cpp-linter-hooks

cpp-linter-hooks integrates clang-format and clang-tidy hooks with pre-commit to lint your C/C++ code efficiently.

Note

This hook automatically downloads a specific version of clang-format or clang-tidy binaries and installs it on the system.

Usage

Add the following configuration to your .pre-commit-config.yaml:

repos:
  - repo: https://github.com/cpp-linter/cpp-linter-hooks
    rev: v0.4.0  # 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-*']

To use custom configurations like .clang-format and .clang-tidy:

repos:
  - repo: https://github.com/cpp-linter/cpp-linter-hooks
    rev: v0.4.0
    hooks:
      - id: clang-format
        args: [--style=file]  # to load .clang-format
      - id: clang-tidy
        args: [--checks=.clang-tidy] # path/to/.clang-tidy

To use specific versions of clang-tools:

repos:
  - repo: https://github.com/cpp-linter/cpp-linter-hooks
    rev: v0.4.0
    hooks:
      - id: clang-format
        args: [--style=file, --version=16] # Specifies version
      - id: clang-tidy
        args: [--checks=.clang-tidy, --version=16]  # Specifies version

Output

clang-format output

clang-format.............................................................Failed
- hook id: clang-format

The diff between the modified file is as follows:

 #include <stdio.h>

Use --dry-run in args of clang-format to print instead of changing the format, e.g.:
