» KDevelop 4.0.2 and KDevelop 4.1 Beta 1 released

Sun, 09/05/2010 - 19:13

Good news everyone, this time in a double feature!

I’m happy to announce the availability of two new additions to the KDevelop release family:

KDevelop 4.0.2 stable release

Lets begin with the boring part: We have released KDevelop 4.0.2, together with KDevplatform and the PHP plugins. You can find the sources here:

http://download.kde.org/download.php?url=stable/kdevelop/4.0.2/src/

This is a bugfix only release and everyone is urged to upgrade as soon as possible. Users should wait for their distributions to provide packages for them. The tarballs contain changelogs if you are interested what happened since 4.0.1. Or read them online:

Note: This is (most probably) the last release in the 4.0 branch. We don’t have enough manpower to handle more than one stable branch. Which makes me come to the second part of this mail:

KDevelop 4.1 Beta 1 experimental release

We are very happy to publish KDevelop 4.1 Beta 1, which will be the branch we are concentrating on in the next time. You can find the sources here:

http://download.kde.org/download.php?url=unstable/kdevelop/4.0.80/src/

This is a preview release. We are gratefully welcoming any testers and feedback to polish it further for the final 4.1 release which will probably happen around mid October. Please put the reports on the usual places, e.g. http://bugs.kde.org. If you are interested in the (quite long) list of changes, look into the tarballs again for an extensive git changelog. If you just want a few highlights: Git Support Plugin, External Script Plugin, general polishing, CPP support improvements, lots of bug fixes, UI polishing, performance improvements, … you name it :)

For the fun of it, here the list of commits changes for 4.1 (imo far too big to show anything useful):

Thanks as always to the KDevelop team for making this possible and to the users for giving us valuable feedback.

Bye

PS: Sorry that I forgot to announce this yesterday or even Friday, as I initially planned. Well, weekends are such a nice time to go outside and enjoy life :)

» Final days of Quanta GSOC 2010

Wed, 08/04/2010 - 01:38

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.

Thanks (once again) to the help of David Nolden I’m now on the right track. Finally :)

When you use the multilang branches (note: you’ll have to use them everywhere as they contain binary incompatible changes to the master branches), you should already get proper DUChain integration for CSS inside HTMLs <style> tags, which is what I used for testing purposes. I’ve just pushed the required changes to get code completion work properly as well.

This is all still in a quite rough stage and needs lots more work but it proves that I’m getting there. Once this is done I can continue to polish the CSS and XML language plugins, as well as finally writing a “preview HTML” plugin, as this was probably the most requested plugin from back then.

Looking at my tentative timeline for GSOC, I’m afraid to say that I didn’t get to do all of it. But I’m quite proud of what I achieved and hope you all agree that my time was well spent on Quanta. I won’t stop working on it probably after GSOC, quite the contrary. I still hope to release at least some alphas this fall and maybe get it into beta state in winter. What about a Quanta 4.0 release in spring 2011? Who knows :)

Bye

» KDevelop 4.0.1 released

Wed, 07/21/2010 - 16:28

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:

http://download.kde.org/download.php?url=stable/kdevelop/4.0.1/src/

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.

Bye

» KDevelop 4 talk at 12:15 today!

Sun, 07/04/2010 - 08:43

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!

» KDevelop PHP Advancements: Namespaces and Error Recovery

Thu, 06/24/2010 - 02:08

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.

Bye!

» KDevelop - ExternalScript plugin

Wed, 06/16/2010 - 14:06

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).
I want to sort / uniq / … the selection in the current document.
Here you can either use Kate Scripts, which gives you the same features. But to show you the capabilities of the external script plugin, this is a good example:
Setup an external script, that gets the current selection (or the whole file if nothing is selected) piped into it’s STDIN and let the selection (or, again, the whole file if nothing was selected) in the active document get replaced by the STDOUT of the external script. I’ve added an example doing just that.
I want to google for the selection in the active document.
I got this example from the External Tools plugin for Kate, and made it possible to do that with the new plugin in KDevelop. Simply use the following script: xdg-open "http://google.com/search?q=%s"
Note: %s gets replaced by the shell-escaped version of the selected text in the document.
I want to run an external syntax checker on my file / folder / …
Simply use an external script for it :) With the various %... placeholders it should be easy enough to do.

Here are a few screenshots showing the tool in action:

Second feature that I pushed in, which you can also see in action for the external scripts, is the possibility to assign shortcuts to snippets and external scripts. Eventually I’ll also try to bring back the “user toolbars” from Quanta 3 times, but I hope to do that properly inside KDELibs for reuse by other applications.

Another thing: In Quanta 3 times it was easier to create external scripts that showed some UI and asked for more user input. This is not possible since Kommander (which was used back then) is not available nowadays. If someone polishes the afaik halfway working port, I’m willing to implement it again. Anyhow I think nowadays one should use Qt Designer and Ruby or Python bindings to create UIs. Sure, a bit harder but much more powerful.

But well, now it’s your turn to write cool external scripts :) And to give me feedback: What kind of scripts would you write? What %... placeholders do you need?

PS: Even though I booked flights and accommodation ages ago, I haven’t yet announced it in proper KDE-style yet:

I'm going to Akademy 2010

» KDevelop Webdev plugins merged into Quanta GIT

Sun, 06/13/2010 - 17:18

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

» LinuxTag 2010 WrapUp

Sun, 06/13/2010 - 01:49

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 :)

If anyone is interested in the German talk (audio is good, visuals not really…), you can download a 23min part of the talk on rapidshare: http://rapidshare.com/files/397758262/Milian-LT2010.M4V.html (Thanks to Adrian for recording and uploading it!)

What this talk showed me in retrospect, esp. combined with the feedback I got afterwards and the recurring nags in #kdevelop on freenode, is that we are in dire need of writing documentation for KDevelop. Since we devels don’t have much time for that (and it’s boring…) I think/hope to write at least a short blog series about “hidden” features, i.e. the stuff I showed in my talk. Starting with that, I hope that one of you, dear readers, steps up and creates a proper Docbook documentation out of that :)

Oh and yeah, I had quite a few chats with the friends from QtCreator developers over at the Qt/Nokia booth. They do a quite good job at catching up with us apparently :P Well, that’s what they have their payed developers for after all ;-) One real “advantage” KDevelop has though, is that it’s inherently language agnostic. The Qt guys have of course no intention to support e.g. PHP. We otoh want that - and already do so. I had a few chats with (sometimes future) users of our PHP plugin and got quite good feedback, which I want to implement eventually. Even so, I actually started implementing the first features for PHP 5.3 support: Namespaces. If someone wants a good laugh, look at how that is designed for PHP 5.3, it must have been a drunken Windows guy that never used Namespaces in any other language before… sigh.

Anyways, back to LinuxTag in general: It was of course nice again to see so many fellow KDE developers and supporters. Also seeing the good old Ubuntu Berlin and LinuxTag crowd I “know” now after four years here, was a good thing. What I have to say is that attending a conference and actually taking the time to visit a few talks is much nicer than staying at the booth all time. Yes, sorry Eckhart for even doing some hacking on the booth, but we should all take that time for ourselves. We’ve been a large crowd at the booth nevertheless, esp. since we had the combined manpower (and women!) of Amarok, Kubuntu and KDE! And attending conferences and having some quiet time makes booth-work much more bearable. It’s not like I didn’t talk to people though, quite the contrary. But as always (esp. at events like LinuxTag), you get to talk to at least one insane person every day ;-) And after the second you kind of start to loose your faith in humanity… :P

Nice as always were the social events surrounding the fair-hours, most notably of course the “friends of Qt/Nokia” dinner that served us awesome food once again. The social event of the LinuxTag at Thursday was much better than last year (even though / because?) it was sponsored by Microsoft this year. Good job that we == KDE rocked the dance floor of course ;-) Tonight we wrapped it up with the usual Ubuntu BBQ at cbase, a nice end to an imo good event. If they can improve it some more next year by pushing the community aspect more once again, I’m confident that LinuxTag in Berlin could become as good as it was a few years ago!

Anyhow, now I really have to do some more catch-up for Quanta GSOC ;-) Good night!

» First Days of Quanta+ GSOC 2010

Fri, 06/04/2010 - 22:16

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?

But well, I think I know what to do for the next few days:

  • make Quanta specific code specific to Quanta (yeah, cool eh :P)
    currently QuantaCore is a plugin and hence also shows up in KDevelop showing Quanta specific stuff there, not nice
  • spruce up Ruan Strydom’s XML plugin for KDevplatform and purge the DTEP stuff in Quanta while merging as much as possible
  • make the ‘insert tag’ etc. pp. related actions, toolbars from Quanta3 work again
  • polish Niko Sams upload, css, xdebug, execute script, execute browser plugins

If I manage most of these, I’m confident to say that I reached an important step towards a once again useful Quanta. Lets see how it works out.

» KDevelop 4 - Looking at the feedback

Mon, 05/03/2010 - 23:46

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…

But all in all I’m amazed by the trolling/feedback ratio. It’s a really good feeling to see so many positive comments on various websites and $random-stranger defending KDevelop against the forces of the trolls :)

I’ll definitely continue working on KDevelop and make sure we’ll continue to improve over the time. This is just the beginning evil laughter :)

Btw. funniest comment on heise.de (German): KDevelop 4.0.0 is a released intended for developers. Of course, it’s an IDE, duh :P
