[Sugar-devel] [PATCH sugar 02/21] style cleanup: move globals before class and method definitions

Sascha Silbe sascha-pgp at silbe.org
Sat Oct 16 18:20:04 EDT 2010


This only touches the globals that were flagged by pep8 due to white space
issues.

I've also left the sunflower layout variables alone. AFAICT this layout is
currently unused and should be removed instead (or factored out like the snow
flake layout and reenabled).
