/** * Computes the effective TypeScript rootDir for an emit, mirroring how the * TypeScript compiler determines it when `rootDir` is not set in tsconfig. * * When `rootDir` is explicitly configured, its absolute, normalized form is * returned. Otherwise the longest common parent directory of the input file * list is used (the same heuristic TypeScript applies through * `Program#getCommonSourceDirectory`). * * Returns `undefined` if no rootDir can be determined (e.g. no input files). * * @param explicitRootDir Value of `compilerOptions.rootDir` from tsconfig, if any. * @param fileNames List of TypeScript input files (absolute paths). * @param cwd Current working directory used to resolve relative paths. */ export declare function getEffectiveRootDir(explicitRootDir: string | undefined, fileNames: readonly string[] | undefined, cwd?: string): string | undefined;
