Plasma 6.2.3. Link)

Made it more reliable to save custom names given to audio devices (Harald Sitter, Plasma 6.2.3. Link)

Fixed a case where the ksystemstats background service that provides information to System Monitor and its widgets’ could crash due to a recent change in Qt (Arjen Hiemstra, Plasma 6.3.0. Link)

Fixed a case where Plasma and other KDE apps could crash when ejecting a CD (Nicolas Fella, Frameworks 6.8. Link)

When your user account is slightly misconfigured and does not define a templates directory, the “Create New” menu does no longer weirdly populates itself with the entire contents of your home folder (Benjamin Gonzalez, Frameworks 6.8. Link)

Fixed an issue that could cause the setting to govern notification sound level to not appear as expected (Harald Sitter, Pulseaudio-Qt 1.6.1. Link)

Fixed a bug that could cause the pointer’s target to get sort of stuck after dragging things until after the first click following the completion of the drag. This was commonly seen when re-arranging Task Manager entries: if you failed to click once after dragging an app, the next drag would target the preciously-dragged app instead of the one you wanted (David Edmundson, Qt 6.8.1. Link)

Other bug information of note:

• 5 Very high priority Plasma bug (up from 4 last week). Current list of bugs
• 35 15-minute Plasma bugs (up from 33 last week). Current list of bugs
• 129 KDE bugs of all kinds fixed over the last week. Full list of bugs

Performance & Technical

Improved the reliability of the “remember for next time” feature in the screen recording source chooser window (David Redondo, Plasma 6.3. Link)

Reduces a source of slowness in the Task Manager widget when faced with windows that have hundreds or thousands of characters in their titles (Jin Liu, Plasma 6.2.3. Link)

The Night Light feature now tints the screen in a colorimetrically correct way when not using ICC profiles (Xaver Hugl, Plasma 6.3.0. Link)

It’s now possible to use Plasma scripting to change panels’ opacity levels or what screen they appear on (Heitor Augusto Lopes Nunes and Devin Lin, Plasma 6.3.0. Link 1 and link 2)

Tags: cognition, neuroscience, language, logic, knowledge, research

Very interesting research. Looks like we’re slowly moving away from the “language and thinking are intertwined” hypothesis. This is probably the last straw for Chomsky’s theory of language. It served us well but neuroscience points that it’s time to leave it behind.

Reliable Reasoning Beyond Natural Language

Tags: tech, ai, machine-learning, gpt, logic, research

Now this is an interesting paper. Neurosymbolic approaches are starting to go somewhere now. This is definitely helped by the NLP abilities of LLMs (which should be used only for that). The natural language to Prolog idea makes sense, now it needs to be more reliable. I’d be curious to know how many times the multiple-try path is exercised (the paper doesn’t quite focus on that). More research is required obviously.

Framework overload: when convenience dulls innovation in software development

Tags: tech, framework, complexity, knowledge, learning, debugging, craftsmanship

I very much agree with this. The relationship between developers and their frameworks is rarely healthy. I think the author misses an important advice though: read the code of your frameworks. When stuck invest sometime stepping into the frameworks with the debugger. Developers too often treat those as a black box.

Bye for now!

This week, we realized that there are a few things we need to do to button-down our use of colors in a way that makes sense, not just for designers but also for developers.

As we find inspiration on what others are doing, we will make a couple of changes in the design system when it comes to colors.

1. Select UI colors using HCT color methodology.
2. Adopt a similar variable/token naming strategy as Material Design

HCT (hue, chroma, tone) Method

As suggested by team members, the HCT color selection methodology has a few advantages:

1. Accessibility
   • Standard calculation method for color selection rather than by doing manual contrast calculations. This allows for all selected colors to be separated and distinct-enough from each other that users can see color differences in their applications.
2. Perceptual accuracy
   • HCT allows for seeing colors more accurately at a perceptual level.
3. Consistent lightness and colorfulness
   • Consistent lightness and colorfulness across hues. 
4. Precise color and tonal accuracy
   • More precise color and tonal accuracy, especially in dark shadows and richly-saturated colors. 
5. Higher dynamic range and wider color gamut
   • Provides a wider color gamut and higher dynamic range than typical camera targets.

In our team, we have 3 people currently working on this. Not only are we selecting colors, but also creating a color-use system that all users can understand.

Building logic use into the colors allows for less dependence on people but something we can document and anyone looking at it would be able to understand regardless of their specialty.

Tokens

A few of the questions we had as a team while producing the design system were, how can we make it so that developers and designers understand all the pieces used in the design system, but at a development level?

One of the things that applications such as Figma and PenPot allow is for designers to define the names of each of the elements used in a design. We create variables names for stuff like fonts and colors. However, while that’s helpful, we also have to have logic behind the naming so that our developer friends are not confused by the use of variable names in the design system.

For this purpose, design system creators often use a token system that ensures naming between the design system and development is consistent, predictable, and useful.

Material design has a robust naming idea around tokens. It works a little like this:

The types of tokens are:

1. Reference tokens
   All available tokens with associated values
   
2. System tokens
   Decisions and roles that give the design system its character, from color and typography, to elevation and shape
   
3. Component tokens
   The design attributes assigned to elements in a component, such as the color of a button icon

We consulted with the team members and it seems like a good strategy. Right now, we don’t have any of the reference or system tokens but we use component tokens in some capacities. The idea is to create and organize the naming conventions around the token ideas from Material. We may still decide to change some of the naming conventions but keep the general idea.

Note that we don’t have the intention of replacing current tokens. The process would be to add new ones that developers would begin using over time while keeping the ones we already have.

What this means for us in the design system, is that we will change our design variables to reflect this organization and when communicating the changes to the dev team, we will provide tables showing all the variables/tokens used. It will also contain which elements of the design system are included in a reference, system, or component token.

If you would like to participate of this effort, you’re welcome to join us here:

I’m going to change up the Calamares release process a little. It’s been slow going as a community-maintained project – which isn’t to say that that is a bad thing. Just slow. I’ve decided to make releases marginally more predictable than “when [ade] has a relaxed kind of Tuesday” and have marked a couple of issues with the Calamares 3.3 milestone. When the milestone is empty again, then there will be a release. After the next release, I’ll put a couple more issues on the milestone, and the recipe can be repeated.

Many years ago I was involved in software-quality research – the SQO-OSS project and things like that. That work begat the code-quality checking scripts that we in the KDE community called “the EBN”, or EnglishBreakfastNetwork. I was a tea-drinker then. The EBN stuff has been surpassed by Klazy and many other software-quality-checking tools. But the EBN domain carries on. Although I haven’t got anything to put on it I just renewed the domain again for two years – just in case.

All but one of KDE's Google Summer of Code (GSoC) projects are complete. This post will summarize the completed project outcomes. GSoC is a program where people who are students or are new to Free and Open Source software make programming contributions to an open source project.

Projects

Arianna

• Port Arianna to Foliate-js: Ajay Chauhan worked on porting Arianna from epub.js to use Foliate-js. The work will hopefully be merged soon.

Frameworks

Python bindings for KDE Frameworks:

Manuel Alcaraz Zambrano, implemented Python bindings for KWidgetAddons, KUnitConversion, KCoreAddons, KGuiAddons, KI18n, KNotifications, and KXmlGUI. This was done using Shiboken. In addition, Manuel wrote a tutorial on how to generate Python bindings using Shiboken. The complicated set of merge requests are still being reviewed, and Manuel continues to interact with the KDE community.

KDE Connect

Update SSHD library in KDE Connect Android app

The main aim of ShellWen Chen's project was to update Apache Mina SSHD from 0.14.0 to 2.12.1. The older version has a few listed vulnerabilities. The newer library required additional code to enable it to work on older Android phones, upto Android API 21.

KDE Games

Implementing a computerized opponent for the Mancala variant Bohnenspiel:

João Gouveia created Mankala engine, a library to enable easy creation of Mancala games. The engine contains implementations for two Mancala games, Bohnenspiel and Oware. Both games contain computerized opponents, João also started on a QtQuick graphical user interface. The games are functional, but additional investigation on computerized opponents may help improve their effectiveness.

Kdenlive

Improved subtitling support for Kdenlive:

Kdenlive has gotten improved subtitling support. Chengkun Chen added support for using the Advanced SubStation (ASS) file format and for converting SubRip files to ASS files. To support this format, Chengkun Chen also made subtitling editor improvements. The work has been merged in the main repository. Documentation has been written, and will hopefully be merged soon.

Krita

Creating Pixel Perfect Tool for Krita:

Ken Lo worked on implementing Pixel Perfect lines in Krita. As explained by Ricky Han, such algorithms remove corner pixels from L shaped blocks and ensure the thinnest possible line is 1 pixel wide. Implementing such algorithms well is of use not only in Krita, but also in rendering web graphics where user screen resolutions can vary significantly. The algorithm was implemented to work in close to real time while lines are drawn, rather than as a post processing step. Ken Lo's work has been merged into Krita.

Labplot

Improve Python Interoperability with LabPlot

Israel Galadima worked on improving Python support in LabPlot. Shiboken was used for this. It is now possible to call some of LabPlot functions from Python and integrate these into other applications.

3D Visualization for LabPlot

Kuntal Bar added 3D graphing abilities to LabPlot. This was done using QtGraphs. The work has yet to be merged, but there are many nice examples of 3D plots, for bar charts, scatter and surface plots.

Snaps

Improving Snap Ecosystem in KDE

Snaps are self contained linux application packging formats. Soumyadeep Ghosh worked on improving the tooling necessary to make KDE applications easily available in the Snap Store. In addition, Soumyadeep improved packaging of a number of KDE Snap packages, and packaged MarkNote. Finally, Soumyadeep created Snap KCM, a graphical user interface to manage permissions that Snaps have when running.

Next Steps

The GSoC period is over, for all but one contributor, Pratham Gandhi. A follow up post will summarize contributions from the remaining project. Contributors have enjoyed participating in GSoC and we look forward to their continuing participation in free and open source software communities and in contributing to KDE.

The post Kdenlive 24.08.2 released appeared first on Kdenlive.
