PhpStorm plugin development series

juzna.cz — Fri, 27 Jan 2012 00:45:26 +0000

I started developing a custom language plugin for PhpStorm, the best IDE for PHP I've met so far. But since the documentation for plugin development is rather poor and I have to dig in the code a lot, I decided to share my hardly gained knowledge with others. So first things you'll (I'll) need to start: Learn Java […]

Mock vs final fights in testing

juzna.cz — Mon, 16 Jan 2012 17:48:51 +0000

There has always been a war between testers, who love mocking all classes, and library developers, who prevent misusing their code by means of final keyword. You cannot do both. Once a class (or method) is declared as final, it cannot be mocked (extended). Since testers need to test their applications built on top of […]

Extending Nette Debugger

juzna.cz — Sat, 31 Dec 2011 11:00:18 +0000

Nette Debugger (or Laďenka by it's Czech beautiful name) is very helpful when solving problems, because it displays exceptions in a lovely way. Sometimes it's not enough though and you'd like to see even more, which is absolutely relevant and possible. Exception details You can register panels, which are just callbacks executed when an uncaught exception is […]

Entity Select-boxes & Nette

juzna.cz — Thu, 29 Dec 2011 11:00:34 +0000

Forms often contain a selection, e.g. when creating a user for in your app, you may need a role to be selected. If you use an ORM, you'd probably have IdentityEntity class in your app referring to an RoleEntity class. How will you create such a form? By adding plain select and converting Role Entity […]

Article::getClassName() or Article::className

juzna.cz — Wed, 28 Dec 2011 10:00:06 +0000

I miss a feature in PHP, which would allow me to reference classes easily. For example in Java, if you have a class cz.juzna.abc.Acticle and you want to give it to a variable/method, you can reference it by cz.juzna.abc.Acticle.class. In PHP, this can be done only by a string with class' name („cz\juzna\abc\Article“), which is however […]

Data binding in Nette Forms

juzna.cz — Tue, 27 Dec 2011 14:30:28 +0000

A form in your app sometimes match exactly to fields of one entity, but it's not always the case. This data-binding should be more general, e.g. one form can provide editing of a hierarchy of entities at once. And it should be bi-directional, pulling data from model and also storing it back. Usually you need to write lot's of […]

Abstract properties

juzna.cz — Thu, 15 Sep 2011 11:12:06 +0000

I hope you know you can declare classes and methods as abstract in most programming languages (including PHP) and if you write high quality object oriented code, I guess you use them quiet often. There is no discussion if they're good or not (at least I hope; and I'd like to hear your opinions). But what about abstract […]

Optimizing class cache in PHP

juzna.cz — Wed, 07 Sep 2011 22:40:15 +0000

Some time ago I read an article about hacking PHP internals to improve its performance. I liked the idea of avoiding unnecessary syscalls, because context switching is considered to be quiet expensive operation. And I realized there is quiet significant amount of work which needs be performed with class autoloading. So I decided to hack it and make it […]

Stealing Ruby’s yield for PHP

juzna.cz — Fri, 05 Aug 2011 09:00:56 +0000

I tried to learn Ruby once because it's so popular and cool these days. But I must admit, I didn't like it much. You may think I'm kinda oldschool, but having quotation or exclamation marks in method names is just not for me. And letting anyone to modify methods in previously defined class is the kind of thing I will […]

Weak references in PHP

juzna.cz — Wed, 03 Aug 2011 19:12:19 +0000

Today was created a new PECL package, which brings weak references to PHP. Weak references had already an RFC asking for their support in coming PHP 5.4, which was however not very perceived by PHP core developers. As they suggested, such a new feature which doesn't need changes in Zend Enginge (backend of PHP) should […]
