cpplint - static code checker for C++

Cpplint is a command-line tool to check C/C++ files for style issues according to Google's C++ style guide.

Cpplint used to be developed and maintained by Google Inc. at google/styleguide. Nowadays, Google is no longer maintaining the public version of cpplint, and pretty much everything in their repo's PRs and issues about cpplint have gone unimplemented.

This fork aims to update cpplint to modern specifications, and be (somewhat) more open to adding fixes and features to make cpplint usable in wider contexts.

Installation

Use [pipx](https://pipx.pypa.io) to install cpplint from PyPI, run:

$ pipx install cpplint

Usage

$ cpplint [OPTIONS] files

For full usage instructions, run:

$ cpplint --help

cpplint can also be run as a pre-commit hook by adding to .pre-commit-config.yaml:

- repo: https://github.com/cpplint/cpplint
  rev: 2.0.0
  hooks:
    - id: cpplint
      args:
        - --filter=-whitespace/line_length,-whitespace/parens

Changes

• python 3 compatibility
• more default file extensions
• customizable file extensions with the --extensions argument
• continuous integration on github
• support for recursive file discovery via the --recursive argument
• support for excluding files via --exclude
• JUnit XML output format
• Overriding repository root auto-detection via --repository
• Support #pragma once as an alternative to header include guards
• ... and quite a bit more
