lightrag-cn-git/lightrag/parser/external/__init__.py

"""Adapters for external document parsing services.

Each subpackage under ``parser/external/`` integrates one external parser
(docling, mineru, ...) by handling:

- request/upload/poll choreography against the parser's HTTP API,
- on-disk caching of the raw bundle under ``<base>.<engine>_raw/``,
- normalization into LightRAG IR (``IRDoc``) for the sidecar writer.

Shared cross-engine helpers (size/hash, atomic manifest IO, safe zip
extraction, env coercion) live at this package root in private modules
prefixed ``_``. Engine-specific cache validation, manifest construction,
and IR adaptation live in each subpackage.
