Replace the Swift site generator with a Ruby and Phlex implementation. Loads site and projects from TOML, derive site metadata from posts. Migrate from make to bake and add standardrb and code coverage tasks. Update CI and docs to match the new workflow, and remove unused assets/dependencies plus obsolete tooling.

*Update: This has <a href="http://www.php.net/~derick/meeting-notes.html#late-static-binding-using-this-without-or-perhaps-with-a-different-name">been discussed</a> and will be uh, sort of fixed, in PHP6. You'll be able to use static::my_method() to get the real reference to self in class methods. Not optimal, but still a solution I guess.*

As colder on ##php (freenode) told me today, class methods in PHP don't have what they call late static binding. What's that? It means that this code:
|
|
|
|
```php
|
|
class Foo
|
|
{
|
|
public static function my_method()
|
|
{
|
|
echo "I'm a " . get_class() . "!\n";
|
|
}
|
|
}
|
|
|
|
class Bar extends Foo
|
|
{}
|
|
|
|
Bar::my_method();
|
|
```
|
|
|
|
outputs "I'm a Foo!", instead of "I'm a Bar!". That's not fun.
|
|
|
|
Using <code>__CLASS__</code> in place of <code>get_class()</code> makes zero difference. You end up with proxy methods in each subclass of Foo that pass in the real name of the calling class, which sucks.
|
|
|
|
```php
|
|
class Bar extends Foo
|
|
{
|
|
public static function my_method()
|
|
{
|
|
return parent::my_method( get_class() );
|
|
}
|
|
}
|
|
```
|
|
|
|
I was told that they had a discussion about this on the internal PHP list, so at least they're thinking about this stuff. Too bad PHP5 doesn't have it. I guess I should just be glad I won't be maintaining this code.
|
|
|
|
The resident PHP coder said "just make your code simpler", which is what I was trying to do by removing duplication. Too bad that plan sort of backfired. I guess odd things like this are where PHP starts to show that OO was tacked on as an after-thought.
