| | | | | | | | | | | | | | | assigning *stdout*, it really overwrites the underlying C variable. * eval.c (lookup_var): Handle new kind of toplevel binding. If the hash value is a cptr, it points to a val storage location. (lookup_val_l): New function. (op_modplace): Get location of variable using lookup_val_l rather than assuming there is a cons-based binding. (reg_var): Argument changed to val * pointer. Register the variable as a cptr referencing the location. (eval_init): reg_var calls pass address of each global. * eval.h (lookup_var_l): Declared.

| | | | | | | | | | | | | * lib.c:x (lazy_flatten_scan, lazy_flatten_func): New static functions. (lazy_flatten): New function. * lib.h (lazy_flatten): Declared. * match.c (v_next): Use lazy_flatten instead of flatten for processing a :list source. This means that @(next :list ...) can be used to process infinite lazy lists. * txr.1: Documented lazy-flatten.
* * Makefile (OBJS): new object file, rand.o.Kaz Kylheku2011-12-211-0/+7
| | | | | | | | | | | | * eval.c: Includes rand.h header. (eval_init): New variable and functions from rand module registered. * lib.c: Includes rand.h header. (init): Call rand_init. * rand.c: New file. * rand.h: New file.

* Streamlining exception handling macros a little bit.Kaz Kylheku2011-12-201-6/+3
| | | | | | | | | | | | | | | | | | | | | | * eval.c (op_unwind_protect): Use uw_simple_catch_begin, and remove the uw_catch (exsym, exvals) clause. Put explicit braces around the unwind code even though it is only one statement. * match.c (do_txeval): Got rid of empty uw_unwind clause. This is not needed any longer. (v_try): Got rid of explicit uw_do_unwind calls. * unwind.h (uw_simple_catch_begin): New macro. (uw_do_unwind): Macro removed. (uw_catch): Added goto uw_unwind_label at the front. This way if the previous clause falls through, control goes to the unwind logic. (uw_unwind): Got rid of initial break. Previous clause should fall through to unwind logic, whether it is the main clause, or one of the catches. (uw_catch_end): Default case aborts, because we don't expect this.
* * eval.c (eval_init): New functions registered as intrinsics.Kaz Kylheku2011-12-201-0/+2
| | | | | | | | * lib.c (copy_vec, sub_vec): New functions. * lib.h (copy_vec, sub_vec): Declared. * txr.1: Stub sections created.
* * eval.c (subst_vars, op_quasi_list, expand_quasi): New staticKaz Kylheku2011-12-191-0/+95
| | | | | | | | | | functions. (expand): New case for quasiliterals. (eval_init): Register quasi literal as special operator. * match.c (format_field): Linkage changed to external. * match.h (format_field): Declared. Declarations rearranged.
* * eval.c (bindings_helper): Fix format arguments.Kaz Kylheku2011-12-181-2/+13
| | | | | | | | | | | | | | | | | (eval_init): Registered new functions: symbol-function, func-get-form, func-get-env, functionp, interp-fun-p. * lib.c (nappend2, getplist_f, improper_plist_to_alist): tail variable renamed to avoid clash in macro. (func_get_form, func_get_env, interp_fun_p): New functions. * lib.h (func_get_form, func_get_env, interp_fun_p): Declared. (list_collect): Fix macro not to throw error, but handle the case. * match.c (vars_to_bindings, extract_bindings): tail variable renamed to avoid clash in macro. * txr.1: Documentation stubs.
* * eval.c (expand_vars): Bugfix: use expand_forms rather thanKaz Kylheku2011-12-161-1/+1
| | | | expand on a list of forms.
* * eval.c (eval_init): not added as synonym for null.Kaz Kylheku2011-12-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | * lib.c (copy_list): Use list_collect_append rather than list_collect_terminate. (append2, appendv): Simplified using new list_collect_append. (nappend2): Simplified using new list_collect_nconc. * lib.h (list_collect): Added check for accidental usage of list_collect after list_append, since PTAIL has different semantics. (list_collect_nconc, list_collect_append): Semantics fixed so that append collecting works more like the Common Lisp append function, allowing trailing atoms or a lone atom. The meaning of PTAIL is changed, however. Now PTAIL actually tracks the head of the most recently appended segment. Each append operation has to first traverse the previously added piece to get to the end. (list_collect_terminate): Macro removed. * match.c (v_gather): Removed useless use of list_collect_terminate. * parser.y: Some headers added that are needed by list_collect. * txr.1: Documented append, list, atom, null, not, consp, make-lazy-cons, lcons-fun, listp, proper-listp, length-list, mapcar, mappend, and apply.
* * eval.c (eval_init): Removed registration for vec_get_fil.Kaz Kylheku2011-12-141-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | Renamed vec_set_fill to vec-set-length. * hash.c (equal_hash): vec_fill to vec_length name change. (hash_grow, make_hash): No need to call vec_set_length. * lib.c (equal, vecref, vec_push, length_vec, list_vector, obj_print, obj_pprint): vec_fill to vec_length name change. (vector): Argument now represents actual length, not just allocated size. (vec_get_fill): Function removed; did exactly the same thing as length_vec. (vec_set_fill): Function renamed to vec_set_length. (vector_list): Allocate a 0 length vector initially. * lib.h (enum vecindex): member changes name from vec_fill to vec_length. (vector): Parameter name changed. (vec_set_fill): Redeclared. (vec_get_fill): Declaration removed. * txr.1: Doc stubs updated.

* Bignum support, here we go!Kaz Kylheku2011-12-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

(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 Kylheku2011-12-081-3/+1
| | | | | | * 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 Kylheku2011-12-071-2/+12
| | | | | | | | 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 *.
* * eval.c (op_modplace): If the operator is push, then reverseKaz Kylheku2011-12-071-9/+26
| | | | | | | 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 Kylheku2011-12-071-7/+33
| | | | | | | | | | | | | | | | | | | | | | | | 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 Kylheku2011-12-071-2/+17

| | | | | | * lib.c (chr_toupper, chr_tolower): New functions. * lib.h (chr_toupper, chr_tolower): New functions declared.
* * eval.c (eval_init): New character functions registered.Kaz Kylheku2011-12-071-0/+12
| | | | | | | | | | | | | * 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* * eval.c (op_cond): Fixed behavior for singleton clauses.Kaz Kylheku2011-12-051-8/+11
| | | | | | | | | | (eval_init): Use existing function objects car_f, cdr_f, eq_f, eql_f and equal_f. Added identity to function table. * lib.h (eql_f): Missing declaration added. * txr.1: Documented cond, and, if, or, defun, inc, dec, set, push and pop.
* * eval.c (op_qquote_error, op_unquote_error): New static functions.Kaz Kylheku2011-12-041-0/+19
| | | | | | | | | | | | | (expand_qquote): Bugfix: missing case added to handle directly quoted quasiquote. (eval_init): Error-catching pseudo-operators registered in op_table. * parser.y (force_regular_quotes): New function. (list): Quotes within unquotes and splices are regular. * txr.1: Clarified new rules. Removed description of ,'form and ,*'form special syntax.

| | | | | | | | | | | | | | variables. (op_unwind_protect, op_block, op_return, op_return_from): New static functions. (expand): Removed case for call, if, and, and or. These operators evaluate all their arguments, so the code walker can treat them as a function calls. Added case for block and return-from. (eval_init): New symbols interned. New operator functions registered in op_table. * txr.1: Blank sections added.
* * eval.c (eval_init): String and character functionsKaz Kylheku2011-12-031-1/+24

* * eval.c (expand_qquote): Bugfix: removed bogus recognitionKaz Kylheku2011-12-021-2/+0
| | | | | | and processing of regular quote form. This broke nested backquote processing, and quasiquote forms containing non-quasi-quotes like like '(a 'b ,c).
* * lib.h (or2): Restore macro version of or2, because we needKaz Kylheku2011-11-301-0/+2
| | | | | | | | | | | | | | | | | | | | the sequencing! Making it an inline function broke the tests. But we can't have multiple evaluation either, so it's going to use a temporary lexical variable. (uses_or2): Macro which declares the lexical variable needed by or2. * debug.c (debug): add uses_or2. * eval.c (eval_intrinsic, op_modplace): Likewise. * lib.c (lazy_str, lazy_str_force_upto, lazy_str_get_trailing_list): Likewise. * match.c (h_parallel, v_freeform, v_parallel, v_output): Likewise. * parser.y (unquotes_occur): Likewise. * stream.c (format): Likewise.

* * eval.c (dohash_s): New symbol variable.Kaz Kylheku2011-11-291-2/+44
| | | | | | | (op_dohash): New static function (expand): New case for dohash_s. Bugfix for do_s: expand was used rather than expand_forms. (eval_init): dohash_s initialized and entered into op_table.
* * eval.c (eval_init): hashp and maphash functions registered.Kaz Kylheku2011-11-291-0/+2
| | | | | | * hash.c (maphash): New function. * hash.h (maphash): Declared.

| | | | | | | | | | | | | | * eval.c (car_s, cdr_s): New symbol variables. (op_modplace): Cases for car and cdr added. (expand_place): Likewise. Calls abort should the cases fall through rather than returning 42. (expand): Bugfix: for and for* case not propagating source location info. Bugfix: expansion for do added. (eval_init): car_s and cdr_s initialized and used in place of previous intern calls. * parser.y (elem): Removed wrong logic for expanding the do form. It was expanding only the first argument.
* * eval.c (let_star_s, for_s, for_star_s): New symbols.Kaz Kylheku2011-11-281-12/+85
| | | | | | | | | | | | | (env_replace_vbind, bindings_helper): New static functions. (op_let): Refactored to allow for let* form. Code for setting up bindings moved into bindings helper, shared by for loop. (op_for, expand_vars): New static functions. (expand): Bugfix: let case was neglecting to walk the var initialization forms. This is done via expand_vars now. let_star_s added to this case to handle let* and let at the same time. New case added for for and for*. (eval_init): let_star_s, for_s, and for_star_s initialized, and entered into op_table.
