-- {--}
-- import Text.InterpolatedString.Perl6 (q)
-- foo :: String
-- foo = [$q|
--
-- Well here is a
-- multi-line string!
--
-- |]
--
--
-- The qc form interpolates curly braces: Expressions inside {}
-- will be directly interpolated if it's a String, or have show
-- called if it is not.
--
-- Escaping of '{' is done with backslash.
--
-- For interpolating numeric expressions without an explicit type
-- signature, use the ExtendedDefaultRules language pragma, as shown
-- below:
--
--
-- {--}
-- import Text.InterpolatedString.Perl6 (qc)
-- bar :: String
-- bar = [$qc| Well {"hello" ++ " there"} {6 * 7} |]
--
--
-- bar will have the value " Well hello there 42 ".
--
-- If you want control over how show works on your types, define a
-- custom ShowQ instance:
--
-- -- import Text.InterpolatedString.Perl6 (qc, ShowQ(..)) -- instance ShowQ ByteString where -- showQ = unpack ---- -- That way you interpolate bytestrings will not result in double quotes -- or character escapes. module Text.InterpolatedString.Perl6 -- | QuasiQuoter for interpolating Haskell values into a string literal. -- The pattern portion is undefined. qc :: QuasiQuoter q :: QuasiQuoter class (Show a) => ShowQ a showQ :: (ShowQ a) => a -> String instance [overlap ok] Show StringPart instance [overlap ok] (Show a) => ShowQ a instance [overlap ok] ShowQ String instance [overlap ok] ShowQ Char
