#!/usr/bin/env python3 # -*- coding: utf-8 -*- """ Script: import_markdown.py — Markdown → Qdrant (Notes, Chunks, Edges) Version: 3.1.1 Datum: 2025-09-09 Kurzbeschreibung ---------------- Liest Markdown-Dateien aus einem Vault ein und schreibt Notes, Chunks und Edges idempotent nach Qdrant. Change-Detection basiert standardmäßig auf dem **Body-Hash** (ENV: MINDNET_HASH_MODE). Persistiert zusätzlich den Volltext der Note unter ``payload.fulltext`` und speichert den Vault-Pfad relativ. Abwärtskompatibilität --------------------- - Keine harte Abhängigkeit mehr von nicht gelieferten Modulen (validate_note, embed, edges). * Embeddings: Nullvektor-Fallback (Dim aus ENV/Config). * Edges: werden aus Chunk-Payloads + Note-Refs lokal abgeleitet. - IDs, Collections, Upsert-Semantik unverändert. ENV / Qdrant ------------ - QDRANT_URL (oder QDRANT_HOST/QDRANT_PORT) - QDRANT_API_KEY (optional) - COLLECTION_PREFIX (Default: mindnet) - VECTOR_DIM (Default: 384) - MINDNET_HASH_MODE: "body" (Default) | "frontmatter" | "body+frontmatter" Aufruf ------ python3 -m scripts.import_markdown --vault ./vault python3 -m scripts.import_markdown --vault ./vault --apply python3 -m scripts.import_markdown --vault ./vault --apply --purge-before-upsert python3 -m scripts.import_markdown --vault ./vault --note-id 20250821-foo --apply python3 -m scripts.import_markdown --vault ./vault --apply --embed-note """ from __future__ import annotations import argparse import json import os import sys from typing import Dict, List, Optional, Tuple from dotenv import load_dotenv from qdrant_client.http import models as rest # Core/Projekt-Module (vorhanden) from app.core.parser import ( read_markdown, normalize_frontmatter, validate_required_frontmatter, extract_wikilinks, ) from app.core.note_payload import make_note_payload from app.core.chunker import assemble_chunks from app.core.chunk_payload import make_chunk_payloads from app.core.qdrant import QdrantConfig, get_client, ensure_collections from app.core.qdrant_points import ( points_for_chunks, points_for_note, points_for_edges, upsert_batch, ) # Optionale Module (wenn nicht vorhanden → Fallback) try: from app.core.embed import embed_texts, embed_one # type: ignore except Exception: embed_texts = None embed_one = None # ----------------------------------------------------------------------------- # Hilfsfunktionen # ----------------------------------------------------------------------------- def iter_md(root: str) -> List[str]: """Sammelt alle .md-Dateien unterhalb von root, filtert systemische Ordner.""" out: List[str] = [] for dirpath, _, filenames in os.walk(root): for fn in filenames: if not fn.lower().endswith(".md"): continue p = os.path.join(dirpath, fn) pn = p.replace("\\", "/") if any(ex in pn for ex in ["/.obsidian/", "/_backup_frontmatter/", "/_imported/"]): continue out.append(p) return sorted(out) def collections(prefix: str) -> Tuple[str, str, str]: return f"{prefix}_notes", f"{prefix}_chunks", f"{prefix}_edges" def fetch_existing_note_hash(client, prefix: str, note_id: str) -> Optional[str]: """Liest den bisherigen hash_fulltext aus der Notes-Collection (falls vorhanden).""" notes_col, _, _ = collections(prefix) f = rest.Filter(must=[rest.FieldCondition( key="note_id", match=rest.MatchValue(value=note_id), )]) points, _ = client.scroll( collection_name=notes_col, scroll_filter=f, with_payload=True, with_vectors=False, limit=1, ) if not points: return None pl = points[0].payload or {} return pl.get("hash_fulltext") def purge_note_artifacts(client, prefix: str, note_id: str) -> None: """ Löscht alle Chunks+Edges zu einer Note.
