I have several Mako templates in my project that are named things like header.html.tmpl and settings.py.tmpl. I would like to add file associations to Eclipse to open these with the appropriate editors. For example, I would like header.html.tmpl to be opened in the HTML editor, settings.py.tmpl to be opened in the Python editor, etc. I go to Preferences->File Associations and I try adding *.py.tmpl to the list but after I click “Ok” nothing happens and the desired extension does not appear in the list. If I try instead using .py.tmpl I can add it to the list and add the Python editor to its associated editors but when I double-click a .py.tmpl file it doesn’t use the correct editor.

Obviously it would probably work to just use -tmpl instead of .tmpl, but I’m wondering if anyone knows a way around this or can confirm that it’s a bug/missing feature.
