Sula: A Gemini protocol server written in Scryer Prolog
TL;DR
Sula is a Gemini protocol server built using a modified version of Scryer Prolog, enabling efficient streaming of binary file bodies to TLS clients. Key improvements include non-blocking I/O and lazy reading from process pipes.
✦ Why It Matters
Consider using Sula for your next project requiring efficient streaming of binary data over TLS.
Key Takeaways
- Install patched Scryer Prolog from the specified branch.
- Use command-line options to configure server settings.
- Implement error handling for TLS and connection issues.
- Plan for future features like client certificates and configuration files.
How It Works
Sula operates by utilizing a polyglot script that detects the Scryer Prolog environment and executes the server logic. It employs a native '$copy_stream'/2 method for efficient binary data streaming directly to TLS clients, minimizing memory usage.
The server also includes a non-blocking poll loop to handle incoming connections and interruptions gracefully, ensuring that the server remains responsive even during high load or unexpected client behavior.
