Haskell Equivalent to OCaml Format Library

Question

Does Haskell have a library that does the same as OCaml ( Format Library )? Or, what is the easiest way to print beautiful abstract syntax trees in Haskell?

Thanks.

Answer 1

I really enjoy using wl-pprint . This gives you flexibility in a very elegant code. See here for good documentation.

Answer 2

Is Text.PrettyPrint what you are looking for?

Answer 3

Text.Printf , I think.
