I have the pleasure to announce the releases of two new KDevelop versions:
On one hand, there is the new and shiny KDevelop 5.0 Beta 2 release, which brings us much closer to a final release. Tons of issues have been resolved, many features got polished, and even our UI cleaned up a bit here and there. And did I mention impoved OS X and Windows support? See here for more:
Besides this new beta release, which is where most of our effort went into, I am also happy to announce KDevelop 4.7.3, a new bugfix release of our latest stable KDE 4 based KDevelop. Several annoying problems are resolved now, see the announcement for more information:
Many thanks to everyone involved!

I’m very glad to finally announce the first beta of KDevelop 5.0.0, based on Qt 5, KF 5 and Clang: https://www.kdevelop.org/news/first-beta-release-kdevelop-500-available
Like I’ve said previously, I’m very thankful of the tons of contributors that made this step possible. From the early testers, over the many new KDevelop contributors who helped a lot in porting our code base to Qt 5 and KF5, to the people that worked on improving kdev-clang and all the other areas. It’s a great feeling to finally release this beast. A year ago, just after we started in this process, I still wasn’t too sure we can pull it all off. Now, look where we are :) “Just” a few more weeks of polishing and I’m positively sure KDevelop 5.0.0 will be a really good milestone.
That said, I also want to express my thanks towards the KDE e.V. which graciously sponsored our recent KDevelop/Kate sprint in Berlin. We rented a flat for the 8 hackers that visited Berlin and had a productive five days directly after the Qt World Summit. Personally, I worked on kdev-clang and polished it a bit more in the preparation of the first beta release. One handy feature I added is the display of size information about classes and member variables, displayed in the image to the right.
it’s my pleasure to announce the immediate availability of KDevelop 4.7.1. This release contains many improvements and bug fixes - everyone is urged to upgrade. Distributions should already provide updated packages, otherwise you can download via:
Thanks to all contributors, users and bug reporters for making this release possible!
It’s my pleasure to finally announce the availability of KDevelop 4.7.0:
This is a special release, as it marks the end of the KDE 4 era for us in terms of feature development. We will continue to support this release in the long-term with bug fixes though. New things and fundamental changes will only happen in the frameworkified master branches from now an.
Many thanks to all contributors!
Kevin just announced it on the mailing list, the CI is still shaking it’s head, and we are all very curious about the coming weeks: KDevelop’s master branches are now depending on KF5!

Cheers, happy hacking and hope to see some more patches :)
just a quick announcement: KDevelop 4.7.0 Beta 1 was released! Head over to the announcement on the KDevelop website to read more:
Cheers, see you soon with a KDevelop 4.7.0 stable release :)
Time flies… The extremely productive hack sprint at the friendly Blue Systems office in Barcelona is over for more than a week. I haven’t had time to blog about the last days yet which I hereby make good for!
I spent a lot of time at the sprint polishing the KDevelop Clang plugin. A up-to-now semi-secretly developed language plugin based on clang which will replace our current C++ language support in KDevelop in the long-run.

KDevelop’s current C++ plugin
But a bit of history first: KDevelop’s current C++ language plugin can pull off what it does by essentially implementing (parts of) the C++ standard. We have our own C++ parser, we have our own implementation of the C++ template mechanism, we have our own share of “compiler bugs”, …. It should not surprise anyone that this is a maintenance nightmare. And indeed, with C++11 and the wealth of changes it came with our language simply fails in many areas. The current codebase is big (~55k sloc) and adding support for complicated features such as variadic templates or constexpr is extremely hard and fragile. So instead of doing that, my colleague Olivier JG started looking into using clang of LLVM fame instead. It promises an API for third-party tools to steer a C/C++/Objective-C compiler to their needs. Its the magic bullet which we waited for, and which did not exist back when KDevelop 4.0 was started initially.
Hey all! Greetings from the joint Kate/KDevelop sprint at the Blue Systems office in Barcelona!
I only arrived yesterday but already I have great news for you: After months of work I finally merged the
sharedurls branches into master for KDevelop/KDevplatform etc. pp. There I worked on a optimization in our handling of file paths.
The status quo up until know was the following: When importing a folder as a project in KDevelop, we filled a model with every file and folder in the project (recursively). For every item we also stored its path as a
KUrl to the potentially remote location.
QUrl are awesome when you have to work with paths and urls, but as soon as you store potentially thousands of them at the same time it becomes quite inefficient. Assume e.g. you open
/foo/bar/blub/ which contains
/foo/bar/blub/bla.h. When you use
QUrl to store these paths, you cannot share any memory between the two, as internally basically a
QString is used. Thus, when you import deep folder trees or folders with many files, you’ll waste a lot of memory for common sub-paths. Furthermore, due to the amount of allocations required, reading the tree is pretty slow.
Holy moly yet another KDevelop release - but this time a big one! Go and get 4.6.0 while it’s fresh and read the full announcement on the KDevelop website:
since some people asked me: The slides to my extended Apps on Speed talk from this year’s Qt DevDays Berlin are available for download. If you are interested, get them here: http://devdays.kdab.com/wp-content/uploads/2013/11/qt-dd-2013-apps-on-sp…
I hope you liked that talk. I certainly had fun presenting it and discussing the contents with various attendees later on. I have now quite some ideas on how to extend the talk even further.
The slides of the other presentations are also available. Stay tuned for the video recordings of DevDays Berlin, I’m sure they will be accessible soonish :)
Edit: The video is now available! Enjoy http://www.youtube.com/watch?v=C5EPt50Kgmc
