An interactive git diff TUI viewer

About

• A Rust-based TUI tool that provides a Side-By-Side comparison view for intuitively reviewing git changes
• Supports per-file navigation, vertical and horizontal scrolling, syntax highlighting, and color marking of added/deleted lines
• Supports both keyboard and mouse navigation, with Vim-style shortcuts
• Includes search within the diff (type / then navigate with n/N) and a per-file review status toggle (r)
• Compares differences between local and remote branches with an upstream-ahead strategy
  • Supports ranges with --base / --head for explicit comparison
  • The --include-uncommitted option can include uncommitted changes and untracked files
• Review status is stored locally in .git/deff/reviewed/ so it persists
• Language-aware syntax highlighting and line-level color emphasis make changed sections highly readable
• Dark theme by default; dark/light/auto theme can be set with the --theme option
