Pretty-printing library This package contains a pretty-printing library, a set of API's that provides a way to easily print out text in a consistent format of your choosing. This is useful for compilers and related tools. This library was originally designed by John Hughes's and has since been heavily modified by Simon Peyton Jones.

>>> pretty 1 <+> pretty "hello" <+> pretty 1.234

Prettify generated JSON documentation.

docs (pretty (Proxy :: Proxy MyAPI))

pretty shows a value using its Buildable instance.

Converts TOML type into Text (using defaultOptions). For example, this

TOML
{ tomlPairs  = HashMap.fromList
[("title", AnyValue $ Text "TOML example")]
, tomlTables = PrefixTree.fromList
[( "example" <| "owner"
, mempty
{ tomlPairs  = HashMap.fromList
[("name", AnyValue $ Text Kowainik)]
}
)]
, tomlTableArrays = mempty
}

will be translated to this

title = "TOML Example"

[example.owner]
name = "Kowainik"

The default pretty printer returning Strings Equivalent to

prettyStyle defaultStyle

Where defaultStyle = (mode=PageMode, lineLength=80, ribbonsPerLine=1.5)

pretty print the given value

Configuration to print to a pretty human readable CSS output.
