Switch card background or invert theme

Say you have different card types with different colors or themes but you would like to change the theme quickly without changing all parameters for each method inside Squib::Deck.new().

You could use something like the following snippet to have one place to define the color/theme and use that in all map functions. The example inverts the color from white to black for one card type. Use a switch-statement inside the map function to differentiate multiple types.

It's possible to use that for e.g. background color, text color or to choose the correct SVG for that color scheme (e.g. use the white or the black version of an image).

  # define the color, e.g. choose between white and black to quickly change the color scheme for the cards.
  color = 'black'

  background_color = all_cards['Type'].map { |t|
      if color == 'black' && t == "Type1" then
          "black"
      else
          "white"
      end
  }
  background color: background_color

  text_color = all_cards['Type'].map { |t|
      if color == 'black' && t == "Type1" then
          "white"
      else
          "black"
      end
  }

  text str: all_cards['Type'], layout: 'title', color: text_color

  svg file: all_cards['Type'].map { |t|
      if color == 'black' && t == "Type1" then
          "icons/#{t.downcase}-white.svg"
      else
          "icons/#{t.downcase}.svg"
      end
  }, layout: 'illustration'
