-d Dry run. Analyze, but don't make any changes to, files.
-r Recurse. Search for all .py files in subdirectories too.
-v Verbose. Print informative msgs.
Search Python (.py) files for future statements, and remove the features
from such statements that are already mandatory in the version of Python
you're using.
Pass one or more file and/or directory paths. When a directory path, all
.py files within the directory will be examined, and, if the -r option is
given, likewise recursively for subdirectories.
Overwrites files in place, renaming the originals with a .bak extension. If
cleanfuture finds nothing to change, the file is left alone. If cleanfuture
does change a file, the changed file is a fixed-point (i.e., running
cleanfuture on the resulting .py file won't change it again, at least not
until you try it again with a later Python release).
Limitations: You can do these things, but this tool won't help you then:
+ A future statement cannot be mixed with any other statement on the same
physical line (separated by semicolon).
+ A future statement cannot contain an "as" clause.
Example: Assuming you're using Python 2.2, if a file containing
from __future__ import nested_scopes, generators
is analyzed by cleanfuture, the line is rewritten to
from __future__ import generators
because nested_scopes is no longer optional in 2.2 but generators is.
