 Before you push your code, you can run the following that finds all source code files, and then formats them all in place.
 
 ```
-find . -iname "*.hpp" -o -iname "*.cpp" -o -iname "*.c" -o -iname "*.h" | xargs -I {} clang-format -i -style='{IndentWidth: 4, ReferenceAlignment: Left}' {}
+find . -iname "*.hpp" -o -iname "*.cpp" -o -iname "*.c" -o -iname "*.h" -o -iname "*.tpp" | xargs -I {} clang-format {}
 ```
 
 You can also add this to your editors formatting system or some precommit step.
