+### clang-format
+
+[homepage](https://clang.llvm.org/docs/ClangFormat.html). [changelog](https://releases.llvm.org/download.html). `clang-format` is a formatter for c, c++, c#, objective-c, protobuf, javascript, and java. You can use clang-format in any language-specific format, but usually you will be creating a generic format.
