* * eval.c (rest_s, op_s): New variables.Kaz Kylheku2012-02-031-5/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | (do_eval_args): Allow calls specified by improper lists like (x y . z) where the z expression must evaluate to a list that turns into addition arguments to be applied. (transform_op, expand_op): New static functions. (expand): Call expand_op. (eval_init): Initialize rest_s and op_s. Use rest_s to register rest function. * lib.c (gensym): New function based on gensymv. (gensymv): Now calls gensym. * lib.h (gensym): Declared. * parser.l: Parse @ followed by digits as a new kind of token, METANUM. * parser.y (METANUM): New token. (meta_expr, exprs): Missing rlcp's added. (expr): METANUM variant introduced. (yybadtoken): Handle METANUM. * txr.1: Documented one-symbol argument list of lambda. Documented op. Closed some unbalanced parentheses. * txr.vim: Highlight op.
* * txr.1: UTF-8 handling clarified.Kaz Kylheku2012-02-021-12/+16

* * eval.c (lookup_sym_lisp1): New function.Kaz Kylheku2012-02-011-12/+48
| | | | | | | | | | | | | | | (do_eval, do_eval_args): New static functions. (eval, eval_args): Become wrappers for do_eval and do_eval_args, respectively. (eval_lisp1, eval_args_lisp1): New static functions. (dwim_loc, op_dwim): Use eval_lisp1 and eval_args_lisp1 instead of eval and eval_args. * parser.y (meta_expr): Bugfix: expand the whole dwim expression, rather than its arguments, which are not an expression. * txr.1: Updated with notes that dwim really does Lisp-1 style evaluation.
