Hi All,
I have been reading lots on the CompareUI and have used it successfully
to implement a basic compare editor. However now I need to add code/syntax
colouring to my editor! The files I am comparing already have syntax
colouring in their editors but when viewed in the Compare Editor they look
like just plain text with not syntax colouring. Do I need to provide my own
editor instead of using CompareUI.openCompareEditor(..) in order to achieve
syntax colouring or can I somehow plug my own editor into the CompareUI
etc?? (I'm new to this!)

I have also looked at ResourceCompareInput but cannot see how it handles the
syntax colouring.

Can anyone provide me with some info on this and what I may need to do?
Thanks!

You'll need to create your own contentMergeViewer. Here are the set of
steps to create your own content merge viewer:

1) Add extension for org.eclipse.compare.contentMergeViewer. This allows
you to register a view factory (IViewerCreator) for creating a subclass
of TextMergeViewer. The association is by content type or file extension.
2) In your subclass of TextMergeViewer you'll need to override
getDocumentPartitioner/getDocumentPartitioning. You should use the same
partitioner you use for your editor. You will also need to override
configureTextViewer to provide a source viewer configuration (again, the
same one you use for your editor should work).
3) You may want to provide token comparator for breaking a line into
tokens (override createTokenComparator).

Hope this helps,
Michael

Thank you for that. It is nice to read a set of steps because after reading
the API stuff I was still none the wiser on the actual flow of things and
which components to use! Learning about all these plugins is not easy due to
lack of concrete examples etc. I'll give it a go.

Just one question from what you mention below:
"The association is by content type or file extension" => The stuff I am
comparing is not file based so extension is not possible. How do I specify
contentType? I am concerned (after reading up on contentType) that I may not
be able to use the contentMergeViewer plugin because I am not comparing
'files'!

Can anyone verify this please?

I am trying to display a basic TextMergeViewer but am having problems doing
so! Maybe I am not getting the big picture here but can someone please fill
me in on how to get the basics up and running!

I have a CompareItem which implements IStreamContentAccessor, ITypedElement

Then my ActionDelegate class has the following:

CompareItem left =
new CompareItem("Left", pou1);

CompareItem right =

new CompareItem("Right", pou2);


IWorkbenchPage page =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage();

TextMergeViewer tmv = new TextMergeViewer(page, new CompareConfiguration());

tmv.setInput(new DiffNode(left, right));

The TextMergeViewer is not being displayed! Any help would be appreciated!

You can associate a type with an element using the
ITypedElement.getType() method. So, for example, you can decide for type
is "BLAH". Then getType should return blah and you shoudl associate your
merge viewer with BLAH as well (i.e. the type is usually a file
extension but doesn;t need to be).

To actually get the merge viewer to appear, you would want to make use
of a CompareEditorInput. In the prepareInput, you should prepare and
return your ICompareInput. The CompareEditorInput then takes care of
finding an appropriate viewer. You can host the editor input in an
editor by calling CompareUI#openInEditor.

After some thinking and stepping back from the problem to try and see the
big picture I got it working!

I was having problems trying to understand the actual link between providing
my functionality and where it hooks into the functionality provided by the
contentMergeViewers plugin!

But now I understand (for now anyway!)

Thanks for your great feedback.
Glenn.
