How to call clang-format over a cpp project folder?

Question

Is there a way to call something like clang-format --style=Webkit for an entire cpp project folder, rather than running it separately for each file?

Here is a solution that searches recursively and pipes all files to clang-format as a file list in one command. It also excludes the "build" directory (I use CMake), but you can just omit the "grep" step to remove that.

shopt -s globstar extglob failglob && ls **/*.@(h|hpp|hxx|c|cpp|cxx) | grep -v build | tr '\n' ' ' | xargs clang-format -i
