clang-format
Clang-Format is an LLVM-based code formatting tool
Decision gist · record as of 2026-08-14
Yes, if you need clang-format in a Python environment or CI pipeline. The package is actively maintained, has no runtime dependencies, carries a permissive license, and offers broad platform support. Install friction is moderate due to platform-specific wheels, but that is expected and handled transparently by pip. No known vulnerabilities.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Medium install friction due to platform-specific binary wheels for multiple architectures (x86_64, ARM, ppc64le, s390x, and others across Linux, macOS, Windows).
- Package is actively maintained with a release 34 days ago and no runtime dependencies to manage.

What it is and what it does
clang-format is a Python distribution of the LLVM clang-format utility, which automatically formats C, C++, and CUDA code according to a style guide. Instead of downloading and installing clang-format separately from your system package manager, you can install it directly from PyPI as a Python package, making it easier to pin a specific version and use in CI/CD pipelines or development workflows.
The package provides pre-built binaries for many platforms (Linux on x86_64, ARM, ppc64le, s390x; macOS on Intel and Apple Silicon; Windows on x86 and ARM64). It integrates well with pre-commit hooks and can be run via pipx for one-off invocations without a full installation. The versioning of the package matches the underlying clang-format release, so version 22.1.8 corresponds to LLVM clang-format 22.1.8.
Use it for
- Enforce consistent C/C++ code style in CI/CD pipelines by installing a pinned clang-format version without system dependencies
- Use as a pre-commit hook to automatically format staged C++ files before commit
- Run clang-format on demand via pipx in GitHub Actions or other CI runners without pre-installation steps
- Distribute a development environment where all team members use the same clang-format version regardless of OS
