Steve: Return type hints

nospam@example.com (Steve) — Sat, 07 Jul 2012 23:16:16 +0200

Its funny that your example uses std::string beuscae it has the solution you're looking for.What you're trying to do is initialize a class member before initializing the base class, and you found that you can't. The typical way to get around this is to abandon hope of extending Foo and implement the wrapper in terms of Foo. (has-a vs. is-a) This solution has the annoyance of you needing to redeclare each and every method you want to use and then forwarding those calls to Foo, and you won't be able to use a FooWrapper in place of a Foo as well, meaning you may need to change a ton of references in your code. However, all you have to do is have FooWrapper expose its underlying Foo and you're good. (kinda like what string::c_str() does)Check out your copy of Effective C++. From the TOC I think item 40 discusses this.

Iwona: How to get a Singleton right

While it's interesting to see all the dfirefent hoops one can jump through to accomplish this, I'm confused as to why would you want to make this particular bit of code more generic. Part of my difficulty arises from your initial statement: I often need to access the current class, for example for logging purposes. When you're doing this in a static context, you don't want the current class in the sense of the class in which this code is currently running ; instead, you want the class this code was written in (you called it Foo, above). getClass(), as in your original bit of code, is going to give you the Class object corresponding to the object that's actually instantiated at runtime, not necessarily the Class object corresponding to Foo. If you want a logger for Foo, specifically (as opposed to child classes of Foo, etc.), you can't use getClass() even in a non-static context (unless Foo is final).In a static context, you always know which Class object you want at the time you're writing the code. The .class construct exists in Java precisely to allow you to statically obtain a reference to a Class object using it not only avoids instantiating unnecessary objects (and creating unnecessary classes), but also seems, to me at least, to be much more readable and understandable (in terms of determining programmer intent) than the other options presented. It is almost certainly also faster, but that's probably negligible.

So auf Anhieb sehe ich nichts, evtl. zwei Dinge:
- Das Werfen einer Exception aus dem stream wrapper heraus versuche ich immer zu vermeiden.

- Das Verschieben des eigentlichen Ladens auf den Zeitpunkt des "echten" Zugriffs könnte ggf. ein Problem sein. Wie wird signalisiert, wenn es zu diesem Zeitpunkt ein Problem mit dem Zugriff gibt?

Ahoi,

nen bissel am thema vorbei .. naja halb .. aber ihr seit ja userland php stream wrapper experten. ich habe das ganze noch nicht im detail studiert, aber ein kollege hat regelmaessige seg faults auf den stream wrapper in jackalope zurueck gefuehrt:
https://github.com/jackalope/jackalope/blob/master/src/Jackalope/BinaryStreamWrapper.php

vielleicht faellt euch da auf den ersten blick auf falls wir da was "dummes" tun.

Sure traits are going to make their way in. 5.4 alpha now supports traits.

Rasmus Schultz: My wishlist for PHP 6, pt3: Annotations

nospam@example.com (Rasmus Schultz) — Wed, 18 May 2011 14:19:35 +0200

I love annotations! This post was one of the many I referenced early on, when I started designing my own library.

In my opinion, the mistake made by you and countless others, is to invent new syntax. Although your syntax is closer to standard PHP-DOC syntax than some libraries, you've added custom syntax for properties and values.

PHP has (familiar and readily available) syntax for that already. Okay, so you saved a few keystrokes - but you lost all of your standard PHP language features. The only new syntax you should need, is @name... everything you're trying to do between the parentheses, PHP already has syntax for - and the rest is PHP-DOC, an already well-defined, widely accepted and broadly supported standard, plus a pair of parentheses.

Have a look at my project's Wiki for more information:

Hello PEM,

as you might guess from the long time since your comment I'm currently very busy and didn't had any time to check the issues. I'm very sorry, but I hope to get back to vfsStream in the near future.

Rasmus Schultz: State of annotations in the PHP world

nospam@example.com (Rasmus Schultz) — Tue, 17 May 2011 00:57:15 +0200

I've released my own annotation framework for PHP, and it is now stable - have a look:

http://code.google.com/p/php-annotations/

It's early days for this project still - although the framework itself is stable and complete, there is still a lot of documentation to be written, and I am planning a library of standard annotations.

There is no place for discussion yet, but you're welcome to submit bug reports, or comment via email.

Thanks!

Hello Frank,

Any news on the matter ?

Marcelo Gornstein: State of annotations in the PHP world, revisited

nospam@example.com (Marcelo Gornstein) — Mon, 14 Mar 2011 13:14:08 +0100

Hello,

I've made an experimental patch to ZendEngine/PHP (5.3.5) to allow native annotations in the PHP language, the code can be found here: https://github.com/marcelog/AnoForPHP

It allows 0 or more annotations (without the use of DocComments) with 0 or more arguments themselves, in classes, methods, properties, AND arguments for methods, i.e:

/*
* The token chosen is "@@" because "@" was already taken.
*/
@@Annotation(key="value1")
class A {
@@Annotation(key="value1")
private $property;

@@Annotation(key="value1")
private function aMethod(@@Annotation(key="value1") @@Annotation2 $a, $b) {
...
}
}

I plan to use this same patch for Ding, which currently supports annotations but from standard doc block comments.

Regards!

Surely that gives you a better interface.
