defmodule Dala.Theme.Adaptive do

  @moduledoc """

  Theme that follows the OS-level light / dark setting.



  At call time `theme/0` reads `Dala.Theme.color_scheme/0` and returns

  `Dala.Theme.Light.theme/0` or `Dala.Theme.Dark.theme/0`. Built for

  outdoor working users — sun-readable in daytime, eye-friendly at night.



  ## Usage



      defmodule MyApp do

        use Dala.App, theme: Dala.Theme.Adaptive

      end



  ## Reactive switching



  `Dala.Theme.set/1` snapshots the theme at call time, so toggling the OS

  appearance after the app has started does not auto-update the rendered

  theme. To re-evaluate, call `Dala.Theme.set(Dala.Theme.Adaptive)` again

  (e.g. in response to a foreground / lifecycle event, or after a planned

  `:color_scheme_changed` device event in a future version).

  """



  @doc "Returns the Light or Dark theme struct based on the current OS appearance."

  @spec theme() :: Dala.Theme.t()

  def theme do

    case Dala.Theme.color_scheme() do

      :dark -> Dala.Theme.Dark.theme()

      _ -> Dala.Theme.Light.theme()

    end

  end
