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.
Features
- Terminal Pagers - A text viewer that manages large output streams by providing automatic scrolling, line numbering, and integration with standard system tools.
- Syntax Highlighters - A terminal tool that applies color-coded formatting to text files and command output to improve readability and visual structure.
- Terminal Rendering Engines - Outputs ANSI color codes and formatting instructions directly to the standard output stream for interpretation by the host terminal emulator.
- Manual Page Enhancers - The terminal utility enhances manual page readability by applying syntax highlighting to documentation files through integration with system pager environment variables.
- Syntax Highlighting Engines - Uses a library to parse source code into tokens and map them to terminal color sequences based on language definitions.
- Git Diffing Engines - Queries the local version control system to calculate line-level status changes and maps them to visual markers in the output margin.
- Version Control History Viewers - The terminal utility facilitates the examination of historical file versions by piping version control content into a viewer that applies syntax highlighting for improved readability.
- Version Control Status Integrations - The terminal utility integrates Git status tracking to display local repository modifications and status markers in the sidebar, providing immediate visual feedback on version control changes.
- Diff Viewers - Visualizing repository changes and historical file states directly in the terminal with clear status markers and colorized diffs.
- Output Pagers - The terminal utility manages large text streams by automatically piping content to a pager for easier reading or concatenating data for further command-line processing.
- Terminal Output Formatters - Improving the readability of command line output by adding syntax highlighting and formatting to plain text streams.
- Version Control Integration Tools - A utility that displays repository status markers and historical file changes directly within the terminal viewing experience.
- Heuristic Language Detectors - Analyzes file extensions and content patterns to select the appropriate syntax definition file before initiating the rendering process.
- Command Line Productivity Tools - Streamlining daily development tasks by integrating advanced file viewing, paging, and search result highlighting into existing shell workflows.
