core: Stage 3 — leaf batch 2: sixteen more seed fns to the overlay; retire MIGRATION.md
key/val/select-keys/zipmap/merge/merge-with/get-in/memoize/partial/ trampoline/some?/true?/false?/max/min/reverse move to 20-coll.clj as the canonical Clojure definitions, plus find — which was previously missing from jolt entirely (select-keys/merge-with/memoize build on it). Two behavior fixes ride along: memoize now caches nil results (the kernel fn re-computed them — canonical find-based impl), and conj of nil onto a map is a no-op as in Clojure (it errored; the canonical merge relies on it). max/min keep the JVM NaN behavior by construction (pairwise >/<). not= stays: the kernel tier (subvec) uses it. One new tier-ordering rule, learned the hard way: a tier may only use macros from tiers that load BEFORE it — memoize's if-let (30-macros) broke compiled init while interpret mode passed, because compile expands macros at tier load and the interpreter expands lazily. Now documented in the migration workflow note. MIGRATION.md is gone — task tracking lives in beads (jolt-ded; the per-batch workflow, tier-order rules, perf wall, and remaining candidates are in bd memory core-migration-workflow). The doc's candidate lists had gone stale against the actual seed anyway. 43 new spec rows. Gate green: conformance 326x3, suite >= baseline, full jpm test, bench at parity with main back-to-back (4851 vs 4831 TOTAL).

# clojure.core migration worklist (jolt-1j0)
|
||||
|
||||
Tracking the move of clojure.core from native Janet (`src/jolt/core.janet`,
|
||||
4145 lines / 421 `core-*` fns) into the self-hosted Clojure overlay
|
||||
(`jolt-core/clojure/core/`). Goal: shrink the Janet seed to `core-renames` +
|
||||
genuinely host-coupled fns.
|
||||
|
||||
## Phase 0 classification (heuristic — validate per batch)
|
||||
|
||||
| Bucket | Count | Disposition |
|
||||
|---|---|---|
|
||||
| SEED (in `compiler/core-renames`) | 73 | stay in Janet (compiler emits `core-X` directly) |
|
||||
| MACRO (in `core-macro-names`) | 44 | Phase 3 |
|
||||
| HOST-coupled (atoms/vars/meta/proxy/transient/arrays/futures/ns/io) | 80 | Phase 4 (where feasible) / stay |
|
||||
| LAZY-coupled | 28 | Phase 5 |
|
||||
| MOVABLE pure-eager (candidates) | 193 | **Phase 2** |
|
||||
|
||||
Counts are heuristic (name + body markers); the MOVABLE list still has some
|
||||
host/lazy leakage (e.g. transient `assoc!`/`conj!`, `doall`/`dorun`,
|
||||
`chunk-*`, `deliver`) to filter out as each batch is actually moved.
|
||||
|
||||
**Key finding:** after removing SEED + HOST, the self-hosted compiler
|
||||
(`jolt-core/jolt/{ir,analyzer}.clj`) uses **no** additional clojure.core fns
|
||||
beyond the kernel tier (`second`/`peek`/`subvec`/`mapv`/`update`) plus host
|
||||
primitives (`atom`/`swap!`/`reset!`). So **Phase 1 (compiler-dep kernel tier)
|
||||
is essentially already complete** — to verify, not build.
|
||||
|
||||
## Performance baseline (test/bench/core-bench.janet, compile mode, min of 5, ms)
|
||||
|
||||
| bench | ms |
|
||||
|---|---|
|
||||
| fib | 128 |
|
||||
| seq-pipe | 88 |
|
||||
| reduce | 391 |
|
||||
| into-vec | 194 |
|
||||
| map-build | 681 |
|
||||
| map-read | 6 |
|
||||
| str-join | 244 |
|
||||
| hof | 604 |
|
||||
| **TOTAL** | **2336** |
|
||||
|
||||
Re-run after each phase; watch for regressions as fns move from native Janet to
|
||||
self-hosted Clojure (interpreted/compiled, slower than native primitives).
|
||||
|
||||
## Per-batch workflow + gate (every migration step)
|
||||
1. Canonical Clojure def in the overlay tier; remove the Janet `core-X` defn +
|
||||
its `core-bindings` entry (confirm leaf first: only defn+binding refs).
|
||||
2. **Add regression tests** for each moved fn — spec cases (test/spec/*-spec.janet,
|
||||
interpret) and, for any fn whose behavior is subtle or was buggy, a case in the
|
||||
3-mode conformance set (test/integration/conformance-test.janet).
|
||||
3. Gate: conformance ×3 modes · clojure-test-suite ≥ baseline · stage2==stage3
|
||||
fixpoint · fib compiled-fast · core-bench A/B under identical load (the
|
||||
absolute number is load-sensitive — compare batch-vs-prior back to back).
|
||||
|
||||
If a moved fn surfaces a latent bug (e.g. nthrest's nil-vs-() result, the
|
||||
if-let/when-let else-scope leak), fix it to match Clojure and add a regression
|
||||
test, rather than preserving the bug.
|
||||
|
||||
## Phase 2 batches landed
|
||||
|
||||
- **Sorted collections (jolt-0lj)** — sorted-map / sorted-map-by / sorted-set /
|
||||
sorted-set-by / sorted? / sorted-map? / sorted-set? / subseq / rsubseq are
|
||||
pure Clojure in their own tier (`25-sorted.clj`). Representation: tagged host
|
||||
table with a comparator-ordered :entries vector and the ops ATTACHED to the
|
||||
value (:ops map) — the seed dispatch branches call through (coll :ops), so no
|
||||
module-level hooks and the ops survive forks/AOT images. Host surface grew by
|
||||
two minimal value primitives: jolt.host/tagged-table and jolt.host/ref-get
|
||||
(raw field read — plain `get` on a sorted coll is the comparator lookup and
|
||||
would recurse). GOTCHA for future attached-ops ports: inside the overlay,
|
||||
NEVER read your own wrapper's fields with `get`.
|
||||
|
||||
- **Leaf batch (jolt-ded)** — complement, fnil (canonical 2/3/4-arity: patch
|
||||
the first 1-3 args only, unlike the old patch-everything kernel fn),
|
||||
clojure-version, bigdec, numerator, denominator, supers, munge, test moved
|
||||
to 20-coll.clj.
|
||||
- ***in* reader family (jolt-0d9)** — *in*, read-line, read, with-in-str,
|
||||
line-seq in a new `50-io.clj` tier over two seed seams (__stdin-read-line,
|
||||
__parse-next). GOTCHAS: a map LITERAL with :jolt/type as a key parses as a
|
||||
tagged form (don't tag overlay value maps); a leftover seed stub holding the
|
||||
same name breaks direct-linked overlay self-recursion (line-seq bound to the
|
||||
stub's root and truncated after one element) — delete the stub first.

|
||||
|
||||
## Phase 3 (macros) — status & findings
|
||||
|
||||
20 macros moved to the overlay: 19 user-facing in `30-macros.clj`, plus `when`
|
||||
in a new `00-syntax.clj` tier loaded **before** the kernel (interpreted defmacros,
|
||||
so the macros exist before any code that uses them compiles).
|
||||
|
||||
Macro-authoring toolkit for jolt (learned the hard way):
|
||||
- single-template hygiene: auto-gensym `foo#`
|
||||
- shared explicit fresh symbol: `(symbol (str (gensym)))` — a bare `(gensym)` in a
|
||||
macro body returns a *Janet* symbol the destructurer rejects
|
||||
- let-rebinding: splice binding *pairs* into a TEMPLATE vector (`[~a ~b ~@pairs]`),
|
||||
not a pre-built pvec value — `core-let` wants a tuple form
|
||||
- build sub-forms via templates, never `cons`/`list` (those make plists the
|
||||
evaluator can't run as a form)
|
||||
- Jolt `defmacro` is **single-arity** — use `& rest`/destructuring
|
||||
- syntax-tier macros may use only special forms + core-renames seed primitives
|
||||
|
||||
**Performance wall (the hot macros stay in Janet for now):** the load-order story
|
||||
works, but moving the *hot* fundamental control macros (`and`/`or`/`cond`/
|
||||
`when-not`) regressed the battery — as interpreted overlay defmacros they expand
|
||||
slower than native Janet, and since they appear in nearly every form the
|
||||
cumulative overhead tipped a heavy suite file over the 6 s per-file timeout
|
||||
(3930 -> 3911, +1 timeout). They are correct (conformance 228×3, all edge cases),
|
||||
but reverted. Moving `and/or/cond/when-not/case/doseq/declare/cond->/->/->>`
|
||||
needs a **fast (compiled) macro-expansion path**, not interpreted defmacros.
|
||||
|
||||
Deferred: `defn/defn-/fn/let/loop` (fundamental + same speed concern), the type
|
||||
machinery (`defrecord/defprotocol/extend-*/reify/proxy/definterface` → Phase 4),
|
||||
`lazy-seq/lazy-cat` (→ Phase 5).
