of different parsers having different YYSTYPE unions that they want to use with it. I defined a new union core_YYSTYPE that is just the (very short) list of semantic values returned by the core scanner. I had originally worried that this would require an extra interface layer, but actually we can have parser.c's base_yylex (formerly filtered_base_yylex) take care of that at no extra cost. Names associated with the core scanner are now "core_yy_foo", with "base_yy_foo" being used in the core Bison parser and the parser.c interface layer. This solves the last serious stumbling block to eliminating plpgsql's separate lexer. One restriction that will still be present is that plpgsql and the core will have to agree on the token numbers assigned to tokens that can be returned by the core lexer. Since Bison doesn't seem willing to accept external assignments of those numbers, we'll have to live with decreeing that core and plpgsql grammars declare these tokens first and in the same order. |
