Well, to answer one of my own questions, here are what the properties look
like for a HardwareGrowler mount or unmount notification (omitting the
note icon, which I didn't think made sense to write out as text!) for
a volume in this case named "LaCie":
host: localhost
app name: HardwareGrowler
note type: VolumeMounted
note title: LaCie Mounted
note description: Click to open
sticky: false
priority: normal
host: localhost
app name: HardwareGrowler
note type: VolumeUnmounted
note title: LaCie Unmounted
note description:
sticky: false
priority: normal
Here's my script again, with the ability to, when AC power is removed,
auto-eject the backup disk if a Time Machine backup is not currently in
progress. The action to take if a backup IS running has not yet been
exercised. :-) (that relates to my other question: whether an explicit return
of the notification is needed to pass back a modified property - some help with
that please?)
The volume name is now in a variable; assuming a single external backup drive
on a laptop, this might work in other cases, by just changing the value of
backupVolume appropriately.
I _hate_ debugging AppleScript, it doesn't tell you where an error is, only
that there is one. I got around that with osascript -i and pasting in a single
line at a time; but there's got to be a better way (short of buying Late Night
Software's expensive script debugger). Still, once it's working, it's kind of
nice to just do one thing and have all the rote followup happen by itself. :-)
using terms from application "Growl"
on evaluate notification with notification
-- change value below as needed
set backupVolume to "LaCie"
set mountedMessage to backupVolume & " Mounted"
set unmountedMessage to backupVolume & " Unmounted"
if notification's app name equals "HardwareGrowler" then
if notification's note title equals "On Battery Power" then
set TimeMachineIsRunning to do shell script "tmutil status"
if TimeMachineIsRunning contains "Running = 0;" then
tell application "Finder"
if disk backupVolume exists then eject disk backupVolume
end tell
else
set alertMessage to ¬
"\rWarning: Time Machine backup in progress, " & ¬
"cannot auto-eject backup volume " & backupVolume & "."
set notification's note description to ¬
notification's note description & alertMessage
end if
else if notification's note title equals mountedMessage then
do shell script "sudo tmutil enable;sudo tmutil disablelocal"
else if notification's note title equals unmountedMessage then
do shell script "sudo tmutil disable;sudo tmutil disablelocal"
end if
end if
-- absent an explicit return, defaults are used
end evaluate notification
end using terms from
