🛠️ Customization

Adding Language Servers

Edit the LSP configuration to add more language servers:

lua

-- In ~/.config/nvim/lua/plugins/lsp.lua
local servers = {
  -- Add your language servers here
  pyright = {},        -- Python
  tsserver = {},       -- TypeScript/JavaScript  
  rust_analyzer = {},  -- Rust
  gopls = {},          -- Go
}

Custom Keybindings

Add your own keybindings to ~/.config/nvim/lua/user/keymaps.lua:

lua

-- Your custom mappings
map('n', '<leader>mm', ':MyCustomCommand<CR>', { desc = 'My custom command' })

Plugin Configuration

Modify plugin configurations in ~/.config/nvim/lua/plugins/:

colorscheme.lua - Theme settings
telescope.lua - Search configuration
git.lua - Git tool settings
lsp.lua - Language server settings

🐛 Troubleshooting

Common Issues

LSP Not Working:

bash

# Check Mason installation
:Mason
# Install language server manually
:MasonInstall lua-language-server

Plugins Not Loading:

bash

# Check lazy.nvim status
:Lazy
# Sync all plugins
:Lazy sync

Git Integration Issues:

bash

# Ensure git tools are available
which git delta difft
# Check git configuration
git config --list | grep -E "(core.pager|diff.external)"

Performance Issues

Slow Startup:

bash

# Check startup time
nvim --startuptime startup.log
# Profile plugins
:Lazy profile

Large Files:

LSP automatically disables for files >40k lines
Treesitter handles large files gracefully
Use :set syntax=off for very large files

🔒 Rollback Strategy

Immediate Rollback

bash

# Switch back to original immediately
./scripts/toggle-neovim.sh original

Emergency Recovery

bash

# Restore from backup if something goes wrong
./scripts/restore.sh neovim
# Or restore latest backup manually
cp -r ~/backups/nvim-backup-* ~/.config/nvim

Clean Installation

bash

# Start fresh if needed
rm -rf ~/.local/share/nvim/lazy
./scripts/toggle-neovim.sh enhanced
# Plugins will reinstall on next startup

📈 Benefits You'll Experience

Immediate Improvements

LSP Integration: Instant go-to-definition and documentation
Better Completion: Context-aware code completion

🎓 Advanced Usage

Project-Specific Configuration

Create project-specific settings with .nvim.lua files:

lua

-- .nvim.lua in project root
vim.opt_local.colorcolumn = "120"
vim.keymap.set('n', '<leader>r', ':!npm run dev<CR>')

Custom Snippets

Add your own snippets to enhance productivity:

lua

-- In lua/snippets/
local ls = require("luasnip")
local s = ls.snippet
local t = ls.text_node

ls.add_snippets("javascript", {
  s("log", t("console.log()"))
})

Integration with External Tools

The enhanced configuration integrates seamlessly with:

Claude Code: F-key shortcuts and clipboard integration
Tmux: Smart window navigation between vim and tmux
Git Tools: Delta, difftastic, and modern git workflows
Modern CLI Tools: Integration with bat, fd, ripgrep from Phase 2

🚀 Next Steps

Explore Features: Start with basic LSP and Telescope
Learn Gradually: Master one feature at a time
Customize: Add your own keybindings and preferences
Integrate: Combine with Phase 1 & 2 features for complete workflow

Phase 3 represents a significant leap forward in editing capabilities while maintaining the familiar, efficient workflow you've built. The safety-first approach ensures you can always return to your original setup while exploring these powerful new features.
