Using clang-format and clang-tidy hooks with pre-commit to lint your C/C++ code.
Note
Automatically downloads a specific version of clang-format or clang-tidy binaries and installs it on the system.
Add this to your .pre-commit-config.yaml
repos: - repo: https://github.com/cpp-linter/cpp-linter-hooks rev: v0.3.0 # Use the ref you want to point at hooks: - id: clang-format args: [--style=Google] # Other coding style: LLVM, GNU, Chromium, Microsoft, Mozilla, WebKit. - id: clang-tidy args: [--checks='boost-*,bugprone-*,performance-*,readability-*,portability-*,modernize-*,clang-analyzer-*,cppcoreguidelines-*']The example of using custom config: .clang-format and .clang-tidy
repos: - repo: https://github.com/cpp-linter/cpp-linter-hooks rev: v0.3.0 hooks: - id: clang-format args: [--style=file] # to load .clang-format - id: clang-tidy args: [--checks=.clang-tidy] # path/to/.clang-tidyThe example of using any version of clang-tools.

Then it will just print instead of changing the format. E.g:
