The algorithm resides in the two added modules, btm_matcher and btm_utils. New code has been added to drive the new matching process in refactor.py and a few minor changes were made in other modules. A BM_compatible flag(False by default) has been added in fixer_base and it is set to True in most of the current fixers. ........ r84216 | benjamin.peterson | 2010-08-19 16:44:05 -0500 (Thu, 19 Aug 2010) | 1 line allow star_expr in testlist_gexp ........ r84274 | benjamin.peterson | 2010-08-22 18:40:46 -0500 (Sun, 22 Aug 2010) | 1 line wrap long line ........ r84275 | benjamin.peterson | 2010-08-22 18:42:22 -0500 (Sun, 22 Aug 2010) | 1 line cleanup ........ r84276 | benjamin.peterson | 2010-08-22 18:51:01 -0500 (Sun, 22 Aug 2010) | 1 line when there's a None value and a traceback, don't call type with it #9661 ........ r84375 | george.boutsioukis | 2010-08-31 08:38:53 -0500 (Tue, 31 Aug 2010) | 3 lines Idiomatic code changes & stylistic issues fixed in the BottomMatcher module.
