Extending content assistance of WTP's XML editor [message #720904]

Wed, 31 August 2011 09:06

Hello,
I'm trying to develop an Eclipse plugin which will extend Web Tool's XML Editor's content assistance in order to allow auto-completion of attribute values in XML files (a modest goal to begin with..).

So I've created a plugin which extends

org.eclipse.wst.sse.ui.completionProposal

, and managed to get completion proposals working with my own simple and unfeatured proposal computer.
Thing is, I'm not very keen on implementing a whole XML framework to determine where in the XML document the content assist was invoked, especially when the following class exists:

org.eclipse.wst.xml.ui.internal.contentassist.AbstractXMLCompletionProposalComputer

Unfortunately, it's not an available for plugin developers to extend.

I found this bug directly relating to the subject:
http s://bugs.eclipse.org/bugs/show_bug.cgi?id=310696
(cannot post links yet..)

Is there maybe a better way to accomplish this? Or anyway around this issue till the "bug" is fixed?
And also, a patch was created to resolve the bug. The contributor mentions targeting for the next milestone suitable milestone. Is it reasonable to apply the patch locally and to start developing the plugin?

Would appreciate any input or help with the matter.
Thanks a lot,
Roded

I am working on the same subject.
What I did so far is to edit directly Eclipse source code...this is not the best choice of course, but if no API are available...

Hi Roded,

Unfortunately, the patch as it is still utilizes internal classes as parameters (org.eclipse.wst.xml.ui.internal.contentassist.ContentAssistRequest) so it can't be used as API. So the patch will need some more work. There aren't any real work arounds to utilizing the functionality without using internals at the moment.

Nick, do you perhaps have an estimation as to when the bug is planned for?

Thanks for the replies & the work.

Hi Roded,

The earliest we would be able to get to it is for Juno. You're welcome, though I wish I had better--or more--news.
