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.
NvChad is a Neovim configuration framework written in Lua that provides a modular, lazy-loaded base setup for Neovim. It enhances the editor with UI improvements (statusline, tabufline, theme picker), plugin management via lazy.nvim, and integrations for LSP, treesitter, telescope, and other popular plugins. The codebase is organized into distinct modules for options, mappings, autocommands, and plugin configurations, allowing users to import it as a plugin and override settings as needed. Key features include fast startup times (~0.02-0.07s), 93% lazy loading of plugins, and a focus on aesthetic UI components like NvCheatsheet and modern theme picker. The project is actively maintained with recent commits and demonstrates strong engineering practices for Neovim Lua configuration.
SQLua.nvim is a Neovim plugin that transforms the editor into a SQL IDE. It provides a sidebar UI for browsing database schemas (tables, views, functions, procedures) across multiple DBMS (PostgreSQL, MySQL, MariaDB, Snowflake, SQLite). Connections are configured via a JSON file with JDBC-like URLs. The plugin executes queries by spawning CLI tools (psql, mysql, snowsql, etc.) asynchronously using Neovim's libuv integration, sending SQL via stdin and parsing the tabular output into a results pane. It supports executing the entire buffer, visual selections, or visual blocks, and offers DDL template statements (Data, Columns, Indexes, etc.) that generate queries on click. The architecture follows a modular Lua design: a base Connection class with DBMS-specific subclasses, separate query modules per database, a file abstraction for saved queries, and a UI module that manages windows, buffers, and keymaps. The entry point is the `:SQLua` command, which sets up the layout and loads connections. The plugin relies solely on Neovim 0.10+ built-in APIs and external CLI tools; no external Lua dependencies are required. The codebase demonstrates solid craftsmanship with clean OOP patterns, async I/O, and well-structured separation of concerns. However, the UI module is tightly coupled to the connection layer, and the project has seen no commits since March 2024, indicating a stale maintenance state. The core utility functions, particularly the JDBC URL parser in utils.lua, are self-contained and could be reused in other Lua projects.
