Haskell Equivalent of OCaml's Format library

Question

Does Haskell have a library that does the same thing that OCaml's (Format library)? Or, what is the easiest way to pretty-print an abstract syntax tree in Haskell?

Thanks.

Answer 1

Is Text.PrettyPrint what you are looking for?

Answer 2

I really like using the wl-pprint package. It gives you loads of flexibility in very elegant code. See here for some nice documentation.

Answer 3

Text.Printf, i guess.
