# Reports whether the *presence-detect daemon* is currently holding the idle
|
|
# inhibitor (i.e. the camera saw motion and is auto-keeping the screen awake),
|
|
# as opposed to a manual caffeine toggle.
|
|
#
|
|
# The lock is shared with caffeine.sh, so PID_FILE alone can't tell the two
|
|
# sources apart. OWNED_FLAG is touched only by presence-detect.sh when it starts
|
|
# the inhibitor and cleared by both a manual caffeine toggle and the daemon's
|
|
# own release — so "PID alive AND OWNED_FLAG present" uniquely means the daemon
|
|
# owns the lock right now.
|
|
#
|
|
# Prints "true" when presence-detect owns the lock, else "false". Used by the
|
|
# Eww caffeine widget to highlight itself in the Active Hot Pink accent.
