How to implement directory independent extensions ¶

Many people want to use downloaded extensions in their own way. As for me most of the extensions require me to correct Yii::import() instructions inside their source code. All these extensions are directory dependent. To avoid the situation described above, I suggest to implement pseudo-anonymous aliases:

// take the current extension path
$dir = dirname(__FILE__);
// generate alias name
$alias = md5($dir);
// create alias
Yii::setPathOfAlias($alias,$dir);
// import other classes
Yii::import($alias.'.anotherClass');
Yii::import($alias.'.andAnoTherClass');
//...
//if you want, you can destroy an alias created
Yii::setPathOfAlias($alias,'');

Using this technique you can create really directory-independent extensions.

@Yeti

I think there is no need to modify Yii::import(). You can write simple helper to yii.

Correct code

Dohhh!!

public static function import($alias,$forceInclude=false,$baseDir='')
{
  if($baseDir)
  {
    $pathAlias=md5($dir);
    Yii::setPathOfAlias($pathAlias,$baseDir);
    $alias="pathAlias.$alias";
  }
 
  // Current Yii::import code
}

Include in Yii core

Brilliant!!

Perhaps Yii::import could be modified to include this feature

Something like

public static function import($alias,$forceInclude=false,$baseDir='')
{
  if($baseDir)
    $alias=md5($dir).".$alias";
 
  // Current Yii::import code
}

then extensions can import with

Yii::import('Class',false,dirname(__FILE__));
