Diff Reviewer

Diff Reviewer is a VS Code extension that brings an interactive, hunk-by-hunk review workflow directly into your editor. Browse your uncommitted changes in a sidebar, open any file to see its diff inline, and approve or reject individual change groups - all without leaving VS Code.

Features

• Sidebar file tree - All files with uncommitted changes (staged + unstaged vs HEAD) listed in one place, including untracked new files
• Inline diff view - Full file content with change hunks highlighted at their exact line positions - no side-by-side pane switching
• Per-hunk approve / reject - Review each change group independently; rejecting a hunk reverse-applies it on disk immediately
• Approve or reject an entire file - One-click buttons in the sidebar context menu to bulk-approve or bulk-reject all hunks in a file
• Undo everything - Every approve and reject action is fully undoable
• Stable hunk tracking - Approvals are keyed by content, not line number, so they survive when other hunks shift position after edits
• Syntax highlighting - Server-side highlighting via highlight.js for accurate colorization
• Theme-aware - Seamlessly follows VS Code light and dark themes

Requirements

• Git must be installed and available on your PATH
• VS Code v1.85 or later
• Open a folder that contains a Git repository

Getting Started

1. Open a Git repository in VS Code
2. Click the Diff Reviewer icon in the Activity Bar (left sidebar)
3. The Modified Files panel lists all files with uncommitted changes
4. Click any file to open its inline diff view
5. Use the Approve and Reject buttons on each hunk to approve or reject it

Usage

Reviewing a file

Click a file in the Modified Files panel to open the diff view. Each changed region (hunk) is highlighted inline within the full file context. Use the action buttons on each hunk to:

• Approve - Mark the hunk as reviewed (no disk change)
• Reject - Reverse-apply the hunk on disk, removing those changes from your working tree

Approving or rejecting an entire file

You can Approve (✓) or Reject (✗) an entire file directly from the sidebar. This applies the action to every pending hunk in the file at once.

Undoing an approval

After approving a hunk, hover the mouse on top of the "APPROVED" label, it will turn into an "UNDO" button. WARNING: Rejected hunks can't be undone.
