-- | 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.
@package pretty
@version 1.1.3.6


-- | This module provides a version of pretty that allows for annotations
--   to be attached to documents. Annotations are arbitrary pieces of
--   metadata that can be attached to sub-documents.
module Text.PrettyPrint.Annotated.HughesPJ

-- | The abstract type of documents. A Doc represents a <i>set</i> of
--   layouts. A Doc with no occurrences of Union or NoDoc represents just
--   one layout.
data Doc a

-- | A TextDetails represents a fragment of text that will be output at
--   some point in a <tt>Doc</tt>.
data TextDetails

-- | A single Char fragment
Chr :: {-# UNPACK #-} !Char -> TextDetails

-- | A whole String fragment
Str :: String -> TextDetails

-- | Used to represent a Fast String fragment but now deprecated and
--   identical to the Str constructor.
PStr :: String -> TextDetails

-- | An annotation (side-metadata) attached at a particular point in a
--   <tt>Doc</tt>. Allows carrying non-pretty-printed data around in a
--   <tt>Doc</tt> that is attached at particular points in the structure.
--   Once the <tt>Doc</tt> is render to an output type (such as
--   <a>String</a>), we can also retrieve where in the rendered document
--   our annotations start and end (see <a>Span</a> and
--   <a>renderSpans</a>).
data AnnotDetails a

module Text.PrettyPrint.HughesPJ

-- | The abstract type of documents. A Doc represents a <i>set</i> of

-- | A single Char fragment

char :: Char -> Doc

-- | A document of height 1 containing a literal string. <a>text</a>
