Phases 15-16: SCI bootstrap, Janet interop, eval, lazy-cat, CLJS ported tests
- SCI bootstrap complete: all 9 SCI source files load (317 forms, 0 failures) - prefer-method/remove-method/remove-all-methods promoted to special forms - eval special form (interpreter + compiler) with eval-test.janet - lazy-cat macro with structural equality tests in lazy-test.janet - Janet-native interop via . special form on tables/structs: field access (. obj :key), method calls (. obj method args...) fn* form compilation support, .- reader sugar interop-test.janet with 7 test sections (14 assertions) - New core bindings: with-meta, var-dynamic?, load-string - ^:dynamic def handler, core-str nil handling, core-meta for with-meta - 7 new CLJS ported test files: cljs-port-6 through -10, cljs-core-test, cljs-collections-test - test-sci-runtime.janet verifies SCI namespaces/types/Var/IBox/IVar - 317/317 tests pass, 0 failing scripts, 440+ assertions across 31 test files - README updated with Janet interop documentation

Janet's `eval` runs in Janet's default environment and does NOT have access to symbols imported via `(use ...)` in the calling file. `(eval '(core-inc 1))` fails with "unknown symbol core-inc" even when the file does `(use ./core)`. FIX: emit Janet data structures where function VALUES are embedded directly (e.g. `[core-inc 1]`) rather than source strings `"(core-inc 1)"`. The `core-fn-values` table resolves Janet symbol names to actual function values at compile time.

Jolt Compiler Architecture (Phases 1-6, dfa9874→1de109f): Two-phase — analyze-form (Clojure form → annotated AST) → emit-ast (→ Janet source string) or emit-expr (→ Janet data structures for eval). analyze-form takes [form bindings &opt ctx]; ctx needed for macro expansion. Symbol classification: bindings first (:local), then core-renames (:core-symbol), then plain (:symbol). Two emitter paths: string (compile-form) and data structures (compile-ast). Core fn values resolved via core-fn-values table. compile-and-eval takes [form ctx]; pass nil for no macro ctx.
|
||||
|
||||
Key naming/facts:
|
||||
- Clojure - → core-sub (NOT core--)
|
||||
- core-nth did not exist — had to add both the function and core-bindings entry
|
||||
- Missing from core-renames early: fn?, list, name, subs
|
||||
- Bare tuples in Janet eval → treated as function calls. Always emit (tuple ...) or ['tuple ...]
|
||||
- make-symbol: / at position 0 means unqualified symbol (was parsing empty ns)
|
||||
- raw-form->janet converter for quote: don't re-analyze quoted forms, pass through verbatim
|
||||
- emit-try-expr: Janet format is (try body ([err] handler)) not (try body (catch sym handler))
|
||||
- Loop compilation: (do (var _loop_N nil) (set _loop_N (fn [params] body)) (_loop_N init-vals...))
|
||||
- Recur compilation: rewrites to (loop-name arg1 arg2...) via :loop-name in AST
|
||||
|
||||
eval-string dispatch: When :compile? true, stateful forms (defmacro, ns, deftype, defmulti, defmethod, require, in-ns) use interpreter. All others (def, macros like defn) go through compile-and-eval. Macros expanded at analyze time via resolve-macro.
|
||||
|
||||
Remaining: syntax-quote, set! compiler support. deftype/defmulti/defmethod routed to interpreter.

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.

Post-Phase 13: 316/317 passing, 1 fail (pre-existing deftype in SCI lang.cljc, deferred to Phase 15). 8,000+ lines across ~25 source/test files. Key sources: compiler.janet (848), evaluator.janet (877), core.janet (1387), types.janet (441), reader.janet (500), phm.janet (199). 9 .clj stdlib modules (clojure/string.clj, set.clj, walk.clj, zip.clj, edn.clj, java_io.clj; jolt/interop.clj, shell.clj, http.clj). SCI stub file at src/jolt/clojure/sci/lang_stubs.clj provides 5 protocols + 3 deftypes. ~25 test files with 850+ assertions. CLJS-ported tests: 6 files, 27 sections, ~120 assertions. All builds/runs via `jpm test`.
|
||||
§
|
||||
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)`.
|
||||
§
|
||||
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.

TDD workflow for bootstrapping a Clojure interpreter on Janet
|
||||
|
||||
# Bootstrapping a Clojure interpreter on Janet
|
||||
|
||||
## Prerequisites
|
||||
- Janet ≥ 1.36, jpm
|
||||
- Target Clojure sources (e.g. sci) to load
|
||||
- Jolt sources in `src/jolt/`, tests in `test/`
|
||||
|
||||
## TDD Loop
|
||||
1. Write a failing test in `test/<feature>-test.janet` using `(use ../src/jolt/...)` relative paths
|
||||
2. Run with `janet test/<file>.janet` (faster than `jpm test` for iteration)
|
||||
3. If test involves `init` (which loads clojure.core), also `(use ../src/jolt/api)`
|
||||
4. Implement in `src/jolt/<module>.janet`
|
||||
5. Run test → see failure message → fix → repeat
|
||||
6. After passing: `jpm test` to ensure no regressions
|
||||
|
||||
## Current bootstrap progress
|
||||
|
||||
**All files parse cleanly. Eval status:**
|
||||
|
||||
| File | Forms | Eval OK | Failures |
|
||||
|------|-------|---------|----------|
|
||||
| sci.impl.macros | 4/4 | 4 | 0 |
|
||||
| sci.impl.protocols | 15/17 | 15 | 2 (resolution stubs) |
|
||||
| sci.impl.utils | 39/47 | 39 | 8 (multi-arity, missing deps) |
|
||||
| sci.impl.types | 22/27 | 22 | 5 (resolution stubs) |
|
||||
| sci.impl.unrestrict | 2/2 | 2 | 0 |
|
||||
| sci.impl.vars | 28/28 | 28 | 0 |
|
||||
| sci.lang | 10/10 | 10 | 0 |
|
||||
| sci.ctx-store | 6/6 | 6 | 0 |
|
||||
| sci.impl.namespaces | 93/98 | 93 | 5 (missing copy-core-var dep) |
|
||||
| sci.core | 60/69 | 60 | 4 (*1/*2/*3/*e unresolved) |
|
||||
|
||||
**Loading order:** macros → protocols → types → unrestrict → vars(27/28, skip comment block) → lang → utils → ctx-store → namespaces → core
|
||||
|
||||
**Added special forms:** quote, syntax-quote, unquote, unquote-splicing, do, if, def, defmacro, fn*, let*, loop*, recur, throw, try, set!, var, locking, instance?, defmulti, defmethod, deftype, new, . (22 total)
|
||||
|
||||
**Core additions:** when (macro), defn (macro with docstring), declare (macro), fn (macro — wraps fn*), Object (interop stub), derive, isa?, ancestors, descendants (hierarchy stubs), defprotocol (macro), extend-type, extend-protocol (macro), extend (macro), reify, satisfies?, extends?, implements?, type->str, comment (macro), prefer-method (stub), *unchecked-math* (false), *clojure-version* ({:major 1 :minor 11})
|
||||
|
||||
**Reader:** `#?(:clj ...)`, `#?@(:clj ...)` with splicing, `#_` discard, `#\` var-quote, `^` metadata, `;` comments → skip, nil `#?(:cljs ...)` → skip (non-splicing), empty `#?@(:cljs ...)` → empty splice, unmatched `)]}` → explicit errors
|
||||
|
||||
## Current blockers
|
||||
1. `sci.impl.copy-vars` not yet loaded — needed for `copy-core-var`, `copy-var`, `macrofy`, `new-var`
|
||||
2. `sci.impl.resolve`, `sci.impl.cljs`, `sci.impl.multimethods`, `sci.impl.deftype` not yet loaded
|
||||
3. Multi-arity function dispatch edge cases in utils (forms 36-37, 44-45)
|
||||
4. ~9 remaining eval failures across namespaces (5) and sci.core (4) — all tracing back to missing deps
|
||||
|
||||
## Key patterns
|
||||
|
||||
### Symbol structs
|
||||
```janet
|
||||
{:jolt/type :symbol :ns <string-or-nil> :name <string>}
|
||||
```
|
||||
|
||||
### Macro intern marks var
|
||||
```janet
|
||||
(def v (ns-intern ns name macro-fn))
|
||||
(put v :macro true)
|
||||
```
|
||||
|
||||
### Reader conditional `#?`
|
||||
Resolves at read time: scans for `:clj` keyword, picks next form.
|
||||
`#?@` wraps resolved form in `:jolt/splice` struct for list/vec/set splicing.
|
||||
Nil results (e.g. `#?(:cljs X)` on CLJ) now return `{:jolt/type :jolt/skip}` for non-splicing
|
||||
and `{:jolt/type :jolt/splice :items @[]}` for splicing — preventing orphaned keys in maps.
|
||||
|
||||
### Callable forms check
|
||||
```janet
|
||||
(if (function? f)
|
||||
(apply f args)
|
||||
(get f (first args))) ; table/struct lookup
|
||||
```
|
||||
|
||||
### unwrap-meta-name helper
|
||||
Recursively unwraps `(with-meta sym meta)` to extract the underlying symbol.
|
||||
Used in `def`, `ns`, `deftype`, `defmethod` to handle metadata-wrapped names.
|
||||
|
||||
### deftype →TypeName constructor
|
||||
`deftype` interns both `TypeName` and `->TypeName` (Clojure arrow constructor convention).
|
||||
|
||||
### bind-put helper and :jolt/nil sentinel
|
||||
Janet's `(put table key nil)` silently drops the key, even on mutable `@{}` tables.
|
||||
`bind-put` stores nil as `:jolt/nil` sentinel; `resolve-sym` unwraps `:jolt/nil` back to `nil`.
|
||||
Must be used for ALL binding `put` calls: `fn*`, `let*`, `loop*`, macro bodies, `deftype` reify.
|
||||
|
||||
### resolve-sym sentinels
|
||||
- `:jolt/not-found` — returned when a symbol is truly absent (distinct from nil binding)
|
||||
- `:jolt/nil` → unwrapped to actual `nil` — nil values in bindings stored as sentinel due to Janet `put` nil-drop
|
||||
- Auto-refer fallback: unqualified symbols not found in current ns fall back to `clojure.core`
|
||||
|
||||
## Pitfalls
|
||||
- Janet `let` can't bind to nil; use `(var x nil)` then `(set x val)`
|
||||
- Janet `(put table key nil)` silently drops the key — use `bind-put` helper for all binding tables
|
||||
- `(get table)` with 1 arg = compile error, use `(table :key)` shorthand
|
||||
- `(put fn :key val)` fails on functions; stash metadata on vars instead
|
||||
- `deftype` field names must be keywords (not strings) for `(inst :field)` access
|
||||
- `defn` placed after `core-bindings` that reference it → compile error; order matters
|
||||
- Janet's `try` macro: `(try body ([err] handler))` — catch clause is tuple `[binding body...]`
|
||||
- **`core-macro-names`** is a zero-arg fn returning a table: `(get (core-macro-names) name)`. Don't call it as `(core-macro-names name)` — that's arity mismatch
|
||||
- **Janet `#{}` sets** can cause parse issues — use `@[]` instead for stub collections
|
||||
- **`break` in `while`** doesn't return a value in Janet — use `(var done nil)` + `(while (and cond (not done)) ... (set done result))` pattern instead
|
||||
- **`(last string)` returns nil** — `last` works only on indexed types. Use `(s (- (length s) 1))` for last char of string
|
||||
- **`(set [a b] tuple)` doesn't work** — Janet's `set` doesn't support destructuring. Use `(tuple 0)` / `(tuple 1)`
|
||||
- **`#_` discard** works in lists, vectors, sets, and maps — wraps skipped form in `{:jolt/type :jolt/skip}` and readers check for this
|
||||
- **Map reader** must handle `:jolt/skip` and `:jolt/splice` in both key and value positions
|
||||
- **`comment` macro** must be registered in `core-macro-names` to avoid evaluating its body

# jolt-compiler
|
||||
|
||||
Jolt Compiler — Clojure→Janet source compiler with data-structure emission path.
|
||||
|
||||
## Architecture
|
||||
|
||||
```
|
||||
Clojure form → analyze-form [form bindings ctx] → AST {:op ...}
|
||||
↓ (if head = macro var)
|
||||
expand → re-analyze expanded form
|
||||
↓
|
||||
emit-ast (source string) or emit-expr (data structure)
|
||||
```
|
||||
|
||||
Three public entry points:
|
||||
- `(compile-form form &opt ctx)` → Janet source string (debug/display)
|
||||
- `(compile-ast form &opt ctx)` → Janet data structure (for eval)
|
||||
- `(compile-and-eval form ctx)` → compile-ast + eval
|
||||
|
||||
## Why data structures, not source strings
|
||||
|
||||
Janet's `eval` does NOT have access to `use`-imported symbols from the calling file. `(eval "(core-inc 1)")` fails with "unknown symbol core-inc". The fix: emit Janet tuples where function VALUES are embedded: `[core-inc 1]`.
|
||||
|
||||
```
|
||||
core-fn-values table: "core-inc" → core-inc (the actual function)
|
||||
emit-core-symbol-expr → (get core-fn-values janet-name)
|
||||
```
|
||||
|
||||
Source-to-source (`compile-form` + `emit-ast`) still exists for debugging but is NOT used by `compile-and-eval`.
|
||||
|
||||
## Symbol classification (in analyze-form)
|
||||
|
||||
Order: qualified ns → local binding → core-symbol → bare symbol
|
||||
|
||||
```
|
||||
(if (form :ns) → :qualified-symbol
|
||||
(get bindings name) → :local
|
||||
(get core-renames name) → :core-symbol
|
||||
→ :symbol)
|
||||
```
|
||||
|
||||
## core-renames vs core-fn-values
|
||||
|
||||
core-renames maps Clojure name strings → Janet function name strings (used by both emitter paths).
|
||||
core-fn-values maps Janet function name strings → actual function values (used by data-structure emitter only).
|
||||
|
||||
MUST keep both in sync. When adding a new core fn, update BOTH tables.
|
||||
**Missing entries → symbol treated as unknown global, returns nil.**
|
||||
|
||||
Key name mappings:
|
||||
- `"-"` → `"core-sub"` (NOT `"core--"`)
|
||||
- `"apply"` → `apply` (Janet built-in)
|
||||
- `"some"` → `core-some?` (shared with `core-some?`)
|
||||
- `"pr-str"` → `core-str` (alias)
|
||||
- `"list"` → `core-list`, `"name"` → `core-name`, `"subs"` → `core-subs`
|
||||
|
||||
## Loop/recur compilation
|
||||
|
||||
`loop*` emits a self-referential closure:
|
||||
```janet
|
||||
(do (var _loop_N nil)
|
||||
(set _loop_N (fn [params] body))
|
||||
(_loop_N init-vals...))
|
||||
```
|
||||
|
||||
`recur` saves `:loop-name` in the AST (looked up from bindings `:jolt/current-loop`), then `emit-recur-expr` rewrites to `(loop-name arg1 arg2...)`.
|
||||
|
||||
## Throw/try compilation
|
||||
|
||||
- `throw` → `(error val)` in Janet
|
||||
- `try/catch` → `(try body ([err] handler-body))` — Janet uses `([sym] handler)` format, NOT `(catch sym handler)`
|
||||
|
||||
## emit-vector-expr critical fix
|
||||
|
||||
**Bare tuples in Janet eval are function calls**: `[1 2 3]` tries to call `1` as a function. Always emit `['tuple ...]` or `(tuple ...)`.
|
||||
|
||||
## Quote in data-structure emitter
|
||||
|
||||
Use `raw-form->janet` to pass Jolt reader forms through verbatim to Janet's `quote`:
|
||||
```
|
||||
(emit-quote-expr expr) → ['quote (raw-form->janet expr)]
|
||||
```
|
||||
raw-form->janet converts Jolt symbols to Janet symbols, recursively for arrays/tuples.
|
||||
|
||||
## make-symbol fix (reader.janet)
|
||||
|
||||
`/` at position 0 means unqualified symbol. Use `(if (and slash (> slash 0)) ...)` — only split on `/` when it's not at the start.
|
||||
|
||||
## :data-readers key construction
|
||||
|
||||
`:data-readers` uses dynamic table construction because `:#inst` is invalid Janet keyword literal syntax (`:#` triggers reader macro):
|
||||
```janet
|
||||
:data-readers (let [dr @{}]
|
||||
(put dr (keyword "#inst") (fn [s] s))
|
||||
(put dr (keyword "#uuid") (fn [s] s))
|
||||
dr)
|
||||
```
|
||||
|
||||
## eval-string dispatch (compile mode)
|
||||
|
||||
```janet
|
||||
(if (or (= head-name "defmacro") (= head-name "ns")
|
||||
(= head-name "deftype") (= head-name "defmulti") (= head-name "defmethod")
|
||||
(= head-name "require") (= head-name "in-ns"))
|
||||
(eval-form ctx @{} form) ; interpret
|
||||
(compile-and-eval form ctx)) ; compile
|
||||
```
|
||||
|
||||
## Protocol dispatch macros
|
||||
|
||||
`core-extend-type` and `core-extend-protocol` emit `register-method` call forms. The fn* form MUST be `@[...]` (array) for `eval-list` to recognize it as a special form. Same for the outer call form wrapping `register-method`:
|
||||
|
||||
```janet
|
||||
(defn core-extend-type [type-sym proto-sym & impls]
|
||||
(each method-spec impls
|
||||
(def fn-form @[{:name "fn*"} arg-vec ;body]) ; @[...] array
|
||||
(array/push result @[
|
||||
{:name "register-method"} ; @[...] array
|
||||
type-sym proto-sym method-name fn-form])))
|
||||
```
|
||||
|
||||
## defprotocol method dispatch
|
||||
|
||||
Protocol methods emit fn forms that delegate to `protocol-dispatch` special form. The fn form uses `@[...]` for fn* and its body so eval-list dispatches correctly:
|
||||
|
||||
```janet
|
||||
(def fn-form @[
|
||||
{:name "fn*"}
|
||||
@[{:name "this"} {:name "&"} {:name "rest-args"}]
|
||||
@[{:name "protocol-dispatch"}
|
||||
{:name "quote"} protocol-name
|
||||
{:name "quote"} method-name
|
||||
{:name "this"}
|
||||
{:name "rest-args"}]])
|
||||
```
|
||||
|
||||
In register-method, args (type-sym, proto-sym, method-name) are passed raw — evaluator resolves via `(in form N)`.
|
||||
|
||||
## PHM integration in core functions
|
||||
|
||||
~16 core functions have PHM-aware branches before generic struct/table handling:
|
||||
`core-get`, `core-assoc`, `core-dissoc`, `core-conj`, `core-contains?`, `core-count`, `core-keys`, `core-vals`, `core-merge`, `core-merge-with`, `core-empty?`, `core-seq`, `core-into`, `core-map?`, `core-=`, `core-hash-map`. Sets later added to 6 of these.
|
||||
|
||||
## Test files
|
||||
|
||||
- `test/compiler-test.janet` — Phases 0-4 tests (source output + compile-eval + macro tests)
|
||||
- `test/phase6-final.janet` — Phase 6 comprehensive compile-mode tests (47 assertions)
|
||||
- `test/phase5-test.janet` — Phase 5 multimethod + hierarchy tests
|
||||
- `test/phase6-test.janet` — Phase 6 reader extension tests
|
||||
- `test/phase8-test.janet` — Phase 8 protocol system tests
|
||||
- `test/hash-map-test.janet` — Phase 2 PersistentHashMap tests
|
||||
|
||||
Run: `janet test/<file>.janet` or `jpm test`

Jolt development workflow — build, test, special form patterns, Janet gotchas
|
||||
|
||||
# Jolt Development
|
||||
|
||||
## Build & Test
|
||||
|
||||
```bash
|
||||
cd /Users/yogthos/src/jolt
|
||||
jpm build # produces build/jolt
|
||||
jpm test # runs all tests
|
||||
janet test/foo.janet # run a single test file from project root
|
||||
```
|
||||
|
||||
## Testing Patterns
|
||||
|
||||
```bash
|
||||
# Single test file
|
||||
janet test/compiler-test.janet
|
||||
|
||||
# Full suite
|
||||
jpm test
|
||||
|
||||
# Phase-specific tests
|
||||
janet test/phase5-test.janet # multimethods
|
||||
janet test/phase8-test.janet # protocol system
|
||||
janet test/phase10-test.janet # standard library
|
||||
|
||||
# REPL test — pipe expressions in
|
||||
printf "(range 10)\n[1 2 3]\n{:a 1}\n" | janet src/jolt/main.janet
|
||||
```
|
||||
|
||||
## Test File Creation — Heredoc Workaround
|
||||
|
||||
The `write` tool's syntax checker rejects `.janet` files with complex string escaping (e.g., `\"` inside Janet strings). **Workaround:** Use `bash` with `cat > file << 'EOF' ... EOF` heredocs for any test file containing Clojure source strings.
|
||||
|
||||
**Paren-counting boundary:** Large single-file test suites (>6 sections) often hit a mysterious paren-counting parse error ("unexpected end of source") at section boundaries, even when parens are balanced. **Workaround:** Split into multiple files (e.g., `cljs-port-1a.janet`, `cljs-port-1b.janet`).
|
||||
|
||||
## Loading .clj Files
|
||||
|
||||
`.clj` files are loaded via `eval-form` in the interpreter:
|
||||
```janet
|
||||
(def src (slurp "src/jolt/clojure/string.clj"))
|
||||
(var remaining src)
|
||||
(while (> (length (string/trim remaining)) 0)
|
||||
(def [form rest] (parse-next remaining))
|
||||
(set remaining rest)
|
||||
(when form (eval-form ctx @{} form)))
|
||||
```
|
||||
|
||||
**Critical constraint:** .clj files must NOT have docstrings on defn forms. Jolt's defn macro only handles 4-element forms: `(defn name [params] body)`. A 5-element form `(defn name "doc" [params] body)` causes "macro arity mismatch".
|
||||
|
||||
To add a new special form to the evaluator:
|
||||
|
||||
1. Add the name to `special-symbol?` in `src/jolt/evaluator.janet`
|
||||
2. Add a match arm in `eval-list` (the match on `name`)
|
||||
3. Add tests
|
||||
|
||||
The match arm receives `ctx`, `bindings`, and `form` (the full list). Use `(in form 1)` for first arg, etc.
|
||||
|
||||
**Non-symbol heads** (keywords, etc.): `eval-list` first checks `(and (struct? first-form) (= :symbol (...)))` before extracting `name`. If not a symbol, falls through to default function application.
|
||||
|
||||
### Current special forms (37):
|
||||
`quote`, `syntax-quote`, `unquote`, `unquote-splicing`, `do`, `if`, `def`, `defmacro`, `fn*`, `let*`, `loop*`, `recur`, `throw`, `try`, `set!`, `var`, `locking`, `instance?`, `defmulti`, `defmethod`, `deftype`, `new`, `.`, `var-get`, `var-set`, `var?`, `alter-var-root`, `find-var`, `intern`, `alter-meta!`, `reset-meta!`, `disj`, `set?`, `satisfies?`, `protocol-dispatch`, `register-method`, `make-reified`
|
||||
|
||||
## Compiler Architecture
|
||||
|
||||
Two-phase: `analyze-form [form bindings ctx]` → `emit-ast` (string) or `emit-expr` (data structures).
|
||||
|
||||
**Why data structures:** Janet's `eval` can't see `use`-imported symbols. Embed function VALUES directly via `core-fn-values` table.
|
||||
|
||||
**eval-string dispatch** (compile mode): stateful forms → interpreter; everything else → `compile-and-eval`. Macros expand at analyze time.
|
||||
|
||||
## Protocol System
|
||||
|
||||
Protocols are maps with `:jolt/type :jolt/protocol` and `:methods` map.
|
||||
Type registry in context env (`:type-registry`) maps `type-tag → proto-name → method-name → fn`.
|
||||
|
||||
**Special forms:**
|
||||
- `protocol-dispatch [proto-sym method-sym obj rest-args]` — resolves method via type registry or reified methods
|
||||
- `register-method [type-sym proto-sym method-sym fn-form]` — stores impl in type registry
|
||||
- `make-reified [proto-sym methods-map]` — creates anonymous object with `:jolt/protocol-methods`
|
||||
|
||||
**Critical rule:** fn* form inside extend-type/extend-protocol MUST be `@[...]` (array) to trigger eval-list's special form dispatch. Tuples `[...]` hit `(tuple? form)` branch instead. Same for register-method, protocol-dispatch calls.
|
||||
|
||||
## REPL Collection Rendering (Buffer-Based)
|
||||
|
||||
Use `write-value` + `write-collection` with a StringBuffer (`@""`) rather than `prin`/`print` directly. Build the entire output string in a buffer, then atomically `(print (string buf))`. Prevents Janet's C runtime (in `jpm build` executables) from interleaving its native `<tuple 0x...>` printer between incremental `prin` calls.
|
||||
|
||||
```janet
|
||||
(var write-value nil) ; forward declaration
|
||||
|
||||
(defn- write-collection [v buf]
|
||||
(cond (tuple? v) (do (buffer/push-string buf "[") ...)
|
||||
(array? v) (do (buffer/push-string buf "(") ...) ...))
|
||||
|
||||
(set write-value (fn [v buf]
|
||||
(cond (nil? v) (buffer/push-string buf "nil")
|
||||
(number? v) (buffer/push-string buf (string v))
|
||||
(tuple? v) (write-collection v buf)
|
||||
true (buffer/push-string buf (string v))))) ; true REQUIRED
|
||||
|
||||
(defn print-value [v] (def buf @"") (write-value v buf) (print (string buf)))
|
||||
```
|
||||
|
||||
**Critical:** Janet's `cond` treats a bare expression in the last position as a **test** clause, not a catch-all body. Use `true` as the guard.
|
||||
|
||||
## PersistentHashMap Gotchas
|
||||
|
||||
- `core-map?`: `(if (and (table? x) (get x :jolt/deftype)) true false)` — `and` returns last truthy, not boolean
|
||||
- `core-count`: subtract 1 for deftype tables (skip `:jolt/deftype` key)
|
||||
- Equality: convert via `phm-to-struct` before `deep=`
|
||||
|
||||
## defrecord / deftype Patterns
|
||||
|
||||
- defrecord emits `(deftype TypeName [fields])` + arrow factory
|
||||
- Records are tables with `:jolt/deftype` = type name string
|
||||
- `set!` field mutation: `(set! (.-x obj) val)` parses as array with `.-x` symbol head
|
||||
|
||||
## Binding Macro
|
||||
|
||||
Uses `array-map` (plain Janet struct) not `hash-map` (PHM) to avoid PHM get() incompatibility with `var-get`.
|
||||
|
||||
## Tagged Literals (#inst, #uuid)
|
||||
|
||||
Use dynamic table construction: `(let [dr @{}] (put dr (keyword "#inst") fn) dr)`
|
||||
|
||||
## LazySeq Patterns
|
||||
|
||||
- Use `indexed?` not `tuple?` for realized sequences (may be arrays from `cons`/`concat`)
|
||||
- Avoid `val'` (apostrophe in symbol names) — use `vf` instead
|
||||
|
||||
|
||||
|
||||
- `def` creates constants; use `(var x nil)` for mutable locals
|
||||
- Bare tuples in `eval` are function calls: `[1 2 3]` tries to call `1`
|
||||
- `try` format: `(try body ([err] handler))` NOT `(try body (catch sym handler))`
|
||||
- core-renames MUST match actual fn names: `"-"` → `"core-sub"` (not `"core--"`)
|
||||
- `(break val)` breaks from loop returning val — useful in bucket search patterns
|
||||
- `boolean` doesn't exist — use `(if x true false)`
|
||||
- Janet doesn't support Clojure-style multi-arity defn — use `[& args]` with `case (length args)`
|
||||
- Janet's `cond` treats bare expression in last position as test, not catch-all — use `true` guard

description: Common pitfalls and workarounds discovered during Jolt implementation

|

|
||||
# jolt-gotchas
|
||||
|
||||
Recurring pitfalls and their fixes discovered across all implementation phases.
|
||||
|
||||
## PHM/Set Metadata Key Leakage
|
||||
|
||||
PHM and set internal keys (`:jolt/deftype`, `:cnt`, `:buckets`, `:_meta`, `:jolt/type`, `:phm`) leak into `pairs`/`keys` iteration. Must filter in merge, merge-with, keys, vals, and print-collection.
|
||||
|
||||
```janet
|
||||
(when (and (not= k :jolt/deftype) (not= k :cnt)
|
||||
(not= k :buckets) (not= k :_meta)
|
||||
(not= k :jolt/type) (not= k :phm)) ...)
|
||||
```
|
||||
|
||||
## Keywords with `#` Are Invalid Janet Literals
|
||||
|
||||
`:#inst`, `:#uuid` cause parse errors. Use dynamic table construction:
|
||||
```janet
|
||||
(let [dr @{}] (put dr (keyword "#inst") fn) dr)
|
||||
```
|
||||
|
||||
## Janet `break` Only Works in Loops
|
||||
|
||||
Does NOT work inside `let`. Use `(var found nil)` + `(set found val) (break)` pattern.
|
||||
|
||||
## Bare Tuples in `eval` Are Function Calls
|
||||
|
||||
`(eval [1 2 3])` calls `1` as function. Use `['tuple 1 2 3]` in data-structure emitter.
|
||||
|
||||
## Janet `case` for Multi-Arity
|
||||
|
||||
Janet lacks Clojure-style multi-arity defn. Use `(defn f [& args] (case (length args) 1 ... 2 ...))`.
|
||||
|
||||
## core-renames + core-fn-values Must Stay in Sync
|
||||
|
||||
Both tables must be updated together when adding core fns. Missing entries = silent nil returns. `"-"` is `core-sub` NOT `core--`.
|
||||
|
||||
## `set!` Field Mutation Reader Quirk
|
||||
|
||||
`(set! (.-x obj) val)` parses as array with `.-x` symbol head — not as standalone `.-x` symbol. Check for this case before the `(. obj -field)` shorthand.
|
||||
|
||||
## Janet `cond` Requires `true` Guard for Catch-All
|
||||
|
||||
A bare expression in the last position of `cond` is treated as a **test** clause (not body). Use `true` as the test:
|
||||
|
||||
```janet
|
||||
(cond (nil? x) (buf "nil") (number? x) (buf (string x)) true (buf (string x)))
|
||||
```
|
||||
|
||||
Without `true`, the last expression executes as a side-effect test between branches. Hit us in buffer-based write-value — raw tuple addresses leaked into REPL output.
|
||||
|
||||
## REPL: Buffer-Based Output Prevents C-Runtime Interleaving
|
||||
|
||||
Janet's C runtime in `jpm build` executables interleaves native `<tuple 0x...>` output between `prin` statements. Solution: build entire output string in a buffer, then output atomically with a single `print` call. Use `write-value/v buf` + `print-value` creates buffer → `print (string buf)`.
|
||||
|
||||
## Janet `struct?` Returns `true` for Tuples
|
||||
|
||||
Always check `(tuple? x)` BEFORE `(struct? x)` in cond forms. Otherwise `(get tuple :key)` fails with "expected integer key for tuple in range [0, N), got :key". Hit us in `print-value` (symbol check on tuples) and `eval-form` struct handling.
|
||||
|
||||
## PHM Internal Key Leakage
|
||||
|
||||
PHM and set internal keys (`:jolt/deftype`, `:cnt`, `:buckets`, `:_meta`, `:jolt/type`, `:phm`) leak into `pairs`/`keys` iteration. Core fns that iterate collections (`core-merge`, `core-reduce`, `core-every?`, `core-filter`) must check for `set?`/`phm?` first and use type-aware helpers (`phm-to-struct`, `phs-seq`, `phm-keys`, `phm-entries`) before generic iteration.

# jolt-persistent-structures
|
||||
|
||||
PersistentHashMap, PersistentHashSet, and LazySeq implementation patterns in Janet tables.
|
||||
|
||||
## PersistentHashMap
|
||||
|
||||
Bucket-based immutable hash map using copy-on-write. Stores data in `:buckets` (array of flat `[k v k v ...]` bucket arrays), `:cnt` (entry count), `:jolt/deftype` type tag, and `:_meta`.
|
||||
|
||||
### Core functions (in phm.janet)
|
||||
- `make-phm [& kvs]` — create from key-value pairs
|
||||
- `phm-get [m k &opt default]` — lookup with optional default
|
||||
- `phm-assoc [m k v]` — return new map with k→v
|
||||
- `phm-dissoc [m k]` — return new map without k
|
||||
- `phm-contains? [m k]` — membership check
|
||||
- `phm-count [m]` — number of entries
|
||||
- `phm-to-struct [m]` — convert to Janet struct (for equality, keys, vals)
|
||||
- `phm-entries [m]` — return `[[k v] ...]` pairs
|
||||
|
||||
### Core function integration (core.janet)
|
||||
Each core fn checks `phm?` first, then falls through to struct/table logic:
|
||||
- `core-get` → `phm-get`
|
||||
- `core-assoc` → `phm-assoc`
|
||||
- `core-dissoc` → `phm-dissoc`
|
||||
- `core-contains?` → `phm-contains?`
|
||||
- `core-count` → `phm-count`
|
||||
- `core-keys/vals/seq` → via `phm-to-struct`
|
||||
- `core-merge/merge-with` → PHM-aware iteration
|
||||
- `core-empty?` → check `:cnt = 0`
|
||||
- `core-conj` → `phm-assoc` for `[k v]` pairs
|
||||
|
||||
### Gotchas
|
||||
- `core-map?`: `(if (and (table? x) (get x :jolt/deftype)) true false)` — `and` returns last truthy
|
||||
- `core-count`: subtract 1 for deftype tables
|
||||
- Equality: `phm-to-struct` → `deep=`
|
||||
- `core-hash-map` wraps `make-phm`, so all literal maps become PHMs
|
||||
|
||||
## PersistentHashSet
|
||||
|
||||
Backed by a PersistentHashMap with sentinel `true` values.
|
||||
|
||||
### Core functions (in phm.janet)
|
||||
- `make-phs [& xs]` — create from items
|
||||
- `phs-conj [s & xs]` — add items (idempotent)
|
||||
- `phs-disj [s & xs]` — remove items
|
||||
- `phs-contains? [s x]` — membership
|
||||
- `phs-count [s]` — cardinality
|
||||
- `phs-seq [s]` — keys as tuple
|
||||
- `phs-get [s x &opt default]` — returns x if present
|
||||
- `phs-to-struct [s]` — convert for equality via `deep=`
|
||||
|
||||
### Special forms (evaluator.janet)
|
||||
- `:jolt/set` handler: `(apply make-phs (form :value))`
|
||||
- `"disj"` dispatch — validates set?, calls `phs-disj`
|
||||
- `"set?"` dispatch — calls `set?` predicate
|
||||
|
||||
## LazySeq
|
||||
|
||||
Realize-once thunk wrapper.
|
||||
|
||||
### Core functions (in phm.janet)
|
||||
- `make-lazy-seq [thunk]` — create from thunk
|
||||
- `realize-ls [ls]` — force + cache (recursive)
|
||||
- `ls-first/ls-rest/ls-seq/ls-count`
|
||||
|
||||
### Gotchas
|
||||
- Use `indexed?` not `tuple?` for realized sequences
|
||||
- Avoid `val'` (parse error), use `vf`

# JPM Build & Debug
|
||||
|
||||
## Build Commands
|
||||
|
||||
```bash
|
||||
jpm build # Compile and link executable → build/jolt
|
||||
jpm test # Run all tests
|
||||
jpm deps # Show dependencies
|

```
|
||||

## project.janet Structure
|
||||
|
||||
```janet
|
||||
(declare-project
|
||||
:name "jolt"
|
||||
:description "...")
|
||||
|
||||
(declare-source
|
||||
:source @["src"]) # Source directories
|
||||
|
||||
(declare-executable
|
||||
:name "jolt" # Output binary name
|
||||
:entry "src/jolt/main.janet") # RELATIVE TO PROJECT ROOT, not source dirs
|
||||
```
|
||||
|
||||
## Common Pitfalls
|
||||
|
||||
### Entry path is relative to project root
|
||||
Even though `declare-source` lists `@["src"]`, the `:entry` in `declare-executable` must include `src/` prefix. jpm's `create-executable` calls `dofile source` with the raw entry string.
|
||||
|
||||
### main function required for native compilation
|
||||
`create-executable` extracts a `main` function from the entry file's environment. Top-level code runs during `dofile` and interferes with image generation. Error: "expected integer key for keyword in range [0, 5), got nil".
|
||||
|
||||
**Fix:** Wrap startup code in `(defn main [&] ...)`.
|
||||
|
||||
```janet
|
||||
(defn main [&]
|
||||
(print "REPL started")
|
||||
;; ... REPL loop ...
|
||||
)
|
||||
```
|
||||
|
||||
### LSP false positives
|
||||
Clojure LSP misidentifies `.janet` files. Ignore all diagnostics — they don't affect build or test results.
|
||||
|
||||
## Debugging Build Failures
|
||||
|
||||
1. Check entry path includes `src/` prefix
|
||||
2. Check entry file has `(defn main [&] ...)` wrapping top-level code
|
||||
3. Run `jpm test` to verify code works before native compilation
|
||||
4. `jpm build` produces no output on success — check exit code only

`(init)` returns a context with `clojure.core` loaded. Pass it to `eval-string` to evaluate Clojure source. Each context is isolated — use separate contexts for separate evaluation environments.
|
||||
|
||||
## Janet-native interop
|
||||
|
||||
Jolt provides CLJS-style host interop through the `.` special form on any Janet table or struct:
|
||||
|
||||
```clojure
|
||||
;; Field access on tables and structs
|
||||
user=> (def t {:a 1 :b 2})
|
||||
user=> (. t :a) ;; → 1
|
||||
user=> (.-a t) ;; → 1 (reader sugar)
|
||||
|
||||
;; Method calls — self is passed as first arg
|
||||
user=> (def obj {:greet (fn [self name] (str "Hello " name))})
|
||||
user=> (. obj greet "Alice") ;; → "Hello Alice"
|
||||
|
||||
;; Multi-arg methods
|
||||
user=> (def calc {:add (fn [_ a b] (+ a b))})
|
||||
user=> (. calc add 3 4) ;; → 7
|
||||
```
|
||||
|
||||
Any table or struct field that holds a Janet function or C function can be called via `.` with implicit `self` dispatch. This pattern mirrors CLJS `.method` call semantics and unifies deftype protocol dispatch with plain Janet host interop.
|
||||
|
||||
**Janet host functions** — Janet's standard library (`os/shell`, `net/request`, etc.) is accessible through Jolt's `jolt.interop` namespace:
|
||||
|
||||
```clojure
|
||||
user=> (require '[jolt.interop :as j])
|
||||
user=> (j/janet-eval "(+ 1 2)") ;; → 3
|
||||
user=> (j/janet-table-keys {:a 1 :b 2}) ;; → [:a :b]
|
||||
user=> (j/janet-describe "hello") ;; → Janet type info
|
||||
```
|
||||
|
||||
The existing `jolt.shell`, `jolt.http`, and `jolt.interop` modules demonstrate the pattern: Clojure functions call Janet C functions through the Jolt bridge.
