No Syntax coloring when opening a file with custom editor [message #333270]

I have been updating a custom editor (cmakeed.sourceforge.net) and all
is generally going well except I have a small stumbling block.

My editor opens files with a name of "CMakeLists.txt" and "*.cmake". I
have a few projects where I have template files with names like
CMakeLists.txt.in and Project.cmake.in.

I can right click on the file in the project explorer and select the
"Open With..." menu which brings up the list of available editors. I
select CMakeEd and an editor opens BUT I have no syntax coloring or any
other custom feature that I wrote. The issues seems to be when I hit
the "createEmptyDocument(IFile) method in the
ResourceTextFileBufferManager class.

The line:

final IDocumentSetupParticipant[] participants=
((ResourceExtensionRegistry)fRegistry).getDocumentSetupParti cipants(file);

will

return a zero length array. I am assuming because it looks at the
extension points for my custom reader (among others) and decides that
the file name does not match what is in my extension point and so
returns nothing.

So my question: How do other editors handle this? I know I have had
instances where I have opened a file like source.cpp.in as a C plus
plus file and gotten the correct coloring, highlighting and all that.

Thanks for any help

Do something like that:

IDocumentProvider provider= new TextFileDocumentProvider();
provider= new ForwardingDocumentProvider(yourPartitioning, new
YourDocumentSetupParticipant(), provider);
setParentDocumentProvider(provider);

Awesome.. Thanks.. But I am still a bit "wet behind the ears" with this
so just _where_ would I put this code?

Thanks

This needs to be in the constructor of your own document provider.

Ok. I put that in the Constructor of my "CMakeDocumentProvider" class.
I also had to change the CMakeEditor class to extend from
AbstractDecoratedTextEditor. Things still seem to work with regard to
all the other behaviors. I still have the same problem at the same line
as my original posting.

final IDocumentSetupParticipant[] participants=
((ResourceExtensionRegistry)fRegistry).getDocumentSetupParti cipants(file);

will

return a zero length array so the participant.setup(document); line
will never get called.

I am sure I am just missing something hopefully obvious.

Thanks for the help

Got it!!. In the constructor for CMakeEditor I put the following:

IDocumentProvider provider= new TextFileDocumentProvider();
provider= new
ForwardingDocumentProvider(UIPlugin.CMAKE_PARTITIONING, new
CMakeDocumentSetupParticipant(), provider);
setDocumentProvider(provider);

And now things work as hoped/expected. THANKS!!.
