Return export nodes of ast when resolving alias symbol

Search Terms

export star node

Suggestion

Add an API which returns alias symbol of import specifier and the export nodes on the searching path.

Use Cases

I want to write a little tool to extract certain type in typescript code and its dependent types.
Current approaches just return the alias symbol, and it's difficult to establish relationship between import specifier and export star statements.

Examples

a.ts:

import {C} from './b';

b.ts:

export * from './c';
export * from './d';
export * from './e';

c.ts:

export const C = 1;

I want to get not only the location of symbol "C", but also the export star node in the AST of "b.ts", which is "export * from './c'".

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

ファイル、テスト、またはコンパイラのエントリポイントは指定されていません。まず、例の import に対して alias シンボルと export-star 宣言がどのように解決されるかを追跡します。完了の条件は、emitted JavaScript を変更せずに、検索パス上の alias シンボルと export ノードの両方を public API が返すことです。
