Converting values into documents
text :: String -> DocSource
char :: Char -> DocSource
ptext :: String -> DocSource
int :: Int -> DocSource
integer :: Integer -> DocSource
float :: Float -> DocSource
double :: Double -> DocSource
rational :: Rational -> DocSource
Wrapping documents in delimiters
parens :: Doc -> DocSource
Wrap document in (...)
brackets :: Doc -> DocSource
Wrap document in [...]
braces :: Doc -> DocSource
Wrap document in {...}
quotes :: Doc -> DocSource
Wrap document in '...'
doubleQuotes :: Doc -> DocSource
Wrap document in "..."
Combining documents
(<>) :: Doc -> Doc -> DocSource
Beside
(<+>) :: Doc -> Doc -> DocSource
Beside, separated by space
hcat :: [Doc] -> DocSource
List version of <>
hsep :: [Doc] -> DocSource
List version of <+>
($$) :: Doc -> Doc -> DocSource
Above; if there is no overlap it "dovetails" the two
($+$) :: Doc -> Doc -> DocSource
Above, without dovetailing.
vcat :: [Doc] -> DocSource
List version of $$
sep :: [Doc] -> DocSource
Either hsep or vcat
cat :: [Doc] -> DocSource
Either hcat or vcat
fsep :: [Doc] -> DocSource
"Paragraph fill" version of sep
fcat :: [Doc] -> DocSource
"Paragraph fill" version of cat
nest :: Int -> Doc -> DocSource
Nested
hang :: Doc -> Int -> Doc -> DocSource
hang d1 n d2 = sep [d1, nest n d2]
punctuate :: Doc -> [Doc] -> [Doc]Source
punctuate p [d1, ... dn] = [d1 <> p, d2 <> p, ... dn-1 <> p, dn]
Predicates on documents
isEmpty :: Doc -> PprM BoolSource
Returns True if the document is empty
to_HPJ_Doc :: Doc -> DocSource
pprName :: Name -> DocSource
pprName' :: NameIs -> Name -> DocSource
