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.

To install cpplint from PyPI, run:

$ pip install cpplint

If you get the "This environment is externally managed" error, try to search and install cpplint with your system's package manager (e.g. apt, rpm, pacman...). If it doesn't exist, you can either package cpplint for your distribution or repeat the steps above with the --break-system-packages flag.

$ cpplint [OPTIONS] files

For full usage instructions, run:

$ cpplint --help

Thanks to Google Inc. for open-sourcing their in-house tool.
