| | | | | * mpi-patches/config-types: Added missing definitions of MP_DIGIT_SIZE in two cases.
* Bignum support, here we go!Kaz Kylheku2011-12-0926-137/+1140
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bignums, based on Michael Fromberger's MPI library, are integrated into the input syntax, stream output, equality testing, the garbage collector, and hashing. The plus operation handles transitions between fixnums and bignums. Other operations are still fixnum only. * Makefile (CFLAGS): Add mpi directory to include file search. (OBJS): Include new arith.o module and all of MPI_OBJS. (MPI_OBJS, MPI_OBJS_BASE): New variables. * configure (mpi_version, have_quilt, have_patch): New variables. Script detects whether patch and quilt are available. Unpacks mpi library, applies patches. Detects 128 bit integer type. Records more information in config.h about the sizes of types. * dep.mk: Updated. * depend.txr: Make work with paths that have directory components. * eval.c (eval_init): Rename of nump to fixnump. * gc.c (finalize, mark_obj): Handle BGNUM case. * hash.c: (hash_c_str): Changed to return unsigned long instead of long. (equal_hash): Handle BGNUM case. (eql_hash): Handle bignums with equal-hash, but other objects as eq. * lib.c (num_s): Variable renamed to fixnum_s. (bignum_s): New symbol variable. (code2type): Follow rename of num_s. Handle BGNUM case. (typeof): Follow rename of num_s. (eql): Handle bignums using equal, and other types using eq. (equal): Handle BGNUM case. (chk_calloc): New function. (c_num): Wording change in error message: is not a fixnum. (nump): Renamed to fixnump. (bignump): New function. (plus): Function removed, reimplemented in arith.c. (int_str): Handle integers which are too large for wcstol using bignum conversion. Base 0 is no longer passed to wcstol but converted to 10 because the special semantics for 0 would be inconsistent for bignums. (obj_init): Follow rename of num_s. Initialize bignum_s.
* C++ maintenance.Kaz Kylheku2011-12-083-4/+10
| | | | | | * eval.c (and_s, or_s): Redundant variables removed. * match.h (do_s): extern storage class specifier added.
* * eval.c (op_defun): Transform a function body by insertingKaz Kylheku2011-12-073-3/+77
| | | | | | | | a named block around it, thereby imitating a Common Lisp feature. (op_for): Establish an anonymous block around the loop body, test form and increment forms. * txr.1: Documented named block in defun. Documented for and for *.
* * txr.vim: Updated with all operators and functions.Kaz Kylheku2011-12-072-37/+43

* * txr.1: flip operator documented. Bad syntax for pop fixed.Kaz Kylheku2011-12-072-3/+16
| | | | Blank section for list-vector function added.
* * eval.c (op_modplace): If the operator is push, then reverseKaz Kylheku2011-12-072-9/+34
| | | | | | | the arguments. We want (push item list) for compatibility with CL. (expand): Bugfix: some of the cases were constructing new forms using unexpanded pieces from the original form. Added separate case for push, which handles the reversed arguments.
* * debug.c (debug): Fix regression: repeat last command by hittingKaz Kylheku2011-12-075-12/+80
| | | | | | | | | | | | | | | | | | | | | | | | Enter stopped working. This was broken by recent bugfixes in the string splitting functions, which introduced a semantics change. * eval.c (flip_s, vecref_s): New symbol variables. (op_modplace): New places (vecref ...) and (flip ...). Bugfix: dec operator was incrementing. (expand_place): Handle vecref and flip. Bugfix: pop has no third argument and so is now handled by the same case as flip. Bugfix: if a modify form has no third argument, then do not resynthesize it with a nil third argument. (eval_init): Initialize new symbol variables. Register new flip operator. Register new list_vectory function as intrinsic. * lib.c (rplacd): When modifying the cdr field of a lazy cons, then lapse the lazy function to nil! This is needed by user-defined lazy conses, and it makes sense to do it this way rather than put in some explicit interface. (list_vector): New function. * lib.h (list_vector): Declared.
* * eval.c (lookup_var, lookup_fun): Reversing assoc arguments.Kaz Kylheku2011-12-078-59/+124
| | | | | | | | | | | | | | | | | | | | | | | (eval_init): New intrinsics. * hash.c (struct_hash): assoc_fun parameters reversed. (gethash, gethash_f, gethash_n): Likewise. * lib.c (assoc, assq): Reversing parameters. (find_package, acons_new, acons_new_l, aconsq_new): Reversing arguments to assoc adn assq. * lib.h (assoc, assq): Declarations updated. * match.c (dest_set, dest_bind, h_var, h_coll, h_parallel, h_fun, subst_vars, do_txeval, v_next, v_parallel, v_gather, v_collect, v_flatten, v_cat, v_output, v_filter, f_fun, match_funcall): Reversing arguments to assoc. * unwind.c (uw_get_func, uw_exception_subtype_p, uw_register_subtype): Reversing arguments to assoc. * txr.1: Blank sections created for new functions.

* * parser.l: In the CHRLIT state, return a nonblank character as anKaz Kylheku2011-12-072-0/+10

* * eval.c (eval_init): New character functions registered.Kaz Kylheku2011-12-074-2/+106
| | | | | | | | | | | | | * lib.c (c_num): Generalized to convert characters to numbers also. This allows functions like gt and lt to work with characters. (chr_isalnum, chr_isalpha, chr_isascii, chr_iscntrl, chr_isdigit, chr_isgraph, chr_islower, chr_isprint, chr_ispunct, chr_isspace, chr_isupper, chr_isxdigit): New functions added. * lib.h: (chr_isalnum, chr_isalpha, chr_isascii, chr_iscntrl, * chr_isdigit, chr_isgraph, chr_islower, chr_isprint, chr_ispunct, * chr_isspace, chr_isupper, chr_isxdigit): New functions declared. (c_true): New macro.

* * eval.c (progn_s): New symbol variable.Kaz Kylheku2011-12-073-1/+32
| | | | | | | (op_progn): New static function. (eval_init): Initialize new variable, register progn operator. * txr.1: progn documented.
* Version 046txr-046Kaz Kylheku2011-12-065-4/+39
| | | | | | | | | | * txr.c (version): Bumped. * txr.1: Bumped version and set date. * configure (txr_ver): Bumped. * RELNOTES: Updated.
* * stream.c (find_char): New function.Kaz Kylheku2011-12-062-3/+28
| | | | | | | | | (string_in_get_line): Following up TODO. Fixed broken function. Now get_line on a string stream properly returns characters up to and not including the next newlne character, and also consumes the newline character. Other cases are handled properly, also: the stream being at EOF already, or at the last line not being newline-terminated.
* * eval.c (op_unwind_protect): Fixed uninitialized variableKaz Kylheku2011-12-069-22/+152
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | warning. (eval_init): New functions registered: typeof and vector functions, as well as length_list. * lib.c (length): Function renamed to length_list, because it is list specific. (length_vec, size_vec, vector_list): New functions. (length): New function, generic over lists, vectors and strings. * lib.h (length_list, length_vec, size_vec, vector_list): Declared. * match.c (h_var, h_fun, robust_length, v_deffilter, v_fun): Use length_list instead of length. * parser.l: Introduced # token. * parser.y (vector): New nonterminal. (expr): vector is a kind of expr. (chrlist): Bugfix: single-character syntax was not working; for instance #\x to denote the charcter x. (lit_char_helper): Use length_list instead of length. * stream.c (string_in_get_line): Bugfix: this was using the wrong length function: length was being applied to a string. The genericity of length makes that correct now, but changing to length_str anyway. * txr.1: Blank sections created for functions. Vector syntax documented.
