JSON utilities

Simple (and not very robust) JSON generation utilities.

Everything is string based, creating lots of intermediate strings. Moreover, Json.string uses a custom string encoding based on the code for the format specifier %S, but with escapes for \u00HH instead of OCaml's \DDD.

Sourceval field : string -> string -> string

field name value creates a JSON field with the given name and value.

Sourceval string : string -> string

string value formats a string value as a JSON string.

Sourceval int : int -> string

int value formats an integer value as a JSON number.

Sourceval float : float -> string

float value formats a float value as a JSON number.

Sourceval object_ : string list -> string

object_ fields creates a JSON object from a list of field strings.

Sourceval array : string list -> string

array items creates a JSON array from a list of item strings.

Sourceval null : string

null is the JSON null literal.

Sourceval option : ('a -> string) -> 'a option -> string

option f opt formats an optional value as JSON. Returns the JSON null literal for None, or applies f to the value for Some v.
