HGreet.Client

To use this module, first get the path to the socket of the greetd daemon from the environment variable GREETD_SOCK. This requires the greetd daemon to be running. Then you can communicate with greetd using the withSocketDo function of this module, passing it a callback function that will have direct acccess to the open socket. For a simplified communication scheme you can implement a handler and pass it to handleResponse alongside the socket and command to run on successful authentication.
