### Naming Conventions

```
Container Script:      ct/AppName.sh
Installation Script:   install/appname-install.sh
Defaults:             defaults/appname.vars
Update Script:        /usr/bin/update (inside container)

Examples:
  ct/pihole.sh                → install/pihole-install.sh
  ct/docker.sh                → install/docker-install.sh
  ct/nextcloud-vm.sh          → install/nextcloud-vm-install.sh
```

**Rules**:
- Container script name: **Title Case** (PiHole, Docker, NextCloud)
- Install script name: **lowercase** with **hyphens** (pihole-install, docker-install)
- Must match: `ct/AppName.sh` ↔ `install/appname-install.sh`
- Directory names: lowercase (always)
- Variable names: lowercase (except APP constant)

---

## Development Setup

### Prerequisites

1. **Proxmox VE 8.0+** with at least:
   - 4 CPU cores
   - 8 GB RAM
   - 50 GB disk space
   - Ubuntu 20.04 / Debian 11+ on host

2. **Git** installed
   ```bash
   apt-get install -y git
   ```

3. **Text Editor** (VS Code recommended)
   ```bash
   # VS Code extensions:
   # - Bash IDE
   # - Shellcheck
   # - Markdown All in One
   ```

### Local Development Workflow

#### Option A: Development Fork (Recommended)

```bash
# 1. Fork on GitHub (one-time)
# Visit: https://github.com/community-scripts/ProxmoxVED
# Click: Fork

# 2. Clone your fork
git clone https://github.com/YOUR_USERNAME/ProxmoxVED.git
cd ProxmoxVED

# 3. Add upstream remote for updates
git remote add upstream https://github.com/community-scripts/ProxmoxVED.git

# 4. Create feature branch
git checkout -b feat/add-myapp

# 5. Make changes
# ... edit files ...

# 6. Keep fork updated
git fetch upstream
git rebase upstream/main

# 7. Push and open PR
git push origin feat/add-myapp
```

#### Option B: Local Testing on Proxmox Host

```bash
# 1. SSH into Proxmox host
ssh root@192.168.1.100

# 2. Download your script
curl -O https://raw.githubusercontent.com/YOUR_USERNAME/ProxmoxVED/feat/myapp/ct/myapp.sh

# 3. Make it executable
chmod +x myapp.sh

# 4. Update URLs to your fork
# Edit: curl -s https://raw.githubusercontent.com/YOUR_USERNAME/ProxmoxVED/feat/myapp/...

# 5. Run and test
bash myapp.sh

# 6. If container created successfully, script is working!
```

#### Option C: Docker Testing (Without Proxmox)

```bash
# You can test script syntax/functionality locally
# Note: Won't fully test (no Proxmox, no actual container)

# Run ShellCheck
shellcheck ct/myapp.sh
shellcheck install/myapp-install.sh

# Syntax check
bash -n ct/myapp.sh
bash -n install/myapp-install.sh
```

## Creating New Applications

### Step 1: Choose Your Template

**For Simple Web Apps** (Node.js, Python, PHP):
```bash
cp ct/example.sh ct/myapp.sh
cp install/example-install.sh install/myapp-install.sh
```

**For Database Apps** (PostgreSQL, MongoDB):
```bash
cp ct/docker.sh ct/myapp.sh           # Use Docker container
# OR manual setup for more control
```

**For Alpine Linux Apps** (lightweight):
```bash
# Use ct/alpine.sh as reference
# Edit install script to use Alpine packages (apk not apt)
```

### Step 2: Update Container Script

**File**: `ct/myapp.sh`

```bash
#!/usr/bin/env bash
source <(curl -fsSL https://raw.githubusercontent.com/YOUR_USERNAME/ProxmoxVED/feat/myapp/misc/build.func)

# Update these:
APP="MyAwesomeApp"                    # Display name
var_tags="category;tag2;tag3"         # Max 3-4 tags
var_cpu="2"                          # Realistic CPU cores
var_ram="2048"                       # Min RAM needed (MB)
var_disk="10"                        # Min disk (GB)
var_os="debian"                      # OS type
var_version="12"                     # OS version
var_unprivileged="1"                 # Security (1=unprivileged)

header_info "$APP"
variables
color
catch_errors

function update_script() {
  header_info
  check_container_storage
  check_container_resources

  if [[ ! -d /opt/myapp ]]; then
    msg_error "No ${APP} Installation Found!"
    exit
  fi

  # Get latest version
  RELEASE=$(curl -fsSL https://api.github.com/repos/user/repo/releases/latest | \
    grep "tag_name" | awk '{print substr($2, 2, length($2)-3)}')

  if [[ ! -f /opt/${APP}_version.txt ]] || [[ "${RELEASE}" != "$(cat /opt/${APP}_version.txt)" ]]; then
    msg_info "Updating ${APP} to v${RELEASE}"
    # ... update logic ...
    echo "${RELEASE}" > /opt/${APP}_version.txt
    msg_ok "Updated ${APP}"
  else
    msg_ok "No update required. ${APP} is already at v${RELEASE}."
  fi
  exit
}

start
build_container
description

msg_ok "Completed Successfully!\n"
echo -e "${CREATING}${GN}${APP} setup has been successfully initialized!${CL}"
echo -e "${INFO}${YW} Access it using the following URL:${CL}"
echo -e "${TAB}${GATEWAY}${BGN}http://${IP}:PORT${CL}"
```

**Checklist**:
- [ ] APP variable matches filename
- [ ] var_tags semicolon-separated (no spaces)
- [ ] Realistic CPU/RAM/disk values
- [ ] update_script() implemented
- [ ] Correct OS and version
- [ ] Success message with access URL

### Step 3: Update Installation Script

**File**: `install/myapp-install.sh`

```bash
#!/usr/bin/env bash
# Copyright (c) 2021-2025 community-scripts ORG
# Author: YourUsername
# License: MIT
# Source: https://github.com/example/myapp

source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
color
verb_ip6
catch_errors
setting_up_container
network_check
update_os

msg_info "Installing Dependencies"
$STD apt-get install -y \
  curl \
  wget \
  git \
  build-essential
msg_ok "Installed Dependencies"

msg_info "Setting up Node.js"
NODE_VERSION="22" setup_nodejs
msg_ok "Node.js installed"

msg_info "Downloading Application"
cd /opt
wget -q "https://github.com/user/repo/releases/download/v1.0.0/myapp.tar.gz"
tar -xzf myapp.tar.gz
rm -f myapp.tar.gz
msg_ok "Application installed"

echo "1.0.0" > /opt/${APP}_version.txt

motd_ssh
customize
cleanup_lxc
```

**Checklist**:
- [ ] Functions loaded from `$FUNCTIONS_FILE_PATH`
- [ ] All installation phases present (deps, tools, app, config, cleanup)
- [ ] Using `$STD` for output suppression
- [ ] Version file saved
- [ ] Final cleanup with `cleanup_lxc`
- [ ] No hardcoded versions (use GitHub API)

### Step 4: Create ASCII Header (Optional)

**File**: `ct/headers/myapp`

```
╔═══════════════════════════════════════╗
║                                       ║
║          🎉 MyAwesomeApp 🎉          ║
║                                       ║
║  Your app is being installed...       ║
║                                       ║
╚═══════════════════════════════════════╝
```

Save in: `ct/headers/myapp` (no extension)

### Step 5: Create Defaults File (Optional)

**File**: `defaults/myapp.vars`

```bash
# Default configuration for MyAwesomeApp
var_cpu=4
var_ram=4096
var_disk=15
var_hostname=myapp-container
var_timezone=UTC
```

## Code Standards

### Bash Style Guide

#### Variable Naming

```bash
# ✅ Good
APP="MyApp"                 # Constants (UPPERCASE)
var_cpu="2"                # Configuration (var_*)
container_id="100"         # Local variables (lowercase)
DB_PASSWORD="secret"       # Environment-like (UPPERCASE)

# ❌ Bad
myapp="MyApp"              # Inconsistent
VAR_CPU="2"               # Wrong convention
containerid="100"         # Unclear purpose
```

#### Function Naming

```bash
# ✅ Good
function setup_database() { }       # Descriptive
function check_version() { }        # Verb-noun pattern
function install_dependencies() { } # Clear action

# ❌ Bad
function setup() { }                # Too vague
function db_setup() { }             # Inconsistent pattern
function x() { }                    # Cryptic
```

#### Quoting

```bash
# ✅ Good
echo "${APP}"                       # Always quote variables
if [[ "$var" == "value" ]]; then   # Use [[ ]] for conditionals
echo "Using $var in string"        # Variables in double quotes

# ❌ Bad
echo $APP                          # Unquoted variables
if [ "$var" = "value" ]; then      # Use [[ ]] instead
echo 'Using $var in string'        # Single quotes prevent expansion
```

#### Command Formatting

```bash
# ✅ Good: Multiline for readability
$STD apt-get install -y \
  package1 \
  package2 \
  package3

# ✅ Good: Complex commands with variables
if ! wget -q "https://example.com/${file}"; then
  msg_error "Failed to download"
  exit 1
fi

# ❌ Bad: Too long on one line
$STD apt-get install -y package1 package2 package3 package4 package5 package6

# ❌ Bad: No error checking
wget https://example.com/file
```

#### Error Handling

```bash
# ✅ Good: Check critical commands
if ! some_command; then
  msg_error "Command failed"
  exit 1
fi

# ✅ Good: Use catch_errors for automatic trapping
catch_errors

# ❌ Bad: Silently ignore failures
some_command || true
some_command 2>/dev/null

# ❌ Bad: Unclear what failed
if ! (cmd1 && cmd2 && cmd3); then
  msg_error "Something failed"
fi
```

# ✅ Good: Explain WHY, not WHAT
# Use alphanumeric only to avoid shell escaping issues
DB_PASS=$(openssl rand -base64 18 | tr -dc 'a-zA-Z0-9' | head -c13)

# ✅ Good: Comment complex logic
# Detect if running Alpine vs Debian for proper package manager
if grep -qi 'alpine' /etc/os-release; then
  PKG_MGR="apk"
else
  PKG_MGR="apt"
fi

# ❌ Bad: Comment obvious code

## Testing Your Changes

### Pre-Submission Testing

#### 1. Syntax Check

```bash
# Verify bash syntax
bash -n ct/myapp.sh
bash -n install/myapp-install.sh

# If no output: ✅ Syntax is valid
# If error output: ❌ Fix syntax before submitting
```

#### 2. ShellCheck Static Analysis

```bash
# Install ShellCheck
apt-get install -y shellcheck

# Check scripts
shellcheck ct/myapp.sh
shellcheck install/myapp-install.sh

# Review warnings and fix if applicable
# Some warnings can be intentional (use # shellcheck disable=...)
```

#### 3. Real Proxmox Testing

```bash
# Best: Test on actual Proxmox system

# 1. SSH into Proxmox host
ssh root@YOUR_PROXMOX_IP

# 2. Download your script
curl -O https://raw.githubusercontent.com/YOUR_USER/ProxmoxVED/feat/myapp/ct/myapp.sh

# 3. Make executable
chmod +x myapp.sh

# 4. UPDATE URLS IN SCRIPT to point to your fork
sed -i 's|community-scripts|YOUR_USER|g' myapp.sh

# 5. Run script
bash myapp.sh

# 6. Test interaction:
#    - Select installation mode
#    - Confirm settings
#    - Monitor installation

# 7. Verify container created
pct list | grep myapp

# 8. Log into container and verify app
pct exec 100 bash
```

#### 4. Edge Case Testing

```bash
# Test with different settings:

# Test 1: Advanced (19-step) installation
# When prompted: Select "2" for Advanced

# Test 2: User Defaults
# Before running: Create ~/.community-scripts/default.vars
# When prompted: Select "3" for User Defaults

# Test 3: Error handling
# Simulate network outage (block internet)
# Verify script handles gracefully

# Test 4: Update function
# Create initial container
# Wait for new release
# Run update: bash ct/myapp.sh
# Verify it detects and applies update
```

## Troubleshooting

### "Repository not found" when cloning

```bash
# Check your fork exists
# Visit: https://github.com/YOUR_USERNAME/ProxmoxVED

# If not there: Click "Fork" on original repo first
```

### "Permission denied" when pushing

```bash
# Setup SSH key
ssh-keygen -t ed25519 -C "your_email@example.com"
cat ~/.ssh/id_ed25519.pub  # Copy this

# Add to GitHub: Settings → SSH Keys → New Key

# Or use HTTPS with token:
git remote set-url origin https://YOUR_TOKEN@github.com/YOUR_USERNAME/ProxmoxVED.git
```

### Script syntax errors

```bash
# Use ShellCheck to identify issues
shellcheck install/myapp-install.sh

# Common issues:
# - Unmatched quotes: "string' or 'string"
# - Missing semicolons before then: if [...]; then
# - Wrong quoting: echo $VAR instead of echo "${VAR}"
```

### Container creation fails immediately

```bash
# 1. Check Proxmox resources
free -h              # Check RAM
df -h                # Check disk space
pct list            # Check CTID availability

# 2. Check script URL
# Make sure curl -s in script points to your fork

# 3. Review errors
# Run with verbose: bash -x ct/myapp.sh
```

### App not accessible after creation

```bash
# 1. Verify container running
pct list
pct status CTID

# 2. Check if service running inside
pct exec CTID systemctl status myapp

# 3. Check firewall
# Proxmox host: iptables -L
# Container: iptables -L

# 4. Verify listening port
pct exec CTID netstat -tlnp | grep LISTEN
```

## FAQ

### Q: Do I need to be a Bash expert?

**A**: No! The codebase has many examples you can copy. Most contributions are straightforward script creation following the established patterns.

### Q: Can I add a new application that's not open source?

**A**: No. ProxmoxVED focuses on open-source applications (GPL, MIT, Apache, etc.). Closed-source applications won't be accepted.

### Q: How long until my PR is reviewed?

**A**: Maintainers are volunteers. Reviews typically happen within 1-2 weeks. Complex changes may take longer.

### Q: Can I test without a Proxmox system?

**A**: Partially. You can verify syntax and ShellCheck compliance locally, but real container testing requires Proxmox. Consider using:
- Proxmox in a VM (VirtualBox/KVM)
- Test instances on Hetzner/DigitalOcean
- Ask maintainers to test for you

### Q: My update function is very complex - is that OK?

**A**: Yes! Update functions can be complex if needed. Just ensure:
- Backup user data before updating
- Restore user data after update
- Test thoroughly before submitting
- Add clear comments explaining logic

### Q: Can I add new dependencies to build.func?

**A**: Generally no. build.func is the orchestrator and should remain stable. New functions should go in:
- `tools.func` - Tool installation
- `core.func` - Utility functions
- `install.func` - Container setup

Ask in an issue first if you're unsure.

### Q: What if the application has many configuration options?

**A**: You have options:

**Option 1**: Use Advanced mode (19-step wizard)
```bash
# Extend advanced_settings() if app needs special vars
```

**Option 2**: Create custom setup menu
```bash
function custom_config() {
  OPTION=$(whiptail --inputbox "Enter database name:" 8 60)
  # ... use $OPTION in installation
}
```

**Option 3**: Leave as defaults + documentation
```bash
# In success message:
echo "Edit /opt/myapp/config.json to customize settings"
```

### Q: Can I contribute Windows/macOS/ARM support?

**A**:
- **Windows**: Not planned (ProxmoxVED is Linux/Proxmox focused)
- **macOS**: Can contribute Docker-based alternatives
- **ARM**: Yes! Many apps work on ARM. Add to vm/pimox-*.sh scripts
