+**ForEachMacros** (``std::vector<std::string>``)
+ A list of macros that should be interpreted as foreach loops instead of as
+ function calls.
+
+ For example, ``ForEachMacros: [BOOST_FOREACH, Q_FOREACH]`` tells
+ clang-format to treat ``BOOST_FOREACH`` and ``Q_FOREACH`` as loop control
+ statements.
+
**IndentCaseLabels** (``bool``)
Indent case labels one level from the switch statement.
