Years ago, there was a blog on the planet with the title “How to crash (almost) every Qt/KDE Application and how to fix it“. In short, if you are showing a dialog, KWin prevents you from closing the application by clicking on the close button in the window decoration. However, through D-Bus, you can still quit the application. A solution was also provided: Use a guarded pointer to create the dialog.While this fixes the issue, it looks like fixing the blame, and not the real issue. Stricktly speaking, even the Qt documentation would be wrong then. Read More

Recently, there was a very good blog about The Importance of Mentoring. It was mentioned that the 3200 slocs of the gsoc projects could be cut down to 500 slocs, doing exactly the same thing. While hunting some crashes in the new code folding code from the last gsoc project, I obviously had a closer look on how things are implemented. The code folding uses a simple tree structure. Nodes can be added, removed or moved around. So I stumbled over the following code: Read More

In KDE SC 4.9, Kate Part will have an option in the Open/Save config tab called [ ] Append newline at end of file on save By default (and Kate tradition), this option is off. You can also use the document variable (modeline) newline-at-eof [bool], either in the file itself, in a .kateconfig file, or in the “Modes & Filetypes” config page. If a newline was added, it is visible only after reloading the document. This finally fixes wish #256134. Read More

As already mentioned, Kate Part much better chooses colors from the default KDE color palette configured in System Settings in upcoming KDE SC 4.9. As teaser, here are some examples – hope you like it. Default “Oxygen” Color Schema Default “Obsidian Coast” Color Schema  Read More

Now, the categories in the “Colors” tab are painted like in System Settings (top: new, bottom: old): Thanks to Rafael Fernández López for relicensing the code of SystemSettings’ CategoryDrawer under LGPLv{2,3}.

This week, Kate Part received an update of the “Colors” tab in the settings dialog, available in KDE 4.9. The major features include configurable colors: search highlight, replace highlight and modified line colors – finally :-) possibility to always use colors from the KDE color scheme. the implementation works in a way that at some point, the host application (KDevelop, Kile, …) can put items into this list. Here are screenshots of the new (top) and the old (bottom) color tab: Read More

Perhaps a bit early, but typical german, me and Dominik booked our flights to Tallinn. Lets hope we will have a lot fun there and meet old and new friends ;) See you all, at Tallinn.

On KDE 4.8.0, there is no way to disable the line modification markers. In KDE >= 4.8.1, you can disable them as follows by first closing Kate and then typing kwriteconfig --file katerc --group "Kate View Defaults" --key "Line Modification" --type bool false To enable it again, close Kate and run kwriteconfig --file katerc --group "Kate View Defaults" --key "Line Modification" --type bool true However, this only affects Kate; not KWrite, Kile, KDevelop or any other application using Kate Part. If you want to disable the markers for KWrite, Kile or KDevelop, use kwriterc, kilerc or kdeveloprc instead of katerc.

Since several releases, Kate Part has scripting support through javascript. So far, it seems it is not much used by users. Still, I stumbled over two extensions: jump to previous / next paragraph base64 encoding If you have more user defined scripts, it would be nice if you let us know! For KDE5, we plan to extend this, so applications like Kile or KDevelop can reuse Kate’s internal code. Read More
