TypeScript 'export type * from' makes the whole file parse to no symbols #2474
Description
Version: codegraph 1.6.2, macOS arm64 (bundled runtime)
What happens
codegraph init warns:
packages/sdk/src/index.ts: parse produced no symbols (tree has errors) — the file is indexed but contributes nothing to the graph
The file is a barrel:
export { FooClient, FooApiError, type FooClientOptions } from "./client.js";
export { DAYS_OF_WEEK } from "./types.js";
export type * from "./types.js";export type * from "..." is TypeScript 5.0 syntax. The parse error drops the whole file, including the valid re-exports above it, so imports through the barrel don't resolve.
Minimal repro: a fresh repo whose src/index.ts is only export type * from "./types.js"; gives the same warning; removing that line from the barrel above makes it go away.
Expected
export type * from parses, or failing that only that statement is skipped and the other re-exports still produce edges.

Thanks for the clear report and the minimal repro!
The TypeScript grammar CodeGraph bundles has no rule for TypeScript 5.0's
export type * from(upstream's doesn't either), so the line came out as a parse error. #2837 is merged tomainand now reads it as theexport *it is to the graph. A barrel like yours no longer reports "parse produced no symbols" or shows up incodegraph statusas unparsed.The error only ever covered that one line, so the barrel's other re-exports were still read. Names imported through it already link to their declarations on
mainvia #1955 and #2526.It all ships in the next release; re-index after upgrading to clear the stored warning.
