Overview

Plugin-supplied resolver for custom named / generic type vocabulary in RBS::Extended payloads. ADR-13 § “Decision”.

Subclasses override #resolve to return a Type::Base when the node matches the vocabulary the resolver covers, or ‘nil` to fall through to the next resolver in the chain (and finally to the built-in / RBS fallback). The base implementation returns `nil` so an unimplemented subclass is a safe no-op.

Resolvers are registered through their plugin’s manifest under the ‘type_node_resolvers:` slot:

class RigorTypescriptUtilityTypes < Rigor::Plugin::Base
  manifest(
    id: "typescript-utility-types",
    version: "0.1.0",
    type_node_resolvers: [Resolvers::Pick.new,
                          Resolvers::Omit.new]
  )
end

ADR-13 — base class, manifest hook, and registry aggregation for plugin-contributed type-node resolvers. Resolvers declared via ‘manifest(type_node_resolvers:)` run for every real `%arigor:v1:…` payload through `TypeNode::ResolverChain` (built by `Environment#build_name_scope` from `Plugin::Registry#type_node_resolvers`).

Resolvers SHOULD be stateless and re-entrant; the registry builds the chain once per ‘Analysis::Runner.run` and may consult any resolver multiple times for the same node.

Instance Method Summary

• #resolve(node, scope) ⇒ Rigor::Type::Base^?

  Resolved type, or ‘nil` to fall through.

Instance Method Details

#resolve(node, scope) ⇒ Rigor::Type::Base^?

Returns resolved type, or ‘nil` to fall through.

Parameters:

• node (Rigor::TypeNode::Identifier, Rigor::TypeNode::Generic) —

  the parser-emitted node the chain is asking about.

• scope (Rigor::TypeNode::NameScope) —

  companion value object (slice 3); slice 2 invocations MAY pass ‘nil` because the chain doesn’t exist yet.

Returns:

• (Rigor::Type::Base, nil) —

  resolved type, or ‘nil` to fall through.
