GLib.path_get_basename

function path_get_basename(file_name: String): String {
    // Gjs wrapper for g_path_get_basename()
}
  

Gets the last component of the filename.

If file_name ends with a directory separator it gets the component before the last slash. If file_name consists only of directory separators (and on Windows, possibly a drive letter), a single separator is returned. If file_name is empty, it gets ".".
