GNTP Image URI in Growl 1.3

[geetarista]

I'm confused as to why GNTP says the following:

The +icon+ map be an image (anything NSImage supports) or a URI (which is unsupported in growl 1.3).

because it seems to be supported in the documentation: http://growl.info/documentation/developer/gntp.php.

I've been trying to figure out how to get this to work, but as far as I can tell, the comparison URI === icon never works.

Am I missing something or does the code need to be changed?

When I was discussing this with the growl developers on IRC they said that URL icons had been disabled in the source for growl 1.3. You'll need to wait until the growl developers re-enable images sourced from URLs for them to work. I didn't ask why they were disabled.

If you run in ruby debug mode you'll see that the icon URL is sent:

$ ruby -dIlib -rruby-growl -e 'g = Growl::GNTP.new "localhost", "test"; g.add_notification "test", nil, URI("https://secure.gravatar.com/avatar/58479f76374a3ba3c69b9804163f39f4"); g.register; g.notify "test", "test"'Exception [snipped warnings and caught exceptions]

Weird that they'd do that. So what's the best way to pass in a file then? I see you passing in straight data, but how can I pass in a local file? I tried several different ways but couldn't get anything to work. I'm trying to get an implementation going to have ruby-growl as a notifier for guard.

Appreciate your help, Eric.

Adding code to ruby-growl to fetch images from URLs and send the raw image data would be a nice workaround. I'll see what I can do.
