This is used to render the list of <ô as a string of characters enclosed in double quotes, rather than between square brackets and separated by commas.Example Ðinstance Display Char where displayBuilder '\'' = "'\\''" displayBuilder c = "'" <> TB.singleton c <> "\'" -- 'displayList' is overloaded, so that when the @Display [a]@ instance calls 'displayList', -- we end up with a nice string enclosed between double quotes. displayList cs = TB.fromString $ "\"" <> showLitString cs "\"" ‘instance Display a => Display [a] where -- In this instance, 'displayBuilder' is defined in terms of 'displayList', which for most types -- is defined as the default written in the class declaration. -- But when a ~ Char, there is an explicit implementation that is selected instead, which -- provides the rendering of the character string between double quotes. displayBuilder = displayList How implementations are selected ØdisplayBuilder ([1,2,3] :: [Int]) ’C displayBuilder @[Int] = displayBuilderList @Int ’C Default `displayList` displayBuilder ("abc" :: [Char]) ’C displayBuilder @[Char] = displayBuilderList @Char ’C Custom `displayList` text-display The method   allows you to write instances that require nesting. The precedence parameter can be thought of as a suggestion coming from the surrounding context for how tightly to bind. If the precedence parameter is higher than the precedence of the operator (or constructor, function, etc.) being displayed, then that suggests that the output will need to be surrounded in parentheses in order to bind tightly enough (see  ).þFor example, if an operator constructor is being displayed, then the precedence requirement for its arguments will be the precedence of the operator. Meaning, if the argument binds looser than the surrounding operator, then it will require parentheses.ÍNote that function/constructor application has an effective precedence of 10.Examples Òinstance Display a => Display (Maybe a) where -- In this instance, we define 'displayPrec' rather than 'displayBuilder' as we need to decide -- whether or not to surround ourselves in parentheses based on the surrounding context. -- If the precedence parameter is higher than 10 (the precedence of constructor application) -- then we indeed need to surround ourselves in parentheses to avoid malformed outputs -- such as @Just Just 5@. -- We then set the precedence parameter of the inner 'displayPrec' to 11, as even -- constructor application is not strong enough to avoid parentheses. displayPrec _ Nothing = "Nothing" displayPrec prec (Just a) = displayParen (prec > 10) $ "Just " <> displayPrec 11 a èdata Pair a b = a :*: b infix 5 :*: -- arbitrary choice of precedence instance (Display a, Display b) => Display (Pair a b) where displayPrec prec (a :*: b) = displayParen (prec > 5) $ displayPrec 6 a <> " :*: " <> displayPrec 6 b text-displayConvert a value to a readable =.Examples display 3"3" display True"True"  text-display,A utility function that surrounds the given ;ó with parentheses when the Bool parameter is True.
