clang-format is a tool to reformat C/C++ to the right coding style.
The mozlint integration of clang-format can be run using mach:
$ mach lint --linter clang-format <file paths>
To enable clang-format on new directory, add the path to the include section in the :searchfox:`clang-format.yml <tools/lint/clang-format.yml>` file.
While excludes: will work, this linter will read the ignore list from :searchfox:`.clang-format-ignore file <.clang-format-ignore>` at the root directory. This because it is also used by the ./mach clang-format -p command.
clang-format can reformat the code with the option --fix (based on the upstream option -i).
To highlight the results, we are using the --dry-run option (from clang-format 10).
