A list of pretty printers for various types, for use in toplevels.
Pretty_printer has a
string list ref with the names of
pp functions matching the interface:
val pp : Format.formatter -> t -> unit
The names are actually OCaml identifier names, e.g., "Base.Int.pp". Code for building toplevels (this code is not in Base) evaluates the strings to yield the pretty printers and register them with the OCaml runtime.
module type S = sig ... end
Modules that provide a pretty printer will match
Register builds a
pp function from a
to_string function, and adds the
module_name ^ ".pp" to the list of pretty printers. The idea is to statically guarantee that one has the desired
pp function at the same point where the
name is added.
Register_pp is like
Register, but allows a custom
pp function rather than using
