Diff Viewers — Version Control Tools

This project is a command-line text viewer designed to enhance terminal output through automatic syntax highlighting and integrated file management. It functions as a replacement for standard system pagers, providing a readable interface for large text streams, source code, and markup files by applying color-coded formatting directly to the terminal output. The utility distinguishes itself through deep integration with version control systems, allowing users to inspect repository status and historical file changes with visual markers displayed in the output margin. It employs heuristic-based language detection and syntax-tree parsing to ensure accurate formatting, while also providing a diagnostic mode that reveals hidden control characters and non-printable symbols to assist with data integrity and troubleshooting. Beyond its primary viewing capabilities, the tool integrates into existing shell workflows to provide syntax-aware previews for search results, manual pages, and fuzzy finder navigation. It automatically manages terminal dimensions and pipe status to delegate long-form content to external system pagers or concatenate data for further command-line processing.
