This function loops through all translator filesystem entries that are captured by the wildcard and the directory specifier. The wildcard is glob-style and supports * and ? modifiers. The scan can be made recursive to enter every directory it finds, so that files and folders of a whole directory tree are captured. This function is used to process filesystem objects inside of directories without having to add the filenames into a configuration file. This greatly increases flexibility when processing files. Other than scanDirEx, this function returns a table of directories and files.


table translator.scanDir ( string dirPath, string wildcard, bool recursive )


  • dirPath: a path to the directory the scan shall take place or start in
  • wildcard: glob-style wild-card for filename matching; every filename that matches the wild-card is returned
  • recursive: a boolean that specifies whether the whole directory tree at dirPath should be included into the scan


This function returns a table consisting of all directories and all matching file entries which were found during the scan. It returns false if dirPath is an invalid path specifier for the translator.
