# Task Management System

A tmux-based task scheduling and monitoring tool with support for concurrent execution, real-time monitoring, email notifications, and more.

## Features

- 🚀 Concurrent execution of multiple tasks
- 📊 Real-time monitoring and status viewing
- 🛠️ System resource monitoring (CPU, memory, disk)
- 📝 Automatic log management
- 📧 Email notifications (optional)
- 🔧 Simple configuration management

## Quick Start

### Step 1: Install

```bash
# Install from PyPI
pip install lite-slurm

# Or install from source
git clone <repository-url>
cd slurm-like-task-manager
pip install -e .
```

**Requirements:** Python 3.7+ and tmux (install with `sudo apt-get install tmux` or `brew install tmux`)

### Step 2: Initialize

```bash
task config init
```

### Step 3: Run Your First Task

```bash
# Run a task
task run "My Task" "python my_script.py"

# List tasks
task list

# Monitor task output
task monitor <task_id>

# Stop task
task kill <task_id>

# Clean a task
task cleanup <task_id>
```

That's it! You're ready to use the task manager.

## Installation

### From PyPI

```bash
pip install lite-slurm
task config init
```

### From Source

```bash
git clone <repository-url>
cd slurm-like-task-manager
pip install -r requirements.txt
pip install -e .
task config init
```

### System Requirements

- Python 3.7+
- tmux (install: `sudo apt-get install tmux` / `brew install tmux`)

## Usage

### Basic Commands

```bash
# Run task
task run "Task Name" "command to execute"

# List tasks
task list                          # All tasks
task list --status running         # Filter by status
task list --resources              # Show system resources

# Monitor task
task monitor <task_id>            # Real-time monitoring
task monitor <task_id> --lines 100 # Show last 100 lines

# Stop task
task kill <task_id>               # Stop single task
task kill <task_id1> <task_id2>   # Stop multiple tasks
task kill --all                   # Stop all running tasks
task kill <task_id> --force       # Force stop (immediate kill)

# View task info
task status <task_id>             # Task status
task output <task_id>             # Task output
task logs <task_id>               # Task logs

# Cleanup
task cleanup                      # Clean tasks older than 24h
task cleanup 12                   # Clean tasks older than 12h
```

### Examples

```bash
# Run training task
task run "Model Training" "python train.py --epochs 100"

# Run multiple tasks concurrently
task run "Data Processing" "python process_data.py"
task run "Feature Extraction" "python extract_features.py"

# Monitor and manage
task list --resources
task monitor 00001
task kill 00001 00002 00003       # Kill multiple tasks
```

## Configuration

### Email Notifications (Optional)

To enable email notifications:

1. **Create email config** (`~/.task_manager/config/email_config.json`):
   ```json
   {
       "enabled": true,
       "to_email": "your-email@example.com"
   }
   ```

2. **Setup Google API credentials**:
   - Get credentials from [Google Cloud Console](https://console.cloud.google.com/)
   - Enable Gmail API and create OAuth 2.0 credentials
   - Save as `~/.task_manager/config/credentials.json`

3. **Get Gmail token**:
   ```bash
   task config google_api login
   ```

**Quick import** (if you have existing files):
```bash
task config email ~/email_config.json
task config token ~/token.json
task config google_api file ~/credentials.json
```

### Configuration Commands

```bash
task config init                  # Initialize config
task config show                  # Show current config
task config test                  # Test email config
task config email <file>          # Import email config
task config token <file>          # Import token
task config google_api file <file> # Import credentials
task config google_api login      # Login to get token
```

## Command Reference

## File Structure

```
~/.task_manager/
├── config/
│   ├── email_config.json    # Email configuration
│   ├── credentials.json     # Google API credentials
│   └── token.json           # Gmail token
├── logs/                    # Task log files
│   └── <task_id>.log
└── tasks.json               # Task database
```

## Troubleshooting

- **tmux not found**: Install with `sudo apt-get install tmux` or `brew install tmux`
- **Permission denied**: Check script execute permissions
- **Email not working**: Verify Gmail API config and token validity
- **Task not starting**: Check for tmux session name conflicts

Logs location: `~/.task_manager/logs/<task_id>.log`

## Uninstallation

```bash
pip uninstall lite-slurm
rm -rf ~/.task_manager
