* New list-builder method: oust.Kaz Kylheku2022-02-231-0/+5
| | | | | | | | | | | | | | | | * autoload.c (build_set_entries): Add oust symbol. * stdlib/build.tl (list-builder postinit): Call the self argument self instead of bc, for consistency with other methods. (list-builder oust): New method. (list-builder-flets): Add local function oust. * tests/012/seq.tl: New tests. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* New function: partition-if.Kaz Kylheku2022-02-231-0/+26
| | | | | | | | | | | | | | | | * eval.c (eval_init): Register partition-if intrinsic. * lib.c (partition_if_countdown_funv, partition_if_func): New functions. (partition_if): New function. * lib.h (partition_if): Declared. * tests/012/seq.tl: New test cases. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* find-max: convert to seq_info iteration.Kaz Kylheku2022-02-221-0/+13
| | | | | | | | | | | | * lib.c (find_max): Simplify into a single loop rather than handling various sequence types specially. This means it works for all iterable objects now. * txr.1: find-max documentation updated; discussion of hash tables removed, since the described behavior is the one expected for hash tables as iterables. * tests/012/seq.tl: Add some test coverage.
* The pairlis function comes to TXR Lisp.Kaz Kylheku2021-12-221-0/+8
| | | | | | | | | | | | * eval.c (eval_init): Register pairlis intrinsic. * lib.c, lib.h (pairlis): New function. * tests/012/seq.tl: New test cases. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* New functions: subq, subql, subqual and subst.Kaz Kylheku2021-12-221-0/+50
| | | | | | | | | | | | | | | * eval.c (eval_init): Register new intrinsics. * lib.c, lib.h (subq, subql, subqual, subst): New functions. * tests/012/seq.tl: New test cases. * stdlib/optimize.tl (subst): Function removed. The new subst drop-in replaces this one. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* rot, nrot: new functions.Kaz Kylheku2021-12-071-0/+78
| | | | | | | | | | | | | | * eval.c (eval_init): nrot, rot intrinsics registered. * lib.c (nrot, rot): New functions. * lib.h (nrot, rot): Declared. * tests/012/seq.tl: New test cases. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* tuples*: new function.Kaz Kylheku2021-12-041-0/+47
| | | | | | | | | | | | | | | * eval.c (eval_init): Register tuples* intrinsic. * lib.c (tuples_star_func): New static function. (tuples_star): New function. * lib.h (tuples_star): Declared. * tests/012/seq.tl: New test cases. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* tuples: add test cases.Kaz Kylheku2021-12-021-1/+48
| | | | * tests/012/seq.tl: Numerous test cases for tuples.
* tuples: check length argument.Kaz Kylheku2021-12-021-0/+3
| | | | | | | * lib.c (tuples): Check that n argument giving tuple size is a is a positive integer. * tests/012/seql.tl: Test case added.
* lib: tests for keep-if, remove-if, separate.Kaz Kylheku2021-07-101-0/+42
| | | | * tests/012/seq.tl: New tests.
* lib: rmismatch tests and bugfix.Kaz Kylheku2021-06-221-0/+39
| | | | | | | * lib.c (rmismatch): when left is an empty string or vector, and right is nil: we must return -1 not zero. * tests/012/seq.tl: More rmismatch tests.
* lib: optimize mismatch, rmismatch for strings.Kaz Kylheku2021-06-221-0/+49
| | | | | | | | | | | * lib (mismatch, rmismatch): If the arguments are strings or literals, other than lazy strings, keyfun is identity, and equality is by character identity, the operation can be done with an efficient loop over the wchar_t strings. * tests/012/seq.tl: Tests for string case of mismatch, via starts-with function. Test mismatch via ends-with, and also directly for vectors and strings.
* reduce-left: rewrite using seq_iter.Kaz Kylheku2021-06-091-0/+10
| | | | | | | * lib.c (reduce_left): Use sequence iteration instead of list operations. * txr.1: Add a note to the documentation.
* window-map: add tests, improve doc, add examples.Kaz Kylheku2021-05-251-0/+19
| | | | | | | * tests/012/seq.tl: New tests. * txr.1: Improve documentation of window-map's :wrap and :reflect. Add examples.
* window-map: broken :wrap and :reflect.Kaz Kylheku2021-05-251-0/+33
| | | | | | | | | | | * lib.c (window_map_list): Rewrite :wrap and :reflect support. The main issue with these is that they only sample items from the front of the input list and generate both flanks of the boundary from that prefix; :reflect is additionaly buggy due to applying nreverse to a sub which can return the original sequence. * tests/012/seq.tl: Some test coverage for window-map.
* mapcar: add test covering recent regression.Kaz Kylheku2021-01-181-0/+3
| | | | | * test/012/seq.tl: New test with multiple lambda arguments and variadic function.
* tests: add tests for list-builder and fix bug.Kaz Kylheku2019-09-101-0/+10
| | | | | | | * share/txr/stdlib/build.tl (list-buider pend*): Fix typo: apply should be append. Funny, this didn't propagate to ncon*. * tests/012/seq.tl: Some list-builder tests via build macro.
* New tests for sequence manipulation.Kaz Kylheku2019-09-091-0/+9
Just a few append cases with improper lists here to start with. * tests/012/seq.tl: New file. * tests/012/seq.expected: New file
