Determining editor file content [message #239837]

I have written a custom editor plugin as an extension to
org.eclipse.ui.editors for a proprietary script language so that I can
colourise the code. This works OK provided that the source files I am
editing have a file extension and I add this file extension to the
'extensions' property of my editor extension. Then any files with this
extension display my custom icon in the Navigator and when I right click
on such a file, my new editor appears as an option under the list
displayed by Open With - exactly as I would expect.

The problem I have is that I also require to be able to use this editor
with a set of existing files which do not have a file extension and it is
not possible for me to change the file names. Eclipse books that I have
read suggest that I could solve this either by specifying a
matchingStrategy class that implements IEditorMatchingStrategy or by
adding contentTypeBinding subelements pointing to my own content types and
implement an ITextContentDescriber class. I have attempted to do both of
these things but without success and trawling the Internet I have been
unable to find any examples of how to do this or any further information
other than that contained in the Javadoc.

Can anyone help by providing me some examples of either technique please?

Maybe you find some hints in the corresponding bug report:

Thanks for the suggestion but unfortunately this did not help. From this
bug report it looks as though it might still be an outstanding bug. Anyone
else got any ideas?
