Subject: Formatter: No spaces around '=' in @property lines.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=7084823f8ec4367019940b26245e01684b62c7e1;p=clang

Formatter: No spaces around '=' in @property lines.

Before:
@property(assign, getter = isEditable) BOOL editable;

Now:
@property(assign, getter=isEditable) BOOL editable;

It'd be nice if some Apple person could let me know if spaces are preferred
around '=' in @synthesize lines (see FIXME in the test).
