* Fix missing nao terminator in formatted printing.Kaz Kylheku2017-03-131-4/+4
| | | | | | | | | | | | | | * arith.c (trunc1, trunc, floorf, ceili): Add missing nao terminator to uw_throwf calls. * debug.c (debug): Missing nao terminator in format call. * eval.c (expand_opt_params_rec, me_equot): Missing nao terminator in eval_error call. * lib.c (use_sym): Missing nao in uw_throw call. * regex.c (reg_derivative): Missing nao in uw_throwf.
* New floor-rem, ceil-rem and round-rem.Kaz Kylheku2017-02-261-7/+28
| | | | | | | | | | | | * arith.c (trunc_rem): Move function to below round function. Make second argument optional, defaulting to one. (floor_rem, ceil_rem, round_rem): New functions. * eval.c (eval_init): Registration of trunc-rem altered for optional argument. New registrations for floor-rem, ceil-rem, round=rem. * txr.1: Documented for new functions folded with trunc-rem.
* Second argument optional in trunc.Kaz Kylheku2017-02-251-0/+21
| | | | | | | | | | | | | | * arith.c (trunc1): New static function. (trunc): Detect a missing second argument and call func1. * eval.c (eval_init): Update registration of trunc intrinsic to make second arg optional. * txr.1: Describe optional argument of trunc. Trunc documentation is merged with the floor, ceil and round section. The mod and trunc-rem functions are split off into their own sections, leaving the / function described by itself. The documentation of / is substantially revised.
* Adding round function.Kaz Kylheku2017-02-251-0/+60
| | | | | | | | | | | * arith.c (round1): New static function. (roundiv): New function. * configure: New test for C99 round function. * eval.c (eval_init): Register round intrinsic. * txr.1: Documented.
* floor and ceil do division, with optional second arg.Kaz Kylheku2017-02-241-4/+177
| | | | | | | | | | | | | | | Also, with one argument, these functions handle ranges. * arith.c (floordiv, ceildiv): New functions. (floorf, ceili): Handle ranges. * eval.c (eval_init): Register floor and ceil to new functions. * lib.h (floordiv, ceildiv): Declared. * txr.1: Documentation updated.
* Add useful sys:bits function.Kaz Kylheku2017-02-041-0/+8
| | | | | | | | | | | | | | | | | | sys:bits converts a Lisp value to an integer whose value is the object's bit pattern interpreted as a pure binary number. (Only the "unboxed" part of the object that is stored in variables or passed into functions, not any "boxded" heap part which is referenced.) this holds: (eq a b) <--> (= (sys:bits a) (sys:bits b)) Two values a and b are the same object iff their sys:bits values are the same integer. * arith.c (bits): New static function. (arith_init): Register bits as sys:bits.

| | | | | | | | | | * arith.c (tofloatz, tointz): New functions. * arith.h (tofloatz, tointz): Declared. * eval.c (eval_init): Register tofloatz and tointz intrinsics. * txr.1: Documented new functions.
* Do not leave COBJ-ified mp_int uninitialized.Kaz Kylheku2016-06-081-0/+1
| | | | | | | | | | | | | | | Here we ensure that the digits pointer of an uninitialized mp_int is nulled out. The garbage collector could conceivably encounter such an object, in which case mp_clear will then try to free a garbage pointer. This could happen if an exception is thrown out of numeric code due to low memory, interrupting its execution, leaving behind an unfilled object produced by make_ubignum. * arith.c (make_ubignum): Perform minimal initialization of the mp_int using new function. * mpi/mpi.h (mp_init_minimal): New inline function.
* Fix leaks in use of MPI and within MPI.Kaz Kylheku2016-06-081-6/+6
| | | | | | | | | | | | | | | | * arith.c (logand, logior, logxor): Use make_ubignum to create an uninitialized bignum, because mp_and, mp_or, and mp_xor expect argument c to be uninitialized, and clobber it by initializing. (comp_trunc): Use make_ubignum for b argument, because mp_trunk_comp initializes it. (lognot, logtrunc): Use make_ubignum for b, because mp_trunc initializes it. * mpi/mpi.c (mp_and, mp_or, mp_xor, mp_comp, mp_trunc_comp, mp_trunc, mp_shift, mp_bit): Do not initialize the tmp that is passed as argument b to mp_2comp, since that function initializes it.
* New --free-all option for freeing memory on exit.Kaz Kylheku2016-06-071-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although we are garbage-collected, being able to clean up on shutdown is nevertheless useful for uncovering leaks. Leaks can occur, for instance, due to neglect to free out-of-heap satellite data from objects that are reclaimed by gc. This feature is long overdue. * arith.c, arith.h (arith_free_all): New function. * gc.c, gc.h (gc_free_all): New function. * lib.c (init): Remove program name parameter and redundant initialization of progname globl variable. * lib.h (progname): Superfluous declaration removed. This is already declared in txr.h. (init): Declaration updated. * regex.c (char_set_destroy): Do not check the static allocation flag here; just destroy the object. Do check for a null pointer, though. (char_set_cobj_destroy): This cobj destructor now checks the static flag of the char set object and avoids freeing it. Thus our char set singletons are left alone by gc, but our global freeing function takes care of them. (wide_cs): New static variable moved out of wide_display_char_p to static scope. (regex_free_all): New function. * regex.h (regex_free_all): Declared. * txr.c (progname): const qualifier and initializer removed. (main): Ensure progname is always dynamically allocated, even in the argv[0] == 0 case. Do not pass progname to init; it doesn't take that argument any more. (free_all): New static function. (txr_main): Implement --free-all option. * txr.h (progname): Declaration updated.
* Adding fixnum-min and fixnum-max variables.Kaz Kylheku2016-04-271-0/+2
| | | | | | | * arith.c (arith_init): Registered fixnum-min and fixnum-max variables. * txr.1: Documented.
* Fix ctype.h functions misapplied to wide characters.Kaz Kylheku2016-03-231-3/+3
| | | | | | | * arith.c (tofloat): The isdigit here should be iswdigit. Use '0' to '9' range check. (toint): Replace accidental isalpha and toupper with iswalpha and towupper.
* Functions for converting between buffers and integers.Kaz Kylheku2016-02-261-0/+31
| | | | | | | | | | | | | | | | | These functions convert between positive integers, and fixed-size memory buffers representing pure binary numbers in big endian byte order. This functionality will be used in some upcoming networking code. * arith.c (num_from_buffer, num_to_buffer): New functions. * arith.h (num_from_buffer, num_to_buffer): Declared. * mpi/mpi.c (mp_to_unsigned_buf): New function. * mpi/mpi.h (mp_to_unsigned_buf): Declared.

(c_uint_ptr_num): New function. (arith_init): Initialize UINT_PTR_MAX_MP. * arith.h (bignum_from_uintptr, c_uint_ptr_num): Declared. * eval.c (eval_init): Register random-state-get-vec. * mpi/mpi.c (mp_set_uintptr, mp_get_uintptr): New functions. (mp_set_intptr, mp_get_intptr): Expressed in terms of mp_set_uintptr and mp_get_uintptr. * mpi/mpi.h (mp_set_uintptr, mp_get_uintptr): Declared. * rand.c (make_random_state): Handle vector seed. (random_state_get_vec): New function. * rand.h (random_state_get_vec): Declared. * txr.1: Documented new feature in make-random-state and new random-state-get-vec function.

| | | | | | | | | | | | | | | | | | * configure (have_dbl_decimal_dig): New variable. New configure test to test for DBL_DECIMAL_DIG or __DBL_DECIMAL_DIG__, resulting in FLO_MAX_DIG macro being deposited in config.h. * arith.c (arith_init): Register flo-max-dig variable. * stream.c (print_flo_precision_s): New symbol variable.

* Stop using C library setjmp/longjmp.Kaz Kylheku2015-10-251-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TXR is moving to custom assembly-language routines. This is mainly motivated by a very dubious thing done in the GNU C Library setjmp and longjmp in the name of security. Evidently, glibc's setjmp "mangles" certain pointer values which are stored into the jmp_buf buffer. It's been that way since 2005, evidently. This means that, firstly, all along, the use of setjmp in gc.c to get registers into a buffer so they can be scanned has not actually worked properly. More importantly, this pointer mangling in setjmp and longjmp is very hostile to a stack copying implementation of delimited continuations. The reason is that continuations contain jmp_buf buffers, which get relocated in the process of capturing and reviving a continuation. Any pointers in a jmp_buf which point into the captured stack segment have to be fixed up to point into the relocated location. Mangled pointers make this difficult, requiring hacks which are specific to glibc and the machine architecture. We might as well implement a clean, well-behaved setjmp and longjmp. * Makefile (jmp.o): New object file. (dbg/%.o, opt/%.o): New rules for .S prerequisites. * args.c, arith.c, cadr.c, combi.c, cadr.c, combi.c, debug.c, eval.c, filter.c, glob.c, hash.c, lib.c, match.c, parser.c, rand.c, regex.c, signal.c, stream.c, struct.c, sysif.c, syslog.c, txr.c, unwind.c, utf8.c: Removed <setjmp.h> include. * gc.c: Switch to struct jmp and jmp_save, instead of jmp_buf and setjmp. * jmp.S: New source file. * signal.h (struct jmp): New struct type. (jmp_save, jmp_restore): New function declarations denoting assembly language routines in jmp.S. (extended_jmp_buf): Uses struct jmp instead of setjmp. (extended_setjmp): Use jmp_save instead of setjmp. (extended_longjmp): Use jmp_restore instead of longjmp.

The generic_funcall and apply functions are refactored for this, as are most functions that take variadic arguments. * args.c (args_add_list, args_cons_list): Functions removed. (args_normalize, args_normalize_fill): New functions. (args_get_checked): Draw arguments from list when array runs out. (args_copy, args_copy_zap): New functions. * args.h (ARGS_MAX): Reduced to 32.

The call intrinsic function binding now goes directly to generic_funcall. (list_star_intrinsic, interp_fun): Converted to struct args.

(eval_init): call_f initialized from generic_funcall rather than call. apply registered to applyv rather than apply_intrinsic.
