PluginLoader

The PluginLoader dynamically loads and manages plugins from the mloda_plugins package.

Quick Start

from mloda.user import PluginLoader

# Load all plugins
loader = PluginLoader.all()

# Or load specific groups
loader = PluginLoader()
loader.load_group("feature_group")

Main Methods

PluginLoader.all()

Creates a loader and loads all available plugins.

load_group(group_name: str)

Loads all plugins from a specific group folder, including nested subdirectories. Supports slash-separated paths for subdirectories (e.g. "feature_group/input_data/read_files").

load_matching(group_name: str, pattern: str)

Loads only files within a group whose filename matches a glob pattern (e.g. "*transformer*"). Useful when only a subset of files in a group is needed.

load_all_plugins()

Loads all plugin groups.

disable_auto_load(group: str)

Prevents a group from being auto-loaded lazily. Call this before any plugin discovery if you want full control over what is loaded.

PluginLoader.disable_auto_load("feature_group/input_data/read_files")
PluginLoader.disable_auto_load("compute_framework")

list_loaded_modules(plugin_category: Optional[str])

Lists loaded plugin modules, optionally filtered by category.

display_plugin_graph(plugin_category: Optional[str])

Shows plugin dependencies as a graph.

Example

# Create loader and load plugins
loader = PluginLoader()
loader.load_all_plugins()

# List loaded modules
modules = loader.list_loaded_modules()

# Show dependencies
graph = loader.display_plugin_graph()

Plugins are automatically discovered from .py files in these directories.
