@​typespec/compiler

Deprecations

• #10876 Deprecated deepClone utility in favor of structuredClone. All internal usages have been replaced with the native structuredClone API.

Features

• #10897 ApplyCodeFixExpect.toEqual now accepts Record<string, string> to assert on multiple files after a code fix is applied. This enables testing code fixes that write to a different file (e.g., adding augment decorators to a client.tsp).

  await ruleTester
    .expect({
      "main.tsp": `import "./client.tsp";\nmodel Foo { name: string; }`,
      "client.tsp": ``,
    })
    .applyCodeFix("add-client-override")
    .toEqual({
      "client.tsp": `@@override(Foo.name, "clientName");\n`,
    });

• #10548 Add kind: project and entrypoint support to tspconfig.yaml for defining project boundaries and entrypoint resolution. See Project Configuration for more details.

  kind: project
  entrypoint: src/service.tsp
  emit:
    - "@typespec/openapi3"

• #10694 Added support for accessing late-bound members on models that use template spreads or is bases.

  Previously, accessing a member that was introduced via a template instantiation would fail with an invalid-ref error:

  model Template<T> {
    ...T;
  }
  model User is Template<{name: string}>;
  alias UserName = User.name; // ❌ previously: "Model doesn't have member name"

  Now, the compiler will force-evaluate the container type when a member lookup fails on a model with unknown members (from template spreads or is), making late-bound members accessible:

  model Template<T> {
    ...T;
  }

... (truncated)
