Basic types and functions
The abstract data type Doc annann.
More specifically, a value of type Doc
The annotation is an arbitrary piece of data associated with (part of) a document. Annotations may be used by the rendering backends in order to display output differently, such as
- color information (e.g. when rendering to the terminal)
- mouseover text (e.g. when rendering to rich HTML)
- whether to show something or not (to allow simple or detailed versions)
The simplest way to display a Doc is via the Show class.
>>>putStrLn (show (vsep ["hello", "world"]))hello world

Methods
>>>pretty 1 <+> pretty "hello" <+> pretty 1.2341 hello 1.234
prettyList ∷ [a] → Doc ann Source #
prettyListinstance
. In normal circumstances only the Pretty a => Pretty [a]pretty
>>>prettyList [1, 23, 456][1, 23, 456]
Instances
class PrettyBy config a where Source #
A class for pretty-printing values in a configurable manner.
A basic example:
>>>data Case = UpperCase | LowerCase>>>data D = D>>>instance PrettyBy Case D where prettyBy UpperCase D = "D"; prettyBy LowerCase D = "d">>>prettyBy UpperCase DD>>>prettyBy LowerCase Dd
The library provides instances for common types like Integer or Bool, so you can't define
your own PrettyBy SomeConfig Integer instance. And for the same reason you should not define
instances like PrettyBy SomeAnotherConfig a for universally quantified a, because such an
instance would overlap with the existing ones. Take for example
>>>data ViaShow = ViaShow>>>instance Show a => PrettyBy ViaShow a where prettyBy ViaShow = pretty . show
with such an instance prettyBy ViaShow (1 :: Int) throws an error about overlapping instances:
• Overlapping instances for PrettyBy ViaShow Int
arising from a use of ‘prettyBy’
Matching instances:
instance PrettyDefaultBy config Int => PrettyBy config Int
instance [safe] Show a => PrettyBy ViaShow aThere's a newtype provided specifically for the purpose of defining a PrettyBy instance for
any a: PrettyAny. Read its docs for details on when you might want to use it.
The PrettyBy instance for common types is defined in a way that allows to override default
pretty-printing behaviour, read the docs of HasPrettyDefaults for details.

Nothing
Methods
prettyBy ∷ config → a → Doc ann Source #
Pretty-print a value of type a the way a config specifies it.
The default implementation of prettyBy is in terms of pretty, defaultPrettyFunctorBy
or defaultPrettyBifunctorBy depending on the kind of the data type that you're providing
an instance for. For example, the default implementation of prettyBy for a monomorphic type
is going to be "ignore the config and call pretty over the value":
>>>newtype N = N Int deriving newtype (Pretty)>>>instance PrettyBy () N>>>prettyBy () (N 42)42
The default implementation of prettyBy for a Functor is going to be in terms of
defaultPrettyFunctorBy:
>>>newtype N a = N a deriving stock (Functor) deriving newtype (Pretty)>>>instance PrettyBy () a => PrettyBy () (N a)>>>prettyBy () (N (42 :: Int))42
It's fine for the data type to have a phantom parameter as long as the data type is still a
Functor (i.e. the parameter has to be of kind Type). Then defaultPrettyFunctorBy is used
again:
>>>newtype N a = N Int deriving stock (Functor) deriving newtype (Pretty)>>>instance PrettyBy () (N b)>>>prettyBy () (N 42)42
If the data type has a single parameter of any other kind, then it's not a functor and so
like in the monomorphic case pretty is used:
>>>newtype N (b :: Bool) = N Int deriving newtype (Pretty)>>>instance PrettyBy () (N b)>>>prettyBy () (N 42)42
Same applies to a data type with two parameters: if both the parameters are of kind Type,
then the data type is assumed to be a Bifunctor and hence defaultPrettyBifunctorBy is
used. If the right parameter is of kind Type and the left parameter is of any other kind,
then we fallback to assuming the data type is a Functor and defining prettyBy as
defaultPrettyFunctorBy. If both the parameters are not of kind Type, we fallback to
implementing prettyBy in terms of pretty like in the monomorphic case.
Note that in all those cases a Pretty instance for the data type has to already exist,
so that we can derive a PrettyBy one in terms of it. If it doesn't exist or if your data
type is not supported (for example, if it has three or more parameters of kind Type), then
you'll need to provide the implementation manually.
prettyListBy ∷ config → [a] → Doc ann Source #
prettyListBy is used to define the default PrettyBy instance for [a] and NonEmpty a.
In normal circumstances only the prettyBy function is used.
The default implementation of prettyListBy is in terms of defaultPrettyFunctorBy.
