When a syntax error occurs, the current token is replaced with an [error] token. The parser then continues shifting and reducing, as far as possible. After (possibly) shifting the [error] token, though, the parser remains in error-handling mode, and does not request the next token, so the current token remains [error]. In OCaml's grammar, the [error] token always appears at the end of a production, and this production always raises an exception. In such a situation, the strategy described above means that: - either the parser will not be able to shift [error], and will raise [Parser.Error]; - or it will be able to shift [error] and will then reduce a production whose semantic action raises an exception. In either case, the parser will not attempt to read one token past the syntax error. *) let implementation = wrap Parser.Incremental.implementation and interface = wrap Parser.Incremental.interface and toplevel_phrase = wrap Parser.Incremental.toplevel_phrase and use_file = wrap Parser.Incremental.use_file and core_type = wrap Parser.Incremental.parse_core_type and expression = wrap Parser.Incremental.parse_expression and pattern = wrap Parser.Incremental.parse_pattern let module_type = wrap Parser.Incremental.parse_module_type let module_expr = wrap Parser.Incremental.parse_module_expr let longident = wrap Parser.Incremental.parse_any_longident let val_ident = wrap Parser.Incremental.parse_val_longident let constr_ident= wrap Parser.Incremental.parse_constr_longident let extended_module_path = wrap Parser.Incremental.parse_mod_ext_longident let simple_module_path = wrap Parser.Incremental.parse_mod_longident let type_ident = wrap Parser.Incremental.parse_mty_longident (* Error reporting for Syntaxerr *) (* The code has been moved here so that one can reuse Pprintast.tyvar *) module Style = Misc.Style let prepare_error err = let open Syntaxerr in match err with | Unclosed(opening_loc, opening, closing_loc, closing) -> Location.errorf ~loc:closing_loc ~sub:[ Location.msg ~loc:opening_loc "This %a might be unmatched" Style.inline_code opening ] "Syntax error: %a expected" Style.inline_code closing | Expecting (loc, nonterm) -> Location.errorf ~loc "Syntax error: %a expected."
