A sleek terminal syntax highlighting file viewer — like cat, but prettier.

catr displays file contents in your terminal with full syntax highlighting, line numbers, file metadata, and a clean formatted layout powered by Pygments.

Features

• Syntax highlighting for hundreds of languages (Python, C, JavaScript, YAML, and more)
• Line numbers with aligned gutter

• Works as a global CLI command after installation
