Hi,
yes, i've tried that, but the extensions array in the PHPIndexingVisitor
is private,
so i can't simply override the constructor and cast them to my own
Extensions.
This is the plugin.xml of my current implementation:
https://github.com/pulse00/Symfony-2-Eclipse-Plugin/blob/master/org.eclipse.symfony.core/plugin.xml#L63
I've created a patch though to pass the requestor over to the
PhpIndexingVisitorExtension (attached).
Couldn't find another way to actually add elements to the Sql Index.
Am i missing something?

hi Robert ,
Do you implement your own IndexingVisitor?
btw,does it make sense if we pass requestor(IIndexingRequestor) to
PhpIndexingVisitorExtension ?

sorry for spamming the list, but there's really not much
information in the net available concerning PDT indexing.
I've followed the "contributing to index" chapter in the wiki
http://wiki.eclipse.org/Extending_PDT_2.2#Contributing_to_index
but i'm not sure if this is still up-to-date, because when i
contribute additional fields to a TypeDeclaration,
nothing appears in code assist for $this-> in that class.
What confuses me is that a PDT Indexing Extension needs to
subclass PhpIndexingVisitorExtension
and provide declarationinfos using modifyDeclaration() calls.
However, the modifyDeclaration() method in the
PhpIndexingVisitorExtension is completely empty,
as apposed to the PhpIndexingVisitor which calls
requestor.addDeclaration(info) in this method.
The requestor is not available to extensions though.
My IndexingVisitor does basically the same like the one in the
Wiki (inside the endVisit(TypeDeclaration) method):
DeclarationInfo info = new
DeclarationInfo(IModelElement.FIELD,
Modifiers.AccPublic, start, length, start,
length, name,
null, null, namespace.getName(),
currentClass.getName());
modifyDeclaration(field, info);
Do i need to specify an implementation for the modifyDeclaration()
method in my indexer as well?
thanks!

Hi,
a lot of PHP Frameworks implement the MVC pattern, and i'm
wondering what's the
best way to provide codeassist for PHP variables in files that
have been declared
in other SourceModules.
Let's say you have the class UserController with the method
showUser() (in /UserController.php)
... class declaration
public function showUser() {
$user = UserDAO::retrieveUserByID($id);
return array('showUser.php', array('user' => $user'))
}
The framework then renders the file 'showUser.php' and passes
in the $user object
as a variable named $user.
What i have done right now is the following:
1. In the SourceElementRequestor extension i visit the
ReturnStatements of methods in Controller
classes.
2. I detect the variables returned by that method and store it
in some custom Singleton.
3. Register a completionContext/Strategy which retrieves the
correct variables for the current php file from the Singleton.
This approach works, though it doesn't feel properly
integrated into the DLTK/PDT model, as
1. I'm simply storing the ViewVariable in-memory in my
singleton, so after Eclipse relaunches, the whole project
needs to be rebuilt for completion to work.
2. I'm getting ConcurrentModificationExceptions in my
Singleton class during the BuildPhase as apparently the
SourceParsing
takes place in multiple threads.
So my question is, is there a way to contribute those
Variables which are being passed to the View-Templates
properly to the DLTK/PDT model ?
regards,
-robert
