nauyaca 0.4.0

Modern Gemini protocol server and client implementation using asyncio

Nauyaca - Gemini Protocol Server & Client

A modern, high-performance implementation of the Gemini protocol in Python. Nauyaca (pronounced "now-YAH-kah", meaning "serpent" in Nahuatl) uses asyncio's low-level Protocol/Transport pattern for efficient, non-blocking network I/O with both server and client capabilities.

Key Features

• High Performance - asyncio Protocol/Transport pattern for maximum efficiency
• Security First - Mandatory TLS 1.2+, TOFU certificate validation, rate limiting, and access control
• Production Ready - TOML configuration, middleware system, and systemd integration
• Developer Friendly - Full type hints, comprehensive tests, and modern tooling with uv

Quick Start

Installation

# As a CLI tool (recommended)
uv tool install nauyaca

# As a library
uv add nauyaca

# From source (for development)
git clone https://github.com/alanbato/nauyaca.git
cd nauyaca && uv sync

Run a Server

# Serve content from a directory
nauyaca serve ./capsule

# With configuration file
nauyaca serve --config config.toml

Fetch Content

# Get a Gemini resource
nauyaca get gemini://geminiprotocol.net/

# With verbose output
nauyaca get gemini://geminiprotocol.net/ --verbose

Use as a Library

import asyncio
from nauyaca.client import GeminiClient

async def main():
    async with GeminiClient() as client:
        response = await client.get("gemini://geminiprotocol.net/")

        if response.is_success():
            print(response.body)
        elif response.is_redirect():
            print(f"Redirect to: {response.redirect_url}")
        else:
            print(f"Error {response.status}: {response.meta}")

asyncio.run(main())
