[TypeScript] Rename Symbol doesn't work as expected with Declaration Merging #62065
Description
Type: Bug
Does this issue occur when all extensions are disabled?: Yes
When renaming symbols in TypeScript, the feature doesn't take into account declaration merging. As a result, renaming symbols breaks references. Renaming the subsequent symbols to match does not fix the references. Whether the imports are explicit or default seems to have no effect.
Steps to Reproduce:
- Create a class and a namespace with the same name, export them
- Import the merged symbol in another file, use references to both the class and namespace
- Attempt to rename the original class & namespace without breaking the references
// file: MyWonderfulClass.class.ts
export class MyWonderfulClass {
// Absolutely wonderful things
}
export namespace MyWonderfulClass {
export interface MyWonderfulClassType {}
}
export default MyWonderfulClass;// file: script.ts
import MyWonderfulClass from "./MyWonderfulClass.class";
const inst = new MyWonderfulClass();
const obj: MyWonderfulClass.MyWonderfulClassType = {};VS Code version: Code 1.102.0 (cb0c47c0cfaad0757385834bd89d410c78a856c0, 2025-07-09T22:10:34.600Z)
