Enhancing the JDT Java Editor [message #324701]

Hi,

Is there anyway to modify the default Eclipse Java Editor programmaticaly? I can't seem to find any extensions that support the extending of the JavaEditor class.

For example, if I want my plug-in to change the color of comments in the Java editor from green to yellow, can it be done?

Cheers.

Shane,

Go crazy with Window->Preferences->Java->Editor->Syntax Coloring

Perhaps I wasn't very clear in my request. I want to actually add functionality to the default java editor. The color change was just an example.

Here's a better example: I want the Java editor to automatically change any text in between two ampersands (&...&) to yellow. Is there any way I could add this feature? It would require somehow accessing the SourceViewerConfiguration.

Shane,

It's not a very good example then. :-P

I don't think the Java editor has APIs to would let you arbitrarily
change the colorization algorithm. Of course it's open source, so you
could change the base code...

Ah I see. Thanks for that.

And in defense of my initial example, the first sentence of my post should have made it quite clear that I wasn't asking merely for directions to the customization menu.

But that's all good. :P

Nice answer, Ed :-)

But I think Shane is asking about doing it programmatically. With regard to
the color of comments (or anything else that can be modified through the
preferences dialogs), one answer is simply to change the preference
programmatically, that is, using the Preference API - see
http://www.eclipse.org/eclipse/platform-core/documents/user_ settings/faq.html .

Shane, if you want to do something that is not covered by changing settings,
please be more specific.

Sorry, in the time it took me to respond, I see that you did clarify some
more.

Yes, if you want to actually change the syntax coloring algorithms, there's
not going to be a simple answer.

I would suggest looking at the Structured Source Editor, which is part of
WTP.
