## 🤖 Quick Setup Guide

Telert supports multiple notification services. Choose one or more based on your needs:

### Telegram Setup

Telegram is the original and most fully featured provider for Telert. It uses official Bot API with reliable delivery.

1. **Create Bot**: Chat with `@BotFather` in Telegram, send `/newbot`, follow prompts and save your token
2. **Initialize**: Send any message to your new bot
3. **Get Chat ID**: Run `curl -s "https://api.telegram.org/bot<YOUR_TOKEN>/getUpdates"` and find your chat ID
4. **Configure**:

```bash
telert config telegram --token "<token>" --chat-id "<chat-id>" --set-default
telert status  # Test your configuration
```

[**Detailed Telegram Setup Guide**](https://github.com/navig-me/telert/blob/main/TELEGRAM.md)

### Microsoft Teams Setup

Teams integration uses Power Automate (Microsoft Flow) to deliver notifications to any Teams channel.

1. **Create Flow**: Use Power Automate to create an HTTP trigger flow that posts to Teams
2. **Configure**:

```bash
telert config teams --webhook-url "<flow-http-url>" --set-default
telert status  # Test your configuration
```

[**Detailed Microsoft Teams Setup Guide**](https://github.com/navig-me/telert/blob/main/TEAMS.md)

### Slack Setup

Slack integration uses incoming webhooks to deliver notifications to channels or direct messages.

1. **Create Webhook**: Create app at api.slack.com → Incoming Webhooks → Add to Workspace
2. **Configure**:

```bash
telert config slack --webhook-url "<webhook-url>" --set-default
telert status  # Test your configuration
```

[**Detailed Slack Setup Guide**](https://github.com/navig-me/telert/blob/main/SLACK.md)

### Pushover Setup

Pushover (Android & iOS) provides simple mobile notifications to your Android and iOS devices with a one-time purchase app.

1. **Create Account**: Sign up at [pushover.net](https://pushover.net/) to get your user key
2. **Create App**: Create an application at pushover.net to get your app token
3. **Configure**:

```bash
telert config pushover --token "<app-token>" --user "<user-key>" --set-default
telert status  # Test your configuration
```

[**Detailed Pushover Setup Guide**](https://github.com/navig-me/telert/blob/main/PUSHOVER.md)

### Audio Alerts Setup

Play a sound notification when your command completes.

```bash
# Basic installation
pip install telert

# Install with audio dependencies (optional, for playsound support)
pip install telert[audio]

# Configure with default sound (uses platform-specific audio players)
telert config audio --set-default
telert status  # Test your configuration

# Or with custom sound file
telert config audio --sound-file "/path/to/alert.wav" --volume 0.8 --set-default
```

Audio notifications work on:
- **macOS**: Uses built-in `afplay` command (supports MP3 and WAV)
- **Linux**: Tries `mpg123` (for MP3s), `paplay` (PulseAudio), or `aplay` (ALSA)
- **Windows**: 
  - For WAV files: Uses built-in `winsound` module
  - For MP3 files: Tries `playsound` library (install with `pip install telert[audio]`)

Telert includes a built-in MP3 notification sound, so you don't need to provide your own sound file.

### Desktop Notifications Setup

Show notifications in your operating system's notification center.

```bash
# Configure with default icon
telert config desktop --app-name "My App" --set-default
telert status  # Test your configuration

# Or with custom icon
telert config desktop --app-name "My App" --icon-path "/path/to/icon.png" --set-default
```

Desktop notifications work on:
- **macOS**: 
  - Uses AppleScript with sound alert to improve visibility
  - On newer macOS versions (Catalina+), you may need to grant notification permissions:
    - Go to System Preferences → Notifications → Terminal (or iTerm2) and enable notifications
  - Alternative: Install `terminal-notifier` (`brew install terminal-notifier`) as a fallback
- **Linux**: Uses `notify-send` (install with `sudo apt install libnotify-bin` on Debian/Ubuntu)
- **Windows**: Uses PowerShell on Windows 10+

Telert includes a built-in notification icon, so you don't need to provide your own icon.

### Managing Multiple Providers

Telert lets you configure multiple providers with enhanced flexibility:

```bash
# List configured providers
telert status

# Set a provider as default
telert config telegram --token "<your-token>" --chat-id "<your-chat-id>" --set-default

# Set multiple default providers in priority order
telert config set-defaults --providers "slack,desktop,audio"

# When configuring a provider, add it to existing defaults
telert config audio --sound-file "/path/to/sound.mp3" --add-to-defaults

# Use a specific provider rather than default
telert send --provider desktop "Via desktop notification"

# Send to multiple providers at once
telert send --provider "slack,telegram" "Multi-provider message"

# Send to all configured providers
telert send --all-providers "Important message to all channels"

# Python API for defaults
from telert import set_default_provider, set_default_providers
set_default_provider("audio")  # Single provider
set_default_providers(["slack", "desktop"])  # Multiple providers in priority order

# Python API for sending
from telert import send
send("Message to default provider(s)")
send("Message to specific provider", provider="telegram")
send("Message to multiple providers", provider=["slack", "audio"])
send("Message to all providers", all_providers=True)
```

Telert securely stores all configuration in `~/.config/telert/config.json` but supports environment variable overrides for all settings.

## ✨ Features

| Mode           | What it does | Example |
|----------------|--------------|---------|
| **Run**        | Wraps a command, times it, sends notification with exit code. | `telert run --label "RSYNC" -- rsync -a /src /dst` |
| **Filter**     | Reads from stdin so you can pipe command output. | `long_job \| telert "compile done"` |
| **Hook**       | Generates a Bash snippet so **every** command > *N* seconds notifies automatically. | `eval "$(telert hook -l 30)"` |
| **Send**       | Low-level "send arbitrary text" helper. | `telert send --provider slack "Build complete"` |
| **Python API** | Use directly in Python code with context managers and decorators. | `from telert import telert, send, notify` |
| **Multi-provider** | Configure and use multiple notification services (Telegram, Teams, Slack, Pushover, Audio, Desktop). | `telert config desktop --app-name "My App"` |

---

## 📋 Usage Guide

### Command Line Interface (CLI)

> **Note**: When using the `run` command, do not use double dashes (`--`) to separate telert options from the command to run. The correct syntax is `telert run [options] command`, not `telert run [options] -- command`.

#### Run Mode
Wrap any command to receive a notification when it completes:

```bash
# Basic usage - notify when command finishes (uses default provider)
telert run npm run build

# Add a descriptive label
telert run --label "DB Backup" pg_dump -U postgres mydb > backup.sql

# Show notification only when a command fails
telert run --only-fail rsync -av /src/ /backup/

# Send to a specific provider
telert run --provider teams --label "ML Training" python train_model.py

# Send to multiple specific providers
telert run --provider "slack,telegram" --label "CI Build" make all

# Send to all configured providers
telert run --all-providers --label "Critical Backup" backup.sh

# Custom notification message
telert run --message "Training complete! 🎉" python train_model.py

# Run in silent mode (output only in notification, not displayed in terminal)
TELERT_SILENT=1 telert run python long_process.py
```

Command output is shown in real-time by default. Use `TELERT_SILENT=1` environment variable if you want to capture output for the notification but not display it in the terminal.

#### Filter Mode
Perfect for adding notifications to existing pipelines:

```bash
# Send notification when a pipeline completes (uses default provider)
find . -name "*.log" | xargs grep "ERROR" | telert "Error check complete"

# Process and notify with specific provider
cat large_file.csv | awk '{print $3}' | sort | uniq -c | telert --provider slack "Data processing finished"

# Send to multiple providers
find /var/log -name "*.err" | grep -i "critical" | telert --provider "telegram,desktop" "Critical errors found"

# Send to all providers
backup.sh | telert --all-providers "Database backup complete"
```

> **Note:** In filter mode, the exit status is not captured since commands in a pipeline run in separate processes.
> For exit status tracking, use Run mode or add explicit status checking in your script.

#### Send Mode
Send custom messages from scripts to any provider:

```bash
# Simple text message (uses default provider(s))
telert send "Server backup completed"

# Send to a specific provider
telert send --provider teams "Build completed"
telert send --provider slack "Deployment started"

# Send to multiple specific providers at once
telert send --provider "telegram,slack,desktop" "Critical alert!"

# Send to all configured providers
telert send --all-providers "System restart required"

# Show details of message delivery with verbose flag
telert send --all-providers --verbose "Message sent to all providers"

# Send status from a script
if [ $? -eq 0 ]; then
  telert send "✅ Deployment successful"
else
  # Send failure notification to all providers
  telert send --all-providers "❌ Deployment failed with exit code $?"
fi
```

#### Shell Hook
Get notifications for ALL commands that take longer than a certain time:

```bash
# Configure Bash to notify for any command taking longer than 30 seconds
eval "$(telert hook -l 30)"

# Add to your .bashrc for persistent configuration
echo 'eval "$(telert hook -l 30)"' >> ~/.bashrc
```

#### CLI Help
```bash
# View all available commands
telert --help

# Get help for a specific command
telert run --help
```

### Using Shell Built-ins with telert

When using `telert run` with shell built-in commands like `source`, you'll need to wrap them in a bash call:

```bash
# This will fail
telert run source deploy.sh

# This works
telert run bash -c "source deploy.sh"
```

For convenience, we provide a wrapper script that automatically handles shell built-ins:

```bash
# Download the wrapper script
curl -o ~/bin/telert-wrapper https://raw.githubusercontent.com/navig-me/telert/main/telert-wrapper.sh
chmod +x ~/bin/telert-wrapper

# Now you can use shell built-ins directly
telert-wrapper run source deploy.sh
```

### Python API

#### Configuration
```python
from telert import (
    configure_telegram, configure_teams, configure_slack, configure_pushover,
    configure_audio, configure_desktop, configure_providers,
    set_default_provider, set_default_providers, 
    is_configured, get_config, list_providers
)

# Configure one or more providers
configure_telegram("<token>", "<chat-id>")
configure_teams("<webhook-url>")
configure_slack("<webhook-url>")
configure_pushover("<app-token>", "<user-key>")
configure_audio()  # Uses built-in sound
# Or with custom sound: configure_audio("/path/to/alert.wav", volume=0.8)

# Configure provider and add to existing defaults (without replacing them)
configure_desktop("My App", add_to_defaults=True)  # Uses built-in icon

# Configure multiple providers at once
configure_providers([
    {"provider": "telegram", "token": "<token>", "chat_id": "<chat-id>"},
    {"provider": "slack", "webhook_url": "<webhook-url>"},
    {"provider": "audio"}
], set_as_defaults=True)  # Optionally set these as defaults in the given order

# Check if specific provider is configured
if not is_configured("audio"):
    configure_audio("/path/to/bell.wav")

# Get configuration for a specific provider
desktop_config = get_config("desktop")
print(f"Using app name: {desktop_config['app_name']}")

# List all providers and see which is default
providers = list_providers()
for p in providers:
    print(f"{p['name']} {'(default)' if p['is_default'] else ''}")

# Set a single default provider
set_default_provider("audio")

# Set multiple default providers in priority order
set_default_providers(["slack", "desktop", "audio"])
```

#### Simple Messaging
```python
from telert import send

# Send using default provider(s)
send("Script started")  # Uses default providers in configured priority order

# Send to specific provider
send("Processing completed with 5 records updated", provider="teams")

# Send to multiple specific providers
send("Critical error detected!", provider=["slack", "telegram"])

# Send to all configured providers
send("Major system error", all_providers=True)

# Provider-specific examples
send("Send to mobile device", provider="pushover")
send("Play a sound alert", provider="audio")
send("Show a desktop notification", provider="desktop")

# Check delivery results
results = send("Important message", provider=["slack", "telegram"])
for provider, success in results.items():
    if not success:
        print(f"Failed to send to {provider}")
```

#### Context Manager
The `telert` context manager times code execution and sends a notification when the block completes:

```python
from telert import telert
import time

# Basic usage
with telert("Data processing"):
    # Your long-running code here
    time.sleep(5)

# Include results in the notification
with telert("Calculation") as t:
    result = sum(range(1000000))
    t.result = {"sum": result, "status": "success"}

# Only notify on failure
with telert("Critical operation", only_fail=True):
    # This block will only send a notification if an exception occurs
    risky_function()
    
# Specify a provider
with telert("Teams notification", provider="teams"):
    # This will notify via Teams regardless of the default provider
    teams_specific_operation()
    
# Send to multiple providers
with telert("Important calculation", provider=["slack", "telegram"]):
    # This will send to both Slack and Telegram
    important_calculation()
    
# Send to all configured providers
with telert("Critical operation", all_providers=True):
    # This will send to all configured providers
    critical_function()
    
# Use audio notifications
with telert("Long calculation", provider="audio"):
    # This will play a sound when done
    time.sleep(5)
    
# Use desktop notifications
with telert("Database backup", provider="desktop"):
    # This will show a desktop notification when done
    backup_database()
    
# Send to mobile device
with telert("Long-running task", provider="pushover"):
    # This will send to Pushover when done
    time.sleep(60)
```

#### Function Decorator
The `notify` decorator makes it easy to monitor functions:

```python
from telert import notify

# Basic usage - uses function name as the label
@notify()
def process_data():
    # Code that might take a while
    return "Processing complete"

# Custom label and only notify on failure
@notify("Database backup", only_fail=True)
def backup_database():
    # This will only send a notification if it raises an exception
    return "Backup successful"

# Function result will be included in the notification
@notify("Calculation")
def calculate_stats(data):
    return {"mean": sum(data)/len(data), "count": len(data)}

# Send notification to specific provider
@notify("Slack alert", provider="slack")
def slack_notification_function():
    return "This will be sent to Slack"
    
# Send to multiple providers
@notify("Important function", provider=["telegram", "desktop"])
def important_function():
    return "This will be sent to both Telegram and Desktop"
    
# Send to all configured providers
@notify("Critical function", all_providers=True)
def critical_function():
    return "This will be sent to all providers"
    
# Use audio notifications
@notify("Audio alert", provider="audio")
def play_sound_on_completion():
    return "This will play a sound when done"
    
# Use desktop notifications
@notify("Desktop alert", provider="desktop")
def show_desktop_notification():
    return "This will show a desktop notification when done"
    
# Send to mobile device
@notify("Mobile alert", provider="pushover")
def send_mobile_notification():
    return "This will send to Pushover when done"
```

## 🌿 Environment Variables

### Configuration Variables

| Variable                  | Effect                                      |
|---------------------------|---------------------------------------------|
| `TELERT_DEFAULT_PROVIDER` | Set default provider(s) to use (comma-separated for multiple) |
| `TELERT_TOKEN` or `TELERT_TELEGRAM_TOKEN` | Telegram bot token         |
| `TELERT_CHAT_ID` or `TELERT_TELEGRAM_CHAT_ID` | Telegram chat ID       |
| `TELERT_TEAMS_WEBHOOK`    | Microsoft Teams Power Automate HTTP URL     |
| `TELERT_SLACK_WEBHOOK`    | Slack webhook URL                           |
| `TELERT_PUSHOVER_TOKEN`   | Pushover application token                  |
| `TELERT_PUSHOVER_USER`    | Pushover user key                           |
| `TELERT_AUDIO_FILE`       | Path to sound file for audio notifications  |
| `TELERT_AUDIO_VOLUME`     | Volume level for audio notifications (0.0-1.0) |
| `TELERT_DESKTOP_APP_NAME` | Application name for desktop notifications  |
| `TELERT_DESKTOP_ICON`     | Path to icon file for desktop notifications |

### Runtime Variables

| Variable          | Effect                                            |
|-------------------|---------------------------------------------------|
| `TELERT_LONG`     | Default threshold (seconds) for `hook`            |
| `TELERT_SILENT=1` | Capture and include command output in notification, but don't display in real-time |

### Example Usage

```bash
# Set multiple default providers (will use in fallback order)
export TELERT_DEFAULT_PROVIDER="slack,audio,desktop"

# Configure Telegram via environment
export TELERT_TELEGRAM_TOKEN="your-bot-token"
export TELERT_TELEGRAM_CHAT_ID="your-chat-id"

# Configure Slack
export TELERT_SLACK_WEBHOOK="https://hooks.slack.com/services/..."

# Configure desktop notifications
export TELERT_DESKTOP_APP_NAME="MyApp"

# Send a message (will use default providers in order)
telert send "Environment variable configuration works!"
```

Using environment variables is especially useful in CI/CD pipelines or containerized environments where you don't want to create a config file. Environment variables take precedence over the configuration file, making them perfect for temporary overrides.

## 💡 Use Cases and Tips

### Server Administration
- Get notified when backups complete
- Monitor critical system jobs
- Alert when disk space runs low

```bash
# Alert when disk space exceeds 90%
df -h | grep -E '[9][0-9]%' | telert "Disk space alert!"

# Monitor a system update
telert run --label "System update" apt update && apt upgrade -y
```

### Data Processing
- Monitor long-running data pipelines
- Get notified when large file operations complete
- Track ML model training progress

```python
from telert import telert, notify
import pandas as pd

@notify("Data processing")
def process_large_dataset(filename):
    df = pd.read_csv(filename)
    # Process data...
    return {"rows_processed": len(df), "outliers_removed": 15}
```

### CI/CD Pipelines
- Get notified when builds complete
- Alert on deployment failures
- Track test suite status

```bash
# In a CI/CD environment using environment variables
export TELERT_TOKEN="your-token"
export TELERT_CHAT_ID="your-chat-id"
