RSS to Bluesky - in Python

This is a proof-of-concept implementation for posting RSS/Atom content to Bluesky. Some hacking may be required.

Built with:

• arrow - Time handling for humans
• atproto - AT protocol implementation for Python. The API of the library is still unstable, but the version is pinned in requirements.txt
• feedparser - For feed parsing

Features:

• Deduplication: The script queries the target timeline and only posts RSS items that are more recent than the latest top-level post by the handle
• Filters: Easy to extend code to support filters on RSS contents for simple transformations and limiting cross-posts
• Minimal rich-text support (links): Rich text is represented in a typed hierarchy in the AT protocol. This script currently performs post-processing on filtered string content of the input feeds to support links as long as they stand as a single line in the text. This definitely needs some improvement
