Fuzzyc, an island grammar-based fuzzy C/C++ parser, was originally introduced in a paper “Chucky: Exposing Missing Checks in Source Code for Vulnerability Discovery” with its source code provided at https://github.com/fabsx00/joern.
Fuzzyc parser is based on an island grammar that allows the parser to analyze code without requiring code to be compiled or a build environment to be configured.
The code was migrated to a new repository (https://github.com/joernio/joern) and integrated with other projects, and this directory pulls only the Fuzzyc ANTLR grammar files from the repo.
Note: the Fuzzy C/C++ Antlr grammar files were removed from the original source as of Jun 27, 2022 (https://github.com/joernio/joern/commit/61ed5b010d77b7705bd0e99144fcbc1acaf4d26c).
