dead-ringer-1.2.1 is not a library.
dead-ringer
A Rust-based command-line utility designed to compare two binary files, displaying differences by showcasing both hexadecimal and ASCII representations of the differing bytes.

Features
- CLI Diff Viewer for Hex and ASCII.
- Color highlighting for different data types to enhance readability.
- Keyboard navigation enables interactive exploration of differences.
- Search for hex byte sequences (
/) or ASCII strings (?), withn/Nto cycle through matches. - Displays byte offset for focused data, aiding in precise location identification.

Clipboard (tmux)
Copy to clipboard uses the OSC 52 escape sequence, which works natively in most modern terminals (iTerm2, kitty, foot, WezTerm, etc.). If you run inside tmux 3.3+, add the following to ~/.tmux.conf so the sequence is forwarded to the outer terminal:
set -g allow-passthrough on
Then reload with tmux source-file ~/.tmux.conf.
Examples
The examples/ directory contains pre-built binary file pairs for testing:
