Phase 14 fixes: pr-str mapping, every-pred, PLAN.md update
- compiler.janet: fix core-pr-str mapping — was pointing to core-str (line 221) - core.janet: add core-pr-str (string/format-based serialization with proper quoting), add core-every-pred (variadic predicate composition), wire both into core-bindings - cljs-port-5.janet: restore var-dynamic? test, with-meta preserves test, add pr-str keyword and every-pred assertions - PLAN.md: update to current state — all phases 0-14 checked off, 316/317 316 ok, 1 fail (pre-existing, unchanged)

REPL print-value uses buffer-based output: write-value/v buf appends formatted strings via buffer/push-string, then print-value creates buffer, builds string, and does a single (print (string buf)). This prevents Janet C runtime from interleaving native <tuple 0x...> output between prin statements in jpm build executables. Cond catch-all must use true clause: Janet's cond treats plain expressions as tests, so (push-str buf (string v)) at end of cond would be evaluated as a test — need true before it.

Protocol system: Type registry in context env (:type-registry) maps type-tag→proto-name→method-name→fn. Three dispatch special forms: protocol-dispatch (resolves method via registry or reified methods), register-method (stores impl in registry), make-reified (creates anonymous object with :jolt/protocol-methods). fn* forms emitted by extend-type/extend-protocol MUST be @[...] (array) for eval-list dispatch. Protocols are maps with :jolt/type :jolt/protocol and :methods map.

Janet `and` returns last truthy value, not boolean. `(and table? deftype)` returns the deftype string, not true. Predicate-like functions (core-map?, core-contains?, etc.) that check type tags via `(and ...)` must wrap in `(if ... true false)`. Hit us with core-map? returning the deftype string instead of boolean true for record instances. Also hit type-satisfies? which had to replace `(boolean ...)` (nonexistent) with `(if ... true false)`.

Examples: core-map? returning deftype string instead of boolean true for record instances. Also applies to type-satisfies? which must use `(if (and ...) true false)` — Janet has no `boolean` function.

Clojure .clj source files loaded via eval-form cannot have docstrings. If a defn form has 5 elements (defn, name, docstring, params, body), the evaluator's defn macro handler gets 4 args instead of 3, breaking with "macro arity mismatch". All .clj files in src/jolt/clojure/ must use 4-element defn forms: (defn name [params] body). Docstrings on defn are a Clojure feature not supported by Jolt's defn macro.

# Jolt — Complete Implementation Plan
|
||||
|
||||
## Architecture Goal
|
||||
|
||||
Minimal Janet bootstrap → SCI/CLJS Clojure source runs on Jolt.
|
||||
|
||||
Three layers:
|
||||
1. **Janet runtime**: types.janet, reader.janet, evaluator.janet, compiler.janet (~4,200 lines)
|
||||
2. **Clojure core**: core.janet (~1,400 lines), phm.janet (~200 lines)
|
||||
3. **Clojure source** (.clj files loadable at runtime): stdlib modules, SCI
|
||||
|
||||
## Current State
|
||||
|
||||
| Metric | Value |
|
||||
|--------|-------|
|
||||
| Total tests | 317 |
|
||||
| Passing | 316 |
|
||||
| Failing | 1 (lang.cljc deftype — deferred to Phase 15) |
|
||||
| CLJS test files ported | ~15/60 |
|
||||
| Total assertions | 860+ across 24 test files |
|
||||
| Source lines | ~5,600 (7 core .janet files) |
|
||||
|
||||
## Phase Plan
|
||||
|
||||
### Phase 0-10: Foundation ✓
|
||||
|
||||
| Phase | Description | Status |
|
||||
|-------|-------------|--------|
|
||||
| 0 | `defn` bug fix, bare symbol resolution | ✓ |
|
||||
| 1 | Var/Namespace system, ns form extensions | ✓ |
|
||||
| 2 | PersistentHashMap implementation | ✓ |
|
||||
| 3 | Var system: var-get/set/?, alter-var-root, intern, binding | ✓ |
|
||||
| 4 | deftype/defrecord completion | ✓ |
|
||||
| 5 | Multimethods + Hierarchy | ✓ |
|
||||
| 6 | Reader extensions: tagged literals, :jolt/tagged handler | ✓ |
|
||||
| 7 | LazySeq + PersistentHashSet | ✓ |
|
||||
| 8 | Protocol system: defprotocol, extend-type, extend-protocol, reify, satisfies? | ✓ |
|
||||
| 9 | REPL fixes: buffer-based output, collection rendering, cond fix | ✓ |
|
||||
| 10 | Standard Library: clojure.string, clojure.set, clojure.walk, clojure.zip, clojure.edn, clojure.java_io, jolt.interop, jolt.shell, jolt.http | ✓ |
|
||||
|
||||
### Phase 11: Fix Pre-existing Failures ✓
|
||||
|
||||
- `types.janet`: `ns?` now accepts both structs and tables
|
||||
- `core.janet`: `comment` macro wired into core-bindings
|
||||
- `sci/lang_stubs.clj`: minimal SCI type stubs for bootstrap
|
||||
- `test-load-sci.janet`: load stubs before SCI source files
|
||||
- **Result: SciVar fixed. 1 remaining (deftype with `#?@` — Phase 15)**
|
||||
|
||||
### Phase 12: Core Feature Completion ✓
|
||||
|
||||
- `apply` support in evaluator + compiler
|
||||
- `str` handles nil correctly
|
||||
- 6 CLJS test files created (~120 assertions)
|
||||
- `#()` anonymous fn reader with `%`, `%1`, `%2` arg handling
|
||||
|
||||
### Phase 13: Protocol Completion ✓
|
||||
|
||||
- reify dispatch: protocol methods work on reified objects
|
||||
- `#()` reader macro with gensym-based `%` arg handling
|
||||
- IFn protocol support in default invocation arm
|
||||
- clojure.walk loads and `keywordize-keys` works
|
||||
- 4 test sections: reify dispatch, anon fn, extend-type, walk loading
|
||||
|
||||
### Phase 14: Extend CLJS Ported Tests ✓
|
||||
|
||||
- `cljs-port-2.janet` expanded: 10 sections (12-21), 35→60 assertions
|
||||
- `cljs-port-5.janet` created: sections 22-24, destructuring, metadata, fn composition
|
||||
- `pr-str` compiler fix: maps to new `core-pr-str` (not `core-str`)
|
||||
- `every-pred` added to core.janet
|
||||
- `var-dynamic?` and `with-meta` tests restored
|
||||
|
||||
### Phase 15: SCI Bootstrap
|
||||
|
||||
- Complete `sci.lang` namespace with Var type
|
||||
- Load remaining SCI namespaces
|
||||
- SCI test runner
|
||||
- Fix SciVar `#?@` deftype issue
|
||||
|
||||
### Phase 16: Remaining Core Library + Tests
|
||||
|
||||
- Port ~20 remaining CLJS test files
|
||||
- Fix found gaps: `&` rest destructuring, `seq` nil handling, vector/list equality
|
||||
- `eval`, `syntax-quote` completion
|
||||
|
||||
### Phase 17: Optimization
|
||||
|
||||
- Compiler improvements: inline small core functions
|
||||
- PersistentHashMap dynamic bucket growth
|
||||
- Benchmarks
|
||||
|
||||
### Phase 18: Standard Library Completion
|
||||
|
||||
- Complete EDN reader/writer
|
||||
- Complete java.io wrappers
|
||||
- clojure.zip tests
|
||||
|
||||
## Implementation Order
|
||||
|
||||
1. ✅ Phases 0-14 (completed)
|
||||
2. Phase 15 (SCI bootstrap) — **critical path**
|
||||
3. Phase 16 (remaining test porting + feature gaps)
|
||||
4. Phases 17-18 (optimization, stdlib)
