This allows us to have + the /regex/ syntax in braces, but /regex/ is just a symbol + in the Lisp. The new #/ token is recognized and returned + as HASH_SLASH. All rules reformatted to a more easily + maintainble convention. + + * parser.y (HASH_SLASH): New token. + (modifiers, lisp_regex): New nonterminals. + (var): Grammar changed to use modifiers nonterminal instead of exprs. + (var_op): Rule moved closer to var. + (expr): Produces lisp_regex rather than regex. + (yybadtoken): Handle HASH_SLASH in the switch statement. + Bugfix: HASH_BACKSLASH was not handled. + + * txr.1: Documented #/regex/ syntax. + 2012-02-25 Kaz Kylheku <kaz@kylheku.com> * arith.c: Updated copyright year. |
