// Based on https://github.com/kevva/executable
// Since this module doesn't expose the function to check stat mode only,
// his logic is pasted here.
// Opened an issue and a pull request about it,
// to maybe switch to module in the future:
// Issue: https://github.com/kevva/executable/issues/9
// PR: https://github.com/kevva/executable/pull/10

export function isExecutable(fileStat) {
  if (process.platform === 'win32') {
    return true;
  }

  return Boolean(
    (fileStat.mode & parseInt('0001', 8)) ||
    (fileStat.mode & parseInt('0010', 8)) ||
    (fileStat.mode & parseInt('0100', 8))
  );
