Type of S-expressions
exception Not_found_s of tNot_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 * tOf_sexp_error (exn, sexp) the exception raised when an S-expression could not be
successfully converted to an OCaml-value.
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)val default_indent : int Pervasives.refdefault_indent reference to default indentation level for human-readable
conversions.
Initialisation value: 2.
val pp_hum : Format.formatter ‑> t ‑> unitpp_hum ppf sexp outputs S-expression sexp to formatter ppf in human readable
form.
val pp_hum_indent : int ‑> Format.formatter ‑> t ‑> unitpp_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 ‑> unitpp_mach ppf sexp outputs S-expression sexp to formatter ppf in machine readable
(i.e. most compact) form.
val to_string_hum : ?indent:int ‑> t ‑> stringto_string_hum ?indent sexp converts S-expression sexp to a
string in human readable form with indentation level indent.
!default_indentval to_string_mach : t ‑> stringto_string_mach sexp converts S-expression sexp to a string in
machine readable (i.e. most compact) form.
