"""Fn-F7 toggle script for xrandr.
|
||||
|
||||
How does it work?
|
||||
|
||||
First, it's stateless, so it runs xrandr -q and parses the output into a
|
||||
RandRState object. The RandRState object defines attributes and methods to
|
||||
query and set xrandr options.
|
||||
|
||||
Second, it proceeds through the state machine toggling to the next state in
|
||||
order. The RandRStateMachine controls the transitions (i.e. it defines the
|
||||
states).
|
||||
|
||||
These steps are executed by the RandRToggleCommand that parses command line
|
||||
arguments, instantiates the RandRState and RandRStateMachine instances, and
|
||||
handles errors.
|
||||
|
||||
This is one of those programs that should have existed eons ago...
