2005-03-17 J. Tang * Added infinite recursion detection. It should work. 2004-10-29 J. Tang * Added more comments; upped version to 1.0. 2004-09-29 J. Tang * Added --version flag to display taccle version. * Added infix_calc.tac as example of how to do precedence. * Added operator precedence (%left, %right, %nonassoc, and %prec). Seems to work, at least with the example from the bison info manual. 2004-09-28 J. Tang * Discovered obscure error when calculating FIRST and FOLLOW sets given a rule of the form: x -> A x A (i.e., when the rule recurses with a terminal following the lhs token) * Added -w to enable warnings display. 2004-09-27 J. Tang * Added write_array procedure to better format state transition tables. Thanks to jcw for suggestion. 2004-09-08 J. Tang * As a result of working epsilons, added embedded actions. * Fixed epsilon transitions by adding FOLLOW sets. Double Woot! 2004-08-18 J. Tang * Added epsilon transitions. Woot! * Renamed synthesized attributes to just $1, $2... Renamed $yy_ to $_. (Yup, $_ like in Perl.) Thanks to Matt Newman for suggestion. * Added error terminal and error recovery (though no yyerrok). See interactive_calculator.tac example.
