This daemon makes it easy to organize ubus objects into a cleaner structure - much like sysfs filesystem and dbus. You can place all your ubus objects into /etc/ubus folder tree and access them through both symlinks and filesystem-like paths.

This allows you to write ubus objects in shell, C, lua or whatever else you want. Then you place them somewhere under /etc/ubus/ and reload the service and they will come up as ubus objects.

• Create a shell script in /etc/ubus/mynamespace/test

  #!/bin/sh

  if [ "$1" == ".methods" ]; then echo "test"; fi if [ "$1" == "test" ]; then echo "{"foo":"bar"}"; fi

• Make it executable (chmod +x ..)

• /etc/init.d/etc-ubus-daemon reload

• if you want, you can also create a symlink to your object

  (cd /etc/ubus; ln -s mynamespace/test link)

• ubus list -v /mynamespace*

  '/link' @1c6da7c7 "test":{} '/mynamespace/test' @ef4f806d "test":{}

You can now call these objects just like any other ubus object.

The .methods metamethod can either return a comma separated string of methods, or it can return a json object that looks like this:

{ 
	"method": { "param": "param_type" }
	..
}

This allows you to set let ubus know what type the paramteres should have. Valid types are:

bool
int
string
