UPDATE: Now a gem: https://github.com/henrik/activemodel-with_conditions

---

Rails with_options will overwrite if and unless conditions. So this:

with_options(if: :outer_1?, unless: :outer_2?) do
  validates :method, if: :inner_1?, unless: :inner_2?
end

Example of toggling between two inputs on a Sony Bravia TV.

E.g. a Mac Mini HTPC on HDMI 1 and a Nintendo Switch on HDMI 2.

You're assumed to have set up a pre-shared key (PSK) per https://github.com/breunigs/bravia-auth-and-remote/.

It assumes it can call send_sony_tv_command.sh. Change the path if needed.

Example usage:

henrik

module ClimateControlHelpers
  # Usage:
  #
  #    describe Foo do
  #      stub_envs(
  #        FOO: "bar",
  #      )
  #
  #      it "uses the ENVs"
  #    end
