## Why Supersonic?

Modern AI and SaaS applications often need to propose changes to user repositories—whether it's AI-suggested improvements, automated documentation updates, or configuration changes. However, creating Pull Requests programmatically through the GitHub API can be complex and error-prone.

Supersonic solves this:

- **Simple, High-Level API**: Create PRs with a single function call, using files or plain text content
- **Safe Defaults**: All changes are created as PRs, allowing users to review before merging
- **Enterprise Ready**: Full support for GitHub Enterprise and custom base URLs
- **Excessively customizable**: Full control over PR creation, set draft mode, reviewers, labels, etc.
- **Best for apps, useful for scripts too**: Plug it into your SaaS app and delight your users. Or automate internal workflows.

Common use cases:
- AI applications suggesting code improvements
- Documentation generators keeping docs in sync with code
- Configuration management tools proposing config updates
- Any service that needs to propose changes to user repositories

We use this at [Cased](https://cased.com) to support our DevOps automations.

## Installation

```bash
# Using pip with uv (recommended)
uv pip install supersonic

# Development installation
git clone https://github.com/cased/supersonic
cd supersonic
uv venv
source .venv/bin/activate
uv pip install -r requirements-dev.txt
uv pip install -e .
```

## Quick Start

### Easiest Start

First an idea of what Supersonic can do. 

Say you just want to create a PR to update a file.
You can do this with `create_pr_from_content`, just by providing the content 
and the upstream file path where you want the content to go.

```python
from supersonic import Supersonic

my_supersonic = Supersonic("your-github-token")

# Create a PR to update a file
pr_url = my_supersonic.create_pr_from_content(
    repo="user/repo",
    content="print('hello world')",
    upstream_path="hello.py"
)

print(f"Created PR: {pr_url}")
```

### Working with Files and Content

Supersonic provides four main ways to create PRs, each designed for different use cases.
You can customize everything with keyword arguments, demonstrated below.

#### 1. Single File Updates (`create_pr_from_file`)

When you have a local file that you want to propose as a change:

```python
pr_url = my_supersonic.create_pr_from_file(
    repo="user/repo",
    local_file_path="local/config.json",  # Path to your local file
    upstream_path="config/settings.json",  # Where it should go in the repo
    title="Update configuration",  # Optional
    base_branch="develop"  # Optional, customize target branch
)
```

This is ideal for:
- Uploading configuration files
- Proposing documentation changes from local files
- Any single-file updates where you have the file locally

#### 2. Single Content Updates (`create_pr_from_content`)

When you have content in memory that you want to propose as a change:

```python
pr_url = my_supersonic.create_pr_from_content(
    repo="user/repo",
    content="print('hello')",  # The actual content
    upstream_path="src/hello.py",  # Where to put it in the repo
    title="Add hello script",  # Optional
    description="Adds a simple hello world script",  # Optional
    draft=False,  # Optional, create as draft PR
    labels=["enhancement"],  # Optional labels
    reviewers=["username"]  # Optional reviewers
)
```

This is perfect for:
- Generated content (e.g., from AI)
- Content manipulated in memory
- Simple text changes without needing a file

#### 3. Multiple Content Updates (`create_pr_from_multiple_contents`)

Use when you have multiple pieces of content in memory to update at once.
Now `contents` is a dictionary, with the key being the upstream file path,
and the value being the content. You can pass multiple keys, one for each 
file.

```python
pr_url = my_supersonic.create_pr_from_multiple_contents(
    repo="user/repo",
    contents={
        "config/settings.json": '{"debug": true}',
        "README.md": "# Updated Docs\n\nNew content here"
    },
    title="Update configuration and docs",  # Optional
    description="""
    This PR includes two changes:
    1. Updated debug settings
    2. Refreshed documentation
    """,  # Optional
    labels=["config", "docs"],  # Optional
    reviewers=["your-tech-lead", "somebody-else"]  # Optional
)
```

Great for:
- Batch updates to multiple files
- Generated content for multiple files
- Configuration changes across services
- Documentation updates across multiple files

#### 4. Multiple File Updates (`create_pr_from_files`)

Use if you have multiple local files to propose as changes.
You use `files` here, which is a dictionary mapping local file paths
to your desired upstream file paths.

```python
pr_url = my_supersonic.create_pr_from_files(
    repo="user/repo",
    files={
        "local/config.json": "config/settings.json",
        "local/README.md": "docs/README.md"
    },
    title="Update configs and docs",
    labels=["configuration", "documentation"]
)
```

Use for:
- Bulk file uploads
- Multi-file configuration changes
- Documentation updates from local files
- Any scenario where you have multiple local files to propose

### Common Options

All PR creation methods accept these common options:
- `title`: Custom PR title
- `description`: Detailed PR description
- `draft`: Create as draft PR (default: False)
- `labels`: List of labels to add, e.g. ["enhancement", "bugfix"]
- `reviewers`: List of GitHub usernames to request review from
- `base_branch`: Target branch (default: main)
- `auto_merge`: Enable auto-merge (default: False)
- `merge_strategy`: How to merge ("merge", "squash", "rebase")

## Pull Request Configuration

### Basic Usage

```python
# Configure PR options as keyword arguments
pr_url = my_supersonic.create_pr_from_content(
    repo="user/repo",
    content="print('hello')",
    upstream_path="src/hello.py",
    title="Add hello script",
    description="Adds a hello world script",
    base_branch="main",
    draft=False,
    labels=["enhancement"],
    reviewers=["username"]
)
```

### Using PRConfig with `create_pr`

For more control and reusability, use the `PRConfig` class 
directly with `create_pr`.

```python
from supersonic import PRConfig

config = PRConfig(
    title="Update configuration",  # Optional, defaults to "Automated changes"
    description="""
    This PR updates the configuration file with new settings.
    
    Changes:
    - Updated API endpoints
    - Added new feature flags
    """,  # Optional, supports markdown
    base_branch="main",
    draft=False,
    labels=["automated"],
    reviewers=["user1", "user2"],
    team_reviewers=["team1"],
    merge_strategy="squash",  # "merge", "squash", or "rebase"
    delete_branch_on_merge=True,
    auto_merge=False
)

my_supersonic = Supersonic("your-github-token")
pr_url = my_supersonic.create_pr(
    repo="user/repo",
    changes={"config.json": new_config_content},
    config=config
)
```

### Enterprise Usage

```python
supersonic = Supersonic({
    "github_token": "your-token",
    "base_url": "https://github.your-company.com/api/v3",
    "app_name": "your-tool",
    "default_pr_config": {
        "base_branch": "main",
        "draft": False,
        "labels": ["automated"],
        "merge_strategy": "squash",
        "delete_branch_on_merge": True
    }
})
```

## Configuration

### Full Configuration Options

You can optionally use a configuration dictionary when creating a `Supersonic` instance.
Only the GitHub token is required, and there are many options.

```python
config = {
    # Required
    "github_token": "your-token",
    
    # Optional
    "base_url": "https://api.github.com",  # For GitHub Enterprise
    "app_name": "your-app-name",
    
    # Default PR Configuration
    "default_pr_config": {
        "title": "Automated Update",  # Optional
        "description": "Changes proposed by Supersonic",  # Optional
        "base_branch": "main",
        "draft": False,
        "labels": ["automated"],
        "reviewers": [],
        "team_reviewers": [],
        "auto_merge": False,
        "merge_strategy": "squash",
        "delete_branch_on_merge": True
    }
}

my_supersonic_with_config = Supersonic(config)
```

### Environment Variables

Supersonic looks for these environment variables:
- `GITHUB_TOKEN`: GitHub API token

## Use Cases

### AI-Powered Code Improvements

Perfect for AI applications that suggest code improvements. Supersonic makes it easy to turn AI suggestions into pull requests:

```python
def handle_improvement_request(repo: str, file_path: str, user_prompt: str):
    # Your AI logic to generate improvements
    improved_code = ai.improve_code(user_prompt)
    
    # Create PR with improvements
    my_supersonic = Supersonic(config)
    pr_url = my_supersonic.create_pr_from_content(
        repo=repo,
        content=improved_code,
        upstream_path=file_path,
        title=f"AI: {user_prompt[:50]}...",
        description="""
        AI-suggested improvements based on code analysis.
        Please review the changes carefully.
        """,
        draft=True,  # Let users review AI changes
        labels=["ai-improvement"],
        reviewers=["tech-lead"]
    )
    return pr_url
```

### Automated Documentation Updates

Keep documentation in sync with code changes:

```python
def update_api_docs(repo: str, api_changes: Dict[str, Any]):
    # Generate updated docs
    docs = {
        "docs/api/endpoints.md": generate_endpoint_docs(api_changes),
        "docs/api/types.md": generate_type_docs(api_changes),
        "README.md": update_quickstart(api_changes)
    }
    
    # Create PR with all doc updates
    my_supersonic = Supersonic(config)
    pr_url = my_supersonic.create_pr_from_files(
        repo=repo,
        files=docs,
        title="Update API documentation",
        description="""
        # API Documentation Updates
        
        Automatically generated documentation updates based on API changes.
        """,
        labels=["documentation"],
        reviewers=["docs-team"],
        team_reviewers=["api-team"]
    )
    return pr_url
```

### Configuration Management

Manage customer configurations through PRs:

```python
def update_customer_config(customer_id: str, new_settings: Dict):
    repo = f"customers/{customer_id}/config"
    config_json = json.dumps(new_settings, indent=2)
    
    my_supersonic = Supersonic(config)
    pr_url = my_supersonic.create_pr_from_content(
        repo=repo,
        content=config_json,
        upstream_path="settings.json",
        title="Update customer configuration",
        description=f"""
        Configuration updates for customer {customer_id}
        
        Changes:
        {format_changes(new_settings)}
        """,
        reviewers=[f"@{customer_id}-admin"],  # Auto-assign customer admin
        labels=["config-change"],
        auto_merge=True,  # Enable auto-merge if tests pass
        merge_strategy="squash"
    )
