// Name: Batch Rename Files
// Description: Renames files in a directory using a template.
// Author: JosXa

// 1. Get the directory from the user.
const directory = await path({
  onlyDirs: true,
  placeholder: 'Pick a directory to rename files in',
});

// 2. Get the template for the new file names.
const templateString = await template(
  'NewName_$1',
  {
    placeholder: 'Enter the file name template (use $1, $2... for sequence)',
  },
);

// 3. Read the files from the directory.
const files = await readdir(directory);

// 4. Construct final paths.
const operations = files.map(async (file, index) => {
  const newName = templateString.replace('$1', String(index + 1)); // TODO: Support $2, $3 etc.

  const oldPath = path.join(directory, file);
  const newPath = path.join(directory, newName + path.extname(file));

  return { oldPath, newPath, file };
});

// 5. Perform renames.
for (const operationProm of operations) {
  const { newPath, oldPath, file } = await operationProm;

    console.log(`Renamed "${file}" to "${path.basename(newPath)}"`);
  } catch (error) {

  }
}

// 6. Notify user.
