getting the dependencies

First, you’ll need to install some packages to satisfy dependencies and to get a working compile chain (think cmake, gcc and stuff). The following command only lists very few packages but they have a huge list of dependencies which your package manager will take into account automatically. Don’t be suprised by a possibly huge list of packages ;-) So some disk space will be required (though I doubt it’s more than 250MB in total).

Building KDevplatform, KDevelop and the PHP plugin from Git (March 06, 2009)

It is generally a very good idea to read some articles on the techbase. Especially in the Getting Started section.

PHP support for KDevelop 4 (and eventually Quanta+) (March 03, 2009)

Hello Planet KDE!

I want to give you a little insight on the current state of PHP support in KDevelop4:

Me and Nikolaus Sams (nsams) are working diligently on a plugin for PHP support in playground. It’s somewhat stable, i.e. we fix any crashes we stumble upon, but I would call it Alpha state at most. It may eat your babies so to speak. Yet I’m happy to say that at least one user is already using it for production (hi leinir ;-) ).

implemented PHP support

Well, here’s a (not complete) list of features that are already working. Though I have to warn you: no screenshots included ;-) It’s actually all very similar to the C++ screenies you can see on the web.

sematic highlighting

Let’s start with a feature that only very recently was added for PHP - semantic highlighting. Niko moved some language independent parts of the C++ plugin from KDevelop to KDevplatform and now PHP has the same code highlighting features as C++.

PHP "is_whitespace" performance (February 12, 2009)

Easy question: What is the fastest way to determine if a string in PHP is whitespace-only?

Easy answer: ![preg_match](http://www.php.net/preg_match)('[^\s]', $string);

Read on for the explanation:

I applied the codeblocks feature of my profile.class.php, here’s the testcase:

    <?php
    require 'profile.class.php';
     
    $iterations = 10000;
     
    profile::codeblocks(array(
      'trim(long string) == ""' => 'trim($long) == ""',
      'trim(long string) === ""' => 'trim($long) === ""',
      'rtrim(long string) == ""' => 'rtrim($long) == ""',
      'rtrim(long string) === ""' => 'rtrim($long) === ""',
      'ltrim(long string) == ""' => 'ltrim($long) == ""',
      'ltrim(long string) === ""' => 'ltrim($long) === ""',
      '!preg_match("[^\s]", long string)' => '!preg_match("[^\s]", $long)',
      'ctype_space(long string)' => 'ctype_space($long)',
      'trim(short string) == ""' => 'trim($short) == ""',
      'trim(short string) === ""' => 'trim($short) === ""',
      'rtrim(short string) == ""' => 'rtrim($short) == ""',
      'rtrim(short string) === ""' => 'rtrim($short) === ""',
      'ltrim(short string) == ""' => 'ltrim($short) == ""',
      'ltrim(short string) === ""' => 'ltrim($short) === ""',
      '!preg_match("[^\s]", short string)' => '!preg_match("[^\s]", $short)',
      'ctype_space(short string)' => 'ctype_space($short)',
    ), array(
      'long' => str_repeat(" \n\t ", 500) . "a" . str_repeat(" \n\t ", 500),
      'short' => str_repeat(" \n\t ", 5) . "a" . str_repeat(" \n\t ", 5),
    ), $iterations);
     
    profile::print_results(profile::flush());

profile.class.php (June 24, 2008)

Every now and then I want to profile a given part of PHP code. For example I want to quickly check wether my current changeset to GeSHi works faster or is horribly slower. For a big change I’ll stick to Xdebug and KCachegrind. But for a quick overview? Overkill in my eyes.

Say hello to profile.class.php, a simple timer class for PHP5 which you can use to get an overview about where how much time is spent. This is in no way a scientific method nor should you take the results of a single run as a basis for you decisions.

I’ve set an emphasize on an easy API so you don’t have to pollute your code with arbitrary hoops and whistles.

UPDATE: You can find the current updated source in the SVN repo of GeSHi.

Simple example

This is a quick example on how you could use the class:

    <?php
    require 'profile.class.php'; // should be obvious ;-)
     
    // here might be uninteresting code
     
    profile::start('overall'); // start a timer and give it a name
                                       // we add this one to get a time
                                       // for the overall runtime
     
    // this is the code you want to profile
    profile::start('$_SERVER');
    $foo = count($_SERVER);
    profile::stop(); // stop the last active counter
     
    profile::start('$GLOBALS');
    $bar = count($GLOBALS);
    profile::stop();
     
     
    profile::stop(); // stop overall timer
    profile::print_results(profile::flush()); // print the results

recent GeSHi contributions (apache, xorg, apt, performance, ...) (June 18, 2008)

Your favourite syntax highlighter for web applications, GeSHi, recently got some new features and bug fixes. By yours sincerely. A rough summary of what I contributed:

various performance improvements, i.e. some speed optimizations and reduced memory consumptions (especially peak memory usage is down by roughly 1MB when highlighting geshi.php by itself)
minor bugfixes, including one which prevents some nasty PHP notices on PHP 5 systems to contaminate your precious log files
improved language files: bash, apache
added language files: GNU Gettext, Xorg configuration and Apt sources.list

Some of those features were already shipped with the recent 1.0.7.22 release. But the two new language files and the improvements to the existing apache language file are currently only available via SVN. Wait for the next stable release which should be 1.0.8.

Drupal modules and other configuration (June 11, 2008)

Drupal is such a pleasing piece of software.

Just a few days ago I found some very cool new (to me) hidden functionality. Additionally I’ve installed some more modules which I want others to be aware of.

available updates email notification

Let’s start with the “hidden” functionality: Drupal 6 incorporates some parts of a Drupal 5 module which notifies you about available updates (see /admin/reports/updates). Pretty easy to stay updated with that alone. But I thought I’d had to check that page frequently for new updates. Not so! Say hello to the tab “Settings” on the very page and insert your email address to stay updated via email. Satisfying and built-in… dumb me searches in vain for a module with that functionality…

Yet it brought my interest to other useful modules:

Logging and alerts

The Logging and alerts module gives you a way to send emails to an email address of your choice in case of errors etc. Pretty neat since I don’t want to lose time by regularly scanning my log entries…
