Annotated (sexplib.Sexplib_

type pos = Sexplib.Pre_sexp.Annotated.pos = {

line : int;

col : int;

offset : int;

}

Position information for annotated S-expressions

type range = Sexplib.Pre_sexp.Annotated.range = {

start_pos : pos;

end_pos : pos;

}

Range information for annotated S-expressions

type t = Sexplib.Pre_sexp.Annotated.t =

| Atom of range * Sexplib.Type.t

| List of range * t list * Sexplib.Type.t

S-expression annotated with location information

type 'a conv = [

| `Result of 'a

| `Error of exn * t

]

Type of conversion results of annotated S-expressions.

exception Conv_exn of string * exn

Exception associated with conversion errors. First argument describes the location, the second the reason.

type stack = Sexplib.Pre_sexp.Annotated.stack = {

mutable positions : pos list;

mutable stack : t list list;

}

Stack used by annotation parsers

val get_sexp : t ‑> Sexplib.Type.t

get_sexp annot_sexp

Returns S-expression associated with annotated S-expression annot_sexp.

val get_range : t ‑> range

get_range annot_sexp

Returns the range associated with annotated S-expression annot_sexp.

val find_sexp : t ‑> Sexplib.Type.t ‑> t option

find_sexp annot_sexp sexp

Returns Some res where res is the annotated S-expression that is physically equivalent to sexp in annot_sexp, or None if there is no such S-expression.

val parse : ?parse_pos:Parse_pos.t ‑> ?len:int ‑> string ‑> (string, t) parse_result

parse ?parse_pos ?len str same as parse, but returns an S-expression annotated with location information.

val parse_bigstring : ?parse_pos:Parse_pos.t ‑> ?len:int ‑> bigstring ‑> (bigstring, t) parse_result

parse_bigstring ?parse_pos ?len str same as parse_bigstring, but returns an S-expression annotated with location information.

val input_sexp : ?parse_pos:Parse_pos.t ‑> Pervasives.in_channel ‑> t

input_sexp ?parse_pos ic like input_sexp, but returns an annotated S-expression instead.

val input_sexps : ?parse_pos:Parse_pos.t ‑> ?buf:string ‑> Pervasives.in_channel ‑> t list

input_sexps ?parse_pos ?buf ic like input_sexps, but returns a list of annotated S-expressions.

val input_rev_sexps : ?parse_pos:Parse_pos.t ‑> ?buf:string ‑> Pervasives.in_channel ‑> t list

input_sexps ?parse_pos ?buf ic like input_rev_sexps, but returns a list of annotated S-expressions.

NOTE: these functions should only be used if an annotated S-expression is required.

val load_sexp : ?strict:bool ‑> ?buf:string ‑> string ‑> t

load_sexp ?strict ?buf file like load_sexp, but returns an annotated S-expression.

val load_sexps : ?buf:string ‑> string ‑> t list

load_sexps ?buf file like load_sexps, but returns a list of annotated S-expressions.

val load_rev_sexps : ?buf:string ‑> string ‑> t list

load_rev_sexps ?buf file like load_rev_sexps, but returns a list of annotated S-expressions.

val of_string : string ‑> t

of_string str same as of_string, but returns an annotated S-expression.

val of_bigstring : bigstring ‑> t

of_bigstring bstr same as of_string, but operates on bigstrings.

val conv : (Sexplib.Type.t ‑> 'a) ‑> t ‑> 'a conv

conv f annot_sexp converts the S-expression associated with annotated S-expression annot_sexp using f.

Returns `Result res on success, or `Error (exn, sub_annot_sexp) otherwise, where exn is the exception associated with the conversion error, and sub_annot_sexp is the annotated S-expression on which conversion failed.

val get_conv_exn : file:string ‑> exc:exn ‑> t ‑> exn

get_conv_exn ~file ~exc annot_sexp

Returns the exception that would be raised for a given file and exception exc if conversion had failed on annotated S-expression annot_sexp. The format of the exception message is "file:line:col"
