I actually wrote that patch! Are you sure you are using a version of clang with support for it? As far as I know a new release hasn't been cut with the included patch. At Facebook we use clang-format with that patch and it works. I should note that Alcatraz's clang plugin looks to have a compiled version of an old clang-format in the tree...that's likely why this doesn't work with that plugin.
