Refactor code into modern languages with AI-powered GitLab Duo

This post details how GitLab Duo, powered by Anthropic Claude 3.5, can be used for code refactoring across different programming languages and standards. It provides examples of generating Java 7 code and refactoring it to Java 8, as well as refactoring C++ code across various standards (C++03 to C++14, C++23 to C++11). The post highlights the use of IDE extensions (VS Code, JetBrains) and specific prompts for code generation, explanation, and refactoring. It also mentions refactoring COBOL, C to Rust, Perl to Python, JavaScript, and Bash to ZSH/SH.
