Module Review: Modern Vim

[!NOTE] This module explores the core principles of Module Review: Modern Vim, deriving solutions from first principles and hardware constraints to build world-class, production-ready expertise.

Consolidate your learning of the modern Neovim ecosystem and prepare for advanced configuration.

1. Key Takeaways

  1. Lua is King: Neovim’s embedded LuaJIT allows for high-performance configuration and plugins, replacing the slow and obscure Vimscript.
  2. Built-in LSP: You don’t need heavy plugins for IDE features anymore. Neovim’s native LSP client communicates directly with language servers for definition, hover, and diagnostics.
  3. Modern Plugins: lazy.nvim has revolutionized package management by ensuring plugins are only loaded when needed, keeping startup times under 50ms.
  4. Modular Config: Stop using a single 1000-line .vimrc. Structure your config in lua/user/ modules and require() them.
