Greetings,
I am writing an Eclipse plugin, namely a text editor for a certain
document type we have developed. I am trying to add the familiar red
squiggly marks in the text, but I do not know how. I have read
http://help.eclipse.org/help21/index.jsp?topic=/org.eclipse. platform.doc.isv/guide/editors_annotations.htm,
but it does not help much. I suppose I will need to add a
DocumentListener to listen for changes in the document, then parse the
text and add/remove/update the squiggly marks if needed.
How do I add/remove/update the squiggly marks, if I know already where I
want them?
Thank you in advance,
Martijn van Steenbergen.

If you want the error to also show up in the Problems view, you can simply
create a marker on that resource of type IMarker.PROBLEM (see
IResource.createMarker()). If you do not want it to show up in the
Problems view, you can define your own marker type (or use IMarker.TEXT)
and then specify how it should be annotated by adding markup in your
plugin.xml. Search the help contents for markerAnnotationSpecification
for more on that.
Hope this helps,
Ryan

Daniel, Ryan, thank you for your replies. Your replies bring up some
more questions:
- I am now keeping my model in my ContentOutlinePage's ContentProvider.
Should I move it to the SourceViewerConfiguration's Reconciler? If not,
what is the usual place to keep the model?
- How does the model report the temporary problems that cause the
annotations to be displayed?
- What is the appropriate place to set the problem markers? My guess is
to override TextEditor.doSave(), check the model for errors, then set or
clear markers if necessary.
Thank you very much in advance,
Martijn van Steenbergen.

Please ignore my three previously asked questions. I have already solved
parts of my problems.
It seems that all the problems, including the temporary ones, are
signified using markers. Now I know this, it is easier to find
documentation for the markers. The documentation I have found so far are
pages in the Eclipse help files and an article at eclipse.org.
I have moved my data model to my TextEditor. My Reconciler tells the
TextEditor to reparse the Document's contents, and my TextEditor passes
the newly created data model to the ContentOutlinePage and its TreeViewer.
I have overridden the TextEditor's editorSaved() to clear old markers
and create a new one in case of a parse exception. The problem marker
appears immediatly in the Tasks View, but I have to reopen the document
in my editor to cause the red squiggly thingies and the red cross in the
vertical ruler on the left to appear. How do I tell the text editor I
have changed my just created problem marker's attributes so that the
squigglies appear right after saving?
This still leaves the temporary problems unhandled. Just like in the
Java editor, I would like temporary problems to be marked using
squigglies, but not yet appear in the Tasks View. Is creating my own
marker type(s) and/or manipulatin the plugin.xml file the only solution
to this? If not, what are the other solutions?
I thank you very much for your time.

I don't know that there is a "usual" place to keep the model, just make
sure that the model is accessible from both the reconciler and the content
provider. I think that the jdt makes its model accessible from the
document provider.

The reconciler will reparse the document and compute any syntax errors.
This can be done any number of ways. As you parse, you can report the
problems as you encounter them or queue them up until you've finished
parsing. Either way will work.

I would suggest creating a builder for your resource type. This will be
more consistent with the workbench, and will automatically hook into the
incremental builder and other things for you ('clean', for instance).

Never mind, solved these problems too :D
The trick was to update the just created markers in a IWorkspaceRunnable.
Thanks a lot for your help!
Martijn.
