| | | | | cases like `@a@(foo)@b` where foo was being translated to (foo) rather than (sys:expr foo).
* * mpi-patches/shrink-mpi-int (mpi_int): Fixed terrible bug in thisKaz Kylheku2011-12-272-8/+12
| | | | | patch, resulting in an insufficient bit field width for representing the allocation size of the MPI integer on 32 bit platforms.
* * rand.c (make_state): Use ANSI C syntax for prototyped function of noKaz Kylheku2011-12-272-2/+8
| | | | | | arguments. This snuck through due to working with a C++ compiler. (random): Fixed unused variable warning that happens on 32-bit-pointer platforms.
* More formatting changes.Kaz Kylheku2011-12-251-267/+192

* * match.c (v_next): Change flatten to lazy_flatten in theKaz Kylheku2011-12-252-1/+7
| | | | | correct place. In the previous commit I did it in the code that handles the obsolescent :var syntax.
* * eval.c (eval_init): New function interned.Kaz Kylheku2011-12-256-3/+80
| | | | | | | | | | | | | * 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.
* * rand.c (rand32): Moved.Kaz Kylheku2011-12-232-21/+32
| | | | | | (make_random_state): After initializing, retrieve eight random numbers to clear pathological initial behavior leading to duplicate values.
* * arith.c (highest_bit): Changing to external linkage.Kaz Kylheku2011-12-234-20/+60
| | | | | | | | * arith.h (highest_bit): Declared. * rand.c (random): Rewrote using different algorithm which ensures even distribution, and avoids doing a bignum mod operation.

* * lib.c (memql): New function.Kaz Kylheku2011-12-234-5/+163
| | | | | | | | | | | (some_satisfy): Return the first non-nil result, rather than t. (all_satisfy): Return the value of the last item, if all items are processed. * lib.h (memql): Declared. * txr.1: Documented memq, memql, memqual, tree-find, some, all, none, eq, eql and equal.
* * txr.1: Documented copy-list, reverse, nreverse, ldiff and flatten.Kaz Kylheku2011-12-222-0/+107

* Bug #35010Kaz Kylheku2011-12-222-9/+26
| | | | | | | | | | * match.c (extract_bindings): Make sure there are no duplicate variables among the extracted bindings. This is needed because of the other changes. (do_output_line, do_output): In handling the rep/repeat directives, append the original bindings to the extracted set bindings for the variables which just occur in the clause, so that Lisp code can see all of the variables.
* * stream.c (vformat): If width is specified for ~s or ~a, andKaz Kylheku2011-12-222-1/+15
| | | | | | | the object is not a string or number, then print it to a string and treat it as a string, adjusting it within the field. Also, do not simply abort on an unknown format directive but throw a proper exception.
* * stream.c (vformat): Left-adjusted field is now specifiedKaz Kylheku2011-12-222-11/+15
| | | | | using < rather than '-'. The +, space and leading 0 are specified on the precision, not the width.
* * rand.c (random): Fix for 64 bit fixnums: stick two random numbersKaz Kylheku2011-12-222-0/+10
| | | | | together. Otherwise for fixnum moduli, we get only a 32 bit number no matter what the modulus is.
* * stream.c (vformat): Combine ~a and ~s cases, so numbers andKaz Kylheku2011-12-222-30/+12
| | | | | strings are printed the same way under ~s and ~a. The only difference is printing other kinds of objects.
* Bug #35026Kaz Kylheku2011-12-222-14/+45
| | | | | | | | | | | * stream.c (format_num): New argument: sign character. Rewrote to handle precision, width, zero padding and leading sign similarly to printf. (vformat): New syntax accepted: a space or + before the width specifies that a positive sign is to be explicitly written as a space or + character. Pass one more argument to vormat_num calls. Bugfix: go back to vf_init state after processing ~~.
* Bug #35136 and cleanup.Kaz Kylheku2011-12-222-32/+41
| | | | | | | | | | | * arith.c (plus, minus, mul, gt, ge, lt, le, exptmod, gcd): Remove trailing abort; we already marked uw_throwf as noreturn. This hack should not be needed in functions where the last statement is a throw. (trunc, expt): Repeated error case handled in one place. Temp variable used to avoid two calls to mp_clear. Call to abort removed. (mod): Repeated error handed in one place. Plugged memory leak by moving throw past mp_clear calls. Call to abort removed. (isqrt): Repeated error case handed in one place.
* * txr.vim: Fixed to char literal syntax.Kaz Kylheku2011-12-212-0/+5
|
* * mpi-patches/bit-search-optimizations (s_highest_bit):Kaz Kylheku2011-12-211-13/+13
| | | | | | It will take days to completely wipe the egg off my face. I forgot to fix this code for unsigned integers before pasting it into MPI.
* * arith.c (normalize): Linkage changed to extern.Kaz Kylheku2011-12-215-2/+21
| | | | | | | | * arith.h (normalize): Declared. * rand.c (random): Bugfix: normalize the bignum before returning it. * txr.1: Doc stubs for PRNG functionality.
* * rand.c: Added comment about source of algorithm.Kaz Kylheku2011-12-212-0/+8
|
* * rand.c (random): Bugfix: not building up sufficiently large bignums.Kaz Kylheku2011-12-212-3/+17
| | | | Work properly when mp_digit is smaller than 32 bits.
* * Makefile (OBJS): new object file, rand.o.Kaz Kylheku2011-12-216-1/+256
| | | | | | | | | | | | * 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.
* Bug #35139Kaz Kylheku2011-12-212-3/+12
| | | | | | | Better fix. * parser.y (YYEOF): If YYEOF is not defined, define it as zero. (yybadtoken): Undo previous changes: do not test for zero.
* Bug #35139Kaz Kylheku2011-12-212-3/+10
| | | | | * parser.y (yybadtoken): The current token (yychar) is 0 on byacc rather than YYEOF or YYEMPTY, so we have to handle that.
* * Makefile (distclean): use rm -rf on mpi directory.Kaz Kylheku2011-12-212-1/+6

* Test case for bug #35137Kaz Kylheku2011-12-203-0/+30
| | | | | | * tests/007/except-2.expected: New file. * tests/007/except-2.txr: New file.
* * eval.c (eval_init): New function registered.Kaz Kylheku2011-12-205-0/+44
| | | | | | | | * lib.c (cat_vec): New function. * lib.h (cat_vec): Declared. * txr.1: Documentation stub.
* Bug #35137Kaz Kylheku2011-12-203-11/+24
| | | | | | | | | | | | | | * unwind.c (uw_unwind_to_exit_point): When jumping to a catch frame, do not mark it invisible. * unwind.h (uw_catch): Flip the matches to nil so that this catch frame can no longer be identified as an unwind point by uw_throw, and thus will not be re-entered for the purposes of handling an exception. It remains visible for the purposes of running the clean up code. (uw_unwind): Prior to executing cleanup forms, flip the visibility to 0. This means that the frame will no longer be re-entered for any reason.
* Streamlining exception handling macros a little bit.Kaz Kylheku2011-12-204-13/+39
| | | | | | | | | | | | | | | | | | | | | | * 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.
* Critical regression. Hash lookup was crashing on some platformsKaz Kylheku2011-12-203-24/+40
| | | | | | | | | | | | | | due to negative hashing values being reduced modulo table size to a negative array index. * hash.c (equal_hash, eql_hash): Ensure that value returned is in the range [0,NUM_MAX]. (hash_obj): Unused function removed. (cobj_hash_op): Use hashing similar to eql hash for other kinds of references. (hash_eql, hash_equal): Removed bogus % NUM_MAX reduction. * hash.h (hash_obj): Declaration removed.
* * eval.c (eval_init): New functions registered as intrinsics.Kaz Kylheku2011-12-205-0/+68
| | | | | | | | * lib.c (copy_vec, sub_vec): New functions. * lib.h (copy_vec, sub_vec): Declared. * txr.1: Stub sections created.
* Version 049txr-049Kaz Kylheku2011-12-195-4/+64
| | | | | | | | | | * txr.c (version): Bumped. * txr.1: Bumped version and set date. * configure (txr_ver): Bumped. * RELNOTES: Updated.
* * eval.c (subst_vars, op_quasi_list, expand_quasi): New staticKaz Kylheku2011-12-194-4/+110
| | | | | | | | | | 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 Kylheku2011-12-186-16/+77
| | | | | | | | | | | | | | | | | (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.
* 2011-12-16 Kaz Kylheku <kaz@kylheku.com>Kaz Kylheku2011-12-162-11/+37
| | | | | | | | * hash.c (equal_hash): Eliminating displacement from character hashes. Simplifying some code. (eql_hash): Handle fixnums, characters and literals specially, rather than hashing all value types the same way. The shift applicable for object pointers causes adjacent integers to clash.
