Z S) StdoutRefactoringToola2
A refactoring tool that can avoid overwriting its input files.
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.

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'.
