Show HN: Delta – LLM tool for targeted code edits (github.com)

Delta is a newly introduced minimal LLM-powered code editor designed specifically for targeted code edits, enabling developers to efficiently manage their coding tasks. This innovative tool distinguishes itself from traditional integrated development environments (IDEs) by allowing users to point it at specific files and request changes, focusing solely on creating or editing files—essentially covering 99% of code modification needs. Targeted at experienced developers, Delta simplifies the coding process by ensuring precise control over context, utilizing a fuzzy-search-and-replace algorithm for changes while providing features for validation and review, such as automatic testing and visual diff reports. The significance of Delta lies in its streamlined approach to code editing, addressing common frustrations experienced with existing LLM-powered tools that often struggle with project navigation and context management. Delta's functionality includes automatic backups, session management, and a flexible command-line interface, which enhances collaboration with developers’ preferred environments. By optimizing context selection and minimizing irrelevant file interactions, Delta allows users to code more efficiently and accurately, ultimately saving time and reducing errors. This tool is not only compatible with major LLMs like OpenAI and Anthropic but also supports local models, making it a versatile addition to the AI/ML toolkit for software development.
