Overview

This document describes how to use the clang-format tool for code style checking, including checking methods for scenarios with and without a default configuration file.

Checking Process

Different checking commands are executed depending on whether the .clang-format configuration file exists in the project.

Note: The openvela project uses clang-format 14 version for code style checking.

Scenario 1: Checking with Default Configuration File

When a default code style configuration file .clang-format exists in the project:

clang-format -n <filepath> --Werror

Parameter Description

• -n: Check only, do not modify files.
• --Werror: Treat formatting warnings as errors.

Scenario 2: Checking with WebKit Style

When a default code style configuration file does not exist in the project:

clang-format --style=WebKit -n <filepath> --Werror

Parameter Description

• -n: Check only, do not modify files.
• --Werror: Treat formatting warnings as errors.
• --style=WebKit: Use WebKit predefined code style.
