Subject: [PATCH BlueZ v2 1/4] client/main: add help option for available args
Date: Fri, 16 Aug 2019 23:34:49 -0700
Message-ID: <20190817063452.23273-2-rpigott@berkeley.edu> (raw)
In-Reply-To: <20190817063452.23273-1-rpigott@berkeley.edu>

From: Ronan Pigott <rpigott@berkeley.edu>

This option exists to facilitate external completion of commands that
have specially defined arguments. It effectively adds two new commands
to bluetoothctl with the following output:

$ bluetoothctl agent help
on
off
DisplayOnly
DisplayYesNo
KeyboardDisplay
KeyboardOnly
NoInputNoOutput

$ bluetoothctl advertise help
on
off
peripheral
broadcast

Shell completion scripts can then parse this output to provide
completions for those commands.
