|
||||||
|
|
||||||
|
**macOS (using Homebrew):**
|
||||||
|
```bash
|
||||||
|
brew install neovim
|
||||||
|
```
|
||||||
|
|
||||||
|
**Verify installation:**
|
||||||
|
```bash
|
||||||
|
nvim --version
|
||||||
|
# Should show v0.10.0 or higher
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 2. External Dependencies
|
||||||
|
|
||||||
|
**Required Tools:**
|
||||||
|
```bash
|
||||||
|
# macOS installation
|
||||||
|
brew install git make gcc ripgrep fd
|
||||||
|
```
|
||||||
|
|
||||||
|
**Java Development:**
|
||||||
|
```bash
|
||||||
|
# Install Java (if not already installed)
|
||||||
|
brew install openjdk@21
|
||||||
|
|
||||||
|
# Verify Java installation
|
||||||
|
java --version
|
||||||
|
```
|
||||||
|
|
||||||
|
**Optional but Recommended:**
|
||||||
|
- **Nerd Font** for icons: `brew install font-jetbrains-mono-nerd-font`
|
||||||
|
- **Clipboard tool**: Built-in on macOS (pbcopy/pbpaste)
|
||||||
|
|
||||||
|
### Installation Steps
|
||||||
|
|
||||||
|
#### Step 1: Backup Existing Configuration
|
||||||
|
|
||||||
|
If you have an existing Neovim configuration:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Backup your current config
|
||||||
|
mv ~/.config/nvim ~/.config/nvim.backup.$(date +%Y%m%d_%H%M%S)
|
||||||
|
|
||||||
|
# Backup your data directory
|
||||||
|
mv ~/.local/share/nvim ~/.local/share/nvim.backup.$(date +%Y%m%d_%H%M%S)
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Step 2: Install kickstart.nvim
|
||||||
|
|
||||||
|
**For personal use (Recommended):**
|
||||||
|
|
||||||
|
1. **Fork the repository:**
|
||||||
|
- Go to: https://github.com/advpetc/kickstart.nvim
|
||||||
|
- Click "Fork" button (top right)
|
||||||
|
- This creates a copy under your GitHub account
|
||||||
|
|
||||||
|
2. **Clone your fork:**
|
||||||
|
```bash
|
||||||
|
# Replace <your_github_username> with your actual username
|
||||||
|
git clone https://github.com/<your_github_username>/kickstart.nvim.git ~/.config/nvim
|
||||||
|
```
|
||||||
|
|
||||||
|
**Or clone directly (not recommended for long-term use):**
|
||||||
|
```bash
|
||||||
|
git clone https://github.com/advpetc/kickstart.nvim.git ~/.config/nvim
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Step 3: Apply Java IDE Enhancements
|
||||||
|
|
||||||
|
The Java enhancements are already included in this repository. If you're setting up from scratch:
|
||||||
|
|
||||||
|
1. **The `init.lua` file already contains:**
|
||||||
|
- jdtls configuration (lines 743-828)
|
||||||
|
- Java, Groovy, Kotlin Treesitter parsers (line 988)
|
||||||
|
- google-java-format configuration (line 775)
|
||||||
|
- Nerd Font enabled (line 94)
|
||||||
|
- Relative line numbers (line 103)
|
||||||
|
|
||||||
|
2. **No additional configuration needed** - everything is ready to use!
|
||||||
|
|
||||||
|
#### Step 4: First Launch
|
||||||
|
|
||||||
|
```bash
|
||||||
|
nvim
|
||||||
|
```
|
||||||
|
|
||||||
|
**What happens on first launch:**
|
||||||
|
1. ✓ lazy.nvim plugin manager installs automatically
|
||||||
|
2. ✓ All 22 plugins download (~116MB, takes 1-2 minutes)
|
||||||
|
3. ✓ Treesitter parsers compile
|
||||||
|
4. ✓ Mason installs LSP servers (jdtls, lua_ls)
|
||||||
|
5. ✓ Native extensions build (telescope-fzf, LuaSnip)
|
||||||
|
|
||||||
|
**You'll see:**
|
||||||
|
```
|
||||||
|
lazy.nvim
|
||||||
|
● nvim-lspconfig ... ✓
|
||||||
|
● telescope.nvim ... ✓
|
||||||
|
● nvim-treesitter ... ✓
|
||||||
|
[... 19 more plugins ...]
|
||||||
|
```
|
||||||
|
|
||||||
|
Press `q` to close the Lazy window when installation completes.
|
||||||
|
|
||||||
|
#### Step 5: Install Nerd Font (for icons)
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Install JetBrainsMono Nerd Font
|
||||||
|
brew install font-jetbrains-mono-nerd-font
|
||||||
|
```
|
||||||
|
|
||||||
|
**Configure your terminal:**
|
||||||
|
|
||||||
|
- **macOS Terminal:**
|
||||||
|
1. Terminal → Preferences (Cmd+,)
|
||||||
|
2. Profiles → Font → Change
|
||||||
|
3. Select "JetBrainsMono Nerd Font Mono"
|
||||||
|
4. Close and reopen Terminal
|
||||||
|
|
||||||
|
- **iTerm2:**
|
||||||
|
1. iTerm2 → Settings (Cmd+,)
|
||||||
|
2. Profiles → Text → Font
|
||||||
|
3. Select "JetBrainsMono Nerd Font Mono"
|
||||||
|
4. Restart iTerm2
|
||||||
|
|
||||||
|
#### Step 6: Test Java Features
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Open a test Java file
|
||||||
|
nvim /tmp/TestJava.java
|
||||||
|
```
|
||||||
|
|
||||||
|
Type this in the file:
|
||||||
|
```java
|
||||||
|
public class TestJava {
|
||||||
|
public static void main(String[] args) {
|
||||||
|
System.out.println("Hello World");
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Wait 5-10 seconds** for jdtls to start, then:
|
||||||
|
|
||||||
|
1. Run `:LspInfo` - Should show "Client: java"
|
||||||
|
2. Put cursor on `println` and press `K` - Shows documentation
|
||||||
|
3. Press `grd` on `println` - Jumps to definition
|
||||||
|
4. Press `<Space>f` - Formats the code
|
||||||
|
|
||||||

### Verification
|
||||||
|
|
||||||
|
After installation, verify everything works:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Check Neovim installation
|
||||||
|
nvim --version
|
||||||
|
|
||||||
|
# Check Java
|
||||||
|
java --version
|
||||||
|
|
||||||
|
# Check dependencies
|
||||||
|
which git make gcc rg fd
|
||||||
|
|
||||||
|
# Open Neovim
|
||||||
|
nvim
|
||||||
|
|
||||||
|
# Inside Neovim, run:
|
||||||
|
:checkhealth
|
||||||
|
```
|
||||||
|
|
||||||
|
The `:checkhealth` command will show the status of all components. Look for:
|
||||||
|
- ✓ Neovim version
|
||||||
|
- ✓ Git available
|
||||||
|
- ✓ ripgrep installed
|
||||||
|
- ✓ LSP servers installed
|
||||||
|
- ✓ Treesitter parsers installed
|
||||||
|
|
||||||
|
### Post-Installation
|
||||||
|
|
||||||
|
#### Configure Git (if needed)
|
||||||
|
```bash
|
||||||
|
git config --global user.name "Your Name"
|
||||||
|
git config --global user.email "your.email@example.com"
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Track Plugin Versions (Recommended)
|
||||||
|
```bash
|
||||||
|
cd ~/.config/nvim
|
||||||
|
# Remove lazy-lock.json from .gitignore to track plugin versions
|
||||||
|
git rm --cached lazy-lock.json
|
||||||
|
git add lazy-lock.json
|
||||||
|
git commit -m "Track plugin lock file"
|
||||||
|
```
|
||||||
|
|
||||||
|
### Alternative: Multiple Configurations
|
||||||
|
|
||||||
|
You can keep multiple Neovim configurations using `NVIM_APPNAME`:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Install kickstart to a separate location
|
||||||
|
git clone https://github.com/advpetc/kickstart.nvim.git ~/.config/nvim-kickstart
|
||||||
|
|
||||||
|
# Create an alias
|
||||||
|
echo 'alias nvim-kick="NVIM_APPNAME=nvim-kickstart nvim"' >> ~/.zshrc
|
||||||
|
source ~/.zshrc
|
||||||
|
|
||||||
|
# Use the alternative config
|
||||||
|
nvim-kick # Uses ~/.config/nvim-kickstart
|
||||||
|
nvim # Uses ~/.config/nvim (your default)
|
||||||
|
```
|
||||||
|
|
||||||
|
## 🔧 Configuration Changes
|
||||||
|
|
||||||
|
### 1. Java LSP Setup (init.lua:743-828)
|
||||||
|
|
||||||
|
**Added dedicated jdtls configuration:**
|
||||||
|
```lua
|
||||||
|
{
|
||||||
|
'neovim/nvim-lspconfig',
|
||||||
|
ft = { 'java' },
|
||||||
|
config = function()
|
||||||
|
-- Auto-starts jdtls when opening .java files
|
||||||
|
-- Creates unique workspace for each project
|
||||||
|
-- Configures proper Java command-line arguments
|
||||||
|
end,
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Key features:**
|
||||||
|
- Workspace directory: `~/.local/share/nvim/jdtls-workspace/<project-name>/`
|
||||||
|
- Auto-detects project root (git, Maven, Gradle)
|
||||||
|
- Memory allocation: 1GB heap size
|
||||||

|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. Mason Tools (init.lua:720-722)
|
||||||
|
|
||||||
|
**Added Java tools:**
|
||||||
|
```lua
|
||||||
|
ensure_installed = {
|
||||||
|
'stylua',
|
||||||
|
'jdtls', -- Java Language Server
|
||||||
|

|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4. Code Formatting (init.lua:773-781)
|
||||||
|
|
||||||
|

|
||||||
|
```
|
||||||
|
|
||||||
|
## 🚦 Getting Started
|
||||||
|
|
||||||
|
### First Launch
|
||||||
|
```bash
|
||||||
|
nvim
|
||||||
|
```
|
||||||
|
|
||||||
|
On first launch, Neovim will:
|
||||||
|
1. Install lazy.nvim plugin manager
|
||||||
|
2. Download all 22 plugins (~116MB)
|
||||||
|
3. Build native extensions (fzf, LuaSnip)
|
||||||
|
4. Install Mason tools (jdtls, formatters)
|
||||||
|
|
||||||
|
**This takes 1-2 minutes on first run.**
|
||||||
|
|
||||||
|
### Opening Java Files
|
||||||
|
```bash
|
||||||
|
cd your-java-project
|
||||||
|
nvim src/main/java/com/example/Main.java
|
||||||
|
```
|
||||||
|
|
||||||
|
**Wait 5-10 seconds** for jdtls to:
|
||||||
|
- Start the Language Server
|
||||||
|
- Index your project
|
||||||
|
- Enable LSP features
|
||||||
|
|
||||||
|
**Check status:**
|
||||||
|
```vim
|
||||||
|
:LspInfo
|
||||||
|
```
|
||||||
|
Should show: `Client: java (id: 1, bufnr: [1])`
|
||||||
|
|
||||||
|
### Testing LSP Features
|
||||||
|
|
||||||
|
**Try these in order:**
|
||||||
|
1. Put cursor on a method call → Press `grd` → Jump to definition
|
||||||
|
2. Press `K` over any method → Show documentation
|
||||||
|
3. Put cursor on a variable → Press `grr` → Find all references
|
||||||
|
4. Press `<Space>sf` → Search for files
|
||||||
|
5. Press `<Space>sg` → Search text in project
|
||||||
|
|
||||||
|
## 🔍 Troubleshooting
|
||||||
|
|
||||||
|
### LSP Not Working
|
||||||
|
|
||||||
|
**Check if jdtls is installed:**
|
||||||
|
```vim
|
||||||
|
:Mason
|
||||||
|
```
|
||||||
|
Look for "jdtls" in the list.
|
||||||
|
|
||||||
|
**Check LSP status:**
|
||||||
|
```vim
|
||||||
|
:LspInfo
|
||||||
|
```
|
||||||
|
|
||||||
|
**Restart LSP:**
|
||||||
|
```vim
|
||||||
|
:LspRestart
|
||||||
|
```
|
||||||
|
|
||||||
|
**Check for errors:**
|
||||||
|
```vim
|
||||||
|
:messages
|
||||||
|
```
|
||||||
|
|
||||||
|
### Java Features Not Available
|
||||||
|
|
||||||
|
**Symptoms:**
|
||||||
|
- "method not supported" errors
|
||||||
|
- No auto-completion
|
||||||
|
- `grr` doesn't work
|
||||||
|
|
||||||
|
**Solutions:**
|
||||||
|
1. **Wait** - First indexing takes 10-30 seconds
|
||||||
|
2. **Check file type:** `:set filetype?` should show `filetype=java`
|
||||||
|
3. **Verify jdtls running:** `:LspInfo` should show "Client: java"
|
||||||
|
4. **Large projects** - First indexing can take 30-60 seconds
|
||||||
|
|
||||||
|
### Nerd Font Icons Missing
|
||||||
|
|
||||||
|
**Symptoms:** Boxes/squares instead of icons
|
||||||
|
|
||||||
|
**Solution:**
|
||||||
|
1. Install Nerd Font: `brew install font-jetbrains-mono-nerd-font`
|
||||||
|
2. Configure terminal to use "JetBrainsMono Nerd Font Mono"
|
||||||
|
3. Restart terminal
|
||||||
|
4. Reopen Neovim
|
||||||
|
|
||||||
|
**Or disable icons:**
|
||||||
|
```lua
|
||||||
|
vim.g.have_nerd_font = false -- in init.lua line 94
|
||||||
|
```
|
||||||
|
|
||||||
|
### Treesitter Error
|
||||||
|
|
||||||
|
**If you see:** `Failed to run config for nvim-treesitter`
|
||||||
|
|
||||||
|
**Already fixed in init.lua:982-999** - Uses `config = function()` instead of `main` parameter.

## 📝 Customization
|
||||||
|
|
||||||
|
### Change Color Scheme
|
||||||
|
Edit `init.lua` line 897:
|
||||||
|
```lua
|
||||||
|
vim.cmd.colorscheme 'tokyonight-night' -- or tokyonight-storm, tokyonight-moon, tokyonight-day
|
||||||
|
```
|
||||||
|
|
||||||
|
### Disable Format on Save
|
||||||
|
Edit `init.lua` line 759-771:
|
||||||
|
```lua
|
||||||
|
format_on_save = nil, -- Change from function to nil
|
||||||
|
```
|
||||||
|
|
||||||
|
### Add More LSP Servers
|
||||||
|
Edit `init.lua` line 687-725:
|
||||||
|
```lua
|
||||||
|
local servers = {
|
||||||
|
-- Add your server here
|
||||||
|
pyright = {}, -- Python
|
||||||
|
ts_ls = {}, -- TypeScript
|
||||||
|
gopls = {}, -- Go
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Add Custom Keybindings
|
||||||
|
Add after line 200 in `init.lua`:
|
||||||
|
```lua
|
||||||
|
vim.keymap.set('n', '<Tab>', ':bnext<CR>', { desc = 'Next buffer' })
|
||||||
|
vim.keymap.set('n', '<S-Tab>', ':bprev<CR>', { desc = 'Previous buffer' })
|
||||||
|
```
|
||||||
|
|
||||||
|
## 📊 Performance
|
||||||
|
|
||||||
|
### Startup Time
|
||||||
|
- **Cold start**: ~200-300ms
|
||||||
|
- **With plugins**: ~250-350ms
|
||||||
|
- **With LSP**: +100-200ms (first file)
|
||||||
|
|
||||||
|
### Memory Usage
|
||||||
|
- **Base Neovim**: ~50MB
|
||||||
|
- **With plugins loaded**: ~80-100MB
|
||||||
|
- **With jdtls active**: ~150-200MB
|
||||||
|
- **Large Java projects**: ~300-500MB
|
||||||
|
|
||||||
|
### Indexing Time
|
||||||
|
- **Small project** (<1000 files): 5-10 seconds
|
||||||
|
- **Medium project** (<10k files): 20-30 seconds
|
||||||
|
- **Large project** (>10k files): 30-60 seconds
|
||||||
|
|
||||||
|
**Note:** Indexing is cached. Subsequent opens are much faster (2-3 seconds).

|
## 🐛 Known Issues
|
||||||
|
|
||||||
|
1. **First Java file open is slow** - jdtls needs to start and index (normal behavior)
|
||||||
|
2. **Large projects may freeze briefly** - Initial indexing is CPU intensive
|
||||||
|
3. **Import organization** - Requires manual trigger with code action (`gra`)
|
||||||
