A simple automation daemon designed to interact with Elgato Stream Deck devices. See example.toml for a set of example automations, and the docs for further information on automation options.
WIP, basic functionality working, tested only with a stream deck mini, pull requests welcome.
An automation file consists of a list of [[automata]], each corresponding to a single button on a stream deck.
These automata have a state field describing their intitial state, as well as an on_init executor.
Each automata contains a set of named states (for example, [automata.states.error]), these may contain on_press and on_poll executors, called when the button is pressed or under periodic polling, as well as a display object that defines what will be displayed on the button in a given state.
Executors contain instructions about commands that should be executed and how these effect the state of an automata. These contain a func argument that is the command to be executed, an args list of arguments to be passed to the command (note that args cannot be included in the func string directly), a pair of on_success and on_failure fields mapping to the next states.
In general success is determined by the return code of the command (0 = success, non-0 = error), however, in some instances a command will always return 0 however may not have executed the desired action. In these cases you may use the success_filter and failure_filter fields that to check for matching data from standard out, and the on_failure next state field mapping.
