The Int in SLine] contains the indentation for that line. The library provides two default display functions f and eJ. You can provide your own display function by writing a function from a  SimpleDoc to your own output format. wl-pprint-annotatedThe 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 wl-pprint-annotated The member  prettyList is only used to define the  instance Pretty a => Pretty [a]#. In normal circumstances only the pretty function is used.wl-pprint-annotated The document  (list xs) comma separates the documents xsÆ 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.wl-pprint-annotated 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.wl-pprint-annotated The document (semiBraces xs) separates the documents xsÉ 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.wl-pprint-annotated 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 ] wl-pprint-annotated(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, .)!wl-pprint-annotated The document (sep xs) concatenates all documents xs either horizontally with (<+>)+, if it fits the page, or vertically with (<#>). sep xs = group (vsep xs)"wl-pprint-annotated The document  (fillSep xs) concatenates documents xs horizontally with (<+>)/ as long as its fits the page, then inserts a line0 and continues doing that for all documents in xs. #fillSep xs = foldr (</>) mempty xs#wl-pprint-annotated The document  (hsep xs) concatenates all documents xs horizontally with (<+>).$wl-pprint-annotated The document  (vsep xs) concatenates all documents xs vertically with (<#>).

It then 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: [let mempty :: Doc a nest :: Int -> Doc a -> Doc a linebreak :: Doc a Iwl-pprint-annotated The document  (fill i x) renders document x. It then appends spaces until the width is equal to i. If the width of xž is already larger, nothing is appended. This combinator is quite useful in practice to output a list of bindings. The following example demonstrates this. įtypes = [("mempty","Doc a") ,("nest","Int -> Doc a -> Doc a") ,("linebreak","Doc a")] ptype (name,tp) = fill 6 (text name) <+> text "::" <+> text tp test = text "let" <+> align (vcat (map ptype types))Which is layed out as: Plet mempty :: Doc a nest :: Int -> Doc a -> Doc a linebreak :: Doc a Kwl-pprint-annotated 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 ! Lwl-pprint-annotatedBThe 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)Mwl-pprint-annotated The document  (align x) renders document xY with the nesting level set to the current column. It is used for example to implement L.hAs an example, we will put a document right above another one, regardless of the current nesting level: x $$ y = align (x <#> y) 2test = text "hi" <+> (text "nice" $$ text "world")which will be layed out as: hi nice world Nwl-pprint-annotatedAnnotate a document.Owl-pprint-annotated'Remove the annotations from a document.Pwl-pprint-annotated The document (char c) contains the literal character c). The character shouldn't be a newline ('\n'), the function R! should be used for line breaks.Qwl-pprint-annotated 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  should be used.Rwl-pprint-annotatedThe 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 Z.Swl-pprint-annotatedThe  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 Z.Twl-pprint-annotatedUA linebreak that can not be flattened; it is guaranteed to be rendered as a newline.Uwl-pprint-annotated The document  (nest i x) renders document x> with the current indentation level increased by i (See also L, M and K). 3nest 2 (text "hello" <#> text "world") <#> text "!" outputs as: hello world ! Zwl-pprint-annotatedThe 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.[wl-pprint-annotatedflatAlt creates a document that changes when flattened; normally it is rendered as the first argument, but when flattened is rendered as the second.]wl-pprint-annotated4This is the default pretty printer which is used by œ, j and k. !(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.^wl-pprint-annotated4This is the default pretty printer which is used by œ, j and kX. This routine uses a page width of 100 characters and a ribbon width of 40 characters._wl-pprint-annotatedģA 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: Æfun( | fun( | fun( | fun( | fun([ | abcdef, abcdef, ] | ))))) | /Which fits within the 20c. mark. In addition,  renderSmartŪ 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]) `wl-pprint-annotated(renderCompact x) renders document xð 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.cwl-pprint-annotatedDisplay a rendered document.„This function takes a means of pushing an annotated region, a means of ending it, and a means of displaying a string, with effects f" to display or compute the output o.dwl-pprint-annotatedDisplay a rendered document.ŒThis function takes a means of pushing an annotated region, a means of ending it, and a means of displaying a string to compute the output o.ewl-pprint-annotated(displayIO handle simpleDoc) writes  simpleDoc to the file handle handleD, discarding all annotations.
