A beautiful, high-performance terminal text viewer with syntax highlighting and line numbers. Built with Go and the Atlas Suite philosophy.

atlas.cat is a minimalist alternative to cat or bat, designed to provide high-fidelity syntax highlighting and a smooth TUI paging experience within the terminal.

• Syntax Highlighting: Powered by Chroma for 200+ languages.
• Interactive Paging: Smooth scrolling, searching, and window management via Bubble Tea.
• Dual Mode: Seamlessly switch between interactive TUI and direct stdout output.
• Minimalist: Fast, dependency-light, and keyboard-centric.
