(+|) :: FromBuilder b => Builder -> Builder -> b infixr 1

Concatenate, then convert.

Concatenate, then convert.

(||+) :: (Show a, FromBuilder b) => a -> Builder -> b infixr 1

show and concatenate, then convert.

(|++|) :: (Buildable a, FromBuilder b) => a -> Builder -> b infixr 1

(||++||) :: (Show a, FromBuilder b) => a -> Builder -> b infixr 1

(||++|) :: (Buildable a, FromBuilder b) => a -> Builder -> b infixr 1

(|++||) :: (Show a, FromBuilder b) => a -> Builder -> b infixr 1

fmt :: FromBuilder b => Builder -> b

fmt converts things to String, Text or Builder.

Most of the time you won't need it, as strings produced with (+|) and (|+) can already be used as String, Text, etc. However, combinators like listF can only produce Builder (for better type inference), and you need to use fmt on them.

Also, fmt can do printing:

>>> fmt "Hello world!\n"
Hello world!

fmtLn :: FromBuilder b => Builder -> b

Like fmt, but appends a newline.
