Show HN: AI Pair Programmer for Emacs (github.com)

CodeTutor has been introduced as a new Emacs package designed to function as an interactive AI-based pair programming tutor. It enhances the coding experience by providing a side panel that offers context-aware guidance without directly editing the developer's project files. This package reviews code changes upon saves, explains underlying concepts, suggests the next best steps, and allows for follow-up queries, effectively mimicking the interaction one might have with a senior engineer. Significantly, CodeTutor emphasizes an educational approach to coding, focusing on teaching rather than simply providing code solutions. It gathers project context and utilizes backends like Codex and pi while ensuring safety by processing requests in a read-only mode. The package is designed for seamless integration with Emacs versions 28.1 and newer, and it gracefully adapts to the presence of tree-sitter support. By fostering a learning environment, CodeTutor not only supports developers in immediate tasks but also encourages deeper understanding and architectural memory retention, thus contributing positively to the overall competence of the AI/ML community in practical coding scenarios.
