[Caml-list] OCaml internal pretty-printing

[J.B. Domelevo]

I can't get any information about how Ocaml handles the pretty-printing of basic
values as lists or arrays. For instance :

let rec l = 0 :: l ;;

which builds an infinite list of zeros, is print until a certain point, and then
the interactive OCaml ends with "..."
The same occurs, of course, when Ocaml is given 'l;;'
Anyone knowing how the internal pretty-printer can be tuned or even turned on
and off ?
Thanks.

You should look to the Format module of the stdlib. Pretty printing is
done with it.
