Hey everyone!
Apparently “Application Integration from KDE Finance Group” is not taking place, instead Aleix and me will fill the gap and talk about KDevelop 4. We haven’t got any slides and only prepared roughly yesterday, but we decided just to show KDevelop 4 in action. Lets hope that there will be something in there for any interested KDE developer.
I’ll definitely show some assistants again, since apparently many people still ignore them even though they are imo one of the best features we have.
So come to room I at 12:15 :)
PS: Short note regarding KDevelop at Akademy: I’m pleasantly surprised again to see so many KDevelop users around. You all rock!

Hi there,
just a quicky before I head off to bed and go on a short vacation the next few days:
PHP support in KDevelop now has support for the first PHP 5.3 feature, namely namespaces. I’m still convinced that the syntax sucks pretty bad in PHP’s implementation of namespaces but well, my hands are tight and I had to support it. Anyhow, with PHP master you shouldn’t get syntax errors anymore when using namespaces, but instead proper code completion, syntax highlighting and context information… Well, full blown DUChain integration :)
Furthermore I just introduced the first few error recoveries in PHP that should make the situation a bit better when you work on a broken file. Up until now any parse error resulted in a file with no advanced PHP features at all until you fixed that parse error. Now it should at least skip parse errors in code segments between braces (classes, functions, conditionals, namespaces, …). It can be much improved of course, and I’ll do just that next week.

Heyho, me again :)
Seems like I have quite the urge to write blog posts recently… Anyhow:
The last two days I reimplemented / ported two features from Quanta 3 times to KDevelop (if you still didn’t get it: everything is a plugin, hece it will be reused in Quanta 4). What I’m talking about is most importantly the revival of a “execute external script” plugin. It’s currently still in a feature branch, but will hopefully be merged into master soon. But what can you do with it? Well, think about the following usecases and see how they can be solved with this plugin:
I want to compile and run a simple helloworld.cpp-like file without setting up a build environment nor do I want to setup a project for it.
Use an external script: _quick compile_. It just runs this command: `g++ -o %b %f && ./%f` In this code `%f` gets replaced with the path to the currently active file and`%b` is it’s basename (i.e. without extension).

Quick note:
I’ve just merged all webdevelopment related plugins except PHP & PHP-Docs into Quanta git. You can get them all in one place now by cloning Quanta: http://gitorious.org/kdevelop/quanta
Since I also moved all halfworking plugins to UNPORTED (they don’t get installed), you should be fine by just installing all of Quanta to get the plugins. If you only want one of them, going into it’s subfolder and building it standalone should hopefully still work though.
In other notes: Thanks to Ruan Styrdom for starting work on a PHP formatter plugin for KDevelop. It uses phpStylist and it’s already somewhat working. Awesome :)
/me is off to more GSOC hacking, bye

Hello everyone,
I have the urge to write a quick wrap up over the just finished LinuxTag 2010: All in all, I had a good time. Really, imo it was better than last time (granted though, last LinuxTag sucked pretty badly).
Anyhow, this time was my first shot at being a speaker. Boy was I nervous… I trembled quite badly at the beginning but got confident after a few minutes. Too many “ähm“‘s and “äh“‘s though ;-) Anyhow, I apparently did my job well enough: My talk was about KDevelop 4 - Faster C++ Programming. But yeah, I did it in German (it was my first talk on such a convention, and I was already nervous enough :P), but still - since I did a live presentation I was apparently able to impress even non-German speaking attendees by the sheer amount of visual coolness I could present :)
Really, the C++ features in KDevelop I showed are so nuts and awesome, I have to thank David and friends for implementing them in KDevelop. Great job everyone! It made my life as a speaker quite easy :)

Ok, finally I take the time to blog again.
The last two weeks have been a busy time for me and I couldn’t find as much time for GSOC as I would have wanted. I had to finish up some things at KDAB where I spent the last three months doing an internship (maybe I should write another blog about that eventually…). Afterwards I took five days of vacation, visiting a friend in Lisboa, Portugal - a very good decision to clear my head :) Esp. considering that I directly dropped back into my old job at the IT administration here at my university, where I had to quickly finish another project that I delayed until the last days possible ;-)
But… Even before GSOC officially started I already committed a few small things. But yesterday and today I finally started for good. Thanks to the discussion with Andris (my mentor) I actually think to know what I have to do ;-) Porting Quanta+ is not an easy task, even though there is already a Quanta binary that links against KDE4 and “works”. There are tons of files and hundres of lines of code commented out that are left to be ported. And I have to wager: What can I port in the few weeks left for GSOC and what should I drop for now? What is superseded, or should be eventually superseded, by a proper KDevplatform integrated plugin?

Hey everyone,
I spent some time today browsing teh interwebz to look at the responses our first KDevelop 4.0 release triggered so far. Quite fun I have to admit, given this is the first release of something I actively helped to develop that actually gets a response on the net ;-) What I noticed among the ‘I use VS’, ‘I use vi’, ‘I use ed’ comments (besides ‘I use emacs’):
- sadly we didn’t update the screenshots everywhere yet, making some people believe we actually look like kdev 3 still ;-) this is not true, take a look here: http://apaku.wordpress.com/2010/04/25/kdevelop-4-0-screenshots/
- yes we have support for PHP and everyone knows PHP sucks but still everyone uses it ;-) But few seem to notice that C++ is actually “just another plugin”. And we already have support for Ruby, Java and Css somewhat working in the pipelines. And very experimental stuff for C#, python and XML is also there. Imo what we said in the release announcement is true: KDev 4 is much more open for new languages than anything before. It does take some effort, true, but the result is much more pleasing.
- we’d really welcome new blood in our dev team, esp. for new language support plugins or things like automake, qmake and qt-designer support. there are outdated plugins available, someone just has to polish them…

Yay I got a GSOC slot :)
So I hope I don’t have to introduce myself anymore to you guys. Instead I’ll show you what I’ve planned to do over the summer:
Motivation for Proposal / Goal:
Back in KDE 3 times, Quanta+ was one of the reasons for me to use KDE. In my eyes it was the IDE for web development out there, and I loved to use it. Sadly it’s bitrotting nowadays without a finished KDE 4 port. That, combined with the fact that more and more distributions drop all KDE 3 packages, makes the need for a port more urgent than ever.
Implementation Details:
Thankfully, KDevelop 4 is nearing it’s first release and the KDevplatform is mature enough nowadays. This means that during summer I shall finish the port of Quanta+ to KDevplatform and supply it with all the plugins required for a proper webdevelopment IDE. My goal is it to provide a proper IDE for PHP webdevelopment. In more detail:
- make Quanta+ 4 compile
- remove obsolete plugins or code parts in Quanta+
- port required plugins to KDevplatform structure
- polish PHP plugin, including XDebug support
- polish Script Execute plugin
- polish CSS plugin
- get a first working version of a XHTML/XML plugin, if time allows even with HTML (SGML) support
- support autocompletion
- support inline validation
- support documents that use multiple languages (XML, PHP, CSS, JavaScript) at the same time
- polish the UI/Workflow for Webdevelopment
- hide KDevelop/C++ specific actions
- add templates for common PHP frameworks
- if time allows, get a rough support for JavaScript (at least Outline for functions)

Hey all!
I’m now abusing the fact that my blog is aggregated on the planet to bring this diamond of a documentary some more coverage it deserves so greatly. I’m speaking about Rip: A remix Manifesto. Go and watch it. Now!
I bet every single FOSS user, developer, advocate thrives in watching it. I’m totally blown away and hope that as many people as possible watch it.
And gosh - open source cinema , how cool is that :)

Ok, you should know by now that I love profiling and making things faster. Yet there’s always a “but”. For me it’s blocking syscalls, or anything that makes the app “slow” for the user but doesn’t show up in Callgrind as the Instruction Fetch cost doesn’t go up.
The usual suspect is of course locks (which we have quite a lot in KDevelop) or QProcesses with waitForFinished() or similar… You won’t see them in any Callgrind profile. Does anyone know a way to achieve that? Something that makes Callgrind increase the Ir cost for blocking func calls depending on the time it blocks? Or some other tool that would show me these?
And if you are interested: I was still able to find the cause for slow parsing of Custom Make Manager projects (Qt, Linux Kernel, …) in KDevelop: The cache in the IncludePathResolver never hit, since a operator== was improperly implemented ;-) I really wonder how we could have missed that for so long! I’ve also added some more changes that should make it much faster to parse projects that rely on the IncludePathResolver. I was personally now able to parse 10.000 files of the Linux Kernel in about 9.5 minutes. This is roughly a third of the Kernel, so I’d get to a total of approx 30min. Compare that to the 2.5h for 5% that one of our users reported ;-)
