Module Parsexp__.Import

default_string_of_float reference to the default function used to convert floats to strings.

Initially set to fun n -> sprintf "%.20G" n.

write_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.

read_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.

We 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.

sexp_of_unit () converts a value of type unit 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.

sexp_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.

sexp_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.

Of_sexp_error (exn, sexp) the exception raised when an S-expression could not be successfully converted to an OCaml-value.

record_check_extra_fields checks for extra (= unknown) fields in record S-expressions.

of_sexp_error reason sexp

raises Of_sexp_error

(Failure reason, sexp).

of_sexp_error exc sexp

raises Of_sexp_error

(exc, sexp).

unit_of_sexp sexp converts S-expression sexp to a value of type unit.

bool_of_sexp sexp converts S-expression sexp to a value of type bool.

string_of_sexp sexp converts S-expression sexp to a value of type string.

bytes_of_sexp sexp converts S-expression sexp to a value of type bytes.

char_of_sexp sexp converts S-expression sexp to a value of type char.

int_of_sexp sexp converts S-expression sexp to a value of type int.

float_of_sexp sexp converts S-expression sexp to a value of type float.

int32_of_sexp sexp converts S-expression sexp to a value of type int32.

int64_of_sexp sexp converts S-expression sexp to a value of type int64.

nativeint_of_sexp sexp converts S-expression sexp to a value of type nativeint.

ref_of_sexp conv sexp converts S-expression sexp to a value of type 'a ref using conversion function conv, which converts an S-expression to a value of type 'a.

lazy_t_of_sexp conv sexp converts S-expression sexp to a value of type 'a lazy_t using conversion function conv, which converts an S-expression to a value of type 'a.

option_of_sexp conv sexp converts S-expression sexp to a value of type 'a option using conversion function conv, which converts an S-expression to a value of type 'a.

pair_of_sexp conv1 conv2 sexp converts S-expression sexp to a pair of type 'a * 'b using conversion functions conv1 and conv2, which convert S-expressions to values of type 'a and 'b respectively.

triple_of_sexp conv1 conv2 conv3 sexp converts S-expression sexp to a triple of type 'a * 'b * 'c using conversion functions conv1, conv2, and conv3, which convert S-expressions to values of type 'a, 'b, and 'c respectively.

list_of_sexp conv sexp converts S-expression sexp to a value of type 'a list using conversion function conv, which converts an S-expression to a value of type 'a.

array_of_sexp conv sexp converts S-expression sexp to a value of type 'a array using conversion function conv, which converts an S-expression to a value of type 'a.

hashtbl_of_sexp conv_key conv_value sexp converts S-expression sexp to a value of type ('a, 'b) Hashtbl.t using conversion function conv_key, which converts an S-expression to hashtable key of type 'a, and function conv_value, which converts an S-expression to hashtable value of type 'b.

opaque_of_sexp sexp

raises Of_sexp_error

when attempting to convert an S-expression to an opaque value.

fun_of_sexp sexp

raises Of_sexp_error

when attempting to convert an S-expression to a function.

sexp_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.

sexp_of_exn_opt exc converts exception exc to Some sexp. If no suitable converter is found, None is returned instead.
