layoutCompact :: Doc ann1 -> SimpleDocStream ann2 #

(layoutCompact x) lays out the document x without adding any indentation and without preserving annotations. Since no 'pretty' printing is involved, this layouter is very fast. The resulting output contains fewer characters than a prettyprinted version and can be used for output that is read by other programs.

>>> let doc = hang 4 (vsep ["lorem", "ipsum", hang 4 (vsep ["dolor", "sit"])])
>>> doc
lorem
    ipsum
    dolor
        sit
>>> let putDocCompact = renderIO System.IO.stdout . layoutCompact
>>> putDocCompact doc
lorem
ipsum
dolor
sit

layoutSmart :: LayoutOptions -> Doc ann -> SimpleDocStream ann #

A layout algorithm with more lookahead than layoutPretty, that introduces line breaks earlier if the content does not (or will not, rather) fit into one line.

Consider the following python-ish document,

>>> let fun x = hang 2 ("fun(" <> softline' <> x) <> ")"
>>> let doc = (fun . fun . fun . fun . fun) (align (list ["abcdef", "ghijklm"]))

which we’ll be rendering using the following pipeline (where the layout algorithm has been left open):

>>> import Data.Text.IO as T
>>> import Prettyprinter.Render.Text
>>> let hr = pipe <> pretty (replicate (26-2) '-') <> pipe
>>> let go layouter x = (T.putStrLn . renderStrict . layouter (LayoutOptions (AvailablePerLine 26 1))) (vsep [hr, x, hr])

If we render this using layoutPretty with a page width of 26 characters per line, all the fun calls fit into the first line so they will be put there:

>>> go layoutPretty doc
|------------------------|
fun(fun(fun(fun(fun(
                  [ abcdef
                  , ghijklm ])))))
|------------------------|

Note that this exceeds the desired 26 character page width. The same document, rendered with layoutSmart, fits the layout contstraints:

>>> go layoutSmart doc
|------------------------|
fun(
  fun(
    fun(
      fun(
        fun(
          [ abcdef
          , ghijklm ])))))
|------------------------|

The key difference between layoutPretty and layoutSmart is that the latter will check the potential document until it encounters a line with the same indentation or less than the start of the document. Any line encountered earlier is assumed to belong to the same syntactic structure. layoutPretty checks only the first line.

Consider for example the question of whether the As fit into the document below:

1 A
2   A
3  A
4 B
5   B

layoutPretty will check only line 1, ignoring whether e.g. line 2 might already be too wide. By contrast, layoutSmart stops only once it reaches line 4, where the B has the same indentation as the first A.

layoutPretty :: LayoutOptions -> Doc ann -> SimpleDocStream ann #

This is the default layout algorithm, and it is used by show, putDoc and hPutDoc.

layoutPretty commits to rendering something in a certain way if the next element fits the layout constraints; in other words, it has one SimpleDocStream element lookahead when rendering. Consider using the smarter, but a bit less performant, layoutSmart algorithm if the results seem to run off to the right before having lots of line breaks.

defaultLayoutOptions :: LayoutOptions #

The default layout options, suitable when you just want some output, and don’t particularly care about the details. Used by the Show instance, for example.

>>> defaultLayoutOptions
LayoutOptions {layoutPageWidth = AvailablePerLine 80 1.0}

removeTrailingWhitespace :: SimpleDocStream ann -> SimpleDocStream ann #

Remove all trailing space characters.

This has some performance impact, because it does an entire additional pass over the SimpleDocStream.

No trimming will be done inside annotations, which are considered to contain no (trimmable) whitespace, since the annotation might actually be about the whitespace, for example a renderer that colors the background of trailing whitespace, as e.g. git diff can be configured to do.

Historical note: Since v1.7.0, layoutPretty and layoutSmart avoid producing the trailing whitespace that was the original motivation for creating removeTrailingWhitespace. See https://github.com/quchen/prettyprinter/pull/139 for some background info.

fuse :: FusionDepth -> Doc ann -> Doc ann #

(fuse depth doc) combines text nodes so they can be rendered more efficiently. A fused document is always laid out identical to its unfused version.

When laying a Document out to a SimpleDocStream, every component of the input is translated directly to the simpler output format. This sometimes yields undesirable chunking when many pieces have been concatenated together.

For example

>>> "a" <> "b" <> pretty 'c' <> "d"
abcd

results in a chain of four entries in a SimpleDocStream, although this is fully equivalent to the tightly packed

>>> "abcd" :: Doc ann
abcd

which is only a single SimpleDocStream entry, and can be processed faster.

It is therefore a good idea to run fuse on concatenations of lots of small strings that are used many times:

>>> let oftenUsed = fuse Shallow ("a" <> "b" <> pretty 'c' <> "d")
>>> hsep (replicate 5 oftenUsed)
abcd abcd abcd abcd abcd

alterAnnotationsS :: (ann -> Maybe ann') -> SimpleDocStream ann -> SimpleDocStream ann' #

Change the annotation of a document to a different annotation, or none at all. alterAnnotations for SimpleDocStream.

Note that the Doc version is more flexible, since it allows changing a single annotation to multiple ones. (SimpleDocTree restores this flexibility again.)

reAnnotateS :: (ann -> ann') -> SimpleDocStream ann -> SimpleDocStream ann' #

Change the annotation of a document. reAnnotate for SimpleDocStream.

unAnnotateS :: SimpleDocStream ann -> SimpleDocStream xxx #

Remove all annotations. unAnnotate for SimpleDocStream.

alterAnnotations :: (ann -> [ann']) -> Doc ann -> Doc ann' #

Change the annotations of a Document. Individual annotations can be removed, changed, or replaced by multiple ones.

This is a general function that combines unAnnotate and reAnnotate, and it is useful for mapping semantic annotations (such as »this is a keyword«) to display annotations (such as »this is red and underlined«), because some backends may not care about certain annotations, while others may.

Annotations earlier in the new list will be applied earlier, i.e. returning [Bold, Green] will result in a bold document that contains green text, and not vice-versa.

Since this traverses the entire Doc tree, including parts that are not rendered due to other layouts fitting better, it is preferrable to reannotate after producing the layout by using alterAnnotationsS.

reAnnotate :: (ann -> ann') -> Doc ann -> Doc ann' #

Change the annotation of a Document.

Useful in particular to embed documents with one form of annotation in a more generally annotated document.

Since this traverses the entire Doc tree, including parts that are not rendered due to other layouts fitting better, it is preferrable to reannotate after producing the layout by using reAnnotateS.

Since reAnnotate has the right type and satisfies 'reAnnotate id = id', it is used to define the Functor instance of Doc.

unAnnotate :: Doc ann -> Doc xxx #

Remove all annotations.

Although unAnnotate is idempotent with respect to rendering,

unAnnotate . unAnnotate = unAnnotate

it should not be used without caution, for each invocation traverses the entire contained document. If possible, it is preferrable to unannotate after producing the layout by using unAnnotateS.

annotate :: ann -> Doc ann -> Doc ann #

Add an annotation to a Doc. This annotation can then be used by the renderer to e.g. add color to certain parts of the output. For a full tutorial example on how to use it, see the Prettyprinter.Render.Tutorials.StackMachineTutorial or Prettyprinter.Render.Tutorials.TreeRenderingTutorial modules.

This function is only relevant for custom formats with their own annotations, and not relevant for basic prettyprinting. The predefined renderers, e.g. Prettyprinter.Render.Text, should be enough for the most common needs.

surround :: Doc ann -> Doc ann -> Doc ann -> Doc ann #

(surround x l r) surrounds document x with l and r.

>>> surround "·" "A" "Z"
A·Z

This is merely an argument reordering of enclose, but allows for definitions like

>>> concatWith (surround dot) ["Prettyprinter", "Render", "Text"]
Prettyprinter.Render.Text

enclose #

Arguments

:: Doc ann

L

-> Doc ann

R

-> Doc ann

x

-> Doc ann

LxR

(enclose l r x) encloses document x between documents l and r using <>.

>>> enclose "A" "Z" "·"
A·Z
enclose l r x = l <> x <> r

plural #

Arguments

:: (Num amount, Eq amount) 
=> doc

1 case

-> doc

other cases

-> amount 
-> doc 

(plural n one many) is one if n is 1, and many otherwise. A typical use case is adding a plural "s".

>>> let things = [True]
>>> let amount = length things
>>> pretty things <+> "has" <+> pretty amount <+> plural "entry" "entries" amount
[True] has 1 entry

fillBreak #

Arguments

:: Int

Append spaces until the document is at least this wide

-> Doc ann 
-> Doc ann 

(fillBreak i x) first lays out the document x. 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 example given in fill to use fillBreak, we get a useful variation of the output:

>>> let types = [("empty","Doc"), ("nest","Int -> Doc -> Doc"), ("fillSep","[Doc] -> Doc")]
>>> let ptype (name, tp) = fillBreak 5 (pretty name) <+> "::" <+> pretty tp
>>> "let" <+> align (vcat (map ptype types))
let empty :: Doc
    nest  :: Int -> Doc -> Doc
    fillSep
          :: [Doc] -> Doc

fill #

Arguments

:: Int

Append spaces until the document is at least this wide

-> Doc ann 
-> Doc ann 

(fill i x) lays out the document x. It then appends spaces until the width is equal to i. If the width of x is already larger, nothing is appended.

This function is quite useful in practice to output a list of bindings:

>>> let types = [("empty","Doc"), ("nest","Int -> Doc -> Doc"), ("fillSep","[Doc] -> Doc")]
>>> let ptype (name, tp) = fill 5 (pretty name) <+> "::" <+> pretty tp
>>> "let" <+> align (vcat (map ptype types))
let empty :: Doc
    nest  :: Int -> Doc -> Doc
    fillSep :: [Doc] -> Doc

pageWidth :: (PageWidth -> Doc ann) -> Doc ann #

Layout a document depending on the page width, if one has been specified.

>>> let prettyPageWidth (AvailablePerLine l r) = "Width:" <+> pretty l <> ", ribbon fraction:" <+> pretty r
>>> let doc = "prefix" <+> pageWidth (brackets . prettyPageWidth)
>>> putDocW 32 (vsep [indent n doc | n <- [0,4,8]])
prefix [Width: 32, ribbon fraction: 1.0]
    prefix [Width: 32, ribbon fraction: 1.0]
        prefix [Width: 32, ribbon fraction: 1.0]

width :: Doc ann -> (Int -> Doc ann) -> Doc ann #

(width doc f) lays out the document doc, and makes the column width of it available to a function.

>>> let annotate doc = width (brackets doc) (\w -> " <- width:" <+> pretty w)
>>> align (vsep (map annotate ["---", "------", indent 3 "---", vsep ["---", indent 4 "---"]]))
[---] <- width: 5
[------] <- width: 8
[   ---] <- width: 8
[---
    ---] <- width: 8

nesting :: (Int -> Doc ann) -> Doc ann #

Layout a document depending on the current nesting level. align is implemented in terms of nesting.

>>> let doc = "prefix" <+> nesting (\l -> brackets ("Nested:" <+> pretty l))
>>> vsep [indent n doc | n <- [0,4,8]]
prefix [Nested: 0]
    prefix [Nested: 4]
        prefix [Nested: 8]

column :: (Int -> Doc ann) -> Doc ann #

Layout a document depending on which column it starts at. align is implemented in terms of column.

>>> column (\l -> "Columns are" <+> pretty l <> "-based.")
Columns are 0-based.
>>> let doc = "prefix" <+> column (\l -> "| <- column" <+> pretty l)
>>> vsep [indent n doc | n <- [0,4,8]]
prefix | <- column 7
    prefix | <- column 11
        prefix | <- column 15

punctuate #

Arguments

:: Doc ann

Punctuation, e.g. comma

-> [Doc ann] 
-> [Doc ann] 

(punctuate p xs) appends p to all but the last document in xs.

>>> let docs = punctuate comma (Util.words "lorem ipsum dolor sit amet")
>>> putDocW 80 (hsep docs)
lorem, ipsum, dolor, sit, amet

The separators are put at the end of the entries, which we can see if we position the result vertically:

>>> putDocW 20 (vsep docs)
lorem,
ipsum,
dolor,
sit,
amet

If you want put the commas in front of their elements instead of at the end, you should use tupled or, in general, encloseSep.

cat :: [Doc ann] -> Doc ann #

(cat xs) tries laying out the documents xs separated with nothing, and if this does not fit the page, separates them with newlines. This is what differentiates it from vcat, which always lays out its contents beneath each other.

>>> let docs = Util.words "lorem ipsum dolor"
>>> putDocW 80 ("Docs:" <+> cat docs)
Docs: loremipsumdolor

When there is enough space, the documents are put above one another:

>>> putDocW 10 ("Docs:" <+> cat docs)
Docs: lorem
ipsum
dolor
cat = group . vcat

fillCat :: [Doc ann] -> Doc ann #

(fillCat xs) concatenates documents xs horizontally with <> as long as it fits the page, then inserts a line' and continues doing that for all documents in xs. This is similar to how an ordinary word processor lays out the text if you just keep typing after you hit the maximum line length.

(line' means that if grouped, the documents are separated with nothing instead of newlines. See fillSep if you want a space instead.)

Observe the difference between fillSep and fillCat. fillSep concatenates the entries spaced when grouped:

>>> let docs = take 20 (cycle (["lorem", "ipsum", "dolor", "sit", "amet"]))
>>> putDocW 40 ("Grouped:" <+> group (fillSep docs))
Grouped: lorem ipsum dolor sit amet
lorem ipsum dolor sit amet lorem ipsum
dolor sit amet lorem ipsum dolor sit
amet

On the other hand, fillCat concatenates the entries directly when grouped:

>>> putDocW 40 ("Grouped:" <+> group (fillCat docs))
Grouped: loremipsumdolorsitametlorem
ipsumdolorsitametloremipsumdolorsitamet
loremipsumdolorsitamet

vcat :: [Doc ann] -> Doc ann #

(vcat xs) vertically concatenates the documents xs. If it is grouped, the line breaks are removed.

In other words vcat is like vsep, with newlines removed instead of replaced by spaces.

>>> let docs = Util.words "lorem ipsum dolor"
>>> vcat docs
lorem
ipsum
dolor
>>> group (vcat docs)
loremipsumdolor

Since grouping a vcat is rather common, cat is a built-in shortcut for it.

hcat :: [Doc ann] -> Doc ann #

(hcat xs) concatenates all documents xs horizontally with <> (i.e. without any spacing).

It is provided only for consistency, since it is identical to mconcat.

>>> let docs = Util.words "lorem ipsum dolor"
>>> hcat docs
loremipsumdolor

sep :: [Doc ann] -> Doc ann #

(sep xs) tries laying out the documents xs separated with spaces, and if this does not fit the page, separates them with newlines. This is what differentiates it from vsep, which always lays out its contents beneath each other.

>>> let doc = "prefix" <+> sep ["text", "to", "lay", "out"]
>>> putDocW 80 doc
prefix text to lay out

With a narrower layout, the entries are separated by newlines:

>>> putDocW 20 doc
prefix text
to
lay
out
sep = group . vsep

fillSep :: [Doc ann] -> Doc ann #

(fillSep xs) concatenates the documents xs horizontally with <+> as long as it fits the page, then inserts a line and continues doing that for all documents in xs. (line means that if grouped, the documents are separated with a space instead of newlines. Use fillCat if you do not want a space.)

Let's print some words to fill the line:

>>> let docs = take 20 (cycle ["lorem", "ipsum", "dolor", "sit", "amet"])
>>> putDocW 80 ("Docs:" <+> fillSep docs)
Docs: lorem ipsum dolor sit amet lorem ipsum dolor sit amet lorem ipsum dolor
sit amet lorem ipsum dolor sit amet

The same document, printed at a width of only 40, yields

>>> putDocW 40 ("Docs:" <+> fillSep docs)
Docs: lorem ipsum dolor sit amet lorem
ipsum dolor sit amet lorem ipsum dolor
sit amet lorem ipsum dolor sit amet

vsep :: [Doc ann] -> Doc ann #

(vsep xs) concatenates all documents xs above each other. If a group undoes the line breaks inserted by vsep, the documents are separated with a space instead.

Using vsep alone yields

>>> "prefix" <+> vsep ["text", "to", "lay", "out"]
prefix text
to
lay
out

grouping a vsep separates the documents with a space if it fits the page (and does nothing otherwise). See the sep convenience function for this use case.

The align function can be used to align the documents under their first element:

>>> "prefix" <+> align (vsep ["text", "to", "lay", "out"])
prefix text
       to
       lay
       out

Since grouping a vsep is rather common, sep is a built-in for doing that.

hsep :: [Doc ann] -> Doc ann #

(hsep xs) concatenates all documents xs horizontally with <+>, i.e. it puts a space between all entries.

>>> let docs = Util.words "lorem ipsum dolor sit amet"
>>> hsep docs
lorem ipsum dolor sit amet

hsep does not introduce line breaks on its own, even when the page is too narrow:

>>> putDocW 5 (hsep docs)
lorem ipsum dolor sit amet

For automatic line breaks, consider using fillSep instead.

concatWith :: Foldable t => (Doc ann -> Doc ann -> Doc ann) -> t (Doc ann) -> Doc ann #

Concatenate all documents element-wise with a binary function.

concatWith _ [] = mempty
concatWith (**) [x,y,z] = x ** y ** z

Multiple convenience definitions based on concatWith are already predefined, for example:

hsep    = concatWith (<+>)
fillSep = concatWith (\x y -> x <> softline <> y)

This is also useful to define customized joiners:

>>> concatWith (surround dot) ["Prettyprinter", "Render", "Text"]
Prettyprinter.Render.Text

(<+>) :: Doc ann -> Doc ann -> Doc ann infixr 6 #

(x <+> y) concatenates document x and y with a space in between.

>>> "hello" <+> "world"
hello world
x <+> y = x <> space <> y

tupled :: [Doc ann] -> Doc ann #

Haskell-inspired variant of encloseSep with parentheses and comma as separator.

>>> let doc = tupled (map pretty [1,20,300,4000])
>>> putDocW 80 doc
(1, 20, 300, 4000)
>>> putDocW 10 doc
( 1
, 20
, 300
, 4000 )

list :: [Doc ann] -> Doc ann #

Haskell-inspired variant of encloseSep with braces and comma as separator.

>>> let doc = list (map pretty [1,20,300,4000])
>>> putDocW 80 doc
[1, 20, 300, 4000]
>>> putDocW 10 doc
[ 1
, 20
, 300
, 4000 ]

encloseSep #

Arguments

:: Doc ann

left delimiter

-> Doc ann

right delimiter

-> Doc ann

separator

-> [Doc ann]

input documents

-> Doc ann 

(encloseSep l r sep xs) concatenates the documents xs separated by sep, and encloses the resulting document by l and r.

The documents are laid out horizontally if that fits the page:

>>> let doc = "list" <+> align (encloseSep lbracket rbracket comma (map pretty [1,20,300,4000]))
>>> putDocW 80 doc
list [1,20,300,4000]

If there is not enough space, then the input is split into lines entry-wise therwise they are laid out vertically, with separators put in the front:

>>> putDocW 10 doc
list [1
     ,20
     ,300
     ,4000]

Note that doc contains an explicit call to align so that the list items are aligned vertically.

For putting separators at the end of entries instead, have a look at punctuate.

indent #

Arguments

:: Int

Number of spaces to increase indentation by

-> Doc ann 
-> Doc ann 

(indent i x) indents document x by i columns, starting from the current cursor position.

>>> let doc = reflow "The indent function indents these words!"
>>> putDocW 24 ("prefix" <> indent 4 doc)
prefix    The indent
          function
          indents these
          words!
indent i d = hang i ({i spaces} <> d)

hang #

Arguments

:: Int

Change of nesting level, relative to the start of the first line

-> Doc ann 
-> Doc ann 

(hang i x) lays out the document x with a nesting level set to the current column plus i. Negative values are allowed, and decrease the nesting level accordingly.

>>> let doc = reflow "Indenting these words with hang"
>>> putDocW 24 ("prefix" <+> hang 4 doc)
prefix Indenting these
           words with
           hang

This differs from nest, which is based on the current nesting level plus i. When you're not sure, try the more efficient nest first. In our example, this would yield

>>> let doc = reflow "Indenting these words with nest"
>>> putDocW 24 ("prefix" <+> nest 4 doc)
prefix Indenting these
    words with nest
hang i doc = align (nest i doc)

align :: Doc ann -> Doc ann #

(align x) lays out the document x with the nesting level set to the current column. It is used for example to implement hang.

As an example, we will put a document right above another one, regardless of the current nesting level. Without alignment, the second line is put simply below everything we've had so far:

>>> "lorem" <+> vsep ["ipsum", "dolor"]
lorem ipsum
dolor

If we add an align to the mix, the vsep's contents all start in the same column:

>>> "lorem" <+> align (vsep ["ipsum", "dolor"])
lorem ipsum
      dolor

flatAlt #

Arguments

:: Doc ann

Default

-> Doc ann

Preferred when grouped

-> Doc ann 

By default, (flatAlt x y) renders as x. However when grouped, y will be preferred, with x as the fallback for the case when y doesn't fit.

>>> let doc = flatAlt "a" "b"
>>> putDoc doc
a
>>> putDoc (group doc)
b
>>> putDocW 0 (group doc)
a

flatAlt is particularly useful for defining conditional separators such as

softline = group (flatAlt hardline " ")
>>> let hello = "Hello" <> softline <> "world!"
>>> putDocW 12 hello
Hello world!
>>> putDocW 11 hello
Hello
world!

Example: Haskell's do-notation

Expand

We can use this to render Haskell's do-notation nicely:

>>> let open        = flatAlt "" "{ "
>>> let close       = flatAlt "" " }"
>>> let separator   = flatAlt "" "; "
>>> let prettyDo xs = group ("do" <+> align (encloseSep open close separator xs))
>>> let statements  = ["name:_ <- getArgs", "let greet = \"Hello, \" <> name", "putStrLn greet"]

This is put into a single line with {;} style if it fits:

>>> putDocW 80 (prettyDo statements)
do { name:_ <- getArgs; let greet = "Hello, " <> name; putStrLn greet }

When there is not enough space the statements are broken up into lines nicely:

>>> putDocW 10 (prettyDo statements)
do name:_ <- getArgs
   let greet = "Hello, " <> name
   putStrLn greet

Notes

Users should be careful to choose x to be less wide than y. Otherwise, if y turns out not to fit the page, we fall back on an even wider layout:

>>> let ugly = group (flatAlt "even wider" "too wide")
>>> putDocW 7 ugly
even wider

Also note that group will flatten y:

>>> putDoc (group (flatAlt "x" ("y" <> line <> "y")))
y y

This also means that an "unflattenable" y which contains a hard linebreak will never be rendered:

>>> putDoc (group (flatAlt "x" ("y" <> hardline <> "y")))
x

group :: Doc ann -> Doc ann #

(group x) tries laying out x into a single line by removing the contained line breaks; if this does not fit the page, or when a hardline within x prevents it from being flattened, x is laid out without any changes.

The group function is key to layouts that adapt to available space nicely.

See vcat, line, or flatAlt for examples that are related, or make good use of it.

hardline :: Doc ann #

A hardline is always laid out as a line break, even when grouped or when there is plenty of space. Note that it might still be simply discarded if it is part of a flatAlt inside a group.

>>> let doc = "lorem ipsum" <> hardline <> "dolor sit amet"
>>> putDocW 1000 doc
lorem ipsum
dolor sit amet
>>> group doc
lorem ipsum
dolor sit amet

softline' :: Doc ann #

softline' is like softline, but behaves like mempty if the resulting output does not fit on the page (instead of space). In other words, line is to line' how softline is to softline'.

With enough space, we get direct concatenation:

>>> let doc = "ThisWord" <> softline' <> "IsWayTooLong"
>>> putDocW 80 doc
ThisWordIsWayTooLong

If we narrow the page to width 10, the layouter produces a line break:

>>> putDocW 10 doc
ThisWord
IsWayTooLong
softline' = group line'

softline :: Doc ann #

softline behaves like space if the resulting output fits the page, otherwise like line.

Here, we have enough space to put everything in one line:

>>> let doc = "lorem ipsum" <> softline <> "dolor sit amet"
>>> putDocW 80 doc
lorem ipsum dolor sit amet

If we narrow the page to width 10, the layouter produces a line break:

>>> putDocW 10 doc
lorem ipsum
dolor sit amet
softline = group line

line' :: Doc ann #

line' is like line, but behaves like mempty if the line break is undone by group (instead of space).

>>> let doc = "lorem ipsum" <> line' <> "dolor sit amet"
>>> doc
lorem ipsum
dolor sit amet
>>> group doc
lorem ipsumdolor sit amet

line :: Doc ann #

The line document advances to the next line and indents to the current nesting level.

>>> let doc = "lorem ipsum" <> line <> "dolor sit amet"
>>> doc
lorem ipsum
dolor sit amet

line behaves like space if the line break is undone by group:

>>> group doc
lorem ipsum dolor sit amet

nest #

Arguments

:: Int

Change of nesting level

-> Doc ann 
-> Doc ann 

(nest i x) lays out the document x with the current nesting level (indentation of the following lines) increased by i. Negative values are allowed, and decrease the nesting level accordingly.

>>> vsep [nest 4 (vsep ["lorem", "ipsum", "dolor"]), "sit", "amet"]
lorem
    ipsum
    dolor
sit
amet

See also

  • hang (nest relative to current cursor position instead of current nesting level)
  • align (set nesting level to current cursor position)
  • indent (increase indentation on the spot, padding with spaces).

emptyDoc :: Doc ann #

The empty document behaves like (pretty ""), so it has a height of 1. This may lead to surprising behaviour if we expect it to bear no weight inside e.g. vcat, where we get an empty line of output from it (parens for visibility only):

>>> vsep ["hello", parens emptyDoc, "world"]
hello
()
world

Together with <>, emptyDoc forms the Monoid Doc.

unsafeViaShow :: Show a => a -> Doc ann #

Convenience function to convert a Showable value /that must not contain newlines/ to a Doc. If there may be newlines, use viaShow instead.

viaShow :: Show a => a -> Doc ann #

Convenience function to convert a Showable value to a Doc. If the String does not contain newlines, consider using the more performant unsafeViaShow.

data Doc ann #

The abstract data type Doc ann represents pretty documents that have been annotated with data of type ann.

More specifically, a value of type Doc represents a non-empty set of possible layouts of a document. The layout functions select one of these possibilities, taking into account things like the width of the output document.

The annotation is an arbitrary piece of data associated with (part of) a document. Annotations may be used by the rendering backends in order to display output differently, such as

  • color information (e.g. when rendering to the terminal)
  • mouseover text (e.g. when rendering to rich HTML)
  • whether to show something or not (to allow simple or detailed versions)

The simplest way to display a Doc is via the Show class.

>>> putStrLn (show (vsep ["hello", "world"]))
hello
world

Instances

Functor Doc

Alter the document’s annotations.

This instance makes Doc more flexible (because it can be used in Functor-polymorphic values), but fmap is much less readable compared to using reAnnotate in code that only works for Doc anyway. Consider using the latter when the type does not matter.

data FusionDepth #

Fusion depth parameter, used by fuse.

Constructors

Shallow

Do not dive deep into nested documents, fusing mostly concatenations of text nodes together.

Deep

Recurse into all parts of the Doc, including different layout alternatives, and location-sensitive values such as created by nesting which cannot be fused before, but only during, the layout process. As a result, the performance cost of using deep fusion is often hard to predict, and depends on the interplay between page layout and document to prettyprint.

This value should only be used if profiling shows it is significantly faster than using Shallow.

data SimpleDocStream ann #

The data type SimpleDocStream represents laid out documents and is used by the display functions.

A simplified view is that Doc = [SimpleDocStream], and the layout functions pick one of the SimpleDocStreams based on which one fits the layout constraints best. This means that SimpleDocStream has all complexity contained in Doc resolved, making it very easy to convert it to other formats, such as plain text or terminal output.

To write your own Doc to X converter, it is therefore sufficient to convert from SimpleDocStream. The »Render« submodules provide some built-in converters to do so, and helpers to create own ones.

Constructors

SFail 
SEmpty 
SChar !Char (SimpleDocStream ann) 
SText !Int !Text (SimpleDocStream ann)

length is O(n), so we cache it in the Int field.

SLine !Int (SimpleDocStream ann)

Int = indentation level for the (next) line

SAnnPush ann (SimpleDocStream ann)

Add an annotation to the remaining document.

SAnnPop (SimpleDocStream ann)

Remove a previously pushed annotation.

Instances

Instances details
Functor SimpleDocStream

Alter the document’s annotations.

This instance makes SimpleDocStream more flexible (because it can be used in Functor-polymorphic values), but fmap is much less readable compared to using reAnnotateST in code that only works for SimpleDocStream anyway. Consider using the latter when the type does not matter.

data PageWidth #

Maximum number of characters that fit in one line. The layout algorithms will try not to exceed the set limit by inserting line breaks when applicable (e.g. via softline').

Constructors

AvailablePerLine !Int !Double

Layouters should not exceed the specified space per line.

  • The Int is the number of characters, including whitespace, that fit in a line. A typical value is 80.
  • The Double is the ribbon with, i.e. the fraction of the total page width that can be printed on. This allows limiting the length of printable text per line. Values must be between 0 and 1, and 0.4 to 1 is typical.
Unbounded

Layouters should not introduce line breaks on their own.

uriToFilePath' :: Uri -> Maybe FilePath Source #

We use an empty string as a filepath when we don’t have a file. However, haskell-lsp doesn’t support that in uriToFilePath and given that it is not a valid filepath it does not make sense to upstream a fix. So we have our own wrapper here that supports empty filepaths.

readSrcSpan :: ReadS RealSrcSpan Source #

Parser for the GHC output format

type FileDiagnostic = (NormalizedFilePath, ShowDiagnostic, Diagnostic) Source #

Human readable diagnostics for a specific file.

This type packages a pretty printed, human readable error message along with the related source location so that we can display the error on either the console or in the IDE at the right source location.

data ShowDiagnostic Source #

Defines whether a particular diagnostic should be reported back to the user.

One important use case is "missing signature" code lenses, for which we need to enable the corresponding warning during type checking. However, we do not want to show the warning unless the programmer asks for it (#261).

Constructors

ShowDiag

Report back to the user

HideDiag

Hide from user

type IdeResultNoDiagnosticsEarlyCutoff v = (Maybe ByteString, Maybe v) Source #

an IdeResult with a fingerprint

type IdeResult v = ([FileDiagnostic], Maybe v) Source #

The result of an IDE operation. Warnings and errors are in the Diagnostic, and a value is in the Maybe. For operations that throw an error you expect a non-empty list of diagnostics, at least one of which is an error, and a Nothing. For operations that succeed you expect perhaps some warnings and a Just. For operations that depend on other failing operations you may get empty diagnostics and a Nothing, to indicate this phase throws no fresh errors but still failed.

A rule on a file should only return diagnostics for that given file. It should not propagate diagnostic errors through multiple phases.

modifyDynFlags :: GhcMonad m => (DynFlags -> DynFlags) -> m () Source #

Used to modify dyn flags in preference to calling setSessionDynFlags, since that function also reloads packages (which is very slow).

lookupPackageConfig :: Unit -> HscEnv -> Maybe UnitInfo Source #

Given a Unit try and find the associated PackageConfig in the environment.

textToStringBuffer :: Text -> StringBuffer Source #

Convert from the text package to the GHC StringBuffer. Currently implemented somewhat inefficiently (if it ever comes up in a profile).

printRdrName :: RdrName -> String Source #

Pretty print a RdrName wrapping operators in parens

printName :: Name -> String Source #

Pretty print a Name wrapping operators in parens

evalGhcEnv :: HscEnv -> Ghc b -> IO b Source #

Run a Ghc monad value using an existing HscEnv. Sets up and tears down all the required pieces, but designed to be more efficient than a standard runGhc.

moduleImportPath :: NormalizedFilePath -> ModuleName -> Maybe FilePath Source #

Given a module location, and its parse tree, figure out what is the include directory implied by it. For example, given the file /usr/Test/Foo/Bar.hs with the module name Foo.Bar the directory /usr/Test should be on the include path to find sibling modules.

readFileUtf8 :: FilePath -> IO Text Source #

Read a UTF8 file, with lenient decoding, so it will never raise a decoding error.

fingerprintToBS :: Fingerprint -> ByteString Source #

Convert a Fingerprint to a ByteString by copying the byte across. Will produce an 8 byte unreadable ByteString.

hDuplicateTo' :: Handle -> Handle -> IO () Source #

A slightly modified version of hDuplicateTo from GHC. Importantly, it avoids the bug listed in https://gitlab.haskell.org/ghc/ghc/merge_requests/2318.

traceAst :: (Data a, ExactPrint a, Outputable a, HasCallStack) => String -> a -> a Source #

Prints an Outputable value to stderr and to an HTML file for further inspection

printOutputable :: Outputable a => a -> Text Source #

Print a GHC value in defaultUserStyle without unique symbols.

This is the most common print utility, will print with a user-friendly style like: a_a4ME as a.

It internal using showSDocUnsafe with unsafeGlobalDynFlags.

diagFromErrMsg :: Text -> DynFlags -> MsgEnvelope DecoratedSDoc -> [FileDiagnostic] Source #

Produce a GHC-style error from a source span and a message.

srcSpanToRange :: SrcSpan -> Maybe Range Source #

Convert a GHC SrcSpan to a DAML compiler Range

srcSpanToFilename :: SrcSpan -> Maybe FilePath Source #

Extract a file name from a GHC SrcSpan (use message for unhelpful ones) FIXME This may not be an _absolute_ file name, needs fixing.

toDSeverity :: Severity -> Maybe DiagnosticSeverity Source #

Convert a GHC severity to a DAML compiler Severity. Severities below Warning level are dropped (returning Nothing).

diagFromStrings :: Text -> DiagnosticSeverity -> [(SrcSpan, String)] -> [FileDiagnostic] Source #

Produce a bag of GHC-style errors (ErrorMessages) from the given (optional) locations and message strings.

diagFromString :: Text -> DiagnosticSeverity -> SrcSpan -> String -> [FileDiagnostic] Source #

Produce a GHC-style error from a source span and a message.

noSpan :: String -> SrcSpan Source #

Produces an "unhelpful" source span with the given string.

zeroSpan Source #

Arguments

:: FastString

file path of span

-> RealSrcSpan 

creates a span with zero length in the filename of the argument passed

catchSrcErrors :: DynFlags -> Text -> IO a -> IO (Either [FileDiagnostic] a) Source #

Catch the errors thrown by GHC (SourceErrors and compiler-internal exceptions like Panic or InstallationError), and turn them into diagnostics

makeDefaultStderrRecorder :: MonadIO m => Maybe [LoggingColumn] -> Priority -> m (Recorder (WithPriority (Doc a))) Source #

withDefaultRecorder Source #

Arguments

:: MonadUnliftIO m 
=> Maybe FilePath

Log file path. Nothing uses stderr

-> Maybe [LoggingColumn]

logging columns to display. Nothing uses defaultLoggingColumns

-> Priority

min priority for hslogger compatibility

-> (Recorder (WithPriority (Doc d)) -> m a)

action given a recorder

-> m a 

If no path given then use stderr, otherwise use file. Kinda complicated because we also need to setup hslogger for `hie-bios` log compatibility reasons. If `hie-bios` can be set to use our logger instead or if `hie-bios` doesn't use hslogger then hslogger can be removed completely. See setupHsLogger comment.

IdeActions are used when we want to return a result immediately, even if it is stale Useful for UI actions like hover, completion where we don't want to block.

Run via runIdeAction.

data IdeState Source #

A Shake database plus persistent store. Can be thought of as storing mappings from (FilePath, k) to RuleResult k.

type IdeRule k v = (RuleResult k ~ v, ShakeValue k, Show v, Typeable v, NFData v) Source #

define :: IdeRule k v => Recorder (WithPriority Log) -> (k -> NormalizedFilePath -> Action (IdeResult v)) -> Rules () Source #

Define a new Rule without early cutoff

use :: IdeRule k v => k -> NormalizedFilePath -> Action (Maybe v) Source #

Request a Rule result if available

useWithStale :: IdeRule k v => k -> NormalizedFilePath -> Action (Maybe (v, PositionMapping)) Source #

Request a Rule result, it not available return the last computed result, if any, which may be stale

useWithStale_ :: IdeRule k v => k -> NormalizedFilePath -> Action (v, PositionMapping) Source #

Request a Rule result, it not available return the last computed result which may be stale. Errors out if none available.

useWithStaleFast :: IdeRule k v => k -> NormalizedFilePath -> IdeAction (Maybe (v, PositionMapping)) Source #

Lookup value in the database and return with the stale value immediately Will queue an action to refresh the value. Might block the first time the rule runs, but never blocks after that.

useWithStaleFast' :: IdeRule k v => k -> NormalizedFilePath -> IdeAction (FastResult v) Source #

Same as useWithStaleFast but lets you wait for an up to date result

useNoFile :: IdeRule k v => k -> Action (Maybe v) Source #

useNoFile_ :: IdeRule k v => k -> Action v Source #

uses_ :: IdeRule k v => k -> [NormalizedFilePath] -> Action [v] Source #

uses :: IdeRule k v => k -> [NormalizedFilePath] -> Action [Maybe v] Source #

Plural version of use

defineEarlyCutoff :: IdeRule k v => Recorder (WithPriority Log) -> RuleBody k v -> Rules () Source #

Define a new Rule with early cutoff

data IdeConfiguration Source #

Lsp client relevant configuration details

getFileContents :: NormalizedFilePath -> Action (UTCTime, Maybe Text) Source #

Returns the modification time and the contents. For VFS paths, the modification time is the current time.

getFileExists :: NormalizedFilePath -> Action Bool Source #

Returns True if the file exists

getAtPoint :: NormalizedFilePath -> Position -> IdeAction (Maybe (Maybe Range, [Text])) Source #

Try to get hover text for the name under point.

useE :: IdeRule k v => k -> NormalizedFilePath -> MaybeT IdeAction (v, PositionMapping) Source #

useE is useful to implement functions that aren’t rules but need shortcircuiting e.g. getDefinition.

getParsedModule :: NormalizedFilePath -> Action (Maybe ParsedModule) Source #

Parse the contents of a haskell file.

getClientConfigAction Source #

Arguments

:: Config

default value

-> Action Config 

Returns the client configurarion stored in the IdeState. You can use this function to access it from shake Rules
