# Rendering

render :: HasChars a => Maybe Int -> Doc a -> a #

Synonym for `renderPlain`.

renderPlain :: HasChars a => Maybe Int -> Doc a -> a #

Render a `Doc` without using ANSI escapes. `renderPlain (Just n)` will use a line length of `n` to reflow text on breakable spaces. `renderPlain Nothing` will not reflow text.

renderANSI :: HasChars a => Maybe Int -> Doc a -> Text #

Render a `Doc` with ANSI escapes. `renderANSI (Just n)` will use a line length of `n` to reflow text on breakable spaces. `renderANSI Nothing` will not reflow text.

# Doc constructors

cr :: Doc a #

A carriage return. Does nothing if we're at the beginning of a line; otherwise inserts a newline.

blankline :: Doc a #

Inserts a blank line unless one exists already. (`blankline <> blankline` has the same effect as `blankline`.

blanklines :: Int -> Doc a #

Inserts blank lines unless they exist already. (`blanklines m <> blanklines n` has the same effect as `blanklines (max m n)`.

space :: Doc a #

A breaking (reflowable) space.

literal :: HasChars a => a -> Doc a #

Create a `Doc` from a stringlike value.

text :: HasChars a => String -> Doc a #

A literal string. (Like `literal`, but restricted to String.)

char :: HasChars a => Char -> Doc a #

A character.

prefixed :: IsString a => String -> Doc a -> Doc a #

Uses the specified string as a prefix for every line of the inside document (except the first, if not at the beginning of the line).

flush :: Doc a -> Doc a #

Makes a `Doc` flush against the left margin.

nest :: IsString a => Int -> Doc a -> Doc a #

Indents a `Doc` by the specified number of spaces.

hang :: IsString a => Int -> Doc a -> Doc a -> Doc a #

A hanging indent. `hang ind start doc` prints `start`, then `doc`, leaving an indent of `ind` spaces on every line but the first.

beforeNonBlank :: Doc a -> Doc a #

`beforeNonBlank d` conditionally includes `d` unless it is followed by blank space.

nowrap :: IsString a => Doc a -> Doc a #

Makes a `Doc` non-reflowable.

afterBreak :: Text -> Doc a #

Content to print only if it comes at the beginning of a line, to be used e.g. for escaping line-initial `.` in roff man.

lblock :: HasChars a => Int -> Doc a -> Doc a #

`lblock n d` is a block of width `n` characters, with text derived from `d` and aligned to the left.

cblock :: HasChars a => Int -> Doc a -> Doc a #

Like `lblock` but aligned centered.

rblock :: HasChars a => Int -> Doc a -> Doc a #

Like `lblock` but aligned to the right.

vfill :: HasChars a => a -> Doc a #

An expandable border that, when placed next to a box, expands to the height of the box. Strings cycle through the list provided.

nestle :: Doc a -> Doc a #

Removes leading blank lines from a `Doc`.

chomp :: Doc a -> Doc a #

Chomps trailing blank space off of a `Doc`.

inside :: Doc a -> Doc a -> Doc a -> Doc a #

Encloses a `Doc` inside a start and end `Doc`.

braces :: HasChars a => Doc a -> Doc a #

Puts a `Doc` in curly braces.

brackets :: HasChars a => Doc a -> Doc a #

Puts a `Doc` in square brackets.

parens :: HasChars a => Doc a -> Doc a #

Puts a `Doc` in parentheses.

quotes :: HasChars a => Doc a -> Doc a #

Wraps a `Doc` in single quotes.

doubleQuotes :: HasChars a => Doc a -> Doc a #

Wraps a `Doc` in double quotes.

bold :: HasChars a => Doc a -> Doc a #

Puts a `Doc` in boldface.

italic :: HasChars a => Doc a -> Doc a #

Puts a `Doc` in italics.

underlined :: HasChars a => Doc a -> Doc a #

Underlines a `Doc`.

strikeout :: HasChars a => Doc a -> Doc a #

Puts a line through a `Doc`.

fg :: HasChars a => Color -> Doc a -> Doc a #

Set foreground color.

bg :: HasChars a => Color -> Doc a -> Doc a #

Set background color.

type Color = Color8 #

black :: Color #

red :: Color #

green :: Color #

yellow :: Color #

blue :: Color #

magenta :: Color #

cyan :: Color #

white :: Color #

link :: HasChars a => Text -> Doc a -> Doc a #

Make Doc a hyperlink.

empty :: Doc a #

The empty document.

# Functions for concatenating documents

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

Concatenate a list of `Doc`s, putting breakable spaces between them.

($$) :: Doc a -> Doc a -> Doc a infixr 5 #

`a $$ b` puts `a` above `b`.

($+$) :: Doc a -> Doc a -> Doc a infixr 5 #

`a $+$ b` puts `a` above `b`, with a blank line between.

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

Concatenate documents horizontally.

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

Same as `hcat`, but putting breakable spaces between the `Doc`s.

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

List version of `$$`.

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

List version of `$+$`.

# Functions for querying documents

isEmpty :: Doc a -> Bool #

True if the document is empty.

offset :: (IsString a, HasChars a) => Doc a -> Int #

Returns the width of a `Doc`.

minOffset :: HasChars a => Doc a -> Int #

Returns the minimal width of a `Doc` when reflowed at breakable spaces.

updateColumn :: HasChars a => Doc a -> Int -> Int #

Returns the column that would be occupied by the last laid out character (assuming no wrapping).

height :: HasChars a => Doc a -> Int #

Returns the height of a block or other `Doc`.

charWidth :: Char -> Int #

Returns width of a character in a monospace font: 0 for a combining character, 1 for a regular character, 2 for an East Asian wide character. Ambiguous characters are treated as width 1.

realLength :: HasChars a => a -> Int #

Get real length of string, taking into account combining and double-wide characters. Ambiguous characters are treated as width 1.

realLengthNarrowContext :: HasChars a => a -> Int #

Get the real length of a string, taking into account combining and double-wide characters. Ambiguous characters are treated as width 1.

realLengthWideContext :: HasChars a => a -> Int #

Get the real length of a string, taking into account combining and double-wide characters. Ambiguous characters are treated as width 2.

realLengthNarrowContextNoShortcut :: HasChars a => a -> Int #

Like `realLengthNarrowContext`, but avoids optimizations (shortcuts). This is exposed for testing, to ensure that the optimizations are safe.

realLengthWideContextNoShortcut :: HasChars a => a -> Int #

Like `realLengthWideContext`, but avoids optimizations (shortcuts). This is exposed for testing, to ensure that the optimizations are safe.

# Char properties

isSkinToneModifier :: Char -> Bool #

Checks whether a character is a skin tone modifier.

isEmojiVariation :: Char -> Bool #

Checks whether a character is an emoji variation modifier.

isZWJ :: Char -> Bool #

Checks whether a character is a zero-width joiner.

# Utility functions

unfoldD :: Doc a -> [Doc a] #

Deprecated: unfoldD will be removed from the API.

Unfold a `Doc` into a flat list.

# Types

data Doc a #

Document, including structure relevant for layout.

Constructors

Text Int a | Text with specified width.
Block Int [Attributed a] | A block with a width and lines.

Flush (Doc a) | Doc laid out flush to left margin.
BreakingSpace | A space or line break, in context.
AfterBreak Text | Text printed only at start of line.
CarriageReturn | Newline unless we're at start of line.
