A high-performance command-line interface for browsing RAI Televideo, the Italian teletext service, written in Rust. A fun side project with a pinch of nostalgia.

• High-quality image rendering with automatic terminal protocol detection (iTerm2, Kitty, Sixel, or Unicode half-blocks).
• Full-screen TUI with fixed header and footer bars.
• Fast navigation with arrow keys and direct page jumping.
• 5-minute caching for faster page loads.
• Navy blue status bars with white text, classic teletext style.

• Rust 1.70 or higher
• A terminal that supports 24-bit true color
• Recommended terminals:
  • iTerm2 (macOS)
  • Terminal.app (macOS)
  • Windows Terminal (Windows)
  • Kitty, Alacritty, or similar (Linux)

cargo build --release

The binary will be at target/release/televideo.

cargo install --path .

Run the application:

./target/release/televideo

Or if installed globally:

televideo

• ← / → - Previous/Next page
• ↑ / ↓ - Previous/Next sub-page
• 0-9 - Type a page number (100-899)
• Enter - Go to the typed page number
• Backspace - Delete last digit of page number
• Escape - Clear page number input
• c - Clear image cache
• q or Ctrl+C - Quit the application

The application:

1. Fetches PNG images from RAI's Televideo servers
2. Automatically detects terminal capabilities and uses the best available rendering method:
   • iTerm2 inline images protocol (best quality)
   • Kitty graphics protocol
   • Sixel protocol
   • Unicode half-blocks (▄) as fallback
3. Uses ratatui for precise TUI layout control (header always at top, footer at bottom)
4. Implements a 5-minute cache to reduce server requests
