ZZ

+ +

Fast systems language: native AOT, green threads, zero GC pauses.

+ +

+ Website | + Getting started | + Learn | + Documentation | + Contributing +

+ +## Why ZZ? + +- Native binaries via `zz build`, fast iteration via `zz run`. +- Green threads and channels for concurrent pipelines. +- Inferred types, pipelines (`|>`), pattern matching. +- Diagnostics that suggest fixes, plus `zz fix` and `zz fmt`. +- Batteries included: HTTP, JSON, fs, math, SQL. + +## How is ZZ different from Rust? + +ZZ is not syntactic sugar on top of Rust. It is an independent language +with its own frontend, type checker, tree-walk VM, and AOT backend +(ZZ → C → native binary), plus its own standard library. + +- **Memory without a borrow checker.** ZZ has value semantics: functions + receive copies from the programmer's perspective, there are no + references, no lifetimes, no `&`/`&mut`. The compiler/runtime may elide + copies internally (copy-on-write, in-place slots), but aliasing is never + observable. Rust gives you control via ownership/borrows; ZZ trades that + control for simpler reasoning. +- **Concurrency model.** ZZ ships green threads and channels as the default + pipeline primitive. No `async`/executors to wire up for the common case. +- **Scope.** ZZ targets services, CLIs, and data pipelines with batteries + included (HTTP, JSON, fs, SQL). It cannot do everything Rust can: no + `unsafe`, no zero-cost abstractions, no `no_std`/embedded, no manual + layout control. For those, use Rust (including as a ZZ native plugin). +- **Interop.** ZZ plugins speak C ABI (`plugin.zzi`); Rust crates can back + plugins, but the ZZ side never exposes Rust semantics. + +## Quick start + +Install (main way, latest GitHub release). Re-run to update: ```bash -# Install -cargo install --path crates/zz_cli +curl -fsSL https://zz-lang.pages.dev/install.sh | sh +``` -# Run a file -zz run hello.zz +Windows: -# Start REPL -zz +```powershell +irm https://zz-lang.pages.dev/install.ps1 | iex +``` -# Check for errors -zz check src/ +Verify: + +```bash +zz --version +zz setup # PATH + shell completions for bash/zsh/fish (run once) ``` +Hello world (`hello.zz`): + ```zz -// hello.zz name := input("What is your name? ") println("Hello, {name}!") +``` -func factorial(n: int) -> int { - if n <= 1 { 1 } else { n * factorial(n - 1) } -} - -println("5! = {factorial(5)}") +```bash +zz run hello.zz ``` -## Features +REPL, check, format: -- **Inferred declarations** -- `x := 1` infers `int`; `x: float = 1.0` declares explicitly -- **Pipeline operator** -- `val |> func()` chains function calls, including across lines -- **Pattern matching** -- `match` with exhaustive variant patterns, `if let` for binding -- **Elvis operator** -- `val ?? fallback` unwraps or provides default -- **String interpolation** -- `"Hello {name}"` with format specs `{pi:.2f}` -- **Closures** -- `|x: int| x * 2` with captured environment -- **Generics** -- `func map(...)` with type inference -- **Standard library** -- HTTP, JSON, filesystem, math, string operations -- **LSP support** -- autocompletion, go-to-definition, hover, diagnostics, formatting -- **Smart diagnostics** -- Levenshtein suggestions, fix-it hints, source-mapped errors +```bash +zz # REPL (:help, :quit) +zz check src/ +zz fmt src/ +``` -## Architecture +Install a project as a tool (`~/.zz/bin`): -``` -zz_frontend Lexer, parser, AST, lossless formatter, diagnostics -zz_checker Unification-based type checker with inference -zz_runtime Tree-walker interpreter + bytecode VM -zz_stdlib Standard library (70+ native functions) -zz_cli CLI binary: REPL, run, check, fix, fmt -zz_lsp Language Server Protocol implementation +```bash +zz install --path . ``` -``` -zz_frontend ──> zz_checker ──> zz_stdlib ──> zz_cli - | | - v v - zz_runtime

Move-on-self-reassign analysis shared by all engines. +//! +//! ## Exact rule +//! +//! For a statement `x = RHS` (or `x := RHS`) where `x` is a plain local, +//! the single occurrence of `x` inside `RHS` may be *moved* (taken out of +//! its slot, leaving `Unit` behind until the final store) instead of +//! cloned when every clause below holds: +//! +//! 1. **Single occurrence.** `x` is referenced exactly once in the whole +//! `RHS` — as `x`, `x.y`, or `x[i]` (any reference counts). Two reads +//! (`x = x + x`, `x = f(x, x)`) need the value twice; no move. +//! 2. **No closures, no spawn in `RHS`.** A closure literal captures the +//! scope and could observe the transient `Unit` when invoked before the +//! store completes; `spawn` snapshots the scope (same hazard). +//! 3. **No other calls in the moved value's way — for `ThreadCall`.** +//! For `vec.push` shapes the element argument needs no purity: engines +//! evaluate it *before* the take, while the slot is still intact, so +//! even calls/closures/spawns there observe the old value and the +//! take→push→store window runs no user code at all. For `x = f(x, ...)` +//! the take comes first, so every argument other than `x` itself must +//! be call-free, closure-free and spawn-free; the callee itself is +//! vetted per engine (native: plain local + not captured; VM: runtime +//! scope-share check). +//! 4. **Loop iterators.** Sequential re-reads (conditions, bounds) are safe +//! by construction — the store completes before any re-read. The only +//! loop hazard is a *live borrow* of `x`'s buffer (native `for v in x` +//! holds `iter_tmp`, a cloned share): the refcount uniqueness check +//! (`refs == 1`) fails while borrowed and forces the copy fallback. +//! 5. **Field aliases.** Native container stores share (`refs` bump), so an +//! `x` aliased through a dict/array/struct field fails the uniqueness +//! check and falls back. VM stores deep-clone on read, so field aliases +//! cannot exist (closure scope-sharing is the only VM alias — clause 2 +//! plus the scope-share check cover it). +//! +//! ## Shapes +//! +//! - `VecPush(x)`: `x = vec.push(x, e)` / `x = std.vec.push(x, e)` / +//! `x = x.push(e)` (method spellings).

The code comment already flags "tracked as follow-up (see move_append_struct_copy known-failure)".

Check: does `zz_clone_for_store` handle `ZZ_ARRAY` with arena sentinel `refs==0`/`LIT_MAGIC`/`ARENA_MAGIC`?

Dump the failing C: `zz build --verbose` keeps the TU (see `crates/zz_cli/src/build.rs:966` `lower_only` + `emit_c_plus_script`); capture the `t.rows = …push…` + `rows[0][0]` region and attach to the fix PR. +5. Only then choose the fix below (A/B/C) — do not "fix" the minimal passing repro. + +### 2.4 Fix candidates (pick after Phase 0, in this order) + +- **A (most likely): heal/clone arrays on retaining stores.** Extend `zz_clone_for_store` (or add `zz_clone_array_for_store`) to dup arena/stack/lit arrays on store into escaping containers (`zz_vec_append/push`, `zz_dict_set`, `zz_object_set_field`, `zz_array_set`), mirroring the existing string-heal. Guard: only when `refs` is a sentinel (`0`, `STACK/LIT/ARENA_MAGIC`); heap `refs>=1` keeps sharing + bump. +- **B: tighten the `refs==1` in-place gate.** Make field-buffer sharing exact: either deep-bump field arrays on struct clone (costly — measure), or add COW on field write (check `slot->arr->refs` **and** object alias count), or disable `zz_object_push_field_take` in-place when the base object `refs > 1`. Smallest safe change: fall back to `get+push+set` whenever the base object is shared. +- **C: fix temp lifetime in chained `a[i][j]` / `t.f[i][j]` lowering.** Hoist each `zz_index_get` into a named temp with explicit `zz_release` after use (the `Index` fast path currently emits nested calls inline — confirm the inner temp outlives the outer under `-O3 -flto=thin` + `__atomic` refcounts). + +All three keep the `vec.push` copy-on-write contract (VM: input untouched) — add an assertion test for it. + +### 2.5 Bug 1 tests + +- Reduced fixture(s) from Phase 0 as `tests/fixtures/stdlib/vec_nested_str_push.zz` (+ struct variant `struct_nested_str_push.zz`), each printing all cells + trailing `_ok` marker, registered in `e2e.rs`. +- `dual_engine_parity.rs`: add nested-array cases (2-push, loop-push × N, struct-field, function-returned inner array, `x = vec.push(x, …)` self-reassign spelling + `x.push(…)` method spelling). +- ASan/UBSan gate (local, not CI): `clang -fsanitize=address,undefined` build of the reduced fixture must be clean; run the binary under `valgrind --tool=memcheck` if ASan is inconclusive. +- Existing known-failure: `move_append_struct_copy` — re-run; this fix should close it or document why not. + +## 3. Execution phases + +- **Phase 0 — harness (0.5d):** table demo fetched, native failure confirmed, reduced fixture, C dump attached, `ZZ_PARITY_VM_ONLY=1` baseline green. +- **Phase 1 — Bug 2 runtime (1d):** UTF-8 helpers + `zz_len`/`zz_str_length`/`zz_str_get`/`zz_slice_value`/`zz_str_split("")` + unit tests. No codegen changes. Verify `mini4` → `3/3/╭/─` on `--native`. +- **Phase 2 — Bug 1 root-cause + fix (2-3d):** Phase 0 reduction → pick A/B/C → implement in `collections.c` (+ `move_elide.rs`/`expr.rs` if lowering) → ASan clean → `mini1/mini2` + reduced fixture green at `-O0` and `-p`. +- **Phase 3 — parity suite (0.5d):** new fixtures registered, `dual_engine_parity` extended, full demo `zz run` vs `zz run --native` byte-identical, exit 0, no SIGSEGV. +- **Phase 4 — gate (0.5d):** `./scripts/test-fast.sh`, then `cargo test --all` if time allows, plus `cargo clippy --all-targets -- -D warnings` and `cargo fmt --check`. Update `docs/stdlib.md` (`len`/`str.length`/indexing = chars) and remove/refresh the "established engine difference" comments in `strings.h`. + +## 4. Suggested verification (from the bug report — Definition of Done) + +1. `mini1`/`mini2` print all four cells correctly with `--native`, no ``. +2. `mini4` prints `3 / 3 / ╭ / ─` with `--native`. +3. Full demo (`table/examples/demo.zz`: rounded + title/footer + `std.colors` + markdown) renders identically under `zz run` and `zz run --native`, exit 0, no SIGSEGV. +4. Suite stays green: `./scripts/test-fast.sh` (or `cargo test --all` if time allows) + `cargo clippy --all-targets -- -D warnings`, `cargo fmt --check`. + +## 5. Files to touch (expected) + +- `crates/zz_codegen/src/runtime/strings.h` — UTF-8 helpers + `zz_str_get` char-indexed. +- `crates/zz_codegen/src/runtime/strings.c` — `zz_str_length`, `zz_str_split("")`, helpers. +- `crates/zz_codegen/src/runtime/collections.c` — `zz_len`, `zz_len_field`, `zz_slice_value` (`ZZ_STR` arms); Bug 1 fix in `zz_vec_push_take`/`zz_object_push_field_take`/`zz_clone_for_store` (+ array-store healing). +- `crates/zz_codegen/src/lower/expr.rs` — only if Phase 0 shows a lowering lifetime bug (`Index` chain temps, `append_container_item` arena healing). +- `crates/zz_codegen/src/lower/move_elide.rs` — only if Phase 0 shows the `refs==1` gate is unsound (gate tightening). +- Tests: `crates/zz_cli/tests/e2e.rs` + `tests/fixtures/stdlib/str_utf8_*.zz` + `vec_nested_str_push.zz`, `crates/zz_cli/tests/dual_engine_parity.rs`, `crates/zz_codegen/src/tests.rs`, `crates/zz_stdlib/src/natives/tests.rs::str_length_counts_chars` (extend with UTF-8). +- Docs: `docs/stdlib.md`, comments in `strings.h`/`strings.c`/`collections.c`. + +## 6. Non-goals / follow-ups + +- Unicode `lower`/`upper`/`trim` parity (VM Unicode-aware vs AOT ASCII-only) — document, fix separately. +- Char-count caching in `zz_str` header (perf) — only if benchmarks regress. +- Table-pkg flat workaround (`cells:[str]` row-major + `nrows/ncols`) stays valid regardless; this branch removes the need for it on native. +- Chained index *stores* (`t.rows[0][0] = x`): VM drops the write into a temp + clone (read-back shows the old value), native writes through. Pre-existing + lowering-level divergence, untouched by this fix; new fixtures deliberately + cover reads only. Fix separately (either engine converging needs a + semantics decision + its own parity tests). + +## 7. Fix record (implemented on this branch) + +### Bug 2 — UTF-8 measure (VM parity restored) +- `runtime/strings.h`: new `zz_utf8_seq_len` / `zz_str_char_len` / + `zz_str_char_byte_off` helpers; `zz_str_get` rewritten char-indexed + (negative-aware, OOB → unit + err). Invalid bytes count as one + single-byte char each (never crash/loop). +- `runtime/strings.c`: `zz_str_length` returns chars; `zz_str_split` empty + separator emits per-char items AND matches Rust `split("")` exactly + (`"ab"` → `["", "a", "b", ""]`, `""` → `["", ""]`). +- `runtime/collections.c`: `zz_len` / `zz_len_field` (`ZZ_STR` arms) return + chars; `zz_slice_value` (`ZZ_STR` arm) normalizes + maps char bounds to + byte offsets. Byte-internal ops (concat/compare/print/hash) untouched. +- Verified: `mini4` → `3/3/╭/─` on `--native` (`-O0` and `-p -O3`); + extended edge fixture (negative index, slices, empty/ASCII, split empties) + byte-identical VM vs native. + +### Bug 1 — nested `[[str]]` arena aliasing (SIGSEGV fixed) +- Reproduced on `dev` HEAD: struct-field + loop push (`loopfield.zz`) + SIGSEGVs natively while VM passes. Root cause: inner literals use + `zz_array_new_arena_sized` (header + items on the loop arena); retaining + stores only healed strings, so the outer heap array aliased arena memory + and `zz_arena_reset` overwrote it (first-element garbage → tag corruption + → `` → SIGSEGV). Minimal 2-push repros pass because straight-line + temps are never released/reset. +- `runtime/collections.{h,c}`: `zz_array_is_arena` / `zz_dict_is_arena` + predicates; `zz_heal_for_move` (move convention: copy arena incl. deep + nested + wrapper lookthrough, adopt heap) and extended + `zz_clone_for_store` (share convention: copy arena, `zz_clone` heap); + depth-capped at 32.

Value model (decided first — everything else hangs off this) + +1.1. ZZ is a **value language**. Assignment, argument passing, and +return **copy**. After `y = x`, mutating through `y` MUST NOT be +observable through `x` — for scalars, strings, arrays, dicts, tuples, +structs, options, and results. The VM already behaves this way +(`move_append_struct_copy` prints the unaliased result); the AOT +backend's header-only struct clone is a bug under this rule. + +1.2. Sharing behind the scenes is allowed **iff unobservable**: COW, +move elision, arena allocation, and refcount sharing MUST preserve 1.1. +Concretely: a write through one binding MUST NOT leak into another +binding's storage. The existing `heal-on-escape` (arena → heap copy on +retaining stores) is the reference mechanism, generalized: any value +that outlives its allocating scope MUST be independently owned. + +1.3. Indexing yields a **copy**. `m[0]` evaluates to an owned value; +mutating it mutates nothing until stored back. + +1.4. Stores write through to the root binding. `m[0][0] = v` updates +`m` (the VM temp-clone drop is fixed; the AOT behavior is correct). +`Field`-under-`Index` (`s[0].v = x`) also writes through — the native +backend still drops these (tracked native bug, same class). + +1.5. Strings and bytes are immutable values. No operation mutates a +string in place; concatenation builds a new value. + +1.6. Closures capture **by reference to the variable**, not by value. +A closure and its defining scope observe each other's assignments to a +captured mutable variable. Each loop iteration creates a fresh binding +of the loop variable; closures created in different iterations capture +different variables. + +1.7. Representation is unspecified but observably equivalent to cells: +captured `const` or never-reassigned variables MAY be copied by value; +captured, reassigned variables of non-escaping closures MAY live in a +stack slot accessed by reference; captured, reassigned variables of +escaping closures use a shared reference-counted cell. Annotations +selecting a representation are hints — removing them MUST NOT change +program output (quad runs with `--strip-annotations` in M1 impl). + +1.8. `spawn` moves or copies captured variables into the new task at +spawn time. No mutable cell is implicitly shared across tasks; +cross-task sharing requires an explicit shared type (channels and +future shared handles, §1.7 of the pre-M1 report scope). + +1.7. Explicitly shared handles (channels, task joins, DB connections, +opaque native handles) are the ONLY aliasing exceptions. Their sharing +semantics live with their owning module spec, not here. + +## 2. Types and ops + +2.1. Scalar kinds: `I64`, `F64`, `BOOL`, `UNIT`. Composite values +(str, array, dict, tuple, struct, option, result, func, opaque) travel +through generic ops that dispatch to `zzrt`. + +2.2. Core ops are **typed**: `ADD_I64`, `SUB_I64`, `MUL_I64`, +`DIV_I64`, `REM_I64`, `NEG_I64`, `SHL_I64`, `SHR_I64` (arithmetic +shift), `AND_I64`/`OR_I64`/`XOR_I64`/`NOT_I64`, `ADD_F64`, …, +`CMP_I64` (lt/eq…), `CMP_F64`, `JMP_TRUE`/`JMP_FALSE` (bool only), +`CONV_F64_I64`, `CONV_I64_F64`, `CONV_STR_I64`, … The verifier knows +each op's stack type signature (§8). + +2.3. No `TRUTHY` op exists. Conditional jumps take `BOOL` only. The +checker guarantees bool conditions; the verifier rejects a +statically-non-bool condition; a dynamically-non-bool condition traps +`Type` (defensive — unreachable on checker-sound programs). + +## 3.

The `move_append_append` +fixture is now strict parity on both engines, and `docs/stdlib.md` +documents the alias row. + +## 8. Open design decisions / follow-ups + +1. **Native struct-clone sharing** (`move_append_struct_copy`, + `parity_known_failure`): `zz_clone` bumps only the object header + while `zz_release_object` frees field buffers — a cloned struct + shares field arrays at `arr->refs == 1`. Options: (a) deep-bump + retain (clone bumps field counters; touches every struct clone); + (b) COW field write (check-and-dup on set; touches every field + store); (c) keep value-divergence documented (status quo). The + take gate on the buffer counter is observably equivalent to the + generic path either way, so takes are safe regardless. +2. **Frozen-chain take/assign below a frozen level** drops the + intermediate frozen vars (same pre-existing shape as `assign_rec`); + takes only fire for frame-local homes so the path is nearly + unreachable — shares the fix with `assign` if ever addressed. +3. **Real-toml linearity** needs the parser-side index change (§5). +4. **`vec.insert` take fusion** (`x = vec.insert(x, i, v)`): small, + constant-factor only; worth doing with (3) or if insert-heavy + workloads appear. +5.
