| | | | | | | | | | then unless opt_compat is 100 or less, provide a more consistent behavior, rather than splitting the string into characters. This latter behavior was never documented. * txr.1: Documented. * dep.mk: Updated.

(mark_obj): Under generational GC, if make_makefresh is in effect, set the generation to -1 on all marked objects. (sweep_one): In an EXTRA_DEBUGGING build, call breakpt if the object being swept is the one in break_obj. Under generational GC, place reachable objects that are in generation -1 the freshobj nursery and assign them to generation 0, rather than sticking them into the mature generation 1. (sweep): Under generational gc, reset the freshobj_idx variable here, so that sweep_one has an empty nursery in which to place the generation -1 objects. (prepare_finals, call_finals): New static functions. (gc): Call prepare_finals before sweep, and call call_finals just before re-enabling GC and returning. Do not reset freshobj_idx to zero; this was done in sweep, which may have added entries into it. (gc_finalize): New function. (gc_late_init): Register gc_finalize as intrinsic function finalize. * txr.1: Documented finalize. * HACKING: Documented finalization, described the additional meaning of the -1 generation, and added a section on debugging with break_obj and breakpt.

(struct hash_iter): New member, next. (reachable_iters): New static variable. (hash_mark): Reset the usecount of every reachable hash table.

(do_weak_tables): New static function. (do_iters): New static function. (hash_process_weak): Weak hash processing logic moved to do_weak_tables. Also calls do_iters. * txr.1: Describe hash table traversal, and the assurances and caveats about inserting and deleting items.

* * match.c (dest_bind): Remove the restriction of not allowingKaz Kylheku2014-10-171-0/+55
| | | | | | | | | | | @(expr ...) and @var on the left side of a bind. This is useful, and necessary for @(line @(lisp expr)) to work: matching computed line numbers and character positions. * txr.1: Document use of Lisp on left hand side of bind, that there is a restriction on the left hand side of a set, and that Lisp can be used in a line or chr directive for computed matches.
* Purge stray occurrences of "void *" from code base.Kaz Kylheku2014-10-171-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lib.c (cobj_print_op): In the format call, cast the C pointer to val, since the ~p conversion now takes a val rather than void *. (cptr_equal_op, obj_print, obj_pprint): Remove cast to void *, since obj now already has the type that ~p expects. * lib.h (struct any): Use mem_t * instead of void *. * parser.h (yyscan_t): Repeat the definition from inside the Flex-generated lex.yy.c. (yylex_init, yylex_destroy, yyget_extra, yyset_extra): Re-declare using yyscan_t typedef in place of void *. * parser.l (yyget_column, yyerrprepf): Re-declare using yyscan_t. (grammar): Use yyg in place of yyscanner in calls to yyerrprepf. * parser.y (yylex, %lex-param): Use yyscan_t instead of void *. (parse): Use yyscan_t for local variable. * signal.c (stack): Change type from void * to mem_t *. * stream.c (vformat): Conversion specifier p extracts val instead of void *. (run): Use casts that only remove const, not all the way to void *. * txr.1: Documented p conversion specifier of format. * Makefile (OBJS-y): Initialize with := to make sure it is a simple variable, and not a macro. (SRCS): New variable, listing source files. (enforce): New rule for enforcing coding conventions. Currently checks for void * occurrences.
* * arith.c (gcd): Fix semantics. If either operand isKaz Kylheku2014-10-161-25/+50
| | | | | | | | | | | | | | | | zero, return the other operand. (lcm): New function. * eval.c (eval_init): Retarget registration of gcd to variable argument gcdv function.

| | | | | | | | | | | | | * match.c (line_s): New variable. (h_chr, v_line): New static functions. (syms_init): line_s initialized. (dir_tables_init): Register v_line and h_chr. * match.h (line_s): Declared. * txr.1: Document @(line) and @(chr) directives. * txr.vim: Regenerated.
* * match.c (subst_vars): Fix buggy rendering of TXR Lisp expressionsKaz Kylheku2014-10-151-0/+15
| | | | | | | | | | | | | | | | | that evaluate to lists. For instance `@(list)` renders to the string "nil", and `@(list 1 2)` renders as "(1 2)". The desired behavior is "" and "1 2", respectively. (do_output_line): In output directives, there is a similar problem. A @(list) in the middle of an output block turns to nil, and a @(list 1 2) renders in parentheses as (1 2). Furthermore, there is the additional problem that no filtering is applied to the interpolated value. These behaviors are subject to the compatibility option, since they change the externally visible behavior of TXR programs. * txr.1: Document that empty lists in @(output) variable substitutions turn into nothing. Document value of 100 for -C option, describing the above issue.

GC-protect and initialize greater_f. * lib.h (greater_f): Declared.

| | | | | | | | | | | | | | | | | | | | | | | | | | (eval_init): Register less as intrinsic. Retarget merge intrinsic to merge_wrap for proper argument defaulting which is missing from merge, and which we don't want to introduce there since internal calls to merge don't erquire it. Change registration of sort so it has only one required argument, not two. * lib.c (less_f): New global variable. (less_tab): New static array. (less_tab_init): New static function. (less): New function. (sort): Default lessfun argument to the less function. (obj_init): GC-protect the less_f variable. Initialize it with a function object made from the less function.
