| Get Project Properties in ContentAssistProcessor [message #225808] |

Hi there,
I implemented a little plugin to extend content assistance and
validation for HTML files. Everything works fine so far: I extended
StructuredTextViewerConfigurationHTML and returned my own
ContentAssistProcessor.
However, the possible proposals are dependent on some project specific
properties (at least in some cases). I understand how to store these
properties on the project resource, but I don't know how to get to the
IProject resource from my ContentAssistProcessor. In
IContentAssistProcessor.computeCompletionProposals there is a
ITextViewer object and in my
StructuredTextViewerConfiguration.getContentAssistProcessors a
ISourceViewer object as parameter, but I don't see a way to get to the
project resource from there. Can anybody help?
Thanks in advance and a happy 2009,
Dominik

Just in case anybody has found this thread while googling for an answer
to a question similar to mine:
I found a way to get the actual file of a IDocument (if there is an
associated WST model). I can't remember where I found the code, I think
it's from a Spring Plugin. You can easily get the project afterwards by
calling the getProject() method of the file afterwards. I don't know
whether it is the best way, but it seems to work. So here we go:
public static final IFile getFile(IDocument document) {
IFile resource = null;
String baselocation = null;
if (document != null) {
IStructuredModel model = null;
try {
model = org.eclipse.wst.sse.core.StructuredModelManager
..getModelManager().getExistingModelForRead(document);
if (model != null) {
baselocation = model.getBaseLocation();
}
} finally {
if (model != null) {
model.releaseFromRead();
}
}
}
if (baselocation != null) {
IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
IPath filePath = new Path(baselocation);
if (filePath.segmentCount() > 0) {
resource = root.getFile(filePath);
}
}
return resource;
}
