VS Code-like Profile Setup for Neovim

This configuration implements a VS Code-like "profiles" system where language-specific plugins and tools only load when working with their respective file types.

🎯 Architecture

File Structure

~/.config/nvim/
├── init.lua                          # Main config with shared LSP, Treesitter, etc.
└── lua/
    └── custom/
        └── plugins/
            ├── init.lua              # Common plugins (Copilot, Neo-tree)
            ├── flutter.lua           # Flutter/Dart profile
            ├── python.lua            # Python profile
            └── svelte.lua            # Svelte/Web profile

How It Works

• lazy.nvim loads plugins based on file types (ft = { 'dart', 'python', 'svelte' })
• When you open a .dart file → Flutter tools load
• When you open a .py file → Python tools load
• When you open a .svelte file → Svelte tools load
• Common plugins (Copilot, Neo-tree) are always available

📦 What's Included

Common (All Profiles)

• GitHub Copilot: AI pair programming
• Neo-tree: File explorer (commented out, enable if desired)
• Telescope: Fuzzy finder
• Treesitter: Syntax highlighting
• blink.cmp: Autocompletion engine
• lua_ls: LSP for Neovim config editing

Flutter Profile (flutter.lua)

Loads on: .dart files

Tools:

• flutter-tools.nvim: Flutter development tools
• dartls: Dart LSP server
• Widget guides, closing tags, hot reload

Keymaps (under <leader>f):

• <leader>fr - Flutter run
• <leader>fq - Flutter quit
• <leader>fR - Flutter restart
• <leader>fd - Flutter devices
• <leader>fe - Flutter emulators
• <leader>fo - Flutter outline
• <leader>fc - Copy profiler URL
• <leader>fl - Restart LSP

Python Profile (python.lua)

Loads on: .py files

Tools:

• pyright: Python LSP server with type checking
• ruff_format: Fast Python formatter
• ruff_organize_imports: Import sorting
• Alternative: black + isort (commented out)

Format on save: Enabled for Python files

Svelte Profile (svelte.lua)

Loads on: .svelte, .ts, .js files

Tools:

• svelte-language-server: Svelte LSP
• ts_ls: TypeScript/JavaScript LSP
• tailwindcss: Tailwind CSS LSP with completions
• prettier: Code formatter for web files
• emmet-vim: HTML/CSS abbreviation expansion

Keymaps:

• <C-e>, - Expand Emmet abbreviation (e.g., div.container → full HTML)

Treesitter parsers: svelte, typescript, tsx, javascript, css, html, json

🚀 Installation Steps

1. Restart Neovim

nvim

2. Install Plugins

Once Neovim opens, lazy.nvim should automatically start installing plugins. If not:

:Lazy sync

Wait for all plugins to install. This may take a few minutes.

3. Install LSP Servers & Tools

:Mason

Press g? for help. Verify these are installed:

• Flutter: dart-language-server (dartls)
• Python: pyright, ruff, black (optional), isort (optional)
• Svelte: svelte-language-server, typescript-language-server, tailwindcss-language-server, prettier
• Common: lua-language-server, stylua

Mason will auto-install most of these via mason-tool-installer.

4. Install Treesitter Parsers

Parsers should auto-install when you open files. To manually install:

:TSInstall dart python svelte typescript tsx javascript css html json

Check status:

:TSInstallInfo

5. Test Each Profile

Test Flutter Profile

nvim test.dart

Inside Neovim:

• Type some Dart code (e.g., void main() {)
• Check LSP is active: :LspInfo
• Try hot reload keymaps if in a Flutter project: <leader>fr

Test Python Profile

nvim test.py

Inside Neovim:

• Type some Python code (e.g., def hello():)
• Check LSP is active: :LspInfo
• Save file to trigger auto-formatting
• Try hover: K on a function/variable

Test Svelte Profile

nvim test.svelte

Inside Neovim:

• Type Svelte component code
• Check LSP is active: :LspInfo
• Try Emmet: type div.container>ul>li*3 then <C-e>,
• Save file to trigger prettier formatting

🔧 Configuration Details

Node.js for Copilot

Node.js is configured via fnm (Fast Node Manager):

• Path: ~/.local/share/fnm/aliases/default/bin
• Version: Currently v24.11.0 LTS
• Auto-update: Using fnm aliases, so updating Node.js via fnm install --lts will automatically work

To update Node.js:

fnm install --lts
fnm default lts-latest

Shared LSP Capabilities

All language-specific LSPs use shared capabilities from blink.cmp for consistent completion behavior. This is configured automatically.

Format on Save

Enabled by default for all languages except C/C++. Language-specific formatters are defined in their respective profile files.

To disable for a specific file type, edit init.lua:

local disable_filetypes = { c = true, cpp = true, python = true } -- example

📝 Customization

Adding a New Language Profile

1. Create lua/custom/plugins/mylang.lua:

return {
  {
    'neovim/nvim-lspconfig',
    ft = { 'mylang' }, -- file type trigger
    config = function()
      local capabilities = require('blink.cmp').get_lsp_capabilities()
      require('lspconfig').mylang_ls.setup {
        capabilities = capabilities,
      }
    end,
  },
  
  {
    'stevearc/conform.nvim',
    ft = { 'mylang' },
    opts = {
      formatters_by_ft = {
        mylang = { 'my_formatter' },
      },
    },
  },
  
  {
    'nvim-treesitter/nvim-treesitter',
    ft = { 'mylang' },
    opts = {
      ensure_installed = { 'mylang' },
    },
  },
}

2. Restart Neovim and open a .mylang file

Enabling Neo-tree

The file tree is currently commented out. To enable:

Edit lua/custom/plugins/init.lua and uncomment the Neo-tree section:

return {
  {
    'nvim-neo-tree/neo-tree.nvim',
    -- ... (uncomment the entire block)
  },
}

Then :Lazy sync and use <leader>e to toggle the file tree.

Changing Keymaps

Edit the respective language file in lua/custom/plugins/.

Example: Change Flutter hot reload from <leader>fr to <leader>h:

-- In lua/custom/plugins/flutter.lua
vim.keymap.set('n', '<leader>h', '<cmd>FlutterRun<cr>', { desc = '[H]ot reload' })

🐛 Troubleshooting

Plugins not loading

:Lazy check
:Lazy sync

LSP not working

:LspInfo          " Check if LSP is attached
:Mason            " Verify servers are installed
:checkhealth lsp  " Run LSP diagnostics

Copilot not working

:Copilot setup    " Initial setup (if not done)
:Copilot status   " Check connection

If Node.js path issues:

# Verify Node.js is in fnm default alias
ls ~/.local/share/fnm/aliases/default/bin/node

Formatter not running on save

Check if formatter is installed:

:Mason

Check if file type has formatter configured:

:ConformInfo

Treesitter parsers missing

:TSInstall <parser_name>
# Or install all at once:
:TSInstall dart python svelte typescript tsx javascript css html json

3. Try Emmet: Speed up HTML/Svelte writing with abbreviations
4. Customize: Add more keymaps, plugins, or language profiles as needed
5. Consider Neo-tree: Uncomment if you prefer a file explorer sidebar

Enjoy your VS Code-like Neovim setup! 🚀
