  • » KDevelop PHP digest - August to Oktober 2009

    Fri, 10/02/2009 - 15:08

    Hi there again! I’ve been silent again on my blog, but didn’t rest on development. In the one and a half months since the last digest, I started writing a PHP application This finally made me eat my own dog food :). It resulted in lots of polishing and quite a few bug fixes for the PHP plugin in KDevelop. Here’s a list of what I think are the notably changes since the last digest:

    (Note: to view screenshots, go to the bottom of this article.)

    • refactoring of parts of the Code Completion code, should already result in faster code under certain situations
    • properly mark constants as “Kind: Constant” in the declaration tooltips
    • offer argument hints for ctors during code completion in class init statements
    • greatly improve the generate inline documentation of built-in PHP functions, classes, properties etc. pp.
      • add documentation of public properties
      • support aliased functions (thanks to Victor Grischenko for his patch)
      • show more/all documentation, and not only the first paragraph
      • fix type-lookup
      • don’t get confused when a documentation file documents both, a method and a function (greatly improves e.g. MySQLi documentation)
    • don’t offer “jump to declaration” for built-in PHP declarations
    • add support for list(...) statement
    • cleanup code-completion list, esp. show the return type of functions in the prefix field, and not something a la “function ReturnType ($arg1, $arg2, …)”
    • improve the code-completion for include/require statements
    • add language constructs to code completion (e.g. class, while, foreach, print, …)
    • show declaration tooltip for magic constants, showing their current value
    • make functions, methods and classes case-insensitive, just like PHP handles them
    • some performance improvements, especially in code completion and parsing of the generated file containing php-internal declarations
    • lots of bug fixes, don’t want to iterate them all ;-)

    I created a Flickr account and will push screenshots to it for every upcoming digest I do. To see some of the features I talk about above, visit: http://www.flickr.com/photos/milianw/sets/72157622375662249/detail/

    EDIT: A note to those that want to try this out , but cannot / don’t want to compile it: I heard that there is / will be an AUR package for Arch users available. And I’d really appreciate it if others could create packages for their favorite distribution as well. You’ll need bleeding-edge kdevplatform + kdevelop though!

  • » Spotlight: linux-minidisc

    Thu, 09/03/2009 - 18:36

    Hi there!

    Today I want to abuse the fact, that my blog is aggregated on some planets, to bring a project of a friend of mine into the spotlight:

    The Linux-Minidisc project

    It’s a project to bring Read/Write access on mini discs to Linux. It consists of a CLI and a Qt Gui. All code is licensed under the GPL and can be accessed via Git.

    To get a nice introduction about the project, read this excerpt from a recent Linux Journal edition: http://users.physik.fu-berlin.de/~glaubitz/minidisclj.pdf

    The project itself has a wiki under the following address: https://wiki.physik.fu-berlin.de/linux-minidisc/doku.php

    As every other FOSS project, Adrian and his fellow developers need more man power. Especially someone who can spruce up the Qt GUI is needed. Help them!

  • » Easily access quassellogs from the CLI

    Thu, 08/27/2009 - 16:56

    Quassel is really a cool program. I like how I can use it from everywhere and access the same set of data. Now using IMAP and Quassel I’d really look forward for similar shared access to other IMs, but that’s not the topic of this blog post.

    What I want to introduce is a new addition to my set of shell helpers, called quassellog:

    1. $ quassellog -u milian -b "#kdevelop" | tail -n 1
    2. [2009-08-27 13:09:11] milian > hi all
    3. $ quassellog -b "#kdevelop" | tail -n 1
    4. [2009-08-27 16:43:35] Fersis!n=Fersis@190.245.176.231 > yeah i did
    5. $ quassellog
    6. quassellog [-u USER] [-b BUFFER] [PATTERN]
    7.  
    8. -u USER show only messages from users, who have USER at
    9. the start of their sender name.
    10.  
    11. -b BUFFER show only messages in this buffer
    12. valid buffers are:
    13. ##linux #khtml &IMP ...SNIP...
    14.  
    15. PATTERN a simple pattern, use * for wildcard matching
    16.  
    17. NOTE: order of options is not exchangable, i.e. first -u, then -b then pattern...

    You can get the code from github. To make it work from all your servers I recommend the following alias:

    1. alias quassellog='QUASSEL_HOST=theHostQuasselCoreRunsOn quassellog'
    2. # e.g. for me:
    3. alias quassellog='QUASSEL_HOST=jongleur quassellog'

    That way the script runs automatically on the right server (provided it’s also accessible there under the same path). Have fun!

  • » Improved PHP support in Kate

    Wed, 08/26/2009 - 16:20

    Not only KDevelop gets better and better PHP support — the Kate PHP syntax file also got a few new features and fixes over the last weeks. The good thing is of course that all users of KWrite, Kate, Quanta, KDevelop and other editors leveraging the Katepart benefit from these changes.

    Improved HereDocs

    I went over PHP related bugs on bugs.kde.org today and spotted one that was fairly easy to fix:

    vim-like syntax highlighting support for heredocs in php.xml

    With some magic (IncludeRules just rocks) I got it working fairly easy. You can see the results to the right.

    Additionally I added code folding to heredocs, since often these strings include lots of text and hiding it often makes sense.

    Better support for overlapping syntax regions

    Another long standing bug (accommodate overlapping syntax regions (especially for php)) got fixed by James Sleeman.

    Finally PHP templates with code such as

    1. <?php if ( true ) : ?>
    2. <!-- some html stuff -->
    3. <?php elseif ( false ) { ?>
    4. <!-- some other html stuff -->
    5. <?php } ?>

    can be folded properly. This kind of spaghetti code is used quite often in simple templates and having the posibility to fold it properly is a huge win in my opinion. Thanks to James Sleeman again!

  • » News for PHP in KDevelop

    Sun, 08/16/2009 - 01:24

    So, after a period of silence I present you an unsorted list of features and bug fixes I did to the PHP plugin for KDevelop in the last few weeks:

    • added support for path autocompletion after require / include statements: This shares code with the Cpp plugin and it’s completion after #include. I plan to use this autocompletion eventually also for functions accepting filenames or paths. Think of fopen, file_get_contents etc. pp. So far only URLs that are covered by an open project can be completed. We will need support for custom include paths so we can support e.g. global PEAR or framework installations.

    • worked around a bug where the “schedule all project files for parsing” had no affect. Apaku is currently working on making some internal changes so I can remove the workaround and fix this properly. With this fixed/worked around you should retry the PHP plugin along with frameworks or similar to see how well it works. Just make sure to have the framework inside your project so it gets parsed.

    • fixed code completion of static class members for classes that where not defined in the current file

    • by sharing code with the cpp plugin I made it possible to show information about includes on hover. You can open the file from that popup or just see what classes, functions, variables etc. are defined there and jump to them quickly.

    • report errors when the user tries to include a directory

    • totally rewrite a huge part of the code completion: It now utilizes the token stream and can hence work much more reliably. Also the code is much cleaner in my opinion and it should be easier to extend its functionality. If you spot places where you think no code completion should happen or vice versa, please report that to me!

    • don’t crash on empty includes (i.e. include ""; )

    • ignore xml declarations (i.e. <?xml ... ?>)

    • support implicit declarations of referenced arguments, esp. important for e.g. preg_match("#...#", $string, $matches);, before the $matches was said to be undefined. Additionally references should be marked and shown as such now in the popups of e.g. function arguments.

    • support implicit array declarations, e.g. $a[0] = 1; // now $a is an array

    • fix bug which made the class browser not aware of changes in PHP class structures. Now we can see new classes, methods and members directly after writing them in a PHP file.

    • support /// comment syntax for doc-comments, especially useful for type hints of variables.

    • report error when someone tries to declare a class constant with an invalid type (i.e. not bool, int, float or string)

    I’m very happy to say that we seem to get more and more (happy) users!

  • » Dear Lazy Web: Hackable Mobile Phone with good Music Player?

    Mon, 07/06/2009 - 10:31

    Hey all, I need your help:

    I lost my Ipod and now have to live without music on the road… Sucks pretty much, I can’t live without music…

    Since my current mobile phone is pretty shabby I thought about fixing both in one go: Buy a mobile phone which could replace my Ipod as well!

    Now lets first say what I need most:

    • should’nt be too expensive: A new Ipod with 120gb costs only ~200€. So even though I hate that device, I doubt I’ll pay like twice the sum just to get something different…
    • It needs a “Klinke” stereo output, i.e. something where I can put my normal headphones in.
    • I need space for my music: My last Ipod (80Gb) was completly full… Ok, I think I can make a few cuts, though 8gb only is not enough. Hence the phone should support hot-swapping of SDHC cards at least.
    • If I buy such an expensive device, I’d like to be able to write my own software for it, or put existing software on it.

    What I found is the Nokia 5800 express music. It costs like ~260€. 16Gb more space costs like ~45€… It has stereo output and SDHC support. But what I don’t know: Where will custom software be saved on? Also on the SDHC? That would make hot-swapping kind of pointless…

    Good thing: It’s S60 5th gen, so Qt will run it and I can write my own software - that’s pretty cool. Though one question: Do I need Windows for the SDKs or can I develop under Linux?

    So… Does anyone have a better suggestion? Or any experience with that mobile phone? I really hate that there is no alternative to Ipods with a lot of space… Monopoly sucks! And I can’t even put my own stuff on such an Ipod… Not even Rockbox any more :( I hate Apple for that!

    But since I’m a poor student I somehow really doubt that I’ll get myself a new phone, esp. since additional SDHC cards cost quite much…

  • » Progress in non-cpp KDevelop4 land

    Wed, 05/27/2009 - 21:09

    Has been a time since I wrote the last update for PHP / webdevelopment related work in KDevelop4…

    XDebug

    First of all, Niko (nsams) is working diligently on the general debugger framework for KDevelop4. Of course gdb is still the main focus so far yet he always has his XDebug plugin (which is currently unusable) in mind. So expect some great debugging features once he’s done with the framework.

    Remote Projects

    Another thing I’ve not yet written about is a bunch of commits I did just after the Hackaton: Remote Projects! Yes, finally you can work directly on the server with KDevelop. I still have to make sure that the user does not try to open a remote cmake project (or similar), because that is of course not supported. Only the Generic Project Manager (basically a list of files in a dir) works. There’s for sure some things to polish, yet I’d like to see user feedback for that use-case at least.

    Note: There is still some functionality missing in other areas, like creating a new remote project from a template etc.

    Out-of-class declarations of member variables

    The PHP plugin itself got support for some more code, like declarations of members variables outside the class context which was reported by one of our early adopters (hint hint - do the same! we need more wishes and bug reports!).

    Improved DeclarationBuilder

    Additionally I changed the logic of our DeclarationBuilder so it does not create a new variable declaration for each assigment expression. I think this makes refactoring, use-highlighting etc. in a PHP environment much better for many cases. Sadly it is not yet perfect since we still need to redeclare variables when their type changes. Fixing that would require potentially big changes to the DUChain and I’m not sure when it will happen.

    Error Reporting

    Furthermore I’ve added some more inline error reportings, namely for redeclaration of $this in a class context. This is also an area where you might help us a lot: Send us PHP snippets which fail when executed but are not yet highlighted in the editor. I’ll try to add them then. Just use the bugtracker on http://bugs.kde.org.

    Performance

    Also David (dnolden / zwabel) of Cpp-KDev4 fame made some changes which resulted in a good performance win. Thanks!

  • » KDevelop Hack Sprint 2009 - Day 2 and 3

    Thu, 04/23/2009 - 01:31

    Ok, just a quick update on what we are doing / have done the last two days except drinking beer and eating quite a lot of food (though it never seems to be enough somehow….)

    • Apol was polishing CMake support, speeding up KDevelop startup time when you enabled the QtHelp plugin, making sure that Kross plugins get loaded properly and some other things
    • Adymo started some refactoring of Sublime in an experimental branch (actually they had quite a long discussion right now about things in the UI which should be changed/fixed). Besides that he also fixed some little bugs in the includepath resolver for CMake
    • Nsams is fixing PHP support and adding new features here and there. Esp. completion inside a foreach over a Iterator class works now!
    • and as always ZWabel did fix quite a lot of bugs, most of them which only were discoverable in a few corner cases, very nice indeed.
    • shaforo who sadly already left us again to attend university fixed the sorting in the Project view among other things
    • With Apols help I managed to get started with a documentation plugin which (currently) integrates PHP.net. I plan to make it possible to use the downloadable PHP.net documentation as well to speed things up. Actually setting up a documentation plugin is very easy! Maybe I’ll take a look at writing a documentation plugin for Zend, Symfony, etc. pp. as well - should be fairly easy. Maybe I can come up with a generic documentation plugin which makes it possible to include any kind of .html documentation with some configurable mapping… lets see! Or maybe I should take a look at writing Kross plugins (Apol could help me here as well) for that purpose.

    Except these changes we also discussed how to support dynamically typed languages like PHP, Ruby, Python and JavaScript better. One result of it that we now plan to fully support the dedicated map types of each language, with autocompletion and such. Of course that won’t be possible for 100% of the use-cases, but we hope to support at least the most common ones (i.e. 90%). You can take a look at http://www.kdevelop.org/mediawiki/index.php/SupportForDynamicMaps for more information.

    Additionally Nsams, Apol and Zwabel took a look at the GDB plugin and started working on it a bit. It’s still a work in progress though.

    My biggest change is that color highlighting support for dark color schemes now is in trunk. It automatically adapts to changes in the global KDE color scheme, yet you still have to manually change the Kate color scheme. Actually I intend to add an interface to Kate so we can use it’s color schemes instead of the global KDE one - makes much more sense and would fix some bugs (i.e. fix from dark color scheme to a light one). Here’s a screenshot of it (with the PHP.net documentation showing):

    highlighting in kdevelop with dark color scheme
    dark color scheme and syntax highlighting in KDevelop 4

    If you followed the planet kde you might have seen some blog posts about color reception and color generation by Ariya Hidayat. I will take a look at it and implement it in KDevelop. Or I simply pick a given set of colors and use them - for 10 colors or so we need it doesn’t make that much sense to let them be generated. Yet the article he linked to about adaptive coloring for syntax highlighting will be helpful I think! Thanks!

    Yet it currently works quite well I’ll first try to fix the colors in the Declaration tooltip, quickopen and codecompletion lists.

    So stay tuned for more KDevelop goodness throughout the next days.

  • » KDevelop Hack Sprint 2009 - Day 1

    Mon, 04/20/2009 - 23:01

    Ok, a short blog about the first day of our KDevelop Hack Sprint at Mykolayiv (see my first blog post). First up, being in the Ukraine is a very interesting experience since it’s totally different from any place I have ever been to. And thanks to the great hospitality of Alexander (adymo) we already had a city tour of Odessa and Mykolayiv.

    Tomorrow will be the first real day of our hack sprint: Today we only hacked at our flat for a few hours. Before that we had the city tour through Mykolayiv. And tomorrow David Nolden (zwabel) and Nick Shaforostoff will arrive which will make the list complete.

    Today I personally worked on making KDevelop support dark color schemes better which is still a work in progress (nothing comitted so far). Actually for a real good experience I’ll have to extend KTextEditor to make it’s color configuration available for the parent application (i.e. KDevelop). Let’s see when I get to that. Though I plan to push my patches to KDevplatform beforehand for an intermediate solution.

    Random other notes about Ukraine: - I love the Vodka (esp. with its prices) here! - breakfast at a cafe is pretty much a no-go here it seems - street lights are luxury - very many old building all across the city, looks pretty good. Though would look even better if all of them would be in a good shape… Yet I still prefer it that way - I hate what was done to Berlin after the war, i.e. that they teared most of the old buildings apart instead of repairing them…

    So, lets see what tomorrow brings, now I’m back to some more hacking :)

  • » About being a Nerd

    Tue, 04/07/2009 - 23:41

    A quick meta-blog about nothing directly KDE related, but I think those of you who can understand German should see it nonetheless. Hope you don’t mind me spreading it on the planet:

    I just stumbled upon a great video about the definition of “being a nerd”. You can watch it here:

    http://www.elektrischer-reporter.de/elr/video/115/ (note: it’s in German!)

    I have to say that I can identify myself with the message of the video, very nicely done. Must see for anyone! I’ll spread it in my circle of friends so they understand me better when I talk (proudly) about being a geek.
