Prints output to stdout. Output files can optionally be written to a different directory and or have an extra file suffix appended to their name for use in situations where you do not want to replace the input files. r c ss | | _ | | _ | r8 | j t j � r8 | t j 7} | | _ | | _ | | _ t t | � j | | | � d S)aF Args: fixers: A list of fixers to import. options: A dict with RefactoringTool configuration. explicit: A list of fixers to run even if they are explicit. nobackups: If true no backup '.bak' files will be created for those files that are being refactored. show_diffs: Should diffs of the refactoring be printed to stdout? input_base_dir: The base directory for all input files. This class will strip this path prefix off of filenames before substituting it with output_dir. Only meaningful if output_dir is supplied. All files processed by refactor() must start with this path. output_dir: If supplied, all converted files will be written into this directory tree instead of input_base_dir. append_suffix: If supplied, all files output by this tool will have this appended to their filename. Useful for changing .py to .py3 for example by passing append_suffix='3'.
