Render
parenthesized :: ByteString -> ByteString #
Parenthesize a ByteString.
(<+>) :: ByteString -> ByteString -> ByteString #
Concatenate two ByteStrings with a space between.
commaSeparated :: [ByteString] -> ByteString #
Comma separate a list of ByteStrings.
doubleQuoted :: ByteString -> ByteString #
Add double quotes around a ByteString.
renderCommaSeparated :: SListI xs => (forall x. expression x -> ByteString) -> NP expression xs -> ByteString #
Comma separate the renderings of a heterogeneous list.
renderCommaSeparatedMaybe :: SListI xs => (forall x. expression x -> Maybe ByteString) -> NP expression xs -> ByteString #
renderNat :: KnownNat n => proxy n -> ByteString #
Render a promoted Nat.
