How do I set up pre-commit hooks for formatting and linting for C++ projects?

Setting up pre-commit hooks for formatting and linting in C++ projects is an essential practice to ensure code quality and consistency. By utilizing tools such as ClangFormat for formatting and Clang-Tidy for linting, you can automate the code-checking process before committing changes to your repository.

Here’s how you can set up pre-commit hooks in your C++ project:

#!/bin/sh # Pre-commit hook for linting and formatting C++ files # Check for C++ files that are staged for commit files="$(git diff --cached --name-only --diff-filter=ACM | grep '\.cpp\|\.h')" # Exit if no C++ files are staged if [ -z "$files" ]; then exit 0 fi # Linting step with Clang-Tidy for file in $files; do clang-tidy "$file" -- -std=c++17 done # Formatting step with ClangFormat for file in $files; do clang-format -i "$file" git add "$file" # Re-add the formatted files to staging done
