* [clang-tidy] remove redundant string initialization Found with readability-redundant-string-init Signed-off-by: Rosen Penev <rosenp@gmail.com> * [clang-tidy] switch to raw strings Easier to read. Found with modernize-raw-string-literal Signed-off-by: Rosen Penev <rosenp@gmail.com> * [clang-tidy] fix performance issues Found with performance* Signed-off-by: Rosen Penev <rosenp@gmail.com> * fix extra comma warnings Found with clang's -Wextra-semi-stmt Signed-off-by: Rosen Penev <rosenp@gmail.com> * remove JSONCPP_OP_EXPLICIT This codebase in C++11. No need for compatibility with C++98. Signed-off-by: Rosen Penev <rosenp@gmail.com> * remove JSONCPP_NOEXCEPT This codebase is C++11 now. No need for this macro.
