vimrc (AI-Era Standalone Lightweight & High-Performance)

A modern, standalone, high-performance Vim & Neovim configuration.

Absorbed and modernized from amix/vimrc / vimrc-fork: sub-millisecond startup, instant file/content search via ripgrep & fd, NERDTree sidebar, lightning code reading & review, seamless system clipboard, precision text editing, and automated fast formatting.

Quick Start

1. Install system dependencies (ripgrep, fd, bat, fzf, vim, neovim):

   bash zsh.sh

2. Run full environment setup (interactively choose 1) Vim, 2) Neovim, or 3) Both):

   zsh setup.sh

What's Included

• Vim & Neovim Configuration (vimrc):
  • Dual Support: Works identically across standard Vim (~/.vimrc) and Neovim (~/.config/nvim/init.vim)
  • Plugin Management: vim-plug with auto-bootstrapping and parallel async downloads
  • File Tree Explorers: nvim-tree.lua (Neovim async tree) / fern.vim (Vim async tree) + oil.nvim (buffer-based file editor)
  • Syntax & Highlighting: vim-polyglot (lazy-loaded 100+ languages)
  • Git Workflow: vim-fugitive (status & interactive blame), vim-gitgutter, git-messenger.vim (popup commit info)
  • Precision Editing: vim-surround, vim-commentary, vim-repeat, vim-indent-object, vim-visual-multi, editorconfig
  • Formatters: ALE with modern fast linters/fixers (ruff, gofumpt, prettier, shfmt, rustfmt)
  • UI & Aesthetics: gruvbox true-color scheme, lightline.vim statusline, hybrid relative numbers
  • Neovim Enhancements: Live substitution preview (inccommand=split), terminal escape mappings
  • System Clipboard: Seamless copy/paste with OS and AI assistants (clipboard^=unnamed,unnamedplus)
  • Persistent Undo: Undo history survives editor restarts (~/.vim/temp_dirs/undodir)
• Zsh: oh-my-zsh, shell aliases (bat, ripgrep, fd, fzf, v, n), and fzf key-bindings
• Node.js: via fnm (Fast Node Manager) with pnpm
• Python: via uv (fast Python package manager) with ruff
• Rust: via rustup with optional rsproxy.cn mirror
• Go: with goimports and shfmt (installed to ~/sdk/go<version>)
• VSCode: editor settings (supports official VSCode, Insiders, VSCodium)
• Git: global gitignore configuration
