Type of S-expressions

include module type of struct include Sexplib.Sexp end with type t := t
val equal : t -> t -> bool
exception Of_sexp_error of exn * t

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

Helpers

val message : string -> (string * t) list -> t

Helper to build nice s-expressions for error messages. It imitates the behavior of [%message ...] from the ppx_sexp_message rewriter.

message name key_values produces a s-expression list starting with atom name and followed by list of size 2 of the form (key value). When the key is the empty string, value is used directly instead as for [%message].

For instance the following code:

Sexp.message "error"
  [ "x", sexp_of_int 42
  ; "" , sexp_of_exn Exit
  ]

produces the s-expression:

(error (x 42) Exit)

Defaults

val default_indent : int Pervasives.ref

default_indent reference to default indentation level for human-readable conversions.

Initialisation value: 2.

Pretty printing of S-expressions

val pp_hum : Format.formatter -> t -> unit

pp_hum ppf sexp outputs S-expression sexp to formatter ppf in human readable form.

val pp_hum_indent : int -> Format.formatter -> t -> unit

pp_hum_indent n ppf sexp outputs S-expression sexp to formatter ppf in human readable form and indentation level n.

val pp_mach : Format.formatter -> t -> unit

pp_mach ppf sexp outputs S-expression sexp to formatter ppf in machine readable (i.e. most compact) form.

val pp : Format.formatter -> t -> unit

Same as pp_mach.

Conversion to strings

val to_string_hum : ?indent:int -> t -> string

to_string_hum ?indent sexp converts S-expression sexp to a string in human readable form with indentation level indent.

  • parameter indent

    default = !default_indent

val to_string_mach : t -> string

to_string_mach sexp converts S-expression sexp to a string in machine readable (i.e. most compact) form.

val to_string : t -> string

Same as to_string_mach.
