Functorized operations

This builds a parser and printer for S-expressions represented as in the Sexp argument.

  • since 2.7

Parameters

module Sexp : SEXP

Signature

type t = Sexp.t
type sexp = t
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

Reverse the list.

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 : Buffer.t -> t -> unit
val to_string : t -> string
val to_file : string -> t -> unit
val to_file_seq : string -> t CCSexp_intf.sequence -> unit

Print the given sequence of expressions to a file.

val to_chan : Pervasives.out_channel -> t -> unit
val pp : Format.formatter -> t -> unit

Pretty-printer nice on human eyes (including indentation).

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

Raw, direct printing as compact as possible.

Parsing

type 'a parse_result =
  1. | Yield of 'a
  2. | Fail of string
  3. | 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 CCSexp_intf.or_error

Parse a string.

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).

Parse a channel into a generator of S-expressions.

val parse_chan_list : Pervasives.in_channel -> t list CCSexp_intf.or_error
val parse_file : string -> t CCSexp_intf.or_error

Open the file and read a S-exp from it.

val parse_file_list : string -> t list CCSexp_intf.or_error

Open the file and read a S-exp from it.
