Subject:  [pdt-dev] Shaving of keystrokes: extension points?

§ 1. Is the documentation on pdt extension points outdated?  

AD: Yes ;(


-------------------------------------------------------------------------- 

I tried to implement the sample Code assist strategy [1]. I have the following observations: 

1. The code contains an error (XYZCompletionContext contains superflous brace). 
2. The last modification date of the extension help [1] is 2 May 2014 
3. I get a lot of warnings like 

    Discouraged access: The type 'CodeCompletionRequestor' is not API 
        (restriction on required library '/home/xyz/eclipse/agents/standaard/pool/ 
        plugins/org.eclipse.php.core_4.0.1.201606232253.jar') 

Most of current extension points require you to use *.internal classes so it’s not API in Eclipse mean. We working to clean this up, but for now you can just ignore such errors.


4. The XYZCompletionContext sample [1] doesn work correctly as it breaks the auto-completion 




§ 2. What I want to achieve 
-------------------------------------------------------------------------- 

In php-method context I want to automatically rewrite 

    var = 

into 

    $var = 

I also want to give autocompletion for "var" as variable, eventhough it is not prefixed yet with a dollar. 


What extension points would I need to achieve this? 

AD: It depends when should this happen? After ctr+space as a suggestion, as quick fix/quick assist (ctrl +1), during. For ctrl+space or ctr+1 suggestions you should use one of PDT extension point, to force autochange on enter/space directly, WTP SSE autoedit extension point will be requiredand PDT >= 3.5 : https://bugs.eclipse.org/bugs/show_bug.cgi?id=460546
