Type of S-expressions

val globalize : t -> t
val hash_fold_t : Base.Hash.state -> t -> Base.Hash.state
val hash : t -> Base.Hash.hash_value
include module type of Sexplib0.Sexp with type t := Sexplib0.Sexp.t
val t_of_sexp : Sexplib0.Sexp.t -> Sexplib0.Sexp.t
val sexp_of_t : Sexplib0.Sexp.t -> Sexplib0.Sexp.t
exception Not_found_s of Sexplib0.Sexp.t

Not_found_s is used by functions that historically raised Not_found, to allow them to raise an exception that contains an informative error message (as a sexp), while still having an exception that can be distinguished from other exceptions.

exception Of_sexp_error of exn * Sexplib0.Sexp.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 * Sexplib0.Sexp.t) list -> Sexplib0.Sexp.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 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 -> Sexplib0.Sexp.t -> unit

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

val pp_hum_indent : int -> Format.formatter -> Sexplib0.Sexp.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 -> Sexplib0.Sexp.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 -> Sexplib0.Sexp.t -> unit

Same as pp_mach.

Conversion to strings

val to_string_hum : ?indent:int -> Sexplib0.Sexp.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 : Sexplib0.Sexp.t -> string

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

val to_string : Sexplib0.Sexp.t -> string

Same as to_string_mach.

Styles

val of_float_style : [ `Underscores | `No_underscores ] ref
val of_int_style : [ `Underscores | `No_underscores ] ref
module Private = Sexplib0.Sexp.Private
val t_sexp_grammar : t Sexplib0.Sexp_grammar.t
val invariant : t -> unit
val of_string : unit

Base has never had an of_string function. We expose a deprecated of_string here so that people can find it (e.g. with merlin), and learn what we recommend. This of_string has type unit because we don't want it to be accidentally used.

  • deprecated [since 2018-02] Use [Parsexp.Single.parse_string_exn]

val (>=) : t -> t -> bool
val (<=) : t -> t -> bool
val (=) : t -> t -> bool
val (>) : t -> t -> bool
val (<) : t -> t -> bool
val (<>) : t -> t -> bool
val equal : t -> t -> bool
val compare : t -> t -> int

compare t1 t2 returns 0 if t1 is equal to t2, a negative integer if t1 is less than t2, and a positive integer if t1 is greater than t2.

val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~compare:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool

between t ~low ~high means low <= t <= high

val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).

val clamp : t -> min:t -> max:t -> t Base.Or_error.t
