scroll-keeper

Keep your focus on the same point as you resize panes. This package intelligently maintains your scroll position during window resizing, pane splitting, and soft-wrap changes. Integrates with smooth-scroll package (if installed).

• Smart Scroll Preservation: Maintains the cursor's visual position in the viewport during resize operations
• Copied Text-Editor: Copied text editors get's correct position of parent Text Editor.
• Soft-Wrap Awareness: Automatically adjusts scroll position when soft-wrap recalculates
• Debounced Recalculation: Reduces CPU usage during resize by waiting until you finish resizing (configurable delay)
• Smooth-Scroll Integration: Works seamlessly with the smooth-scroll package

Installation

To install scroll-keeper search for scroll-keeper in the Install pane of the Pulsar settings or run ppm install scroll-keeper. Alternatively, you can run ppm install asiloisad/pulsar-scroll-keeper to install a package directly from the GitHub repository.

How It Works

The package works best when soft-wrap is enabled, as this is when screen position differs from buffer position. When you resize a pane or split the editor:

1. Before resize: Records the cursor's position relative to the viewport top
2. During resize: Debounces soft-wrap recalculation to improve performance
3. After resize: Restores position so the cursor stays at the same visual location
