Flint++ A CPP Linter for better coding

C/C++ Flint++

A few weeks ago I published a little side project called Flint++ to Github. Flint++ is a Cross-Platform, Zero-Dependency rewrite of Facebook’s flint project which they use to sanitize their codebase. The original flint is a great piece of software, but through poor documentation and difficult library and OS dependencies few people have taken to using it during their workflows. The aim of Flint++ is to make getting and running this tool too easy to pass up, and thereby help incite good coding practices and well written software.

The original flint is published on Github; and for discussions, there is a Google group.
