I try to create a text editor with IMP, and generally I like the system.
My most serious problem with it is that the error messages of the parser appear only as annotations together with the source, but not in the problems view.
I looked at the "Editor annotation creator" wizard as it seems to be doing what I need, but it uses an undefined extension point, so it doesn't work.
I didn't find any obvious way to create these markers in a programmatic way as I couldn't get any reference
Can you help me how to create the specific markers needed for Problems view?
Thanks for your response,
Zoltán Ujhelyi

Hi there,
[Somehow Thunderbird didn't show me this message, even though I've been
checking the newsgroup every so often... sorry!]

Generally, the messages found in the Problems view are created by an
incremental builder. Basically, they're just markers (cf. annotations)
placed on workspace resources (usually files).
To see how that's done, look at the method createMarker() on the class
BuilderBase.
Technically, there's nothing preventing your parser (or IMessageHandler
implementation) from doing that, but you have to be careful to delete
old markers before adding new ones when you re-parse.
Hope that helps...

Thank you for your answer.
I knew how to create error markers, only I could not find where to do this.
I looked again into the code, and found where to add new MessageHandlers to the system, and there I could solve the problem.
On the other hand, can you tell me, what does (or should) the "Editor annotation creator" extension point do?
Thank you again for your help,
Zoltán Ujhelyi

You don't need one - it's an optional service. It's a relatively general-
purpose hook for you to add other kinds of annotations to your editor,
usually based on the content of the file's AST. I *think* we've used it
to create annotations from "TODO" comments. *I think*.
Hope that helps!

Thanks for your quick answer. I think, that extension point could be useful - for similar reasons you listed, but it is not working - only there is a wizard for creating one.
I suggest either removing that wizard or (re-)adding that extension point.
Thanks,
Zoltán

Hmmm... Can you post a bug report on bugzilla?
