Text.Printer

Text monoid. string must be equivalent to fromString and be a monoid homomorphism, i.e. string mempty = mempty and mappend (string x) (string y) = string (mappend x y). Other operations must be monoid homomorphisms that are eqiuvalent (but possibly faster) to the composition of string and the corresponding embedding, e.g. text = string . unpack.

A simple string builder as used by Show.

Use this builder when you are sure that only ASCII characters will get printed to it.

UTF-8 lazy ByteString builder.

An alias for render . prettyPrinter

An associative operation.

Examples

>>> [1,2,3] <> [4,5,6][1,2,3,4,5,6]

>>> Just [1, 2, 3] <> Just [4, 5, 6]Just [1,2,3,4,5,6]

>>> putStr "Hello, " <> putStrLn "World!"Hello, World!

mconcat for Foldable data structures.

Combine the items of a Foldable data structure using the provided function. If the data structure is empty, mempty is returned.

Concatenate two Printers with a space between them.

Concatenate the items of a Foldable data structure with spaces between them.

A shorthand for fcat . separate.

Prepend all but the first element of a Traversable with the provided value, e.g. punctuateL p [x1, x2, ..., xN] = [x1, p <> x2, ..., p <> xN]

Append the provided value to all but the last element of a Traversable, e.g. punctuateR p [x1, ..., xN-1, xN] = [x1 <> p, ..., xN-1 <> p, xN]

Printers that can produce multiple lines of text.

Combine the items of a Foldable data structure with <->.
