These fn params are used inside deeply nested closures (try/catch inside fn inside testing block). The IIFE wrapping by `emitBlock` creates scope boundaries that prevent fn params from being visible in inner closures. -- **Fix needed**: IIFE-wrapped closures must capture enclosing scope variables. Either stop wrapping non-last forms in IIFEs, or use Nim closures that properly capture outer variables. +### Previous failures resolved: -### 3. `remove_watch` — Same closure scoping issue -- **Error**: `undeclared identifier: 'ref1'` -- **Cause**: Same as `add_watch` — fn params not visible across IIFE boundaries. -- **Fix needed**: Same as `add_watch`. +### 1. `not_eq` — Cross-namespace dependency ✅ +- **Root cause**: `extractRequires` didn't find `ns` inside `(do ...)` wrapper from test runner. `resolveNsToPath` only tried `.clj` extension, not `.cljc`. Search path didn't include test suite directory. +- **Fix**: Made `extractRequires` recurse into `do` forms, added `.cljc` fallback in `resolveNsToPath`, added test suite auto-detection in search paths, filtered to only inline `def`/`defn` from required files (not macros). -## Roadmap to 100% +### 2. `add_watch` — STM ref functions missing ✅ +- **Root cause**: `(ref 10)` emitted as `ref1(cljInt(10))` instead of `cljRef(cljInt(10))`. `dosync`, `ref-set`, `alter` also missing. +- **Fix**: Added runtime name mappings (`ref`→`cljRef`, `ref-set`→`cljRefSet`, `dosync`→`cljDosync`, `alter`→`cljAlter`). Implemented minimal STM ref runtime functions. -### Phase A: Closure Scoping Fix (fixes add_watch + remove_watch) -- **Approach**: Instead of wrapping non-last forms in `discard ((proc(): CljVal = ...)())`, emit them as direct statements. The IIFE wrapping was added to handle multi-line expressions as non-last forms, but it breaks variable scoping. -- **Alternative**: Use Nim's `{.inline.}` procs or `block:` labels instead of IIFEs for scope isolation. -- **Impact**: +2 tests (232/233) +### 3. `remove_watch` — Same STM ref issue ✅ +- **Root cause**: Same as `add_watch` — uses `ref`, `dosync`, `alter`. +- **Fix**: Same as `add_watch`. -### Phase B: Multi-file Compilation (fixes not_eq) -- **Approach**: When `ns :require` encounters a namespace, find and compile the corresponding `.cljc`/`.clj` file, inline its top-level defs into the current compilation unit. -- **Key files**: `src/cljnim.nim` (file resolution), `src/emitter.nim` (ns handler) -- **Impact**: +1 test (233/233) +## Symbol Emit Fix (Phase C) — Deferred -### Phase C: Symbol Emit Fix (fixes 2 unit tests) -- **Approach**: When emitting a bare symbol that's not a local var and not a runtime function, check if it was defined as a `def`/`defn` in the current compilation unit. If so, emit the mangled name directly instead of `cljSymbol(...)`. -- **Impact**: +2 unit tests (80/80) +The 2 failing unit tests (`emit symbol`, `emit mangled symbol`) require a proper def registry to distinguish between code references (emit mangled name) and symbol values (emit `cljSymbol(...)`). A simpler fix (emitting all symbols as mangled names) breaks compliance tests that use symbol literals like ratio `22/7` which Nim can't parse as numbers. This requires more careful design and will be addressed later. ## Session Log +### 2026-05-11 (current session) — 233/233 (100%) +- Emitter: added `ref`, `ref-set`, `dosync`, `alter` runtime mappings + variadic lists +- Runtime: implemented `cljRef`, `cljRefSet`, `cljDosync`, `cljAlter` +- Reader: added special float token handling for `nan`/`inf`/`-inf` +- Compiler: `extractRequires` now walks `do` forms for `ns` extraction +- Compiler: `resolveNsToPath` tries `.cljc` fallback extension +- Compiler: auto-detects `/tmp/clojure-test-suite/test` as search path +- Compiler: filters required file inlining to only `def`/`defn`/`defn-` (excludes macros) +- Emitter: fixed `NaN`/`Inf` float constants (Nim's `$NaN` produces lowercase `nan`) +- Result: 230/233 → 233/233 compliance + ### 2026-05-11 (late session) — Bulk fixes -
