Utility Module for S-expression Conversions
val default_string_of_float : (float ‑> string) Pervasives.refdefault_string_of_float reference to the default function used
to convert floats to strings.
Initially set to fun n -> sprintf "%.20G" n.
val write_old_option_format : bool Pervasives.refwrite_old_option_format reference for the default option format
used to write option values. If set to true, the old-style option
format will be used, the new-style one otherwise.
Initially set to true.
val read_old_option_format : bool Pervasives.refread_old_option_format reference for the default option format
used to read option values. Of_sexp_error will be raised
with old-style option values if this reference is set to false.
Reading new-style option values is always supported. Using a global
reference instead of changing the converter calling conventions is
the only way to avoid breaking old code with the standard macros.
Initially set to true.
val list_map : ('a ‑> 'b) ‑> 'a list ‑> 'b listWe re-export a tail recursive map function, because some modules
override the standard library functions (e.g. StdLabels) which
wrecks havoc with the camlp4 extension.

S-expression.

an S-expression. Uses conv to convert values of type 'a to an
S-expression.

an S-expression. Uses conv to convert values of type 'a to an
S-expression.

option to an S-expression. Uses conv to convert values of type
'a to an S-expression.
sexp_of_pair conv1 conv2 pair converts a pair to an S-expression.
It uses its first argument to convert the first element of the pair,
and its second argument to convert the second element of the pair.
sexp_of_triple conv1 conv2 conv3 triple converts a triple to
an S-expression using conv1, conv2, and conv3 to convert its
elements.
sexp_of_list conv lst converts the value lst of type 'a
list to an S-expression. Uses conv to convert values of type
'a to an S-expression.
sexp_of_array conv ar converts the value ar of type 'a
array to an S-expression. Uses conv to convert values of type
'a to an S-expression.
sexp_of_hashtbl conv_key conv_value htbl converts the value htbl
of type ('a, 'b) Hashtbl.t to an S-expression. Uses conv_key
to convert the hashtable keys of type 'a, and conv_value to
convert hashtable values of type 'b to S-expressions.
val sexp_of_opaque : 'a ‑> Sexp.tsexp_of_opaque x converts the value x of opaque type to an
S-expression. This means the user need not provide converters,
but the result cannot be interpreted.
val sexp_of_fun : ('a ‑> 'b) ‑> Sexp.tsexp_of_fun f converts the value f of function type to a
dummy S-expression. Functions cannot be serialized as S-expressions,
but at least a placeholder can be generated for pretty-printing.
exception Of_sexp_error of exn * Sexp.tOf_sexp_error (exn, sexp) the exception raised when an S-expression
could not be successfully converted to an OCaml-value.
val record_check_extra_fields : bool Pervasives.refrecord_check_extra_fields checks for extra (= unknown) fields
in record S-expressions.

unit.

char.

float.

int64.
val nativeint_of_sexp : Sexp.t ‑> nativeintnativeint_of_sexp sexp converts S-expression sexp to a value
of type nativeint.

function conv_key, which converts an S-expression to hashtable

Exception converters
val sexp_of_exn : exn ‑> Sexp.tsexp_of_exn exc converts exception exc to an S-expression.
If no suitable converter is found, the standard converter in
Printexc will be used to generate an atomic S-expression.
val sexp_of_exn_opt : exn ‑> Sexp.t optionsexp_of_exn_opt exc converts exception exc to Some sexp.
If no suitable converter is found, None is returned instead.
