oyo

oyo [options] [file]

oyo is a step-through diff viewer that extends traditional diffs with an evolution mode. You can use it like a normal diff viewer with scrolling and hunk navigation, or step through changes one at a time watching the code evolve from old to new.
View modes include unified, split, evolution, and blame. It supports clipboard integration and can be configured as a git difftool.

~/.config/oyo/config.toml

Configuration file for UI settings including view mode, auto-centering, line wrapping, and scrollbar display.

Best used with Git integration. Standalone diff viewing requires properly formatted diff input.

oyo was created by ahkohd and is written in Rust.
