Overview

Immutable analyzer scope: holds local-variable bindings and a reference to the surrounding Environment. State changes return new scopes through explicit transition methods (#with_local). The central query is #type_of(node), the Rigor counterpart of PHPStan’s $scope->getType($node).

#class_ivars_for(class_name) ⇒ Object

Slice 7 phase 2 — class-level ivar accumulator. Keyed by the qualified class name (e.g. ‘“Rigor::Scope”`); the value is a `Hash[Symbol, Type::t]` of every ivar that appears as a write target inside any def body of that class. `StatementEvaluator#build_method_entry_scope` seeds the method body’s ‘ivars` map from this table so a `def get; @x; end` reads the type written in a sibling `def init; @x = 1; end`.

‘ScopeIndexer` populates the table once at index time through a separate pre-pass over the program. The map is frozen and shared by structural reference across every derived scope.

#data_member_layout(class_name) ⇒ Object

ADR-48 — per-class table mapping a fully qualified class name to its ordered ‘Data.define` / `Struct.new` member-name list. Populated by `ScopeIndexer` for both the constant-assigned form (`Point = Data.define(:x, :y)`) and the named-subclass form (`class Point < Data.define(:x, :y)`). Consumed by Inference::MethodDispatcher::DataFolding so `Point.new(…)` on a `Singleton` receiver materialises a precise member instance. Returns nil when the class has no recorded layout.

#declared_types ⇒ Object

ADR-53 Track A — the seed-time discovery tables live on the DiscoveryIndex the scope carries by a single reference; the per-table readers stay on Scope so engine call sites and plugins are unaffected by the extraction. The whole index is swapped in one transition through #with_discovery.

‘declared_types` carries the identity-comparing `Prism::Node => Rigor::Type` declaration overrides `ExpressionTyper#type_of(node)` MUST consult before any other dispatch (a `module Foo` / `class Bar` header types as `Singleton[<qualified path>]` rather than `Dynamic`).

#discovered_method?(class_name, method_name, kind) ⇒ Boolean

Slice 7 phase 12 — in-source method discovery. Maps a qualified class name to a ‘Hash[Symbol, Symbol]` of `method_name => :instance | :singleton`. Populated by `ScopeIndexer` from every `Prism::DefNode` and recognised `define_method` invocation inside class/module bodies. The `rigor check` undefined-method and wrong-arity rules consult this map to suppress diagnostics for methods the user has defined dynamically, even when no RBS sig describes them.

Returns:

  • (Boolean)

#discovered_method_visibility(class_name, method_name) ⇒ Object

v0.1.2 — per-class table mapping ‘method_name (Symbol) →:public | :private | :protected`. Populated by `ScopeIndexer` for every `def` it sees inside a class body, with the visibility taken from the surrounding `private` / `protected` / `public` modifier state plus any post-hoc `private :name, …` named-argument calls. Consumed by the `def.method-visibility-mismatch` rule so explicit-non-self calls to a private method surface a diagnostic.

#evaluate(node, tracer: nil) ⇒ Object

Statement-level evaluation: returns the pair ‘[type, scope’]‘ where `type` is what the node produces and `scope’‘ is the scope observable after the node has run. The receiver scope is never mutated. See Inference::StatementEvaluator for the catalogue of nodes that thread scope; everything else defers to #type_of and returns the receiver scope unchanged.

#includes_of(class_name) ⇒ Object

ADR-24 slice 2 — per-class/module table mapping a fully qualified user class or module to the list of module names it ‘include`s / `prepend`s, AS WRITTEN at the mixin call. Populated by `ScopeIndexer` (per-file plus the cross-file pre-pass) and consumed by `ExpressionTyper#resolve_user_def_through_ancestors` so an implicit-self call resolves against an included module’s ‘def`s, not just the superclass chain. As-written names are resolved to qualified classes at walk time.

end

#indexed_narrowing(receiver_kind, receiver_name, key) ⇒ Object

Closes the “‘params ||= []; params << x`” precision gap (ROADMAP § Type-language / engine — indexed-collection narrowing through `Hash ||= default`). After `receiver ||= default`, the next read at `receiver` is known non-nil; recording the post-`||=` type keyed on `(receiver_kind, receiver_name, literal_key)` lets the ExpressionTyper’s ‘[]` dispatch hand back the narrowed type. Receiver-rebind and `[]=`/mutator invalidation rules are documented at the call sites in `Inference::StatementEvaluator`.

end

#ivar(name) ⇒ Object

Slice 7 phase 1 — instance/class/global variable bindings. ‘ivar(name)` / `cvar(name)` / `global(name)` return the type currently bound for the named variable, or `nil` when the variable has not been written in the analyzed slice of the program. The first cut tracks bindings only within a single method body (each `def` enters with a fresh binding map), so reads in other methods of the same class fall through to `Dynamic`. Cross-method ivar/cvar inference is a follow-up slice.

end

#join(other) ⇒ Object

Joins this scope with another at a control-flow merge point. The joined scope is bound to every local that BOTH branches bind, with the type widened to the union of both sides. Names bound in only one branch are dropped from the joined scope; the eventual statement-level evaluator (Slice 3 phase 2) is responsible for nil-injecting half-bound names where the language semantics demand it. The two scopes MUST share the same Environment.

Raises:

  • (ArgumentError)

#method_chain_narrowing(receiver_kind, receiver_name, method_name) ⇒ Object

Closes the “stable receiver method-chain narrowing” gap (ROADMAP § Future cycles / Type-language / engine —“Method-call receiver narrowing across stable receivers”; 2026-05-28 Redmine survey). After ‘if x.last.is_a?(Array)` the dominated body’s ‘x.last` reads MUST observe the truthy-narrowed type; the same chain reaching the falsey edge observes the negative narrowing.

Address shape mirrors #indexed_narrowing: stable root variable + no-arg single-hop method name. See ChainKey for the precise contract.

#superclass_of(class_name) ⇒ Object

ADR-24 slice 2 — per-class table mapping a fully qualified user-class name to its superclass name AS WRITTEN at the ‘class Foo < Bar` declaration (`“Bar”`, possibly a qualified `“A::B”`). Populated by `ScopeIndexer` — per-file plus the cross-file project pre-pass — and consumed by `ExpressionTyper#try_user_method_inference` to walk the superclass chain when an implicit-self call does not resolve against the enclosing class’s own defs. The as-written name is resolved to a qualified class at walk time against the call’s lexical nesting.

#top_level_def_for(method_name) ⇒ Object

v0.0.3 A — top-level def lookup for implicit-self calls. Returns the ‘Prism::DefNode` for a top-level (or DSL-block-nested, outside any class body) `def <method_name>` in the file, or nil. The sentinel key is owned by `Inference::ScopeIndexer::TOP_LEVEL_DEF_KEY`; consumers should treat its presence as an opaque implementation detail and go through this accessor.

  node
end

#toplevel? ⇒ Boolean

ADR-34 § “Decision” — predicate identifying a toplevel-shaped scope (no enclosing ‘class` / `module` body). True at the top of a file AND inside a top-level `def` body (since toplevel defs leave `self_type` nil per the existing scope-construction contract, mirroring how ADR-24’s ‘adoptable_self_call_result?` also keys on `self_type.nil?` for the same context). Used by `CheckRules#unresolved_toplevel_diagnostic` to gate the `call.unresolved-toplevel` rule so it fires only outside class / module bodies, where Rails-DSL metaprogramming leniency (ADR-24 WD3 → WD4) does not apply.

Returns:

  • (Boolean)

#user_def_for(class_name, method_name) ⇒ Object

v0.0.2 #5 — per-class table mapping ‘method_name (Symbol) → Prism::DefNode`. Populated by `ScopeIndexer` alongside `discovered_methods` for instance-side defs only (singleton-side and `define_method`-introduced methods do not contribute a static body the engine can re-type). Consumed by `ExpressionTyper` to do inter-procedural return-type inference when the receiver class is user-defined and has no RBS sig.

end

#user_def_site_for(class_name, method_name) ⇒ Object

Companion to #user_def_for: returns the ‘“path:line”` where the project defines `class_name#method_name` (instance-side), or nil. Populated only by the cross-file project pre-pass (Inference::ScopeIndexer.discovered_def_index_for_paths) — a `Prism::Location` hides its source file, so the site is recorded at scan time. `CheckRules#undefined_method_diagnostic` consults this to name the defining file when a project monkey-patch on a core/stdlib/gem class is called cross-file, so the diagnostic can point at `pre_eval:` (ADR-17) instead of reading as a bare unresolved call.

#with_self_type(type) ⇒ Object

Slice A-engine. Returns a scope with ‘self_type` set to `type`, preserving locals and facts. `StatementEvaluator` injects this at class-body and method-body boundaries; `ExpressionTyper` consults it when typing `Prism::SelfNode` and implicit-self `Prism::CallNode` receivers.

#with_source_path(path) ⇒ Object

ADR-11 per-call-site assertion gating prerequisite. The analyzer’s per-file boundary stamps the current source file’s path onto the seed scope; nested rebuilds carry the value through so plugin rules (‘dynamic_return`’s ‘file_methods:` gate, sigil checks) can resolve “which file does this call site belong to?” without thread-locals.
