c++ - Handle exception as a parse error in bison -

how catch en exception thrown upon executing rule in bison like

foo : bar { $$ = new bar($1); } 

the bar constructor throws std::invalid_argument exception if it's argument inappropriate. catch exception , raise compilation error, native error message like

input:42.10: bad value `baz' bar 

also there lot of kind of rules, great handle not within rule itself, somewhere in parser.

if using lalr1.cc, c++ skeleton of bison, there limited support exceptions: if throw yy::parser::syntax_error, exception caught syntax error, duly reported, , parser enters error recovery mode. that's using yyerror.

if throw else, whole parsing aborted, stack cleaned, , exception rethrown. that's yyabort.

so if you'd errors caught rule-reduction should throw specific exception, see c++ parser interface documentation of bison.
