c++ - Is there a way to configure clang-format to keep nested namespace declarations on the same line? -

in codebase i'm working in, declare nested namespaces thusly:

namespace foo { namespace detail {  // stuff  } }  // foo::detail namespace 

i haven't yet been able find way configure clang-format not break out multiple lines:

namespace foo { namespace detail {  // stuff  } }  // foo::detail namespace 

i've played around breakbeforebraces configuration, , i've looked new bracewrapping configuration in clang 3.8, both without success.

is possible without annotating code // clang-format [on/off]?

it turns out feature has been considered clang-format team, has been rejected. additional details, see https://llvm.org/bugs/show_bug.cgi?id=17928.
