📖 How It Works

Automatic Capture

Visual Code Time Machine captures snapshots in these scenarios:

• On typing - After 3 seconds of inactivity
• On save - Immediately when you save a file (Ctrl+S)
• On file creation - When you create new files or folders
• On file deletion - When you delete files or folders

Storage Structure

your-workspace/
├── .history_machine/
│   ├── blobs/              # Content storage (deduplicated)
│   │   ├── abc123def...    # File content by hash
│   │   └── 456789ghi...
│   └── manifest.json       # Timeline index
├── src/
├── package.json
└── ... (your files)

Time Travel Process

When you jump to a snapshot:

1. Scan current state - Identifies all current files
2. Load snapshot state - Retrieves files from that point in time
3. Remove future files - Deletes files that didn't exist yet
4. Restore past files - Recreates files that were deleted later
5. Update content - Overwrites all files with their historical versions

🎮 Usage Examples

Example 1: Undo Multiple Changes

You're working on a feature and make several changes across multiple files.
Suddenly you realize you want to go back to before you started.

1. Open Time Machine panel
2. Find the snapshot from before you started (e.g., "30m ago")
3. Click "Jump Here"
4. Your workspace is instantly restored!

Example 2: Recover Deleted Files

You accidentally delete an important file and save the changes.

1. Open Time Machine panel
2. Click "This Week" to filter recent snapshots
3. Find a snapshot from before the deletion
4. Click "Jump Here"
5. The deleted file is automatically restored!

Example 3: Compare Different States

You want to see what files existed at different points in your project.

1. Open Time Machine panel
2. Click "View Files" on any snapshot
3. A new panel opens showing all files at that moment
4. Use the search box to find specific files
5. Compare with current state

Example 4: Export a Snapshot

You want to extract a working version from 2 days ago.

1. Open Time Machine panel
2. Click "Yesterday" or search for the specific time
3. Click "Export" on the desired snapshot
4. Choose a folder location
5. Complete workspace state is exported!

Snapshot Actions

Each snapshot has three actions:

• View Files - Opens a panel showing all files in that snapshot
• Export - Exports the snapshot to a folder
• ⏮️ Jump Here - Restores your workspace to this snapshot

⚙️ Commands

Access these via Command Palette (Ctrl+Shift+P or Cmd+Shift+P):

• Code Time Machine: Revert to Snapshot - Jump to a specific snapshot
• Code Time Machine: Clear History - Delete all snapshots
• Code Time Machine: Export Snapshot - Export a snapshot to a folder
• Code Time Machine: View Snapshot Files - View files in a snapshot

🔧 Configuration

Exclusions

By default, these folders are excluded from snapshots:

• .history_machine/ (the extension's storage)
• node_modules/
• .git/

Storage Location

All snapshots are stored in .history_machine/ in your workspace root.

Important: Add .history_machine/ to your .gitignore if you're using Git:

echo ".history_machine/" >> .gitignore

💡 Tips & Best Practices

✅ Do's

• Use quick filters - Fast way to find recent changes
• Export important snapshots - Create backups of working states
• Search descriptions - Find specific changes quickly
• Review before jumping - Click "View Files" to see what will change
• Clear old history - Periodically clean up to save disk space

❌ Don'ts

• Don't rely solely on Time Machine - Still use proper version control (Git) for team projects
• Don't track large files - The extension stores complete file contents
• Don't delete .history_machine - You'll lose all your history
• Don't jump during unsaved work - Save your work first to avoid losing changes

🛠️ Troubleshooting

Snapshots Not Appearing

Problem: Changes aren't being captured

Solutions:

• Ensure you have a workspace/folder open (not just individual files)
• Check that the file is in the workspace (not an external file)
• Verify the extension is activated (check status bar or extension list)

Timeline Empty After Jump

Problem: After jumping to a snapshot, the timeline appears empty

Solutions:

• Click the "Refresh" button in the timeline
• Close and reopen the Time Machine panel
• Restart VS Code if the issue persists

Large Disk Usage

Problem: .history_machine folder is taking too much space

Solutions:

• Click "Clear All" to remove old snapshots
• Exclude large files/folders from your workspace
• Export important snapshots then clear history

Jump Fails

Problem: Error when trying to jump to a snapshot

Solutions:

• Ensure no files are currently being edited
• Close all open editors
• Check that .history_machine folder exists and is readable
• Try refreshing the timeline

🔐 Privacy & Security

• Local only - All data stays on your machine
• No cloud sync - Nothing is sent to external servers
• No telemetry - The extension doesn't track or report usage
• Full control - You can delete all history anytime
