Quick Diff Apply

Quick Diff Apply is a VS Code extension that lets you interactively apply unified diffs from the clipboard, hunk by hunk, with a visual preview.

Features

• Interactive Hunk Review: Paste a unified diff and review each hunk individually before applying it to your document.
• Visual Diff Highlighting: Deleted lines are highlighted, and added lines are shown as phantom text in the editor, providing a clear visual guide.
• Flexible Application: Choose to apply or reject each hunk, giving you fine-grained control over the changes.
• Context Menu Integration: Easily initiate a diff application by right-clicking on a file in the explorer.

Usage

1. Copy Diff: Copy a unified diff (e.g., from git diff -u or a GitHub PR) to your clipboard.
2. Open Target File: Open the file in VS Code that the diff should be applied to.
3. Apply Diff Command:
   • Open the Command Palette (Ctrl+Shift+P or Cmd+Shift+P) and type Quick Diff Apply: Apply Diff from Clipboard, then press Enter.
   • Alternatively, right-click the target file in the VS Code Explorer and select "Apply Diff from Clipboard".
4. Review Hunks:
   • Code lenses will appear above each hunk, allowing you to "Apply this Hunk" or "Reject this Hunk".
   • Use the commands "Apply All Remaining Hunks in File" or "Discard All Changes in File" for bulk operations.
   • As hunks are applied or skipped, the view updates to reflect the changes and moves to the next hunk.

Requirements

• VS Code version 1.99.0 or newer.

Extension Settings

This extension does not add any VS Code settings.

Known Issues

• The visual representation of added lines (phantom text) is a simulation. The actual lines are inserted only when a hunk is applied.
