This is a Neovim plugin that animates the cursor with a smear effect, inspired by Neovide's animated cursor. It works in any terminal by using floating windows and Unicode block characters to render a smooth, physics-based trailing cursor. The plugin listens to cursor movement events and interpolates the cursor position using a spring-damper system, drawing the smear as a quad with sub-cell precision. It supports configurable stiffness, damping, particles, and various rendering modes (vertical bar, horizontal bar, diagonal blocks, braille). The codebase is modular, with clear separation between animation logic, drawing, color management, and event handling. The drawing module is particularly noteworthy for its sophisticated use of Unicode symbols to achieve anti-aliased-like rendering in a terminal environment.
