The vivacore library, developed by Andrey Karpov and Evgeniy Ryzhkov, is designed for static analysis, testing, and verification of C/C++ code, intended to streamline software development by providing essential functionalities to third-party developers. It supports various tools such as software reengineering, quality assurance, source code documentation, and migration, offering features like tokenization and abstract syntax tree generation. Vivacore is seen as a successor to the openc++ library, focusing on classical code analysis rather than full parsing for compiler development.
