HelloDevice is a simple daemon that sits and monitors X11 input devices. Whenever a device is enabled or disabled, it executes the command configured by the user for this device, passing in the device name and device ID. The custom command may then be used to e.g. set up a specific keyboard layout for this device.
The external program is executed as follows
$ custom-command -t [added|removed|present] -i <device ID> <device name>
Where added means a device has been added, removed means a device has
been removed, and present means the device was already present when
HelloDevice started up. For obvious reasons, you can only get present
immediately after startup.
The device ID is the X11 device ID as returned by e.g. xinput list. Note:
the X11 device ID is not the same as the /dev/input/event device node
number.
The device name is the X11 device name as returned by - you guessed it -
xinput list. Note: the X11 device name may not be the same as the
kernel device name although on most systems for most devices it is
the same.
Configuration lives in $XDG_CONFIG_HOME/HelloDevice/HelloDevice.conf.
$XDG_CONFIG_HOME usually resolves to $HOME/.config.
This directory will be prepended to $PATH, so feel free to drop any
configuration scripts in there.
The configuration file looks like this:
[General]
command=/path/to/command
Yes, exciting, isn't it? More features to follow, maybe, some day.
Make sure the command is executable.
