# ClangFormat - Developer Instructions¶

This file primarily outlines the procedure of formatting the entire MRPT codebase with ClangFormat in case this is needed again, or in case we upgrade to a more recent version of ClangFormat.

## Notes on formatting the codebase¶

At present (Dec-2019) we use clang-format-8.

ClangFormat doesn’t go well with // comments or code doxygen blocks. If there are cases where the linter returns with an error, correct the occurrences manually. Usually a manual reflow of the comments is needed. For code blocks you can also keep them as is with // clang-format [on|off] directives.

It is advised to set the AlignTrailingComments config var to false, as it keeps reindenting comments between successive ClangFormat runs.
