The `JSONPrinter` structure implements a printer for the
xref:str-JSON.adoc#type:value[`JSON.value`] type.

== Synopsis

== Interface

[source,sml]
------------
val print : TextIO.outstream * JSON.value -> unit
val print' : {strm : TextIO.outstream, pretty : bool} -> JSON.value -> unit
------------

== Description

`[.kw]#val# print : TextIO.outstream * JSON.value \-> unit`::
  `print (outS, jv)` prints the *JSON* value `jv` to the outstream `outS`
  in _condensed_ format (_i.e._, without newlines or indentation).

`[.kw]#val# print' : {strm : TextIO.outstream, pretty : bool} \-> JSON.value \-> unit`::
  `print' {outS, pretty} jv` prints the *JSON* value `jv` to the
  outstream `outS`, where the value of the `pretty` field controls whether
  the output is condensed (when `pretty` is `false`) or printed with
  new lines and indentation to improve readability (when `pretty` is `true`).
