Basic types and functions
The abstract data type
represents pretty documents that have
been annotated with data of type Doc
annann
.
More specifically, a value of type
represents a non-empty set of
possible layouts of a document. The layout functions select one of these
possibilities, taking into account things like the width of the output
document.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
Instances
>>>
pretty 1 <+> pretty "hello" <+> pretty 1.234
1 hello 1.234
prettyList ∷ [a] → Doc ann Source #
is only used to define the prettyList
instance
. In normal circumstances only the Pretty
a => Pretty
[a]
function is used.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 D
D>>>
prettyBy LowerCase D
d
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 a
There'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
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

.
