# Code style
All code is done with 2 spaces for indentation.
For cell script and its integration files, objects are preferred over classes, and preferrably limited use of prototypes, make objects sendable between actors (.ce files).
## cell script format
Cell script files end in .ce or .cm. Cell script is similar to Javascript but with some differences.
Variables are delcared with 'var'. Var behaves like let.
Constants are declared with 'def'.
!= and == are strict, there is no !== or ===.
There is no undefined, only null.
There are no classes, only objects and prototypes.
Prefer backticks for string interpolation. Otherwise, convering non strings with the text() function is required.
Everything should be lowercase.
There are no arraybuffers, only blobs, which work with bits. They must be stoned like stone(blob) before being read from.
## c format
For cell script integration files, everything should be declared static that can be. Most don't have headers at all. Files in a package are not shared between packages.
There is no undefined, so JS_IsNull and JS_NULL should be used only.
## how module loading is done in cell script
Within a package, a c file, if using the correct macros (CELL_USE_FUNCS etc), will be loaded as a module with its name; so png.c inside ac package is loaded as <package>/png, giving you access to its functions.

![image](/images/wizard.png)
ƿit is an actor-based scripting language for building concurrent applications. It combines a familiar C-like syntax with the actor model of computation, optimized for low memory usage and simplicity.
## Key Features
- **Actor Model** — isolated memory, message passing, no shared state
- **Immutability** — `stone()` makes values permanently frozen
- **Prototype Inheritance** — objects without classes
- **C Integration** — seamlessly extend with native code
- **Cross-Platform** — deploy to desktop, web, and embedded
## Quick Start
```javascript
// hello.ce - A simple actor
log.console("Hello, ƿit!")
$stop()
```
```bash
pit hello
```
## Language
- [**ƿit Language**](/docs/language/) — syntax, types, and built-in functions
- [**Actors and Modules**](/docs/actors/) — the execution model
- [**Packages**](/docs/packages/) — code organization and sharing
- [**Command Line**](/docs/cli/) — the `pit` tool
- [**Writing C Modules**](/docs/c-modules/) — native extensions
## Reference
- [**Built-in Functions**](/docs/functions/) — intrinsics reference
## Standard Library
- [text](/docs/library/text/) — string manipulation
- [number](/docs/library/number/) — numeric operations (functions are global: `floor()`, `max()`, etc.)
- [array](/docs/library/array/) — array utilities
- [object](/docs/library/object/) — object utilities
- [blob](/docs/library/blob/) — binary data
- [time](/docs/library/time/) — time and dates
- [math](/docs/library/math/) — trigonometry and math
- [json](/docs/library/json/) — JSON encoding/decoding
- [random](/docs/library/random/) — random numbers
## Architecture
ƿit programs are organized into **packages**. Each package contains:
- **Modules** (`.cm`) — return a value, cached and frozen
- **Actors** (`.ce`) — run independently, communicate via messages
- **C files** (`.c`) — compiled to native libraries
Actors never share memory. They communicate by sending messages, which are automatically serialized. This makes concurrent programming safe and predictable.
## Installation
```bash
# Clone and bootstrap
git clone https://gitea.pockle.world/john/cell
cd cell
make bootstrap
```
The ƿit shop is stored at `~/.pit/`.

```javascript

replace("hello", /l/g, "L")
text.replace("hello", /l/g, "L")
```
## Error Handling
ƿit uses `disrupt` and `disruption` for error handling. A `disrupt` signals that something went wrong. The `disruption` block attached to a function catches it.
```javascript
var safe_divide = function(a, b) {
if (b == 0) disrupt
return a / b
} disruption {
log.error("something went wrong")
try {
riskyOperation()
} catch (e) {
log.error(e)
}
throw "something went wrong"
```
`disrupt` is a bare keyword — it does not carry a value. The `disruption` block knows that something went wrong, but not what.
To test whether an operation disrupts:
```javascript
var should_disrupt = function(fn) {
var caught = false
var wrapper = function() {
fn()
} disruption {
caught = true
}
wrapper()
return caught
}
```
If an actor has an unhandled disruption, it crashes.
If an actor has an uncaught error, it crashes.

description: "Intrinsic constants and functions"
weight: 60
type: "docs"
---
The intrinsics are constants and functions that are built into the language. The `use` statement is not needed to access them.
A programmer is not obliged to consult the list of intrinsics before naming a new variable or input. New intrinsics may be added to ƿit without breaking existing programs.
## Constants
### false
The value of `1 == 0`. One of the two logical values.
### true
The value of `1 == 1`. One of the two logical values.
### null
The value of `1 / 0`. The null value is an empty immutable object. All attempts to obtain a value from null by refinement will produce null.
Any attempt to modify null will disrupt. Any attempt to call null as a function will disrupt.
null is the value of missing input values, missing fields in records, and invalid numbers.
### pi
An approximation of circumference / diameter: 3.1415926535897932.
## Creator Functions
The creator functions make new objects. Some can take various types. All return null if their inputs are not suitable.
### array
`array(number)` — Make an array. All elements are initialized to null.
`array(number, initial_value)` — Make an array. All elements are initialized to initial_value. If initial_value is a function, it is called for each element. If the function has arity >= 1, it is passed the element number.
```javascript
array(3) // [null, null, null]
array(3, 0) // [0, 0, 0]
array(5, i => i * 2) // [0, 2, 4, 6, 8]
```
`array(array)` — Copy. Make a mutable copy of the array.
`array(array, function, reverse, exit)` — Map. Call the function with each element, collecting return values in a new array. The function is passed each element and its element number.
```javascript
array([1, 2, 3], x => x * 10) // [10, 20, 30]
```
If reverse is true, starts with the last element and works backwards.
If exit is not null, when the function returns the exit value, array returns early. The exit value is not stored into the new array.
`array(array, another_array)` — Concat. Produce a new array concatenating both.
```javascript
array([1, 2], [3, 4]) // [1, 2, 3, 4]
```
`array(array, from, to)` — Slice. Make a mutable copy of part of an array. If from is negative, add length(array). If to is negative, add length(array).
```javascript
array([1, 2, 3, 4, 5], 1, 4) // [2, 3, 4]
array([1, 2, 3], -2) // [2, 3]
```
`array(record)` — Keys. Make an array containing all text keys in the record.
`array(text)` — Split text into grapheme clusters.
```javascript
array("hello") // ["h", "e", "l", "l", "o"]
```
`array(text, separator)` — Split text into an array of subtexts.
`array(text, length)` — Dice text into an array of subtexts of a given length.
### logical
```javascript
logical(0) // false
logical(false) // false
logical("false") // false
logical(null) // false
logical(1) // true
logical(true) // true
logical("true") // true
```
All other values return null.
### number
`number(logical)` — Returns 1 or 0.
`number(number)` — Returns the number.
`number(text, radix)` — Convert text to number. Radix is 2 thru 37 (default: 10).
`number(text, format)` — Parse formatted numbers:
| Format | Radix | Separator | Decimal point |
|--------|-------|-----------|---------------|
| `""` | 10 | | .period |
| `"n"` | 10 | | .period |
| `"u"` | 10 | _underbar | .period |
| `"d"` | 10 | ,comma | .period |
| `"s"` | 10 | space | .period |
| `"v"` | 10 | .period | ,comma |
| `"l"` | 10 | locale | locale |
| `"b"` | 2 | | |
| `"o"` | 8 | | |
| `"h"` | 16 | | |
| `"j"` | auto | | |
```javascript
number("123,456,789.10", "d") // 123456789.1
number("123.456.789,10", "v") // 123456789.1
number("666", "o") // 438
number("666", "h") // 1638
```
### text
`text(array, separator)` — Convert array to text. Elements are concatenated with the separator (default: empty text).
`text(number, radix)` — Convert number to text. Radix is 2 thru 37 (default: 10).
`text(number, format)` — Format a number as text:
**Real styles:**
| Style | Description | Separator | Decimal |
|-------|-------------|-----------|---------|
| `"e"` | Scientific | | .period |
| `"n"` | Number | | .period |
| `"s"` | Space | space | .period |
| `"u"` | Underbar | _underbar | .period |
| `"d"` | Decimal | ,comma | .period |
| `"c"` | Comma | .period | ,comma |
| `"l"` | Locale | locale | locale |
**Integer styles:**
| Style | Base | Separator |
|-------|------|-----------|
| `"i"` | 10 | _underbar |
| `"b"` | 2 | _underbar |
| `"o"` | 8 | _underbar |
| `"h"` | 16 | _underbar |
| `"t"` | 32 | _underbar |
The format text is: `separation_digit` + `style_letter` + `places_digits`
```javascript
var data = 123456789.1
text(data) // "123456789.1"
text(data, "3s4") // "123 456 789.1000"
text(data, "d2") // "123,456,789.10"
text(data, "e") // "1.234567891e8"
text(data, "i") // "123456789"
text(data, "8b") // "111_01011011_11001101_00010101"
text(data, "h") // "75BCD15"
text(12, "4b8") // "0000_1100"
```
`text(text, from, to)` — Extract a substring. If from/to are negative, add length(text).
```javascript
var my_text = "miskatonic"
text(my_text, 0, 3) // "mis"
text(my_text, 5) // "tonic"
text(my_text, -3) // "nic"
```
### record
`record(record)` — Copy. Make a mutable copy.
`record(record, another_record)` — Combine. Copy a record, then put all fields of another into the copy.
`record(record, array_of_keys)` — Select. New record with only the named fields.
`record(array_of_keys)` — Set. New record using array as keys, each value is true.
`record(array_of_keys, value)` — Value Set. Each field value is value.
`record(array_of_keys, function)` — Functional Value Set. The function is called for each key to produce field values.
## Sensory Functions
The sensory functions always return a logical value. In ƿit, they use the `is_` prefix:
```javascript
is_array([]) // true
is_blob(blob.make()) // true
is_function(x => x) // true
is_integer(42) // true
is_logical(true) // true
is_null(null) // true
is_number(3.14) // true
is_object({}) // true
is_text("hello") // true
```
Additional type checks: `is_character`, `is_data`, `is_digit`, `is_false`, `is_fit`, `is_letter`, `is_lower`, `is_pattern`, `is_stone`, `is_true`, `is_upper`, `is_whitespace`.
## Standard Functions
### abs(number)
Absolute value. Returns null for non-numbers.
### apply(function, array)
Execute the function, passing the array elements as input values. If the array is longer than the function's arity, it disrupts.
### ceiling(number, place)
Round up. If place is 0 or null, round to the smallest integer >= number.
```javascript
ceiling(12.3775) // 13
ceiling(12.3775, -2) // 12.38
ceiling(-12.3775) // -12
```
### character(value)
If text, returns the first character. If a non-negative 32-bit integer, returns the character from that codepoint.
### codepoint(text)
Returns the codepoint number of the first character.
### extract(text, pattern, from, to)
Match text to pattern. Returns a record of saved fields, or null if no match.
### fallback(requestor_array)
Returns a requestor that tries each requestor in order until one succeeds. Returns a cancel function.
### filter(array, function)
Call function for each element. When it returns true, the element is included in the new array.
```javascript
filter([0, 1.25, 2, 3.5, 4, 5.75], is_integer) // [0, 2, 4]
```
### find(array, function, reverse, from)
Call function for each element. If it returns true, return the element number. If the second argument is not a function, it is compared directly to elements. Returns null if not found.
```javascript
find([1, 2, 3], x => x > 1) // 1
find([1, 2, 3], 2) // 1
```
### floor(number, place)
Round down. If place is 0 or null, round to the greatest integer <= number.
```javascript
floor(12.3775) // 12
floor(12.3775, -2) // 12.37
floor(-12.3775) // -13
```
### for(array, function, reverse, exit)
Call function with each element and its element number. If exit is not null and the function returns the exit value, return early.
### format(text, collection, transformer)
Substitute `{key}` placeholders in text with values from a collection (array or record).
```javascript
format("{0} in {1}!", ["Malmborg", "Plano"])
// "Malmborg in Plano!"
```
### fraction(number)
Returns the fractional part of a number. See also `whole`.
### length(value)
| Value | Result |
|-------|--------|
| array | number of elements |
| blob | number of bits |
| text | number of codepoints |
| function | number of named inputs (arity) |
| record | record.length() |
| other | null |
### lower(text)
Returns text with all uppercase characters converted to lowercase.
### max(number, number)
Returns the larger of two numbers. Returns null if either is not a number.
### min(number, number)
Returns the smaller of two numbers.
### modulo(dividend, divisor)
Result is `dividend - (divisor * floor(dividend / divisor))`. Result has the sign of the divisor.
### neg(number)
Negate. Reverse the sign of a number.
### normalize(text)
Unicode normalize.
### not(logical)
Returns the opposite logical. Returns null for non-logicals.
### parallel(requestor_array, throttle, need)
Returns a requestor that starts all requestors in the array. Results are collected into an array matching the input order. Optional throttle limits concurrent requestors. Optional need specifies the minimum number of successes required.
### race(requestor_array, throttle, need)
Like parallel, but returns as soon as the needed number of results are obtained. Default need is 1. Unfinished requestors are cancelled.
### reduce(array, function, initial, reverse)
Reduce an array to a single value by applying a function to pairs of elements.
```javascript
reduce([1, 2, 3, 4, 5, 6, 7, 8, 9], (a, b) => a + b) // 45
```
### remainder(dividend, divisor)
For fit integers: `dividend - ((dividend // divisor) * divisor)`.
### replace(text, target, replacement, limit)
Return text with target replaced by replacement. Target can be text or pattern. Replacement can be text or a function.
### reverse(array)
Returns a new array with elements in the opposite order.
### round(number, place)
Round to nearest.
```javascript
round(12.3775) // 12
round(12.3775, -2) // 12.38
```
### search(text, target, from)
Search text for target. Returns character position or null.
### sequence(requestor_array)
Returns a requestor that processes each requestor in order. Each result becomes the input to the next. The last result is the final result.
### sign(number)
Returns -1, 0, or 1.
### sort(array, select)
Returns a new sorted array. Sort keys must be all numbers or all texts. Sort is ascending and stable.
| select type | Sort key | Description |
|-------------|----------|-------------|
| null | element itself | Simple sort |
| text | element[select] | Sort by record field |
| number | element[select] | Sort by array index |
| array | select[index] | External sort keys |
```javascript
sort(["oats", "peas", "beans", "barley"])
// ["barley", "beans", "oats", "peas"]
sort([{n: 3}, {n: 1}], "n")
// [{n: 1}, {n: 3}]
```
### stone(value)
Petrify the value, making it permanently immutable. The operation is deep — all nested objects and arrays are also frozen. Returns the value.
### trim(text, reject)
Remove characters from both ends. Default removes whitespace.
### trunc(number, place)
Truncate toward zero.
```javascript
trunc(12.3775) // 12
trunc(-12.3775) // -12
```
### upper(text)
Returns text with all lowercase characters converted to uppercase.
### whole(number)
Returns the whole part of a number. See also `fraction`.

# Cell
![image](wizard.png)
Cell is an actor-based scripting language for building concurrent applications. It combines a familiar JavaScript-like syntax with the actor model of computation.
## Key Features
- **Actor Model** — isolated memory, message passing, no shared state
- **Immutability** — `stone()` makes values permanently frozen
- **Prototype Inheritance** — objects without classes
- **C Integration** — seamlessly extend with native code
- **Cross-Platform** — deploy to desktop, web, and embedded
## Quick Start
```javascript
// hello.ce - A simple actor
log.console("Hello, Cell!")
$stop()
```
```bash
cell hello
```
## Documentation
- [**Cell Language**](cellscript.md) — syntax, types, and built-in functions
- [**Actors and Modules**](actors.md) — the execution model
- [**Packages**](packages.md) — code organization and sharing
- [**Command Line**](cli.md) — the `cell` tool
- [**Writing C Modules**](c-modules.md) — native extensions
## Standard Library
- [text](library/text.md) — string manipulation
- [number](library/number.md) — numeric operations
- [array](library/array.md) — array utilities
- [object](library/object.md) — object utilities
- [blob](library/blob.md) — binary data
- [time](library/time.md) — time and dates
- [math](library/math.md) — trigonometry and math
- [json](library/json.md) — JSON encoding/decoding
- [random](library/random.md) — random numbers
## Architecture
Cell programs are organized into **packages**. Each package contains:
- **Modules** (`.cm`) — return a value, cached and frozen
- **Actors** (`.ce`) — run independently, communicate via messages
- **C files** (`.c`) — compiled to native libraries
Actors never share memory. They communicate by sending messages, which are automatically serialized. This makes concurrent programming safe and predictable.
## Installation
```bash
# Clone and bootstrap
git clone https://gitea.pockle.world/john/cell
cd cell
make bootstrap
```
The Cell shop is stored at `~/.cell/`.

title: "Kim Encoding"
description: "Compact character and count encoding"
weight: 80
type: "docs"
---
Kim is a character and count encoding designed by Douglas Crockford. It encodes Unicode characters and variable-length integers using continuation bytes. Kim is simpler and more compact than UTF-8 for most text.
## Continuation Bytes
The fundamental idea in Kim is the continuation byte:
```
C D D D D D D D
```
- **C** — continue bit. If 1, read another byte. If 0, this is the last byte.
- **D** (7 bits) — data bits.
To decode: shift the accumulator left by 7 bits, add the 7 data bits. If the continue bit is 1, repeat with the next byte. If 0, the value is complete.
To encode: take the value, emit 7 bits at a time from most significant to least significant, setting the continue bit on all bytes except the last.
## Character Encoding
Kim encodes Unicode codepoints directly as continuation byte sequences:
| Range | Bytes | Characters |
|-------|-------|------------|
| U+0000 to U+007F | 1 | ASCII |
| U+0080 to U+3FFF | 2 | First quarter of BMP |
| U+4000 to U+10FFFF | 3 | All other Unicode |
Unlike UTF-8, there is no need for surrogate pairs or escapement. Every Unicode character, including emoji and characters from extended planes, is encoded in at most 3 bytes.
### Examples
```
'A' (U+0041) → 41
'é' (U+00E9) → 81 69
'💩' (U+1F4A9) → 87 E9 29
```
## Count Encoding
Kim is also used for encoding counts (lengths, sizes). The same continuation byte format represents non-negative integers of arbitrary size:
| Range | Bytes |
|-------|-------|
| 0 to 127 | 1 |
| 128 to 16383 | 2 |
| 16384 to 2097151 | 3 |
## Comparison with UTF-8
| Property | Kim | UTF-8 |
|----------|-----|-------|
| ASCII | 1 byte | 1 byte |
| BMP (first quarter) | 2 bytes | 2-3 bytes |
| Full Unicode | 3 bytes | 3-4 bytes |
| Self-synchronizing | No | Yes |
| Sortable | No | Yes |
| Simpler to implement | Yes | No |
| Byte count for counts | Variable (7 bits/byte) | Not applicable |
Kim trades self-synchronization (the ability to find character boundaries from any position) for simplicity and compactness. In practice, Kim text is accessed sequentially, so self-synchronization is not needed.
## Usage in ƿit
Kim is used internally by blobs and by the Nota message format.
### In Blobs
The `blob.write_text` and `blob.read_text` functions use Kim to encode text into binary data:
```javascript
var blob = use('blob')
var b = blob.make()
blob.write_text(b, "hello") // Kim-encoded length + characters
stone(b)
var text = blob.read_text(b, 0) // "hello"
```
### In Nota
Nota uses Kim for two purposes:
1. **Counts** — array lengths, text lengths, blob sizes, record pair counts
2. **Characters** — text content within Nota messages
The preamble byte of each Nota value incorporates the first few bits of a Kim-encoded count, with the continue bit indicating whether more bytes follow.
See [Nota Format](#nota) for the full specification.

Nota is a binary message format developed for use in the Procession Protocol. It provides a compact, JSON-like encoding that supports blobs, text, arrays, records, numbers, and symbols.
Nota stands for Network Object Transfer Arrangement.
## Design Philosophy
JSON had three design rules: minimal, textual, and subset of JavaScript. The textual and JavaScript rules are no longer necessary. Nota maintains JSON's philosophy of being at the intersection of most programming languages and most data types, but departs by using counts instead of brackets and binary encoding instead of text.
Nota uses Kim continuation bytes for counts and character encoding. See [Kim Encoding](#kim) for details.
## Type Summary
| Bits | Type |
|------|------|
| `000` | Blob |
| `001` | Text |
| `010` | Array |
| `011` | Record |
| `100` | Floating Point (positive exponent) |
| `101` | Floating Point (negative exponent) |
| `110` | Integer (zero exponent) |
| `111` | Symbol |
## Preambles
Every Nota value starts with a preamble byte that is a Kim value with the three most significant bits used for type information.
Most types provide 3 or 4 data bits in the preamble. If the Kim encoding of the data fits in those bits, it is incorporated directly and the continue bit is off. Otherwise the continue bit is on and the continuation follows.
## Blob
```
C 0 0 0 D D D D
```
- **C** — continue the number of bits
- **DDDD** — the number of bits
A blob is a string of bits. The data produces the number of bits. The number of bytes that follow: `floor((number_of_bits + 7) / 8)`. The final byte is padded with 0 if necessary.
Example: A blob containing 25 bits `1111000011100011001000001`:
```
80 19 F0 E3 20 80
```
## Text
```
C 0 0 1 D D D D
```
- **C** — continue the number of characters
- **DDDD** — the number of characters
The data produces the number of characters. Kim-encoded characters follow. ASCII characters are 1 byte, first quarter BMP characters are 2 bytes, all other Unicode characters are 3 bytes. Unlike JSON, there is never a need for escapement.
Examples:
```
"" → 10
"cat" → 13 63 61 74
```
## Array
```
C 0 1 0 D D D D
```
- **C** — continue the number of elements
- **DDDD** — the number of elements
An array is an ordered sequence of values. Following the preamble are the elements, each beginning with its own preamble. Nesting is encouraged.
## Record
```
C 0 1 1 D D D D
```
- **C** — continue the number of pairs
- **DDDD** — the number of pairs
A record is an unordered collection of key/value pairs. Keys must be text and must be unique within the record. Values can be any Nota type.
## Floating Point
```
C 1 0 E S D D D
```
- **C** — continue the exponent
- **E** — sign of the exponent
- **S** — sign of the coefficient
- **DDD** — three bits of the exponent
Nota floating point represents numbers as `coefficient * 10^exponent`. The coefficient must be an integer. The preamble may contain the first three bits of the exponent, followed by the continuation of the exponent (if any), followed by the coefficient.
Use the integer type when the exponent is zero.
Examples:
```
-1.01 → 5A 65
98.6 → 51 87 5A
-0.5772156649 → D8 0A 95 C0 B0 BD 69
-10000000000000 → C8 0D 01
```
## Integer
```
C 1 1 0 S D D D
```
- **C** — continue the integer
- **S** — sign
- **DDD** — three bits of the integer
Integers in the range -7 to 7 fit in a single byte. Integers in the range -1023 to 1023 fit in two bytes. Integers in the range -131071 to 131071 fit in three bytes.
Examples:
```
0 → 60
2023 → E0 8F 67
-1 → 69
```
## Symbol
```
0 1 1 1 D D D D
```
- **DDDD** — the symbol
There are currently five symbols:
```
null → 70
false → 72
true → 73
private → 78
system → 79
```
The private prefix must be followed by a record containing a private process address. The system prefix must be followed by a record containing a system message. All other symbols are reserved.

title: "Requestors"
description: "Asynchronous work with requestors"
weight: 25
type: "docs"
---
Requestors are functions that encapsulate asynchronous work. They provide a structured way to compose callbacks, manage cancellation, and coordinate concurrent operations between actors.
## What is a Requestor
A requestor is a function with this signature:
```javascript
function my_requestor(callback, value) {
// Do async work, then call callback with result
// Return a cancel function
}
```
- **callback** — called when the work completes: `callback(value, reason)`
- On success: `callback(result)` or `callback(result, null)`
- On failure: `callback(null, reason)` where reason explains the failure
- **value** — input passed from the previous step (or the initial caller)
- **return** — a cancel function, or null if cancellation is not supported
The cancel function, when called, should abort the in-progress work.
## Writing a Requestor
```javascript
function fetch_data(callback, url) {
$contact(function(connection) {
$send(connection, {get: url}, function(response) {
callback(response)
})
}, {host: url, port: 80})
return function cancel() {
// clean up if needed
}
}
```
A requestor that always succeeds immediately:
```javascript
function constant(callback, value) {
callback(42)
}
```
A requestor that always fails:
```javascript
function broken(callback, value) {
callback(null, "something went wrong")
}
```
## Composing Requestors
ƿit provides four built-in functions for composing requestors into pipelines.
### sequence(requestor_array)
Run requestors one after another. Each result becomes the input to the next. The final result is passed to the callback.
```javascript
var pipeline = sequence([
fetch_user,
validate_permissions,
load_profile
])
pipeline(function(profile, reason) {
if (reason) {
log.error(reason)
} else {
log.console(profile.name)
}
}, user_id)
```
If any step fails, the remaining steps are skipped and the failure propagates.
### parallel(requestor_array, throttle, need)
Start all requestors concurrently. Results are collected into an array matching the input order.
```javascript
var both = parallel([
fetch_profile,
fetch_settings
])
both(function(results, reason) {
var profile = results[0]
var settings = results[1]
}, user_id)
```
- **throttle** — limit how many requestors run at once (null for no limit)
- **need** — minimum number of successes required (default: all)
### race(requestor_array, throttle, need)
Like `parallel`, but returns as soon as the needed number of results arrive. Unfinished requestors are cancelled.
```javascript
var fastest = race([
fetch_from_cache,
fetch_from_network,
fetch_from_backup
])
fastest(function(results) {
// results[0] is whichever responded first
}, request)
```
Default need is 1. Useful for redundant operations where only one result matters.
### fallback(requestor_array)
Try each requestor in order. If one fails, try the next. Return the first success.
```javascript
var resilient = fallback([
fetch_from_primary,
fetch_from_secondary,
use_cached_value
])
resilient(function(data, reason) {
if (reason) {
log.error("all sources failed")
}
}, key)
```
## Timeouts
Wrap any requestor with `$time_limit` to add a timeout:
```javascript
var timed = $time_limit(fetch_data, 5) // 5 second timeout
timed(function(result, reason) {
// reason will explain timeout if it fires
}, url)
```
If the requestor does not complete within the time limit, it is cancelled and the callback receives a failure.
## Requestors and Actors
Requestors are particularly useful with actor messaging. Since `$send` is callback-based, it fits naturally:
```javascript
function ask_worker(callback, task) {
$send(worker, task, function(reply) {
callback(reply)
})
}
var pipeline = sequence([
ask_worker,
process_result,
store_result
])
pipeline(function(stored) {
log.console("done")
$stop()
}, {type: "compute", data: [1, 2, 3]})
```

title: "Bytecode VM"
description: "Stack-based virtual machine"
---
## Overview
The bytecode VM is a stack-based virtual machine. Instructions operate on an implicit operand stack, pushing and popping values. This is the original execution backend for ƿit.
## Compilation Pipeline
```
Source → Tokenize → Parse (AST) → Bytecode → Link → Execute
```
The compiler emits `JSFunctionBytecode` objects containing opcode sequences, constant pools, and debug information.
## Instruction Categories
### Value Loading
| Opcode | Description |
|--------|-------------|
| `push_i32` | Push a 32-bit immediate integer |
| `push_const` | Push a value from the constant pool |
| `null` | Push null |
| `push_false` | Push false |
| `push_true` | Push true |
### Stack Manipulation
| Opcode | Description |
|--------|-------------|
| `drop` | Remove top of stack |
| `dup` | Duplicate top of stack |
| `dup1` / `dup2` / `dup3` | Duplicate item at depth |
| `swap` | Swap top two items |
| `rot3l` / `rot3r` | Rotate top three items |
| `insert2` / `insert3` | Insert top item deeper |
| `nip` | Remove second item |
### Variable Access
| Opcode | Description |
|--------|-------------|
| `get_var` | Load variable by name (pre-link) |
| `put_var` | Store variable by name (pre-link) |
| `get_loc` / `put_loc` | Access local variable by index |
| `get_arg` / `put_arg` | Access function argument by index |
| `get_env_slot` / `set_env_slot` | Access closure variable (post-link) |
| `get_global_slot` / `set_global_slot` | Access global variable (post-link) |
Variable access opcodes are patched during linking. `get_var` instructions are rewritten to `get_loc`, `get_env_slot`, or `get_global_slot` depending on where the variable is resolved.
### Arithmetic
| Opcode | Description |
|--------|-------------|
| `add` / `sub` / `mul` / `div` | Basic arithmetic |
| `mod` / `pow` | Modulo and power |
| `neg` / `inc` / `dec` | Unary operations |
| `add_loc` / `inc_loc` / `dec_loc` | Optimized local variable update |
### Comparison and Logic
| Opcode | Description |
|--------|-------------|
| `strict_eq` / `strict_neq` | Equality (ƿit uses strict only) |
| `lt` / `lte` / `gt` / `gte` | Ordered comparison |
| `not` / `lnot` | Logical / bitwise not |
| `and` / `or` / `xor` | Bitwise operations |
### Control Flow
| Opcode | Description |
|--------|-------------|
| `goto` | Unconditional jump |
| `if_true` / `if_false` | Conditional jump |
| `goto8` / `goto16` | Short jumps (size-optimized) |
| `if_true8` / `if_false8` | Short conditional jumps |
| `catch` | Set exception handler |
### Function Calls
| Opcode | Description |
|--------|-------------|
| `call` | Call function with N arguments |
| `tail_call` | Tail-call optimization |
| `call_method` | Call method on object |
| `return` | Return value from function |
| `return_undef` | Return null from function |
| `throw` | Throw exception (disrupt) |
### Property Access
| Opcode | Description |
|--------|-------------|
| `get_field` | Get named property |
| `put_field` | Set named property |
| `get_array_el` | Get computed property |
| `put_array_el` | Set computed property |
| `define_field` | Define property during object literal |
### Object Creation
| Opcode | Description |
|--------|-------------|
| `object` | Create new empty object |
| `array_from` | Create array from stack values |
## Bytecode Patching
During the link/integrate phase, symbolic variable references are resolved to concrete access instructions. This is a critical optimization — the interpreter does not perform name lookups at runtime.
A `get_var "x"` instruction becomes:
- `get_loc 3` — if x is local variable at index 3
- `get_env_slot 1, 5` — if x is captured from outer scope (depth 1, slot 5)
- `get_global_slot 7` — if x is a global

title: "DEC64 Numbers"
description: "Decimal floating point representation"
---
## Overview
ƿit uses DEC64 as its number format. DEC64 represents numbers as `coefficient * 10^exponent` in a 64-bit word. This eliminates the rounding errors that plague IEEE 754 binary floating point — `0.1 + 0.2` is exactly `0.3`.
DEC64 was designed by Douglas Crockford as a general-purpose number type suitable for both business and scientific computation.
## Format
A DEC64 number is a 64-bit value:
```
[coefficient: 56 bits][exponent: 8 bits]
```
- **Coefficient** — a 56-bit signed integer (two's complement)
- **Exponent** — an 8-bit signed integer (range: -127 to 127)
The value of a DEC64 number is: `coefficient * 10^exponent`
### Examples
| Value | Coefficient | Exponent | Hex |
|-------|------------|----------|-----|
| `0` | 0 | 0 | `0000000000000000` |
| `1` | 1 | 0 | `0000000000000100` |
| `3.14159` | 314159 | -5 | `000000004CB2FFFB` |
| `-1` | -1 | 0 | `FFFFFFFFFFFFFF00` |
| `1000000` | 1 | 6 | `0000000000000106` |
## Special Values
### Null
The exponent `0x80` (-128) indicates null. This is the only special value — there is no infinity, no NaN, no negative zero. Operations that would produce undefined results (such as division by zero) return null.
```
coefficient: any, exponent: 0x80 → null
```
## Arithmetic Properties
- **Exact decimals**: All decimal fractions with up to 17 significant digits are represented exactly
- **No rounding**: `0.1 + 0.2 == 0.3` is true
- **Integer range**: Exact integers up to 2^55 (about 3.6 * 10^16)
- **Normalized on demand**: The runtime normalizes coefficients to remove trailing zeros when needed for comparison
## Comparison with IEEE 754
| Property | DEC64 | IEEE 754 double |
|----------|-------|----------------|
| Decimal fractions | Exact | Approximate |
| Significant digits | ~17 | ~15-16 |
| Special values | null only | NaN, ±Infinity, -0 |
| Rounding errors | None (decimal) | Common |
| Financial arithmetic | Correct | Requires libraries |
| Scientific range | ±10^127 | ±10^308 |
DEC64 trades a smaller exponent range for exact decimal arithmetic. Most applications never need exponents beyond ±127.
## In ƿit
All numbers in ƿit are DEC64. There is no separate integer type at the language level — the distinction is internal. The `is_integer` function checks whether a number has no fractional part.
```javascript
var x = 42 // coefficient: 42, exponent: 0
var y = 3.14 // coefficient: 314, exponent: -2
var z = 1000000 // coefficient: 1, exponent: 6 (normalized)
is_integer(x) // true
is_integer(y) // false
1 / 0 // null
```

title: "Garbage Collection"
description: "Cheney copying collector"
---
## Overview
ƿit uses a Cheney copying collector for automatic memory management. Each actor has its own independent heap — actors never share mutable memory, so garbage collection is per-actor with no global pauses.
## Algorithm
The Cheney algorithm is a two-space copying collector:
1. **Allocate new space** — a fresh memory block for the new heap
2. **Copy roots** — copy all live root objects from old space to new space
3. **Scan** — walk the new space, updating all internal references
4. **Free old space** — the entire old heap is freed at once
### Copying and Forwarding
When an object is copied from old space to new space:
1. The object's data is copied to the next free position in new space
2. The old object's header is overwritten with a **forwarding pointer** (`OBJ_FORWARD`) containing the new address
3. Future references to the old address find the forwarding pointer and follow it to the new location
```
Old space: New space:
┌──────────────┐ ┌──────────────┐
│ OBJ_FORWARD ─┼────────> │ copied object│
│ (new addr) │ │ │
└──────────────┘ └──────────────┘
```
### Scan Phase
After roots are copied, the collector scans new space linearly. For each object, it examines every JSValue field:
- If the field points to old space, copy the referenced object (or follow its forwarding pointer if already copied)
- If the field points to stone memory, skip it (stone objects are permanent)
- If the field is an immediate value (integer, boolean, null, immediate string), skip it
The scan continues until the scan pointer catches up with the allocation pointer — at that point, all live objects have been found and copied.
## Roots
The collector traces from these root sources:
- **Global object** — all global variables
- **Class prototypes** — built-in type prototypes
- **Exception** — the current exception value
- **Value stack** — all values on the operand stack
- **Frame stack** — all stack frames (bytecode and register VM)
- **GC reference stack** — manually registered roots (via `JS_PUSH_VALUE` / `JS_POP_VALUE`)
- **Parser constant pool** — during compilation, constants being built
## Per-Actor Heaps
Each actor maintains its own heap with independent collection:
- No stop-the-world pauses across actors
- No synchronization between collectors
- Each actor's GC runs at the end of a turn (between message deliveries)
- Heap sizes adapt independently based on each actor's allocation patterns
## Heap Growth
The collector uses a buddy allocator for heap blocks. After each collection, if less than 20% of the heap was recovered, the next block size is doubled. The new space size is: `max(live_estimate + alloc_size, next_block_size)`.
All allocations within a heap block use bump allocation (advance a pointer), which is extremely fast.
## Alignment
All objects are aligned to 8-byte boundaries. Object sizes are rounded up to ensure this alignment, which guarantees that the low 3 bits of any heap pointer are always zero — available for JSValue tag bits.
## Interaction with Stone Memory
Stone memory objects (S bit set) are never copied by the collector. When the scanner encounters a pointer to stone memory, it leaves it unchanged. This means:
- Stone objects are effectively permanent GC roots
- No overhead for tracing through immutable object graphs
- Module return values and interned strings impose zero GC cost

title: "Register VM"
description: "Register-based virtual machine (Mach)"
---
## Overview
The Mach VM is a register-based virtual machine using 32-bit instructions. It is modeled after Lua's register VM — operands are register indices rather than stack positions, reducing instruction count and improving performance.
## Instruction Formats
All instructions are 32 bits wide. Four encoding formats are used:
### iABC — Three-Register
```
[op: 8][A: 8][B: 8][C: 8]
```
Used for operations on three registers: `R(A) = R(B) op R(C)`.
### iABx — Register + Constant
```
[op: 8][A: 8][Bx: 16]
```
Used for loading constants: `R(A) = K(Bx)`.
### iAsBx — Register + Signed Offset
```
[op: 8][A: 8][sBx: 16]
```
Used for conditional jumps: if `R(A)` then jump by `sBx`.
### isJ — Signed Jump
```
[op: 8][sJ: 24]
```
Used for unconditional jumps with a 24-bit signed offset.
## Registers
Each function frame has a fixed number of register slots, determined at compile time. Registers hold:
- **R(0)** — `this` binding
- **R(1)..R(arity)** — function arguments
- **R(arity+1)..** — local variables and temporaries

uint16_t nr_slots; // total register count
uint32_t cpool_count; // constant pool size
JSValue *cpool; // constant pool
uint32_t instr_count; // instruction count
MachInstr32 *instructions; // 32-bit instruction array
uint32_t func_count; // nested function count
JSCodeRegister **functions; // nested function table
JSValue name; // function name
uint16_t disruption_pc; // exception handler offset
};
```
The constant pool holds all non-immediate values referenced by `LOADK` instructions: strings, large numbers, and other constants.

title: "Mcode IR"
description: "JSON-based intermediate representation"
---
## Overview
Mcode is a JSON-based intermediate representation that can be interpreted directly. It represents the same operations as the Mach register VM but uses string-based instruction dispatch rather than binary opcodes. Mcode is intended as an intermediate step toward native code compilation.
## Pipeline
```
Source → Tokenize → Parse (AST) → Mcode (JSON) → Interpret
→ Compile to Mach (planned)
→ Compile to native (planned)
```
Mcode is produced by the `JS_Mcode` compiler pass, which emits a cJSON tree. The mcode interpreter walks this tree directly, dispatching on instruction name strings.
## JSMCode Structure
```c
struct JSMCode {
uint16_t nr_args; // argument count
uint16_t nr_slots; // register count
cJSON **instrs; // pre-flattened instruction array
uint32_t instr_count; // number of instructions
struct {
const char *name; // label name
uint32_t index; // instruction index
} *labels;
uint32_t label_count;
struct JSMCode **functions; // nested functions
uint32_t func_count;
cJSON *json_root; // keeps JSON alive
const char *name; // function name
const char *filename; // source file
uint16_t disruption_pc; // exception handler offset
};
```
## Instruction Format
Each instruction is a JSON array. The first element is the instruction name (string), followed by operands:
```json
["LOADK", 0, 42]
["ADD", 2, 0, 1]
["JMPFALSE", 3, "else_label"]
["CALL", 0, 2, 1]
```
The instruction set mirrors the Mach VM opcodes — same operations, same register semantics, but with string dispatch instead of numeric opcodes.
## Labels
Control flow uses named labels instead of numeric offsets:
```json
["LABEL", "loop_start"]
["ADD", 1, 1, 2]
["JMPFALSE", 3, "loop_end"]
["JMP", "loop_start"]
["LABEL", "loop_end"]
```
Labels are collected into a name-to-index map during loading, enabling O(1) jump resolution.
## Differences from Mach
| Property | Mcode | Mach |
|----------|-------|------|
| Instructions | cJSON arrays | 32-bit binary |
| Dispatch | String comparison | Switch on opcode byte |
| Constants | Inline in JSON | Separate constant pool |
| Jump targets | Named labels | Numeric offsets |
| Memory | Heap (cJSON nodes) | Off-heap (malloc) |
## Purpose
Mcode serves as an inspectable, debuggable intermediate format:
- **Human-readable** — the JSON representation can be printed and examined
- **Language-independent** — any tool that produces the correct JSON can target the ƿit runtime
- **Compilation target** — the Mach compiler can consume mcode as input, and future native code generators can work from the same representation
The cost of string-based dispatch makes mcode slower than the binary Mach VM, so it is primarily useful during development and as a compilation intermediate rather than for production execution.

## Object Header
Every heap-allocated object begins with a 64-bit header word (`objhdr_t`):
```
[capacity: 56 bits][flags: 5 bits][type: 3 bits]
```
### Type Field (bits 0-2)
| Value | Type | Description |
|-------|------|-------------|
| 0 | `OBJ_ARRAY` | Dynamic array of JSValues |
| 1 | `OBJ_BLOB` | Binary data (bits) |
| 2 | `OBJ_TEXT` | Unicode text string |
| 3 | `OBJ_RECORD` | Key-value object with prototype chain |
| 4 | `OBJ_FUNCTION` | Function (C, bytecode, register, or mcode) |
| 5 | `OBJ_CODE` | Compiled bytecode |
| 6 | `OBJ_FRAME` | Stack frame for closures |
| 7 | `OBJ_FORWARD` | Forwarding pointer (GC) |
### Flags (bits 3-7)
- **Bit 3 (S)** — Stone flag. If set, the object is immutable and excluded from GC.
- **Bit 4 (P)** — Properties flag.
- **Bit 5 (A)** — Array flag.
- **Bit 7 (R)** — Reserved.
### Capacity (bits 8-63)
The interpretation of the 56-bit capacity field depends on the object type.
## Array
```c
struct JSArray {
objhdr_t header; // type=0, capacity=element slots
word_t len; // current number of elements
JSValue values[]; // inline flexible array
};
```
Capacity is the number of JSValue slots allocated. Length is the number currently in use. Arrays grow by reallocating with a larger capacity.
## Blob
```c
struct JSBlob {
objhdr_t header; // type=1, capacity=allocated bits
word_t length; // length in bits
uint8_t bits[]; // bit-packed data
};
```
Blobs are bit-addressable. The length field tracks the exact number of bits written. A blob starts as antestone (mutable) for writing, then becomes stone (immutable) for reading.
## Text
```c
struct JSText {
objhdr_t header; // type=2, capacity=character slots
word_t length; // length in codepoints (or hash if stoned)
word_t packed[]; // two UTF-32 chars per 64-bit word
};
```
Text is stored as UTF-32, with two 32-bit codepoints packed per 64-bit word. When a text object is stoned, the length field is repurposed to cache the hash value (computed via `fash64`), since stoned text is immutable and the hash never changes.
## Record
```c
struct JSRecord {
objhdr_t header; // type=3, capacity=hash table slots
JSRecord *proto; // prototype chain pointer
word_t len; // number of entries
slot slots[]; // key-value pairs (hash table)
};
```
Records use a hash table with linear probing. Slot 0 is reserved for internal metadata (class ID and record ID). Empty slots use `JS_NULL` as the key; deleted slots use `JS_EXCEPTION` as a tombstone.
The prototype chain is a linked list of JSRecord pointers, traversed during property lookup.
## Function
```c
struct JSFunction {
objhdr_t header; // type=4
JSValue name; // function name
int16_t length; // arity (-1 for variadic)
uint8_t kind; // C, bytecode, register, or mcode
union {
struct { ... } cfunc; // C function pointer
struct { ... } bytecode; // bytecode + frame
struct { ... } regvm; // register VM code
struct { ... } mcode; // mcode IR
} u;
};
```
The kind field selects which union variant is active. Functions can be implemented in C (native), bytecode (stack VM), register code (mach VM), or mcode (JSON interpreter).
## Frame
```c
struct JSFrame {
objhdr_t header; // type=6, capacity=slot count
JSValue function; // owning function
JSValue caller; // parent frame
uint32_t return_pc; // return address
JSValue slots[]; // [this][args][captured][locals][temps]
};
```
Frames capture the execution context for closures. The slots array contains the function's `this` binding, arguments, captured upvalues, local variables, and temporaries. Frames are linked via the caller field for upvalue resolution across closure depth.
## Forwarding Pointer
```
[pointer: 61 bits][111]
```
During garbage collection, when an object is copied to the new heap, the old header is replaced with a forwarding pointer to the new location. This is type 7 (`OBJ_FORWARD`) and stores the new address in bits 3-63. See [Garbage Collection](#gc) for details.
## Object Sizing
All objects are aligned to 8 bytes. The total size in bytes for each type:
| Type | Size |
|------|------|
| Array | `8 + 8 + capacity * 8` |
| Blob | `8 + 8 + ceil(capacity / 8)` |
| Text | `8 + 8 + ceil(capacity / 2) * 8` |
| Record | `8 + 8 + 8 + (capacity + 1) * 16` |
| Function | `sizeof(JSFunction)` (fixed) |
| Code | `sizeof(JSFunctionBytecode)` (fixed) |
| Frame | `8 + 8 + 8 + 4 + capacity * 8` |

title: "Stone Memory"
description: "Immutable arena allocation"
---
## Overview
Stone memory is a separate allocation arena for immutable values. Objects in stone memory are permanent — they are never moved, never freed, and never touched by the garbage collector.
The `stone()` function in ƿit petrifies a value, deeply freezing it and all its descendants. Stoned objects have the S bit set in their object header.
## The Stone Arena
Stone memory uses bump allocation from a contiguous arena:
```
stone_base ──────── stone_free ──────── stone_end
[allocated objects] [free space ]
```
Allocation advances `stone_free` forward. When the arena is exhausted, overflow pages are allocated via the system allocator and linked together:
```c
struct StonePage {
struct StonePage *next;
size_t size;
uint8_t data[];
};
```
## The S Bit
Bit 3 of the object header is the stone flag. When set:
- The object is **immutable** — writes disrupt
- The object is **excluded from GC** — the collector skips it entirely
- For text objects, the length field caches the **hash** instead of the character count (since the text cannot change, the hash is computed once and reused)
## What Gets Stoned
When `stone(value)` is called:
1. If the value is already stone, return immediately
2. Recursively walk all nested values (array elements, record fields, etc.)
3. Copy each mutable object into the stone arena
4. Set the S bit on each copied object
5. Return the stoned value
The operation is deep — an entire object graph becomes permanently immutable.
## Text Interning
The stone arena maintains a hash table for text interning. When a text value is stoned, it is looked up in the intern table. If an identical string already exists in stone memory, the existing one is reused. This deduplicates strings and makes equality comparison O(1) for stoned text.
The hash is computed with `fash64` over the packed UTF-32 words.
## Usage Patterns
### Module Return Values
Every module's return value is automatically stoned:
```javascript
// config.cm
return {
debug: true,
timeout: 30
}
// The returned object is stone — shared safely between actors
```
### Message Passing
Messages between actors are stoned before delivery, ensuring actors never share mutable state.
### Constants
Literal objects and arrays that can be determined at compile time may be allocated directly in stone memory.
## Relationship to GC
The Cheney copying collector only operates on the mutable heap. During collection, when the collector encounters a pointer to stone memory (S bit set), it skips it — stone objects are roots that never move. This means stone memory acts as a permanent root set with zero GC overhead.

title: "Value Representation"
description: "JSValue tagging and encoding"
---
## Overview
Every value in ƿit is a 64-bit word called a JSValue. The runtime uses LSB (least significant bit) tagging to pack type information directly into the value, avoiding heap allocation for common types.
## Tag Encoding
The lowest bits of a JSValue determine its type:
| LSB Pattern | Type | Payload |
|-------------|------|---------|
| `xxxxxxx0` | Integer | 31-bit signed integer in upper bits |
| `xxxxx001` | Pointer | 61-bit aligned heap pointer |
| `xxxxx101` | Short float | 8-bit exponent + 52-bit mantissa |
| `xxxxx011` | Special | 5-bit tag selects subtype |
### Integers
If the least significant bit is 0, the value is an immediate 31-bit signed integer. The integer is stored in the upper bits, extracted via `v >> 1`.
```
[integer: 31 bits][0]
```
Range: -1073741824 to 1073741823. Numbers outside this range are stored as short floats or heap-allocated.
### Pointers
If the lowest 3 bits are `001`, the value is a pointer to a heap object. The pointer is 8-byte aligned, so the low 3 bits are available for the tag. The actual address is extracted by clearing the low 3 bits.
```
[pointer: 61 bits][001]
```
All heap objects (arrays, records, blobs, text, functions, etc.) are referenced through pointer-tagged JSValues.
### Short Floats
If the lowest 3 bits are `101`, the value encodes a floating-point number directly. The format uses an 8-bit exponent (bias 127) and 52-bit mantissa, similar to IEEE 754 but with reduced range.
```
[sign: 1][exponent: 8][mantissa: 52][101]
```
Range: approximately ±3.4 * 10^38. Numbers outside this range fall back to null. Zero is always positive zero.
### Specials
If the lowest 2 bits are `11`, the next 3 bits select a special type:
| 5-bit Tag | Value |
|-----------|-------|
| `00011` | Boolean (true/false in upper bits) |
| `00111` | Null |
| `01111` | Exception marker |
| `10111` | Uninitialized |
| `11011` | Immediate string |
| `11111` | Catch offset |
## Immediate Strings
Short ASCII strings (up to 7 characters) are packed directly into the JSValue without heap allocation:
```
[char6][char5][char4][char3][char2][char1][char0][length: 3][11011]
```
Each character occupies 8 bits. The length (0-7) is stored in bits 5-7. Only ASCII characters (0-127) qualify — any non-ASCII character forces heap allocation.
```javascript
var s = "hello" // 5 chars, fits in immediate string
var t = "" // immediate (length 0)
var u = "longtext" // 8 chars, heap-allocated
```
## Null
Null is encoded as a special-tagged value with tag `00111`. There is no `undefined` in ƿit — only null.
```javascript
var x = null // special tag null
var y = 1 / 0 // also null (division by zero)
var z = {}.missing // null (missing field)
```
## Boolean
True and false are encoded as specials with tag `00011`, distinguished by a bit in the upper payload.
## Summary
The tagging scheme ensures that the most common values — small integers, booleans, null, and short strings — require zero heap allocation. This significantly reduces GC pressure and improves cache locality.

title: "Wota Format"
description: "Word Object Transfer Arrangement"
weight: 86
type: "docs"
---
Wota is a binary message format for local inter-process communication. It is similar to Nota but works at word granularity (64-bit words) rather than byte granularity. Wota arrangements are less compact than Nota but faster to arrange and consume.
Wota stands for Word Object Transfer Arrangement.
## Type Summary
| Byte | Type |
|------|------|
| `00` | Integer |
| `01` | Floating Point |
| `02` | Array |
| `03` | Record |
| `04` | Blob |
| `05` | Text |
| `07` | Symbol |
## Preambles
Every Wota value starts with a preamble word. The least significant byte contains the type. The remaining 56 bits contain type-specific data.
## Blob
A blob is a string of bits. The remaining field contains the number of bits. The number of words that follow: `floor((number_of_bits + 63) / 64)`. The first bit of the blob goes into the most significant bit of the first word. The final word is padded with 0.
Example: A blob containing 25 bits `111100001110001100100001`:
```
0000000000001904 # preamble: 25 bits, type blob
F0E3208000000000 # data (padded to 64 bits)
```
## Text
The text is a string of UTF-32 characters packed 2 per word. The remaining field contains the number of characters. The number of words that follow: `floor((number_of_characters + 1) / 2)`. The final word is padded with 0.
Example: `"cat"`:
```
0000000000000305 # preamble: 3 characters, type text
0000006300000061 # 'c' and 'a'
0000007400000000 # 't' and padding
```
## Array
An array is an ordered sequence of values. The remaining field contains the number of elements. Following the preamble are the elements, each beginning with its own preamble. Nesting is encouraged. Cyclic structures are not allowed.
Example: `["duck", "dragon"]`:
```
0000000000000202 # preamble: 2 elements, type array
0000000000000405 # text "duck": 4 chars
0000006400000074 # 'd' 't' (reversed pair order)
000000630000006B # 'c' 'k'
0000000000000605 # text "dragon": 6 chars
0000006400000072 # 'd' 'r'
0000006100000067 # 'a' 'g'
0000006F0000006E # 'o' 'n'
```
## Record
A record is a set of key/value pairs. Keys must be text. The remaining field contains the number of pairs.
Example: `{"ox": ["O", "X"]}`:
```
0000000000000103 # preamble: 1 pair, type record
0000000000000205 # key "ox": 2 chars
0000006F00000078 # 'o' 'x'
0000000000000202 # value: array of 2
0000000000000105 # "O": 1 char
0000004F00000000 # 'O'
0000000000000105 # "X": 1 char
0000005800000000 # 'X'
```
## Number
Numbers are represented as DEC64. To arrange an integer, shift the integer up 8 bits. The number is incorporated directly into the preamble.
Example: `7`:
```
0000000000000700 # integer 7 as DEC64
```
To arrange a floating point number, place the number in the word following the floating point preamble.
Example: `4.25`:
```
0000000000000001 # preamble: type floating point
000000000001A9FE # DEC64 encoding of 4.25
```
Care must be taken when decoding that the least significant byte of the number is not `80` (the null exponent).
## Symbol
The remaining field contains the symbol.
Example: `[null, false, true, private, system]`:
```
0000000000000502 # array of 5
0000000000000007 # null
0000000000000207 # false
0000000000000307 # true
0000000000000807 # private
0000000000000907 # system
```

# Plan: Complete Copying GC Implementation
## Overview
Remove reference counting (DupValue/FreeValue) entirely and complete the Cheney copying garbage collector. Each JSContext will use bump allocation from a heap block, and when out of memory, request a new heap from JSRuntime's buddy allocator and copy live objects to the new heap.
## Target Architecture (from docs/memory.md)
### Object Types (simplified from current):
**Type 0 - Array**: `{ header, length, elements[] }`
**Type 1 - Blob**: `{ header, length, bits[] }`
**Type 2 - Text**: `{ header, length_or_hash, packed_chars[] }`
**Type 3 - Record**: `{ header, prototype, length, key_value_pairs[] }`
**Type 4 - Function**: `{ header, code_ptr, outer_frame_ptr }` - 3 words only, always stone
**Type 5 - Frame**: `{ header, function_ptr, caller_ptr, ret_addr, args[], closure_vars[], local_vars[], temps[] }`
**Type 6 - Code**: Lives in immutable memory only, never copied
**Type 7 - Forward**: Object has moved; cap56 contains new address
### Key Design Points:
- **JSFunction** is just a pointer to code and a pointer to the frame that created it (3 words)
- **Closure variables live in frames** - when a function returns, its frame is "reduced" to just the closure variables
- **Code objects are immutable** - stored in stone memory, never copied during GC
- **Frame reduction**: When a function returns, `caller` is set to zero, signaling the frame can be shrunk
## Current State (needs refactoring)
1. **Partial Cheney GC exists** at `source/quickjs.c:1844-2030`: `ctx_gc`, `gc_copy_value`, `gc_scan_object`
2. **744 calls to JS_DupValue/JS_FreeValue** scattered throughout (currently undefined, causing compilation errors)
3. **Current JSFunction** is bloated (has kind, name, union of cfunc/bytecode/bound) - needs simplification
4. **Current JSVarRef** is a separate object - should be eliminated, closures live in frames
5. **Bump allocator** in `js_malloc` (line 1495) with `heap_base`/`heap_free`/`heap_end`
6. **Buddy allocator** for memory blocks (lines 1727-1837)
7. **Header offset inconsistency** - some structs have header at offset 0, some at offset 8
## Implementation Steps
### Phase 1: Define No-Op DupValue/FreeValue (To Enable Compilation)
Add these near line 100 in `source/quickjs.c`:
```c
/* Copying GC - no reference counting needed */
#define JS_DupValue(ctx, v) (v)
#define JS_FreeValue(ctx, v) ((void)0)
#define JS_DupValueRT(rt, v) (v)
#define JS_FreeValueRT(rt, v) ((void)0)
```
This makes the code compile while keeping existing call sites (they become no-ops).
### Phase 2: Standardize Object Headers (offset 0)
Remove `JSGCObjectHeader` (ref counting remnant) and put `objhdr_t` at offset 0:
```c
typedef struct JSArray {
objhdr_t hdr; // offset 0
word_t length;
JSValue values[];
} JSArray;
typedef struct JSRecord {
objhdr_t hdr; // offset 0
JSRecord *proto;
word_t length;
slot slots[];
} JSRecord;
typedef struct JSText {
objhdr_t hdr; // offset 0
word_t length; // pretext: length, text: hash
word_t packed[];
} JSText;
typedef struct JSBlob {
objhdr_t hdr; // offset 0
word_t length;
uint8_t bits[];
} JSBlob;
/* Simplified JSFunction per memory.md - 3 words */
typedef struct JSFunction {
objhdr_t hdr; // offset 0, always stone
JSCode *code; // pointer to immutable code object
struct JSFrame *outer; // frame that created this function
} JSFunction;
/* JSFrame per memory.md */
typedef struct JSFrame {
objhdr_t hdr; // offset 0
JSFunction *function; // function being executed
struct JSFrame *caller; // calling frame (NULL = reduced/returned)
word_t ret_addr; // return instruction address
JSValue slots[]; // args, closure vars, locals, temps
} JSFrame;
/* JSCode - always in immutable (stone) memory */
typedef struct JSCode {
objhdr_t hdr; // offset 0, always stone
word_t arity; // max number of inputs
word_t frame_size; // capacity of activation frame
word_t closure_size; // reduced capacity for returned frames
word_t entry_point; // address to begin execution
word_t disruption_point;// address of disruption clause
uint8_t bytecode[]; // actual bytecode
} JSCode;
```
### Phase 3: Complete gc_object_size for All Types
Update `gc_object_size` (line 1850) to read header at offset 0:
```c
static size_t gc_object_size(void *ptr) {
objhdr_t hdr = *(objhdr_t*)ptr; // Header at offset 0
uint8_t type = objhdr_type(hdr);
uint64_t cap = objhdr_cap56(hdr);
switch (type) {
case OBJ_ARRAY:
return sizeof(JSArray) + cap * sizeof(JSValue);
case OBJ_BLOB:
return sizeof(JSBlob) + (cap + 7) / 8; // cap is bits
case OBJ_TEXT:
return sizeof(JSText) + ((cap + 1) / 2) * sizeof(uint64_t);
case OBJ_RECORD:
return sizeof(JSRecord) + (cap + 1) * sizeof(slot); // cap is mask
case OBJ_FUNCTION:
return sizeof(JSFunction); // 3 words
case OBJ_FRAME:
return sizeof(JSFrame) + cap * sizeof(JSValue); // cap is slot count
case OBJ_CODE:
return 0; // Code is never copied (immutable)
default:
return 64; // Conservative fallback
}
}
```
### Phase 4: Complete gc_scan_object for All Types
Update `gc_scan_object` (line 1924):
```c
static void gc_scan_object(JSContext *ctx, void *ptr, uint8_t **to_free, uint8_t *to_end) {
objhdr_t hdr = *(objhdr_t*)ptr;
uint8_t type = objhdr_type(hdr);
switch (type) {
case OBJ_ARRAY: {
JSArray *arr = (JSArray*)ptr;
for (uint32_t i = 0; i < arr->length; i++) {
arr->values[i] = gc_copy_value(ctx, arr->values[i], to_free, to_end);
}
break;
}
case OBJ_RECORD: {
JSRecord *rec = (JSRecord*)ptr;
// Copy prototype
if (rec->proto) {
JSValue proto_val = JS_MKPTR(rec->proto);
proto_val = gc_copy_value(ctx, proto_val, to_free, to_end);
rec->proto = (JSRecord*)JS_VALUE_GET_PTR(proto_val);
}
// Copy table entries
uint32_t mask = objhdr_cap56(rec->hdr);
for (uint32_t i = 1; i <= mask; i++) { // Skip slot 0
JSValue k = rec->slots[i].key;
if (!rec_key_is_empty(k) && !rec_key_is_tomb(k)) {
rec->slots[i].key = gc_copy_value(ctx, k, to_free, to_end);
rec->slots[i].value = gc_copy_value(ctx, rec->slots[i].value, to_free, to_end);
}
}
break;
}
case OBJ_FUNCTION: {
JSFunction *func = (JSFunction*)ptr;
// Code is immutable, don't copy - but outer frame needs copying
if (func->outer) {
JSValue outer_val = JS_MKPTR(func->outer);
outer_val = gc_copy_value(ctx, outer_val, to_free, to_end);
func->outer = (JSFrame*)JS_VALUE_GET_PTR(outer_val);
}
break;
}
case OBJ_FRAME: {
JSFrame *frame = (JSFrame*)ptr;
// Copy function pointer
if (frame->function) {
JSValue func_val = JS_MKPTR(frame->function);
func_val = gc_copy_value(ctx, func_val, to_free, to_end);
frame->function = (JSFunction*)JS_VALUE_GET_PTR(func_val);
}
// Copy caller (unless NULL = reduced frame)
if (frame->caller) {
JSValue caller_val = JS_MKPTR(frame->caller);
caller_val = gc_copy_value(ctx, caller_val, to_free, to_end);
frame->caller = (JSFrame*)JS_VALUE_GET_PTR(caller_val);
}
// Copy all slots (args, closure vars, locals, temps)
uint32_t slot_count = objhdr_cap56(frame->hdr);
for (uint32_t i = 0; i < slot_count; i++) {
frame->slots[i] = gc_copy_value(ctx, frame->slots[i], to_free, to_end);
}
break;
}
case OBJ_TEXT:
case OBJ_BLOB:
case OBJ_CODE:
// No internal references to scan
break;
}
}
```
### Phase 5: Fix gc_copy_value Forwarding
Update `gc_copy_value` (line 1883) for offset 0 headers:
```c
static JSValue gc_copy_value(JSContext *ctx, JSValue v, uint8_t **to_free, uint8_t *to_end) {
if (!JS_IsPtr(v)) return v; // Immediate value
void *ptr = JS_VALUE_GET_PTR(v);
// Stone memory - don't copy (includes Code objects)
objhdr_t hdr = *(objhdr_t*)ptr;
if (objhdr_s(hdr)) return v;
// Check if in current heap
if ((uint8_t*)ptr < ctx->heap_base || (uint8_t*)ptr >= ctx->heap_end)
return v; // External allocation
// Already forwarded?
if (objhdr_type(hdr) == OBJ_FORWARD) {
void *new_ptr = (void*)(uintptr_t)objhdr_cap56(hdr);
return JS_MKPTR(new_ptr);
}
// Copy object to new space
size_t size = gc_object_size(ptr);
void *new_ptr = *to_free;
*to_free += size;
memcpy(new_ptr, ptr, size);
// Leave forwarding pointer in old location
*(objhdr_t*)ptr = objhdr_make((uint64_t)(uintptr_t)new_ptr, OBJ_FORWARD, 0, 0, 0, 0);
return JS_MKPTR(new_ptr);
}
```
### Phase 6: Complete GC Root Tracing
Update `ctx_gc` (line 1966) to trace all roots including JSGCRef:
```c
static int ctx_gc(JSContext *ctx) {
// ... existing setup code ...
// Copy roots: global object, class prototypes, etc. (existing)
ctx->global_obj = gc_copy_value(ctx, ctx->global_obj, &to_free, to_end);
ctx->global_var_obj = gc_copy_value(ctx, ctx->global_var_obj, &to_free, to_end);
// ... other existing root copying ...
// Copy GC root stack (JS_PUSH_VALUE/JS_POP_VALUE)
for (JSGCRef *ref = ctx->top_gc_ref; ref; ref = ref->prev) {
ref->val = gc_copy_value(ctx, ref->val, &to_free, to_end);
}
// Copy GC root list (JS_AddGCRef/JS_DeleteGCRef)
for (JSGCRef *ref = ctx->last_gc_ref; ref; ref = ref->prev) {
ref->val = gc_copy_value(ctx, ref->val, &to_free, to_end);
}
// Copy current exception
ctx->current_exception = gc_copy_value(ctx, ctx->current_exception, &to_free, to_end);
// Cheney scan (existing)
// ...
}
```
### Phase 7: Trigger GC on Allocation Failure
Update `js_malloc` (line 1495):
```c
void *js_malloc(JSContext *ctx, size_t size) {
size = (size + 7) & ~7; // Align to 8 bytes
if ((uint8_t*)ctx->heap_free + size > (uint8_t*)ctx->heap_end) {
if (ctx_gc(ctx) < 0) {
JS_ThrowOutOfMemory(ctx);
return NULL;
}
// Retry after GC
if ((uint8_t*)ctx->heap_free + size > (uint8_t*)ctx->heap_end) {
JS_ThrowOutOfMemory(ctx);
return NULL;
}
}
void *ptr = ctx->heap_free;
ctx->heap_free = (uint8_t*)ctx->heap_free + size;
return ptr;
}
```
### Phase 8: Frame Reduction (for closures)
When a function returns, "reduce" its frame to just closure variables:
```c
static void reduce_frame(JSContext *ctx, JSFrame *frame) {
if (frame->caller == NULL) return; // Already reduced
JSCode *code = frame->function->code;
uint32_t closure_size = code->closure_size;
// Shrink capacity to just closure variables
frame->hdr = objhdr_make(closure_size, OBJ_FRAME, 0, 0, 0, 0);
frame->caller = NULL; // Signal: frame is reduced
}
```
### Phase 9: Remove Unused Reference Counting Code
Delete:
- `gc_decref`, `gc_decref_child` functions
- `gc_scan_incref_child`, `gc_scan_incref_child2` functions
- `JS_GCPhaseEnum`, `gc_phase` fields
- `JSGCObjectHeader` struct (merge into objhdr_t)
- `ref_count` fields from any remaining structs
- `mark_function_children_decref` function
- All `free_*` functions that rely on ref counting
## Files to Modify
1. **source/quickjs.c** - Main implementation:
- Add DupValue/FreeValue no-op macros (~line 100)
- Restructure JSArray, JSBlob, JSText, JSRecord (lines 468-499)
- Simplify JSFunction to 3-word struct (line 1205)
- Add JSFrame as heap object (new)
- Restructure JSCode/JSFunctionBytecode (line 1293)
- Fix gc_object_size (line 1850)
- Fix gc_copy_value (line 1883)
- Complete gc_scan_object (line 1924)
- Update ctx_gc for all roots (line 1966)
- Update js_malloc to trigger GC (line 1495)
- Delete ref counting code throughout
2. **source/quickjs.h** - Public API:
- Remove JSGCObjectHeader
- Update JSValue type checks if needed
- Ensure JS_IsStone works with offset 0 headers
## Execution Order
1. **First**: Add DupValue/FreeValue macros (enables compilation)
2. **Second**: Standardize struct layouts (header at offset 0)
3. **Third**: Fix gc_object_size and gc_copy_value
4. **Fourth**: Complete gc_scan_object for all types
5. **Fifth**: Update ctx_gc with complete root tracing
6. **Sixth**: Wire js_malloc to trigger GC
7. **Seventh**: Add frame reduction for closures
8. **Finally**: Remove ref counting dead code
## Verification
1. **Compile test**: `make` should succeed without errors
2. **Basic test**: Run simple scripts:
```js
var a = [1, 2, 3]
log.console(a[1])
```
3. **Stress test**: Allocate many objects to trigger GC:
```js
for (var i = 0; i < 100000; i++) {
var x = { value: i }
}
log.console("done")
```
4. **Closure test**: Test functions with closures survive GC:
```js
fn make_counter() {
var count = 0
fn inc() { count = count + 1; return count }
return inc
}
var c = make_counter()
log.console(c()) // 1
log.console(c()) // 2
```
5. **GC stress with closures**: Create many closures, trigger GC, verify they still work
## Key Design Decisions (Resolved)
1. **JSCode storage**: Lives in stone (immutable) memory, never copied during GC ✓
2. **Header offset**: Standardized to offset 0 for all heap objects ✓
3. **Closure variables**: Live in JSFrame objects; frames are "reduced" when functions return ✓
4. **JSVarRef**: Eliminated - closures reference their outer frame directly ✓

 The original parseq.js relied on the browser's setTimeout and ran in
 milliseconds. In Misty we may be given an optional @.delay capability
 (arguments[0]) and time limits are expressed in **seconds**. This rewrite
 removes the setTimeout dependency, uses the @.delay capability when it is

# Cell/QuickJS Refactoring Plan: Remove Atoms, Shapes, and Dual-Encoding
## Overview
Refactor `source/quickjs.c` to match `docs/memory.md` specification:
- Remove JSAtom system (171 references → ~41 remaining)
- Remove JSShape system (94 references) ✓
- Remove IC caches (shape-based inline caches) ✓
- Remove `is_wide_char` dual-encoding (18 locations) ✓
- Use JSValue texts directly as property keys
- Reference: `mquickjs.c` shows the target pattern
## Completed Phases
### Phase 1: Remove is_wide_char Remnants ✓
### Phase 2: Remove IC Caches ✓
### Phase 3: Remove JSShape System ✓
### Phase 4: Complete Property Access with JSValue Keys ✓
Completed:
- Removed JS_GC_OBJ_TYPE_JS_OBJECT fallbacks from OP_get_field
- Removed JS_GC_OBJ_TYPE_JS_OBJECT fallbacks from OP_put_field
- Removed JS_GC_OBJ_TYPE_JS_OBJECT fallbacks from OP_define_field
- Created emit_key() function that adds JSValue to cpool and emits index
---
## Phase 5: Convert JSAtom to JSValue Text (IN PROGRESS)
This is the core transformation. All identifier handling moves from atoms to JSValue.
### Completed Items
**Token and Parser Infrastructure:**
- [x] Change JSToken.u.ident.atom to JSToken.u.ident.str (JSValue)
- [x] Change parse_ident() to return JSValue
- [x] Create emit_key() function (cpool-based)
- [x] Create JS_KEY_* macros for common names (lines ~279-335 in quickjs.c)
- [x] Update all token.u.ident.atom references to .str
- [x] Create keyword lookup table (js_keywords[]) with string comparison
- [x] Rewrite update_token_ident() to use js_keyword_lookup()
- [x] Rewrite is_strict_future_keyword() to use JSValue
- [x] Update token_is_pseudo_keyword() to use JSValue and js_key_equal()
**Function Declaration Parsing:**
- [x] Update js_parse_function_decl() signature to use JSValue func_name
- [x] Update js_parse_function_decl2() to use JSValue func_name throughout
- [x] Update js_parse_function_check_names() to use JSValue
- [x] Convert JS_DupAtom/JS_FreeAtom to JS_DupValue/JS_FreeValue in function parsing
**Variable Definition and Lookup:**
- [x] Update find_global_var() to use JSValue and js_key_equal()
- [x] Update find_lexical_global_var() to use JSValue
- [x] Update find_lexical_decl() to use JSValue and js_key_equal()
- [x] Update js_define_var() to use JSValue
- [x] Update js_parse_check_duplicate_parameter() to use JSValue and js_key_equal()
- [x] Update js_parse_destructuring_var() to return JSValue
- [x] Update js_parse_var() to use JSValue for variable names
**Comparison Helpers:**
- [x] Create js_key_equal_str() for comparing JSValue with C string literals
- [x] Update is_var_in_arg_scope() to use js_key_equal/js_key_equal_str
- [x] Update has_with_scope() to use js_key_equal_str
- [x] Update closure variable comparisons (cv->var_name) to use js_key_equal_str
**Property Access:**
- [x] Fix JS_GetPropertyStr to create proper JSValue keys
- [x] Fix JS_SetPropertyInternal callers to use JS_KEY_* instead of JS_ATOM_*
### JS_KEY_* Macros Added
Compile-time immediate ASCII string constants (≤7 chars):
```c
JS_KEY_empty, JS_KEY_name, JS_KEY_message, JS_KEY_stack,
JS_KEY_errors, JS_KEY_Error, JS_KEY_cause, JS_KEY_length,
JS_KEY_value, JS_KEY_get, JS_KEY_set, JS_KEY_raw,

JS_KEY_var, JS_KEY_new, JS_KEY_of, JS_KEY_yield,
JS_KEY_async, JS_KEY_target, JS_KEY_from, JS_KEY_meta,
JS_KEY_as, JS_KEY_with
```
Runtime macro for strings >7 chars:
```c
#define JS_KEY_STR(ctx, str) JS_NewStringLen((ctx), (str), sizeof(str) - 1)
```
Helper function for comparing JSValue with C string literals:
```c

- JS_ATOM_NULL, JS_ATOM_END - bytecode format markers
- JS_FreeAtom, JS_DupAtom - no-op stubs
- JS_FreeAtomRT, JS_DupAtomRT - no-op stubs
- Legacy BC reader (idx_to_atom array) - for reading old bytecode
---
## Current Build Status
**Build: SUCCEEDS** with warnings (unused variables, labels)
**Statistics:**
- JS_ATOM_* usages: Minimal (only BC serialization compat)
- Property access uses JS_KEY_* macros or JS_GetPropertyStr
- BC_VERSION: 6 (updated for new key-based format)
**What Works:**
- All property access via JSValue keys
- Keyword detection via string comparison
- Function declaration parsing with JSValue names
- Variable definition with JSValue names
- Closure variable tracking with JSValue names
- VM opcode handlers read cpool indices and look up JSValue
- resolve_scope_var() uses JSValue throughout
- js_parse_property_name() returns JSValue
- Bytecode serialization uses bc_put_key/bc_get_key for property keys
- Variable opcodes use key format (cpool indices)
- JSON parsing uses JSValue keys
- Internal variable names use JS_KEY__ret_, JS_KEY__eval_, JS_KEY__var_
- JS_SetPropertyFunctionList uses JSValue keys
- JS_Invoke uses JSValue method keys
- break/continue labels use JSValue
---
## Phase 8: Migrate to New Tagging System (IN PROGRESS)
**Problem**: `JS_VALUE_GET_TAG` returns `JS_TAG_PTR` for all pointers, but ~200 places check for obsolete tags like `JS_TAG_OBJECT`, `JS_TAG_STRING`, `JS_TAG_FUNCTION`, etc., which are never returned. This causes crashes.
**Target Design** (from memory.md):
- JSValue tags: Only `JS_TAG_INT`, `JS_TAG_PTR`, `JS_TAG_SHORT_FLOAT`, `JS_TAG_SPECIAL`
- Pointer types determined by `objhdr_t` header at offset 8 in heap objects
- mist_obj_type: `OBJ_ARRAY(0)`, `OBJ_BLOB(1)`, `OBJ_TEXT(2)`, `OBJ_RECORD(3)`, `OBJ_FUNCTION(4)`, etc.
### 8.1 Unified Heap Object Layout ✓
- [x] Updated mist_text structure to have objhdr_t at offset 8:
```c
typedef struct mist_text {
JSRefCountHeader _dummy_header; /* unused, for offset alignment */
uint32_t _pad; /* padding to align objhdr_t to offset 8 */
objhdr_t hdr; /* NOW at offset 8, like JSString */
word_t length;
word_t packed[];
} mist_text;
```
- [x] JSString already has objhdr_t at offset 8
### 8.2 Type-Checking Helper Functions ✓
Added lowercase internal helpers (to avoid conflict with quickjs.h declarations):
```c
static inline JS_BOOL js_is_gc_object(JSValue v) { return JS_IsPtr(v); }
static inline JSGCObjectTypeEnum js_get_gc_type(JSValue v) {
return ((JSGCObjectHeader *)JS_VALUE_GET_PTR(v))->gc_obj_type;
}
static inline JS_BOOL js_is_record(JSValue v) {
if (!JS_IsPtr(v)) return FALSE;
return js_get_gc_type(v) == JS_GC_OBJ_TYPE_RECORD;
}
static inline JS_BOOL js_is_array(JSValue v) {
if (!JS_IsPtr(v)) return FALSE;
return js_get_gc_type(v) == JS_GC_OBJ_TYPE_ARRAY;
}
static inline JS_BOOL js_is_function(JSValue v) {
if (!JS_IsPtr(v)) return FALSE;
return js_get_gc_type(v) == JS_GC_OBJ_TYPE_FUNCTION;
}
static inline JS_BOOL js_is_object(JSValue v) {
if (!JS_IsPtr(v)) return FALSE;
JSGCObjectTypeEnum t = js_get_gc_type(v);
return t == JS_GC_OBJ_TYPE_RECORD || t == JS_GC_OBJ_TYPE_ARRAY;
}
```
### 8.3 Updated Core Functions ✓
- [x] Updated JS_IsString to read objhdr_t from offset 8
- [x] Updated js_key_hash to read objhdr_t from offset 8
- [x] Updated js_key_equal to read objhdr_t from offset 8
- [x] Updated __JS_FreeValueRT to use objhdr_type for type dispatch
- [x] Updated JS_MarkValue, JS_MarkValueEdgeEx for GC
- [x] Added JS_SetPropertyValue function
- [x] Changed quickjs.h JS_IsFunction/JS_IsObject from inline to extern declarations
### 8.4 Tag Check Migration (PARTIAL)
Updated some critical tag checks:
- [x] Some JS_TAG_OBJECT checks → js_is_object() or js_is_record()
- [ ] Many more JS_TAG_OBJECT checks remain (~200 total)
- [ ] JS_TAG_FUNCTION checks → js_is_function()
- [ ] JS_TAG_STRING checks (some already use JS_IsString)
### 8.5 Remaining Work
- [ ] Fix ASAN memory corruption error (attempting free on address not malloc'd)
- Crash occurs in js_def_realloc during js_realloc_array
- Address is 112 bytes inside a JSFunctionDef allocation
- [ ] Complete remaining ~200 tag check migrations
- [ ] Add mist_hdr to JSFunction (optional, gc_obj_type already works)
- [ ] Remove obsolete tag definitions from quickjs.h:
- JS_TAG_STRING = -8
- JS_TAG_ARRAY = -6
- JS_TAG_FUNCTION = -5
- JS_TAG_FUNCTION_BYTECODE = -2
- JS_TAG_OBJECT = -1
### Current Status
**Build: SUCCEEDS** with warnings
**Runtime: CRASHES** with ASAN error:
```
==16122==ERROR: AddressSanitizer: attempting free on address which was not malloc()-ed
```
The crash occurs during test execution in `js_def_realloc` called from `js_realloc_array`.
Root cause not yet identified - likely a pointer being passed to realloc that wasn't allocated with malloc.
---
## Notes
- JSVarDef.var_name is JSValue
- JSClosureVar.var_name is JSValue
- JSGlobalVar.var_name is JSValue
- JSFunctionDef.func_name is JSValue
- BlockEnv.label_name is JSValue
- OP_get_field/put_field/define_field already use cpool index format
- JSRecord with open addressing is fully implemented
- js_key_hash and js_key_equal work with both immediate and heap text
- js_key_equal_str enables comparison with C string literals for internal names
