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 D vertically. All comma separators are put in front of the elements.

For example, the combinator  can be  defined with  enclosure:  0 list xs = enclosure 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] 3But when the page width is 15, it is layed out as:   list [10  ,200  ,3000] (punctuate p xs) concatenates all documents in xs with  document p except for the last document.  0 someText = 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) 3But when the page width is 15, it is layed out as:    (words,  in,  a,  tuple) B(If you want put the commas in front of their elements instead of  at the end, you should use  or, in general, .)  The document (sep xs) concatenates all documents xs either  horizontally with (<+>)*, if it fits the page, or vertically with  (<$>).  sep xs = group (vsep xs)  The document  (fillSep xs) concatenates documents xs  horizontally with (<+>)$ as long as its fits the page, than  inserts a line/ and continues doing that for all documents in  xs. ' fillSep xs = foldr (\<\/\>) empty xs  The document  (hsep xs) concatenates all documents xs  horizontally with (<+>).  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.  1 someText = map text (words ("text to lay out"))  * test = text "some" <+> vsep someText This is layed out as:    some text  to  lay  out The H5 combinator can be used to align the documents under  their first element  2 test = text "some" <+> align (vsep someText) Which is printed as:   some text  to  lay  out  The document (cat xs) concatenates all documents xs either  horizontally with (<>)*, if it fits the page, or vertically with  (<$$>).  cat xs = group (vcat xs)  The document  (fillCat xs) concatenates documents xs  horizontally with (<>), as long as its fits the page, than inserts  a  linebreak/ and continues doing that for all documents in xs. ) fillCat xs = foldr (\<\/\/\>) empty xs  The document  (hcat xs) concatenates all documents xs  horizontally with (<>).  The document  (vcat xs) concatenates all documents xs  vertically with (<$$>). If a  undoes the line breaks  inserted by vcat+, all documents are directly concatenated.  The document (x <+> y) concatenates document x and y with a  space in between. (infixr 6)  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 space in between) or underneath each  other. (infixr 5) ! The document (x <//> y) concatenates document x and y with  a $# in between. This effectively puts x and y either ? right next to each other or underneath each other. (infixr 5) e The document (x <$> y) concatenates document x and y with a  I in between. (infixr 5) " The document (x <$$> y) concatenates document x and y with  a  linebreak in between.

It is used instead of   whenever the text contains  newline characters. ? The document (int i) shows the literal integer i using   . @ The document  (integer i) shows the literal integer i using   . A The document  (float f) shows the literal float f using   . B The document  (double d) shows the literal double d using   . C The document  (rational r) shows the literal rational r using   . D 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  fillBreak, we get a useful # variation of the previous output:   ptype (name,tp) < = fillBreak 6 (text name) <+> text "::" <+> text tp The output will now be:   let empty :: Doc ) nest :: Indentation -> Doc -> Doc  linebreak  :: Doc E 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") 0 ,("nest","Indentation -> Doc -> Doc")  ,("linebreak","Doc")]   ptype (name,tp) 7 = fill 6 (text name) <+> text "::" <+> text tp  8 test = text "let" <+> align (vcat (map ptype types)) Which is layed out as:   let empty :: Doc ) nest :: Indentation -> Doc -> Doc  linebreak :: Doc F The document  (indent i x) indents document x with i spaces.  % test = indent 4 (fillSep (map text A (words "the indent combinator indents these words !"))) +Which lays out with a page width of 20 as:   the indent  combinator  indents these  words ! GAThe 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) H The document  (align x) renders document x with the nesting < level set to the current column. It is used for example to  implement G. ?As an example, we will put a document right above another one, * regardless of the current nesting level:   x $$ y = align (x <$$$> y)  7 test = text "hi" <+> (text "nice" $$ text "world") which will be layed out as:   hi nice  world IThe line7 document advances to the next line and indents to the ! current nesting level. Document line behaves like (text " ")  if the line break is undone by . JThe  linebreak3 document advances to the next line and indents to % the current nesting level. Document  linebreak behaves like  f if the line break is undone by . K The document  (nest i x) renders document x with the current , indentation level increased by i (See also G, H and  F).  9 nest 2 (text "hello" <$$$> text "world") <$$$> text "!"  outputs as:   hello  world  ! @gh !e"#$%&'()*+,-./0123456789:;<=>?@ABCDEiFGHIJKjkB  !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKB, KIJ#$HGF "!ED+%&()'*-./0123456789 :;<=?@ABC>@gh !e"#$%&'()*+,-./0123456789:;<=>?@ABCDEiFGHIJKjkl      !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSSTUVWXYZ[\]^_`abcdefghijkl_mnopqpretty-compact-1.0Text.PrettyPrint.CompactText.PrettyPrint.Compact.Corebase Data.Monoidmempty<>DocNestingColumnUnionNestCatLineTextEmptytextspacingspacegroupflattenrender Data.Functor<$>listtupled semiBraces encloseSep punctuatesepfillSephsepvsepcatfillCathcatvcat<+><$$>softline softbreaksquotesdquotesbracesparensanglesbracketsenclosecharlparenrparenlangleranglelbracerbracelbracketrbracketsquotedquotesemicoloncommadot backslashequalsstringboolintintegerfloatdoublerational fillBreakfillindenthangalignline linebreaknestNewLineProcessoverflow curIndentnumTokstokensrestDocsConsNilBoxSpacingStr Indentationlenmeasure filtering renderAlllayout $fShowDoc $fOrdProcess $fEqProcess $fMonoidDoc $fIsStringDoc<$$$>Control.ApplicativeemptyfoldDocwidthcolumnnesting
