# You can open a connection to the Lightpack that will live for the duration of the block using `.open`:
Lightpack.open do |lightpack|
  # Use `lightpack` as described below.
end

# If you want a little more control over opening and closing the connection, just use `.new`: 
lightpack = Lightpack.new("127.0.0.1", 3636, "api_key")
# "127.0.0.1" and 3636 are the default host and port and can be omitted as in the `.open` example. 
# The third parameter is the optional api key, which you need to set 
# if you've set up your Lightpack to require authentication.

# You can then explicitly open a connection to the lightpack. 
# You're responsible for closing it using `#disconnect` when you're done.
lightpack.connect

# If you need to authenticate but haven't done so yet with `.open` or `.new`, 
# you can do so manually after connecting.
lightpack.authenticate("api_key")

# The Lightpack object exposes a lot of interesting information:
lightpack.status      # :on, :off, :device_error or :unknown
lightpack.on?         # true or false
lightpack.api_status  # :idle or :busy

lightpack.profiles    # ["Lightpack", "Other profile"]
lightpack.profile     # "Lightpack"

lightpack.led_count   # 10
lightpack.led_areas   # [{:x=>1920, :y=>1224, :width=>640, :height=>216}, {:x=>2176, :y=>720, ...}, ...] 
lightpack.colors      # [[170, 170, 173], [190, 190, 192], ...] # Red, Green, Blue

lightpack.fps         # 20.04
lightpack.screen_size # [0, 0, 2560, 1440]
lightpack.mode        # :ambilight or :moodlamp

# Of course, you can also _do_ certain things with your Lightpack. 
# All of these return true when successful and raise an error otherwise.

# Note that all of the action methods above require a lock on the Lightpack.
# This lock is acquired automatically if you haven't done so manually, 
# but if you want to do a number of actions sequentially, acquiring a lock once
# would be more efficient than acquiring and releasing one for every action.

# You can acquire a lock for the duration of a block like this:
lightpack.with_lock do
  lightpack.set_color(0, 255, 0, 0)
  lightpack.set_color(1, 0, 255, 0)
  lightpack.set_color(2, 0, 0, 255)
end

# Alternatively, you can use `#lock` in combination with `#unlock`.
lightpack.lock

lightpack.brightness  = 93
lightpack.smooth      = 128
lightpack.unlock

# If you want to, you can check whether a lock is active:
lightpack.locked?

# When you're done, you can just let the program exit or disconnect explicitly.
lightpack.disconnect
