cpplint
Google C++ style guide checker
TLDR
SYNOPSIS
cpplint [options] files
DESCRIPTION
cpplint is a static code checker for C++ that verifies code against Google's C++ style guide. It checks for style errors, formatting issues, and common programming mistakes to enforce consistent code standards across projects.The tool examines source files for compliance with naming conventions, spacing rules, comment formatting, header guard patterns, and many other style requirements. It helps teams maintain uniform code style and catch common errors before code review.Originally developed by Google for internal use, cpplint is now maintained as an open-source project. While designed specifically for Google's style guide, its rules can be filtered and customized for projects with different conventions.
