Interactive side-by-side git diff viewer
deff is a Rust TUI for interactive, side-by-side file review of git diffs.
It supports reviewing local branch changes against upstream, explicit commit
ranges, and uncommitted or untracked files in your working tree.
Features include:
- Side-by-side panes with independent horizontal scrolling
- Per-file navigation with keyboard and mouse controls
- Vim-like motions and in-diff search
- Syntax highlighting with added/deleted line tinting
- Per-file reviewed toggles with local persistence under .git
