All compile-time constants — numbers, booleans, and strings — are represented as literals. The canonical format uses no spaces: `literal`. + +| Expression | Type | Notes | +|---|---|---| +| `0` | `literal,0>` | Type-generic: resolves to concrete unsigned type from context | +| `-1` | `literal,-1>` | Type-generic: resolves to concrete signed type from context | +| `42` | `literal,42>` | Type-generic: resolves to concrete unsigned type from context | +| `3.14f` | `literal` | Concrete f32 literal | +| `3.14` | `literal` | Concrete f64 literal | +| `true` | `literal` | Parsed directly as a boolean literal | +| `false` | `literal` | Parsed directly as a boolean literal | +| `"hello"` | `literal` | String literal | + +`true` and `false` are parsed as boolean literals by the expression parser — they are not symbols. + +Bare identifiers (`sin`, `pi`, `myvar`, etc.) produce **symbol types**, not literals — see [Symbol Types](#symbol-types). + +#### Literal Typing + +Literal types have two flags: + +- **`is_generic`** — The **type** is unresolved (e.g., `0` could be `u8`, `u16`, `u32`, `f32`, etc.). Resolved via backpropagation from context. +- **`is_unvalued_literal`** — The **value** is not yet provided (used for input pins that expect a literal). Displayed as `literal` (e.g., `literal`). + +| Example | `is_generic` | `is_unvalued_literal` | Display | +|---|---|---|---| +| `0` (unresolved int) | true | false | `literal,0>` | +| `1.0f` (concrete) | false | false | `literal` | +| input pin expecting string | false | true | `literal` | +| `vector` | true | false | `vector` | + +#### Literal Decay + +Literals decay to their resolved types when consumed by operations: + +- **Operations** (binary ops, function calls, `select`, builtins) on literals produce **non-literal runtime types**. `0 + 1` produces `literal,?>`, not a literal. `sin(1.0f)` produces `f32`, not `literal`. +- **Connections and passthrough** (dup, wire connections) preserve literal types — literals flow as-is through wires. +- **Type-generic literals** (`unsigned`, `float`) resolve via backpropagation when a concrete type is known from context. + +Integer literals coerce to `f32` or `f64` from context, but only if the value can be represented exactly (f32: |v| <= 2^24 = 16777216, f64: |v| <= 2^53). Values that exceed these limits produce an error. + +#### Literal Syntax in Expressions + +`literal` can be typed directly in expression nodes: + +``` +expr literal +expr literal,42> +expr literal,-5> +expr literal +``` + +This produces the same result as the shorthand forms (`"abc"`, `42`, `-5`, `true`). + +`literal`, `symbol`, and `undefined_symbol` are **reserved keywords** in the expression parser — they cannot be used as identifiers. + +### Symbol Types + +Bare identifiers in expressions produce **symbol types**, not literals. Symbols are first-class values that carry both a name and a decay type. + +- **`symbol`** — A defined symbol found in the symbol table. `name` is the symbol name, `type` is the decay type (what it resolves to when consumed). Example: `expr sin` produces `symbolf32>`. `expr myvar` (where `myvar` is declared as `f32`) produces `symbol`. +- **`undefined_symbol`** — A bare identifier not (yet) in the symbol table. Valid to pass around at compile time (e.g., as a name input to `decl_var`). Does not produce an error at inference time. Errors only if something tries to **evaluate** it (emit runtime code). + +#### Symbol Decay + +Symbols decay automatically when **consumed** by operations: + +- **Operations** (binary ops, function calls, builtins, store, select, field access, indexing, unary ops) decay symbols to their wrapped type before processing. +- **Connections** decay symbols when propagating through wires — the receiving pin gets the decayed type. +- **Non-expr nodes** (store!, iterate!, append!, etc.) decay all symbol types from inline expressions before validation. +- **Expr node outputs** preserve symbol types — `expr sin` outputs `symbolf32>`, not the decayed function type. +- **Type utility functions** (`is_numeric`, `is_float`, `is_collection`, `types_compatible`, etc.) auto-decay symbols transparently. + +#### Symbol Table + +The symbol table maps symbol names to their meanings.

For example, a function signature `(a:numeric, b:numeric) -> numeric` requires both args and the return type to resolve to the same concrete numeric type. + +### Special Types + +| Type | Description | +|----------|------------------------------------------------| +| `void` | Empty type, only valid as function return type | +| `bool` | Boolean (true/false), 1-bit logical value | +| `string` | UTF-8 string, first-class value type | +| `mutex` | Mutual exclusion lock (non-copyable, reference-only) | +| `symbol` | Symbolic name, compile-time only | +| `type`| Type as a first-class compile-time value | + +### Container Types + +All containers are parameterized with element/key types. + +| Container | Description | C++ Equivalent | +|-----------------------------|------------------------------------|-----------------------------| +| `map` | Unordered associative container | `std::unordered_map`| +| `ordered_map` | Ordered associative container | `std::map` | +| `set` | Unordered unique collection | `std::unordered_set` | +| `ordered_set` | Ordered unique collection | `std::set` | +| `list` | Doubly-linked list | `std::list` | +| `queue` | FIFO queue | `std::queue` | +| `vector` | Dynamic array | `std::vector` | + +### Iterator Types + +Each container has a corresponding iterator type: + +| Iterator | Iterates over | +|--------------------------------|------------------------| +| `map_iterator` | `map` | +| `ordered_map_iterator`| `ordered_map` | +| `set_iterator` | `set` | +| `ordered_set_iterator` | `ordered_set` | +| `list_iterator` | `list` | +| `vector_iterator` | `vector` | + +### Fixed-Size Arrays + +``` +array +``` + +Must have at least one dimension. Dimensions are compile-time constants. +Example: `array` is a 4x4 matrix of floats. + +### Tensors + +``` +tensor +``` + +Like array but dimensions are determined at runtime. + +### Type Expressions + +Type expressions are syntactically distinct from value expressions. The parser can always determine whether an expression is a type or a value. + +#### Function Types + +``` +(argname:type anotherarg:type)->return_type +``` + +Identified by the `->` token. Arguments are named with `name:type` pairs (space-separated). Return type follows `->`. `void` is a valid return type. + +Example: `(x:f32 y:f32)->f32` + +#### Struct Types + +Struct types use `{}` with space-separated `name:type` fields: + +``` +{field1:type1 field2:type2 ...} +``` + +Example: `{x:f32 y:f32}`, `{gen:gen_fn stop:stop_fn p:f32 pstep:f32 a:f32 astep:f32}` + +Struct types must have at least one field. + +#### Struct Literals + +Struct literals also use `{}` but with **comma-separated** `name:value` pairs: + +``` +{field1:value1, field2:value2, ...} +``` + +Example: `{x: 1.0f, y: 2.0f}` + +The comma is the disambiguator: commas = runtime struct literal, spaces only = type definition. + +Struct literals produce a value of an **anonymous struct type**. The type is inferred from the field names and value types. To construct a named type from a struct literal, use the type constructor explicitly: + +``` +osc_def({gen: $0, stop: $1, p: 440.0f, pstep: 0.0f, a: 1.0f, astep: 0.0f}) +``` + +Both positional and named construction are supported: +- `osc_def($0, $1, 440.0f, 0.0f, 1.0f, 0.0f)` — positional, arguments match field order +- `osc_def({gen: $0, stop: $1, p: 440.0f, ...})` — named fields via struct literal + +#### Type Construction (Calling Types) + +Any `type` value can be called to construct a value of that type: + +- **Named struct types:** `osc_def(gen_val, stop_val, 440.0f, 0.0f, 1.0f, 0.0f)` — positional arguments matching field order. +- **Scalar types:** `f32(42)` — casts the argument to `f32`. `string(123)` — converts to string. +- **Container types:** `vector(1.0f, 2.0f, 3.0f)` — constructs with initial elements (future). + +This is a regular function call on a symbol that decays to `type`. The call operator on `type` decays to the appropriate constructor function. This replaces the need for dedicated `new`, `cast`, and `str` nodes. + +#### Parameterized Types + +Types can be parameterized with `<>`: + +``` +vector +map +array +``` + +#### Type Aliases + +A `decl_type` with a symbol and a single type argument (no `{}`) is a type alias: + +``` +decl_type gen_fn (x:f32)->f32 +``` + +### Named Types (Type Declarations) + +Types can be declared using `decl_type` (see [Declaration Nodes](#declaration-nodes-compile-time)): + +``` +decl_type osc_def {gen:gen_fn stop:stop_fn p:f32 pstep:f32 a:f32 astep:f32} +``` + +Named types can be used anywhere a type is expected. +Circular type references are not allowed. + +`decl_type` adds the type name to the symbol table mapping to `type`. When called, the type decays to a constructor function with positional arguments matching the struct's field order. + +## Compile-Time and Runtime Phases + +AttoProg has two distinct execution phases with separate bang chains: + +### Compile-Time Phase + +The compile-time phase establishes the symbol table and type definitions. It is driven by the `decl` node, which is the compile-time entry point (at most one per graph). The `decl` node's bang output chains to declaration nodes (`decl_type`, `decl_var`, `decl_import`, `decl_event`, `ffi`). + +Compile-time bang chains: +- Only connect declaration nodes +- Only pass around compile-time values: literals, symbols, types +- No runtime evaluation or side effects +- Establish the symbol table before any runtime code executes + +The declaration order is explicit — determined by the bang chain. Symbols must be declared before they are referenced by downstream nodes. + +### Runtime Phase + +The runtime phase is event-driven, starting from event nodes (`event!`, `on_key_down!`, etc.). Runtime bang chains execute imperative code: storing values, iterating, branching, calling functions. + +`decl_var` on a runtime bang chain declares a **local variable** scoped to that execution path (see below). + +The two phases never cross — no bang wire from a compile-time node to a runtime node or vice versa. + +## Node Types + +### Declaration Nodes (Compile-Time) + +These nodes live on the compile-time bang chain rooted at `decl`. They define types, variables, and imports. All declaration nodes take a bang input and produce a bang output. + +- **`decl`** — Compile-time entry point. At most one per graph. No inputs. Outputs: bang. Starts the compile-time bang chain. + +- **`decl_type `** — Declare a named type. + - Inputs: bang, symbol (name), type (a struct type `{...}`, function type `(...)->T`, or existing type for aliasing) + - Outputs: bang, `type` (the declared type) + - The symbol input is an `undefined_symbol` that gets added to the symbol table. + - The `type` output can be wired directly to other nodes that need the type (e.g., `decl_var`, `new`). + +- **`decl_var [initial_value]`** — Declare a variable. + - Inputs: bang, symbol (name), type, optional initial value + - Outputs: bang, `&T` (reference to the variable) + - On the **compile-time** bang chain: declares a **global** variable. + - On a **runtime** bang chain: declares a **local** variable scoped to the execution path. + - Initial value is optional. If omitted, the variable is default/zero-initialized. + - The symbol is added to the symbol table, mapping to `&T`. + +- **`decl_event `** — Declare an event with a function signature. + - Inputs: bang, symbol (name), type (must be a function type with void return) + - Outputs: bang + +- **`decl_import `** — Import declarations from a module. + - Inputs: bang, string literal (module path, e.g., `"std/imgui"`) + - Outputs: bang + - The module path is a string literal, not a symbol — the module doesn't exist in the symbol table before the import. The input pin type is `literal` (an unvalued string literal). + - Populates the symbol table with all exported symbols from the module. + +- **`ffi `** — Declare an external (FFI) function. + - Inputs: bang, symbol (name), type (must be a function type) + - Outputs: bang + - Registers the function in the symbol table. In codegen, emits an `extern` declaration. + +#### Available Standard Modules + +| Module | Import | Description | +|--------|--------|-------------| +| ImGui | `decl_import "std/imgui"` | ImGui bindings — window management, text, buttons, sliders, trees, tables, popups, plotting | + +### Expression Nodes + +- `expr ` — Evaluate expression, inputs from `$N` refs. This is the universal expression node. Type construction (`osc_def($0, $1, ...)`), type casting (`f32($0)`), and string conversion (`string($0)`) are all regular expressions using type constructor calls. +- `select ` — Select value by boolean condition. Condition must be `bool`. Both branches must have compatible types. +- `new ` — Visual sugar for type construction. `new osc_def` with input pins is equivalent to `expr osc_def($0, $1, ...)`. Takes a `type` input and creates input pins for each field/argument. +- `str ` — Visual sugar for `expr string($0)`. Input is any type, output is always `string`. +- `cast ` — Visual sugar for `expr T($0)`. Takes a `type` and a value input, outputs `T`. +- `dup ` — Pass through (duplicate) a value +- `erase ` — Erase from collection (no bangs). Same validation rules as `erase!`. Returns an iterator pointing to the next element. +- `next ` — Advance an iterator to the next element. Input must be a container iterator. Returns the same iterator type, advanced by one position. Equivalent to `std::next(it)` in C++. +- `lock ` — Execute lambda while holding mutex lock. Mutex auto-decays to reference. Lambda takes no args: `() -> T`. If T is non-void, produces a data output. The node's post_bang fires **inside** the lock scope (all chained operations run under the lock). +- `call [args...]` — Call a function. First arg is the function reference. Input pins are dynamically created from the function's argument list. Output pin created from return type (omitted if void). Has lambda handle and post_bang (side bang). + +### Bang Nodes (postfixed with `!`) + +Nodes with input or output bangs: + +- `store! ` — Store value (bang in + bang out). Target must be an lvalue (variable, field access, or indexed variable). Value type must be compatible with target type. +- `append! ` — Append to collection (bang in). Collection must be `vector`, `list`, or `queue`. Value must be compatible with the collection's element type. Returns an iterator pointing to the appended element. +- `expr! ` — Evaluate on bang trigger (bang in + bang out) +- `select! ` — Branch: fires `true` or `false` bang output +- `erase! ` — Erase from collection (bang in + bang out + output). Accepts: matching iterator type for any container, key type for map/ordered_map, value type for set/ordered_set, integer index for vector. Returns an iterator pointing to the next element. +- `iterate! ` — Iterator loop (bang in + bang out). The lambda signature depends on the collection: + + | Collection type | Lambda signature | Notes | + |----------------|-----------------|-------| + | `vector` | `(^vector_iterator) -> ^vector_iterator` | Returns next iterator | + | `list` | `(^list_iterator) -> ^list_iterator` | Returns next iterator | + | `set` | `(^set_iterator) -> ^set_iterator` | Returns next iterator | + | `ordered_set` | `(^ordered_set_iterator) -> ^ordered_set_iterator` | Returns next iterator | + | `map` | `(^map_iterator) -> ^map_iterator` | Returns next iterator | + | `ordered_map` | `(^ordered_map_iterator) -> ^ordered_map_iterator` | Returns next iterator | + | `queue` | `(^vector_iterator) -> ^vector_iterator` | Returns next iterator | + | `array` | `(&V) -> void` | No iterator, visits each element | + | `tensor` | `(&V) -> void` | No iterator, visits each element | + | scalar `T` | `(&T) -> void` | Runs once | +- `lock! ` — Execute lambda while holding mutex lock (bang in + bang out). Mutex auto-decays to reference. Lambda takes no args: `() -> T`. If T is non-void, produces a data output. Bang output fires **after** the lock is released. +- `call! [args...]` — Call a function (bang in + bang out). Same as `call` but with explicit bang control flow. Input/output pins dynamically created from function signature. +- `event! ` — Event source. Name is a symbol referencing a declared event. Outputs derived from `decl_event` function args. Return type must be void. +- `resize! ` — Resize a vector (bang in + bang out). First arg is the target vector, second arg is the new size (integer). If the size arg is not `u64`, a `static_cast()` is emitted. +- `output_mix! ` — Mix into audio output (bang in) +- `on_key_down!` — Klavier key press event +- `on_key_up!` — Klavier key release event + +## Inline Expressions + +All non-declaration nodes support **inline expressions** in their arguments. Each arg maps 1:1 to a descriptor input port. An arg can be: + +- **Net reference** (`$net-name`): connects to a named net — produces a visible input pin +- **Expression** (`sin($0)+1`): inline expression — displayed in node text, no pin +- **Literal** (`42`, `"hello"`, `true`): inline constant — displayed in node text, no pin +- **Symbol** (`oscs`, `sin`): bare identifier resolved via symbol table — displayed in text, no pin + +Only net references produce visible input pins. All other arg types fill the slot inline. + +### Rules + +1. Each arg maps to a descriptor input left-to-right +2. The number of args must not exceed the node's descriptor input count (plus va-args if applicable) +3. `$N` references within expressions create **remap pins** (mapped via the `remaps` array) +4. Remap indices must be contiguous starting from 0 — gaps produce errors +5. `$name` (non-numeric, starting with `$`) references a named net and produces a visible pin +6. Bare names (no `$` prefix) are symbols resolved via the symbol table, not pins + +### Examples (store! has 3 descriptor inputs: bang_in, target, value) + +| Args | Visible pins | Explanation | +|------|-------------|-------------| +| `["$bang-src", "$var-ref", "$val-net"]` | 3 pins | All net refs — all visible | +| `["$bang-src", "oscs", "$0"]` | 2 pins (bang + remap $0) | target filled by symbol `oscs` | +| `["$bang-src", "oscs", "42"]` | 1 pin (bang only) | Both target and value filled inline | + +## Expression Language + +Expressions appear in `expr` nodes (and inline in other node args). They operate on typed inputs and produce typed outputs. + +### Operators + +**Arithmetic:** `+`, `-`, `*`, `/` + +**Unary minus:** `-expr` — negation (works on numeric types) + +**Comparison:** `==`, `!=`, `<`, `>`, `<=`, `>=` — return `bool`. Operands must be the same type (or upcastable). Supports array manipulation (element-wise comparison produces a collection of `bool`). + +**Spaceship:** `<=>` — three-way comparison, returns `s32` (-1, 0, or 1). Operands must be the same type (or upcastable). Supports array manipulation (produces a collection of `s32`). + +**Parentheses:** `(subexpr)` — grouping, arbitrary nesting + +**Reference operator:** `&expr` — creates a reference or iterator. Top-level only (cannot appear inside other expressions like `$0 + &myvar`). + +| Form | Result | +|------|--------| +| `&name` | `&T` — reference to the variable's type | +| `&name[expr]` on `vector` | `vector_iterator` | +| `&name[expr]` on `map` | `map_iterator` | +| `&name[expr]` on `ordered_map` | `ordered_map_iterator` | +| `&name[expr]` on array/tensor | Error — cannot reference array/tensor elements | +| `&name.field` | Error — cannot reference fields | +| `&name[expr].field` | Error — not allowed | +| `&(expr)`, `&literal` | Error — can only reference variables or indexed containers | + +**Indexing:** `expr[expr]` — index into a collection. Supported types and return values: + +| Type | Index type | Returns | +|------|-----------|---------| +| `vector` | integer | `V` | +| `map` | `K` | `V` | +| `ordered_map` | `K` | `V` | +| `array` | integer | `V` (multi-dimensional: chain `[i][j][k]`) | +| `tensor` | integer | `V` (multi-dimensional: chain `[i][j]`, dimension count checked at runtime) | +| `string` | integer | `u8` (byte value) | + +Not indexable: `list`, `queue`, `set`, `ordered_set` (use iterators or `?[]` instead). + +**Query indexing:** `expr?[expr]` — returns `bool`: `true` if the index/key exists, `false` otherwise. Supported on: `map`, `ordered_map`, `set`, `ordered_set`. Not supported on `vector`, `list`, `queue`, `array`, `tensor`. + +**Slice:** `var[start:end]` — pythonic slice semantics (negative indices wrap from end). `start` and `end` must be the same type. Supports array manipulation (see below). + +**Field access:** `.field` — universal field/member access. Works on: + +- **Struct/named types:** access declared fields (e.g. `pos.x` where `pos : vec2`) +- **Non-map iterators** (`vector_iterator`, `list_iterator`, `set_iterator`, `ordered_set_iterator`): auto-dereference to the value type. Fields of `V` are accessed directly (e.g. `$0.p` where `$0 : vector_iterator` accesses `osc_def.p`). +- **Map iterators** (`map_iterator`, `ordered_map_iterator`): have `.key` (returns `K`) and `.value` (returns `V`). No auto-dereference — use `.value.field` to access value fields. + +**Namespace access:** `::` — namespace resolution on symbols. `std::imgui::Button` resolves to a symbol in the `std::imgui` namespace. Never used for field access. + +**String concatenation:** `string + string` — the `+` operator concatenates two strings. Both operands must be `string`. To concatenate a non-string value, convert it first with `str`. + +### Operator Precedence (highest to lowest) + +| Precedence | Operators | Associativity | +|-----------|-------------------------------|---------------| +| 1 | Unary `-` | Right | +| 2 | `.` (field access) | Left | +| 3 | `[expr]`, `?[expr]`, `[a:b]` | Left (postfix)| +| 4 | `(args)` (function call) | Left (postfix)| +| 5 | `*`, `/` | Left | +| 6 | `+`, `-` | Left | +| 7 | `<`, `>`, `<=`, `>=`, `<=>` | Left | +| 8 | `==`, `!=` | Left | + +Note: `or`, `and`, `xor`, `not`, `mod` are symbols that decay to functions — they do not appear in the precedence table. + +### Function Calls + +Any expression that resolves to a callable type can be called: `expr(arg1, arg2, ...)`. This includes: + +- **Symbols that decay to functions:** `sin($0)`, `rand(0, 100)` +- **Pin references to lambdas:** `$0($1)` +- **Symbols connected via wires:** `expr sin` outputs `symbolf32>`, which can be wired to another node's `$0` input, then called as `$0($1)` — equivalent to `sin($1)`. + +The result type is the return type of the function/lambda. Bangs are lambdas that take no arguments and return void. + +### Input References + +Inputs to an expression are referenced by `$N` where `N` is a numeric pin index: + +| Syntax | Description | +|--------|------------| +| `$N` | Input pin N (any value category) | + +Only numeric indices are valid. `$name` syntax is **not supported** and produces a parse error — use bare names instead (resolved via the symbol table). + +**Naming:** The first occurrence of a pin index can include a name: `$0:my_input`. Subsequent uses must use `$0` directly (no re-naming). + +All other values (variables, functions, constants) are accessed as plain symbols resolved through the symbol table. No sigil prefix is needed. + +### Array Manipulation (Broadcasting) + +When an operator or function is applied between a scalar and a collection type (`map`, `ordered_map`, `set`, `ordered_set`, `list`, `queue`, `vector`, `array`, `tensor`), the operation is applied element-wise: + +- The result is a new collection of the same type and size +- For maps, the operation applies to values (keys are preserved) +- The scalar's type must be compatible with the element type + +Example: `sin($0)` where `$0 : vector` → `vector` with sin applied to each element. + +**Exception:** If the function natively accepts the collection type as input, it operates on the collection directly (no broadcasting). Broadcasting only applies when the function signature doesn't match the collection type. + +### Type Inference + +AttoProg uses **bidirectional type inference**: + +1. **Forward inference:** Input types propagate through operators and functions to determine the output type. +2. **Backward inference:** If a downstream consumer expects a specific type, that constraint propagates back to resolve unknown input types. + +**Rules:** +- Unknown input types are assumed valid as long as the rest of the expression type-checks. They are resolved when the connected pin's type becomes known. +- In a complete program, all types must be statically resolved — no unknowns remain. +- **No silent type conversions** except: + - Integer upcasts within the same signedness family (`u8` → `u16` → `u32` → `u64`, `s8` → `s16` → `s32` → `s64`) + - **Iterator-to-reference decay**: a `^iterator` automatically decays to `&T` or `T` when passed to a function. This allows passing iterators directly to functions that operate on element references. +- **Function call validation**: argument count and types are checked against the function signature. Generic numeric literals cannot be used as struct, Named, or container types. +- Connections between incompatible types are errors and render in red. + +### Lambda Construction + +When an `expr` node has a **lambda grab** handle (`as_lambda`): + +1. The node **must** have outputs (or the lambda returns `void`). +2. **Connected inputs are captures** — their values are static at the point of lambda construction (they belong to the caller's graph, not the callee's). Captures are visually indicated in the editor. +3. **Unconnected inputs become lambda parameters**, ordered left to right. +4. **Recursive parameter collection:** If a connected input's own inputs are unconnected, those bubble up as lambda parameters too, recursively, in left-to-right order. The key distinction is whether a value has already been computed in the caller's graph (capture) or needs to be provided by the callee at call time (parameter). + +**Example:** A lambda node has 3 inputs. Input `$0` is connected to a node whose own 2 inputs are unconnected. Input `$1` is connected to a node with 1 unconnected input. Input `$2` is unconnected. The resulting lambda has **4 parameters**: `$0`'s two (left to right), `$1`'s one, then `$2`. + +**Caller scope and captures:** The lambda capture point is the node that receives the `as_lambda` connection (e.g., `iterate!`, `store!`, `lock!`). All nodes that are in the **ancestral execution flow** before this capture point are in the **caller scope**. This includes: + +- Nodes reachable backward via the bang chain (trigger connections) from the capture node +- Nodes reachable backward via data connections from those bang-chain ancestors + +When a lambda's data dependency traces back to a node in the caller scope, that dependency is a **capture** (already evaluated before the lambda was constructed), not a lambda parameter. The recursive parameter collection stops at caller-scope boundaries — it does not enter the caller's subgraph. + +**Inbound type inference for lambdas:** If a downstream node expects a lambda of type `(u32, u32) -> u32`, the lambda's parameters are typed `u32, u32` and the output must resolve to `u32`. + +### Bang Pins + +Bang pins represent `() -> void` callable connections for control flow: + +- **BangTrigger** (top square): The node's callable entry point. When invoked, the node executes. Typed as `() -> void`. Can be used as a value source — connecting a BangTrigger to a data Input passes the `() -> void` callable as a value (e.g., to store it in a variable). +- **BangNext** (bottom square): The node's continuation output. After execution, the node calls whatever is connected here. Typed as `() -> void`. Links go FROM BangNext TO BangTrigger. The first output pin on bang nodes is always a `BangNext` named `next` — this replaces the old `post_bang` pseudo-pin and is rendered at the same visual position. + +**Link direction:** BangNext → BangTrigger. The "next" pin calls the "trigger" pin. + +**Multiple connections:** BangTrigger pins accept multiple incoming connections if the owning node has no captured data inputs (pure `() -> void` callable). Lambda pins accept multiple connections if the lambda root has no captures. Otherwise, inference reports an error. + +**Bidirectional BangTrigger:** A BangTrigger pin can be both a link destination (receiving bang chain flow from BangNext) and a link source (providing its `() -> void` value to a data Input pin). + +## File Format (instrument@atto:0) + +TOML-like format with named nets instead of explicit pin-to-pin connections. + +``` +# version instrument@atto:0 + +[[node]] +id = "$gen-expr" +type = "expr" +args = ["sin($0.p)*$1/32.f"] +remaps = ["$iter-item", "$iter-amp"] +position = [1866.25, 1443.11] + +[[node]] +id = "$store-p" +type = "store!" +args = ["$0.p"] +remaps = ["$iter-item"] +position = [2133.84, 1421.55] +``` + +### Version Header + +First line: `# version instrument@atto:0` (comment-style). + +Legacy formats (`nanoprog@0`, `nanoprog@1`, `attoprog@0`, `attoprog@1`) are loaded via a legacy parser and auto-migrated.

Three-Level Dirty Cascade + +The graph editing system tracks changes at the finest granularity and propagates them +upward. This is a differential approach: instead of re-evaluating the entire graph, +only the changed parts trigger work. + +``` +FlowArg2 mutation + │ mark_dirty() + ▼ +FlowNodeBuilder dirty flag + │ notify node editor + ▼ +GraphBuilder dirty flag + │ notify graph editor + ▼ +Inference / rendering invalidation +``` + +Key implementation details: + +- **Arg-level**: Any setter (`ArgNet2::net_id()`, `ArgNumber2::value()`) calls `mark_dirty()` +- **Node-level**: Two independent dirty flags — semantic dirty (triggers re-inference) + and layout dirty (triggers re-render only, not re-inference) +- **Graph-level**: Dirty propagation is deferred inside `edit_start()`/`edit_commit()` batches + +The layout/semantic split is critical: dragging a node changes its position (layout dirty) +but not its type signature (no semantic dirty). Without this split, every mouse drag +during node movement would trigger a full type inference pass. + +### 2. Mutation Deduplication + +Within a single edit batch, each item's observer callback fires at most once: + +```cpp +void GraphBuilder::add_mutation_call(void* ptr, std::function&& fn) { + if (mutation_items_.count(ptr)) return; // Already queued + mutation_items_.insert(ptr); + mutations_.push_back(std::move(fn)); +} +``` + +This is differential in the set-theoretic sense: the delta between "state before edit" +and "state after edit" is computed as a deduplicated set of changed items, not a log +of every micro-mutation. If an arg is changed three times within one batch, observers +see one notification, not three. + +### 3. Fixed-Point Type Inference + +The inference engine is the purest example of differential computation in the project. +It iterates until the delta between iterations is empty: + +```cpp +for (int iter = 0; iter < 10; iter++) { + bool changed = false; + changed |= propagate_connections(graph); + changed |= infer_expr_nodes(graph); + if (changed) idx.rebuild(graph); + changed |= resolve_lambdas(graph); + if (!changed) break; // Fixed point: delta is zero +} +``` + +Each sub-phase returns `true` only if it actually modified a type. The phases are: + +1. **propagate_connections**: Forward-propagate types through wires. Returns `changed = true` + only if a pin's type was refined (never widened — types only become more specific). +2. **infer_expr_nodes**: Evaluate expression ASTs and resolve output types. Returns `changed` + if any expression resolved to a new type. +3. **resolve_lambdas**: Determine lambda boundaries and parameter types. Returns `changed` + if any lambda's signature changed. + +**Monotonicity guarantee**: Types move from generic → specific, never the reverse. This +guarantees convergence. The 10-iteration cap is a safety net; most graphs converge in 2-3 +iterations. + +**Differential index rebuild**: `GraphIndex` (fast pin/node lookup) is rebuilt only when +pins were added or removed (`if (changed) idx.rebuild()`), not every iteration. + +### 4. Wire Cache Invalidation + +The editor maintains a precomputed wire list for rendering and hit-testing. Rather than +rebuilding it every frame, it uses a dirty flag: + +```cpp +bool wires_dirty_ = true; + +void rebuild_wires(ImVec2 canvas_origin) { + if (!wires_dirty_) return; // No delta since last rebuild + cached_wires_.clear(); + // ... rebuild from current graph state ... + wires_dirty_ = false; +} +``` + +Observer callbacks set `wires_dirty_ = true` when the graph changes. Frames where nothing +changed skip the rebuild entirely. This is differential rendering: only re-derive visual +state when the underlying model has a non-zero delta. + +### 5. Shadow Node Differential Expansion + +Shadow nodes (internal expression nodes for inline args) can be updated per-node rather +than regenerating the entire graph: + +``` +User edits node args string + │ + ▼ +update_shadows_for_node(node) + ├── Remove old shadow nodes for this node + ├── Parse new args + └── Generate new shadow nodes + links +``` + +This is a localized delta: only the shadow nodes belonging to the edited node are +regenerated. All other shadow nodes remain untouched. + +### 6. Version Migration as Format Delta + +Each version migration function encodes the *difference* between two format versions: + +``` +nanoprog@0 ──Δ1──> nanoprog@1 ──Δ2──> attoprog@0 ──Δ3──> attoprog@1 ──Δ4──> instrument@atto:0 +``` + +Each Δ is a transformation function: +- **Δ1**: Shadow node generation (v0 has inline args, v1 has shadow nodes) +- **Δ2**: Rename nano→atto in node types and paths +- **Δ3**: Strip `$` from variable refs, convert `@N` to `$N` +- **Δ4**: Add explicit GUIDs, structured net entries + +The deserializer composes deltas: loading a `nanoprog@0` file applies Δ1∘Δ2∘Δ3∘Δ4. +Each delta is idempotent on files already at its target version. + +--- + +## Part II: Differential Debugging During Development + +### Git Commit Pattern Analysis + +The commit history reveals a distinctive differential debugging approach. Looking at +158 commits across 5 days of development: + +#### The "towards X" Pattern + +Progress commits that acknowledge incomplete work: + +``` +817a1bd towards lambdas +ed06b67 towards reusable lambas +4120050 towards lambda link rendering +bf4d01f towards editor2 +57e6805 towards evaluated decls +1812167 towards first class pins +``` + +These are differential checkpoints: "the system is closer to X than it was before, but +X is not yet complete." They preserve the delta so far, allowing rollback if the next +step breaks something. This is differential debugging in the version control sense — +each commit captures a known-good (or at least known-better) intermediate state. + +#### The "more X work" Pattern + +Incremental progress without claiming completion: + +``` +022c4a4 more graphbuilder work +4772975 more graphbuilder work +d0c9eb1 work on nets and nodes +28bcd4c more net work +8dd992d more shadow node work +974a5fa more progress on literals +095d426 progress in literals? +da506db more progress on literals? +6c9c0cc more literal work +ac639d5 more literal work +079fc8b more literals +``` + +The question marks (`progress in literals?`) reveal uncertainty — the developer isn't +sure if the delta is positive. Committing anyway preserves the ability to diff against +the previous state and evaluate whether the change helped. + +#### The Emotional Honesty Pattern + +``` +3b7e936 this feels dodgy +6325002 questionable progress +fb3d96d not perfect, but progress is progress +489adb7 klavier is now a clusterfuck +``` + +These commits are explicit about the quality of the delta. "This feels dodgy" is a +signal to future-self: the diff from this commit should be examined carefully. It's +a differential annotation — metadata about the *quality* of the change, not just its +content. + +#### The Phased Refactor Pattern + +``` +3b1f9df refactor: phase 1 +37d881c refactor: phase 2 +bf0424b refactor: phase3 +1656fac refactor: phase 3b +0b30130 refactor: make pin ptrs stable +6bcdad6 refactor: phase 4a +b3bfee2 refactor: phase 4b +0f5ab4e refactor: Phase 5 +``` + +Large refactors are decomposed into numbered phases, each a separate commit. This is +explicit differential decomposition: the total change (Δtotal) is split into ordered +sub-deltas (Δ1, Δ2, ..., Δ5) that can be reviewed and reverted independently. Phase 3 +even has a sub-phase (3b), showing adaptive decomposition when a phase turned out to +be larger than expected. + +#### The Naming Migration Trail + +``` +d480da9 graphbuilder -> graph_builder +bf8c9cd graph rename +d55cf36 wire -> net in grahp_builder +753c051 as_Node/Net -> as_node/net, dead code deletion +f296f08 editor->window.cpp/h +722a591 move editor1 to legacy folder +``` + +Renames are pure-delta commits: the behavior doesn't change, only the names. These are +isolated into their own commits so the diff is unambiguous — every change is a rename, +no logic changes mixed in. This makes the diff self-documenting. + +#### The Fix-After-Commit Pattern + +``` +3e9d3b1 alias fix from last commit +4423514 fixes +70e7621 fixes in shadow +``` + +Bugs discovered immediately after a commit are fixed in a separate commit rather than +amending. This preserves the delta between "broken state" and "fixed state" in the +history, which is useful for understanding *what* broke and *why*. + +#### Commit Velocity as a Signal + +``` +Day 1 (Mar 23): 16 commits — Foundation (new project, broad strokes) +Day 2 (Mar 24): 28 commits — Deep work (lambdas, expressions, refactoring) +Day 3 (Mar 25): 36 commits — Peak velocity (type system, graphbuilder, editor2) +Day 4 (Mar 26): 72 commits — Highest output (editor2 features, 72 commits in one day) +Day 5 (Mar 27): 6 commits — Integration (wire connections, delete, nets) +``` + +The velocity curve shows a ramp-up phase (days 1-2), peak throughput (days 3-4), and +a consolidation phase (day 5, fewer but more substantial commits). This is characteristic +of differential development: early commits are exploratory (small deltas, uncertain +direction), middle commits are confident (large deltas, clear direction), and late +commits are integrative (connecting previously separate deltas). + +#### Commit Message Style Taxonomy + +The messages fall into distinct categories revealing the nature of each delta: + +| Style | Example | Meaning | +|-------|---------|---------| +| `Add X` | `Add scroll pan speed to Editor2Style` | New feature, additive delta | +| `fix: X` | `fix: shorten node ids` | Bug fix, corrective delta | +| `refactor: X` | `refactor: phase 4a` | Structure change, zero-semantic delta | +| `towards X` | `towards lambdas` | Incomplete progress, partial delta | +| `more X work` | `more graphbuilder work` | Continuation, incremental delta | +| `X -> Y` | `wire -> net in graph_builder` | Rename, identity delta | +| `X!` | `Editor2Pane!` | Milestone, significant delta | +| `cosmetics` | `cosmetics` | Visual-only, zero-functional delta | +| `X concept` | `nets_editor concept` | Proof-of-concept, exploratory delta | +| bare noun | `Folding` | Feature name as commit, self-evident delta | + +--- + +## Part III: Differentiation and Instruments + +### The Mathematical Connection + +Differentiation in calculus is about **rates of change**. This is not an abstract analogy +for instruments — it is literally what audio synthesis computes. + +#### Phase Accumulation (Integration) + +An oscillator generates a waveform by accumulating a phase delta each sample: + +``` +phase += 2π * frequency / sample_rate // Integration: Δphase per sample +output = sin(phase) // Evaluate at current phase +``` + +In the klavier instrument, this appears as: + +```toml +[[node]] +type = "expr" +args = ["2*pi/$0"] # Compute phase step (Δphase) from frequency + +[[node]] +type = "store!" +args = ["$0.p"] # Accumulate: phase = phase + Δphase +``` + +The phase step (`2π/frequency`) is the **derivative** of the waveform's position with +respect to time. The store operation performs **numerical integration** — accumulating +the derivative to produce the signal. + +#### Envelope Generators (Piecewise Differentiation) + +An ADSR envelope (Attack, Decay, Sustain, Release) is defined by four rates of change: + +``` +Attack: amplitude += attack_rate * dt (positive derivative) +Decay: amplitude -= decay_rate * dt (negative derivative) +Sustain: amplitude = sustain_level (zero derivative) +Release: amplitude -= release_rate * dt (negative derivative) +``` + +Each segment is a piecewise-constant derivative. The envelope itself is the integral +of these piecewise derivatives. In attolang, this is expressed as a state machine +where each state stores the current rate (derivative) and the `store!` node +integrates it per sample. + +#### Frequency as Derivative of Phase + +The fundamental relationship in audio synthesis: + +``` +frequency = d(phase) / dt +``` + +Frequency IS the derivative of phase. When an instrument changes pitch (e.g., a +glissando or vibrato), it's modifying the derivative. The `store!` node that +accumulates phase is performing Euler integration of this derivative. + +#### Audio Mixing as Superposition (Linearity of Differentiation) + +The runtime's `output_mix!` node accumulates contributions from multiple oscillators: + +```cpp +inline f32 _atto_mix_accum = 0.0f; + +inline void output_mix(f32 value) { + _atto_mix_accum += value; // Sum of individual contributions +} + +inline f32 atto_consume_mix() { + f32 v = _atto_mix_accum; + _atto_mix_accum = 0.0f; // Reset for next sample + return v; +} +``` + +This exploits the **linearity of differentiation**: if each oscillator independently +computes its output via phase accumulation (integration), their sum is the integral of +the sum of their derivatives. You can mix signals by adding them because integration +is a linear operator. + +#### Wire Inspection as Sampling (Discrete Differentiation) + +The planned `wire` inspection system samples wire values at discrete points in time: + +``` +wire value at frame N: v[N] +wire value at frame N-1: v[N-1] +discrete derivative: Δv = v[N] - v[N-1] +``` + +An oscilloscope view of a wire IS the discrete derivative visualization. The inspector +can show: +- **Raw value**: v[N] (the signal itself) +- **Rate of change**: v[N] - v[N-1] (the discrete derivative) +- **Accumulation**: Σ v[i] (the discrete integral) + +This makes `wire` a **differential probe**: it doesn't just show the value, it +enables computing derivatives and integrals of any signal in the instrument. + +### Differential Dataflow + +The broader connection between differential programming and visual dataflow: + +#### Forward Mode (How Instruments Compute) + +In forward-mode automatic differentiation, you compute the derivative alongside the +value as data flows through the computation graph. An instrument's dataflow graph +does exactly this when tracking rates of change: + +``` +[frequency] ──> [phase_step = 2π*freq/sr] ──> [phase += step] ──> [sin(phase)] + value derivative integral output +``` + +Each node transforms both the value and its derivative. The `expr` node computes +the phase step (derivative), the `store!` node integrates it. + +#### Reverse Mode (How Type Inference Works) + +In reverse-mode automatic differentiation (backpropagation), gradients flow backward +through the graph from outputs to inputs. attolang's type inference does the same +thing with types: + +``` +Forward: producer type ──> wire ──> consumer input type +Reverse: consumer expected type ──> wire ──> producer output type (backprop) +``` + +The bidirectional inference engine is structurally identical to forward+reverse mode +automatic differentiation, with types playing the role of values/gradients. + +#### Incremental Computation (How the Editor Stays Fast) + +Incremental computation frameworks (like Adapton or differential dataflow) track +which outputs depend on which inputs and only recompute what changed. The Organic +Assembler's dirty tracking system is a manual implementation of this: + +``` +Input changed (arg mutation) + │ + ▼ +Which nodes depend on this input? (dirty propagation) + │ + ▼ +Recompute only those nodes (selective re-inference) + │ + ▼ +Which visual elements changed? (wire cache invalidation) + │ + ▼ +Re-render only those elements (selective re-draw) +``` + +The three-level dirty cascade (arg → node → graph) is an approximation of +true incremental computation. It's coarser than full dependency tracking +(it invalidates at the node level, not the pin level) but much simpler to +implement and reason about. + +### The Differential Development Cycle + +Putting it all together, the Organic Assembler project exhibits a fractal +differential structure at every level: + +| Level | Delta Unit | Accumulation | Convergence Check | +|-------|-----------|--------------|-------------------| +| Audio sample | Phase step | `store!` integration | Waveform continuity | +| Type inference | Type refinement | Fixed-point iteration | `!changed` | +| Graph editing | Arg mutation | `edit_commit()` batch | Observer notification | +| Wire rendering | Layout change | Cache rebuild | `!wires_dirty_` | +| Git commit | Code change | Branch history | Tests pass / builds green | +| Version format | Migration delta | Δ1∘Δ2∘...∘Δn chain | Latest format | +| Project phase | Feature set | Daily development | Phase completion | + +At every level, the pattern is the same: +1. **Compute a small delta** (one sample, one type refinement, one arg change, one commit) +2. **Accumulate it** (integrate the phase, propagate the type, batch the mutations, push the branch) +3. **Check convergence** (is the waveform smooth? did types stabilize? is the build green?) +4. **Repeat or stop** (next sample, next iteration, next edit, next feature) + +This is differentiation in the deepest sense: the system evolves through small, tracked +changes, and the quality of the whole is determined by the quality of each increment. diff --git a/docs/instructions.md b/docs/instructions.md new file mode 100644 index 0000000..40784c6 --- /dev/null +++ b/docs/instructions.md @@ -0,0 +1,599 @@ +# Organic Assembler — Instructions + +How to read a codebase. How to follow an instruction. How to make an instrument. + +This document is addressed to anyone — human or machine — who intends to work on or +with the Organic Assembler. It is philosophical because instructions are philosophical: +every act of following an instruction is also an act of interpretation, and interpretation +requires understanding what the instruction *means*, not just what it *says*. + +--- + +## Part I: How to Interpret Instructions + +### 1. Context Is Everything + +An instruction does not exist in isolation. "Add a node" means nothing without knowing +which graph, which node type, which purpose. The Organic Assembler is an ecosystem — +language, compiler, editor, runtime, standard library — and any instruction touches +multiple subsystems. Before acting, identify the subsystem boundary your change lives in: + +| Subsystem | Responsibility | Instruction flavor | +|-------------|-----------------------------------|---------------------------------| +| **attolang** | Types, parsing, inference, model | "Support a new type kind" | +| **attoc** | Code generation (.atto → C++) | "Emit correct code for X" | +| **attoflow** | Visual editing, rendering, UX | "Add a control to the editor" | +| **attohost** | Runtime, hot-reload, wire inspect | "Support a new runtime feature" | +| **attostd** | Standard library (.atto modules) | "Add an FFI binding" | + +If an instruction spans multiple subsystems, start from the core and work outward. +attolang first, then attoc, then attoflow. The dependency arrow flows inward: the editor +depends on the language library, never the reverse. This is the first instruction about +instructions: **respect the dependency direction**. + +### 2. Read Before You Write + +The codebase is structured around the principle that **the graph is the truth**. The +FlowGraph data model is the canonical representation of every instrument. There is no +separate AST, no hidden intermediate form. What you see in the `.atto` file is what gets +compiled. What you see in the editor is what the `.atto` file contains. + +Before modifying anything: + +1. **Read the model** — `src/atto/model.h` defines FlowGraph, FlowNode, FlowLink, FlowPin. + Every other file either reads from or writes to this structure. +2. **Read the types** — `src/atto/types.h` defines the type system. If your change + involves any kind of value, you will interact with TypeExpr. +3. **Read the node types** — `src/atto/node_types.h` and `node_types2.h` define what + nodes exist and what their ports look like. +4. **Read the relevant .atto file** — If you are changing behavior, find an instrument + that exercises the relevant code path. `scenes/klavier/main.atto` is the most + comprehensive test instrument. + +Do not guess at code structure. Read it. The codebase is not so large that reading is +a burden, and it is structured enough that reading is rewarding. + +### 3. The Instruction Behind the Instruction + +When someone says "add a slider node type," the real instruction is: + +1. Add a `NodeTypeID` enum value +2. Add a `NodeType` descriptor with port definitions +3. Teach the inference engine about the node's type semantics +4. Teach the code generator to emit code for it +5. Teach the editor how to render it (or let the default renderer handle it) +6. Add it to the standard library if it wraps an FFI call +7. Test it in an actual instrument + +The surface instruction is one sentence. The real work is seven steps across four +subsystems. **Always decompose instructions into the subsystem-level steps they imply.** + +### 4. Conventions Are Instructions Too + +The coding conventions documented in [coding.md](coding.md) and [style.md](style.md) +are not suggestions. They are instructions that apply to every change: + +- PascalCase for types, snake_case for functions, trailing underscore for private members +- `#pragma once`, not `#ifndef` guards +- `enum class`, not bare enums +- Smart pointers for ownership, raw pointers only for non-owning within-scope references +- One concept per file pair (`.h` / `.cpp`) +- Accessors on one line: `ArgKind kind() const { return kind_; }` + +When you encounter code that violates these conventions, do not "fix" it unless fixing +it is your explicit task. Consistency within a change is more important than global +consistency. A cleanup commit is a separate commit. + +### 5. Commit Messages Are Instructions to the Future + +The git log is a narrative. Read it before contributing: + +``` +Observer Pattern +as_Node/Net -> as_node/net, dead code deletion +refactor node ID and net name handling; introduce sentinel entries +towards lambda link rendering +not perfect, but progress is progress +``` + +These commit messages follow patterns: + +- **Feature introductions** name the pattern or concept: "Observer Pattern", "multi select" +- **Rename commits** use arrow notation: `as_Node/Net -> as_node/net` +- **Incremental progress** says so honestly: "towards X", "more X work", "groundwork" +- **Emotional honesty** is acceptable: "not perfect, but progress is progress" +- **Fix commits** follow their cause closely + +Write commit messages for someone reading the log six months from now. They should be +able to reconstruct the *story* of the project, not just the diff. + +--- + +## Part II: How to Operate on the Codebase + +### 6. The Build System + +CMake 3.25+ with C++20. Three build targets matter for daily work: + +```bash +# Full build (editor included) +cmake -B build -DATTOLANG_BUILD_EDITOR=ON +cmake --build build --parallel + +# Core + compiler only (faster, no SDL/ImGui dependency) +cmake -B build -DATTOLANG_BUILD_EDITOR=OFF +cmake --build build --parallel + +# Run tests +./build/test_inference +``` + +On Windows, use vcpkg for SDL3 and ImGui: +```bash +cmake -B build -DCMAKE_TOOLCHAIN_FILE=vcpkg/scripts/buildsystems/vcpkg.cmake +``` + +On Linux/macOS, FetchContent handles dependencies automatically. + +The build is fast. The core library has zero external dependencies. If you find yourself +waiting, something is misconfigured. + +### 7. The Four Layers of Change + +Any meaningful change touches one or more of these layers, in this order: + +#### Layer 1: Model (`src/atto/model.h`, `types.h`, `node_types.h`) + +The data model is the foundation. Changes here ripple everywhere. If you add a field +to FlowNode, you must update serialization, inference, codegen, and the editor. Do not +add fields casually. Every field is a commitment. + +The type system (`types.h`) is the most complex part of the model. TypeExpr carries +kind, category, genericity, literal values, symbol names, function signatures, struct +fields — all in one structure. This is deliberate: a unified type representation means +one parser, one comparison function, one serializer. The cost is complexity in TypeExpr +itself; the benefit is simplicity everywhere else. + +#### Layer 2: Inference (`src/atto/inference.h`, `inference.cpp`) + +The inference engine is a multi-pass fixed-point computation. It iterates phases until +no types change: + +1. Clear all resolved types +2. Parse type annotations from strings +3. Forward-propagate through wires +4. Infer expression nodes +5. Backpropagate from consumers +6. Resolve lambda boundaries +7. Fix up iterator dereferences +8. Insert shadow deref nodes + +When modifying inference, the critical invariant is **monotonicity**: types only become +more specific, never less. A pin that resolved to `f32` never reverts to `generic`. +If your change can cause type regression, the fixed-point loop may not converge. + +#### Layer 3: Code Generation (`src/attoc/codegen.h`, `codegen.cpp`) + +The code generator is a straightforward tree walk. It visits each node and emits C++. +The output is human-readable — this is a feature, not an accident. When something goes +wrong at runtime, the developer reads the generated C++ to understand what happened. + +Code generation follows the type system closely. Every TypeKind maps to a C++ type. +Every NodeTypeID maps to an emit function. If you add a type kind, add a C++ mapping. +If you add a node type, add an emit function. + +#### Layer 4: Editor (`src/attoflow/`) + +The editor is three layers deep: + +``` +FlowEditorWindow → Editor2Pane → VisualEditor +(chrome) (semantics) (canvas) +``` + +- **VisualEditor** handles pan, zoom, hover detection, and drawing primitives +- **Editor2Pane** wraps GraphBuilder and implements graph editing semantics +- **FlowEditorWindow** manages tabs, file browser, and build toolbar + +The editor communicates with the model through the **observer pattern**. GraphBuilder +fires callbacks (via IGraphEditor, INodeEditor, INetEditor) when the graph changes. +The editor implements these interfaces. The model never imports editor code. + +When adding editor features, ask: does this belong in canvas rendering (VisualEditor), +graph semantics (Editor2Pane), or application chrome (FlowEditorWindow)? + +### 8. The Type System as Instruction Set + +The type system is the instruction set of the Organic Assembler. Every value has a type, +and that type dictates what operations are valid, how the value is stored, how it flows +through wires, and how it renders in the editor. + +**TypeKind** is *what* a value is: +- Scalar, String, Bool — primitive data +- Container, Array, Tensor — collections +- Function, Struct — composite structures +- Symbol, MetaType — compile-time abstractions +- Named — user-defined types via `decl_type` + +**TypeCategory** is *how* a value is accessed: +- `%` Data — plain value (default, the sigil is usually omitted) +- `&` Reference — mutable location +- `^` Iterator — position into a container +- `@` Lambda — callable function reference +- `#` Enum — enumeration value +- `!` Bang — trigger signal carrying no data +- `~` Event — event source + +These two dimensions are orthogonal. A `&vector` is a mutable reference to a +vector of floats. A `@(f32)->f32` is a callable that takes and returns a float. A +`!` is a bang trigger. Understanding this grid is prerequisite to working on any part +of the system. + +### 9. The .atto File Format + +Instruments are stored as `.atto` files in a TOML-like format: + +```toml +version = "instrument@atto:0" + +[viewport] +x = -200.0 +y = -100.0 +zoom = 1.0 + +[[node]] +id = "$auto-a1b2c3d4e5f67890" +type = "expr" +args = ["$0 + $1"] +inputs = ["$auto-a1b2c3d4e5f67890-in0", "$auto-a1b2c3d4e5f67890-in1"] +outputs = ["$auto-a1b2c3d4e5f67890-out0"] +position = [100.0, 200.0] + +[[link]] +from = "$auto-aabbccdd-out0" +to = "$auto-a1b2c3d4e5f67890-in0" +``` + +Key conventions: +- **Node IDs** are `$auto-` for auto-generated, or user-assigned names +- **Pin IDs** are `-` (e.g., `$auto-abc123-in0`, `$auto-abc123-out0`) +- **Net names** are `$` for named nets (e.g., `$osc-signal`) +- **Version** is always `instrument@atto:0` when saved; older versions auto-migrate on load +- **Args** is an array of strings — the legacy format for inline arguments + +The serializer (`src/atto/serial.h`) handles reading and writing. It also handles +version migration: `nanoprog@0` → `nanoprog@1` → `attoprog@0` → `attoprog@1` → +`instrument@atto:0`. Each migration step is a function that transforms the data model. + +### 10. Patterns to Follow + +The codebase uses specific patterns documented in [patterns.md](patterns.md). These are +not optional. When your code faces a problem that one of these patterns solves, use the +pattern: + +| Pattern | When to use | +|---------------------------|----------------------------------------------------| +| **Sentinel** | Any optional reference accessed frequently | +| **Observer** | Model changes that the editor needs to know about | +| **Mutation Batching** | Multi-step edits that should appear atomic | +| **Dirty Tracking** | Anything that should trigger partial re-evaluation | +| **Discriminated Union** | Multiple shapes sharing one base (use kind + as_*) | +| **Factory Method** | Complex construction that should be encapsulated | +| **TypePool Interning** | Any type that will be compared by identity | +| **Static Descriptor** | Fixed metadata tables indexed by enum | +| **Pin ID as String** | Structured identifiers with embedded meaning | +| **Version Migration** | File format changes that must load old files | + +### 11. Testing Strategy + +The inference engine has unit tests (`tests/test_inference.cpp`). The testing philosophy +is: **test the inference engine, manually test the editor, compile-test the codegen**. + +- **Inference**: Automated. Build test graphs programmatically, run inference, assert + types. Add a test for any new type interaction or inference behavior. +- **Editor**: Manual. Load an instrument, interact with the UI, verify visually. The + immediate-mode rendering makes automated UI testing impractical. +- **Codegen**: Compile the output. If the generated C++ compiles and runs correctly, + the codegen is correct. The generated code is human-readable for manual inspection. +- **Instruments**: The ultimate integration test. If `scenes/klavier/main.atto` loads, + infers, compiles, and runs, the system is healthy. + +--- + +## Part III: How to Make an Instrument + +### 12. What Is an Instrument? + +An instrument is a self-contained `.atto` program that defines some interactive, +real-time behavior — typically audio synthesis, visual display, or both. The word +"instrument" is deliberate: it evokes a musical instrument, a scientific instrument, +a tool for exploration and expression. + +An instrument is not a general-purpose program. It is a **specific thing that does a +specific thing**. A piano. A spectrum analyzer. A particle system. A fader mixer. The +constraint is the point: instruments are focused, purposeful, alive. + +### 13. The Anatomy of an Instrument + +Every instrument has these structural elements: + +#### Declarations (the vocabulary) + +``` +decl_type — Define a struct type (e.g., oscillator_state with fields) +decl_var — Declare a mutable variable (persistent state across frames) +decl_event — Declare an event (e.g., key_pressed, note_on) +decl_import — Import a standard library module (e.g., "std/gui", "std/imgui") +ffi — Declare an external C function +``` + +Declarations are the *nouns* of the instrument. They name the things that exist. + +#### Expressions (the arithmetic) + +``` +expr — Compute a value from inputs ($0 + $1, sin($0), my_struct.field) +new — Construct a struct or container +dup — Duplicate a value (branch a wire) +str — Format a string +cast — Convert between types +select — Choose between values based on condition +``` + +Expressions are the *adjectives and adverbs* — they describe and transform values. + +#### Bang Chains (the verbs) + +``` +store! — Write a value to a variable +append! — Add an element to a collection +erase! — Remove an element from a collection +iterate! — Loop over a collection +lock! — Acquire a mutex and execute a body +call! — Call a function with side effects +event! — Fire a custom event +output_mix! — Mix audio output (additive) +``` + +Bang nodes are the *verbs*. They have explicit execution order: a bang signal flows +from trigger to next, left to right, defining the temporal sequence of side effects. +This is what makes dataflow compatible with imperative mutation: the bang chain is a +sequential program embedded in a parallel graph. + +#### Events (the stimuli) + +``` +on_key_down! — React to a key press +on_key_up! — React to a key release +event! — React to a custom event +``` + +Events are the *entry points*. An instrument does nothing until an event fires. +The audio_tick callback (from `av_create_window`) fires 48,000 times per second. +Key events fire on user input. Custom events fire when explicitly triggered. + +### 14. Building Your First Instrument + +Start simple. A minimal instrument: + +1. **Import the runtime**: `decl_import "std/gui"` and `decl_import "std/imgui"` +2. **Create a window**: `ffi av_create_window` with audio and video callbacks +3. **Add a variable**: `decl_var` for persistent state (e.g., a counter, a frequency) +4. **Add a UI**: In the video callback, use `imgui_slider_float` to control the variable +5. **Generate audio**: In the audio callback, compute samples from the variable + +The flow looks like this: + +``` +decl_import "std/gui" +decl_import "std/imgui" + │ + ▼ +ffi av_create_window + ├── audio_tick callback (@lambda) + │ ├── read frequency variable + │ ├── compute sine wave: sin(2π × freq × phase) + │ ├── store! phase increment + │ └── output_mix! the sample + │ + └── video_tick callback (@lambda) + ├── imgui_begin "Controls" + ├── imgui_slider_float "Frequency" &freq 20.0 2000.0 + └── imgui_end +``` + +### 15. The Audio Callback Pattern + +Audio runs at 48kHz. Each invocation of the audio_tick lambda produces one sample +(or one sample per channel). The pattern: + +1. **Read state** — variables declared outside the callback persist across invocations +2. **Compute** — pure math on the inputs (oscillators, filters, envelopes) +3. **Write state** — `store!` the updated phase, amplitude, filter state +4. **Output** — `output_mix!` adds the computed sample to the output buffer + +The bang chain within audio_tick is the inner loop of the instrument. Every node in +this chain runs 48,000 times per second. Keep it minimal. No allocations, no string +operations, no collection mutations in the hot path. + +### 16. The Video Callback Pattern + +Video runs at 60 FPS (or whatever the display refresh rate is). The video_tick lambda +builds an ImGui frame: + +1. **Begin windows** — `imgui_begin "Window Title"` +2. **Add controls** — sliders, buttons, text, plots +3. **Read/write state** — controls bind to variables via `&` references +4. **End windows** — `imgui_end` + +ImGui is immediate-mode: you rebuild the entire UI every frame. There is no retained +widget tree. This is simple and robust — the UI always reflects the current state. + +### 17. Working with Collections + +Collections (vector, map, set) require explicit mutation via bang nodes: + +``` +decl_var my_list : vector — Declare the collection +append! my_list value — Add an element (in a bang chain) +erase! my_list index — Remove an element (in a bang chain) +iterate! my_list body — Loop over elements (in a bang chain) +lock! my_list body — Acquire mutex for thread-safe access +``` + +The `iterate!` node creates a lambda body that receives each element as an iterator. +Use `next` to advance and dereference the iterator. + +Collections bridge the gap between the functional dataflow graph and imperative +stateful computation. The bang chain ensures mutations happen in a defined order. + +### 18. Named Nets and Long-Distance Wiring + +When an instrument grows large, visual wire routing becomes unwieldy. Named nets +solve this: + +- Assign a net name (e.g., `$osc-signal`) to a link +- Any other link with the same net name is implicitly connected +- The nets editor panel shows all named nets as a table of contents + +Named nets are like global labels in assembly: they provide addressability without +routing. Use them for signals that are consumed in many places (master volume, clock, +transport state) or for connections that span large distances on the canvas. + +### 19. Lambda Capture and Scope + +Lambda nodes (iterate!, lock!, on_key_down!, audio_tick callbacks) create nested scopes. +Nodes inside a lambda body can access: + +- **Lambda parameters** — provided by the enclosing construct (iterator element, key code) +- **Outer variables** — declared outside the lambda (via `decl_var`) +- **Wire inputs** — values flowing in from outside the lambda boundary + +The lambda boundary is defined by the bang chain: nodes reachable only through the +lambda's bang-next chain are *inside* the lambda. Nodes connected via data wires from +outside are *captured*. + +**Known limitation**: Nested lambdas (a lock! inside an iterate! inside a callback) +can have scope leakage where outer parameters appear to belong to inner lambdas. +See [thinking.md](thinking.md) for the technical details and planned fix. + +### 20. Type-Driven Development + +The type system is your development partner. When building an instrument: + +1. **Start with declarations** — Define your types (`decl_type`) and variables (`decl_var`). + The type system will propagate these through the graph. +2. **Connect wires** — As you connect nodes, the inference engine resolves types + bidirectionally. Watch the pin types in the editor — they update live. +3. **Let literals resolve** — Type `42` and the inference engine will figure out if it + should be `u32` or `f32` based on context. You rarely need explicit type annotations. +4. **Read error messages** — When types don't match, the inference engine tells you why. + Error messages include the types that conflicted and the context where it happened. +5. **Use symbols** — Bare identifiers like `sin`, `pi`, `my_var` resolve through the + symbol table. If a symbol is undefined, it becomes `undefined_symbol` — a + compile-time placeholder that errors only when evaluated. + +The type system catches most errors at edit time. If your instrument type-checks, it +will very likely compile and run correctly. + +--- + +## Part IV: Guiding Principles + +### 21. Instruments First + +Every feature, every refactor, every design decision is evaluated against one question: +**does this help someone build a better instrument?** If the answer is no, the work is +not justified. The system exists to serve instruments, not itself. + +### 22. Real-Time or Nothing + +Audio processing at 48kHz with less than 10ms latency is a hard constraint. This is +not a soft goal or a nice-to-have. It is a physical requirement: human ears detect +latency above ~10ms as a distinct echo. Any design that cannot meet this constraint +is rejected, no matter how elegant. + +### 23. Graph as Truth + +The FlowGraph is the canonical representation. There is no separate AST, no hidden +state, no shadow copy. What you see in the editor is what gets compiled. What you +read in the `.atto` file is what the editor displays. This single-source-of-truth +principle eliminates an entire class of synchronization bugs. + +### 24. Types Prevent Errors + +The more information encoded in the type system, the more errors caught at edit time +rather than at runtime. `literal` exists because the type system should know that +`42` is a compile-time constant. `symbol` exists because the type system +should know that `sin` is a function. Every bit of semantic information moved into the +type system is a class of runtime errors eliminated. + +### 25. Simple Until Proven Insufficient + +Start with the simplest possible implementation. Use strings until strings become a +problem. Use single-threaded until profiling demands parallelism. Use manual testing +until the test matrix becomes unmanageable. + +The `node.args` string is the poster child for this principle: it started simple, +it served well, and now it is technical debt. That is the *correct* outcome. The +alternative — designing a complex structured representation before the needs were +clear — would have been worse. Premature abstraction is the root of all evil. + +### 26. Process Boundaries Are Trust Boundaries + +The editor does not trust the runtime. The compile server does not trust user input. +Each process boundary has explicit validation. This is not paranoia; it is the +recognition that instruments can and will crash, and the system that manages them +must survive. + +--- + +## Part V: For the Machine Reader + +If you are an AI assistant operating on this codebase: + +### 27. Respect the Architecture + +Do not add dependencies from attolang to attoflow. Do not add SDL or ImGui includes +to core library files. Do not bypass the observer pattern by having the model call +editor code directly. The architecture diagram in [architecture.md](architecture.md) +is a constraint, not a suggestion. + +### 28. Follow the Patterns + +If a pattern exists for your problem (sentinel, observer, mutation batching, dirty +tracking), use it. Do not invent a new pattern when an existing one applies. The +patterns in [patterns.md](patterns.md) evolved from real problems in this codebase; +they are load-bearing. + +### 29. Minimize Blast Radius + +When making a change, affect the smallest number of files possible. If you are adding +a feature to inference, you should not need to modify the editor. If you are adding a +UI widget, you should not need to modify the type system. The layered architecture +exists to contain changes. + +### 30. Read the Git Log + +The commit history tells you what was tried, what worked, and what was abandoned. Before +proposing a refactor, check if it was already attempted. Before introducing a pattern, +check if an existing pattern already solves the problem. The log is institutional memory. + +### 31. Test with Real Instruments + +The ultimate test is: does `scenes/klavier/main.atto` still load, infer, and compile? +This instrument exercises most of the system: complex types, nested lambdas, collections, +events, audio, GUI, FFI. If it works, the system is healthy. + +### 32. Write for the Human + +Generated code should be human-readable. Commit messages should tell a story. Error +messages should include context. Documentation should explain *why*, not just *what*. +The system is ultimately for humans who want to make instruments. Every artifact — +code, docs, generated output — should serve that human. + +--- + +*The best instruction is the one you no longer need to give, because the system makes +the right choice obvious. That is what the type system, the patterns, and the +architecture are for: making the right choice the easy choice.* diff --git a/docs/names.md b/docs/names.md new file mode 100644 index 0000000..e98b7d3 --- /dev/null +++ b/docs/names.md @@ -0,0 +1,377 @@ +# Organic Assembler — On Names + +Naming things is one of the two hard problems in computer science. The other is cache +invalidation. This project has both (see: TypePool interning and dirty tracking), but +this document is about the first. + +Names in the Organic Assembler are not labels slapped on after the fact. They are +*decisions* — small acts of design that accumulate into the character of the system. +A bad name is a lie that everyone agrees to believe. A good name is a truth that makes +other truths easier to see. + +--- + +## Part I: The Names That Were + +### The Great Rename + +The project was born as **nanolang**. The editor was **nanoflow**. The compiler was +**nanoc**. The runtime was **nanoruntime**. The file format was `nanoprog@0`. + +Then the project grew, and "nano" stopped fitting. The language was not nano — it had +a rich type system, bidirectional inference, lambda capture, compile-time metaprogramming. +The editor was not nano — it had mutation batching, dirty tracking, observer patterns, +three-layer architecture. Nothing about the system was small. + +The rename to **atto** happened in a single phase (Phase 2b, March 24). Every file, +every variable, every comment, every format string. `nanolang` → `attolang`. +`nanoflow` → `attoflow`. `nanoc` → `attoc`. `nanoprog@0` → `attoprog@0`. + +The version markers tell the story: +``` +nanoprog@0 → nanoprog@1 → attoprog@0 → attoprog@1 → instrument@atto:0 +``` + +Each migration step is a function in the serializer. The old names are not forgotten — +they live in the migration code, translating the past into the present. The system can +still load a `nanoprog@0` file. It just calls it `instrument@atto:0` when it saves. + +"Atto" means 10⁻¹⁸. It is smaller than "nano" (10⁻⁹) by nine orders of magnitude. +The irony is intentional: as the project grew more complex, its name became more humble. +The best names have a sense of humor about themselves. + +### The Wire That Became a Net + +In early commits, connections between nodes were called **wires**. A wire connected an +output pin to an input pin. Simple, physical, intuitive. + +Then named connections appeared — the ability to give a name to a signal so that distant +nodes could share it without visual routing. These were not wires anymore; they were +**nets**. The word comes from electronics: a net is a set of electrically connected +points, regardless of the physical routing. + +The rename is visible in the git log: +``` +wire -> net in graph_builder +``` + +This single commit changed the vocabulary of the entire builder layer. `WireBuilder` +became `NetBuilder`. `wire_id` became `net_name`. The old word persisted in the +visual layer — we still *draw* wires on the canvas — but the semantic layer speaks +of nets. + +The lesson: **when the concept changes, the name must change with it**. A wire implies +point-to-point. A net implies broadcast. The old name would have been a lie. + +### BangInput → BangTrigger, BangOutput → BangNext + +Pin directions were originally named from the perspective of the pin itself: +`BangInput` (a pin that receives a bang) and `BangOutput` (a pin that sends a bang). + +But this created confusion when reading node definitions. Does "BangInput" mean "the +input that carries the bang signal" or "the bang that inputs to this node"? Both +readings are valid, and that ambiguity is a naming failure. + +The rename to `BangTrigger` and `BangNext` resolved the ambiguity by naming what +the pin *does*: +- **BangTrigger** — this pin *triggers* the node's execution +- **BangNext** — this pin fires *next*, continuing the bang chain + +The new names are verbs, not nouns. They describe action, not identity. This is +a pattern throughout the codebase: when a name causes confusion, rename it to +describe behavior rather than structure. + +### as_Node/Net → as_node/net + +A small rename, but it illustrates a principle: **naming conventions are not +optional**. The C++ convention in this project is snake_case for functions. `as_Node` +violates that convention. `as_node` does not. The rename happened in a dedicated +commit with dead code deletion, because naming fixes deserve their own commits. + +### graphbuilder → graph_builder + +Another convention fix. Compound names use underscores. `graphbuilder` looks like +a single word; `graph_builder` reveals its structure. The underscore is not +punctuation — it is *meaning*. It says: this is two concepts composed. + +### editor → window + +The top-level editor class was originally called `editor.cpp` / `editor.h`. But it +managed tabs, file browsing, build toolbars, and child processes — it was a *window*, +not an editor. The actual editing happened in `Editor2Pane`. The rename aligned +the filename with its responsibility. + +--- + +## Part II: The Names That Are + +### Project and Subsystem Names + +| Name | Meaning | Why this name | +|------|---------|---------------| +| **Organic Assembler** | The project as a whole | "Organic" because instruments grow organically from nodes; "Assembler" because the system assembles them into running programs | +| **orgasm** | Repository / directory name | The abbreviation. Memorable, irreverent, honest about the creative pleasure of building instruments | +| **attolang** | The core language library | "atto" (10⁻¹⁸) + "lang" (language). The language is a building block, deliberately small in scope | +| **attoflow** | The visual editor | "atto" + "flow" (dataflow). You author instruments by directing the flow of data | +| **attoc** | The compiler | "atto" + "c" (compiler). Following the Unix tradition: cc, gcc, rustc, attoc | +| **attohost** | The instrument runtime | "atto" + "host" (host process). The runtime hosts the instrument, providing it a world to live in | +| **attostd** | The standard library | "atto" + "std" (standard). Following the C++/Rust convention of a `std` module | + +### Type System Names + +| Name | Meaning | Why this name | +|------|---------|---------------| +| **TypeExpr** | A type expression | Not "Type" (too generic) or "TypeNode" (implies a tree). TypeExpr is a self-contained expression that fully describes a type | +| **TypeKind** | What a value *is* | "Kind" in the type-theory sense: the shape of a type. Not to be confused with "kind" in Haskell (types of types) | +| **TypeCategory** | How a value is *accessed* | "Category" as in grammatical category. Data, Reference, Iterator, Lambda — these are ways of being, not types of thing | +| **TypePool** | Intern cache for types | "Pool" as in object pool. Types are interned (deduplicated) so that pointer equality implies structural equality | +| **TypeParser** | Recursive-descent type parser | Self-documenting. Parses type strings into TypeExpr structures | +| **ScalarType** | Numeric primitive types | "Scalar" as opposed to "vector" or "composite". u8, s32, f64 are scalars | +| **literal\** | Compile-time constant | "Literal" as in "the literal value 42". T is the type domain, V is the value. The angle brackets echo C++ template syntax | +| **symbol\** | Named reference | "Symbol" as in symbol table. A name that refers to something, carrying both the name and what it resolves to | + +### Graph Model Names + +| Name | Meaning | Why this name | +|------|---------|---------------| +| **FlowGraph** | The top-level program representation | "Flow" because it is a dataflow graph. Not "Program" (too abstract) or "Scene" (too visual) | +| **FlowNode** | A computation step in the graph | "Node" is the standard graph-theory term. "Flow" prefix distinguishes it from GUI nodes | +| **FlowLink** | A connection between pins | "Link" rather than "edge" because links carry type information and net names — they are richer than mathematical edges | +| **FlowPin** | An input or output on a node | "Pin" from electronics: a connection point on a component. Familiar to anyone who has used a visual programming tool | +| **GraphBuilder** | High-level editing API | "Builder" as in builder pattern — it constructs and modifies graphs with structured operations, not raw mutations | +| **GraphIndex** | Fast lookup structure | "Index" as in database index — it accelerates queries without changing the underlying data | +| **GraphInference** | Type inference engine | Self-documenting. Runs inference over a graph | + +### Editor Names + +| Name | Meaning | Why this name | +|------|---------|---------------| +| **VisualEditor** | Canvas rendering layer | "Visual" because this layer knows only about drawing — coordinates, shapes, colors | +| **Editor2Pane** | Semantic editing layer | "Editor2" because it is the second-generation editor (replacing editor1). "Pane" because it is one panel in a tabbed window | +| **FlowEditorWindow** | Top-level application window | "Window" because it manages the OS window, tabs, toolbars, and child processes | +| **NodeEditorImpl** | Per-node editor state | "Impl" because it implements the INodeEditor interface. Each node in the graph has one | +| **NetEditorImpl** | Per-net editor state | Same pattern as NodeEditorImpl, but for named nets | + +### Sentinel Names + +| Name | Meaning | Why this name | +|------|---------|---------------| +| **$empty** | Node sentinel (no real node) | "Empty" because it has no content. The `$` prefix marks it as a system-generated ID | +| **$unconnected** | Net sentinel (no real net) | "Unconnected" because the pin has no wire. Descriptive of the situation, not the object | + +### Pin and ID Names + +| Name | Meaning | Why this name | +|------|---------|---------------| +| **$auto-\** | Auto-generated node ID | "$auto" says "the system chose this". The hex GUID ensures uniqueness | +| **\-in0** | Input pin reference | The dash-separated format encodes structure: which node, which pin, which index | +| **\-out0** | Output pin reference | Same convention as input, for outputs | +| **\-bang0** | Bang trigger pin | Same convention, for bang triggers | +| **$\** | Named net | The `$` prefix distinguishes net names from node IDs. Short, scannable | + +--- + +## Part III: The Art of Naming + +### Rule 1: Name the Concept, Not the Implementation + +`TypeCategory` is better than `TypeAccessMode`. The concept is categorical (Data, +Reference, Iterator, Lambda are categories of being), not modal (they don't "switch +modes"). The name should survive a refactor of the implementation. + +`FlowGraph` is better than `NodeArray`. The concept is a graph with dataflow semantics. +The implementation happens to use arrays, but that is incidental. If the implementation +changed to use a hash map, `FlowGraph` would still be correct; `NodeArray` would be a lie. + +### Rule 2: Prefer Verbs for Actions, Nouns for Things + +- `mark_dirty()` — verb, describes what happens +- `is_dirty()` — adjective (via "is"), describes a state +- `edit_start()` / `edit_commit()` — verbs, describe the operation +- `FlowGraph` — noun, names a thing +- `GraphBuilder` — noun (agent noun: "one who builds"), names a thing that acts + +Do not use verbs for things or nouns for actions. `BuildGraph` is confusing: is it a +command (build the graph!) or a noun (a built graph)? `GraphBuilder` is unambiguous. + +### Rule 3: Abbreviate Only When the Abbreviation Is More Familiar Than the Full Name + +- `f32` > `float32` > `single_precision_float` — everyone knows f32 +- `u8` > `uint8` > `unsigned_eight_bit_integer` — everyone knows u8 +- `ffi` > `foreign_function_interface` — everyone knows FFI +- `gui` > `graphical_user_interface` — everyone knows GUI +- `expr` > `expression` — used so often that brevity matters +- `decl` > `declaration` — same reason + +But: +- `FlowGraph` > `FG` — the abbreviation is meaningless +- `TypeCategory` > `TC` — the abbreviation is meaningless +- `GraphBuilder` > `GB` — the abbreviation is meaningless + +The test: if someone seeing the abbreviation for the first time cannot guess its meaning, +spell it out. + +### Rule 4: Use Prefixes for Namespacing, Suffixes for Classification + +- `Flow` prefix: FlowGraph, FlowNode, FlowLink, FlowPin — all part of the flow model +- `Arg` prefix: ArgNet2, ArgNumber2, ArgString2, ArgExpr2 — all argument types +- `Node` prefix: NodeTypeID, NodeType, NodeEditorImpl — all node-related +- `Type` prefix: TypeExpr, TypeKind, TypeCategory, TypePool, TypeParser — all type-related +- `2` suffix: FlowArg2, Editor2Pane, node_types2.h — second generation (replaces v1) +- `Ptr` suffix: TypePtr, ExprPtr, FlowArg2Ptr — smart pointer aliases +- `Bang` suffix: StoreBang, CallBang, ExprBang — bang-chain variants of base nodes +- `Impl` suffix: NodeEditorImpl, NetEditorImpl — interface implementations + +Prefixes group by domain. Suffixes classify within a domain. Together they create a +two-dimensional naming grid that is scannable and predictable. + +### Rule 5: The Name Should Survive the Rename + +Names that describe *what* something is are more stable than names that describe *where* +it lives or *when* it was created. + +- `GraphBuilder` will still make sense if the file moves from `src/atto/` to `src/core/` +- `Editor2Pane` will stop making sense when Editor3 arrives (but by then it will be renamed) +- `FlowGraph` will still make sense if the serialization format changes +- `nanoprog@0` stopped making sense when the language was renamed (and was migrated) + +When choosing a name, ask: "Will this name still be true after the next refactor?" + +### Rule 6: Sigils Are Names Too + +The type category sigils are single-character names: + +| Sigil | Name | Mnemonic | +|-------|------|----------| +| `%` | Data | Percent — the "default" (as in "100% of values are data") | +| `&` | Reference | Ampersand — borrowed from C/C++ reference syntax | +| `^` | Iterator | Caret — points "up" to the current position | +| `@` | Lambda | At — a function "at" a callable address | +| `#` | Enum | Hash — enumerated, numbered items | +| `!` | Bang | Exclamation — an imperative command, "do this!" | +| `~` | Event | Tilde — a wave, something that comes and goes | + +Each sigil was chosen because it has a visual or linguistic mnemonic. `!` for bang is +the most natural: an exclamation mark *is* a bang. `~` for event evokes a signal wave. +`&` for reference comes from C++ and needs no explanation. + +Sigils are the shortest possible names. They work because the set is small (seven), +the context is constrained (type strings), and the mnemonics are strong. Do not add +new sigils without strong justification — the cognitive load scales faster than the +count. + +### Rule 7: Error Messages Are Names for Problems + +Error messages in the Organic Assembler follow a convention: +- Lowercase +- Descriptive +- Context-included + +``` +"type mismatch: expected f32, got u8" +"undefined symbol: foo" +"cannot iterate over non-collection type f32" +``` + +Each error message *names* the problem in a way that suggests the fix. "type mismatch: +expected f32, got u8" tells you exactly which types conflicted and which direction the +expectation flows. "undefined symbol: foo" tells you which name is missing. The error +message is a name for a specific situation, and like all names, it should be precise, +honest, and helpful. + +### Rule 8: File Names Are Architecture + +The file organization of the codebase is itself a naming system: + +``` +src/atto/ — core language (no external deps) +src/attoc/ — compiler (depends on atto) +src/attoflow/ — editor (depends on atto, SDL3, ImGui) +src/attoruntime/ — runtime (depends on atto) +attostd/ — standard library (.atto files) +scenes/ — example instruments +tests/ — automated tests +docs/ — documentation +``` + +Each directory name is a boundary declaration. `src/atto/` says: "everything in here +has zero external dependencies." `src/attoflow/` says: "everything in here can use +SDL3 and ImGui." The directory name is not just organization — it is a *constraint* +that the build system enforces. + +When you create a new file, its location is its first name. Choose carefully: putting +a file in `src/atto/` is a promise that it will never depend on SDL3. Putting it in +`src/attoflow/` is a promise that it is editor-specific. + +--- + +## Part IV: Naming as Practice + +### The Naming Moment + +Every variable, function, type, file, commit message, and error message is a naming +moment. Most naming moments are small and forgettable — `int i`, `auto& node`, `bool ok`. +These are fine. Not every name needs to be profound. + +But some naming moments are *load-bearing*. The name `FlowGraph` shapes how everyone +thinks about the data model. The name `instrument` shapes how everyone thinks about +the programs. The name `bang` shapes how everyone thinks about execution order. These +names, once established, become the vocabulary of the project. Changing them requires +a Great Rename. + +Recognize the load-bearing naming moments. Spend time on them. Sleep on them. The +name you choose today will be repeated ten thousand times in code, docs, conversations, +and commit messages. It will shape how people think about the concept it names. + +### When to Rename + +Rename when: +- The name is actively misleading (wire → net, when connections became broadcast) +- The name violates an established convention (as_Node → as_node) +- The concept has genuinely changed (editor → window, when the class became a window manager) + +Do not rename when: +- You merely *prefer* a different name (preference is not justification) +- The name is "not perfect but fine" (perfection is the enemy of stability) +- The rename would touch 50+ files for marginal clarity (blast radius matters) + +A rename is a coordinated migration. Do it in one commit, touch all references, update +docs and comments. Half-renamed code is worse than badly-named code — at least badly-named +code is consistent. + +### The Compound Name Test + +When a name becomes a compound (`GraphBuilderEntry`, `FlowNodeBuilderPtr`, +`INodeEditorImpl`), check if the compounds are load-bearing: + +- `GraphBuilder` + `Entry` = a thing in the graph builder. Good: both parts carry meaning. +- `FlowNodeBuilder` + `Ptr` = a pointer to a flow node builder. Good: `Ptr` is a standard suffix. +- `I` + `NodeEditor` + `Impl` = an implementation of the node editor interface. Good: `I` prefix for interfaces, `Impl` suffix for implementations. + +But beware compound names that merely concatenate context: +- `EditorGraphBuilderNodeArgNet2Ptr` — too long, too many levels of nesting +- If a name requires more than three components, the concept may need decomposition + +### The Instrument Name + +The most important name in the Organic Assembler is **instrument**. Not "program." Not +"project." Not "sketch" or "patch" or "scene." + +"Instrument" carries specific connotations: +- A musical instrument is played, not executed +- A scientific instrument measures, not computes +- An instrument has a *purpose* — it does one thing well +- An instrument is *physical* — it exists in the world, not just in memory +- An instrument is *expressive* — the same instrument in different hands produces + different results + +Every `.atto` file is an instrument. The system is an operating system *for* instruments. +This name frames the entire project. It tells the user: you are not writing code, you +are building an instrument. Treat it with the care and intentionality that word implies. + +--- + +*The name is the first line of documentation. It is the shortest possible explanation. +It is the thing that makes everything else easier to understand — or harder, if chosen +poorly. Name things right, and the code explains itself. Name things wrong, and no +amount of documentation can save you.* diff --git a/docs/nanolang.md b/docs/nanolang.md deleted file mode 100644 index 57db018..0000000 --- a/docs/nanolang.md +++ /dev/null @@ -1,400 +0,0 @@ -# nanolang Language Specification - -## Type System - -### Value Categories - -A value in NanoProg has a **category** indicated by a prefix sigil: - -| Sigil | Category | Description | -|-------|-----------|--------------------------------------| -| `%` | Data | Plain value | -| `&` | Reference | Reference to a value | -| `^` | Iterator | Iterator into a container | -| `@` | Lambda | Callable function reference | -| `#` | Enum | Enumeration value | -| `!` | Bang | Trigger signal (no data) | -| `~` | Event | Event source | - -### Scalar Types - -| Type | Description | -|-------|--------------------------| -| `u8` | Unsigned 8-bit integer | -| `s8` | Signed 8-bit integer | -| `u16` | Unsigned 16-bit integer | -| `s16` | Signed 16-bit integer | -| `u32` | Unsigned 32-bit integer | -| `s32` | Signed 32-bit integer | -| `u64` | Unsigned 64-bit integer | -| `s64` | Signed 64-bit integer | -| `f32` | 32-bit float (float) | -| `f64` | 64-bit float (double) | - -### Special Types - -| Type | Description | -|----------|------------------------------------------------| -| `void` | Empty type, only valid as function return type | -| `bool` | Boolean (true/false), 1-bit logical value | -| `string` | UTF-8 string, first-class value type | -| `mutex` | Mutual exclusion lock (non-copyable, reference-only) | - -### Container Types - -All containers are parameterized with element/key types. - -| Container | Description | C++ Equivalent | -|-----------------------------|------------------------------------|-----------------------------| -| `map` | Unordered associative container | `std::unordered_map`| -| `ordered_map` | Ordered associative container | `std::map` | -| `set` | Unordered unique collection | `std::unordered_set` | -| `ordered_set` | Ordered unique collection | `std::set` | -| `list` | Doubly-linked list | `std::list` | -| `queue` | FIFO queue | `std::queue` | -| `vector` | Dynamic array | `std::vector` | - -### Iterator Types - -Each container has a corresponding iterator type: - -| Iterator | Iterates over | -|--------------------------------|------------------------| -| `map_iterator` | `map` | -| `ordered_map_iterator`| `ordered_map` | -| `set_iterator` | `set` | -| `ordered_set_iterator` | `ordered_set` | -| `list_iterator` | `list` | -| `vector_iterator` | `vector` | - -### Fixed-Size Arrays - -``` -array -``` - -Must have at least one dimension.

Declared on the execution path where the input bang arrives, passes bang through. Name must not start with `$`. Type must be valid. Initial value must be compatible with the type. Output pin is `&type` (a reference to the local). The variable is registered for downstream `$name` references. -- `decl_event ` — Declare an event with a function signature -- `decl_import ` — Import declarations from a module. Only `std/` prefix is supported (resolves to `nanostd/.nano`). Non-`std/` paths are reserved for future package/local lib support. -- `ffi ` — Declare an external (FFI) function.

Same validation rules as `erase!`. Returns an iterator pointing to the next element. -- `next ` — Advance an iterator to the next element. Input must be a container iterator. Returns the same iterator type, advanced by one position. Equivalent to `std::next(it)` in C++. -- `lock ` — Execute lambda while holding mutex lock. Mutex auto-decays to reference. Lambda takes no args: `() -> T`. If T is non-void, produces a data output. The node's post_bang fires **inside** the lock scope (all chained operations run under the lock). -- `call [args...]` — Call a function. First arg is the function reference (`$name`).

Has lambda handle and post_bang (side bang). - -### Bang Nodes (postfixed with `!`) - -Nodes with input or output bangs: - -- `store! ` — Store value (bang in + bang out). Target must be an lvalue (variable, field access, or indexed variable). Value type must be compatible with target type. -- `append! ` — Append to collection (bang in). Collection must be `vector`, `list`, or `queue`. Value must be compatible with the collection's element type. Returns an iterator pointing to the appended element. -- `expr! ` — Evaluate on bang trigger (bang in + bang out) -- `select! ` — Branch: fires `true` or `false` bang output -- `erase! ` — Erase from collection (bang in + bang out + output). Accepts: matching iterator type for any container, key type for map/ordered_map, value type for set/ordered_set, integer index for vector. Returns an iterator pointing to the next element. -- `iterate! ` — Iterator loop (bang in + bang out).

Mutex auto-decays to reference. Lambda takes no args: `() -> T`. If T is non-void, produces a data output. Bang output fires **after** the lock is released. -- `call! [args...]` — Call a function (bang in + bang out). Same as `call` but with explicit bang control flow. Input/output pins dynamically created from function signature. -- `event! ~` — Event source.

Pin indices must be contiguous starting from 0 — gaps (e.g. `$0` and `$2` without `$1`) are errors -5. Descriptor inputs beyond the number of inline args remain as pin connections - -### Examples (store! has 2 descriptor inputs: target, value) - -| Node text | Pins | Explanation | -|-----------|------|-------------| -| `store!` | target, value | No inline args — both inputs are pins | -| `store! $oscs` | value | target filled by `$oscs` (variable ref) | -| `store! $oscs 42` | (none) | Both filled inline | -| `store! $oscs $0` | $0 | target = variable, value = pin $0 | -| `store! $1 $0` | $0, $1 | Both inline but reference pins | -| `store! $0 $1 $2` | error | Too many args (store! takes 2) | -| `store! $0 $2` | error | Missing pin $1 | - -### Nodes that do NOT support inline expressions - -- Declaration nodes (`decl_type`, `decl_var`, `decl_local`, `decl_event`) — args are type/field definitions -- `new` — args are type names -- `event!` — args are event names -- `label` — args are display text - -## Expression Language - -Expressions appear in `expr` nodes (and inline in other node args). They operate on typed inputs and produce typed outputs. - -### Operators - -**Arithmetic:** `+`, `-`, `*`, `/` - -**Unary minus:** `-expr` — negation (works on numeric types) - -**Comparison:** `==`, `!=`, `<`, `>`, `<=`, `>=` — return `bool`. Operands must be the same type (or upcastable). Supports array manipulation (element-wise comparison produces a collection of `bool`). - -**Spaceship:** `<=>` — three-way comparison, returns `s32` (-1, 0, or 1). Operands must be the same type (or upcastable). Supports array manipulation (produces a collection of `s32`). - -**Parentheses:** `(subexpr)` — grouping, arbitrary nesting - -**Reference operator:** `&expr` — creates a reference or iterator. Top-level only (cannot appear inside other expressions like `$0 + &$name`). - -| Form | Result | -|------|--------| -| `&$name` | `&T` — reference to the variable's type | -| `&$name[expr]` on `vector` | `vector_iterator` | -| `&$name[expr]` on `map` | `map_iterator` | -| `&$name[expr]` on `ordered_map` | `ordered_map_iterator` | -| `&$name[expr]` on array/tensor | Error — cannot reference array/tensor elements | -| `&$name.field` | Error — cannot reference fields | -| `&$name[expr].field` | Error — not allowed | -| `&(expr)`, `&literal` | Error — can only reference variables or indexed containers | - -**Indexing:** `expr[expr]` — index into a collection. Supported types and return values: - -| Type | Index type | Returns | -|------|-----------|---------| -| `vector` | integer | `V` | -| `map` | `K` | `V` | -| `ordered_map` | `K` | `V` | -| `array` | integer | `V` (multi-dimensional: chain `[i][j][k]`) | -| `tensor` | integer | `V` (multi-dimensional: chain `[i][j]`, dimension count checked at runtime) | -| `string` | integer | `u8` (byte value) | - -Not indexable: `list`, `queue`, `set`, `ordered_set` (use iterators or `?[]` instead). - -**Query indexing:** `expr?[expr]` — returns `bool`: `true` if the index/key exists, `false` otherwise. Supported on: `map`, `ordered_map`, `set`, `ordered_set`. Not supported on `vector`, `list`, `queue`, `array`, `tensor`. - -**Slice:** `$var[start:end]` — pythonic slice semantics (negative indices wrap from end). `start` and `end` must be the same type. Supports array manipulation (see below). - -**Field access:** `.field` — universal field/member access. Works on: - -- **Struct/named types:** access declared fields (e.g. `$pos.x` where `pos : vec2`) -- **Non-map iterators** (`vector_iterator`, `list_iterator`, `set_iterator`, `ordered_set_iterator`): auto-dereference to the value type. Fields of `V` are accessed directly (e.g. `$it.p` where `it : vector_iterator` accesses `osc_def.p`). -- **Map iterators** (`map_iterator`, `ordered_map_iterator`): have `.key` (returns `K`) and `.value` (returns `V`). No auto-dereference — use `.value.field` to access value fields. - -**Logical/bitwise (function-call syntax only):** `or(a,b)`, `xor(a,b)`, `and(a,b)`, `not(a)`, `mod(a,b)` — these are **not** infix operators, only callable as functions. Operate on integer types (`u8`/`s8`/`u16`/`s16`/`u32`/`s32`/`u64`/`s64`). - -### Operator Precedence (highest to lowest) - -| Precedence | Operators | Associativity | -|-----------|-------------------------------|---------------| -| 1 | Unary `-` | Right | -| 2 | `.` (field access) | Left | -| 3 | `[expr]`, `?[expr]`, `[a:b]` | Left (postfix)| -| 4 | `(args)` (function call) | Left (postfix)| -| 5 | `*`, `/` | Left | -| 6 | `+`, `-` | Left | -| 7 | `<`, `>`, `<=`, `>=`, `<=>` | Left | -| 8 | `==`, `!=` | Left | - -Note: `or`, `and`, `xor`, `not`, `mod` are functions, not operators — they do not appear in the precedence table. - -### Built-in Functions - -Called as `fn(arg1, arg2, ...)`. - -| Function | Accepts | Returns | -|----------|-------------|-----------| -| `sin` | `f32`/`f64` | same | -| `cos` | `f32`/`f64` | same | -| `pow` | `f32`/`f64` | same | -| `exp` | `f32`/`f64` | same | -| `log` | `f32`/`f64` | same | -| `or` | integer | same | -| `xor` | integer | same | -| `and` | integer | same | -| `not` | integer | same | -| `mod` | integer | same | - -### Lambda Calls - -Any expression that resolves to a lambda can be called: `expr_resolving_to_lambda(arg1, arg2, ...)`. The result type is the return type of the lambda. Bangs are lambdas that take no arguments and return void. - -### Numeric Literals - -- **Integers:** `1`, `42`, `0` — unresolved integer type (`int?`). The concrete type is inferred from context: - - `$0 + 1` where `$0 : u8` → `1` becomes `u8` - - Integer literals also coerce to `f32` or `f64` from context, but only if the value can be represented exactly (f32: |v| <= 2^24 = 16777216, f64: |v| <= 2^53). Values that exceed these limits produce an error. - - If no context resolves the type, it remains `int?` (unresolved). In a complete program all types must be resolved — an unresolved `int?` is a compile error. -- **f32 floats:** `1.0f`, `3.14f` -- **f64 floats:** `1.0`, `3.14` -- **Boolean:** `true`, `false` — `bool` type - -### Built-in Constants - -| Name | Value | Type | -|-------|--------------------------|-------| -| `pi` | 3.14159265358979323846 | `f64` | -| `e` | 2.71828182845904523536 | `f64` | -| `tau` | 6.28318530717958647692 | `f64` | - -These are bare identifiers (no `$` prefix). Their type is unresolved float (`float?`) and coerces to `f32` or `f64` from context (e.g. `pi * $0` where `$0 : f32` → `pi` becomes `f32`). If no context resolves the type, it remains `float?` (unresolved). In a complete program all types must be resolved — an unresolved `float?` is a compile error. Any other bare identifier that is not a built-in function name, constant, or `true`/`false` is an error. - -### Input References (Pin Sigils) - -Inputs to an expression are referenced by sigil + index. The sigil indicates the expected value category: - -| Syntax | Category | Description | -|--------|------------|--------------------------------| -| `$N` | Value | Generic value (any category) | -| `%N` | Data | Data value (plain) | -| `&N` | Reference | Reference to a value | -| `^N` | Iterator | Iterator into a container | -| `@N` | Lambda | Callable function reference | -| `#N` | Enum | Enumeration value | -| `!N` | Bang | Trigger signal | -| `~N` | Event | Event handle (opaque for now) | - -**Naming:** The first occurrence of a pin index can include a name: `$0:my_input`. Subsequent uses must use `$0` directly (no re-naming). - -### Array Manipulation (Broadcasting) - -When an operator or built-in function is applied between a scalar and a collection type (`map`, `ordered_map`, `set`, `ordered_set`, `list`, `queue`, `vector`, `array`, `tensor`), the operation is applied element-wise: - -- The result is a new collection of the same type and size -- For maps, the operation applies to values (keys are preserved) -- The scalar's type must be compatible with the element type - -Example: `sin($0)` where `$0 : vector` → `vector` with sin applied to each element. - -**Exception:** If the function natively accepts the collection type as input, it operates on the collection directly (no broadcasting). Broadcasting only applies when the function signature doesn't match the collection type. - -### Type Inference - -NanoProg uses **bidirectional type inference**: - -1. **Forward inference:** Input types propagate through operators and functions to determine the output type. -2. **Backward inference:** If a downstream consumer expects a specific type, that constraint propagates back to resolve unknown input types. - -**Rules:** -- Unknown input types are assumed valid as long as the rest of the expression type-checks. They are resolved when the connected pin's type becomes known. -- In a complete program, all types must be statically resolved — no unknowns remain. -- **No silent type conversions** except: - - Integer upcasts within the same signedness family (`u8` → `u16` → `u32` → `u64`, `s8` → `s16` → `s32` → `s64`) - - **Iterator-to-reference decay**: a `^iterator` automatically decays to `&T` or `T` when passed to a function. This allows passing iterators directly to functions that operate on element references (e.g. `$it.stop($it)` where `stop` expects `&osc_def` and `$it` is `^list_iterator`). -- **Function call validation**: argument count and types are checked against the function signature. Generic numeric literals (`int?`, `float?`) cannot be used as struct, Named, or container types. -- Connections between incompatible types are errors and render in red. - -### Lambda Construction - -When an `expr` node has a **lambda grab** handle (`as_lambda`): - -1. The node **must** have outputs (or the lambda returns `void`). -2. **Connected inputs are captures** — their values are static at the point of lambda construction (they belong to the caller's graph, not the callee's). Captures are visually indicated in the editor. -3. **Unconnected inputs become lambda parameters**, ordered left to right. -4. **Recursive parameter collection:** If a connected input's own inputs are unconnected, those bubble up as lambda parameters too, recursively, in left-to-right order. The key distinction is whether a value has already been computed in the caller's graph (capture) or needs to be provided by the callee at call time (parameter). - -**Example:** A lambda node has 3 inputs. Input `$0` is connected to a node whose own 2 inputs are unconnected. Input `$1` is connected to a node with 1 unconnected input. Input `$2` is unconnected. The resulting lambda has **4 parameters**: `$0`'s two (left to right), `$1`'s one, then `$2`. - -**Inbound type inference for lambdas:** If a downstream node expects a lambda of type `(u32, u32) -> u32`, the lambda's parameters are typed `u32, u32` and the output must resolve to `u32`. - -## File Format (.nano) - -TOML-like format: - -``` -version = "nanoprog@0" - -[[node]] -guid = "a3f7c1b2e9d04856" -type = "expr" -args = ["$0+$1"] -position = [100, 200] -connections = ["a3f7c1b2e9d04856.out0->b4c8d9e0f1a23456.0"] -``` - -### Connection Format - -Connections use pin IDs: `".->."` - -Pin names: -- Data/lambda inputs: `0`, `1`, `2`, ... or named (e.g. `gen`, `stop`) -- Bang inputs: `bang_in0`, `bang_in1`, ... -- Data outputs: `out0`, `out1`, ... -- Bang outputs: `bang0`, `bang1`, ... -- Lambda grab: `as_lambda` -- Post-bang: `post_bang` diff --git a/docs/patterns.md b/docs/patterns.md new file mode 100644 index 0000000..179039c --- /dev/null +++ b/docs/patterns.md @@ -0,0 +1,593 @@ +# Organic Assembler — Design Patterns + +This document catalogs the recurring design patterns, idioms, and structural motifs +found throughout the Organic Assembler codebase. + +## 1. Sentinel Pattern + +**Problem**: Many graph operations return references to nodes or nets that might not +exist. Checking for null at every call site is error-prone and verbose. + +**Solution**: Pre-allocate sentinel objects (`$empty`, `$unconnected`) that serve as +always-valid stand-ins for missing entities. + +```cpp +// Sentinels created once at graph builder initialization +void ensure_sentinels() { + // $empty — default node (returned when no real node is assigned) + // $unconnected — default net (returned when no real net is assigned) +} + +// Every FlowArg2 always has valid references +struct FlowArg2 { + FlowNodeBuilderPtr node_; // always valid ($empty if unassigned) + NetBuilderPtr net_; // always valid ($unconnected if unassigned) +}; +``` + +**Usage**: Code can unconditionally call `arg->node()->id()` without null checks. +The sentinel returns safe defaults (empty strings, zero positions, etc.). + +**When to use**: Any time an object reference is "optional" but accessed frequently. +Sentinels eliminate the most common source of null pointer bugs. + +**Trade-off**: Requires `is_sentinel()` checks in the few places where the distinction +matters (serialization, rendering). + +--- + +## 2. Observer Pattern (via Interfaces) + +**Problem**: The graph model is shared between the compiler and editor. The editor +needs to react to graph changes (re-render, re-layout), but the model shouldn't +depend on UI code. + +**Solution**: Abstract observer interfaces defined in the core library, implemented +by the editor. + +```cpp +// Core library defines the interface +struct IGraphEditor { + virtual std::shared_ptr node_added( + const FlowNodeBuilderPtr& node) = 0; + virtual void node_removed(const NodeId& id) = 0; + virtual std::shared_ptr net_added( + const NetBuilderPtr& net) = 0; + virtual void net_removed(const NodeId& id) = 0; +}; + +struct INodeEditor { + virtual void on_dirty() = 0; + virtual void on_layout_dirty() = 0; +}; + +struct INetEditor { + // ... +}; +``` + +```cpp +// Editor implements the interface +class Editor2Pane : public IGraphEditor { + std::shared_ptr node_added( + const FlowNodeBuilderPtr& node) override { + // Create visual representation, cache layout + return std::make_shared(node); + } +}; +``` + +**Registration**: Editors register via weak pointers to avoid preventing cleanup: + +```cpp +void GraphBuilder::add_editor(std::weak_ptr editor); +``` + +**When to use**: Whenever a core data structure needs to notify UI or other +subsystems of changes without depending on them. + +--- + +## 3. Mutation Batching + +**Problem**: A single user action (connecting a wire, deleting a node) may require +multiple internal mutations. Firing observer notifications after each micro-mutation +causes flickering, inconsistent state, and redundant re-inference. + +**Solution**: Bracket multi-step operations with `edit_start()` / `edit_commit()`. +All observer callbacks are queued and fired in order only on commit. + +```cpp +void GraphBuilder::edit_start() { + if (!mutations_.empty()) + throw std::logic_error("edit_start: uncommitted mutations"); +} + +void GraphBuilder::add_mutation_call(void* ptr, std::function&& fn) { + mutations_.emplace_back(ptr, std::move(fn)); +} + +void GraphBuilder::edit_commit() { + auto batch = std::move(mutations_); + for (auto& [_, fn] : batch) + fn(); +} +``` + +**Usage**: +```cpp +gb->edit_start(); +gb->add_node(...); // queues notification +gb->add_link(...); // queues notification +gb->edit_commit(); // fires both notifications +``` + +**When to use**: Any time multiple related changes should appear atomic to observers. + +**Invariant**: `edit_start()` throws if there are uncommitted mutations — this catches +cases where a previous edit was abandoned without committing. + +--- + +## 4. Dirty Tracking (Three-Level Cascade) + +**Problem**: The editor needs to know *what* changed to minimize re-rendering and +re-inference work. A global "something changed" flag is too coarse. + +**Solution**: Three levels of dirty flags that cascade upward: + +``` +FlowArg2 (pin/arg) ──dirty──> FlowNodeBuilder (node) ──dirty──> GraphBuilder (graph) +``` + +```cpp +// Arg level: any mutation marks the arg dirty +void FlowArg2::mark_dirty() { + // Mark owning node dirty + node_->mark_dirty(); +} + +// Node level: dirty means "re-render this node" +void FlowNodeBuilder::mark_dirty() { + dirty_ = true; + // Notify node editor + if (auto ed = editor_.lock()) + ed->on_dirty(); +} + +// Layout-only dirty: position changed but semantics didn't +void FlowNodeBuilder::mark_layout_dirty() { + layout_dirty_ = true; + // Does NOT cascade to graph (no re-inference needed) + if (auto ed = editor_.lock()) + ed->on_layout_dirty(); +} +``` + +**When to use**: Any system with hierarchical state where changes at one level +affect ancestors. + +**Key insight**: Layout changes (dragging a node) are tracked separately from +semantic changes (modifying an expression). This prevents node movement from +triggering expensive type re-inference. + +--- + +## 5. Discriminated Union (Kind Enum + as_* Methods) + +**Problem**: A set of related types share a common base but have different fields +and behaviors. `std::variant` works for simple cases but doesn't support +`shared_from_this()` or deep inheritance. + +**Solution**: A base class with a `kind()` enum and `as_*()` downcasting methods. + +```cpp +enum class ArgKind : uint8_t { Net, Number, String, Expr }; + +struct FlowArg2 : std::enable_shared_from_this { + ArgKind kind() const { return kind_; } + bool is(ArgKind k) const { return kind_ == k; } + + std::shared_ptr as_net(); + std::shared_ptr as_number(); + std::shared_ptr as_string(); + std::shared_ptr as_expr(); + +protected: + FlowArg2(ArgKind kind, ...); +private: + ArgKind kind_; +}; + +// Concrete types inherit from the base +struct ArgNet2 : FlowArg2 { /* net-specific fields */ }; +struct ArgNumber2 : FlowArg2 { /* number-specific fields */ }; +``` + +**Compared to std::variant**: +- Supports `shared_from_this()` (variants can't) +- Supports inheritance-based polymorphism +- More explicit control over memory layout +- Trade-off: manual dispatch instead of `std::visit` + +**When to use**: When the types need shared ownership, self-references, or when +more than 4-5 alternative types make `std::variant` unwieldy. + +--- + +## 6. Variant-Based Results + +**Problem**: Functions that parse or construct objects can fail. Exceptions are too +heavy for expected failures. Error codes lose type information. + +**Solution**: Return a `std::variant` of success type and error type. + +```cpp +using BuilderResult = std::variant< + std::pair, + BuilderError +>; + +using ParseAttoResult = std::variant< + std::shared_ptr, + BuilderError +>; + +using ParseResult = std::variant< + std::shared_ptr, + std::string // error message +>; +``` + +**Usage**: +```cpp +auto result = parse_atto(stream); +if (auto* err = std::get_if(&result)) { + report_error(*err); + return; +} +auto& gb = std::get>(result); +``` + +**When to use**: Any function that can fail for expected reasons (parsing, validation, +I/O). Reserve exceptions for invariant violations (programmer errors). + +--- + +## 7. Factory Method with Friend Access + +**Problem**: Objects should only be created through a central manager (GraphBuilder) +to ensure proper registration, initialization, and tracking. + +**Solution**: Private constructors with `friend` access for the factory. + +```cpp +struct ArgNet2 : FlowArg2 { + friend struct GraphBuilder; // only GraphBuilder can construct + + // Public API + const std::string& value() const; + void set_value(const std::string& v); + +private: + ArgNet2(const std::shared_ptr& owner); +}; + +// Factory method on GraphBuilder +std::shared_ptr GraphBuilder::build_arg_net(...) { + auto arg = std::shared_ptr(new ArgNet2(shared_from_this())); + // register in pin tracking, set up sentinels, etc. + return arg; +} +``` + +**When to use**: When object creation involves side effects (registration, tracking) +that must happen consistently. + +--- + +## 8. TypePool Interning + +**Problem**: Type expressions are compared by value throughout the codebase (inference, +codegen, editor display). Creating identical TypeExpr objects wastes memory and makes +equality checks expensive. + +**Solution**: A TypePool that parses type strings once and caches the result. + +```cpp +struct TypePool { + // Pre-cached common types + TypePtr t_void, t_bool, t_string; + TypePtr t_u8, t_u16, t_u32, t_u64; + TypePtr t_s8, t_s16, t_s32, t_s64; + TypePtr t_f32, t_f64; + + // Cache for all parsed types + std::map cache; + + TypePtr intern(const std::string& type_str) { + auto it = cache.find(type_str); + if (it != cache.end()) return it->second; + + TypeParser parser(type_str); + auto type = parser.parse(); + if (type) cache[type_str] = type; + return type; + } +}; +``` + +**Benefits**: +- Type equality reduces to pointer comparison (`t1 == t2`) +- No redundant parsing of the same type string +- Common types (f32, u32, bool) are always available without lookup + +**When to use**: Any system with many small, frequently-compared objects +(types, symbols, identifiers). + +--- + +## 9. Multi-Pass Fixed-Point Inference + +**Problem**: In a dataflow graph, types flow in both directions. Node A's output +type depends on node B's input, but node B's input type depends on node A's output. +A single pass can't resolve all dependencies. + +**Solution**: Iterate the inference passes until no types change (fixed point). + +```cpp +void GraphInference::run() { + clear_all(); + resolve_pin_type_names(); + + bool changed = true; + while (changed) { + changed = false; + changed |= propagate_connections(); + changed |= infer_expr_nodes(); + changed |= propagate_pin_ref_types(); + } + + resolve_lambdas(); + fixup_expr_derefs(); + insert_deref_nodes(); +} +``` + +**Properties**: +- **Monotonic**: Types only become more specific, never less. This guarantees convergence. +- **Order-independent**: The fixed-point result is the same regardless of node ordering. +- **Efficient**: Most graphs converge in 2-3 iterations. Linear chains converge in 1. + +**When to use**: Any constraint propagation system where dependencies are cyclic. + +--- + +## 10. Shadow Node Pattern + +**Problem**: Inline expressions on nodes (e.g., `store! $value` where `$value` is an +expression) need to participate in type inference and codegen, but they aren't +separate nodes in the user-visible graph. + +**Solution**: Auto-generate hidden "shadow" expression nodes at load time. + +```cpp +// User writes: store! $my_value +// System generates: +// 1. A shadow expr node with the inline expression +// 2. A link from the shadow node's output to the store! input +// 3. The shadow node is invisible in the editor +``` + +**Lifecycle**: +- Created at load time (`parse_args()`) +- Participate in inference and codegen +- Removed before serialization +- Invisible in the editor (not rendered) + +**When to use**: When user-facing syntax is more compact than the internal +representation, and the translation is mechanical. + +--- + +## 11. Two-Layer Model (Model + Builder) + +**Problem**: The serialization format needs a simple, fast data structure. The editor +needs a rich, observable, transactional data structure. These are conflicting +requirements. + +**Solution**: Two layers with different trade-offs. + +``` +FlowGraph (model layer) GraphBuilder (builder layer) +├── Simple structs ├── shared_ptr ownership +├── Vectors and strings ├── Dirty tracking +├── Fast to serialize ├── Observer interfaces +├── No smart pointers ├── Mutation batching +├── No callbacks ├── Sentinel objects +└── Used by compiler └── Used by editor +``` + +The builder wraps the model and adds editor-specific capabilities. The compiler +works directly with the model layer, avoiding builder overhead. + +**When to use**: When the same data is consumed by systems with very different +performance and functionality requirements. + +--- + +## 12. Recursive Descent Parsing + +**Problem**: Type strings, expressions, and .atto files all need parsing. Each has +different grammar rules but similar parsing needs. + +**Solution**: Hand-written recursive descent parsers with a consistent structure. + +```cpp +struct TypeParser { + std::string src; + size_t pos = 0; + std::string error; + + bool eof() const { return pos >= src.size(); } + char peek() const { return eof() ? 0 : src[pos]; } + char advance() { return eof() ? 0 : src[pos++]; } + void skip_ws(); + std::string read_ident(); + + TypePtr parse(); // entry point + TypePtr parse_function(); // (args) -> ret + TypePtr parse_struct(); // {fields} + TypePtr parse_container(); // name + TypePtr parse_scalar(); // u8, f32, etc. +}; +``` + +All parsers share this pattern: +- String source + position cursor +- `eof()`, `peek()`, `advance()`, `skip_ws()` primitives +- Error string for diagnostics +- Recursive methods for grammar rules + +**Why not a parser generator?** The grammars are small enough that hand-written +parsers are clearer, faster, and easier to debug. Parser generators add a build +step and obscure the grammar. + +--- + +## 13. Static Descriptor Tables + +**Problem**: Node types have fixed properties (port names, port types, categories) +that are the same for every instance. Storing this per-node wastes memory. + +**Solution**: Static arrays of node type descriptors, indexed by NodeTypeID. + +```cpp +static const NodeType2 NODE_TYPES_V2[] = { + { NodeTypeID::Expr, "expr", NodeKind2::Flow, + { /* input ports */ }, { /* output ports */ }, + /* flags */ }, + { NodeTypeID::New, "new", NodeKind2::Flow, + { /* input ports */ }, { /* output ports */ }, + /* flags */ }, + // ... 38 total +}; +``` + +Each node instance stores only its `NodeTypeID`. All type-specific information +comes from the descriptor table. + +**When to use**: When many instances share the same schema and the schema is +known at compile time. + +--- + +## 14. Pin ID as Structured String + +**Problem**: Pins need globally unique identifiers for serialization, linking, and +inspector subscriptions. Integer IDs would be compact but opaque. + +**Solution**: Structured string IDs with embedded meaning. + +``` +"934e3b98bb914e95.out0" — node GUID + output pin name +"$auto-df6e4aa3d0d8d2bc-out0" — auto-generated pin ID +"$a-3F" — compact re-ID after import +"$empty" — sentinel node +"$unconnected" — sentinel net +``` + +Benefits: +- Human-readable (useful for debugging) +- Self-documenting (you can tell which node owns a pin) +- Stable across edits (GUID-based, not index-based) +- Prefixed sentinels ($) are easy to identify + +Trade-off: Larger than integer IDs, slightly slower to compare. In practice, +the type pool interning pattern mitigates the comparison cost. + +--- + +## 15. Category Sigil Dispatch + +**Problem**: Type categories (Data, Reference, Iterator, Lambda, etc.) need to be +encoded in type strings and dispatched on in rendering, inference, and codegen. + +**Solution**: Single-character sigils with parse/render helpers. + +```cpp +// Parsing +inline TypeCategory parse_category(char c) { + switch (c) { + case '%': return TypeCategory::Data; + case '&': return TypeCategory::Reference; + case '^': return TypeCategory::Iterator; + case '@': return TypeCategory::Lambda; + case '#': return TypeCategory::Enum; + case '!': return TypeCategory::Bang; + case '~': return TypeCategory::Event; + default: return TypeCategory::Data; + } +} + +// Rendering (pin shapes) +switch (category) { +case TypeCategory::Data: draw_circle(pos, radius); break; +case TypeCategory::Bang: draw_square(pos, size); break; +case TypeCategory::Lambda: draw_triangle(pos, size); break; +// ... +} +``` + +The sigils serve triple duty: +1. **Serialization**: Compact type representation in .atto files +2. **Dispatch**: Switch on category for type-specific behavior +3. **Visual**: Pin shapes in the editor correspond to categories + +--- + +## 16.

Not applications, not programs, not sketches -- instruments. That word choice is deliberate and load-bearing. A musical instrument is played, not executed. A scientific instrument measures, not computes. An instrument has a purpose -- it does one thing well. An instrument is expressive -- the same instrument in different hands produces different results. + +Every instrument in the Organic Assembler is a self-contained `.atto` file that defines some interactive, real-time behavior -- typically audio synthesis, visual display, or both. The system compiles these programs, runs them with hot-reload support, and provides a visual node-graph editor for authoring them. The project's repository is called "orgasm" -- short for Organic Assembler. Memorable, irreverent, honest about the creative pleasure of building instruments. + +The "Organic" in the name reflects how instruments grow. You don't write an instrument top-to-bottom like a text program. You grow it organically: place a node, connect a wire, hear the result, add another node, adjust a parameter, watch types propagate through the graph in real time. The "Assembler" reflects what the system does: it assembles your graph of nodes into a running, real-time program. + +## The Core Idea: Visual Dataflow for Real-Time Systems + +The fundamental insight behind the Organic Assembler is that instruments are inherently about signal flow. Audio signals, control signals, event triggers, and UI state all flow between processing nodes. A textual programming language forces you to name intermediate values and linearize a fundamentally parallel, graph-shaped computation. A visual dataflow graph shows topology directly -- you see what connects to what. Wires are the variables. Related nodes are placed near each other. Unconnected subgraphs run independently. You change a connection, you see (and hear) the result immediately. + +But pure visual programming has a weakness: complex mathematical expressions are awkward as node graphs. Nobody wants to wire up `a + b * sin(c)` as six separate nodes. So the Organic Assembler supports inline expressions within nodes. You can type `$0 + $1 * sin($2)` directly inside an expression node, where `$0`, `$1`, `$2` refer to the node's input pins. The graph handles topology and signal routing; inline expressions handle the math. It's a hybrid that takes the best of both worlds. + +## The Language: attolang + +The language is called attolang. "Atto" means 10 to the minus 18 -- smaller than "nano" (10 to the minus 9) by nine orders of magnitude. The project was originally called "nanolang," but as the system grew more complex, its name became more humble. The best names have a sense of humor about themselves. + +attolang has a rich type system with two orthogonal dimensions. The first dimension is TypeKind -- what a value IS. Scalars like u8 through s64, f32 and f64. Booleans, strings. Containers like vector, map, list, set, queue. Fixed-size arrays and tensors. Functions and structs. Symbols and meta-types for compile-time abstractions. + +The second dimension is TypeCategory -- HOW a value is accessed. This is where it gets interesting. There are seven categories, each with its own single-character sigil: + +- Percent sign for Data -- plain values, the default +- Ampersand for Reference -- mutable locations, borrowed from C++ syntax +- Caret for Iterator -- a position into a container, pointing "up" to the current element +- At-sign for Lambda -- callable function references, a function "at" an address +- Hash for Enum -- enumerated, numbered items +- Exclamation mark for Bang -- trigger signals carrying no data, an imperative command: "do this!" +- Tilde for Event -- something that comes and goes, like a wave + +These two dimensions are orthogonal. An ampersand-vector-of-f32 is a mutable reference to a vector of floats. An at-sign-f32-arrow-f32 is a callable that takes and returns a float. An exclamation mark is a bang trigger. This grid of kinds and categories is the DNA of every value in the system. + +## The Bang Chain: Making Dataflow Imperative + +One of the most distinctive features of attolang is the bang chain. In a pure dataflow language, everything happens simultaneously -- data flows through the graph, and every node computes when its inputs are ready. But real-time instruments need side effects: storing values to variables, appending to collections, mixing audio output. Side effects need ordering. You need to say "do this, THEN do that." + +Bang nodes -- nodes postfixed with an exclamation mark, like `store!`, `append!`, `iterate!`, `lock!` -- have explicit execution ordering via bang signals. A bang signal flows from one node's "next" output to another node's "trigger" input, creating a chain. This chain is a sequential program embedded in a parallel graph. + +The naming is perfect. An exclamation mark IS a bang. And the pin names tell you exactly what they do: BangTrigger triggers the node's execution; BangNext fires next, continuing the chain. These are verbs, not nouns -- they describe action, not identity. + +## Bidirectional Type Inference + +attolang's type inference engine is bidirectional, which is unusual and powerful. In most languages, types flow in one direction: the producer determines the type, and the consumer must accept it. But in a visual dataflow graph, producers and consumers are peers. There's no clear "this comes first" ordering. + +Consider a literal `0` in an expression. It could be u8, u16, u32, u64, f32, or f64. The correct type comes from the CONSUMER -- whatever that zero flows into determines what type it should be. Without backpropagation from consumer to producer, every literal would need an explicit type annotation. + +The inference engine runs multiple passes in a fixed-point loop: forward-propagate types through wires, infer expression nodes, backpropagate from consumers -- and repeat until nothing changes. Types only become more specific, never less, which guarantees convergence. Most graphs converge in two or three iterations. + +This is what makes the editing experience feel alive. As you connect nodes, types resolve in real time. You watch pin types update live in the editor. The type system is your development partner, catching errors at edit time rather than at runtime. + +## Literal Types and Symbols: Compile-Time Power + +attolang makes compile-time values first-class citizens of the type system. `literal` represents a compile-time constant with type domain T and value V. The number `42` isn't just "an integer" -- it's `literal,42>`, where the question mark means "the exact unsigned type will be resolved from context." This means the type system knows which values are compile-time constants, enabling optimizations and metaprogramming that would otherwise require a separate constant-folding pass. + +Symbols work similarly. When you type `sin` in an expression, the result isn't immediately "the sine function." It's `symbolf32>` -- a first-class named reference that carries both its name and what it resolves to. An identifier that isn't in the symbol table becomes `undefined_symbol` -- it doesn't error immediately, it errors only when something tries to evaluate it. This means partially-written instruments don't explode with cascading errors. You can have unfinished nodes and the system stays calm. + +## The Four Subsystems + +The Organic Assembler has four major subsystems, each independently buildable with well-defined boundaries. + +**attolang** is the core language library. It defines the data model, type system, expression parser, inference engine, serialization, and graph builder. It has zero external dependencies -- just the C++20 standard library. This is a deliberate constraint: the core is pure computation, no I/O, no GUI, no platform dependencies. + +**attoc** is the compiler. It transforms `.atto` files into self-contained C++ projects. The pipeline loads the file, runs type inference, validates, then generates C++ code: struct definitions from `decl_type` nodes, a program class with event handlers, and a complete CMakeLists.txt. Each compiled instrument is an independent project. + +The decision to compile to C++ rather than interpret or compile to LLVM IR was pragmatic. Audio processing at 48kHz with low latency demands native speed -- an interpreter would add unacceptable overhead. C++ gives access to every audio and graphics library without FFI bridges. Standard debuggers work on the output. And the generated code is human-readable, which aids debugging. When something goes wrong at runtime, you read the generated C++ to understand what happened. + +**attoflow** is the visual node editor, built on SDL3 and Dear ImGui. It has a three-layer architecture: VisualEditor handles canvas rendering (pan, zoom, hover detection, drawing primitives), Editor2Pane wraps the GraphBuilder and implements graph editing semantics (wire connections, node manipulation), and FlowEditorWindow manages the application chrome (tabs, file browser, build toolbar, child processes). This layering means each layer could be reused independently. + +**attohost** is the instrument runtime. It runs instruments in a separate process from the editor, so a crashing instrument doesn't take down your editing session. It supports hot-reload: the compiler generates a DLL, the host loads it, and when you edit and recompile, the host unloads the old DLL and loads the new one. Communication between editor and host happens via named pipes for live value inspection. + +## The Graph as Truth + +A fundamental principle: the FlowGraph is the canonical representation. There is no separate abstract syntax tree, no hidden intermediate form, no shadow copy. What you see in the editor is what gets compiled. What you read in the `.atto` file is what the editor displays. + +This single-source-of-truth principle eliminates an entire class of synchronization bugs. In many development environments, the visual representation can drift from the actual program. In the Organic Assembler, that's structurally impossible. The graph IS the program. + +## The .atto File Format + +Instruments are stored in a TOML-like format. Each file starts with a version marker (`instrument@atto:0`), followed by node definitions and link definitions. Node IDs are hex GUIDs prefixed with `$auto-`. Pin IDs embed their parent node's ID plus a pin name. Named nets use a dollar-sign prefix. + +The version history tells a story of evolution: `nanoprog@0` to `nanoprog@1` to `attoprog@0` to `attoprog@1` to `instrument@atto:0`. Each step has a migration function in the serializer. The system can still load the very first format ever created -- it just saves in the latest format. Old names live on in the migration code, translating the past into the present. + +## Anatomy of an Instrument + +Every instrument has structural elements that map to linguistic categories. + +Declarations are the nouns: `decl_type` defines a struct type, `decl_var` declares a mutable variable that persists across frames, `decl_event` declares an event, `decl_import` imports a standard library module, `ffi` declares an external C function. + +Expressions are the adjectives and adverbs: `expr` computes values from inputs, `new` constructs structs, `dup` duplicates values to branch wires, `cast` converts types, `select` chooses between values based on conditions. + +Bang nodes are the verbs: `store!` writes values, `append!` adds to collections, `iterate!` loops, `lock!` acquires mutexes, `call!` invokes functions with side effects, `output_mix!` writes audio output. + +Events are the stimuli: `on_key_down!`, `on_key_up!`, custom events. An instrument does nothing until an event fires. The audio callback fires 48,000 times per second. Key events fire on user input. + +## The Audio Callback: 48,000 Times Per Second + +Audio runs at 48kHz. Each invocation of the audio callback produces one sample per channel. The pattern is: read state from variables declared outside the callback, compute pure math (oscillators, filters, envelopes), write updated state via `store!`, and output via `output_mix!`. + +The bang chain within the audio callback is the inner loop of the instrument. Every node in this chain runs 48,000 times per second. This is where the real-time constraint bites hardest: no allocations, no string operations, no collection mutations in the hot path. Less than 21 microseconds per sample. Human ears detect latency above about 10 milliseconds as a distinct echo -- this is a physical requirement, not a soft goal. + +The klavier instrument -- a piano synthesizer and the project's most comprehensive test case -- uses oscillator synthesis with per-key state, envelope generators, and additive audio mixing. It exercises complex types, nested lambdas, collections, events, audio, GUI, and FFI. If klavier loads, infers, compiles, and runs, the system is healthy. + +## Design Patterns That Bear Load + +The codebase uses specific design patterns that evolved from real problems. + +The Sentinel pattern pre-allocates always-valid stand-in objects (`$empty` for nodes, `$unconnected` for nets) so that code can unconditionally access references without null checks. Every pin always has a valid node and net reference. This eliminates the most common source of null pointer bugs. + +The Observer pattern connects the model to the editor without creating reverse dependencies. The core library defines interfaces (IGraphEditor, INodeEditor, INetEditor). The editor implements them. The model never imports editor code. When the graph changes, observers are notified. + +Mutation Batching brackets multi-step operations with `edit_start()` and `edit_commit()`. All observer notifications are queued and fired only on commit, so observers always see consistent state. Without this, connecting a wire would fire partial notifications as each micro-step completes. + +Dirty Tracking cascades through three levels: arg to node to graph. A pin mutation marks its owning node dirty, which marks the graph dirty. Layout changes (dragging a node) are tracked separately from semantic changes (editing an expression), so moving a node doesn't trigger expensive type re-inference. + +The TypePool interns all parsed types so that type equality reduces to pointer comparison. No redundant parsing of the same type string. Common types like f32 and bool are always available without lookup. + +## The Naming Philosophy + +Names in the Organic Assembler are not labels slapped on after the fact. They are decisions -- small acts of design that accumulate into the character of the system. The project has a detailed philosophy about naming that permeates every level. + +When connections between nodes changed from point-to-point to broadcast, "wire" was renamed to "net" -- because a net (from electronics) is a set of electrically connected points regardless of physical routing. The old word would have been a lie. + +When pin directions caused confusion (does "BangInput" mean the input that carries a bang, or the bang that inputs to this node?), they were renamed to BangTrigger and BangNext -- verbs that describe what the pins DO, not what they ARE. + +Error messages follow the same philosophy: lowercase, descriptive, context-included. "type mismatch: expected f32, got u8" names the problem in a way that suggests the fix. File names are architecture: putting a file in `src/atto/` is a promise it will never depend on SDL3. Sigils are the shortest possible names, working because the set is small, the context is constrained, and the mnemonics are strong. + +## Differential Everything + +The project has a deep relationship with the concept of differentiation -- rates of change, deltas, accumulation -- at every level. + +At the audio level, an oscillator works by accumulating a phase delta each sample. The phase step is the derivative of the waveform position. The `store!` node performs numerical integration. Frequency IS the derivative of phase. + +At the inference level, the fixed-point loop iterates until the delta between iterations is empty. Types move monotonically from generic to specific. The inference engine is structurally identical to forward-plus-reverse-mode automatic differentiation, with types playing the role of values and gradients. + +At the editing level, dirty tracking computes the delta between "state before edit" and "state after edit" as a deduplicated set of changed items. The wire cache rebuilds only when the underlying model has a non-zero delta. + +At the version level, each format migration encodes the difference between two versions. Loading a `nanoprog@0` file applies a chain of composed deltas. + +Even the git commit history reflects differential development. "towards lambdas," "more graphbuilder work," "not perfect, but progress is progress" -- these are differential checkpoints capturing known-better intermediate states. The question marks in commit messages like "progress in literals?" reveal uncertainty about whether a delta is positive. + +## The Development Story + +The project was built in an intense five-day sprint. Day one (March 23, 2026): 16 commits establishing the foundation -- FlowGraph model, expression parser, type system, code generator, visual editor, first instruments. Day two: 28 commits deepening the type system with literal types, symbol types, shadow nodes, and lambda support. Day three: 36 commits at peak velocity, building out the type system, GraphBuilder, and Editor2. Day four: 72 commits -- the highest output day -- completing Editor2 features. Day five: 6 larger integration commits connecting everything. + +The commit messages tell a story. Feature introductions name the concept: "Observer Pattern," "multi select." Rename commits use arrow notation: "wire -> net in graph_builder." Incremental progress is honest: "towards X," "more X work," "not perfect, but progress is progress." The emotional honesty is a feature, not a bug. + +## The Web Vision + +The future includes web deployment. The editor, built on SDL3 and ImGui, can be compiled to Emscripten for browser execution. A compile server on a hardened Raspberry Pi would accept `.atto` files, compile them through attoc to C++, then through Emscripten to WebAssembly, and send the result back to the browser. + +The server would be containerized with no network access inside, a 60-second timeout, 512MB RAM limit, and read-only root filesystem. Only `.atto` goes in (small attack surface), controlled C++ comes out. This is the "process boundaries are trust boundaries" principle in action. + +## Why It Matters + +The Organic Assembler sits at an intersection that few projects occupy: a system that is both deeply technical (bidirectional type inference, compile-time metaprogramming, multi-pass fixed-point algorithms) and fundamentally creative (building instruments, making sound, exploring expression). + +The type system catches errors at edit time so you can focus on the music, not the debugging. The visual editor shows you the topology of your signal flow so you can reason spatially. The real-time compilation means you hear changes as you make them. The bang chain gives you precise control over execution order without abandoning the parallel nature of dataflow. + +Every feature, every refactor, every design decision is evaluated against one question: does this help someone build a better instrument? If the answer is no, the work is not justified. The system exists to serve instruments, not itself. + +The best instruction is the one you no longer need to give, because the system makes the right choice obvious. That is what the type system, the patterns, and the architecture are for: making the right choice the easy choice. + +--- + +*The Organic Assembler is MIT-licensed and available at github.com/nilware-io/orgasm.* diff --git a/docs/style.md b/docs/style.md new file mode 100644 index 0000000..1697731 --- /dev/null +++ b/docs/style.md @@ -0,0 +1,471 @@ +# Organic Assembler — Style Guide + +This document covers the visual, structural, and API design style of the Organic Assembler +project.

Understanding *why* things are built +this way is essential for making coherent future decisions. + +## The Core Metaphor: Operating System for Instruments + +Organic Assembler is not just a language or an editor. It is an **Operating System for +Instruments**. This framing drives every major architectural decision: + +- **Instruments** (not "programs") are the unit of authorship. Each `.atto` file is a + self-contained instrument — potentially audio, visual, interactive, or all three. +- **The OS** is the ecosystem: compiler, editor, runtime, standard library. It manages + the instrument lifecycle from creation through editing, compilation, execution, and + hot-reload. +- **attolang** is the language, but the language is subservient to the OS concept. The + language exists to make instruments expressible, not as an end in itself. + +This is why the project includes an editor, a runtime with audio/video callbacks, and +FFI bindings for GUI and audio. A language-only project would stop at the compiler. + +## Why a Visual Dataflow Language? + +Instruments are inherently about **signal flow**. Audio signals, control signals, event +triggers, and UI state all flow between processing nodes. A textual language forces the +programmer to name intermediate values and linearize a fundamentally parallel, graph-shaped +computation. + +A visual dataflow graph: +1. **Shows topology directly** — you see what connects to what +2. **Eliminates naming burden** — wires *are* the variables +3. **Supports spatial reasoning** — related nodes are placed near each other +4. **Makes parallelism obvious** — unconnected subgraphs run independently +5. **Enables live editing** — change a connection, see the result immediately + +The trade-off is that text is better for complex expressions. That's why attolang supports +inline expressions within nodes (`$0 + $1 * sin($2)`). The graph handles topology, the +expressions handle math. + +## Why Compile to C++? + +The decision to compile `.atto` → C++ → native binary (rather than interpret or compile +to a custom IR) was driven by pragmatism: + +1. **Performance**: Audio processing at 48kHz with low latency requires native speed. + An interpreter would add unacceptable overhead for real-time audio. +2. **Ecosystem**: C++ gives access to every audio/graphics library. No FFI bridge needed + for SDL, ImGui, or custom DSP code. +3. **Debugging**: Standard C++ debuggers (MSVC, GDB, LLDB) work on the output. No custom + debug tooling needed initially. +4. **Simplicity**: The codegen is a straightforward tree walk. No register allocation, no + instruction selection, no optimization passes. C++ handles all of that. + +The cost is compilation latency (seconds instead of milliseconds). The hot-reload +architecture (DLL swap) mitigates this for the edit-test cycle. + +### Why Not LLVM? + +LLVM would give faster compilation and avoid the C++ intermediate step. But: +- LLVM is a massive dependency (~100MB+ binary) +- LLVM's API changes frequently between versions +- The generated C++ is human-readable, which aids debugging +- LLVM doesn't help with web deployment (Emscripten compiles C++) + +If compilation latency becomes a bottleneck, a WASM codegen backend is the planned +escape hatch — but that's future work. + +### Why Not Interpret? + +An interpreter was considered (and would be the fastest path to "runs in browser"). +The blocker is audio: at 48kHz sample rate, the audio callback runs every ~21 +microseconds per sample. An interpreter would need to be extremely fast, and any +garbage collection pause would cause audio glitches. + +For non-audio instruments (pure GUI tools, data processing), interpretation might +be viable in the future. + +## The Type System Philosophy + +### Why Bidirectional Inference? + +Unidirectional inference (forward-only, Hindley-Milner-style) doesn't work well for +dataflow graphs because: + +1. **Producers and consumers are peers** — in a graph, there's no clear "this comes first" + ordering. A node's output type might depend on its input types (forward), but its input + types might also depend on what its outputs connect to (backward). + +2. **Literal types need context** — `0` could be u8, u16, u32, u64, f32, or f64. The + correct type comes from the *consumer*. Without backpropagation, every literal would + need explicit type annotation. + +3. **Generic containers need both directions** — `vector` resolves when either a + producer provides `vector` (forward) or a consumer expects `f32` elements (backward). + +The multi-pass fixed-point approach (iterate until no types change) handles mutual +dependencies gracefully. + +### Why literal Instead of Constant Folding? + +Traditional compilers fold constants at the IR level. attolang makes literals a *type-level* +concept for several reasons: + +1. **Type resolution**: `42` in `$0 + 42` needs to resolve to the same type as `$0`. If `42` + is just an integer, the type system can't help. As `literal,42>`, the type + system resolves `unsigned` from context. + +2. **Compile-time metaprogramming**: Literal types flow through the graph as type information. + A `decl_type` node receives field names as `literal` inputs. This makes the + type system the compile-time evaluation mechanism. + +3. **No separate constant-folding pass**: The type system handles what would otherwise require + a separate optimization pass. Less code, fewer passes, more unified semantics. + +### Why Symbols? + +Bare identifiers (`sin`, `my_var`, `f32`) produce symbol types rather than immediately +resolving to values. This two-phase approach (parse → symbol, then symbol → value on +consumption) enables: + +1. **Deferred resolution**: `decl_var` receives a *name* as input, not a value. The name is + an `undefined_symbol` until the declaration is processed. This lets the declaration + system work without special-casing the expression parser. + +2. **First-class type references**: `f32` as a symbol decays to `type`. This means type + names and value names live in the same expression language. No separate "type expression" + syntax needed (though struct types `{...}` and function types `(...)→...` do have special + syntax because they contain embedded type references). + +3. **Graceful error handling**: An `undefined_symbol` doesn't error at parse time. It + errors only when something tries to *evaluate* it. This means partial programs (still + being edited) don't explode with cascading errors. + +## The Graph Builder Philosophy + +### Why Two Layers (Model + Builder)? + +The original `FlowGraph` (model layer) is a simple, serializable data structure. It was +designed for file I/O and compiler consumption. But the editor needs: + +- Dirty tracking (what changed since last render?) +- Observer notifications (tell the UI when something mutates) +- Structured access (not just raw string arrays) +- Transactional edits (batch multiple changes atomically) +- Sentinels (never-null references for safe UI code) + +Rather than adding all this to the model (making it complex and slow for the compiler), +a second layer (GraphBuilder) was created. The builder wraps the model and adds +editor-specific concerns. + +This separation means: +- The compiler never pays for editor overhead +- The model remains simple and fast to serialize +- The builder can evolve independently (new UI features don't affect codegen) +- Tests can use either layer (model for fast unit tests, builder for integration tests) + +### Why Sentinels Over Nulls? + +Every `FlowArg2` always has a valid `node()` and `net()`. If no real node/net is assigned, +sentinels (`$empty`, `$unconnected`) are used instead. + +This eliminates an entire class of bugs: null pointer dereferences in UI code. When +rendering a pin, you can always call `arg->node()->id()` without checking for null. +The sentinel returns safe default values. + +The trade-off is a small memory cost (two extra entries in the graph) and the need to +check `is_sentinel()` when the distinction matters. In practice, sentinel checks are +rare — most code just uses the values. + +### Why Mutation Batching? + +Graph edits often involve multiple changes that should appear atomic: +- Moving a node updates its position (one change) and may adjust connected wires (more changes) +- Connecting a wire creates a link and updates both endpoint pins +- Deleting a node removes the node, all its links, and all its pins + +Without batching, each individual change would trigger observer notifications, causing +the UI to re-render partially updated state. This leads to visual glitches and, worse, +can trigger cascading re-inference on incomplete graphs. + +`edit_start()` / `edit_commit()` brackets these multi-step operations. All observer +notifications are queued and fired only on commit, ensuring observers always see +consistent state. + +## The Editor Philosophy + +### Why SDL3 + ImGui? + +SDL3 provides: +- Cross-platform windowing (Windows, macOS, Linux) +- Audio output with low-latency callbacks +- Input handling (keyboard, mouse, gamepad) +- Emscripten support for web deployment + +ImGui provides: +- Immediate-mode UI rendering (no retained widget tree) +- Custom drawing primitives (lines, beziers, filled shapes) +- Text rendering with custom fonts +- Docking and multi-viewport support + +Together they give a lightweight, fast, cross-platform rendering stack that can +run at 60 FPS while drawing complex node graphs. The immediate-mode approach means +the editor re-renders every frame from scratch — no stale cached widgets. + +The alternative (Qt, GTK, etc.) would provide more built-in widgets but add a +massive dependency, slower build times, and less control over the rendering pipeline. +For a node graph editor where everything is custom-drawn anyway, ImGui is ideal. + +### Why Three Editor Layers? + +``` +FlowEditorWindow → Editor2Pane → VisualEditor +(app chrome) (semantics) (rendering) +``` + +1. **VisualEditor** knows about canvas coordinates, zoom, hover detection, and drawing + primitives. It doesn't know about graph semantics. + +2. **Editor2Pane** knows about the GraphBuilder, node types, pin connections, and + wire logic. It doesn't know about window management or file I/O. + +3. **FlowEditorWindow** handles tabs, file browser, build toolbar, and child processes. + It delegates all graph work to Editor2Pane instances. + +This layering means: +- VisualEditor could be reused for a different graph system +- Editor2Pane could be embedded in a different window framework +- The window can manage multiple editors (tabs) without code duplication + +### Why Distance-Based Hover Priority? + +The hover system evaluates all elements (pins, wires, nodes) and returns the best +match by distance, with pins getting a priority bias. + +This is better than z-order-based hit testing because: +1. Pins are small and hard to click — the bias helps +2. Wires can overlap nodes — distance sorting resolves ambiguity naturally +3. No need to maintain a z-order for every element +4. Works correctly at any zoom level (distances scale with zoom) + +## The Wire Philosophy + +### Why First-Class Wires? + +In the original model, connections were arrays on nodes (`inputs`, `outputs`). Wires +had no identity — they were implicit relationships between pins. + +Making wires first-class entities (with their own GUID, metadata, and editor properties) +enables: + +1. **Wire selection**: Click a wire to inspect its type, rename it, add probes +2. **Stable inspector subscriptions**: A wire's GUID persists across recompiles, so + the value inspector can track a specific wire across edit-compile-run cycles +3. **Wire metadata**: Color coding, logging toggles, probe flags, user-assigned names +4. **Decoupled ownership**: Wires don't belong to either endpoint — they're independent + graph entities + +### Why Named Nets? + +Named nets (`$osc-signal`, `$freq`) are a higher-level abstraction over wires. A named +net connects all pins that share the same net name, without requiring explicit wire routing. + +This is useful for: +1. **Long-distance connections**: Connecting nodes far apart without visual wire spaghetti +2. **Bus-like patterns**: Multiple consumers reading the same signal +3. **Modularity**: Reference a signal by name instead of by wire topology + +Named nets are displayed in the nets editor panel, providing a table-of-contents view +of all named signals in the instrument. + +## The Runtime Philosophy + +### Why Process Isolation? + +The editor and runtime run in separate processes (attoflow.exe and attohost.exe) for +one critical reason: **a crashing instrument must not crash the editor**. + +Audio programming inevitably involves buffer overruns, division by zero, and infinite +loops. In a single-process model, any of these would kill the editor, losing unsaved work. +In the two-process model, the host crashes, the editor reports the error, and the user +can fix their instrument and try again. + +### Why wire Instead of Raw Values? + +In release builds, `wire` is a zero-cost typedef to `T`. In inspect builds, it wraps +the value with metadata (name, GUID) and notifies an IPC channel on assignment. + +This dual-mode design means: +- **Release performance**: No overhead. The generated code runs as fast as hand-written C++. +- **Debug observability**: Every signal can be monitored, recorded, and overridden from + the editor without modifying the instrument code. + +The alternative (always wrapping, or separate debug/release codegen paths) would either +add permanent overhead or require maintaining two code generators. + +## Trade-Offs and Known Limitations + +### args String vs Structured Fields + +`node.args` is still a string that gets tokenized at runtime in ~40+ call sites. This is +the single largest source of technical debt. The fix (structured pre-parsed fields) is +planned but is a large refactor touching all node type handling. + +The original design used strings for simplicity: quick to serialize, easy to display, +simple to parse. But as the type system grew more sophisticated, the string became a +liability — it encodes semantic information (type names, variable names, field lists) +in an untyped format that requires error-prone tokenization. + +### Nested Lambda Scope Leakage + +When a `lock` node's lambda body shares nodes with an outer stored lambda, the +parameter collector incorrectly identifies outer parameters as belonging to the +inner lambda. This is because `collect_lambda_params` doesn't respect lambda +boundaries. + +The proper fix requires a pre-inference "lambda ownership" pass that assigns each +node to its innermost enclosing lambda. This is non-trivial because nodes can be +shared between scopes (the graph is not a tree). + +### Single-Threaded Inference + +The inference engine runs single-threaded on the main thread. For large instruments +(100+ nodes), this can cause a noticeable pause. Moving inference to a background +thread would require making the graph immutable during inference (copy-on-write) +or using fine-grained locking. + +### No Undo/Redo + +The editor currently has no undo/redo system. The mutation batching infrastructure +(`edit_start`/`edit_commit`) provides the foundation for command-pattern undo, but +the actual command recording is not yet implemented. + +### Web Compilation Latency + +The planned web deployment relies on a remote compile server, introducing network +latency in the edit-run cycle. For audio instruments, this latency may be +unacceptable. The long-term fix is either a WASM codegen backend in attoc +(eliminating the server) or an in-browser interpreter for rapid prototyping with +a compile step for production. + +## Guiding Principles + +1. **Instruments first**: Every feature is evaluated by whether it helps people + build better instruments. + +2. **Real-time or nothing**: Audio processing at 48kHz with <10ms latency is a + hard constraint. Any design that can't meet this is rejected. + +3. **Graph as truth**: The FlowGraph is the canonical representation. There is no + separate AST, no hidden state. What you see in the editor is what gets compiled. + +4. **Types prevent errors**: The more information encoded in the type system, the + more errors are caught at edit time rather than at runtime. + +5. **Zero-cost abstractions**: Features like `wire` that add development-time + capabilities without production-time overhead. + +6. **Simple until proven insufficient**: Start with strings, switch to structured + types when the strings become a problem. Start with single-threaded, add + parallelism when profiling demands it. + +7. **Process boundaries are trust boundaries**: The editor doesn't trust the + runtime. The compile server doesn't trust user input. Each boundary has + explicit validation. diff --git a/scenes/klavier/main.atto b/scenes/klavier/main.atto new file mode 100644 index 0000000..105b641 --- /dev/null +++ b/scenes/klavier/main.atto @@
