This directory contains plugins that extend hexDAG's functionality.

Available Plugins

mysql_adapter	Production MySQL adapter with JSON support	database

Simple Plugin Workflow

Each plugin is a standalone Python package. Just use standard Python tools:

Install & Test

# Install a plugin
uv pip install -e hexdag_plugins/mysql_adapter/

# Run tests
uv run pytest hexdag_plugins/mysql_adapter/tests/

# Format code (uses settings from plugin's pyproject.toml)
cd hexdag_plugins/mysql_adapter
uv run ruff format .
uv run ruff check --fix .

Pre-commit Integration

Plugin files are automatically handled by the main pre-commit configuration. When you commit:

• Plugin files (hexdag_plugins/) use plugin-specific hooks with relaxed rules
• Main code (hexdag/) uses strict project hooks

This happens automatically - just commit normally and the right hooks run!

Plugin Structure

└── my_plugin/
    ├── pyproject.toml      # Plugin configuration & dependencies

    ├── my_plugin.py        # Implementation

        └── test_my_plugin.py

Creating a New Plugin

1. Copy an existing plugin directory as a template
2. Update pyproject.toml with your plugin details
3. Implement the required port interface
4. Write tests

The pyproject.toml contains all configuration:

• Dependencies
• Tool settings (ruff, mypy, pytest)
• Plugin metadata for hexDAG

Using Plugins

Plugins are used by referencing their full module path in YAML:

spec:
  ports:
    database:
      adapter: hexdag_plugins.mysql_adapter.MySQLAdapter

Or import directly in Python:

from hexdag_plugins.mysql_adapter import MySQLAdapter

adapter = MySQLAdapter(host="localhost", database="mydb")

That's it! No complex scripts or build tools needed.
