## Installation

Install from PyPI:

```bash
pip install phtnai-logger
```

Or using Poetry:

```bash
poetry add phtnai-logger
```

## Quick Start

```python
from phtnai_logger import Logger

# Create a logger
logger = Logger("my-service")

# Log messages
logger.info("Application started")
logger.warning("This is a warning")
logger.error("An error occurred")

# Add context
logger.set_context("user_id", "user123")
logger.set_context("request_id", "req456")

# Log with context
logger.info("User action performed")

# Clear context
logger.clear_context()
```

## Configuration

Configure via environment variables:

```bash
export PHTNAI_LOGGER_NAME="my-service"
export PHTNAI_LOGGER_LEVEL="DEBUG"
export PHTNAI_LOG_FILE="/var/log/app.log"
```

Or programmatically:

```python
from phtnai_logger.config import LoggerConfig

config = LoggerConfig(
    name="my-service",
    level="DEBUG",
    log_file="/var/log/app.log"
)
```

## JSON Logging

Use JSON formatter for structured logs:

```python
import logging
from phtnai_logger import Logger
from phtnai_logger.utils.formatter import JSONFormatter

logger = Logger("my-service")
handler = logging.StreamHandler()
formatter = JSONFormatter()
handler.setFormatter(formatter)
logger._logger.addHandler(handler)

logger.info("User logged in", user_id="user123")
```

## Cloud-Native Logging with Fluent Bit

For containerized environments (Docker/Kubernetes), use stdout logging to enable automatic log capture:

```python
from phtnai_logger import Logger

# Create logger
logger = Logger("my-service")

# Setup stdout logging (JSON format for log aggregators)
logger.setup_stdout_logging(json_format=True)

# All logs go to stdout
logger.info("Payment processed", user_id="u123", amount=99.99)
# Output: {"timestamp": "...", "level": "INFO", "message": "Payment processed", ...}
```

**Fluent Bit Configuration**:
```ini
[INPUT]
    Name              tail
    Path              /var/log/containers/*.log
    Parser            docker
    Tag               container.*

[FILTER]
    Name       parser
    Match      container.*
    Key_Name   log
    Parser     json

[OUTPUT]
    Name  es
    Match *
    Host  elasticsearch:9200
```

**Benefits**:
- ✅ No file I/O overhead
- ✅ Container-native logging pattern
- ✅ Fluent Bit automatically captures stdout
- ✅ Works with ELK, Datadog, CloudWatch, Splunk

See [Fluent Bit Integration Guide](docs/FLUENT_BIT_INTEGRATION.md) for Docker/Kubernetes examples.

## Development

### Setup

```bash
# Clone repository
git clone https://github.com/phtnai/phtnai-logger.git
cd phtnai-logger

# Install with development dependencies
poetry install

# Install pre-commit hooks
pre-commit install
```

### Testing

```bash
# Run all tests
poetry run pytest

# Run with coverage
poetry run pytest --cov=src --cov-report=html

# Run specific test file
poetry run pytest tests/unit/test_core.py
```

### Code Quality

```bash
# Format code
poetry run black src tests

# Sort imports
poetry run isort src tests

# Lint code
poetry run flake8 src tests

# Type checking
poetry run mypy src
```

### Building

```bash
# Build distribution
poetry build

# The wheel will be in dist/ directory
```

## CI/CD Pipeline

This project uses GitHub Actions for:

1. **Testing**: Runs on Python 3.9-3.12 on every push/PR
2. **Linting**: Black, isort, flake8, mypy checks
3. **Publishing**: Automated semantic versioning and PyPI publishing

### Version Bumping

Versions are bumped automatically based on commit messages:

- `fix: ...` → PATCH version (0.0.X)
- `feat: ...` → MINOR version (0.X.0)
- `BREAKING CHANGE: ...` → MAJOR version (X.0.0)

**Example**:
```bash
git commit -m "feat: add custom formatter support"
git push origin main
# Automatically bumps version and publishes to PyPI
```

### Publishing

To publish to PyPI, add `PYPI_API_TOKEN` secret to GitHub repository settings.
