Rich-CLI is a command line toolbox for syntax highlighting and formatted output in the terminal.
The tool solves the problem of viewing and rendering various file types with rich formatting directly from the command line. It wraps the Rich library to provide syntax highlighting for many file formats, with specialized rendering for Markdown, JSON, CSV, and Jupyter notebooks. Users invoke the rich command followed by a file path to display highlighted output, with options to customize appearance through line numbers, indentation guides, themes, and wrapping behavior.
The tool suits developers and system administrators who frequently inspect code and data files in the terminal and want better readability than plain text. It works well for quick file inspection workflows where opening a dedicated editor is unnecessary. The project is built on the Rich library, so adoption makes sense for teams already using Rich for terminal output in their applications. The tool handles format detection automatically based on file extensions but allows explicit lexer specification when needed.
The project maintains active development with regular commits addressing bug fixes and feature additions. The codebase receives ongoing refinement to improve rendering quality and expand format support. Documentation is kept current with examples and usage instructions for different installation methods across platforms.
