No project description provided

kabigon

A URL content loader library that extracts content from various sources (YouTube, Instagram Reels, Twitter/X, Reddit, Truth Social, GitHub files, PDFs, web pages) and converts them to text/markdown format.

Features

✨ Multi-Platform Support: YouTube, Twitter/X, Truth Social, Reddit, Instagram Reels, PTT, GitHub files, PDFs, and generic web pages

🔄 Async-First Design: Built with async/await for efficient parallel processing

🎯 Smart Fallback: Automatically tries multiple extraction strategies until one succeeds

🚀 Simple API: Single-line usage with sensible defaults, or full control with custom loader chains

🔌 Extensible: Easy to add new loaders for additional platforms

Python API - Sync

import kabigon

url = "https://www.google.com.tw"

# Simplest usage - automatically uses the best loader
content = kabigon.load_url_sync(url)
print(content)

# Or use specific loader
content = kabigon.PlaywrightLoader().load_sync(url)
print(content)

# With multiple loaders (tries each in order)
loader = kabigon.Compose([
    kabigon.TwitterLoader(),
    kabigon.TruthSocialLoader(),
    kabigon.YoutubeLoader(),
    kabigon.RedditLoader(),
    kabigon.PDFLoader(),
    kabigon.PlaywrightLoader(),  # Fallback for generic URLs
])
content = loader.load_sync(url)
print(content)

Python API - Async

import asyncio
import kabigon

async def main():
    url = "https://www.google.com.tw"

    # Simplest usage - automatically uses the best loader
    content = await kabigon.load_url(url)
    print(content)

    # Or use specific loader
    loader = kabigon.PlaywrightLoader()
    content = await loader.load(url)
    print(content)

    # Batch processing multiple URLs in parallel
    urls = [
        "https://x.com/user1/status/123",
        "https://truthsocial.com/@user/posts/456",
        "https://youtube.com/watch?v=abc",
        "https://reddit.com/r/python/comments/xyz",
    ]

    loader = kabigon.Compose([
        kabigon.TwitterLoader(),
        kabigon.TruthSocialLoader(),
        kabigon.YoutubeLoader(),
        kabigon.RedditLoader(),
        kabigon.PlaywrightLoader(),
    ])

    # Parallel processing with automatic loader selection
    results = await asyncio.gather(*[kabigon.load_url(url) for url in urls])
    for url, content in zip(urls, results):
        print(f"{url}: {len(content)} chars")

asyncio.run(main())

Troubleshooting

Playwright browser not installed

Error: Executable doesn't exist at /path/to/chromium

Solution: Install Playwright browsers after installing kabigon:

playwright install chromium

FFmpeg not found (for audio transcription)

Error: ffmpeg not found

Solution: Install FFmpeg for your platform:

# Ubuntu/Debian
sudo apt-get install ffmpeg

# macOS
brew install ffmpeg

# Windows
# Download from https://ffmpeg.org/download.html

Or set custom FFmpeg path:

export FFMPEG_PATH=/path/to/ffmpeg

Timeout errors

Error: Timeout 30000ms exceeded

Solution: Increase timeout for slow-loading pages:

# Increase timeout to 60 seconds
loader = kabigon.PlaywrightLoader(timeout=60_000)
content = loader.load_sync(url)

CAPTCHA or rate limiting

Some websites may show CAPTCHAs or block automated access. For Reddit, kabigon automatically uses old.reddit.com to avoid CAPTCHAs. For other sites, you may need to:

• Add delays between requests
• Use a custom user agent
• Implement retry logic with exponential backoff

Contributing

Contributions are welcome! Please feel free to submit a Pull Request. For major changes, please open an issue first to discuss what you would like to change.

When adding a new loader:

1. Create a new file in src/kabigon/loaders/
2. Inherit from the Loader base class
3. Implement async def load(url: str) -> str
4. Add domain validation
5. Add tests in tests/loaders/
6. Update documentation

See CLAUDE.md for detailed development guidelines.
