oyo is a terminal diff viewer that combines a classic scrollable diff with a
step-through way to review changes.

This tool has different diff modes, such as a dual mode for scrolling through
diffs or stepping incrementally, a unified mode where code transforms in one
pane, a split  mode for side-by-side old and new versions, has an evolution
mode with deletions fading out and a blame mode for Git annotations per line.

Other features of oyo include handling hunk navigation to jump between change
groups, multi-file support, regex search across diffs, a command palette for
quick actions, syntax highlighting, word-level diff marking, animated steps,
line wrapping, Git integration as a difftool, autoplay at set speeds and
helpful keyboard bindings.
