data Doc Source #

Instances

Eq Doc Source # 

Methods

(==) :: Doc -> Doc -> Bool #

(/=) :: Doc -> Doc -> Bool #

Show Doc Source # 

Methods

showsPrec :: Int -> Doc -> ShowS #

show :: Doc -> String #

showList :: [Doc] -> ShowS #

IsString Doc Source # 

Methods

fromString :: String -> Doc #

Monoid Doc Source # 

Methods

mempty :: Doc #

mappend :: Doc -> Doc -> Doc #

mconcat :: [Doc] -> Doc #

render :: IsString a => Maybe Int -> Doc -> a Source #

Renders a Doc. render (Just n) will use a line length of n to reflow text on breakable spaces. render Nothing will not reflow text.

cr :: Doc Source #

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

blankline :: Doc Source #

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

blanklines :: Int -> Doc Source #

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

space :: Doc Source #

A breaking (reflowable) space.

text :: String -> Doc Source #

A literal string.

char :: Char -> Doc Source #

A character.

prefixed :: String -> Doc -> Doc Source #

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 -> Doc Source #

Makes a Doc flush against the left margin.

nest :: Int -> Doc -> Doc Source #

Indents a Doc by the specified number of spaces.

hang :: Int -> Doc -> Doc -> Doc Source #

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 -> Doc Source #

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

nowrap :: Doc -> Doc Source #

Makes a Doc non-reflowable.

afterBreak :: String -> Doc Source #

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

offset :: Doc -> Int Source #

Returns the width of a Doc.

minOffset :: Doc -> Int Source #

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

height :: Doc -> Int Source #

Returns the height of a block or other Doc.

lblock :: Int -> Doc -> Doc Source #

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

cblock :: Int -> Doc -> Doc Source #

Like lblock but aligned centered.

rblock :: Int -> Doc -> Doc Source #

Like lblock but aligned to the right.

(<>) :: Monoid m => m -> m -> m infixr 6 #

An infix synonym for mappend.

Since: 4.5.0.0

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

Concatenate a list of Docs, putting breakable spaces between them.

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

a $$ b puts a above b.

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

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

isEmpty :: Doc -> Bool Source #

True if the document is empty.

empty :: Doc Source #

The empty document.

cat :: [Doc] -> Doc Source #

Concatenate a list of Docs.

hcat :: [Doc] -> Doc Source #

Same as cat.

hsep :: [Doc] -> Doc Source #

Same as cat, but putting breakable spaces between the Docs.

vcat :: [Doc] -> Doc Source #

List version of $$.

vsep :: [Doc] -> Doc Source #

List version of $+$.

nestle :: Doc -> Doc Source #

Removes leading blank lines from a Doc.

chomp :: Doc -> Doc Source #

Chomps trailing blank space off of a Doc.

inside :: Doc -> Doc -> Doc -> Doc Source #

Encloses a Doc inside a start and end Doc.

braces :: Doc -> Doc Source #

Puts a Doc in curly braces.

brackets :: Doc -> Doc Source #

Puts a Doc in square brackets.

parens :: Doc -> Doc Source #

Puts a Doc in parentheses.

quotes :: Doc -> Doc Source #

Wraps a Doc in single quotes.

doubleQuotes :: Doc -> Doc Source #

Wraps a Doc in double quotes.

charWidth :: Char -> Int Source #

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.

realLength :: String -> Int Source #

Get real length of string, taking into account combining and double-wide characters.
