<div>
<pre>With std::experimental::string_view comes a new UDL, operator""sv -
clang-format however inserts an extra space when trying to use it, breaking
compile. Operator""s for std::string is processed correctly.
Before formatting:
cat test.cc
#include <string>
#include <experimental/string_view>
using namespace std::experimental;
using namespace std::string_literals;
const auto x = "broken"sv;
const auto y = "works"s;
After:
clang-format -style=Google test.cc
#include <experimental/string_view>
#include <string>
using namespace std::experimental;
using namespace std::string_literals;
const auto x = "broken" sv;
const auto y = "works"s;</pre>
</div>
