moe-charm b8bdb867d8 Merge selfhosting-dev into main (Core-13 pure CI/tests + LLVM bridge) (#126)
* WIP: sync before merging origin/main

* fix: unify using/module + build CLI; add missing helper in runner; build passes; core smokes green; jit any.len string now returns 3

* Apply local changes after merging main; keep docs/phase-15 removed per main; add phase-15.1 docs and tests

* Remove legacy docs/phase-15/README.md to align with main

* integration: add Core-13 pure CI, tests, and minimal LLVM execute bridge (no docs) (#125)

Repository Guidelines

Project Structure & Module Organization

  • src/: Nyash core (MIR, backends, runner modes). Key: backend/, runner/, mir/.
  • crates/nyrt/: NyRT static runtime for AOT/LLVM (libnyrt.a).
  • plugins/: Firstparty plugins (e.g., nyash-array-plugin).
  • apps/ and examples/: Small runnable samples and smokes.
  • tools/: Helper scripts (build, smoke).
  • tests/: Rust and Nyash tests; historical samples in tests/archive/.
  • nyash.toml: Box type/plugin mapping used by runtime.

Build, Test, and Development Commands

  • Build (JIT/VM): cargo build --release --features cranelift-jit
  • Build (LLVM AOT): LLVM_SYS_180_PREFIX=$(llvm-config-18 --prefix) cargo build --release --features llvm
  • Quick VM run: ./target/release/nyash --backend vm apps/APP/main.nyash
  • Emit + link (LLVM): tools/build_llvm.sh apps/APP/main.nyash -o app
  • Smokes: ./tools/llvm_smoke.sh release (use env toggles like NYASH_LLVM_VINVOKE_RET_SMOKE=1)

JIT SelfHost Quickstart (Phase 15)

  • Core build (JIT): cargo build --release --features cranelift-jit
  • Core smokes (plugins disabled): NYASH_CLI_VERBOSE=1 ./tools/jit_smoke.sh
  • Roundtrip (parser pipe + json): ./tools/ny_roundtrip_smoke.sh
  • Plugins smoke (optional gate): NYASH_SKIP_TOML_ENV=1 ./tools/smoke_plugins.sh
  • Using/Resolver E2E sample (optional): ./tools/using_e2e_smoke.sh (requires --enable-using)
  • Bootstrap c0→c1→c1' (optional gate): ./tools/bootstrap_selfhost_smoke.sh

Flags

  • NYASH_DISABLE_PLUGINS=1: Core経路安定化CI常時/デフォルト)
  • NYASH_LOAD_NY_PLUGINS=1: nyash.tomlny_plugins を読み込むstd Ny実装を有効化
  • --enable-using or NYASH_ENABLE_USING=1: using/namespace を有効化
  • NYASH_SKIP_TOML_ENV=1: nyash.toml の [env] 反映を抑止(任意ジョブの分離に)
  • NYASH_PLUGINS_STRICT=1: プラグインsmokeでCore13厳格をONにする
  • NYASH_USE_NY_COMPILER=1: NyコンパイラMVP経路を有効化Rust parserがフォールバック

Phase 15 PolicySelfHosting 集中ガイド)

  • フォーカス: Ny→MIR→VM/JITJITはcompileronly/独立実行)での自己ホスト実用化。
  • スコープ外DoNotDo: AOT/リンク最適化、GUI/egui拡張、過剰な機能追加、広域リファクタ、最適化の深追い、新規依存追加。
  • ガードレール:
    • 小刻み: 作業は半日粒度。詰まったら撤退→Issue化→次タスクにスイッチ。
    • 検証: 代表スモークRoundtrip/using/modules/JIT直/collectionsを常時維持。VMとJIT(--jit-direct)の一致が受け入れ基準。
    • 観測: hostcall イベントは 1 呼び出し=1 件、短絡は分岐採用の記録のみ。ノイズ増は回避。
  • 3日スタートプラン:
    1. JSON v0 短絡 &&/|| を JSON→MIR→VM→JIT の順で最小実装。短絡副作用なしを smoke で確認。
    2. collections 最小 hostcalllen/get/set/push/size/hasと policy ガードの整合性チェック。
    3. 観測イベントobserve::lower_hostcall / lower_shortcircuitを整備し、代表ケースで一貫した出力を確認。

Coding Style & Naming Conventions

  • Rust style (rustfmt defaults): 4space indent, snake_case for functions/vars, CamelCase for types.
  • Keep patches focused; align with existing modules and file layout.
  • New public APIs: document minimal usage and expected ABI (if exposed to NyRT/plugins).

Testing Guidelines

  • Rust tests: cargo test (add targeted unit tests near code).
  • Smoke scripts validate endtoend AOT/JIT (tools/llvm_smoke.sh).
  • Test naming: prefer *_test.rs for Rust and descriptive .nyash files under apps/ or tests/.
  • For LLVM tests, ensure LLVM 18 is installed and set LLVM_SYS_180_PREFIX.

Commit & Pull Request Guidelines

  • Commits: concise imperative subject; scope the change (e.g., "llvm: fix argc handling in nyrt").
  • PRs must include: description, rationale, reproduction (if bug), and run instructions.
  • Link issues (docs/issues/*.md) and reference affected scripts (e.g., tools/llvm_smoke.sh).
  • CI: ensure smokes pass; use env toggles in the workflow as needed.

Security & Configuration Tips

  • Do not commit secrets. Plugin paths and native libs are configured via nyash.toml.
  • LLVM builds require system LLVM 18; install via apt.llvm.org in CI.
  • Optional logs: enable NYASH_CLI_VERBOSE=1 for detailed emit diagnostics.

Codex Async Workflow (Background Jobs)

  • Purpose: run Codex tasks in the background and notify a tmux session on completion.
  • Script: tools/codex-async-notify.sh
  • Defaults: posts to tmux session codex (override with env CODEX_DEFAULT_SESSION or 2nd arg); logs to ~/.codex-async-work/logs/.

Usage

  • Quick run (sync output on terminal):
    • ./tools/codex-async-notify.sh "Your task here" [tmux_session]
  • Detached run (returns immediately):
    • CODEX_ASYNC_DETACH=1 ./tools/codex-async-notify.sh "Your task" codex
  • Tail lines in tmux notification (default 60):
    • CODEX_NOTIFY_TAIL=100 ./tools/codex-async-notify.sh "…" codex

Concurrency Control

  • Cap concurrent workers: set CODEX_MAX_CONCURRENT=<N> (0 or unset = unlimited).
  • Mode when cap reached: CODEX_CONCURRENCY_MODE=block|drop (default block).
  • Deduplicate same task string: CODEX_DEDUP=1 to skip if identical task is running.
  • Example (max 2, dedup, detached):
    • CODEX_MAX_CONCURRENT=2 CODEX_DEDUP=1 CODEX_ASYNC_DETACH=1 ./tools/codex-async-notify.sh "Refactor MIR 13" codex

Keep Two Running

  • Detect running Codex exec jobs precisely:
    • Default counts by PGID to treat a task with multiple processes (node/codex) as one: CODEX_COUNT_MODE=pgid
    • Raw process listing (debug): pgrep -af 'codex.*exec'
  • Top up to 2 jobs example:
    • COUNT=$(pgrep -af 'codex.*exec' | wc -l || true); NEEDED=$((2-${COUNT:-0})); for i in $(seq 1 $NEEDED); do CODEX_ASYNC_DETACH=1 ./tools/codex-async-notify.sh "<task $i>" codex; done

Notes

  • tmux notification uses paste-buffer to avoid broken lines; increase tail with CODEX_NOTIFY_TAIL if you need more context.
  • Avoid running concurrent tasks that edit the same file; partition by area to prevent conflicts.
  • If wrappers spawn multiple processes per task (node/codex), set CODEX_COUNT_MODE=pgid (default) to count unique process groups rather than raw processes.
