Example of a configuration file:

  [gui]
  font = Misc Fixed Semicondensed 10

  [text]
  # default is `indentation = tabs'
  indentation = 4 spaces

  [editor]
  line-numbers = false
  show-invisibles = tabs, spaces

  # the following are simply the defaults for insert mode
  # editor.colors.insert is also available
  [editor.colors.select]
  background = hsv(184, 18, 100)
  foreground = hsv(184, 18, 29)
  invisibles = hsv(184, 18, 60)
  selection = hsv(184, 9, 100)
  line-numbers.background = hsv(184, 18, 90)
  # the following would be equivalent to the above line:
  #
  #   [editor.colors.insert.line-numbers]
  #   background = hsv(184, 18, 90)
  #
