The Int in SLine] contains the indentation for that line. The library provides two default display functions  and J. You can provide your own display function by writing a function from a  SimpleDoc to your own output format. language-luaThe abstract data type Doc represents pretty documents.Doc is an instance of the  class.  (show doc) pretty prints document docJ with a page width of 100 characters and a ribbon width of 40 characters. $show (text "hello" <$> text "world")2Which would return the string "hello\nworld", i.e.  hello world  language-lua The member  prettyList is only used to define the  instance Pretty a => Pretty [a]#. In normal circumstances only the pretty function is used. language-lua The document  (list xs) comma separates the documents xs and encloses them in square brackets. The documents are rendered horizontally if that fits the page. Otherwise they are aligned vertically. All comma separators are put in front of the elements. language-lua The document  (tupled xs) comma separates the documents xs and encloses them in parenthesis. The documents are rendered horizontally if that fits the page. Otherwise they are aligned vertically. All comma separators are put in front of the elements. language-lua The document (semiBraces xs) separates the documents xs with semi colons and encloses them in braces. The documents are rendered horizontally if that fits the page. Otherwise they are aligned vertically. All semi colons are put in front of the elements. language-lua 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  can be defined with  encloseSep: hlist 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] 2But when the page width is 15, it is layed out as: list [10 ,200 ,3000]  language-lua(punctuate p xs) concatenates all documents in xs with document p except for the last document. isomeText = map text ["words","in","a","tuple"] test = parens (align (cat (punctuate comma someText)))+This is layed out on a page width of 20 as: (words,in,a,tuple) 2But when the page width is 15, it is layed out as: (words, in, a, tuple) ^(If you want put the commas in front of their elements instead of at the end, you should use  or, in general, .) language-lua The document (sep xs) concatenates all documents xs either horizontally with (<+>)+, if it fits the page, or vertically with (<$>). sep xs = group (vsep xs) language-lua The document  (fillSep xs) concatenates documents xs horizontally with (<+>)/ as long as its fits the page, than inserts a line0 and continues doing that for all documents in xs. %fillSep xs = foldr (\<\/\>) empty xs language-lua The document  (hsep xs) concatenates all documents xs horizontally with (<+>). language-lua The document  (vsep xs) concatenates all documents xs vertically with (<$>). If a % undoes the line breaks inserted by vsep+, all documents are separated with a space. YsomeText = map text (words ("text to lay out")) test = text "some" <+> vsep someTextThis is layed out as: some text to lay out The I combinator can be used to align the documents under their first element 0test = text "some" <+> align (vsep someText)Which is printed as: $some text to lay out   language-lua The document (cat xs) concatenates all documents xs either horizontally with (<>)+, if it fits the page, or vertically with (<$$>). cat xs = group (vcat xs)! language-lua The document  (fillCat xs) concatenates documents xs horizontally with (<>)/ as long as its fits the page, than inserts a  linebreak/ and continues doing that for all documents in xs. 'fillCat xs = foldr (\<\/\/\>) empty xs" language-lua The document  (hcat xs) concatenates all documents xs horizontally with (<>).# language-lua The document  (vcat xs) concatenates all documents xs vertically with (<$$>). If a % undoes the line breaks inserted by vcat*, all documents are directly concatenated.$ language-lua The document (x <> y) concatenates document x and document y(. It is an associative operation having %' as a left and right unit. (infixr 6)& language-lua The document  (x <+> y) concatenates document x and y with a space in between. (infixr 6)' language-lua The document  (x </> y) concatenates document x and y with a (# in between. This effectively puts x and y$ either next to each other (with a space2 in between) or underneath each other. (infixr 5)) language-lua The document  (x <//> y) concatenates document x and y with a *# in between. This effectively puts x and yF either right next to each other or underneath each other.

It is used instead of G0 whenever the text contains newline characters.H language-lua The document (int i) shows the literal integer i using G.I language-lua The document  (integer i) shows the literal integer i using G.J language-lua The document  (float f) shows the literal float f using G.K language-lua The document  (double d) shows the literal double d using G.L language-lua The document  (rational r) shows the literal rational r using G.M language-lua The document (fillBreak i x) first renders document x. It than appends spaces until the width is equal to i. If the width of x is already larger than i%, the nesting level is increased by i and a line is appended. When we redefine ptype! in the previous example to use  fillBreak4, we get a useful variation of the previous output: Jptype (name,tp) = fillBreak 6 (text name) <+> text "::" <+> text tpThe output will now be: Rlet empty :: Doc nest :: Int -> Doc -> Doc linebreak :: Doc N language-lua The document  (fill i x) renders document x. It than appends spaces until the width is equal to i. If the width of x is already larger, nothing is appended. This combinator is quite useful in practice to output a list of bindings. The following example demonstrates this. types = [("empty","Doc") ,("nest","Int -> Doc -> Doc") ,("linebreak","Doc")] ptype (name,tp) = fill 6 (text name) <+> text "::" <+> text tp test = text "let" <+> align (vcat (map ptype types))Which is layed out as: Glet empty :: Doc nest :: Int -> Doc -> Doc linebreak :: Doc O language-lua The document  (indent i x) indents document x with i spaces. ctest = 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 ! P language-luaBThe hang combinator implements hanging indentation. The document  (hang i x) renders document x6 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: 2the hang combinator indents these words ! The hang combinator is implemented as: hang i x = align (nest i x) language-lua The document  (align x) renders document xY with the nesting level set to the current column. It is used for example to implement P.hAs an example, we will put a document right above another one, regardless of the current nesting level: x $$ y = align (x <$> y) 5test = text "hi" <+> (text "nice" $$ text "world")which will be layed out as: hi nice world % language-lua/The empty document is, indeed, empty. Although emptyI has no content, it does have a 'height' of 1 and behaves exactly like  (text "")! (and is therefore not a unit of <$>).Q language-lua The document (char c) contains the literal character c). The character shouldn't be a newline ('\n'), the function ,! should be used for line breaks.G language-lua The document (text s) contains the literal string s-. The string shouldn't contain any newline ('\n'G) characters. If the string contains newline characters, the function F should be used., language-luaThe lineX document advances to the next line and indents to the current nesting level. Document line behaves like  (text " ")! if the line break is undone by .R language-luaThe  linebreakX document advances to the next line and indents to the current nesting level. Document  linebreak behaves like % if the line break is undone by .S language-lua The document  (nest i x) renders document x> with the current indentation level increased by i (See also P,  and O). 3nest 2 (text "hello" <$> text "world") <$> text "!" outputs as: hello world !  language-luaThe groupB combinator is used to specify alternative layouts. The document  (group x)% undoes all line breaks in document xb. The resulting line is added to the current line if that fits the page. Otherwise, the document x" is rendered without any changes. language-lua4This is the default pretty printer which is used by T, U and V. !(renderPretty ribbonfrac width x) renders document x with a page width of width and a ribbon width of (ribbonfrac * width)m characters. The ribbon width is the maximal amount of non-indentation characters on a line. The parameter  ribbonfrac should be between 0.0 and 1.0;. If it is lower or higher, the ribbon width will be 0 or width respectively.W language-lua(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. language-lua(displayS simpleDoc) takes the output  simpleDoc3 from a rendering function and transforms it to a X type (for use in the  class). VshowWidth :: Int -> Doc -> String showWidth w x = displayS (renderPretty 0.4 w x) "" language-lua(displayIO handle simpleDoc) writes  simpleDoc to the file handle handle'. This function is used for example by V: AhPutDoc handle doc = displayIO handle (renderPretty 0.4 100 doc)U language-lua The action  (putDoc doc) pretty prints document docc to the standard output, with a page width of 100 characters and a ribbon width of 40 characters. Amain :: IO () main = do{ putDoc (text "hello" <+> text "world") }Which would output  hello world V language-lua(hPutDoc handle doc) pretty prints document doc to the file handle handleJ with a page width of 100 characters and a ribbon width of 40 characters. main = do{ handle <- openFile "MyFile" WriteMode ; hPutDoc handle (vcat (map text ["vertical","text"])) ; hClose handle }SYZ[\]^
