Flow_sedlexing (melange.Js_parser.Flow

exception InvalidCodepoint(int);

This is a module provides the minimal Sedlexing suppport It is mostly a subset of Sedlexing with two functions for performance reasons:

exception MalFormed;

type apos = int;

type lexbuf;

let lexbuf_clone: lexbuf => lexbuf;

let from_int_array: array(int) => lexbuf;

let new_line: lexbuf => unit;

let next: lexbuf => option(Uchar.t);

let mark: lexbuf => int => unit;

let start: lexbuf => unit;

let backtrack: lexbuf => int;

let rollback: lexbuf => unit;

let lexeme_start: lexbuf => int;

let lexeme_end: lexbuf => int;

let loc: lexbuf => (int, int);

let lexeme_length: lexbuf => int;

let sub_lexeme: lexbuf => int => int => array(int);

let lexeme: lexbuf => array(int);

module Utf8: { ... };

let string_of_utf8: array(int) => string;

let current_code_point: lexbuf => int;

Two APIs used when we want to do customize lexing instead of using the regex based engine

let backoff: lexbuf => int => unit;

let set_lexeme_start: lexbuf => int => unit;
