| [`PositionMapper`](../docs/api/position-mapper) | Maps positions between original and expanded code |

## Quick Example

TypeScript

```
import { expandSync } from "@macroforge/core";

const sourceCode = \`
/** @derive(Debug) */
class User {
  name: string;
  constructor(name: string) {
    this.name = name;
  }
}
\`;

const result = expandSync(sourceCode, "user.ts", {
  keepDecorators: false
});

console.log(result.code);
// Output: class with toString() method generated

if (result.diagnostics.length > 0) {
  console.error("Errors:", result.diagnostics);
}
```
