How does Growl invoke the ~/Library/Application
Scripts/com.Growl.GrowlHelperApp/Rules.scpt file? Notwithstanding the ".scpt"
suffix, it works fine if Rules.scpt has plain text AppleScript in it; but if it
could have a "compiled" script in there instead, anything listed by osalang
could be used; for Yosemite and later, that includes JavaScript.
And that doesn't even count having the script use "do shell script" not only to
take some unusual action, but by passing the interesting properties of the
notification, give the script some ability to choose what to do about it.
Quoting the properties safely yet keeping them separate while passing them
might be a tricky proposition, and not one I wish to explore right now. :-)
What are examples of what the "note type" property might have in it, anyway? I
don't see that field shown in the history, and didn't need it in this case, so
I didn't fool with a temporary script just to see what all the properties
looked like.
One more question: if I want to modify a property (the note description, in
what I have in mind, by appending some text to it), do I have to explicitly
return the notification, or will the default behavior see the change? I saw an
example of doing things when switching to battery power, and I think I can hook
in some code that, when AC is removed, checks if a backup is running, and if
not, ejects the backup volume (if it's mounted). If a backup _is_ running, I
may want to append "\r Note: cannot auto-eject backup volume" to the
notification text for going on battery; otherwise, I ought to generate an
additional visual indication ("display alert", or can I send an additional
notification within the rules script, without messing up the notification I'm
responding to? and wouldn't I have to make up a bogus application name for
that?").
