--- ### Description
--- AwesomeWM lifecycle API.
---
--- This module contains the functions and signal to manage the lifecycle of the AwesomeWM process.
--- It allows to execute code at specific point from the early initialization all the way to the last events before exiting or restarting.
---
--- Additionally it handles signals for spawn and keyboard related events.

--- ### Description
--- Connect to a signal.
--- ### Parameters
--- @param name AwesomeAPISignal The name of the signal.
--- @param action function The callback to call when the signal is emitted.

function awesome:connect_signal(name, action) end

--- ### Description
--- Connect to a signal weakly.
---
--- This allows the callback function to be garbage collected and automatically disconnects the signal when that happens.
--- ### Parameters
--- @param name AwesomeAPISignal The name of the signal.
--- @param action function The callback to call when the signal is emitted.
--- ### Warnings
--- > Only use this function if you really, really, really know what you are doing.

--- ### Description
--- Emit a signal.
--- ### Parameters
--- @param name AwesomeAPISignal The name of the signal.
