Build Cursor Tab in less than 300 lines of Lua (jda.bearblog.dev)

A new Neovim plugin has been developed to provide efficient code completion, utilizing the Qwen 2.5 Coder 1.5b model in under 300 lines of Lua. This project was initiated out of curiosity regarding Cursor's impressive speed in code suggestions, prompting the builder to create a local model that achieves similar performance. The plugin architecture employs asynchronous HTTP requests to ensure that the user interface remains responsive while fetching code completions, effectively eliminating delays that typically hinder coding workflows. Significant for the AI/ML community, this development highlights the feasibility of integrating local machine learning models into existing code editors, enhancing user experience without requiring substantial resources. Key technical details include the use of Neovim’s jobstart for non-blocking API calls, a debounce timer to limit request frequency, and a virtual text system to display suggestions without disrupting the coding flow. The foundation allows for future enhancements like context awareness, the ability to show multiple completion options, and language-specific tuning, making this a promising step toward more intelligent coding environments.
