description: Owns one feature, its assessment, decisions, verification, and submission.

# Feature coordinator
Own the problem and final verdict. Delegate execution, not judgment. Read relevant memory and repository instructions first.
For a small clear change, implement it yourself and run the required checks.
For a feature or exploration, assess first and change nothing until authorization arrives.
An assessment states complexity, approximate code delta, reuse, recommendation, a simpler alternative, risks, and numbered decisions.
Send it to @ultimate first. Ask the user after @ultimate recommends options, unless @ultimate supplies an authorized decision.
## Execution
After approval, use plan with binary acceptance criteria. Delegate independent reconnaissance to scout and bounded implementation to worker or designer.
A writing child gets a worktree. Each brief names the source repo, owned files, forbidden areas, known evidence, checks, and required report.
Never assign overlapping edits concurrently. Do not delegate requirements or the final verdict.
Inspect each child’s diff and actual check output. A claim or idle child is not evidence.
Land accepted workers into your checkout. Run the required checks on the combined result.
Give reviewer an immutable full-SHA base..head range, repo path, criteria, and validation evidence. Verify concrete findings yourself.
Children never push. Never commit, reset, or land in the user’s checkout to test a result.
Before workspace submit, report the outcome, exact checks, risks, and divergence from the task.
Every repository-specific branch or workspace operation must name the explicit source repo path.
If visual approval is required, ask the user for approval of the actual rendered result before submission.
P3 has no browser capture tools. Request images through the coordinator or user, and name any visual checks you cannot verify.
## Progress
While children run, state which replies you await. Never declare completion before their reports arrive.
End a turn only when a child, queued submission, or requested reply will wake you, or when you report a blocker.
A failed submission requires a fix at its cause. Never skip a check or extend its deadline to hide a failure.
## World contract
The world is one WASI sandbox. All agents see the same world. Use the programs in /bin through bash.
Use an explicit repo path for repository operations. Worktrees live at /worktrees/<id>.
The host injects credentials. A 403 requests approval through the host. Never read, store, or print secrets.
Agents write CLIs and servers. Do not add host imports beyond the process interface.

# Product designer
Solve the user’s stated problem within the assigned interface scope. Do not change backend contracts or dependencies without authorization.
Identify the user, their goal, the first thing they must notice, and the most important action.
Match existing patterns. Use hierarchy, spacing, readable text, and concrete action labels.
For CLIs, review help text, stdout, stderr, exit status, and long or empty output.
For web interfaces, cover empty, loading, error, long content, keyboard use, narrow widths, and applicable themes.
Keep existing behavior and required checks intact. Name departures from the brief instead of silently changing its scope.
Inspect rendered output before visual claims. P3 has no browser capture tools. Request screenshots from the coordinator or user.
If images are unavailable, report visual verification as unverified. Automated checks do not replace visual approval.
Do not delegate or push. Make one focused commit with --no-gpg-sign.
Report the outcome, design decisions, divergence, image paths, exact checks, and remaining risks.

# World agents and families
The built-in agent files live in `/src/sausage/agents/` in the world.
`models.json` is the world family file. It contains a map from each family to `model` and `thinking`.
Model references use proxy provider names, not subscription providers. The host owns credentials and injects them outside the world.
| Family | Model | Thinking |
| --- | --- | --- |
| default, fast | openai/gpt-6.1-sol | medium |
| review | anthropic/claude-opus-5-5 | xhigh |
| research, design, lead | anthropic/claude-opus-5-5 | high |
The default family selects its configured world model. It does not inherit a subscription model from the parent.
All independent reviewers use `review`. Architecture remains advisory. This choice follows D30 instead of Ultimate’s mixed-model defaults.
Scout uses `research`. Watcher uses `fast`. Worker and dream-pass retain `fast: true`.
## File order and overlays
The caller supplies fresh file contents and explicit paths on each discovery. The parser performs no I/O.
It reads sorted immediate `*.md` children of the built-in `agents/` directory, then `<repo>/.sausage/agents/`.
Later complete definitions replace earlier definitions by their frontmatter `name`, not their filename.
Invalid files produce errors and leave any earlier valid definition intact.
No user directory, trust layer, or additional extension roots participate.
An overlay has `name` and `addTools`. Use `addTools: []` for settings only. An overlay cannot contain `tools`.
Its settings replace earlier settings. Its tools and denials accumulate without duplicates.
Its body appends under `## Project additions`. The original definition retains its path and source.
A family overlay without a model removes an earlier model pin. Unknown families fall back to `default`.
A model pin overrides its family. Explicit thinking overrides a model suffix and family thinking.
Without explicit thinking or a suffix, a model pin has no requested thinking level.
The caller supplies the configured model catalog. Unknown model pins produce discovery errors.
`sausage-coordinator.md` ports Ultimate’s repo coordinator overlay. Its filename sorts after `coordinator.md`.
The eight base definitions plus three independent reviewers and this overlay total twelve files.
Do not rename the overlay before its base in lexical order.
## Parser contract and tests
`extensions/core/agents.ts` exports pure parse, discovery, overlay, family, and tool-selection functions.
It supports scalar fields and flow lists. It also supports block lists and folded descriptions from Ultimate’s parse tests.
It does not implement general YAML or a definition editor with serialization.
`toolsFor` filters supplied explicit or inherited tools without changes to the parent list.
The subagent extension still owns child-specific defaults and enforcement of the role instructions.
Tool lists and denials are workflow controls, not a new security boundary.
Run the tiny runner from this repository root with Node 24 or newer:
```sh
nix develop -c node extensions/core/agents.test.ts
```
The test runner uses Node filesystem and assertion APIs. The parser imports no Node APIs or packages.
Tests cover source parse errors, overlays, denials, model resolution, all twelve agent files, and all four skills.
These files define P3 behavior. They do not install the later runtime extensions or load the live world.

# Read-only dream pass
Your brief names one pass: memory, failures, tools, corrections, codify, or project.
Use its handoff, supplied conversation evidence, memory, and explicit repository files.
Start from summaries. Inspect individual evidence only where a summary points to a concrete issue.
Do not edit, commit, change state, message anyone, or delegate. Use bash only for inspection.
P3 supplies no history-query tool. If the handoff lacks conversation evidence, name that limitation rather than invent a query.
Report the overall finding, then prioritized findings with conversation ids, commits, or path:line citations and observed counts.
Propose one change per slug with a title, size, risk, and evidence.
Memory changes use add, update, or delete operations with reasons, but you do not apply them.
Codify proposals name the memory they replace. Project proposals name the explicit repo and existing code they reuse.
Never propose a storage chapter switch. Name all checks you cannot perform.

Ask whether the range uses Sausage architecture instead of a parallel mechanism.
Read AGENTS.md and relevant extension contracts before judgment.
Check standard WASI files, HTTP, and sockets. The process interface is the only extra host import.
Host code accesses the world through the VFS. Native work belongs only to the isolated Rust builder.
Agents write CLIs and servers. Repos use explicit paths. Durable tasks and events should reuse existing extension contracts.
Name the existing piece and simpler alternative with path:line evidence. Leave correctness to its reviewer.
This review is advisory. Always report APPROVED, even when verification is blocked, and clearly state that limitation.
Architecture findings are P3 and never block.
P0 means breakage, data loss, or exposed secrets. P1 means likely functional failure.
P2 blocks only when acceptance criteria require it. P3 means nonblocking polish.

Review the coordinator’s explicit repo, immutable full-SHA base..head range, and acceptance criteria.
A missing or ambiguous range blocks verification. Never substitute another range.
If reviewer-* definitions exist, start every one with the same brief. Do not share reports among reviewers.
Wait for complete answers. A failed or idle child without an answer counts as missing.

APPROVED requires approval from every reviewer. Otherwise report NEEDS CHANGES.
Without a team, inspect git log, git diff, and relevant unchanged logic yourself.

# Standing agent
You are Ultimate, the user’s standing agent in Sausage. Keep this conversation for the user and branch reports.
Read /src/sausage/AGENTS.md, agent files, skills, and relevant extension documents before answers about the platform.
Read the how-sausage-works skill when the user asks for a walkthrough.
## Branches and decisions
Write configuration and memory yourself. Send product code to a coordinator through branch.
Every branch brief names its repo path, goal, scope, acceptance criteria, and relevant memory slugs.
A small clear change needs targeted checks. A feature needs an assessment before implementation unless the user explicitly waived it.
After authorization, the coordinator plans, implements, verifies, reviews, and submits. Never declare success from an idle branch.
Route decisions through message with numbered questions. Let coordinators ask their own decisions after you state your recommendation.
Ask the user unless their instructions, memory, or active goal already settle the decision.
During a hands-off goal, record each decision and its authority with goal. Credentials and approvals remain the user’s responsibility.
Report a completed submission with its commit, checks, and divergence. Never push without authorization.
## Memory and open work
Use memory to read facts and remember to apply add, update, and delete operations.
Record durable decisions, not state that the prompt already supplies. Never store secrets in memory.
Use todo for open work, not unanswered questions. Use message for branch replies and notify for requested updates.
On a failed run, inspect the supplied failure evidence before you resume the agent or request user action.
Use compact with a self-contained handoff when context grows large.
A dream is a read-only review of evidence and memory. Approved proposals become ordinary branches. Do not switch storage chapters.
Use automation for schedules, event conditions, or supervised scripts. Verify its state with automation list.
When the user requests specialization, read integrate-sausage and adopt-sausage-workflow before proposals.

Acceptance criteria: each criterion with observed command output or path:line evidence.
Validation: exact commands and results. Name all unverified checks.
Commit: the full SHA and subject, or none.
Divergence: differences from the brief, or None.
Risks: remaining risks, or none.
DONE requires evidence for every criterion.
## World contract
The world is one WASI sandbox. All agents see the same world. Use the programs in /bin through bash.
Use an explicit repo path for repository operations. Worktrees live at /worktrees/<id>.
The host injects credentials. A 403 requests approval through the host. Never read, store, or print secrets.
Agents write CLIs and servers. Do not add host imports beyond the process interface.

# Credential script guest (D58)
This host-internal WASI component runs credential validators and transforms in QuickJS.
The host embeds `script.wasm`. It never exposes this component as a world program.
`src/lib.rs` ports v2's bounded `jsrun` evaluator.
`src/tests.rs` preserves its tests unchanged.
The vendored compatibility patches and licenses remain in `vendor/`.
`vendor/PATCHES.md` explains the compatibility fixes and memory-error classification.
Rebuild the checked-in component from the repository root:
```sh
CARGO_TARGET_DIR="$PWD/target/cred-guest" nix develop -c nu host/cred-script/build.nu
```
The script sets `CARGO_BUILD_JOBS=2` and uses the locked, separate guest workspace.
The development shell supplies the WASI C compiler and Rust target.
Run the unchanged evaluator tests natively:
```sh
CARGO_BUILD_JOBS=2 CARGO_TARGET_DIR="$PWD/target/cred-guest" nix develop -c cargo test --manifest-path host/cred-script/Cargo.toml --release --all-targets --locked
```
These tests use optimized C and Rust code, like the shipped guest.
Native debug builds exceed the 16 KiB interpreter stack.
The JSON protocol accepts one source module, input, export name, and two limits.
The reply contains a JSON result or a static error category.
Script exception text never leaves the guest.
The guest owns its input in zeroizing buffers before the QuickJS boundary.
The host compiles the component once and caches its compiled code.
Construct `cred::quickjs::QuickJs::default()` at startup and reuse it through `cred::script::Script`.
The injection API does not change.
Each call uses a fresh Store with linear memory limited to the clamped heap plus 8 MiB.
The margin covers the Rust stack, WASI adapter, and protocol buffers.
Only two evaluations run concurrently. Queue time counts against the deadline.
Epoch callbacks check each call's deadline independently.
The guest receives no directories, environment variables, or network access.
Its wall clock returns zero. Its random sources use a fixed seed.
Its monotonic clock serves the evaluator's internal budget only.
JavaScript receives no clocks, random function, module loader, or host interfaces.
`Error.prepareStackTrace` is disabled and immutable. Errors retain plain stack strings.

# Local compatibility patches
## LLRT utilities (SAU-330)
`llrt_buffer = 0.8.1-beta` and `llrt_encoding` remain published crate dependencies,
matching rquickjs 0.11 without changing the engine/vendor patches below.
The published `llrt_utils_watts = 0.8.1-beta` does not compile for wasm32-wasip2:
`signals::kill` unconditionally references `kill_process_raw` and `is_not_found`,
but those are only defined on Unix/Windows. The failed unpatched build is archived
at `/logs/cargo/2026-10-28/01a184d5-151b-7454-8333-b5d1d468b6d6.stderr.log`.
Fallback: `llrt_utils_watts/` is the unchanged published crate archive from
https://static.crates.io/crates/llrt_utils_watts/llrt_utils_watts-0.8.1-beta.crate
(SHA256 `5ace6f63a6b60a3bf738bf19f393c834c83a06d9e52c31d1c30a526584519569`),
except `src/lib.rs` adds `#[cfg(any(unix, windows))]` to `pub mod signals`.
The root Cargo patch points here. No utility module is registered as a JS module.
The upstream Apache-2.0 license is included (absent in the published archive).
This build-only patch does not alter Buffer. Before user module initialization,
the evaluator clears Buffer's global lexical binding and deletes its global-object
property, and removes Blob, File and Date, retaining only atob/btoa from the module.
SAU-330's mediator decision excludes the Node Buffer API rather than patching
its external-allocation heap bypass or empty-fill panic. Tests cover absent
identifiers, globalThis properties and global own-property names, plus base64
errors and clean near-heap-limit failure. See
`/docs/symphony/artifacts/SAU-330/implementation.md` for evidence.
## QuickJS (SAU-103)
`rquickjs-sys` was downloaded unchanged from https://crates.io/api/v1/crates/rquickjs-sys/0.11.0/download, then changed in exactly two files:
- `quickjs/quickjs.c`, `update_stack_limit`: remove the `__wasi__` special case that sets `stack_limit = 0` regardless of `JS_SetMaxStackSize`. Use the normal stack-top-minus-size implementation on WASI too. Without this patch the recursion test traps the WASM instance even with 16KiB / 256KiB limits. With the patch it returns `Maximum call stack size exceeded`.
- `build.rs`: skip upstream WASI SDK download/CC override when `CC_wasm32_wasip2` is supplied, letting `cc` honor cargo.build's target-specific CC/AR. Also emit the selected compiler/args as a diagnostic.
No engine features or host APIs were added. Keep this patch when reusing the evaluator; setting the Rust stack-limit API alone is **not sufficient** with unmodified rquickjs-sys 0.11.0. Upstream 0.14.0's source was inspected (not compiled) and still contains the WASI stack-limit bypass.
The bundled sources retain their upstream notices/licenses. This is a spike-local vendoring choice, not an SDK or live toolchain change.
## Sausage memory-error classification (D58)
`quickjs.c` records a sticky flag when `JS_ThrowOutOfMemory` runs.
`sausage_js_had_oom` exposes that flag to the guest's Rust evaluator.
`quickjs.h` declares this guest-internal function.
`build.rs` watches the QuickJS source directory, so Cargo rebuilds the library after a patch.
It adds no JavaScript API or host import.
A full heap can prevent QuickJS from creating its error object.
The unchanged `runaway_allocation` test reproduced that case and received `Throw` instead of `Limit`.
The flag preserves the memory-error category without another allocation.
Each evaluation creates a fresh runtime, so it also resets the flag.

copyright notice that is included in or attached to the work
(an example is provided in the Appendix below).
"Derivative Works" shall mean any work, whether in Source or Object
form, that is based on (or derived from) the Work and for which the
editorial revisions, annotations, elaborations, or other modifications

of this License, Derivative Works shall not include works that remain
separable from, or merely link (or bind by name) to the interfaces of,
the Work and Derivative Works thereof.
"Contribution" shall mean any work of authorship, including
the original version of the Work and any modifications or additions
to that Work or Derivative Works thereof, that is intentionally
submitted to Licensor for inclusion in the Work by the copyright owner
or by an individual or Legal Entity authorized to submit on behalf of
the copyright owner. For the purposes of this definition, "submitted"
means any form of electronic, verbal, or written communication sent

copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the
Work and such Derivative Works in Source or Object form.
3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works
that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained
within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

This crate is a low level unsafe raw bindings for the [QuickJS](https://bellard.org/quickjs/) JavaScript engine.
__NOTE:__ Usually you shouldn't use this crate directly, instead use [rquickjs](https://crates.io/crates/rquickjs) crate which provides high level safe bindings.
## Patches
In order to fix bugs and get support for some unimplemented features the series of patches applies to released sources.
Hot fixes:
- Fix for _check stack overflow_ (important for Rust)
- Atomic support for `JS_NewClassID` (important for Rust)
- Infinity handling (replacement `1.0 / 0.0` to `INFINITY` constant)
Special patches:
- Reading module exports (`exports` feature)
- Reset stack function (`parallel` feature)
- MSVC support

# ⚡️ QuickJS - A mighty JavaScript engine
## Overview
QuickJS is a small and embeddable JavaScript engine. It aims to support the latest
[ECMAScript] specification.
This project is a _fork_ of the [original QuickJS project] by Fabrice Bellard and Charlie Gordon, after it went dormant, with the intent of reigniting its development.
## Getting started
Head over to the [project website] for instructions on how to get started and more
documentation.
## Authors
[@bnoordhuis], [@saghul], and many more [contributors].
[ECMAScript]: https://tc39.es/ecma262/

# Building
QuickJS uses [CMake] as its main build system, with an additional helper [Makefile].
:::note
Windows users will need to run the CMake commands manually.
:::
## Getting the source
```bash
git clone https://github.com/quickjs-ng/quickjs.git
cd quickjs
```
## Compiling everything
```bash
make
```
This will build the `qjs` and `qjsc` executables and other test tools. Head over [here](./cli) for
instructions on how to use them.
## Amalgamated builds
The amalgamated build rolls individual source files into a single big file.
It's a good choice for projects that want to use QuickJS without CMake.
Download quickjs-amalgam.zip from [Releases](https://github.com/quickjs-ng/quickjs/releases)
To enable the std, os and bjson modules, compile quickjs-amalgam.c with
`-DQJS_BUILD_LIBC`.
## Debug builds
```bash
make debug
```
This will produce a debug build without optimizations, suitable for developers.
## Running test262
```bash
make test262
```
This will run the test262 suite.
```bash
make test262-update
```
This will run the test262 suite and update the error / pass report, useful after
implementing a new feature that would alter the result of the test suite.

-h --help list options
-e --eval EXPR evaluate EXPR
-i --interactive go to interactive mode
-m --module load as ES6 module (default=autodetect)

DUMP_ATOMS 0x40000 /* dump atoms in JS_FreeRuntime */
DUMP_SHAPES 0x80000 /* dump shapes in JS_FreeRuntime */
```
### Creating standalone executables
With the `qjs` CLI it's possible to create standalone executables that will bundle the given JavaScript file
alongside the binary.
```
$ qjs -c app.js -o app --exe qjs
```
The resulting `app` binary will have the same runtime dependencies as the `qjs` binary. This is acomplished
by compiling the target JavaScript file to bytecode and adding it a copy of the executable, with a little
trailer to help locate it. `--exe` expects the absolute path to `qjs`, e.g., `~/bin/qjs` or `$HOME/bin/qjs`.
Rather than using the current executable, it's possible to use the `--exe` switch to create standalone
executables for other platforms.
No JavaScript bundling is performed, the specified JS file cannot depend on other files. A bundler such
as `esbuild` can be used to generate an app bundle which can then be turned into the executable.
```
npx esbuild my-app/index.js \
--bundle \
--outfile=app.js \
--external:qjs:* \
--minify \
--target=es2023 \
--platform=neutral \
--format=esm \
--main-fields=main,module
```
## `qjsc` - The QuickJS JavaScript compiler
The `qjsc` executable runs the JavaScript compiler, it can generate bytecode from
source files which can then be embedded in an executable, or it can generate the necessary
scaffolding to build a C application which embeds QuickJS.
```
$ qjsc
usage: qjsc [options] [files]
options are:
-b output raw bytecode instead of C code
-e output main() and bytecode in a C file
-o output set the output filename
-n script_name set the script name (as used in stack traces)
-N cname set the C name of the generated data
-m compile as JavaScript module (default=autodetect)
-D module_name compile a dynamically loaded module or worker
-M module_name[,cname] add initialization code for an external C module
-p prefix set the prefix of the generated C names
-s strip the source code, specify twice to also strip debug info
-S n set the maximum stack size to 'n' bytes (default=262144)
```
Here is an example on how to create a standalone executable that embeds QuickJS
and the `examples/hello.js` JavaScript file:
```bash
# Make sure you are in the QuickJS source directory.
$ cc hello.c cutils.c dtoa.c libregexp.c libunicode.c quickjs.c quickjs-libc.c -I. -o hello
```
The resulting binary `hello` will be in the current directory.
```bash
$ ./hello
Hello World
```

# Internals
## Bytecode
The compiler generates bytecode directly with no intermediate
representation such as a parse tree, hence it is very fast. Several
optimizations passes are done over the generated bytecode.
A stack-based bytecode was chosen because it is simple and generates
compact code.
For each function, the maximum stack size is computed at compile time so that
no runtime stack overflow tests are needed.
A separate compressed line number table is maintained for the debug
information.
Access to closure variables is optimized and is almost as fast as local
variables.
Direct `eval` in strict mode is optimized.
## Runtime
### Strings
Strings are stored either as an 8 bit or a 16 bit array of
characters. Hence random access to characters is always fast.
The C API provides functions to convert JavaScript Strings to C UTF-8 encoded
strings. The most common case where the JavaScript string contains
only ASCII characters involves no copying.
### Objects
The object shapes (object prototype, property names and flags) are shared
between objects to save memory.
Arrays with no holes (except at the end of the array) are optimized.
TypedArray accesses are optimized.
### Atoms
Object property names and some strings are stored as Atoms (unique
strings) to save memory and allow fast comparison. Atoms are
represented as a 32 bit integer. Half of the atom range is reserved for
immediate integer literals from 0 to 2^31-1.
### Numbers
Numbers are represented either as 32-bit signed integers or 64-bit IEEE-754
floating point values. Most operations have fast paths for the 32-bit
integer case.
### Garbage collection
Reference counting is used to free objects automatically and
deterministically. A separate cycle removal pass is done when the allocated
memory becomes too large. The cycle removal algorithm only uses the
reference counts and the object content, so no explicit garbage
collection roots need to be manipulated in the C code.
### JSValue
It is a JavaScript value which can be a primitive type (such as
Number, String, ...) or an Object. NaN boxing is used in the 32-bit version
to store 64-bit floating point numbers. The representation is
optimized so that 32-bit integers and reference counted values can be
efficiently tested.
In 64-bit code, JSValue are 128-bit large and no NaN boxing is used. The
rationale is that in 64-bit code memory usage is less critical.
In both cases (32 or 64 bits), JSValue exactly fits two CPU registers,
so it can be efficiently returned by C functions.
### Function call
The engine is optimized so that function calls are fast. The system
stack holds the JavaScript parameters and local variables.
### RegExp
A specific regular expression engine was developed. It is both small
and efficient and supports all the ES2020+ features including the
Unicode properties. As the JavaScript compiler, it directly generates
bytecode without a parse tree.
Backtracking with an explicit stack is used so that there is no
recursion on the system stack. Simple quantifiers are specifically
optimized to avoid recursions.
Infinite recursions coming from quantifiers with empty terms are
avoided.
The full regexp library weighs about 15 KiB (x86 code), excluding the
Unicode library.
### Unicode
A specific Unicode library was developed so that there is no
dependency on an external large Unicode library such as ICU. All the
Unicode tables are compressed while keeping a reasonable access
speed.
The library supports case conversion, Unicode normalization, Unicode
script queries, Unicode general category queries and all Unicode
binary properties.
The full Unicode library weighs about 45 KiB (x86 code).
### BigInt
BigInt is implemented with the [libbf](https://bellard.org/libbf) library.
It weights about 90 KiB (x86 code) and provides arbitrary precision IEEE 754 floating
point operations and transcendental functions with exact rounding.

# The QuickJS C API
The C API was designed to be simple and efficient. The C API is
defined in the header `quickjs.h`.
## Runtime and contexts
`JSRuntime` represents a JavaScript runtime corresponding to an
object heap. Several runtimes can exist at the same time but they
cannot exchange objects. Inside a given runtime, no multi-threading is
supported.
`JSContext` represents a JavaScript context (or Realm). Each
JSContext has its own global objects and system objects. There can be
several JSContexts per JSRuntime and they can share objects, similar
to frames of the same origin sharing JavaScript objects in a
web browser.
## JSValue
`JSValue` represents a JavaScript value which can be a primitive
type or an object. Reference counting is used, so it is important to
explicitly duplicate (`JS_DupValue()`, increment the reference
count) or free (`JS_FreeValue()`, decrement the reference count)
JSValues.
## C functions
C functions can be created with
`JS_NewCFunction()`. `JS_SetPropertyFunctionList()` is a
shortcut to easily add functions, setters and getters properties to a
given object.
Unlike other embedded JavaScript engines, there is no implicit stack,
so C functions get their parameters as normal C parameters. As a
general rule, C functions take constant `JSValue`s as parameters
(so they don't need to free them) and return a newly allocated (=live)
`JSValue`.
## Exceptions
Most C functions can return a JavaScript exception. It
must be explicitly tested and handled by the C code. The specific
`JSValue` `JS_EXCEPTION` indicates that an exception
occurred. The actual exception object is stored in the
`JSContext` and can be retrieved with `JS_GetException()`.
## Script evaluation
Use `JS_Eval()` to evaluate a script or module source.
If the script or module was compiled to bytecode with `qjsc`, it
can be evaluated by calling `js_std_eval_binary()`. The advantage
is that no compilation is needed so it is faster and smaller because
the compiler can be removed from the executable if no `eval` is
required.
Note: the bytecode format is linked to a given QuickJS
version. Moreover, no security check is done before its
execution. Hence the bytecode should not be loaded from untrusted
sources.
## JS Classes
C opaque data can be attached to a JavaScript object. The type of the
C opaque data is determined with the class ID (`JSClassID`) of
the object. Hence the first step is to register a new class ID and JS
class (`JS_NewClassID()`, `JS_NewClass()`). Then you can
create objects of this class with `JS_NewObjectClass()` and get or
set the C opaque point with `JS_GetOpaque()` / `JS_SetOpaque()`.
When defining a new JS class, it is possible to declare a finalizer
which is called when the object is destroyed. The finalizer should be
used to release C resources. It is invalid to execute JS code from
it. A `gc_mark` method can be provided so that the cycle removal
algorithm can find the other objects referenced by this object. Other
methods are available to define exotic object behaviors.
The Class ID are allocated per-runtime. The
`JSClass` are allocated per `JSRuntime`. `JS_SetClassProto()`
is used to define a prototype for a given class in a given
`JSContext`. `JS_NewObjectClass()` sets this prototype in the
created object.
Examples are available in `quickjs-libc.c`.
## C Modules
Native ES6 modules are supported and can be dynamically or statically
linked. The standard library `quickjs-libc.c` is a good example
of a native module.
## Memory handling
Use `JS_SetMemoryLimit()` to set a global memory allocation limit
to a given `JSRuntime`.
Custom memory allocation functions can be provided with `JS_NewRuntime2()`.
The maximum system stack size can be set with `JS_SetMaxStackSize()`.
## Execution timeout and interrupts
Use `JS_SetInterruptHandler()` to set a callback which is
regularly called by the engine when it is executing code. This
callback can be used to implement an execution timeout.
It is used by the command line interpreter to implement a
`Ctrl-C` handler.

# Differences with bellard/quickjs
This project aims to be a drop-in replacement for those already using QuickJS.
Minimal API changes might be necessary.
## Community development
NG is developed in the open, interacting with the wider community and through
these interactions many improvements have already been made, including the incorporation
of patches previously maintained in other forks.
Each PR is reviewed, iterated on, and merged in GitHub.
To date, NG has had over 40 distinct contributors and over 400 PRs.
## Consistent release cadence
As the project moves forward, a steady cadence of releases has been maintained, with an
average of a new release every 2 months.
## Testing
Since its inception testing has been a focus. Each PR is tested in over 50 configurations,
involving different operating systems, build types and sanitizers.
The `test262` suite is also ran for every change.
## Cross-platform support
In order to better support other platforms such as Windows the build system was
changed to use [CMake].
In addition, Windows is treated as a first class citizen, with the addition of support
for the MSVC compiler.
[CMake]: https://cmake.org/
## Performance
While being an interpreter limits the performance in comparison with other engines which
use a JIT, several significant performance improvements have been made:
- Opcode fusion
- Polymorphic inline caching
- Memory allocation improvements
- Improved parse speeds
## New ECMAScript APIs
The main focus of NG is to deliver state-of-the-art JavaScript features. Typically once they
are stable (stage 4) but sometimes even at earlier stages. Here is a non-exhaustive list
of ES features present in NG:
- Resizable ArrayBuffer
- Float16Array
- WeakRef
- FinalizationRegistry
- Iterator Helpers
- Promise.try
- Error.isError
- Set operations
Some non-standard but widely used APIs have also been added:
- V8's [stack trace API](https://v8.dev/docs/stack-trace-api)
- `Error.captureStackTrace`
- `Error.prepareStackTrace`
- `Error.stackTraceLimit`

# ECMAScript Features
QuickJS aims to support the latest available ECMAScript features once they hit the spec.
Progress on _test262_ compliance can be checked [here](https://test262.fyi/#|qjs_ng).
Due to size constraints it is unlikely QuickJS will ever support the [Intl](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl) APIs.
