--
-- "A prettier printer"
-- Draft paper, April 1997, revised March 1998.
-- http://homepages.inf.ed.ac.uk/wadler/papers/prettier/prettier.pdf
--
--
-- This is an implementation of the pretty printing combinators described
-- by Philip Wadler (1997). In their bare essence, the combinators of
-- Wadler are not expressive enough to describe some commonly occurring
-- layouts. The PPrint library adds new primitives to describe these
-- layouts and works well in practice.
--
-- The library is based on a single way to concatenate documents, which
-- is associative and has both a left and right unit. This simple design
-- leads to an efficient and short implementation. The simplicity is
-- reflected in the predictable behaviour of the combinators which make
-- them easy to use in practice.
--
-- A thorough description of the primitive combinators and their
-- implementation can be found in Philip Wadler's paper (1997). Additions
-- and the main differences with his original paper are:
--
--
-- - The nil document is called mempty. We cannot use
-- empty for compatibility with base.
-- - The operator </> is used for soft line breaks.
-- - There are three new primitives: align, fill and
-- fillBreak. These are very useful in practice.
-- - Lots of other useful combinators, like fillSep and
-- list.
-- - There are three renderers, 'renderPretty/renderPrettyDefault' and
-- renderSmart for pretty printing and renderCompact for
-- compact output. The pretty printing algorithm also uses a ribbon-width
-- now for even prettier output.
-- - There are display routines displayS and display for
-- strings, displayT for lazy text, displayIO for file
-- based output. Generalized display routines for display with
-- annotations are provided, i.e., displayDecoratedA and
-- displayDecorated. Furthermore displaySpans exists which
-- creates a monoid and a SpanList of the annotations.
-- - There is a Pretty class which creates documents without
-- annotations.
-- - The implementation uses optimised representations and strictness
-- annotations.
-- - There is the wl-pprint-console package, based on this package,
-- which provides additional display routines, e.g., colorful output
-- using ANSI escape sequences.

module Text.PrettyPrint.Annotated.WL
-- | The data type Doc represents pretty documents.
--
-- Doc is an instance of the Show class. (show

-- show (text "hello" <#> text "world")
--
--
-- Which would return the string "hello\nworld", i.e.
--
--
-- hello

-- | The document (text s) contains the literal string s.
-- The string shouldn't contain any newline ('\n') characters.
-- If the string contains newline characters, the function pretty
-- should be used.
text :: String -> Doc a
-- | The document (nest i x) renders document x with the
-- current indentation level increased by i (See also hang,
-- align and indent).
--
--
-- nest 2 (text "hello" <#> text "world") <#> text "!"

nest :: Int -> Doc a -> Doc a
-- | The line document advances to the next line and indents to

line :: Doc a
-- | The linebreak document advances to the next line and indents
-- to the current nesting level. Document linebreak behaves like
-- mempty if the line break is undone by group.
linebreak :: Doc a
-- | The group combinator is used to specify alternative layouts.
-- The document (group x) undoes all line breaks in document
-- x. The resulting line is added to the current line if that

-- | The document (align x) renders document x with the

--
-- As an example, we will put a document right above another one,
-- regardless of the current nesting level:
--
--
-- x $$ y = align (x <#> y)
--
--
--
-- test = text "hi" <+> (text "nice" $$ text "world")
--
--
-- which will be layed out as:

--
align :: Doc a -> Doc a
-- | The hang combinator implements hanging indentation. The document
-- (hang i x) renders document x with a nesting level
-- set to the current column plus i. The following example uses
-- hanging indentation for some text:
--
--
-- test = hang 4 (fillSep (map text
-- (words "the hang combinator indents these words !")))
--
--
-- Which lays out on a page with a width of 20 characters as:
--
--
-- the hang combinator
-- indents these
-- words !
--
--
-- The hang combinator is implemented as:
--
--
-- hang i x = align (nest i x)
--
hang :: Int -> Doc a -> Doc a
-- | The document (indent i x) indents document x with
-- i spaces.
--
--
-- test = indent 4 (fillSep (map text
-- (words "the indent combinator indents these words !")))
--
--
-- Which lays out with a page width of 20 as:
--
--
-- the indent
-- combinator
-- indents these
-- words !
--
indent :: Int -> Doc a -> Doc a
-- | The document (encloseSep l r sep xs) concatenates the
-- documents xs separated by sep and encloses the
-- resulting document by l and r. The documents are
-- rendered horizontally if that fits the page. Otherwise they are
-- aligned vertically. All separators are put in front of the elements.
-- For example, the combinator list can be defined with
-- encloseSep:
--
--
-- list xs = encloseSep lbracket rbracket comma xs
-- test = text "list" <+> (list (map int [10,200,3000]))
--
--
-- Which is layed out with a page width of 20 as:

--
-- list [10, 200, 3000]

--
--
-- The align combinator can be used to align the documents under

vsep :: Foldable f => f (Doc a) -> Doc a

punctuate :: Traversable f => Doc a -> f (Doc a) -> f (Doc a)
-- | The document (fill i x) renders document x. It then

fill :: Int -> Doc a -> Doc a
-- | The document (fillBreak i x) first renders document

-- of the previous output:
--
--
-- ptype (name,tp)
-- = fillBreak 6 (text name) <+> text "::" <+> text tp

renderPrettyDefault :: Doc a -> SimpleDoc a
-- | This is the default pretty printer which is used by show,

-- x) renders document x with a page width of
-- width and a ribbon width of (ribbonfrac * width)
-- characters. The ribbon width is the maximal amount of non-indentation
-- characters on a line. The parameter ribbonfrac should be

-- ribbon width will be 0 or width respectively.
renderPretty :: Float -> Int -> Doc a -> SimpleDoc a
-- | (renderCompact x) renders document x without adding
-- any indentation. Since no 'pretty' printing is involved, this renderer
-- is very fast. The resulting output contains fewer characters than a
-- pretty printed version and can be used for output that is read by
-- other programs.
renderCompact :: Doc a -> SimpleDoc a
-- | A slightly smarter rendering algorithm with more lookahead. It
-- provides provide earlier breaking on deeply nested structures. For
-- example, consider this python-ish pseudocode:
-- fun(fun(fun(fun(fun([abcdefg, abcdefg]))))) If we put a
-- softbreak (+ nesting 2) after each open parenthesis, and align the
-- elements of the list to match the opening brackets, this will render
-- with renderPretty and a page width of 20c as:
-- fun(fun(fun(fun(fun([ | abcdef, | abcdef, ] ))))) | Where the
-- 20c. boundary has been marked with |. Because renderPretty
-- only uses one-line lookahead, it sees that the first line fits, and is
-- stuck putting the second and third lines after the 20c mark. In
-- contrast, renderSmart will continue to check the potential
-- document up to the end of the indentation level. Thus, it will format
-- the document as:
--
--
-- fun( |
-- fun( |
-- fun( |
-- fun( |
-- fun([ |
-- abcdef,
-- abcdef,
-- ] |
-- ))))) |
--
--
-- Which fits within the 20c. mark. In addition, renderSmart
-- uses this lookahead to minimize the number of lines printed, leading
-- to more compact and visually appealing output. Consider this example
-- using the same syntax as above: aaaaaaaaaaa([abc, def, ghi])
-- When rendered with renderPretty and a page width of 20c, we
-- get: aaaaaaaaaaa([ abc , def , ghi ]) Whereas when rendered
-- with renderSmart and a page width of 20c, we get:
-- aaaaaaaaaaa( [abc, def, ghi])
