Typeout

Replay file content character by character to create realistic undo history in VS Code & Antigravity IDE.

Why Typeout?

When presenting code demos, submitting assignments, or recording screencasts, having realistic editor typing history is essential. Manually copying and pasting drops an entire block into the editor as a single event, leaving zero typing history.

Typeout reads a reference backup file and types it into your active editor character by character. Every keystroke is its own independent undo stop, so pressing Ctrl+Z (or Cmd+Z) smoothly un-types your code in reverse order, exactly as if it was written by hand.

Features

• Character-by-Character Insertion: Each letter, tab, and newline is inserted sequentially with its own undo stop.
• Zero Drift & Clean Formatting: Automatically normalizes line endings (\r\n / \n) to prevent duplicate newlines and unwanted blank lines.
• Smooth Viewport Follow: The editor cursor and viewport automatically follow the typing head in real time.
• Progress Tracking & Cancellation: Shows a progress bar with percentage and character count, with instant cancellation support.
• No External Dependencies: Uses pure VS Code extension APIs—fast, lightweight, and reliable.

How to Use

1. Prepare your source file (e.g. main.cpp).
2. Create a backup file in the same directory with _backup appended before the extension:

   my-project/
   ├── main.cpp
   └── main_backup.cpp
   

3. Open main.cpp in the editor.
4. Press Ctrl+Shift+P (or Cmd+Shift+P on macOS) to open the Command Palette.
5. Search and run:

   Typeout: Type Current File Letter by Letter
   

6. Confirm the character count dialog and click Start.
7. Watch your code type itself out smoothly! Once done, you can press Ctrl+Z to step backward through the typing history letter by letter.
