# Python Setup & IDE Guide

Short, clear, Python‑focused.

---

## Requirements

- **Python 3.10+**  
Uses pattern matching, modern type hints, async improvements.

```bash
python --version
```

---

## IDE Setup (PyCharm / IntelliJ)

1. **Set interpreter:**  
   *File → Settings → Project → Python Interpreter → Select Python 3.10+*

2. **Fix syntax warnings:**  
   *Editor → Inspections → Python → Set language level to 3.10+*

3. **Ensure correct SDK:**  
   *Project Structure → Project SDK → Python 3.10+*

---

## Installation

```bash
# Activate venv
~\venvs\scaev\Scripts\Activate.ps1

# Install deps
pip install -r requirements.txt

# Playwright browsers
playwright install chromium
```

---

## Database Configuration (PostgreSQL)

The scraper now uses PostgreSQL (no more SQLite files). Configure via `DATABASE_URL`:

- Default (baked in):
  `postgresql://auction:heel-goed-wachtwoord@192.168.1.159:5432/auctiondb`
- Override for your environment:

```bash
# Windows PowerShell
$env:DATABASE_URL = "postgresql://user:pass@host:5432/dbname"

# Linux/macOS
export DATABASE_URL="postgresql://user:pass@host:5432/dbname"
```

Packages used:
- Driver: `psycopg[binary]`

Nothing is written to local `.db` files anymore.

---

## Verify

```bash
python -c "import sys; print(sys.version)"
python main.py --help
```

Common fixes:

```bash
pip install playwright
playwright install chromium
```

---

# Auto‑Start (Monitor)

## Linux (systemd) — Recommended

```bash
cd ~/scaev
chmod +x install_service.sh
./install_service.sh
```

Service features:
- Auto‑start
- Auto‑restart
- Logs: `~/scaev/logs/monitor.log`

```bash
sudo systemctl status scaev-monitor
journalctl -u scaev-monitor -f
```

---

## Windows (Task Scheduler)

```powershell
cd C:\vibe\scaev
.\setup_windows_task.ps1
```

Manage:

```powershell
Start-ScheduledTask "ScaevAuctionMonitor"
```

---

# Cron Alternative (Linux)

```bash
crontab -e
@reboot cd ~/scaev && python3 src/monitor.py 30 >> logs/monitor.log 2>&1
0 * * * * pgrep -f monitor.py || (cd ~/scaev && python3 src/monitor.py 30 >> logs/monitor.log 2>&1 &)
```

---

# Status Checks

```bash
ps aux | grep monitor.py
tasklist | findstr python
```

---

# Troubleshooting

- Wrong interpreter → Set Python 3.10+
- Multiple monitors running → kill extra processes
- PostgreSQL connectivity → verify `DATABASE_URL`, network/firewall, and credentials
- Service fails → check `journalctl -u scaev-monitor`

---

# Java Extractor (Short Version)

Prereqs: **Java 21**, **Maven**

Install:

```bash
mvn clean install
mvn exec:java -Dexec.mainClass=com.microsoft.playwright.CLI -Dexec.args="install"
```

Run:

```bash
mvn exec:java -Dexec.args="--max-visits 3"
```

Enable native access (IntelliJ → VM Options):

```
--enable-native-access=ALL-UNNAMED
```
