There are at least three places in the current Squeak image where we deal with the types of media files:
- In FileLists, so that the fileSelected menu can be smart about what options to offer you.
- In Scamper, so that clicking on a link does the right thing.
- In PWS, so that the server returns the right MIME type for a returned file.
Perhaps this is two too many? :-) As I'm merging in various folks' code (in PWS, in images for my class, etc.), I'm fighting file type handling conflicts. The FileList>>itemsForFileEnding: method has six versions in the new image I just set up for my class!
I'm considering creating some kind of MediaType class that can be associated with file types and provide functionality for these various situations. I don't think it's enough to just do MIME, though MIME is a good subset or starting set. The problem is that we're also inventing new media types (like SqueakyPages), so I think we need a more flexible system.
Comments? Is somebody doing something like this already?
Thanks! Mark
