|RE: [pdt-dev] file with no extensions|
There is already an open bug  under the Eclipse platform relating to this issue, meanwhile you can use this trick  to work-around it.
I am trying to get syntax coloring and indexing working with files that don't have an extension. I have searched through the bugs, but couldn't find anything. Maybe I missed it.
I tried following the steps here, but got the same result as the top answer. Is there a bug open on this? If not, should I open one?
