#!/usr/bin/env python3 # -*- coding: utf-8 -*- """ Name: scripts/import_markdown.py Version: v2.2.2 (2025-09-05) Kurzbeschreibung: Importiert Obsidian-Markdown-Notes in Qdrant (Notes/Chunks/Edges). - Leitet Wikilink-Edges (references/backlink/references_at) direkt aus Volltext + echten Chunk-Texten ab. - Idempotenz: Ermittelt hash_fulltext; bei Änderung werden alte Chunks/Edges der Note entfernt (Replace-on-Change). - Unveränderte Noten werden übersprungen (schnell). - Purge für Edges robust gegen Client-/API-Unterschiede (Filter + Scroll-Delete Fallback). Aufruf (aus Projekt-Root, im venv): python3 -m scripts.import_markdown --vault ./vault [--apply] [--note-id NOTE_ID] [--embed-note] [--force-replace] Parameter: --vault Pfad zum Vault (z. B. ./vault) --apply Führt Upserts in Qdrant aus (ohne Flag = Dry-Run mit JSON-Summaries) --note-id Bearbeite nur eine konkrete Note-ID --embed-note Optional: Note-Vektor (Volltext) zusätzlich einbetten --force-replace Erzwingt Purge & Neuaufbau auch ohne Hash-Änderung (Debug) Umgebungsvariablen (optional): QDRANT_URL, QDRANT_API_KEY, COLLECTION_PREFIX, VECTOR_DIM (Default 384) Exitcodes: 0 = OK, 2 = keine Markdown-Dateien gefunden Hinweise: - Wikilink-Ableitung basiert auf app.core.derive_edges (Slug-/ID-Auflösung, unresolved-Status). :contentReference[oaicite:3]{index=3} - Für references_at werden echte Chunk-Texte übergeben (sonst würden sie fehlen). :contentReference[oaicite:4]{index=4} - Purge verwendet: * Chunks: payload.note_id == NOTE_ID * Edges : (source_id == NOTE_ID) OR (target_id == NOTE_ID) OR (source_id startswith NOTE_ID + "#") → Falls MatchText/Prefix nicht unterstützt: Scroll & Delete-by-IDs als Fallback. - Notes/Chunks/Edges bleiben kompatibel zu Validator & Backfill (UUIDv5, 1D-Edges). Changelog: v2.2.2: Entfernt minimum_should (Kompatibilität); Edge-Purge mit Scroll-Fallback für source_id-Prefix. v2.2.1: Bugfix Tippfehler (args.force_replace). v2.2.0: Hash-basierte Replace-on-Change-Logik; Purge pro Note; Skip unverändert. :contentReference[oaicite:6]{index=6} v2.1.1: Sicherstellung references_at durch Übergabe echter Chunk-Texte. :contentReference[oaicite:7]{index=7} v2.1.0: Vorab-Note-Index über Vault; direkte Edge-Ableitung. :contentReference[oaicite:8]{index=8} """ from __future__ import annotations import argparse, os, glob, json, sys, hashlib from typing import List, Dict, Optional from dotenv import load_dotenv from qdrant_client import QdrantClient from qdrant_client.http import models as rest from app.core.parser import read_markdown, normalize_frontmatter, validate_required_frontmatter from app.core.note_payload import make_note_payload from app.core.validate_note import validate_note_payload from app.core.chunker import assemble_chunks from app.core.chunk_payload import make_chunk_payloads from app.core.embed import embed_texts, embed_one from app.core.qdrant import QdrantConfig, ensure_collections, get_client from app.core.qdrant_points import points_for_chunks, points_for_note, points_for_edges, upsert_batch from app.core.derive_edges import build_note_index, derive_wikilink_edges #
