Metadata (meta.ipynb)

Metadata introspection for the NLTK text plugin used by cjm-ctl to generate the registration manifest.

Import

from cjm_text_plugin_nltk.meta import (
    get_plugin_metadata
)

Functions

def get_plugin_metadata() -> Dict[str, Any]:  # Plugin metadata for manifest generation
    """Return metadata required to register this plugin with the PluginManager."""
    # Fallback base path (current behavior for backward compatibility)
    base_path = os.path.dirname(os.path.dirname(sys.executable))
    
    # Use CJM config if available, else fallback to env-relative paths
    cjm_data_dir = os.environ.get("CJM_DATA_DIR")
    
    # Plugin data directory
    plugin_name = "cjm-text-plugin-nltk"

NLTK Plugin (plugin.ipynb)

Plugin implementation for NLTK-based text processing with character-level span tracking

Import
