# AI Agent Notes
|
||||
|
||||
## Canonical AI References
|
||||
- Use `docs/ai_language_reference.md` as the primary, compiler-verified Lyng language reference for code generation.
|
||||
- For generics-heavy code generation, follow `docs/ai_language_reference.md` section `7.1 Generics Runtime Model and Bounds` and `7.2 Differences vs Java / Kotlin / Scala`.
|
||||
- Use `docs/ai_stdlib_reference.md` for default runtime/module APIs and stdlib surface.
|
||||
- Treat `LYNG_AI_SPEC.md` and older docs as secondary if they conflict with the two files above.
|
||||
- Prefer the shortest clear loop: use `for` for straightforward iteration/ranges; use `while` only when loop state/condition is irregular or changes in ways `for` cannot express cleanly.
|
||||
- In Lyng code, slice strings with range indexing (`text[a..<b]`, `text[..<n]`, `text[n..]`) and avoid Java/Kotlin-style `substring(...)`.
|
||||
|
||||
## Lyng-First API Declarations
|
||||
- Use `.lyng` declarations as the single source of truth for Lyng-facing API docs and types (especially module extern declarations).
|
||||
- Prefer defining Lyng entities (enums/classes/type shapes) in `.lyng` files; only define them in Kotlin when there is Kotlin/platform-specific implementation detail that cannot be expressed in Lyng.
|
||||
- Avoid hardcoding Lyng API documentation in Kotlin registrars when it can be declared in `.lyng`; Kotlin-side docs should be fallback/bridge only.
|
||||
- For mixed pluggable modules (Lyng + Kotlin), embed module `.lyng` sources as generated Kotlin string literals, evaluate them into module scope during registration, then attach Kotlin implementations/bindings.
|
||||
|
||||
## Kotlin/Wasm generation guardrails
|
||||
- Avoid creating suspend lambdas for compiler runtime statements. Prefer explicit `object : Statement()` with `override suspend fun execute(...)`.
|
||||
- Do not use `statement { ... }` or other inline suspend lambdas in compiler hot paths (e.g., parsing/var declarations, initializer thunks).
|
||||
- If you need a wrapper for delegated properties, check for `getValue` explicitly and return a concrete `Statement` object when missing; avoid `onNotFoundResult` lambdas.
|
||||
- If wasmJs browser tests hang, first run `:lynglib:wasmJsNodeTest` and look for wasm compilation errors; hangs usually mean module instantiation failed.
|
||||
- Do not increase test timeouts to mask wasm generation errors; fix the invalid IR instead.
|
||||
|
||||
## Type inference notes (notes/new_lyng_type_system_spec.md)
|
||||
- Nullability is Kotlin-style: `T` non-null, `T?` nullable, `!!` asserts non-null.
|
||||
- `void` is a singleton of class `Void` (syntax sugar for return type).
|
||||
- Object members are always allowed even on unknown types; non-Object members require explicit casts. Remove `inspect` from Object and use `toInspectString()` instead.
|
||||
- Type expression checks: `x is T` is value instance check; `T1 is T2` is type-subset; `A in T` means `A` is subset of `T`; `==` is structural type equality.
|
||||
- Type aliases: `type Name = TypeExpr` (generic allowed) expand to their underlying type expressions; no nominal distinctness.
|
||||
- Bounds and variance: `T: A & B` / `T: A | B` for bounds; declaration-site variance with `out` / `in`.
|
||||
- Do not reintroduce bytecode fallback opcodes (e.g., `GET_NAME`, `EVAL_*`, `CALL_FALLBACK`) or runtime name-resolution fallbacks; all symbol resolution must stay compile-time only.
|
||||
|
||||
## Bytecode frame-first migration plan
|
||||
- Treat frame slots as the only storage for locals/temps by default; avoid pre-creating scope slot mappings for compiled functions.
|
||||
- Create closure references only when a capture is detected; use a direct frame+slot reference (foreign slot ref) instead of scope slots.
|
||||
- Keep Scope as a lazy reflection facade: resolve name -> slot only on demand for Kotlin interop (no eager name mapping on every call).
|
||||
- Avoid PUSH_SCOPE/POP_SCOPE in bytecode for loops/functions unless dynamic name access or Kotlin reflection is requested.
|
||||
|
||||
## ABI proposal notes
|
||||
- Runtime generic metadata for generic extern classes is tracked in `proposals/extern_generic_runtime_abi.md`.
|
||||
- Keep this design `Obj`-centric: do not assume extern-class values are `ObjInstance`; collection must be enabled on `ObjClass`.

## Changelog
|
||||
|
||||
### Language Features
|
||||
- Added `return` statement with local and non-local exit support (`return@label`).
|
||||
- Support for `abstract` classes, methods, and variables.
|
||||
- Introduced `interface` as a synonym for `abstract class`.
|
||||
- Multiple Inheritance (MI) completed and enabled by default (C3 MRO).
|
||||
- Class properties with custom accessors (`get`, `set`).
|
||||
- Restricted setter visibility (`private set`, `protected set`).
|
||||
- Late-initialized `val` fields in classes with `Unset` protection.
|
||||
- Named arguments (`name: value`) and named splats (`...Map`).
|
||||
- Assign-if-null operator `?=`.
|
||||
- Refined `protected` visibility rules and `closed` modifier.
|
||||
- Transient attribute `@Transient` for serialization and equality.
|
||||
- Unified Delegation model for `val`, `var`, and `fun`.
|
||||
- Singleton objects (`object`) and object expressions.
|
||||
|
||||
### Standard Library
|
||||
- Added `with(self, block)` for scoped execution.
|
||||
- Added `clamp()` function and extension.
|
||||
- Improved `Exception` and `StackTraceEntry` reporting.
|
||||
|
||||
### Tooling and IDE
|
||||
- **CLI**: Added `fmt` as a first-class subcommand for code formatting.
|
||||
- **IDEA Plugin**: Lightweight autocompletion (experimental), improved docs, and Grazie integration.
|
||||
- **Highlighters**: Updated TextMate bundle and website highlighters for new syntax.
|
||||
|
||||
### Detailed Changes:
|
||||
### Unreleased
|
||||
|
||||
- Language: Refined `protected` visibility rules
|
||||
- Ancestor classes can now access `protected` members of their descendants, provided the ancestor also defines or inherits a member with the same name (indicating an override of a member known to the ancestor).
|
||||
@ -134,6 +109,16 @@
|
||||
|
||||
- Documentation updated (docs/OOP.md and tutorial quick-start) to reflect MI with active C3 MRO.
|
||||
|
||||
Notes:
|
||||
- Existing single-inheritance code continues to work; resolution reduces to the single base.
|
||||
- If code previously relied on non-deterministic parent set iteration, C3 MRO provides a predictable order; disambiguate explicitly if needed using `this@Type`/casts.

High-density specification for LLMs. Reference this for all Lyng code generation.
|
||||
|
||||
## 1. Core Philosophy & Syntax
|
||||
- **Everything is an Expression**: Blocks, `if`, `when`, `for`, `while`, `do-while` return their last expression (or `void`).
|
||||
- **Static Types + Inference**: Every declaration has a compile-time type (explicit or inferred). Types are Kotlin‑style: non‑null by default, nullable with `?`.
|
||||
- **Loops with `else`**: `for`, `while`, and `do-while` support an optional `else` block.
|
||||
- `else` executes **only if** the loop finishes normally (without a `break`).
|
||||
- `break <value>` exits the loop and sets its return value.

||||

|
||||
3. Result of the last iteration (if loop finished normally and no `else`).
|
||||
4. `void` (if loop body never executed and no `else`).
|
||||
- **Implicit Coroutines**: All functions are coroutines. No `async/await`. Use `launch { ... }` (returns `Deferred`) or `flow { ... }`.
|
||||
- **Functions**: Use `fun` or the short form `fn`. Function declarations are expressions returning a callable.
|
||||
- **Variables**: `val` (read-only), `var` (mutable). Supports late-init `val` in classes (must be assigned in `init` or body).
|
||||
- **Serialization**: Use `@Transient` attribute before `val`/`var` or constructor parameters to exclude them from Lynon/JSON serialization. Transient fields are also ignored during `==` structural equality checks.
|
||||
- **Null Safety**: `?` (nullable type), `?.` (safe access), `?( )` (safe invoke), `?{ }` (safe block invoke), `?[ ]` (safe index), `?:` or `??` (elvis), `?=` (assign-if-null).
|
||||
- **Equality**: `==` (equals), `!=` (not equals), `===` (ref identity), `!==` (ref not identity).
|
||||
- **Comparison**: `<`, `>`, `<=`, `>=`, `<=>` (shuttle/spaceship, returns -1, 0, 1).
|
||||
- **Destructuring**: `val [a, b, rest...] = list`. Supports nested `[a, [b, c]]` and splats.
|
||||
- **Compile-Time Resolution Only**: All names/members must resolve at compile time. No runtime name lookup or fallback opcodes.
|
||||
|
||||
## 2. Object-Oriented Programming (OOP)
|
||||
- **Multiple Inheritance**: Supported with **C3 MRO** (Python-style). Diamond-safe.

|
||||
- **Disambiguation**: `this@Base.member()` or `(obj as Base).member()`. `as` returns a qualified view.
|
||||
- **Abstract/Interface**: `interface` is a synonym for `abstract class`. Both support state and constructors.
|
||||
- **Extensions**: `fun Class.ext()` or `val Class.ext get = ...`. Scope-isolated.
|
||||
- **Member Access**: Object members (`toString`, `toInspectString`, `let`, `also`, `apply`, `run`) are allowed on unknown types; all other members require a statically known receiver type or explicit cast.
|
||||
|
||||
## 2.1 Type System (2026)
|
||||
- **Root Type**: Everything is an `Object` (root of the hierarchy).
|
||||
- **Nullability**: Non-null by default (`T`), nullable with `T?`, `!!` asserts non-null.
|
||||
- **Untyped params**: `fun foo(x)` -> `x: Object`, `fun foo(x?)` -> `x: Object?`.
|
||||
- **Untyped vars**: `var x` is `Unset` until first assignment locks the type (including nullability).
|
||||
- `val x = null` -> type `Null`; `var x = null` -> type `Object?`.
|
||||
- **Inference**:
|
||||
- List literals infer union element types; empty list defaults to `List<Object>` unless constrained.
|
||||
- Map literals infer key/value types; empty map defaults to `Map<Object, Object>` unless constrained.
|
||||
- Mixed numeric ops promote `Int` + `Real` to `Real`.
|
||||
- **Type aliases**: `type Name = TypeExpr` (generic allowed). Aliases expand to their underlying type expressions (no nominal distinctness).
|
||||
- **Generics**: Bounds with `T: A & B` or `T: A | B`; variance uses `out`/`in` (declaration‑site only).
|
||||
- **Casts**: `as` is a runtime-checked cast; `as?` is safe-cast returning `null`. If the value is nullable, `as T` implies `!!`.
|
||||
|
||||
## 2.2 Type Expressions and Checks
|
||||
- **Value checks**: `x is T` (runtime instance check).
|
||||
- **Type checks**: `T1 is T2` and `A in T` are subset checks between type expressions (compile-time where possible).
|
||||
- **Type equality**: `T1 == T2` is structural (unions/intersections are order‑insensitive).
|
||||
- **Compile-time enforcement**: Bounds are checked at call sites; runtime checks only appear when the compile‑time type is too general.
|
||||

||||

||||
|
||||
## 5. Patterns & Shorthands

||||

|
||||
- **Map Literals**: `{ key: value, identifier: }` (identifier shorthand `x:` is `x: x`). Empty map is `Map()`.
|
||||
- **Named Arguments**: `fun(y: 10, x: 5)`. Shorthand: `Point(x:, y:)`.
|
||||
- **Varargs & Splats**: `fun f(args...)`, `f(...otherList)`.
|
||||
- **Labels**: `loop@ for(x in list) { if(x == 0) break@loop }`.
|
||||
- **Dynamic**: `val d = dynamic { get { name -> ... } }` allows `d.anyName` via explicit dynamic handler (not implicit fallback).

# Lyng Bytecode VM Spec v0 (Draft)
|
||||
|
||||
This document describes a register-like (3-address) bytecode for Lyng with
|
||||
dynamic slot width (8/16/32-bit slot IDs), a slot-tail argument model, and
|
||||
typed lanes for Obj/Int/Real/Bool. The VM is intended to run as a suspendable
|
||||
interpreter and fall back to the existing AST execution when needed.
|
||||
|
||||
## 1) Frame & Slot Model
|
||||
|
||||
### Frame metadata
|
||||
- localCount: number of local slots for this function (fixed at compile time).
|
||||
- argCount: number of arguments passed at call time.
|
||||
- scopeSlotNames: optional debug names for scope slots (locals/params), aligned to slot mapping.
|
||||
- argBase = localCount.
|
||||
|
||||
### Slot layout
|
||||
slots[0 .. localCount-1] locals
|
||||
slots[localCount .. localCount+argCount-1] arguments
|
||||
|
||||
### Typed lanes
|
||||
- slotType[]: UNKNOWN/OBJ/INT/REAL/BOOL
|
||||
- objSlots[], intSlots[], realSlots[], boolSlots[]
|
||||
- A slot is a logical index; active lane is selected by slotType.
|
||||
|
||||
### Parameter access
|
||||
- param i => slot localCount + i
|
||||
- variadic extra => slot localCount + declaredParamCount + k
|
||||
|
||||
### Debug metadata (optional)
|
||||
- scopeSlotNames: array sized scopeSlotCount, each entry nullable.
|
||||
- Intended for disassembly/debug tooling; VM semantics do not depend on it.
|
||||
|
||||
### Constant pool extras
|
||||
- SlotPlan: map of name -> slot index, used by PUSH_SCOPE to pre-allocate and map loop locals.
|
||||
- CallArgsPlan: ordered argument specs (name/splat) + tailBlock flag, used when argCount has the plan flag set.
|
||||
|
||||
## 2) Slot ID Width
|
||||
|
||||
Per frame, select:
|
||||
- 8-bit if localCount + argCount < 256
|
||||
- 16-bit if < 65536
|
||||
- 32-bit otherwise
|
||||
|
||||
The decoder uses a dedicated loop per width. All slot operands are expanded to
|
||||
Int internally.
|
||||
|
||||
## 3) CALL Semantics (Model A)
|
||||
|
||||
Instruction:
|
||||
CALL_DIRECT fnId, argBase, argCount, dst
|
||||
|
||||
Behavior:
|
||||
- Allocate a callee frame sized localCount + argCount.
|
||||
- Copy caller slots [argBase .. argBase+argCount-1] into callee slots
|
||||
[localCount .. localCount+argCount-1].
|
||||
- Callee returns via RET slot or RET_VOID.
|
||||
- Caller stores return value to dst.
|
||||
|
||||
Other calls:
|
||||
- CALL_VIRTUAL recvSlot, methodId, argBase, argCount, dst
|
||||
- CALL_FALLBACK stmtId, argBase, argCount, dst
|
||||
- CALL_SLOT calleeSlot, argBase, argCount, dst
|
||||
|
||||
## 4) Binary Encoding Layout
|
||||
|
||||
All instructions are:
|
||||
[opcode:U8] [operands...]
|
||||
|
||||
Operand widths:
|
||||
- slotId: S = 1/2/4 bytes (per frame slot width)
|
||||
- constId: K = 2 bytes (U16), extend to 4 if needed
|
||||
- ip: I = 2 bytes (U16) or 4 bytes (U32) per function size
|
||||
- fnId/methodId/stmtId: F/M/T = 2 bytes (U16) unless extended
|
||||
- argCount: C = 2 bytes (U16), extend to 4 if needed
|
||||
|
||||
Endianness: little-endian for multi-byte operands.
|
||||
|
||||
Common operand patterns:
|
||||
- S: one slot
|
||||
- SS: two slots
|
||||
- SSS: three slots
|
||||
- K S: constId + dst slot
|
||||
- S I: slot + jump target
|
||||
- I: jump target
|
||||
- F S C S: fnId, argBase slot, argCount, dst slot
|
||||
|
||||
Arg count flag:
|
||||
- If high bit of C is set (0x8000), the low 15 bits encode a CallArgsPlan constId.
|
||||
- When not set, C is the raw positional count and tailBlockMode=false.

## 6) Const Pool Encoding (v0)
|
||||
|
||||
Each const entry is encoded as:
|
||||
[tag:U8] [payload...]
|
||||
|
||||
Tags:
|
||||
- 0x00: NULL
|
||||
- 0x01: BOOL (payload: U8 0/1)
|
||||
- 0x02: INT (payload: S64, little-endian)
|
||||
- 0x03: REAL (payload: F64, IEEE-754, little-endian)
|
||||
- 0x04: STRING (payload: U32 length + UTF-8 bytes)
|
||||
- 0x05: OBJ_REF (payload: U32 index into external Obj table)
|
||||
|
||||
Notes:
|
||||
- OBJ_REF is reserved for embedding prebuilt Obj handles if needed.
|
||||
- Strings use UTF-8; length is bytes, not chars.
|
||||
|
||||
## 7) Function Header (binary container)
|
||||
|
||||
Suggested layout for a bytecode function blob:
|
||||
- magic: U32 ("LYBC")
|
||||
- version: U16 (0x0001)
|
||||
- slotWidth: U8 (1,2,4)
|
||||
- ipWidth: U8 (2,4)
|
||||
- constIdWidth: U8 (2,4)
|
||||
- localCount: U32
|
||||
- codeSize: U32 (bytes)
|
||||
- constCount: U32
|
||||
- constPool: [const entries...]
|
||||
- code: [bytecode...]
|
||||
|
||||
Const pool entries use the encoding described in section 6.
|
||||
|
||||
## 8) Sample Bytecode (illustrative)
|
||||
|
||||
Example Lyng:
|
||||
val x = 2
|
||||
val y = 3
|
||||
val z = x + y
|
||||
|
||||
Assume:
|
||||
- localCount = 3 (x,y,z)
|
||||
- argCount = 0
|
||||
- slot width = 1 byte
|
||||
- const pool: [INT 2, INT 3]
|
||||
|
||||
Bytecode:
|
||||
CONST_INT k0 -> s0
|
||||
CONST_INT k1 -> s1
|
||||
ADD_INT s0, s1 -> s2
|
||||
RET_VOID
|
||||
|
||||
Encoded (opcode values symbolic):
|
||||
[OP_CONST_INT][k0][s0]
|
||||
[OP_CONST_INT][k1][s1]
|
||||
[OP_ADD_INT][s0][s1][s2]
|
||||
[OP_RET_VOID]
|
||||
|
||||
## 9) Notes
|
||||
|
||||
- Mixed-mode is allowed: compiler can emit FALLBACK ops for unsupported nodes.
|
||||
- The VM must be suspendable; on suspension, store ip + minimal operand state.
|
||||
- Source mapping uses a separate ip->Pos table, not part of core bytecode.

- **Serialization**: Anonymous objects are **not serializable**. Attempting to encode an anonymous object via `Lynon` will throw a `SerializationException`. This is because their class definition is transient and cannot be safely restored in a different session or process.
|
||||
- **Type Identity**: Every object expression creates a unique anonymous class. Two identical object expressions will result in two different classes with distinct type identities.
|
||||
|
||||
## Nested Declarations
|
||||
|
||||
Lyng allows classes, objects, enums, and type aliases to be declared inside another class. These declarations live in the **class namespace** (not the instance), so they do not capture an outer instance and are accessed with a qualifier.
|
||||
|
||||
```lyng
|
||||
class A {
|
||||
class B(x?)
|
||||
object Inner { val foo = "bar" }
|
||||
type Alias = B
|
||||
enum E { One, Two }
|
||||
}
|
||||
|
||||
val ab = A.B()
|
||||
assertEquals(ab.x, null)
|
||||
assertEquals(A.Inner.foo, "bar")
|
||||
```
|
||||
|
||||
Rules:
|
||||
- **Qualified access**: use `Outer.Inner` for nested classes/objects/enums/aliases. Inside `Outer` you can refer to them by unqualified name unless shadowed.
|
||||
- **No inner semantics**: nested declarations do not capture an instance of the outer class. They are resolved at compile time.
|
||||
- **Visibility**: `private` restricts a nested declaration to the declaring class body (not visible from outside or subclasses).
|
||||
- **Reflection name**: a nested class reports `Outer.Inner` (e.g., `A.B::class.name` is `"A.B"`).
|
||||
- **Type aliases**: behave as aliases of the qualified nested type and are expanded by the type system.
|
||||
|
||||
### Lifted Enum Entries
|
||||
|
||||
Enums can optionally lift their entries into the surrounding class namespace using `*`:
|
||||
|
||||
```lyng
|
||||
class A {
|
||||
enum E* { One, Two }
|
||||
}
|
||||
|
||||
assertEquals(A.One, A.E.One)
|
||||
assertEquals(A.Two, A.E.Two)
|
||||
```
|
||||
|
||||
Notes:
|
||||
- `E*` exposes entries in `A` as if they were direct members (`A.One`).
|
||||
- If a name would conflict with an existing class member, compilation fails (no implicit fallback).
|
||||
- Without `*`, use the normal `A.E.One` form.
|
||||
|
||||
## Properties
|
||||
|
||||
Properties allow you to define member accessors that look like fields but execute code when read or written. Unlike regular fields, properties in Lyng do **not** have automatic backing fields; they are pure accessors.

# Lyng Language Reference for AI Agents (Current Compiler State)
|
||||
|
||||
Purpose: dense, implementation-first reference for generating valid Lyng code.
|
||||
|
||||
Primary sources used: `lynglib/src/commonMain/kotlin/net/sergeych/lyng/{Parser,Token,Compiler,Script,TypeDecl}.kt`, `lynglib/stdlib/lyng/root.lyng`, tests in `lynglib/src/commonTest` and `lynglib/src/jvmTest`.
|
||||
|
||||
## 1. Ground Rules
|
||||
- Resolution is compile-time-first. Avoid runtime name/member lookup assumptions.
|
||||
- `lyng.stdlib` is auto-seeded for normal scripts (default import manager).
|
||||
- Use explicit casts when receiver type is unknown (`Object`/`Obj`).
|
||||
- Prefer modern null-safe operators (`?.`, `?:`/`??`, `?=`, `as?`, `!!`).
|
||||
- Do not rely on fallback opcodes or dynamic member fallback semantics.
|
||||
|
||||
## 2. Lexical Syntax
|
||||
- Comments: `// line`, `/* block */`.
|
||||
- Strings: `"..."` (supports escapes). Multiline string content is normalized by indentation logic.
|
||||
- Supported escapes: `\n`, `\r`, `\t`, `\"`, `\\`, `\uXXXX` (4 hex digits).
|
||||
- Unicode escapes use exactly 4 hex digits (for example: `"\u0416"` -> `Ж`).
|
||||
- Unknown `\x` escapes in strings are preserved literally as two characters (`\` and `x`).
|
||||
- Numbers: `Int` (`123`, `1_000`), `Real` (`1.2`, `1e3`), hex (`0xFF`).
|
||||
- Char: `'a'`, escaped chars supported.
|
||||
- Supported escapes: `\n`, `\r`, `\t`, `\'`, `\\`, `\uXXXX` (4 hex digits).
|
||||
- Backslash character in a char literal must be written as `'\\'` (forms like `'\'` are invalid).
|
||||
- Labels:
|
||||
- statement label: `loop@ for (...) { ... }`
|
||||
- label reference: `break@loop`, `continue@loop`, `return@fnLabel`
|
||||
- Keywords/tokens include (contextual in many places):
|
||||
- declarations: `fun`/`fn`, `val`, `var`, `class`, `object`, `interface`, `enum`, `type`, `init`
|
||||
- modifiers: `private`, `protected`, `static`, `abstract`, `closed`, `override`, `extern`, `open`
|
||||
- flow: `if`, `else`, `when`, `for`, `while`, `do`, `try`, `catch`, `finally`, `throw`, `return`, `break`, `continue`
|
||||
|
||||
## 3. Literals and Core Expressions
|
||||
- Scalars: `null`, `true`, `false`, `void`.
|
||||
- List literal: `[a, b, c]`, spreads with `...`.
|
||||
- Spread positions: beginning, middle, end are all valid: `[...a]`, `[0, ...a, 4]`, `[head, ...mid, tail]`.
|
||||
- Spread source must be a `List` at runtime (non-list spread raises an error).
|
||||
- Map literal: `{ key: value, x:, ...otherMap }`.
|
||||
- `x:` means shorthand `x: x`.
|
||||
- Map spread source must be a `Map`.
|
||||
- Range literals:
|
||||
- inclusive: `a..b`
|
||||
- exclusive end: `a..<b`
|
||||
- open-ended forms are supported (`a..`, `..b`, `..`).
|
||||
- optional step: `a..b step 2`
|
||||
- Lambda literal:
|
||||
- with params: `{ x, y -> x + y }`
|
||||
- implicit `it`: `{ it + 1 }`
|
||||
- Ternary conditional is supported: `cond ? thenExpr : elseExpr`.
|
||||
|
||||
## 3.1 Splats in Calls and Lambdas
|
||||
- Declaration-side variadic parameters use ellipsis suffix:
|
||||
- functions: `fun f(head, tail...) { ... }`
|
||||
- lambdas: `{ x, rest... -> ... }`
|
||||
- Call-side splats use `...expr` and are expanded by argument kind:
|
||||
- positional splat: `f(...[1,2,3])`
|
||||
- named splat: `f(...{ a: 1, b: 2 })` (map-style)
|
||||
- Runtime acceptance for splats:
|
||||
- positional splat accepts `List` and general `Iterable` (iterable is converted to list first).
|
||||
- named splat accepts `Map` with string keys only.
|
||||
- Ordering/validation rules (enforced):
|
||||
- positional argument cannot follow named arguments (except trailing-block parsing case).
|
||||
- positional splat cannot follow named arguments.
|
||||
- duplicate named arguments are errors (including duplicates introduced via named splat).
|
||||
- unknown named parameters are errors.
|
||||
- variadic parameter itself cannot be passed as a named argument (`fun g(args..., tail)` then `g(args: ...)` is invalid).
|
||||
- Trailing block + named arguments:
|
||||
- if the last callable parameter is already provided by name in parentheses, adding a trailing block is invalid.
|
||||
|
||||
## 4. Operators (implemented)
|
||||
- Assignment: `=`, `+=`, `-=`, `*=`, `/=`, `%=`, `?=`.
|
||||
- Logical: `||`, `&&`, unary `!`.
|
||||
- Bitwise: `|`, `^`, `&`, `~`, shifts `<<`, `>>`.
|
||||
- Equality/comparison: `==`, `!=`, `===`, `!==`, `<`, `<=`, `>`, `>=`, `<=>`, `=~`, `!~`.
|
||||
- Type/containment: `is`, `!is`, `in`, `!in`, `as`, `as?`.
|
||||
- Null-safe family:
|
||||
- member access: `?.`
|
||||
- safe index: `?[i]`
|
||||
- safe invoke: `?(...)`
|
||||
- safe block invoke: `?{ ... }`
|
||||
- elvis: `?:` and `??`.
|
||||
- Increment/decrement: prefix and postfix `++`, `--`.
|
||||
|
||||
## 5. Declarations
|
||||
- Variables:
|
||||
- `val` immutable, `var` mutable.
|
||||
- top-level/local `val` must be initialized.
|
||||
- class `val` may be late-initialized, but must be assigned in class body/init before class parse ends.
|
||||
- destructuring declaration: `val [a, b, rest...] = expr`.
|
||||
- destructuring declaration details:
|
||||
- allowed in `val` and `var` declarations.
|
||||
- supports nested patterns: `val [a, [b, c...], d] = rhs`.
|
||||
- supports at most one splat (`...`) per pattern level.
|
||||
- RHS must be a `List`.
|
||||
- without splat: RHS must have at least as many elements as pattern arity.
|
||||
- with splat: head/tail elements are bound directly, splat receives a `List`.
|
||||
- Functions:
|
||||
- `fun` and `fn` are equivalent.
|
||||
- full body: `fun f(x) { ... }`
|
||||
- shorthand: `fun f(x) = expr`.
|
||||
- generics: `fun f<T>(x: T): T`.
|
||||
- extension functions: `fun Type.name(...) { ... }`.
|
||||
- delegated callable: `fun f(...) by delegate`.
|
||||
- Type aliases:
|
||||
- `type Name = TypeExpr`
|
||||
- generic: `type Box<T> = List<T>`
|
||||
- aliases are expanded structurally.
|
||||
- Classes/objects/enums/interfaces:
|
||||
- `interface` is parsed as abstract class synonym.
|
||||
- `object` supports named singleton and anonymous object expression forms.
|
||||
- enums support lifted entries: `enum E* { A, B }`.
|
||||
- multiple inheritance is supported; override is enforced when overriding base members.
|
||||
- Properties/accessors in class body:
|
||||
- accessor form supports `get`/`set`, including `private set`/`protected set`.
|
||||
|
||||
## 6. Control Flow
|
||||
- `if` is expression-like.
|
||||
- `when(value) { ... }` supported.
|
||||
- branch conditions support equality, `in`, `!in`, `is`, `!is`, and `nullable` predicate.
|
||||
- `when { ... }` (subject-less) is currently not implemented.
|
||||
- Loops: `for`, `while`, `do ... while`.
|
||||
- loop `else` blocks are supported.
|
||||
- `break value` can return a loop result.
|
||||
- Exceptions: `try/catch/finally`, `throw`.
|
||||
|
||||
## 6.1 Destructuring Assignment (implemented)
|
||||
- Reassignment form is supported (not only declaration):
|
||||
- `[x, y] = [y, x]`
|
||||
- Semantics match destructuring declaration:
|
||||
- nested patterns allowed.
|
||||
- at most one splat per pattern level.
|
||||
- RHS must be a `List`.
|
||||
- too few RHS elements raises runtime error.
|
||||
- Targets in pattern are variables parsed from identifier patterns.
|
||||
|
||||
## 7. Type System (current behavior)
|
||||
- Non-null by default (`T`), nullable with `T?`.
|
||||
- `as` (checked cast), `as?` (safe cast returning `null`), `!!` non-null assertion.
|
||||
- Type expressions support:
|
||||
- unions `A | B`
|
||||
- intersections `A & B`
|
||||
- function types `(A, B)->R` and receiver form `Receiver.(A)->R`
|
||||
- variadics in function type via ellipsis (`T...`)
|
||||
- Generics:
|
||||
- type params on classes/functions/type aliases
|
||||
- bounds via `:` with union/intersection expressions
|
||||
- declaration-site variance via `in` / `out`
|
||||
- Generic function/class/type syntax examples:
|
||||
- function: `fun choose<T>(a: T, b: T): T = a`
|
||||
- class: `class Box<T>(val value: T)`
|
||||
- alias: `type PairList<T> = List<List<T>>`
|
||||
- Untyped params default to `Object` (`x`) or `Object?` (`x?` shorthand).
|
||||
- Untyped `var x` starts as `Unset`; first assignment fixes type tracking in compiler.
|
||||
|
||||
## 7.1 Generics Runtime Model and Bounds (AI-critical)
|
||||
- Lyng generic type information is operational in script execution contexts; do not assume JVM-style full erasure.
|
||||
- Generic call type arguments can be:
|
||||
- explicit at call site (`f<Int>(1)` style),
|
||||
- inferred from runtime values/declared arg types,
|
||||
- defaulted from type parameter defaults (or `Any` fallback).
|
||||
- At function execution, generic type parameters are runtime-bound as constants in scope:
|
||||
- simple non-null class-like types are bound as `ObjClass`,
|
||||
- complex/nullable/union/intersection forms are bound as `ObjTypeExpr`.
|
||||
- Practical implication for generated code:
|
||||
- inside generic code, treat type params as usable type objects in `is`/`in`/type-expression logic (not as purely compile-time placeholders).
|
||||
- example pattern: `if (value is T) { ... }`.
|
||||
- Bound syntax (implemented):
|
||||
- intersection bound: `fun f<T: A & B>(x: T) { ... }`
|
||||
- union bound: `fun g<T: A | B>(x: T) { ... }`
|
||||
- Bound checks happen at two points:
|
||||
- compile-time call checking for resolvable generic calls,
|
||||
- runtime re-check while binding type params for actual invocation.
|
||||
- Bound satisfaction is currently class-hierarchy based for class-resolvable parts (including union/intersection combination rules).
|
||||
- Keep expectations realistic:
|
||||
- extern-generic runtime ABI for full instance-level generic metadata is still proposal-level (`proposals/extern_generic_runtime_abi.md`), so avoid assuming fully materialized generic-instance metadata everywhere.
|
||||
|
||||
## 7.2 Differences vs Java / Kotlin / Scala
|
||||
- Java:
|
||||
- Java generics are erased at runtime (except reflection metadata and raw `Class` tokens).
|
||||
- Lyng generic params in script execution are runtime-bound type objects, so generated code can reason about `T` directly.
|
||||
- Kotlin:
|
||||
- Kotlin on JVM is mostly erased; full runtime type access usually needs `inline reified`.
|
||||
- Lyng generic function execution binds `T` without requiring an inline/reified escape hatch.
|
||||
- Scala:
|
||||
- Scala has richer static typing but still runs on JVM erasure model unless carrying explicit runtime evidence (`TypeTag`, etc.).
|
||||
- Lyng exposes runtime-bound type expressions/classes directly in generic execution scope.
|
||||
- AI generation rule:
|
||||
- do not port JVM-language assumptions like “`T` unavailable at runtime unless reified/tagged”.
|
||||
- in Lyng, prefer direct type-expression-driven branching when useful, but avoid assuming extern object generic args are always introspectable today.
|
||||
|
||||
## 8. OOP, Members, and Dispatch
|
||||
- Multiple inheritance with C3-style linearization behavior is implemented in class machinery.
|
||||
- Disambiguation helpers are supported:
|
||||
- qualified this: `this@Base.member()`
|
||||
- cast view: `(obj as Base).member()`
|
||||
- On unknown receiver types, compiler allows only Object-safe members:
|
||||
- `toString`, `toInspectString`, `let`, `also`, `apply`, `run`
|
||||
- Other members require known receiver type or explicit cast.
|
||||
|
||||
## 9. Delegation (`by`)
|
||||
- Works for `val`, `var`, and `fun`.
|
||||
- Expected delegate hooks in practice:
|
||||
- `getValue(thisRef, name)`
|
||||
- `setValue(thisRef, name, newValue)`
|
||||
- `invoke(thisRef, name, args...)` for delegated callables
|
||||
- optional `bind(name, access, thisRef)`
|
||||
- `@Transient` is recognized for declarations/params and affects serialization/equality behavior.
|
||||
|
||||
## 10. Modules and Imports
|
||||
- `package` and `import module.name` are supported.
|
||||
- Import form is module-only (no aliasing/selective import syntax in parser).
|
||||
- Default module ecosystem includes:
|
||||
- auto-seeded: `lyng.stdlib`
|
||||
- available by import: `lyng.observable`, `lyng.buffer`, `lyng.serialization`, `lyng.time`
|
||||
- extra module (when installed): `lyng.io.fs`, `lyng.io.process`
|
||||
|
||||
## 11. Current Limitations / Avoid
|
||||
- No subject-less `when { ... }` yet.
|
||||
- No regex literal tokenization (`/.../`); use `Regex("...")` or `"...".re`.
|
||||
- Do not generate runtime name fallback patterns from legacy docs.

# AI notes: avoid Kotlin/Wasm invalid IR with suspend lambdas
|
||||
|
||||
## Do
|
||||
- Prefer explicit `object : Statement()` with `override suspend fun execute(...)` when building compiler statements.
|
||||
- Keep `Statement` objects non-lambda, especially in compiler hot paths like parsing/var declarations.
|
||||
- If you need conditional behavior, return early in `execute` instead of wrapping `parseExpression()` with `statement(...) { ... }`.
|
||||
- When wasmJs tests hang in the browser, first check `wasmJsNodeTest` for a compile error; hangs often mean module instantiation failed.
|
||||
|
||||
## Don't
|
||||
- Do not create suspend lambdas inside `Statement` factories (`statement { ... }`) for wasm targets.
|
||||
- Do not "fix" hangs by increasing browser timeouts; it masks invalid wasm generation.
|
||||
|
||||
## Debugging tips
|
||||
- Look for `$invokeCOROUTINE$` in wasm function names when mapping failures.
|
||||
- If node test logs a wasm compile error, the browser hang is likely the same root cause.

# Lyng Stdlib Reference for AI Agents (Compact)
|
||||
|
||||
Purpose: fast overview of what is available by default and what must be imported.
|
||||
|
||||
Sources: `lynglib/src/commonMain/kotlin/net/sergeych/lyng/Script.kt`, `lynglib/stdlib/lyng/root.lyng`, `lynglib/src/commonMain/kotlin/net/sergeych/lyng/stdlib_included/observable_lyng.kt`.
|
||||
|
||||
## 1. Default Availability
|
||||
- Normal scripts are auto-seeded with `lyng.stdlib` (default import manager path).

|
||||
- Delegation types: `Delegate`, `DelegateContext`.
|
||||
- Regex types: `Regex`, `RegexMatch`.
|
||||
- Also present: `Math.PI` namespace constant.
|
||||
|
||||
## 4. `lyng.stdlib` Module Surface (from `root.lyng`)
|
||||
### 4.1 Extern class declarations
|
||||
- Exceptions/delegation base: `Exception`, `IllegalArgumentException`, `NotImplementedException`, `Delegate`.
|
||||
- Collections and iterables: `Iterable<T>`, `Iterator<T>`, `Collection<T>`, `Array<T>`, `List<T>`, `ImmutableList<T>`, `Set<T>`, `ImmutableSet<T>`, `Map<K,V>`, `ImmutableMap<K,V>`, `MapEntry<K,V>`, `RingBuffer<T>`.
|
||||
- Host iterator bridge: `KotlinIterator<T>`.
|
||||
- Random APIs: `extern object Random`, `extern class SeededRandom`.
|
||||
|
||||
### 4.2 High-use extension APIs

- Search/predicates: `findFirst`, `findFirstOrNull`, `any`, `all`, `count`, `first`, `last`.
|
||||
- Mapping/aggregation: `map`, `flatMap`, `flatten`, `sum`, `sumOf`, `minOf`, `maxOf`.
|
||||
- Ordering: `sorted`, `sortedBy`, `shuffled`, `List.sort`, `List.sortBy`.
|
||||
- String helper: `joinToString`, `String.re`.
|
||||
|
||||
### 4.3 Delegation helpers
|
||||
- `enum DelegateAccess { Val, Var, Callable }`
|
||||
- `interface Delegate<T,ThisRefType=void>` with `getValue`, `setValue`, `invoke`, `bind`.
|
||||
- `class lazy<T,...>` delegate implementation.
|
||||
- `fun with(self, block)` helper.
|
||||
|
||||
### 4.4 Other module-level symbols
|
||||
- `$~` (last regex match object).
|
||||
- `TODO(message?)` utility.
|
||||
- `StackTraceEntry` class.
|
||||
- `Random.nextInt()`, `Random.nextFloat()`, `Random.next(range)`, `Random.seeded(seed)`.
|
||||
- `SeededRandom.nextInt()`, `SeededRandom.nextFloat()`, `SeededRandom.next(range)`.
|
||||
|
||||
## 5. Additional Built-in Modules (import explicitly)
|
||||
- `import lyng.observable`
|
||||
- `Observable`, `Subscription`, `ObservableList`, `ListChange` and change subtypes, `ChangeRejectionException`.
|
||||
- `import lyng.buffer`

||||
- `import lyng.serialization`
|
||||

|
||||
- `import lyng.time`
|
||||
- `Instant`, `DateTime`, `Duration`, and module `delay`.
|
||||
|
||||
## 6. Optional (lyngio) Modules
|
||||
Requires installing `lyngio` into the import manager from host code.
|
||||
- `import lyng.io.fs` (filesystem `Path` API)
|
||||
- `import lyng.io.process` (process execution API)
|
||||
- `import lyng.io.console` (console capabilities, geometry, ANSI/output, events)
|
||||
|
||||
## 7. AI Generation Tips
|
||||
- Assume `lyng.stdlib` APIs exist in regular script contexts.
|
||||
- For platform-sensitive code (`fs`, `process`, `console`), gate assumptions and mention required module install.
|
||||
- Prefer extension-method style (`items.filter { ... }`) and standard scope helpers (`let`/`also`/`apply`/`run`).

Ellipsis are used to declare variadic arguments. It basically means "all the arguments available here".

|

### 3) Preferred: bind extern globals from Kotlin
|
||||
### 3) Define variables from Kotlin
|
||||
|
||||
For module-level APIs, the default workflow is:
|
||||
|
||||
1. declare globals in Lyng using `extern fun` / `extern val` / `extern var`;
|
||||
2. bind Kotlin implementation via `ModuleScope.globalBinder()`.
|
||||
To expose data to Lyng, add constants (read‑only) or mutable variables to the scope. All values in Lyng are `Obj` instances; the core types live in `net.sergeych.lyng.obj`.
|
||||
|
||||
```kotlin
|
||||
import net.sergeych.lyng.bridge.*
|
||||
import net.sergeych.lyng.obj.ObjInt
|
||||
import net.sergeych.lyng.obj.ObjString

||||

|
||||

||||

|
||||
extern val globalVersion: String
|
||||

|
||||
// Mutable variable: create or update
|
||||
scope.addOrUpdateItem("counter", ObjInt(0))
|
||||
|
||||
val binder = module.globalBinder()
|
||||
|
||||
binder.bindGlobalFun1<Int>("globalFun") { v ->
|
||||
ObjInt.of((v + 1).toLong())
|
||||
}
|
||||
|
||||
var prop = "initial"
|
||||
binder.bindGlobalVar(
|
||||
name = "globalProp",
|
||||
get = { prop },
|
||||
set = { prop = it }
|
||||
)
|
||||
|
||||
binder.bindGlobalVar(
|
||||
name = "globalVersion",
|
||||
get = { "1.0.0" } // readonly: setter omitted
|
||||
)
|
||||
}
|
||||
// Use it from Lyng
|
||||
scope.eval("counter = counter + 1")
|
||||
```
|
||||
|
||||
Usage from Lyng:
|
||||
|
||||
```lyng
|
||||
import my.api
|
||||
|
||||
assertEquals(42, globalFun(41))
|
||||
assertEquals("initial", globalProp)
|
||||
globalProp = "changed"
|
||||
assertEquals("changed", globalProp)
|
||||
assertEquals("1.0.0", globalVersion)
|
||||
```
|
||||
|
||||
For custom argument handling and full runtime access:
|
||||
Tip: Lyng values can be converted back to Kotlin with `toKotlin(scope)`:
|
||||
|
||||
```kotlin
|
||||
binder.bindGlobalFun("sum3") {
|
||||
requireExactCount(3)
|
||||
ObjInt.of((int(0) + int(1) + int(2)).toLong())
|
||||
}
|
||||
|
||||
binder.bindGlobalFunRaw("echoRaw") { _, args ->

||||
args.firstAndOnly()
|
||||
}
|
||||
val current = (scope.eval("counter")).toKotlin(scope) // Any? (e.g., Int/Double/String/List)

### 4) Low-level: direct functions/variables from Kotlin
|
||||
### 4) Add Kotlin‑backed functions
|
||||
|
||||
Use this when you intentionally want raw `Scope` APIs. For most module APIs, prefer section 3.
|
||||
Use `Scope.addFn`/`addVoidFn` to register functions implemented in Kotlin. Inside the lambda, use `this.args` to access arguments and return an `Obj`.

||||
|
||||

||||

||||
|
||||
Scope-backed Kotlin lambdas receive a `ScopeFacade` (not a full `Scope`). For migration and convenience, these utilities are available on the facade:
|
||||
|
||||
- Access: `args`, `pos`, `thisObj`, `get(name)`

- Args helpers: `requiredArg<T>()`, `requireOnlyArg<T>()`, `requireExactCount(...)`, `requireNoArgs()`, `thisAs<T>()`

|
||||
|
||||
If you truly need the full `Scope` (e.g., for low-level interop), use `requireScope()` explicitly.
|
||||
|
||||
### 5) Add Kotlin‑backed fields
|
||||
|
||||
If you need a simple field (with a value) instead of a computed property, use `createField`. This adds a field to the class that will be present in all its instances.

|
||||
|
||||
### 6.5) Preferred: bind Kotlin implementations to declared Lyng classes
|
||||
|
||||
For extensions and libraries, the **preferred** workflow is Lyng‑first: declare the class and its members in Lyng, then bind the Kotlin implementations using the bridge.
|
||||
|
||||
This keeps Lyng semantics (visibility, overrides, type checks) in Lyng, while Kotlin supplies the behavior.
|
||||
|
||||
Pure extern declarations use the simplified rule set:
|
||||
- `extern class` / `extern object` are declaration-only ABI surfaces.
|
||||
- Every member in their body is implicitly extern (you may still write `extern`, but it is redundant).
|
||||
- Plain Lyng member implementations inside `extern class` / `extern object` are not allowed.
|
||||
- Put Lyng behavior into regular classes or extension methods.
|
||||
|
||||
```lyng
|
||||
// Lyng side (in a module)
|
||||
class Counter {
|
||||
extern var value: Int
|
||||
extern fun inc(by: Int): Int
|
||||
}
|
||||
```
|
||||
|
||||
Note: members of `extern class` / `extern object` are treated as extern by default, so the compiler emits ABI slots that Kotlin bindings attach to. This applies to functions and properties bound via `addFun` / `addVal` / `addVar`.
|
||||
|
||||
Example of pure extern class declaration:
|
||||
|
||||
```lyng
|
||||
extern class HostCounter {
|
||||
var value: Int
|
||||
fun inc(by: Int): Int
|
||||
}
|
||||
```
|
||||
|
||||
If you need Lyng-side convenience behavior, add it as an extension:
|
||||
|
||||
```lyng
|
||||
fun HostCounter.bump() = inc(1)
|
||||
```
|
||||
|
||||
```kotlin
|
||||
// Kotlin side (binding)
|
||||
val moduleScope = Script.newScope() // or an existing module scope
|
||||
moduleScope.eval("class Counter { extern var value: Int; extern fun inc(by: Int): Int }")
|
||||
|
||||
moduleScope.bind("Counter") {
|
||||
addVar(
|
||||
name = "value",
|
||||
get = { thisObj.readField(this, "value").value },
|
||||
set = { v -> thisObj.writeField(this, "value", v) }
|
||||
)
|
||||
addFun("inc") {
|
||||
val by = args.requiredArg<ObjInt>(0).value
|
||||
val current = thisObj.readField(this, "value").value as ObjInt
|
||||
val next = ObjInt(current.value + by)
|
||||
thisObj.writeField(this, "value", next)
|
||||
next
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Notes:
|
||||
|
||||
- Binding must happen **before** the first instance is created.
|
||||
- Use [LyngClassBridge] to bind by name/module, or by an already resolved `ObjClass`.
|
||||
- Use `ObjInstance.data` / `ObjClass.classData` to attach Kotlin‑side state when needed.
|
||||
|
||||
### 6.5a) Bind Kotlin implementations to declared Lyng objects
|
||||
|
||||
For `extern object` declarations, bind implementations to the singleton instance using `ModuleScope.bindObject`.
|
||||
This mirrors class binding but targets an already created object instance.
|
||||
As with class binding, you must first add/evaluate the Lyng declaration into that module scope, then bind Kotlin handlers.
|
||||
|
||||
```kotlin
|
||||
// Kotlin side (binding)
|
||||
val moduleScope = importManager.createModuleScope(Pos.builtIn, "bridge.obj")
|
||||
|
||||
// 1) Seed the module with the Lyng declaration first
|
||||
moduleScope.eval("""
|
||||
extern object HostObject {
|
||||
extern fun add(a: Int, b: Int): Int
|
||||
extern val status: String
|
||||
extern var count: Int
|
||||
}
|
||||
""".trimIndent())
|
||||
|
||||
// 2) Then bind Kotlin implementations to that declared object
|
||||
moduleScope.bindObject("HostObject") {
|
||||
classData = "OK"
|
||||
init { _ -> data = 0L }
|
||||
addFun("add") {
|
||||
val a = args.requiredArg<ObjInt>(0).value
|
||||
val b = args.requiredArg<ObjInt>(1).value
|
||||
ObjInt.of(a + b)
|
||||
}
|
||||
addVal("status") { ObjString(classData as String) }
|
||||
addVar(
|
||||
"count",
|
||||
get = { ObjInt.of((thisObj as ObjInstance).data as Long) },
|
||||
set = { value -> (thisObj as ObjInstance).data = (value as ObjInt).value }
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
Notes:
|
||||
|
||||
- Required order: declare/eval Lyng object in the module first, then call `bindObject(...)`.
|
||||
This is the pattern covered by `BridgeBindingTest.testExternObjectBinding`.
|
||||
- Members must be extern (explicitly, or implicitly via `extern object`) so the compiler emits ABI slots for Kotlin bindings.
|
||||
- You can also bind by name/module via `LyngObjectBridge.bind(...)`.
|
||||
|
||||
Minimal `extern fun` example:
|
||||
|
||||
```kotlin
|
||||
val moduleScope = importManager.createModuleScope(Pos.builtIn, "bridge.ping")
|
||||
|
||||
moduleScope.eval("""
|
||||
extern object HostObject {
|
||||
extern fun ping(): Int
|
||||
}
|
||||
""".trimIndent())
|
||||
|
||||
moduleScope.bindObject("HostObject") {
|
||||
addFun("ping") { ObjInt.of(7) }
|
||||
}
|
||||
```
|
||||
|
||||
### 6.6) Preferred: Kotlin reflection bridge for call‑by‑name
|
||||
|
||||
For Kotlin code that needs dynamic access to Lyng variables, functions, or members, use the bridge resolver.
|
||||
It provides explicit, cached handles and predictable lookup rules.
|
||||
|
||||
```kotlin
|
||||
val scope = Script.newScope()
|
||||
scope.eval("""
|
||||
val x = 40
|
||||
fun add(a, b) = a + b
|
||||
class Box { var value = 1 }
|
||||
""")
|
||||
|
||||
val resolver = scope.resolver()
|
||||
|
||||
// Read a top‑level value
|
||||
val x = resolver.resolveVal("x").get(scope)
|
||||
|
||||
// Call a function by name (cached inside the resolver)
|
||||
val sum = (resolver as BridgeCallByName).callByName(scope, "add", Arguments(ObjInt(1), ObjInt(2)))
|
||||
|
||||
// Member access
|
||||
val box = scope.eval("Box()")
|
||||
val valueHandle = resolver.resolveMemberVar(box, "value")
|
||||
valueHandle.set(scope, ObjInt(10))
|
||||
val value = valueHandle.get(scope)
|
||||
```
|
||||
|
||||
### 7) Read variable values back in Kotlin
|
||||
|
||||
The simplest approach: evaluate an expression that yields the value and convert it.

# Generics and type expressions
|
||||
|
||||
This document covers generics, bounds, unions/intersections, and the rules for type expressions in Lyng.
|
||||
|
||||
# Generic parameters
|
||||
|
||||
Declare type parameters with `<...>` on functions and classes:
|
||||
|
||||
fun id<T>(x: T): T = x
|
||||
class Box<T>(val value: T)
|
||||
|
||||
Type arguments are usually inferred at call sites:
|
||||
|
||||
val b = Box(10) // Box<Int>
|
||||
val s = id("ok") // T is String
|
||||
|
||||
# Bounds
|
||||
|
||||
Use `:` to set bounds. Bounds may be unions (`|`) or intersections (`&`):
|
||||
|
||||
fun sum<T: Int | Real>(x: T, y: T) = x + y
|
||||
class Named<T: Iterable & Comparable>(val data: T)
|
||||
|
||||
Bounds are checked at compile time. For union bounds, the argument must fit at least one option. For intersection bounds, it must fit all options.
|
||||
|
||||
# Variance
|
||||
|
||||
Generic types are invariant by default. You can specify declaration-site variance:
|
||||
|
||||
class Source<out T>(val value: T)
|
||||
class Sink<in T> { fun accept(x: T) { ... } }
|
||||
|
||||
`out` makes the type covariant (produced), `in` makes it contravariant (consumed).
|
||||
|
||||
# Type aliases
|
||||
|
||||
Type aliases name type expressions (including unions/intersections):
|
||||
|
||||
type Num = Int | Real
|
||||
type AB = A & B
|
||||
|
||||
Aliases can be generic and can use bounds and defaults:
|
||||
|
||||
type Maybe<T> = T?
|
||||
type IntList<T: Int> = List<T>
|
||||
|
||||
Aliases expand to their underlying type expressions. They can be used anywhere a type expression is expected.
|
||||
|
||||
# Inference rules
|
||||
|
||||
- Literals set obvious types (`1` is `Int`, `1.0` is `Real`, etc.).
|
||||
- Empty list literals default to `List<Object>` unless constrained by context.
|
||||
- Non-empty list literals infer element type as a union of element types.
|
||||
- Map literals infer key and value types; named keys are `String`.
|
||||
|
||||
Examples:
|
||||
|
||||
val a = [1, 2, 3] // List<Int>
|
||||
val b = [1, "two", true] // List<Int | String | Bool>
|
||||
val c: List<Int> = [] // List<Int>
|
||||
|
||||
val m1 = { "a": 1, "b": 2 } // Map<String, Int>
|
||||
val m2 = { "a": 1, "b": "x" } // Map<String, Int | String>
|
||||
val m3 = { ...m1, "c": true } // Map<String, Int | Bool>
|
||||
|
||||
Map spreads carry key/value types when possible.
|
||||
|
||||
Spreads propagate element type when possible:
|
||||
|
||||
val base = [1, 2]
|
||||
val mix = [...base, 3] // List<Int>
|
||||
|
||||
# Type expressions
|
||||
|
||||
Type expressions include simple types, generics, unions, and intersections:
|
||||
|
||||
Int
|
||||
List<String>
|
||||
Int | String
|
||||
Iterable & Comparable
|
||||
|
||||
These type expressions can appear in casts and `is` checks.
|
||||
|
||||
# `is`, `in`, and `==` with type expressions
|
||||
|
||||
There are two categories of `is` checks:
|
||||
|
||||
1) Value checks: `x is T`
|
||||
- `x` is a value, `T` is a type expression.
|
||||
- This is a runtime instance check.
|
||||
|
||||
2) Type checks: `T1 is T2`
|
||||
- both sides are type expressions (class objects or unions/intersections).
|
||||
- This is a *type-subset* check: every value of `T1` must fit in `T2`.
|
||||
|
||||
Exact type expression equality uses `==` and is structural (union/intersection order does not matter).
|
||||
|
||||
Includes checks use `in` with type expressions:
|
||||
|
||||
A in T
|
||||
|
||||
This means `A` is a subset of `T` (the same relation as `A is T`).
|
||||
|
||||
Examples (T = A | B):
|
||||
|
||||
T == A // false
|
||||
T is A // false
|
||||
A in T // true
|
||||
B in T // true
|
||||
T is A | B // true
|
||||
|
||||
# Nullability checks for types
|
||||
|
||||
Use `is nullable` to check whether a type expression accepts `null`:
|
||||
|
||||
T is nullable
|
||||
T !is nullable
|
||||
|
||||
This works with concrete and generic types:
|
||||
|
||||
fun describe<T>(x: T): String = when (T) {
|
||||
nullable -> "nullable"
|
||||
else -> "non-null"
|
||||
}
|
||||
|
||||
Equivalent legacy form:
|
||||
|
||||
null is T
|
||||
|
||||
# Practical examples
|
||||
|
||||
fun acceptInts<T: Int>(xs: List<T>) { }
|
||||
acceptInts([1, 2, 3])
|
||||
// acceptInts([1, "a"]) -> compile-time error
|
||||
|
||||
fun f<T>(list: List<T>) {
|
||||
assert( T is Int | String | Bool )
|
||||
assert( !(T is Int) )
|
||||
assert( Int in T )
|
||||
}
|
||||
f([1, "two", true])
|
||||
|
||||
# Notes
|
||||
|
||||
- `T` is reified as a type expression when needed (e.g., union/intersection). When it is a single class, `T` is that class object.
|
||||
- Type expression checks are compile-time where possible; runtime checks only happen for `is` on values and explicit casts.

### lyng.io.console
|
||||
|
||||
`lyng.io.console` provides optional rich console support for terminal applications.
|
||||
|
||||
> **Note:** this module is part of `lyngio`. It must be explicitly installed into the import manager by host code.
|
||||
>
|
||||
> **CLI note:** the `lyng` CLI now installs `lyng.io.console` in its base scope by default, so scripts can simply `import lyng.io.console`.
|
||||
|
||||
#### Install in host
|
||||
|
||||
```kotlin
|
||||
import net.sergeych.lyng.Script
|
||||
import net.sergeych.lyng.io.console.createConsoleModule
|
||||
import net.sergeych.lyngio.console.security.PermitAllConsoleAccessPolicy
|
||||
|
||||
suspend fun initScope() {
|
||||
val scope = Script.newScope()
|
||||
createConsoleModule(PermitAllConsoleAccessPolicy, scope)
|
||||
}
|
||||
```
|
||||
|
||||
#### Use in Lyng script
|
||||
|
||||
```lyng
|
||||
import lyng.io.console
|
||||
|
||||
println("supported = " + Console.isSupported())
|
||||
println("tty = " + Console.isTty())
|
||||
println("ansi = " + Console.ansiLevel())
|
||||
println("geometry = " + Console.geometry())
|
||||
|
||||
Console.write("hello\n")
|
||||
Console.home()
|
||||
Console.clear()
|
||||
Console.moveTo(1, 1)
|
||||
Console.clearLine()
|
||||
Console.enterAltScreen()
|
||||
Console.leaveAltScreen()
|
||||
Console.setCursorVisible(true)
|
||||
Console.flush()
|
||||
```
|
||||
|
||||
#### Tetris sample
|
||||
|
||||
The repository includes a full interactive Tetris sample that demonstrates:
|
||||
|
||||
- alternate screen rendering
|
||||
- raw keyboard input
|
||||
- resize handling
|
||||
- typed console events
|
||||
|
||||
|
||||
|
||||
Run it from the project root in a real TTY:
|
||||
|
||||
```bash
|
||||
lyng examples/tetris_console.lyng
|
||||
```
|
||||
|
||||
#### API
|
||||
|
||||
- `Console.isSupported(): Bool` — whether console control is available on this platform/runtime.
|
||||
- `Console.isTty(): Bool` — whether output is attached to a TTY.
|
||||
- `Console.ansiLevel(): ConsoleAnsiLevel` — `NONE`, `BASIC16`, `ANSI256`, `TRUECOLOR`.
|
||||
- `Console.geometry(): ConsoleGeometry?` — `{columns, rows}` as typed object or `null`.
|
||||
- `Console.details(): ConsoleDetails` — consolidated capability object.
|
||||
- `Console.write(text: String)` — writes to console output.
|
||||
- `Console.flush()` — flushes buffered output.
|
||||
- `Console.home()` — moves cursor to top-left.
|
||||
- `Console.clear()` — clears visible screen.
|
||||
- `Console.moveTo(row: Int, column: Int)` — moves cursor to 1-based row/column.
|
||||
- `Console.clearLine()` — clears current line.
|
||||
- `Console.enterAltScreen()` — switch to alternate screen buffer.
|
||||
- `Console.leaveAltScreen()` — return to normal screen buffer.
|
||||
- `Console.setCursorVisible(visible: Bool)` — shows/hides cursor.
|
||||
- `Console.events(): ConsoleEventStream` — endless iterable source of typed events: `ConsoleResizeEvent`, `ConsoleKeyEvent`.
|
||||
- `Console.setRawMode(enabled: Bool): Bool` — requests raw input mode, returns `true` if changed.
|
||||
|
||||
#### Event Iteration
|
||||
|
||||
Use events from a loop, typically in a separate coroutine:
|
||||
|
||||
```lyng
|
||||
launch {
|
||||
for (ev in Console.events()) {
|
||||
if (ev is ConsoleKeyEvent) {
|
||||
// handle key
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Event format
|
||||
|
||||
`Console.events()` emits `ConsoleEvent` with:
|
||||
|
||||
- `type: ConsoleEventType` — `UNKNOWN`, `RESIZE`, `KEY_DOWN`, `KEY_UP`
|
||||
|
||||
Additional fields:
|
||||
|
||||
- `ConsoleResizeEvent`: `columns`, `rows`
|
||||
- `ConsoleKeyEvent`: `key`, `code`, `ctrl`, `alt`, `shift`, `meta`
|
||||
|
||||
#### Security policy
|
||||
|
||||
The module uses `ConsoleAccessPolicy` with operations:
|
||||
|
||||
- `WriteText(length)`
|
||||
- `ReadEvents`
|
||||
- `SetRawMode(enabled)`
|
||||
|
||||
For permissive mode, use `PermitAllConsoleAccessPolicy`.

# `.lyng.d` Definition Files
|
||||
|
||||
`.lyng.d` files declare Lyng symbols for tooling without shipping runtime implementations. The IntelliJ IDEA plugin merges
|
||||
all `*.lyng.d` files from the current directory and its parent directories into the active file’s analysis, enabling:
|
||||
|
||||
- completion
|
||||
- navigation
|
||||
- error checking for declared symbols
|
||||
- Quick Docs for declarations defined in `.lyng.d`
|
||||
|
||||
Place `*.lyng.d` files next to the code they describe (or in a parent folder). The plugin will pick them up automatically.
|
||||
|
||||
## Writing `.lyng.d` Files
|
||||
|
||||
You can declare any language-level symbol in a `.lyng.d` file. Use doc comments before declarations to make Quick Docs
|
||||
work in the IDE. The doc parser accepts standard comments (`/** ... */` or `// ...`) and supports tags like `@param`.
|
||||
|
||||

|

Notes:
|

- Use real bodies if the declaration is not `extern` or `abstract`.

- If you need purely declarative stubs, prefer `extern` members (see `embedding.md`).

## Doc Comment Format
|
||||
|
||||
Doc comments are picked up when they immediately precede a declaration.

/**
|
||||
* A sample function.
|
||||
* @param name user name

```
|
||||
|
||||
## Generating `.lyng.d` Files
|
||||
|
||||
You can generate `.lyng.d` as part of your build. A common approach is to write a Gradle task that emits a file from a
|
||||
template or a Kotlin data model.
|
||||
|
||||
Example (pseudo-code):
|
||||
|
||||
```kotlin
|
||||
tasks.register("generateLyngDefs") {
|
||||
doLast {
|
||||
val out = file("src/main/lyng/api.lyng.d")
|
||||
out.writeText(
|
||||
"""
|
||||
/** Generated API */
|
||||
fun ping(): Int
|
||||
""".trimIndent()
|
||||
)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Place the generated file in your source tree, and the IDE will load it automatically.

We hereby publish a new version of Lyng, 1.0.8-SNAPSHOT, which uses `kotlin.time.Instant` and `kotlin.time.Clock` instead of `kotlinx.datetime.Instant` and `kotlinx.datetime.Clock`. It is in other aspects compatible also with Lynon encoded binaries. You might need to migrate your code to use `kotlin.time` types. (LocalDateTime/TimeZone still come from `kotlinx.datetime`.)

### Closures inside coroutine helpers (launch/flow)
|
||||
|
||||
Closures executed by `launch { ... }` and `flow { ... }` use **compile‑time resolution** just like any other Lyng code:
|
||||
Closures executed by `launch { ... }` and `flow { ... }` resolve names using the `ClosureScope` rules:
|
||||
|
||||
- **Captured locals are slots**: outer locals are resolved at compile time and captured as frame‑slot references, so they remain visible across suspension points.
|
||||
- **Members are statically resolved**: member access requires a statically known receiver type or an explicit cast (except `Object` members).
|
||||
- **No runtime fallbacks**: there is no dynamic name lookup or “search parent scopes” at runtime for missing symbols.
|
||||
1. **Current frame locals and arguments**: Variables defined within the current closure execution.
|
||||
2. **Captured lexical ancestry**: Outer local variables captured at the site where the closure was defined (the "lexical environment").
|
||||
3. **Captured receiver members**: If the closure was defined within a class or explicitly bound to an object, it checks members of that object (`this`), following MRO and respecting visibility.
|
||||
4. **Caller environment**: Falls back to the calling context (e.g., the caller's `this` or local variables).
|
||||
5. **Global/Module fallbacks**: Final check for module-level constants and global functions.
|
||||
|
||||
Implications:
|
||||
- Global helpers like `delay(ms)` and `yield()` must be imported/known at compile time.
|
||||
- If you need dynamic access, use explicit helpers (e.g., `dynamic { ... }`) rather than relying on scope resolution.
|
||||
- Outer locals (e.g., `counter`) stay visible across suspension points.
|
||||
- Global helpers like `delay(ms)` and `yield()` are available from inside closures.
|
||||
- If you write your own async helpers, execute user lambdas under `ClosureScope(callScope, capturedCreatorScope)` and avoid manual ancestry walking.

# Scopes and Closures: resolution and safety
|
||||
|
||||
Attention to AI: name lookup in runtime `Scope` is legacy. The bytecode compiler uses **compile-time name/member resolution only**.
|
||||
This page documents how name resolution works with `ClosureScope`, how to avoid recursion pitfalls, and how to safely capture and execute callbacks that need access to outer locals.
|
||||
|
||||
This page documents the **current** rules: static name resolution, closure captures, and the limited role of runtime `Scope` in Kotlin interop and explicit dynamic helpers.
|
||||
## Why this matters
|
||||
Name lookup across nested scopes and closures can accidentally form recursive resolution paths or hide expected symbols (outer locals, module/global functions). The rules below ensure predictable resolution and prevent infinite recursion.
|
||||
|
||||
## Current rules (bytecode compiler)

- **All names resolve at compile time**: locals, parameters, captures, members, imports, and module globals must be known when compiling. Missing symbols are compile-time errors.
|
||||
- **No runtime fallbacks**: there is no dynamic name lookup, no fallback opcodes, and no “search parent scopes” at runtime for missing names.
|
||||
- **Object members on unknown types only**: `toString`, `toInspectString`, `let`, `also`, `apply`, `run` are allowed on unknown types; all other members require a statically known receiver type or an explicit cast.
|
||||
- **Closures capture slots**: lambdas and nested functions capture **frame slots** directly. Captures are resolved at compile time and compiled to slot references.
|
||||
- **Scope is a reflection facade**: `Scope` is used only for Kotlin interop or explicit dynamic helpers. It must **not** be used for general symbol resolution in compiled Lyng code.
|
||||
## Resolution order in ClosureScope
|
||||
When evaluating an identifier `name` inside a closure, `ClosureScope.get(name)` resolves in this order:
|
||||
|
||||
## Explicit dynamic access (opt-in only)
|
||||
Dynamic name access is available only via explicit helpers (e.g., `dynamic { get { name -> ... } }`). It is **not** a fallback for normal member or variable access.
|
||||
1. **Current frame locals and arguments**: Variables defined within the current closure execution.
|
||||
2. **Captured lexical ancestry**: Outer local variables captured at the site where the closure was defined (the "lexical environment").
|
||||
3. **Captured receiver members**: If the closure was defined within a class or explicitly bound to an object, it checks members of that object (`this`). This includes both instance fields/methods and class-level static members, following the MRO (C3) and respecting visibility rules (private members are only visible if the closure was defined in their class).
|
||||
4. **Caller environment**: If not found lexically, it falls back to the calling context (e.g., the DSL's `this` or the caller's local variables).
|
||||
5. **Global/Module fallbacks**: Final check for module-level constants and global functions.
|
||||
|
||||
## Legacy interpreter behavior (reference only)
|
||||
The old runtime `Scope`-based resolution order (locals → captured → `this` → caller → globals) is obsolete for bytecode compilation. Keep it only for legacy interpreter paths and tooling that explicitly opts into it.
|
||||
This ensures that closures primarily interact with their defining environment (lexical capture) while still being able to participate in DSL-style calling contexts.
|
||||
|
||||
## Use raw‑chain helpers for ancestry walks
|
||||
When authoring new scope types or advanced lookups, avoid calling virtual `get` while walking parents. Instead, use the non‑dispatch helpers on `Scope`:
|
||||
|
||||
- `chainLookupIgnoreClosure(name)`
|
||||
- Walk raw `parent` chain and check only per‑frame locals/bindings/slots.
|
||||
- Ignores overridden `get` (e.g., in `ClosureScope`). Cycle‑safe.
|
||||
- `chainLookupWithMembers(name)`
|
||||
- Like above, but after locals/bindings it also checks each frame’s `thisObj` members.
|
||||
- Ignores overridden `get`. Cycle‑safe.
|
||||
- `baseGetIgnoreClosure(name)`
|
||||
- For the current frame only: check locals/bindings, then walk raw parents (locals/bindings), then fallback to this frame’s `thisObj` members.
|
||||
|
||||
These helpers avoid ping‑pong recursion and make structural cycles harmless (lookups terminate).
|
||||
|
||||
## Preventing structural cycles
|
||||
- Don’t construct parent chains that can point back to a descendant.
|
||||
- A debug‑time guard throws if assigning a parent would create a cycle; keep it enabled for development builds.
|
||||
- Even with a cycle, chain helpers break out via a small `visited` set keyed by `frameId`.
|
||||
|
||||
## Capturing lexical environments for callbacks
|
||||
For dynamic objects or custom builders, capture the creator’s lexical scope so callbacks can see outer locals/parameters:
|
||||
|
||||
1. Use `snapshotForClosure()` on the caller scope to capture locals/bindings/slots and parent.
|
||||
2. Store this snapshot and run callbacks under `ClosureScope(callScope, captured)`.
|
||||
|
||||
Kotlin sketch:
|
||||
```kotlin
|
||||
val captured = scope.snapshotForClosure()
|
||||
val execScope = ClosureScope(currentCallScope, captured)
|
||||
callback.execute(execScope)
|
||||
```
|
||||
|
||||
This ensures expressions like `contractName` used inside dynamic `get { name -> ... }` resolve to outer variables defined at the creation site.
|
||||
|
||||
## Closures in coroutines (launch/flow)
|
||||
- The closure frame still prioritizes its own locals/args.
|
||||
- Outer locals declared before suspension points remain visible through slot‑aware ancestry lookups.
|
||||
- Global functions like `delay(ms)` and `yield()` are resolved via module/root fallbacks from within closures.
|
||||
|
||||
Tip: If a closure unexpectedly cannot see an outer local, check whether an intermediate runtime helper introduced an extra call frame; the built‑in lookup already traverses caller ancestry, so prefer the standard helpers rather than custom dispatch.
|
||||
|
||||
## Local variable references and missing symbols
|
||||
- Unqualified identifier resolution first prefers locals/bindings/slots before falling back to `this` members.
|
||||
- If neither locals nor members contain the symbol, missing field lookups map to `SymbolNotFound` (compatibility alias for `SymbolNotDefinedException`).
|
||||
|
||||
## Performance notes
|
||||
- The `visited` sets used for cycle detection are tiny and short‑lived; in typical scripts the overhead is negligible.
|
||||
- If profiling shows hotspots, consider limiting ancestry depth in your custom helpers or using small fixed arrays instead of hash sets—only for extremely hot code paths.
|
||||
|
||||
## Practical Example: `cached`
|
||||
|
||||
The `cached` function (defined in `lyng.stdlib`) is a classic example of using closures to maintain state. It wraps a builder into a zero-argument function that computes once and remembers the result:
|
||||
|
||||
```lyng
|
||||
fun cached(builder) {
|
||||
var calculated = false
|
||||
var value = null
|
||||
{ // This lambda captures `calculated`, `value`, and `builder`
|
||||
if( !calculated ) {
|
||||
value = builder()
|
||||
calculated = true
|
||||
}
|
||||
value
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Because Lyng now correctly isolates closures for each evaluation of a lambda literal, using `cached` inside a class instance works as expected: each instance maintains its own private `calculated` and `value` state, even if they share the same property declaration.
|
||||
|
||||
## Dos and Don’ts
|
||||
- Do use `chainLookupIgnoreClosure` / `chainLookupWithMembers` for ancestry traversals.
|
||||
- Do maintain the resolution order above for predictable behavior.
|
||||
- Don’t call virtual `get` while walking parents; it risks recursion across scope types.
|
||||
- Don’t attach instance scopes to transient/pool frames; bind to a stable parent scope instead.

## Nullability

Nullability is part of the type. `String` is non-null, `String?` is nullable. Use `!!` to assert non-null and throw

# Types and inference
|
||||
|
||||
Lyng uses Kotlin-style static types with inference. You can always write explicit types, but in most places the compiler
|
||||
can infer them from literals, defaults, and flow analysis.
|
||||
|
||||
## Type annotations
|
||||
|
||||
Use `:` to specify a type:
|
||||
|
||||
var x: Int = 10
|
||||
val label: String = "count"
|
||||
fun clamp(x: Int, min: Int, max: Int): Int { ... }
|
||||
|
||||
`Object` is the top type. If you omit a type and there is no default value, the parameter is `Object` by default:
|
||||
|
||||
fun show(x) { println(x) } // x is Object
|
||||
|
||||
For nullable types, add `?`:
|
||||
|
||||
fun showMaybe(x: Object?) { ... }
|
||||
fun parseInt(s: String?): Int? { ... }
|
||||
|
||||
There is also a nullable shorthand for untyped parameters and constructor args: `x?` means `x: Object?`.
|
||||
It cannot be combined with an explicit type annotation.
|
||||
|
||||
class A(x?) { ... } // x: Object?
|
||||
fun f(x?) { x == null } // x: Object?
|
||||
|
||||
Type aliases name type expressions and can be generic:
|
||||
|
||||
type Num = Int | Real
|
||||
type Maybe<T> = T?
|
||||
|
||||
Aliases expand to their underlying type expressions. See `docs/generics.md` for details.
|
||||
|
||||
`void` is a singleton value of the class `Void`. `Void` can be used as an explicit return type:
|
||||
|
||||
fun log(msg): Void { println(msg); void }
|
||||
|
||||
`Null` is the class of `null`. It is a singleton type and mostly useful for type inference results.
|
||||
|
||||
For type expressions, you can check nullability directly:
|
||||
|
||||
T is nullable
|
||||
T !is nullable
|
||||
|
||||
This is especially useful in generic code and in `when` over a type parameter:
|
||||
|
||||
fun describe<T>(x: T): String = when (T) {
|
||||
nullable -> "nullable"
|
||||
else -> "non-null"
|
||||
}
|
||||
|
||||
## Type inference
|
||||
|
||||
The compiler infers types from:
|
||||
|
||||
- literals: `1` is `Int`, `1.0` is `Real`, `"s"` is `String`, `'c'` is `Char`
|
||||
- defaults: `fun f(x=1, name="n")` infers `x: Int`, `name: String`
|
||||
- assignments: `val x = call()` uses the return type of `call`
|
||||
- returns and branches: the result type of a block is the last expression, and if any branch is nullable,
|
||||
the inferred type becomes nullable
|
||||
- numeric ops: `Int` and `Real` stay `Int` when both sides are `Int`, and promote to `Real` on mixed arithmetic
|
||||
|
||||
Examples:
|
||||
|
||||
fun inc(x=0) = x + 1 // (Int)->Int
|
||||
fun maybe(flag) { if(flag) 1 else null } // ()->Int?
|
||||
|
||||
Function types are written as `(T1, T2, ...)->R`. You can include ellipsis in function *types* to
|
||||
express a variadic position:
|
||||
|
||||
var fmt: (String, Object...)->String
|
||||
var f: (Int, Object..., String)->Real
|
||||
var anyArgs: (...)->Int // shorthand for (Object...)->Int
|
||||
|
||||
Untyped locals are allowed, but their type is fixed on the first assignment:
|
||||
|
||||
var x
|
||||
x = 1 // x becomes Int
|
||||
x = "one" // compile-time error
|
||||
|
||||
var y = null // y is Object?
|
||||
val z = null // z is Null
|
||||
|
||||
Empty list/map literals default to `List<Object>` and `Map<Object,Object>` until a more specific type is known:
|
||||
|
||||
val xs = [] // List<Object>
|
||||
val ys: List<Int> = [] // List<Int>
|
||||
|
||||
Map literals infer key/value types from entries; named keys are `String`. See `docs/generics.md` for details.
|
||||
|
||||
## Flow analysis
|
||||
|
||||
Lyng uses flow analysis to narrow types inside branches:
|
||||
|
||||
fun len(x: String?): Int {
|
||||
if( x == null ) return 0
|
||||
// x is String (non-null) in this branch
|
||||
return x.length
|
||||
}
|
||||
|
||||
`is` checks and `when` branches also narrow types:
|
||||
|
||||
fun kind(x: Object) {
|
||||
if( x is Int ) return "int"
|
||||
if( x is String ) return "string"
|
||||
return "other"
|
||||
}
|
||||
|
||||
Narrowing is local to the branch; after the branch, the original type is restored.
|
||||
|
||||
## Casts and unknown types
|
||||
|
||||
Use `as` for explicit casts. The compiler inserts casts only when it can be valid and necessary. If a cast fails at
|
||||
runtime, it throws `ClassCastException`. If the value is nullable, `as T` implies a non-null assertion.
|
||||
|
||||
Member access is resolved at compile time. Only members of `Object` are available on unknown types; non-Object members
|
||||
require an explicit cast:
|
||||
|
||||
fun f(x) { // x is Object
|
||||
x.toString() // ok (Object member)
|
||||
x.size() // compile-time error
|
||||
(x as List).size() // ok
|
||||
}
|
||||
|
||||
This avoids runtime name-resolution fallbacks; all symbols must be known at compile time.
|
||||
|
||||
## Generics and bounds
|
||||
|
||||
Generic parameters are declared with `<...>`:
|
||||
|
||||
fun id<T>(x: T): T = x
|
||||
class Box<T>(val value: T)
|
||||
|
||||
Bounds use `:` and can combine with `&` (intersection) and `|` (union):
|
||||
|
||||
fun sum<T: Int | Real>(x: T, y: T) = x + y
|
||||
class Named<T: Iterable & Comparable>(val data: T)
|
||||
|
||||
Type arguments are usually inferred from call sites:
|
||||
|
||||
val b = Box(10) // Box<Int>
|
||||
val s = id("ok") // T is String
|
||||
|
||||
See [Generics and type expressions](generics.md) for bounds, unions/intersections, and type-checking rules.
|
||||
|
||||
## Variance
|
||||
|
||||
Generic types are invariant by default, so `List<Int>` is not a `List<Object>`.
|
||||
Use declaration-site variance when you need it:
|
||||
|
||||
class Source<out T>(val value: T)
|
||||
class Sink<in T> { fun accept(x: T) { ... } }
|
||||
|
||||
`out` makes the type covariant (only produced), `in` makes it contravariant (only consumed).

# Wasm generation hang in wasmJs browser tests
|
||||
|
||||
## Summary
|
||||
The wasmJs browser test runner hung after commit 5f819dc. The root cause was invalid WebAssembly generated by the Kotlin/Wasm backend when certain compiler paths emitted suspend lambdas for `Statement` execution. The invalid module failed to instantiate in the browser, and Karma kept the browser connected but never ran tests.
|
||||
|
||||
## Symptoms
|
||||
- `:lynglib:wasmJsBrowserTest` hangs indefinitely in ChromeHeadless.
|
||||
- `:lynglib:wasmJsNodeTest` fails with a WebAssembly compile error similar to:
|
||||
- `struct.set expected type (ref null XXXX), found global.get of type (ref null YYYY)`
|
||||
- The failing function name in the wasm name section looks like:
|
||||
- `net.sergeych.lyng.$invokeCOROUTINE$.doResume`
|
||||
|
||||
## Root cause
|
||||
The delegation/var-declaration changes introduced compiler-generated suspend lambdas inside `Statement` construction (e.g., `statement { ... }` wrappers). Kotlin/Wasm generates extra coroutine state for those suspend lambdas, which in this case produced invalid wasm IR (mismatched GC reference types). The browser loader then waits forever because the module fails to instantiate.
|
||||
|
||||
## Fix
|
||||
Avoid suspend-lambda `Statement` construction in compiler code paths. Replace `statement { ... }` and other anonymous suspend lambdas with explicit `object : Statement()` implementations and move logic into `override suspend fun execute(...)`. This keeps the resulting wasm IR valid while preserving behavior.
|
||||
|
||||
## Where it was fixed
|
||||
- `lynglib/src/commonMain/kotlin/net/sergeych/lyng/Compiler.kt`
|
||||
- `lynglib/src/commonMain/kotlin/net/sergeych/lyng/Scope.kt`
|
||||
|
||||
## Verification
|
||||
- `./gradlew :lynglib:wasmJsNodeTest --info`
|
||||
- `./gradlew :lynglib:wasmJsBrowserTest --info`
|
||||
|
||||
Both tests finish quickly after the change.

### Nested Declarations and Lifted Enums
|
||||
You can now declare classes, objects, enums, and type aliases inside another class. These nested declarations live in the class namespace (no outer instance capture) and are accessed with a qualifier.
|
||||
|
||||
```lyng
|
||||
class A {
|
||||
class B(x?)
|
||||
object Inner { val foo = "bar" }

||||
enum E* { One, Two }

assertEquals(A.Inner.foo, "bar")
|
||||
assertEquals(A.One, A.E.One)
|
||||
```
|
||||
|
||||
The `*` on `enum E*` lifts entries into the enclosing class namespace (compile-time error on ambiguity).
|
||||
|
||||
### Object Expressions
|
||||
You can now create anonymous objects that inherit from classes or interfaces using the `object : Base { ... }` syntax. These expressions capture their lexical scope and support multiple inheritance.

### Kotlin API: Exception Handling
|
||||
The `Obj.getLyngExceptionMessageWithStackTrace()` extension method has been added to simplify retrieving detailed error information from Lyng exception objects in Kotlin. Additionally, `getLyngExceptionMessage()` and `raiseAsExecutionError()` now accept an optional `Scope`, making it easier to use them when a scope is not immediately available.
|
||||
|
||||
### Kotlin API: Bridge Reflection and Class Binding (Preferred Extensions)
|
||||
Lyng now provides a public Kotlin reflection bridge and a Lyng‑first class binding workflow. This is the **preferred** way to write Kotlin extensions and library integrations:
|
||||
|
||||
- **Bridge resolver**: explicit handles for values, vars, and callables with predictable lookup rules.
|
||||
- **Class bridge binding**: declare extern surfaces in Lyng (`extern` members, or members inside `extern class/object`) and bind the implementations in Kotlin before the first instance is created.
|
||||
- **Extern declaration rule**: `extern class` / `extern object` are declaration-only; all members in their bodies are implicitly extern.

# What's New in Lyng 1.3 (vs 1.2.* / master)
|
||||
|
||||
This is a programmer-focused summary of what changed since the 1.2.* line on `master`. It highlights new language and type-system features, runtime/IDE improvements, and how to migrate code safely.
|
||||
|
||||
## Highlights
|
||||
|
||||
- Generics are now a first-class part of the type system, with bounds, variance, unions, and intersections.
|
||||
- Type aliases and type-expression checks (`T1 is T2`, `A in T`) enable richer static modeling.
|
||||
- Nested declarations inside classes, plus lifted enum entries via `enum E*`.
|
||||
- Stepped ranges (`step`) including iterable open-ended and real ranges.
|
||||
- Runtime and compiler speedups: more bytecode coverage, direct slot access, call-site caching.
|
||||
|
||||
## Language and type system
|
||||
|
||||
### Generics, bounds, and variance
|
||||
|
||||
You can declare generic functions/classes with `<...>`, restrict them with bounds, and control variance.
|
||||
|
||||
```lyng
|
||||
fun id<T>(x: T): T = x
|
||||
class Box<out T>(val value: T)
|
||||
|
||||
fun sum<T: Int | Real>(x: T, y: T) = x + y
|
||||
class Named<T: Iterable & Comparable>(val data: T)
|
||||
```
|
||||
|
||||
### Type aliases and type expressions
|
||||
|
||||
Type aliases can name any type expression, including unions and intersections.
|
||||
|
||||
```lyng
|
||||
type Num = Int | Real
|
||||
type Maybe<T> = T?
|
||||
```
|
||||
|
||||
Type expressions can be checked directly:
|
||||
|
||||
```lyng
|
||||
fun f<T>(xs: List<T>) {
|
||||
assert( T is Int | String | Bool ) // type-subset check
|
||||
assert( Int in T ) // same relation as `Int is T`
|
||||
}
|
||||
```
|
||||
|
||||
Value checks remain `x is T`. Type expression equality uses `==` and is structural.
|
||||
|
||||
### Nullable shorthand for parameters
|
||||
|
||||
Untyped parameters and constructor args can use `x?` as shorthand for `x: Object?`:
|
||||
|
||||
```lyng
|
||||
class A(x?) { ... }
|
||||
fun f(x?) { x == null }
|
||||
```
|
||||
|
||||
### List/map literal inference
|
||||
|
||||
The compiler now infers element and key/value types from literals and spreads. Mixed element types produce unions.
|
||||
|
||||
```lyng
|
||||
val a = [1, 2, 3] // List<Int>
|
||||
val b = [1, "two", true] // List<Int | String | Bool>
|
||||
val m = { "a": 1, "b": "x" } // Map<String, Int | String>
|
||||
```
|
||||
|
||||
### Compile-time member access only
|
||||
|
||||
Member access is resolved at compile time. On unknown types, only `Object` members are visible; other members require an explicit cast.
|
||||
|
||||
```lyng
|
||||
fun f(x) { // x: Object
|
||||
x.toString() // ok
|
||||
x.size() // compile-time error
|
||||
(x as List).size()
|
||||
}
|
||||
```
|
||||
|
||||
This removes runtime name-resolution fallbacks and makes errors deterministic.
|
||||
|
||||
### Nested declarations and lifted enums
|
||||
|
||||
Classes, objects, enums, and type aliases can be declared inside another class and accessed by qualifier. Enums can lift entries into the outer namespace with `*`.
|
||||
|
||||
```lyng
|
||||
class A {
|
||||
class B(x?)
|
||||
object Inner { val foo = "bar" }
|
||||
type Alias = B
|
||||
enum E* { One, Two }
|
||||
}
|
||||
|
||||
val b = A.B()
|
||||
assertEquals(A.One, A.E.One)
|
||||
```
|
||||
|
||||
### Stepped ranges
|
||||
|
||||
Ranges now support `step`, and open-ended/real ranges are iterable only with an explicit step.
|
||||
|
||||
```lyng
|
||||
(1..5 step 2).toList() // [1,3,5]
|
||||
(0.0..1.0 step 0.25).toList() // [0,0.25,0.5,0.75,1.0]
|
||||
(0.. step 1).take(3).toList() // [0,1,2]
|
||||
```
|
||||
|
||||
## Tooling and performance
|
||||
|
||||
- Bytecode compiler/VM coverage expanded (loops, expressions, calls), improving execution speed and consistency.
|
||||
- Direct frame-slot access and scoped slot addressing reduce lookup overhead, including in closures.
|
||||
- Call-site caching and numeric fast paths reduce hot-loop overhead.
|
||||
- IDE tooling updated for the new type system and nested declarations; MiniAst-based completion work continues.
|
||||
|
||||
## Migration guide (from 1.2.*)
|
||||
|
||||
1) Replace dynamic member access on unknown types
|
||||
- If you relied on runtime name resolution, add explicit casts or annotate types so the compiler can resolve members.
|
||||
|
||||
2) Adopt new type-system constructs where helpful
|
||||
- Consider `type` aliases for complex unions/intersections.
|
||||
- Prefer generic signatures over `Object` when the API is parametric.
|
||||
|
||||
3) Update range iteration where needed
|
||||
- Use `step` for open-ended or real ranges you want to iterate.
|
||||
|
||||
4) Nullable shorthand is optional
|
||||
- If you used untyped nullable params, you can keep `x` (Object) or switch to `x?` (Object?) for clarity.

# What's New in Lyng 1.5 (vs 1.3.* / master)
|
||||
|
||||
This document summarizes the significant changes and new features introduced in the 1.5 development cycle.
|
||||
|
||||
## Principal changes
|
||||
|
||||
### JIT compiler and compile-time types and symbols.
|
||||
|
||||
This major improvement gives the following big advantages:
|
||||
|
||||
- **Blazing Fast execution**: several times faster! (three to six times speedup in different scenarios).
|
||||
- **Better IDE support**: autocompletion, early error detection, types check.
|
||||
- **Error safety**: all symbols and types are checked at bound at compile-time. Many errors are detected earlier. Also, no risk that external or caller code would shadow some internally used symbols (especially in closures and inheritance).
|
||||
|
||||
In particular, it means no slow and flaky runtime lookups. Once compiled, code guarantees that it will always call the symbol known at compile-time; runtime name lookup though does not guarantee it and can be source of hard to trace bugs.
|
||||
|
||||
### New stable API to create Kotlin extensions
|
||||
|
||||
The API is fixed and will be kept with further Lyng core changes. It is now the recommended way to write Lyng extensions in Kotlin. It is much simpler and more elegant than the internal one. See [Kotlin Bridge Binding](../notes/kotlin_bridge_binding.md).
|
||||
|
||||
Extern declaration clarification:
|
||||
- `extern class` / `extern object` are pure extern surfaces.
|
||||
- Members inside them are implicitly extern (`extern` on a member is optional/redundant).
|
||||
- Lyng method/property bodies for these declarations should be implemented as extensions instead.
|
||||
|
||||
### Smart types system
|
||||
|
||||
- **Deep inference**: The compiler analyzes types of symbols along the execution path and in many cases eliminates unnecessary casts or type specifications.
|
||||
- **Union and intersection types**: `A & B`, `A | B`.
|
||||
- **Generics**: Generic types are first-class citizens with support for [bounds and variance](generics.md). Type params are erased by default and are reified only when needed (e.g., `T::class`, `T is ...`, `as T`, or in extern-facing APIs), which enables checks like `A in T` when `T` is reified.
|
||||
- **Inner classes and enums**: Full support for nested declarations, including [Enums with lifting](OOP.md#lifted-enum-entries).
|
||||
|
||||
## Other highlights
|
||||
|
||||
- **The `return` Statement**: Added support for local and non-local returns using labels.
|
||||
- **Abstract Classes and Interfaces**: Full support for `abstract` members and the `interface` keyword.
|
||||
- **Singleton Objects**: Define singletons using the `object` keyword or use anonymous object expressions.
|
||||
- **Multiple Inheritance**: Enhanced multi-inheritance with predictable [C3 MRO resolution](OOP.md#multiple-inheritance-and-mro).
|
||||
- **Unified Delegation**: Powerful delegation model for `val`, `var`, and `fun` members. See [Delegation](delegation.md).
|
||||
- **Class Properties with Accessors**: Define `val` and `var` properties with custom `get()` and `set()`.
|
||||
- **Restricted Setter Visibility**: Use `private set` and `protected set` on fields and properties.
|
||||
- **Late-initialized `val`**: Support for `val` fields that are initialized in `init` blocks or class bodies.
|
||||
- **Transient Members**: Use `@Transient` to exclude members from serialization and equality checks.
|
||||
- **Named Arguments and Splats**: Improved call-site readability with `name: value` and map-based splats.
|
||||
- **Refined Visibility**: Improved `protected` access and `closed` modifier for better encapsulation.
|
||||
|
||||
## Language Features
|
||||
|
||||
### The `return` Statement
|
||||
You can now exit from the innermost enclosing callable (function or lambda) using `return`. Lyng also supports non-local returns to outer scopes using labels. See [Return Statement](return_statement.md).
|
||||
|
||||
```lyng
|
||||
fun findFirst<T>(list: Iterable<T>, predicate: (T)->Bool): T? {
|
||||
list.forEach {
|
||||
if (predicate(it)) return@findFirst it
|
||||
}
|
||||
null
|
||||
}
|
||||
```
|
||||
|
||||
### Abstract Classes and Interfaces
|
||||
Lyng now supports the `abstract` modifier for classes and their members. `interface` is introduced as a synonym for `abstract class`, allowing for rich multi-inheritance patterns.
|
||||
|
||||
```lyng
|
||||
interface Shape {
|
||||
abstract val area: Real
|
||||
fun describe() = "Area: %g"(area)
|
||||
}
|
||||
|
||||
class Circle(val radius: Real) : Shape {
|
||||
override val area get = Math.PI * radius * radius
|
||||
}
|
||||
```
|
||||
|
||||
### Class Properties with Accessors
|
||||
Properties can now have custom getters and setters. They do not have automatic backing fields, making them perfect for computed values or delegation.
|
||||
|
||||
```lyng
|
||||
class Rectangle(var width: Real, var height: Real) {
|
||||
val area: Real get() = width * height
|
||||
|
||||
var squareSize: Real
|
||||
get() = area
|
||||
set(v) {
|
||||
width = sqrt(v)
|
||||
height = width
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Singleton Objects
|
||||
Declare singletons or anonymous objects easily.
|
||||
|
||||
```lyng
|
||||
object Database {
|
||||
val connection = "connected"
|
||||
}
|
||||
|
||||
val runner = object : Runnable {
|
||||
override fun run() = println("Running!")
|
||||
}
|
||||
```
|
||||
|
||||
### Named Arguments and Named Splats
|
||||
Improve call-site clarity by specifying argument names. You can also expand a Map into named arguments using the splat operator.
|
||||
|
||||
```lyng
|
||||
fun configure(timeout: Int, retry: Int = 3) { ... }
|
||||
|
||||
configure(timeout: 5000, retry: 5)
|
||||
val options = Map("timeout": 1000, "retry": 1)
|
||||
configure(...options)
|
||||
```
|
||||
|
||||
### Modern Operators
|
||||
The `?=` operator allows for concise "assign if null" logic.
|
||||
|
||||
```lyng
|
||||
var cache: Map? = null
|
||||
cache ?= Map("status": "ok") // Only assigns if cache is null
|
||||
```
|
||||
|
||||
## Tooling and IDE
|
||||
|
||||
- **IDEA Plugin**: Significant improvements to autocompletion, documentation tooltips, and natural language support (Grazie integration).
|
||||
- **CLI**: The `lyng fmt` command is now a first-class tool for formatting code with various options like `--check` and `--in-place`.
|
||||
- **Performance**: Ongoing optimizations in the bytecode VM and compiler for faster execution and smaller footprint.
|
||||
|
||||
## Standard Library
|
||||
- **`with(self, block)`**: Scoped execution with a dedicated `self`.
|
||||
- **`clamp(value, min, max)`**: Easily restrict values to a range.
|
||||
|
||||
## Migration Guide (from 1.3.*)
|
||||
|
||||
1. **Check Visibility**: Refined `protected` and `private` rules may catch previously undetected invalid accesses.
|
||||
2. **Override Keyword**: Ensure all members that override ancestor declarations are marked with the `override` keyword (now mandatory).
|
||||
3. **Return in Shorthand**: Remember that `return` is forbidden in `=` shorthand functions; use block syntax if you need early exit.
|
||||
4. **Empty Map Literals**: Use `Map()` or `{:}` for empty maps, as `{}` is now strictly a block/lambda.

This is a branch with a kotlin compiler bug problem
|
||||
|
||||
The problem is: the code built for wasmJS target does not load (tests does not load),
|
||||
the runtime error shows incorrect wasm binary content; $80 AI attempt to investigate
|
||||
it results that most probable source of the bug is bad compilation of the _anonymous suspending lambda expressions_.
|
||||
|
||||
Sorry to say it is one of most used constructions in the Lyng compiler.
|
||||
|
||||
So we have to suspend wasmJS development.
