Operations over S-expressions

since: 2.7

type t
type sexp = t

Re-exports

val atom : string -> t

Make an atom out of this string.

since: 2.8

val list : t list -> t

Make a Sexpr of this list.

since: 2.8

Constructors

val of_int : int -> t
val of_bool : bool -> t
val of_list : t list -> t
val of_rev_list : t list -> t: Reverse the list.

val of_float : float -> t
val of_unit : t
val of_pair : (t * t) -> t
val of_triple : (t * t * t) -> t
val of_quad : (t * t * t * t) -> t
val of_variant : string -> t list -> t: of_variant name args is used to encode algebraic variants into a S-expr. For instance of_variant "some" [of_int 1] represents the value Some 1.

val of_field : string -> t -> t: Used to represent one record field.

val of_record : (string * t) list -> t: Represent a record by its named fields.

Printing

val to_buf : Stdlib.Buffer.t -> t -> unit
val to_string : t -> string
val to_file : string -> t -> unit
val to_file_iter : string -> t iter -> unit: Print the given iter of expressions to a file.

val to_chan : Stdlib.out_channel -> t -> unit
val pp : Stdlib.Format.formatter -> t -> unit: Pretty-printer nice on human eyes (including indentation).

val pp_noindent : Stdlib.Format.formatter -> t -> unit: Raw, direct printing as compact as possible.

Parsing

type 'a parse_result = | Yield of 'a | Fail of string | End: A parser of 'a can return Yield x when it parsed a value, or Fail e when a parse error was encountered, or End if the input was empty.

module Decoder : sig ... end

val parse_string : string -> t or_error: Parse a string.

val parse_string_list : string -> t list or_error

Parse a string into a list of S-exprs.

since: 2.8

val parse_chan : Stdlib.in_channel -> t or_error: Parse a S-expression from the given channel. Can read more data than necessary, so don't use this if you need finer-grained control (e.g. to read something else after the S-exp).

val parse_chan_gen : Stdlib.in_channel -> t or_error gen: Parse a channel into a generator of S-expressions.

val parse_chan_list : Stdlib.in_channel -> t list or_error
val parse_file : string -> t or_error: Open the file and read a S-exp from it.

val parse_file_list : string -> t list or_error: Open the file and read a S-exp from it.
