[llvm-dev] Creating my own “clang-format” style that can be used across multiple projects with the “BasedOnStyle” setting

[Timothy Wrona via llvm-dev]

Thanks Nathan, I believe that would suit my needs pretty well!

It still feels a bit rigid if it just expects files to be in specific
directories (C++ project structures tend to vary wildly haha). I would
ultimately like to be able to specify a relative path in my CMakeLists file
to tell it where to look for a .clang-format or .clang-tidy file. But
either way I think I can achieve what I need with the proposed enhancement.
:)

Thanks,
Tim
