type string_source = Asai.Range.string_source = {title : string option;The title of a string source. A diagnostic handler can use the title of a string source in lieu of a file path.

type t = Asai.Range.tThe abstract type of ranges.
An auxiliary type to package data with an optional range.
make (beginning, ending) builds the range [beginning, ending) (not including the byte at the ending position) from a pair of positions beginning and ending. A range is empty if its beginning and ending positions are the same.
eof pos builds a special range referring to the end of the source. The input pos must be pointing at the end position; for example, if the position referring to a string source, pos.offset should be the length of the string.
view range returns a view of the range.
val begin_line_num : t -> intbegin_line_num range returns the 1-indexed line number of the beginning position.
val end_line_num : t -> intend_line_num range returns the 1-indexed line number of the ending position.
val begin_offset : t -> intbegin_offset range returns the 0-indexed offset of the (inclusive) beginning position.
val end_offset : t -> intend_offset range returns the 0-indexed offset of the (exclusive) ending position.
val title : source -> string optiontitle src gets the title of a string source or the path of a file source, or None if it does not exist.
val of_lex_position : ?source:source -> Lexing.position -> positionof_lex_position pos converts an OCaml lexer position pos of type Lexing.position into a position. The input pos must be byte-indexed. (Therefore, the OCaml tool ocamllex is compatible, but the OCaml library sedlex is not because it uses Unicode code points.)
val of_lex_range : ?source:source -> (Lexing.position * Lexing.position) -> tof_lex_range (begining, ending) takes a pair of OCaml lexer positions and creates a range. It is make (of_lex_position begining, of_lex_position ending).
val of_lexbuf : ?source:source -> Lexing.lexbuf -> tof_lexbuf lexbuf constructs a range from the current lexeme that lexbuf points to. It is of_lex_range (Lexing.lexeme_start_p lexbuf, Lexing.lexeme_end_p lexbuf).
val locate_lex :
?source:source ->
(Lexing.position * Lexing.position) ->
'a ->
'a locatedlocate_lex ps v is a helper function to create a value annotated with a range. It is locate (Some (of_lex_range ps)) v and is designed to work with the OCaml parser generator Menhir. You can add the following code to your Menhir grammar to generate annotated data:
%inline
locate(X):
| e = X
{ Asai.Range.locate_lex $loc e }Ugly printer for debugging
