## Dependency Management

This project uses [uv](https://docs.astral.sh/uv/) for dependency management. The `uv.lock` file is committed to ensure reproducible builds.

### Adding or Updating Dependencies

1. Edit `pyproject.toml` to add/update dependencies
2. Run `uv lock` to update the lockfile with new dependency resolution
3. Run `uv sync` to install the updated dependencies locally
4. Always commit both files together:
   ```bash
   git add pyproject.toml uv.lock
   git commit -m "feat: add new dependency for feature X"
   ```

**Important:** Never manually edit `uv.lock`. It's auto-generated by `uv lock`.

## Code Style and Documentation

### Python Code Style

We use Ruff for code linting and formatting. Please ensure your code passes all linting checks before submitting a PR.

### Docstring Conventions

We follow Google-style docstrings with these specific conventions:

**Regular Classes:**

- Class docstring describes the class purpose and key functionality
- `__init__` method has its own docstring with complete `Args:` section documenting all parameters
- All public methods must have docstrings with `Args:` and `Returns:` sections as appropriate

**Dataclasses:**

- Class docstring describes the purpose and documents all fields in a `Parameters:` section
- No `__init__` docstring (auto-generated)

**Properties:**

- Must have docstrings with `Returns:` section

**Abstract Methods:**

- Must have docstrings explaining what subclasses should implement

**`__init__.py` Files:**

- **Skip docstrings** for pure import/re-export modules
- **Add brief docstrings** for top-level packages or those with initialization logic

**Enums:**

- Class docstring describes the enumeration purpose
- Use `Parameters:` section to document each enum value and its meaning
- No `__init__` docstring (Enums don't have custom constructors)

**Code Examples in Docstrings:**

- Use `Examples:` as a section header for multiple examples
- Use descriptive text followed by double colons (`::`) for each example
- **Always include a blank line after the `::"`**
- Indent all code consistently within each block
- Separate multiple examples with blank lines for readability

**Lists and Bullets in Docstrings:**

- Use dashes (`-`) for bullet points, not asterisks (`*`)
- **Add a blank line before bullet lists** when they follow a colon
- Use section headers like "Supported features:" or "Behavior:" before lists
- For complex nested information, consider using paragraph format instead

**Deprecations:**

- Use `warnings.warn()` in code for runtime deprecation warnings
- Add `.. deprecated::` directive in docstrings for documentation visibility
- Include version information and describe current status
- Describe parameters in present tense, use directive to indicate deprecation status

#### Examples:

```python
# Regular class
class MyService(BaseService):
    """Description of what the service does.

    Provides detailed explanation of the service's functionality,
    key features, and usage patterns.

    Supported features:

    - Feature one with detailed explanation
    - Feature two with additional context
    - Feature three for advanced use cases
    """

    def __init__(self, param1: str, old_param: str = None, **kwargs):
        """Initialize the service.

        Args:
            param1: Description of param1.
            old_param: Controls legacy behavior.

                .. deprecated:: 1.2.0
                    This parameter no longer has any effect and will be removed in version 2.0.

            **kwargs: Additional arguments passed to parent.
        """
        if old_param is not None:
            import warnings
            warnings.warn(
                "Parameter 'old_param' is deprecated and will be removed in version 2.0.",
                DeprecationWarning,
            )
        super().__init__(**kwargs)

    @property
    def sample_rate(self) -> int:
        """Get the current sample rate.

        Returns:
            The sample rate in Hz.
        """
        return self._sample_rate

    async def process_data(self, data: str) -> bool:
        """Process the provided data.

        Args:
            data: The data to process.

        Returns:
            True if processing succeeded.
        """
        pass

# Dataclass with code examples
@dataclass
class MessageFrame:
    """Frame containing messages in OpenAI format.

    Supports both simple and content list message formats.

    Example::

        [
            {"role": "user", "content": "Hello"},
            {"role": "assistant", "content": "Hi there!"}
        ]

    Parameters:
        messages: List of messages in OpenAI format.
    """

    messages: List[dict]

# Enum class
class Status(Enum):
    """Status codes for processing operations.

    Parameters:
        PENDING: Operation is queued but not started.
        RUNNING: Operation is currently in progress.
        COMPLETED: Operation finished successfully.
        FAILED: Operation encountered an error.
    """

    PENDING = "pending"
    RUNNING = "running"
    COMPLETED = "completed"
    FAILED = "failed"

response to any behavior that they deem inappropriate, threatening, offensive,
or harmful.

Community leaders have the right and responsibility to remove, edit, or reject
comments, commits, code, wiki edits, issues, and other contributions that are
not aligned to this Code of Conduct, and will communicate reasons for moderation
decisions when appropriate.

## Scope

This Code of Conduct applies within all community spaces, and also applies when
an individual is officially representing the community in public spaces.
Examples of representing our community include using an official email address,
posting via an official social media account, or acting as an appointed
representative at an online or offline event.

## Enforcement

Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported to the community leaders responsible for enforcement at pipecat-ai@daily.co.
All complaints will be reviewed and investigated promptly and fairly.

All community leaders are obligated to respect the privacy and security of the
reporter of any incident.

## Enforcement Guidelines

Community leaders will follow these Community Impact Guidelines in determining
the consequences for any action they deem in violation of this Code of Conduct:

### 1. Correction

**Community Impact**: Use of inappropriate language or other behavior deemed
unprofessional or unwelcome in the community.

**Consequence**: A private, written warning from community leaders, providing
clarity around the nature of the violation and an explanation of why the
behavior was inappropriate. A public apology may be requested.

### 2. Warning

**Community Impact**: A violation through a single incident or series of
actions.

**Consequence**: A warning with consequences for continued behavior. No
interaction with the people involved, including unsolicited interaction with
those enforcing the Code of Conduct, for a specified period of time. This
includes avoiding interactions in community spaces as well as external channels
like social media. Violating these terms may lead to a temporary or permanent
ban.

### 3. Temporary Ban

**Community Impact**: A serious violation of community standards, including
sustained inappropriate behavior.

**Consequence**: A temporary ban from any sort of interaction or public
communication with the community for a specified period of time. No public or
private interaction with the people involved, including unsolicited interaction
with those enforcing the Code of Conduct, is allowed during this period.
Violating these terms may lead to a permanent ban.

### 4. Permanent Ban

**Community Impact**: Demonstrating a pattern of violation of community
standards, including sustained inappropriate behavior, harassment of an
individual, or aggression toward or disparagement of classes of individuals.

**Consequence**: A permanent ban from any sort of public interaction within the
community.
