KDevelop 4.1 Beta 2 will be omitted, stay tuned for Beta 3 (September 21, 2010)

Hey everyone.

I was on a spontaneous trip last week and missed the Beta 2 release. Apol took over but my instructions where not clear enough and the packages where totally screwed up (the tags pointed to code in master, no the 4.1 branch).

I’m in the process of fixing things up and will create tarballs for Beta 3 and announce it to packagers later today.

Lets hope the actual release for users out there can happen later this week.

Sorry again, bye.

Highlighted Backtraces on BKO (September 20, 2010)

Hello everyone, the “I can syntax highlight everything” guy speaking again :)

Yeah, I couldn’t sleep well after I put colors on Dr Konqi. I also did the same for Kate, if you did not notice it. There is a new GDB Backtrace syntax highlighting file for it, giving you the same pleasant experience you are now used to from Dr Konqi. Awesome.

But well, lets admit it: What use are these two for bug triaging? Visit any crash report on bko and you are left to plain old black-on-white… Stone-age stuff, lets put it on LSD, shall we not? I propose: The GDB Backtrace highlighter GreaseMonkey userscript!

Bug reports, feedback, pizza & beer all welcome :)

Beware of KDevelop Master and KDELibs 4.5.1 or lower (September 10, 2010)

Hey all,

please don’t use KDevelop master with KDELibs 4.5.1 or lower. Katepart in that version misses a crucial commit that makes KDevelop crash. It is fixed for 4.5.2. In the meantime you have on of the following options:

  1. Build kate from sources
  2. Switch to the stable branches, i.e.: KDevplatform 1.1, KDevelop 4.1, PHP 1.1, …
  3. wait for the 4.5.2 release

Short GSOC 2010 Note (August 22, 2010)

Hey all,

before I go on a short one-week vacation, I wanted to leave you a short note about the outcome of my GSOC, where I tried to revive the Quanta+ brand.

First up, I passed, many thanks to my mentor Andras Mantia. But well, it’s not like I got that for free. In a first estimation I did about 500 commits to Quanta, PHP and KDevplatform in the last three months. So I hope you all agree that I deserve the Google money :)

But lets talk about what I planned to achieve and what I actually achieved:

  • the XML/HTML plugin is working quite well but is still requiring lots of polishing
  • the browser preview plugin is supposedly being worked on by another studen in Brazil, I’m awaiting her first results and will polish it together with her.
  • you still cannot rename tags and automatically rename the close tag as well or similar
  • the multilang branches have imo nice API additions and seem to work reasonably well. At least my test cases of CSS inside HTML worked fine for me

Anyhow, on one hand I’m personally satisfied with what I achieved code wise, esp. looking at the diffs and knowing how many iterations some of the multilang structures required. On the other hand I had hoped to achieve much more. A first alpha release of Quanta is really not visible to me in the near future.

Dr Konqi now with colors (Updated) (August 20, 2010)

Hey there :)

As I announced on the kde-core-devel mailing list, I planned to improve Dr Konqi for a long time, as for me as a developer it is an invaluable tool. Well, yesterday I sat down and implemented the first two things which I wanted for a long time:

Scroll to KCrash

Once the backtrace got loaded, Dr Konqi will automatically scroll to the line that contains [KCrash Handler]. No need to find that manually anymore. Awesome :)


Yeah, you should know that I as a KDevelop user and developer am addicted to syntax highlighting. That’s what I did for Dr Konqi as well now:

dr konqi with syntax highlighted backtrace
Dr Konqi with syntax highlighted GDB backtrace

So anyone using KDEBase trunk will now have a shiny Dr Konqi :) Feedback appreciated, esp. whether more or less should be highlighted. I personally found it overly colorful when I also highlighted pointer adresses (ignore the bug in that outdated screenshot). What do you think?

Final days of Quanta GSOC 2010 (August 04, 2010)

Hey everyone,

as the pencils down for this years GSOC is approaching I thought it’s time to write another blog entry to notify the world about my current status.

These past weeks (boy, the time flies…) I’ve mostly spent on hardcore KDevplatform internals. Especially getting multiple languages in a single document working was not easy. I knew it would be the most time consuming and most demanding aspect during these three months, but also by far the most important. I’m confident to say now: I’m nearly there. All projects we put into the KDevelop repository have now a multilang branch in their team clones. And if you look at e.g. the KDevplatform multilang branch or the Quanta multilang branch you hopefully agree that I didn’t slack off too much. I just wasted some time to find the right approach, often by implementing one just to find out it was not practicable.

Spotlight: Kate Scripting (July 27, 2010)

Hey ho everyone.

Dominik asked me to blog about a feature in Kate that is still (sadly!) pretty unknown and seldom used: Kate Scripting. As you should know you can script KatePart completely via JavaScript. As those articles explain, it’s rather simple to write functions and put them into a file to have them reusable. But what for those write-use-throwaway kind of cases, where you simply need to get a job done quickly and don’t want to go through the overhead of writing some full fledged, documented, action-binded, localized script?

Utility Functions and why JavaScript rocks

Note: Neither map nor filter will be shipped with 4.5 to my knowledge, sorry about that. But you can still use the each helper (see below) to achieve the same with a bit more typing…

KDevelop 4.0.1 released (July 21, 2010)

Good news everyone!

I’m happy to announce the availability of our first patch level release for KDevelop 4. You can get it and the related packages from:

This is a bugfix only release and everyone is urged to upgrade as soon as possible. Below you find a list of changes that went into this release.

Users should wait for their distributions to provide packages for them.

Thanks to the KDevelop contributors for making this possible and to the users for giving us valuable feedback.

PS: I hope to release a second patch level release in a month, assuming we find more to fix.

The problem is: when the error message is shown, the eventLoop is reentered, the job is deleted. The emitResult() call after tries to use the deleted job -> crash. This might be only a workaround, but fixes bug 229557 (and its duplicates), bug 227823, bug 232444, 227584.

    * Hugo Pereira Da Costa: Fixed setting of maximum height for button and stack so that expander arrow pixmap is not trunkated when small font is used.
    * Hugo Pereira Da Costa: Removed unnecessary calls to "setAutoFillBackground(true)". this allows main window background gradient (if any) to be painted right. (like in e.g. oxygen, bespin). Does not affect other styles.
    * Hugo Pereira Da Costa: Keep vertical size policy unchanged when embedding KLineEdit inside toolbar.
    * Hugo Pereira Da Costa: Rotate back icon so that it is still painted horizontally even for vertical buttons Use option->iconSize to decide which pixmap must be rotated.
    * Hugo Pereira Da Costa: This patch modifies the painting of sidebar vertical toolbuttons so that - the button frame is painted "non-rotated" - only the text is painted rotated. This fixes how buttons shadows are rendered. Screenshot at

Quanta GSOC midterm evaluation (July 08, 2010)

Hey there!

Midterm evaluations for GSOC are coming up and Andris Mantia, my mentor I finally met at Akademy, asked be to blog about what we already have in Quanta. Because there is a lot and most of you are not aware of that. And to be honest it’s actually too much to put into a single blog post, so I hope to do more of a series of blog posts showing off some features.

Quanta 4 is not Quanta 3

Anyhow, I fear that a disclaimer is in place, for all of you who are desperately looking forward a KDE4 version of Quanta. The thing is, I cannot, nor do I want to, port Quanta from KDE3 times as-is to KDE4. Instead I build on top of the KDevplatform that is also used for KDevelop and KTechlab. By sharing the basic code it gets much easier to maintain Quanta in the future. This decision brings two things with it:

  1. We get an awesome library to built new stuff on top, making things like the new PHP which is already much more advanced than anything from KDE3, actually plugin possible.
  2. We don’t have all features from Quanta 3 or if we have, they might look and work differently. This also means that you won’t be able to take your Quanta 3 workflow without changes over to Quanta 4.

Massif Visualizer - now with user interaction (July 08, 2010)

Just a quick status update: Massif Visualizer now reacts on user input. Meaning: You can click on the graph and the corresponding item in the treeview gets selected and vice versa. It’s a bit buggy since KDChart is not reliable on what it reports, but it works quite well already.

Furthermore the colors should be better now, peaks are labeled (better readable on bright color schemes, I’m afraid to say…), legend is shown, …

Now lets see how I can make the treeview more useful!
