oyo extends traditional diffs with an optional step-through mode. Use it like a normal diff viewer with scrolling and hunk navigation, or step through changes one at a time and watch the code evolve. You can switch between both modes at any time.
This is free and open source software.
Key Features
- Classic diff mode (no-step) Scroll the full diff with hunk navigation, no stepping required.
- Step-through navigation Move through changes one at a time with keyboard shortcuts.
- Hunk navigation Jump between groups of related changes in both modes.
- Three view modes:
- Single: Watch the code morph from old to new state.
- Split: See old and new versions with synchronized stepping.
- Evolution: Watch the file evolve, deletions simply disappear.
- Word-level diffing: See exactly which words changed within a line.
- Multi-file support: Navigate between changed files with preserved positions.
- Search: Regex search with to jump between matches.
- Syntax highlighting: Toggle on/off for code-aware coloring (auto-enabled in no-step mode).
- Line wrap: Toggle wrapping for long lines.
- Animated transitions: Smooth fade in/out animations as changes are applied.
- Playback: Automatically step through all changes at a configurable speed.
- Git integration: Works as a git external diff tool or standalone.
- Commit picker: Browse recent commits and pick ranges interactively (oy view).
- Themes: Built-in themes plus .tmTheme syntax themes (configurable).
- Configurable: XDG config file support for customization.
