Grow List sorting from a numeric-only insertion sort into a small, game-friendly toolkit that sorts records and query results by a key or a full comparator, stably and in O(n log n). - List.sort_by(s, keyfn) ascending by a key (draw order, price) - List.sort_desc_by(s, keyfn) descending (leaderboards) - List.sort_with(s, cmpfn) full cmp(a,b)->int comparator (multi-field) Comparators/keys are passed as named top-level functions rather than lambdas, so the toolkit ships without waiting on closures (#1). Engine: a stable bottom-up merge sort. emit_takeright is the single place stability is decided ("take the right run's head only on a strict win" -> equal keys keep prior order). List.sort becomes a hybrid: insertion sort for n<32, merge sort above; both stable, so output is unchanged. Key functions must return an integer-ish type; record slices hold pointer elements, so the key/comparator receives the record pointer. Tests: selfhost/tests/sort.ludic (scalar large-n, sort_by, sort_desc_by, stability, sort_with). Docs: list-sort_by/desc_by/with + updated list-sort. All suites green (28 self-host / 46 test / 29 test-tools); reseeded, C-free bootstrap fixpoint holds. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> |
