Events & Parameters

Hedge defines 5 events:

Each event has its own set of unique parameters that you can use.
Do you need another parameter or event? Email us at and we'll check if it's possible.

If you have built a script please let us know so. We’ll feature your scripts, so that other Hedge users can benefit too.

Folders and Files in AppleScript
We're used to seeing paths delimited like URLs, with /. In Applescript though, paths are delimited with the colon (:) which is called POSIX. Hedge outputs URLs, so you'll need to convert to POSIX. Luckily, that's easy to do:

property theFolder : "{destinationPath}"

tell application "Finder"
   open (theFolder as POSIX file)
end tell

If you want to refer to your home folder, you can't just use ~. Instead, you need to insert the home folder path like this:

tell application "Finder"
   open (POSIX path of (path to home folder)) as POSIX path
end tell


  • Timestamps are shown as YYYYMMDDHHMMSS
  • Duration is in seconds, with six digit precision
  • Size is in bytes. To convert bytes to GBs divide by 1024^3. 

We added an extra layer of security: paths are event-specific, and include the event name. This way you can’t accidentally use your “Erase Source”-script to erase a Destination.

Fires when a new disk is mounted. Pretty self-explanatory.


Example Output

DiskAdded_title Disk A
DiskAdded_rootFilePath  /Volumes/Disk A
DiskAdded_diskSize 249779191801
DiskAdded_availableDiskSpace        61058125824
DiskAdded_protocolName USB
DiskAdded_mountedAt 20161125113059


Other bus *protocolNames* include Firewire, Secure Digital, iSCSI, SAS, afpfs, nfs, PCI, SATA and more. Disks connected through a USB hub all show up as USB drives, so you can't discern between true USB disks or Compact Flash media. A way around this is to check for diskSize.

Script: Keeping in the background


Fires when a transfer starts. A disk is either being imported, or being imported to. When Disk A is imported to Disk B and Disk C, three DiskBusy events fire.


Example Output

DiskBusy_diskType Source or Destination
DiskBusy_rootFilePath                       /Volumes/Disk A
DiskBusy_title Disk A


Fires when a single transfer is done, e.g. Disk A has been copied to Disk B. The transfer to Disk C might still be running!


Example Output

FileCopyCompleted_sourcePath /Volumes/Disk A
FileCopyCompleted_destinationPath    /Users/Hedge/Documents/Footage/Project-001
FileCopyCompleted_bytesCopied 16582836224
FileCopyCompleted_duration 693.357678
FileCopyCompleted_startedAt 20160129144109
FileCopyCompleted_verified YES or NO
FileCopyCompleted_state Success


There are four possible states when a transfer finishes:

  • Success: all went well
  • Failed: a file transfer failed
  • Warnings: verification of a copied file failed
  • Cancelled: the transfer was cancelled by the user

Script: Email me when a transfer fails

Fires when a disk is done with whatever job it was doing.


Example Output

DiskIdle_title Disk A
DiskIdle_diskType Source or Destination
DiskIdle_hasFailedTransfers                 YES or NO
DiskIdle_rootFilePath /Volumes/Disk A


Script: Email me when I can swap disks

Fires when a disk is removed from the system. Maybe it was ejected in Hedge, or in Finder, or simply removed manually.


Example Output

DiskRemoved_title Disk A
DiskRemoved_rootFilePath /Volumes/Disk A
DiskRemoved_unmountedAt                20160129144109
