cpplint is a fast, cross-platform C++ style checker for Node.js compatible runtimes, designed to help developers maintain consistent coding standards in their C++ projects. Built using cpplint-cpp, a C++ re-implementation of the original Python-based cpplint, it offers prebuilt binaries for Linux, macOS, and Windows, with no runtime dependency on Python or clang. This tool is ideal for C++ developers working in Node.js environments who want to automate and streamline their code linting process.
