Currently eclipse only supports wildcard prefixes for content types and file associations (e.g *.xml). It needs to be able to handle wildcard suffixes as well so if you have a file format that has a fixed prefix but not suffix you can add it as a content type or file association (e.g. Makefile.*).

The best (if implementation would be possible) would be to check filenames by the standard regex pattern(s) to define associations. This would allow for all the imaginable combinations to get configured properly. Upvoting the solution. Just for reference, this would solve bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=292229 too.
I'd like to see this added for 4.8. I'm assigning this to myself so it shows up in my todo list, but if anyone is also interested, I'd be glad to change assignment so it goes to the first one able to fix it.
The entry points to add this would be: * org.eclipse.ui.internal.registry.FileEditorMapping (and probably interface IFileEditorMapping to add a new method, but it's no API issue as it's mark as @noimplement) * org.eclipse.ui.internal.dialogs.ContentTypePreferencesPage.Spec to add the regexp as a field Then everything that reads the name or the extension of those 2 classes sould be augmented to also read the regexp, and the FileExtensionDialog should allow patterns It does seem like a too hard piece of work to do.

Will the pattern matching associations have a lower priority compared with the perfect match associations?
Tentative for 4.8.M2. I've started to work on a patch and I believe it should be ready next week (too late for 4.8.M1)

I am trying this pattern-based content-type definitions at the moment and I am running into problems. When I define: <file-association content-type="org.springframework.boot.ide.properties.application.properties" file-names="application.properties"> </file-association> The file called "application.properties" gets this content-type and the associated editor/icon shows up in the package explorer. If I instead define: <file-association content-type="org.springframework.boot.ide.properties.application.properties" file-patterns="*application*.properties"> </file-association> The associated editor/icon doesn't show up, looks like this content-type gets ignored for a file called "application.properties". When I debug into ContentTypeCatalog.internalFindContentTypesFor, it finds the regexp-based content-type, but it is not used later, looks like the extension-based content-type that matches here (for Java properties) is selected instead. Is there a way to get my regexp-based content-type association being selected instead of the Java properties type?

Did you mark you content-type as extending JDT properties content-type? I think it's necessary if you want to make sure it's going to be the one returned as IIRC the ContentTypeManager returns the "most specialized" one in case it finds multiple content-type. If you don't define you type as extending base properties type, then it doesn't seem more specialized and the ContentTypeManager may return one or the other, and would be right for both.
Good point. I changed this, but my content type still isn't being selected. Here is the full extension declaration: <extension point="org.eclipse.core.contenttype.contentTypes"> <content-type id="org.springframework.boot.ide.properties.application.properties" base-type="org.eclipse.jdt.core.javaProperties" name="Spring Properties File" priority="high"> </content-type> <file-association content-type="org.springframework.boot.ide.properties.application.properties" file-patterns="*application*.properties"> </file-association> </extension> Any idea what might be going wrong here?
