Moreover, new such macros are easy to write, and + several new ones are already available. Moreover, new kinds of + assignable places are easy to create. + + * place.tl: New file. + + * lisplib.c, lisplib.h: New files. + + * Makefile (OBJS): New target, lisplib.o. + (GEN_HDRS): New variable. + (LISP_TO_C_STRING): New recipe macro, with rule. + (clean): Remove generated headers named in $(GEN_HDRS). + + * eval.c (dec_s, push_s, pop_s, flip_s, del_s): Variables removed. + (setq_s): New variable. + (lookup_var, lokup_sym_lisp_1, lookup_var_l, lookup_fun, lookup_mac, + lookup_symac, lookup_symac_lisp1): Trigger the delayed loading of + libraries for undefined global symbols, and re-try the lookup. + (op_modplace, dwim_loc, force_l): Static functions removed. + (op_setq): New static function. + (eval_init): Initialize setq_s; remove initializations of + removed variables; remove registrations for op_modplace; + add registration for sys:setq, sys:rplaca, sys:rplacd, + sys:dwim-set and sys:dwim-del intrinsics. + Call lisplib_init to initialize the dynamic library loading module. + + * lib.c (sys_rplaca, sys_rplacd): New functions, differing + in return value from rplaca and rplacd. + (ref, refset): Handle hash table. + (dwim_set, dwim_del): New functions. + + * lib.h (sys_rplaca, sys_rplacd, dwim_set, dwim_del): Declared. + + * genvim.txr: Include place.tl in scan. + + * tests/010/seq.txr: The del operator test + case no longer throws at run-time but at macro-expansion time, so the + test case is simply removed. + + * tests/010/seq.expected: Updated output. + + * tests/011/macros-2.txr: Reset *gensym-counter* to zero, because + the textual output of the test case includes gensyms, whose numberings + fluctuate with the content of the new Lisp library material. + + * tests/011/macros-2.expected: Updated output. + +2015-05-06 Kaz Kylheku <kaz@kylheku.com> + * gc.c (make_obj, gc): Move resetting of prev_malloc_bytes out of make_obj into gc. |
