Re: How can I create a filetype association that uses the filename's extension?

Ah. I don't think Nautilus has a GUI for this. You can do it
manually though, using the XDG MIME types system. If you like
reading specifications:

If you'd rather have the quick-and-easy version:

Create the folder .local/share/mime/packages in your home

Create a file in that folder with a .xml extension. Call it
"mymimetypes.xml" or whatever you like. Here's one I just made
to register a MIME type for Mallard page files:

<?xml version="1.0" encoding="UTF-8"?>
  <mime-type type="text/x-mallard-page+xml">
    <comment>Mallard Page File</comment>
    <glob pattern="*.page"/>

Change the type attribute to the MIME type you want. Change the
comment to whatever you want to see files of that type called
in Nautilus. Change the glob pattern to match the extension of
the files. You can have multiple glob elements for each MIME
type to use that type for any of the globs. You can add more
mime-type elements to mime-info to register more types.

Save the file, and run the following at the command line:

  update-mime-database  ~/.local/share/mime

Nautilus should pick up the changes immediately.
