2005-03-17 J. Tang <tang@jtang.org>
* Added infinite recursion detection. It should work.
2004-10-29 J. Tang <tang@jtang.org>
* Added more comments; upped version to 1.0.
2004-09-29 J. Tang <tang@jtang.org>
* 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 <tang@jtang.org>
* 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 <tang@jtang.org>
* Added write_array procedure to better format state transition
tables. Thanks to jcw for suggestion.
2004-09-08 J. Tang <tang@jtang.org>
* As a result of working epsilons, added embedded actions.
* Fixed epsilon transitions by adding FOLLOW sets. Double Woot!
2004-08-18 J. Tang <tang@jtang.org>
* 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.
