Plugins

Using plugins

File-based plugins

Place the plugin file in either:

  • The main plugins directory of this module

  • A plugins directory in your profile

Use the /config files command to see a list of currently configured plugin paths.

Package-based plugins

Install the plugin package – see below for a list of package plugins.

Enabling plugins

Enable the plugin in your configuration:

plugins:
  enabled:
    # This is a list of plugins to enable, each list item
    # should be the name of a plugin file.
    # For file-based plugins, this is the filename without the
    # extension.
    # For package-based plugins, see the installation instructions
    # for the package.
    - test

Note that setting plugins.enabled will overwrite the default enabled plugins. Use the /plugins command for a list of currently enabled plugins.

Core plugins

These plugins are built into LWE core:

  • echo: Simple echo plugin, echos back the text you give it

  • examples: Easily install example configuration files (see Installing examples)

They can be disabled by removing them from plugins.enabled in your configuration file.

LWE maintained plugins

These plugins are maintained by the LWE team, and are not part of LWE core – they must be installed.

Instructions for installing and configuring each plugin can be found at the referenced repository for each plugin.

Shell command plugins

These plugins add additional commands to the shell:

Provider plugins

These plugins add additional LLM providers:

NOTE: Most provider plugins are NOT chat-based, and instead return a single response to any text input. These inputs and responses are still managed as ‘conversations’ for storage purposes, using the same storage mechanism the chat-based providers use.

Supported providers

NOTE: While these provider integrations are working, none have been well-tested yet.

Usage

Use the /providers command for a list of currently enabled providers.

See /help provider for how to switch providers/models on the fly.

Example:

/provider openai
/model model_name text-davinci-003

Writing plugins

There is currently no developer documentation for writing plugins.

The plugins directory has some default plugins, examining those will give a good idea for how to design a new one. In particular, the echo plugin is well commented. The package plugins listed above also contain many different approaches you can learn from.

To write new provider plugins, investigate the existing provider plugins as examples.

Currently, plugins for the shell can only add new commands.

Plugin structure

In order for plugins to load, a few simple conventions must be followed:

  1. All plugins must inherit from the base Plugin class, and provide implementations of the setup() and default_config() methods. Class name should be a camel-cased version of the plugin name:

    from lwe.core.plugin import Plugin
    
    class ExamplePlugin(Plugin):
        """
        An example plugin, does blah blah blah...
        """
    
        # Implement these...
        @abstractmethod
        def setup(self):
            pass
    
        @abstractmethod
        def default_config(self):
            pass
    

    The first line of the class docstring will be used as the plugin description.

  2. Naming conventions: Consider a plugin named example_plugin:
    • File-based plugin: The filename must be the plugin name with a .py extension, example_plugin.py

    • Package-based plugin: The the entry point must be lwe_plugins, and the plugin name must be prefixed with lwe-plugin-:

      setup(
          name="lwe-plugin-example-plugin",
          # Other setup options...
          entry_points={
               "lwe_plugins": [
                   "lwe_plugin_example_plugin = lwe_plugin_example_plugin.plugin:ExamplePlugin"
               ]
          },
      )
      

Available objects

An instantiated plugin has access to these objects.

  • self.config: The current instantiated Config object

  • self.log: The instantiated Logger object

  • self.backend: The instantiated backend

  • self.shell: The instantiated shell
