detect invalid file?

[atlgeek007]

Is it possible to have taglib-ruby raise an exception if it is not passed a valid file?

I'm trying to write a script to automate renaming/moving files from a download folder into my music hierarchy, but the script tends to exit ungracefully when faced with an invalid file, and it doesn't seem to raise an exception that I can catch.

It will simply output TagLib: FileRef::tag() - Called without a valid file., which doesn't give my limited knowledge of Ruby anything to catch and do something more pleasant with.

You can check FileRef#null? before calling tag:

TagLib::FileRef.open(file) do |fileref|
  unless fileref.null?
    tag = fileref.tag
    # ...
  end
end

I documented it better, see above commits. Raising an exception is not something I want to add as I want to diverge as little as possible from TagLib.
