emitted dts is bundled source

This is only an issue on v5.11.8. src/index.ts:

const message = 'Hello World'

export const main = () => {
  console.log(message)
}

main()

dist/index.d.ts:

const message = 'Hello World!';

const main = () => {
  console.log(message);
};

main();

export { main };

expected dist/index.d.ts (emitted on v5.11.7):

declare const main: () => void;

export { main };

tsup config:

{
    "entry": ["src/index.ts"],
    "format": ["esm"],
    "dts": true
}

[egoist]

should be fixed in v5.11.9

I got something different.

"tsup": "^5.11.9"

tsc’s dts is not the same as what tsup is emitting (noEmit: false or true, bundle: false)

Why tsup emit a config-5727ad8.d.ts file (splitting: true or false)? Why import 'vite', import 'webpack', …?
