From d8de3b2ed7565b26a56fe193090a2c3881a467d2 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 28 Apr 2026 19:24:59 +0000 Subject: [PATCH 01/33] Add YouTube parser for comments and transcripts CLI tool that resolves search queries, channels, playlists, or video URLs to a list of videos, then fetches top-level comments (optionally with replies) via the YouTube Data API and transcripts via youtube-transcript-api. Writes per-video JSON + Markdown plus a summary CSV and index. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- requirements.txt | 2 + youtube_parser/__init__.py | 0 youtube_parser/comments.py | 104 +++++++++++++++++ youtube_parser/main.py | 174 +++++++++++++++++++++++++++ youtube_parser/output.py | 161 +++++++++++++++++++++++++ youtube_parser/sources.py | 214 ++++++++++++++++++++++++++++++++++ youtube_parser/transcripts.py | 68 +++++++++++ 7 files changed, 723 insertions(+) create mode 100644 requirements.txt create mode 100644 youtube_parser/__init__.py create mode 100644 youtube_parser/comments.py create mode 100644 youtube_parser/main.py create mode 100644 youtube_parser/output.py create mode 100644 youtube_parser/sources.py create mode 100644 youtube_parser/transcripts.py diff --git a/requirements.txt b/requirements.txt new file mode 100644 index 0000000..8c48264 --- /dev/null +++ b/requirements.txt @@ -0,0 +1,2 @@ +google-api-python-client>=2.100.0 +youtube-transcript-api>=0.6.2 diff --git a/youtube_parser/__init__.py b/youtube_parser/__init__.py new file mode 100644 index 0000000..e69de29 diff --git a/youtube_parser/comments.py b/youtube_parser/comments.py new file mode 100644 index 0000000..d4d6e35 --- /dev/null +++ b/youtube_parser/comments.py @@ -0,0 +1,104 @@ +"""Fetch comments (and optionally replies) for a video via YouTube Data API.""" +from __future__ import annotations + +from googleapiclient.discovery import Resource +from googleapiclient.errors import HttpError + + +def _format_comment(snippet: dict, comment_id: str, parent_id: str | None = None) -> dict: + return { + "comment_id": comment_id, + "parent_id": parent_id, + "author": snippet.get("authorDisplayName"), + "author_channel_id": (snippet.get("authorChannelId") or {}).get("value"), + "text": snippet.get("textOriginal") or snippet.get("textDisplay"), + "like_count": snippet.get("likeCount", 0), + "published_at": snippet.get("publishedAt"), + "updated_at": snippet.get("updatedAt"), + } + + +def fetch_comments( + youtube: Resource, + video_id: str, + *, + include_replies: bool = False, + max_comments: int | None = None, + order: str = "relevance", +) -> list[dict]: + """Fetch top-level comments.

The old code silently failed for every video because the broad except returned None on the AttributeError, so the UI always reported "no transcript". Rewrite transcripts.py against the new API and switch to a verbose return shape so callers can distinguish disabled, missing, and blocked cases.

Convenience aliases (--query, --channel, --video, --hashtag, --account, --post) and key=value setting overrides make scripted runs ergonomic. content_parser/ui/app.py renders the Streamlit interface from each plugin's input_specs() and settings_specs(), so adding a new source needs no UI changes. Sidebar manages secrets per plugin (load from st.secrets/env/config.json, save/clear buttons), the proxy block shows only when the active plugin has a proxy_provider setting. Root app.py is now a 3-line shim into content_parser.ui.app.main, so Streamlit Cloud picks up the new UI on next deploy. The legacy youtube_parser.main CLI keeps working unchanged via the back-compat shims introduced in the previous commit. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- app.py | 525 +--------------------------------- content_parser/cli.py | 145 ++++++++++ content_parser/ui/__init__.py | 0 content_parser/ui/app.py | 294 +++++++++++++++++++ 4 files changed, 442 insertions(+), 522 deletions(-) create mode 100644 content_parser/cli.py create mode 100644 content_parser/ui/__init__.py create mode 100644 content_parser/ui/app.py diff --git a/app.py b/app.py index f370fa0..ba3e84a 100644 --- a/app.py +++ b/app.py @@ -1,523 +1,4 @@ -"""Streamlit-интерфейс для YouTube-парсера.

The adapter maps Apify post fields (likesCount, videoViewCount, musicInfo, latestComments with nested replies) into the unified Item schema, with audio_id and audio_title surfaced under media for trend research. ApifyClient is a thin wrapper around run-sync-get-dataset-items with explicit handling of 401 (bad token) and 402 (out of credits). The plugin auto-registers via content_parser.core.registry, so the CLI and Streamlit UI pick it up without further changes — confirmed via 'python -m content_parser.cli list-sources'. Adds requests>=2.31.0 to requirements. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/plugins/instagram/__init__.py | 0 content_parser/plugins/instagram/adapter.py | 68 ++++++++++ .../plugins/instagram/apify_client.py | 54 ++++++++ content_parser/plugins/instagram/plugin.py | 123 ++++++++++++++++++ requirements.txt | 1 + 5 files changed, 246 insertions(+) create mode 100644 content_parser/plugins/instagram/__init__.py create mode 100644 content_parser/plugins/instagram/adapter.py create mode 100644 content_parser/plugins/instagram/apify_client.py create mode 100644 content_parser/plugins/instagram/plugin.py diff --git a/content_parser/plugins/instagram/__init__.py b/content_parser/plugins/instagram/__init__.py new file mode 100644 index 0000000..e69de29 diff --git a/content_parser/plugins/instagram/adapter.py b/content_parser/plugins/instagram/adapter.py new file mode 100644 index 0000000..31ba3e6 --- /dev/null +++ b/content_parser/plugins/instagram/adapter.py @@ -0,0 +1,68 @@ +"""Convert Apify Instagram-scraper output dicts into the unified core schema.""" +from __future__ import annotations + +from ...core.schema import Comment, Item + + +def _comment_from_apify(c: dict, parent_id: str | None = None) -> Comment: + return Comment( + comment_id=str(c.get("id") or c.get("comment_id") or ""), + parent_id=parent_id, + author=c.get("ownerUsername") or c.get("owner_username"), + author_id=str(c.get("ownerId") or c.get("owner_id") or "") or None, + text=c.get("text"), + like_count=int(c.get("likesCount", 0) or 0), + published_at=c.get("timestamp"), + ) + + +def _flatten_comments(raw: list[dict]) -> list[Comment]: + out: list[Comment] = [] + for c in raw or []: + top = _comment_from_apify(c) + out.append(top) + for reply in c.get("replies", []) or []: + out.append(_comment_from_apify(reply, parent_id=top.comment_id)) + return out + + +def post_to_item(post: dict) -> Item: + short_code = post.get("shortCode") or post.get("shortcode") or post.get("id", "") + url = post.get("url") or ( + f"https://www.instagram.com/p/{short_code}/" if short_code else "" + ) + + music = post.get("musicInfo") or {} + media: dict = { + "type": post.get("type"), # Image, Video, Sidecar + "view_count": post.get("videoViewCount") or post.get("videoPlayCount"), + "like_count": post.get("likesCount"), + "comment_count": post.get("commentsCount"), + "video_url": post.get("videoUrl"), + "display_url": post.get("displayUrl"), + "video_duration": post.get("videoDuration"), + "audio_id": music.get("audio_id") or music.get("audioId"), + "audio_artist": music.get("artist_name") or music.get("artistName"), + "audio_title": music.get("song_name") or music.get("songName"), + } + media = {k: v for k, v in media.items() if v is not None} + + return Item( + source="instagram", + item_id=short_code or post.get("id", ""), + url=url, + title=(post.get("caption") or "").split("\n", 1)[0][:120] or None, + author=post.get("ownerUsername") or post.get("owner_username"), + author_id=str(post.get("ownerId") or "") or None, + published_at=post.get("timestamp"), + text=post.get("caption"), + media=media, + comments=_flatten_comments(post.get("latestComments") or post.get("comments") or []), + extra={ + "hashtags": post.get("hashtags", []), + "mentions": post.get("mentions", []), + "location_name": post.get("locationName"), + "is_sponsored": post.get("isSponsored"), + "product_type": post.get("productType"), + }, + ) diff --git a/content_parser/plugins/instagram/apify_client.py b/content_parser/plugins/instagram/apify_client.py new file mode 100644 index 0000000..0b4ef3e --- /dev/null +++ b/content_parser/plugins/instagram/apify_client.py @@ -0,0 +1,54 @@ +"""Minimal Apify HTTP client — runs an actor synchronously and returns dataset items.""" +from __future__ import annotations + +from typing import Any + +import requests + + +APIFY_BASE = "https://api.apify.com/v2" + + +class ApifyError(Exception): + pass + + +class ApifyClient: + def __init__(self, token: str, timeout: int = 600): + if not token: + raise ValueError("Apify token is required") + self.token = token + self.timeout = timeout + + def run_actor( + self, + actor_id: str, + actor_input: dict[str, Any], + ) -> list[dict]: + """Run an actor synchronously and return its dataset items. + + actor_id: e.g. "apify/instagram-scraper" — slashes get replaced by '~'. + """ + slug = actor_id.replace("/", "~") + url = f"{APIFY_BASE}/acts/{slug}/run-sync-get-dataset-items" + params = {"token": self.token, "format": "json"} + try: + r = requests.post(url, params=params, json=actor_input, timeout=self.timeout) + except requests.RequestException as e: + raise ApifyError(f"Network error talking to Apify: {e}") from e + + if r.status_code == 401: + raise ApifyError("Apify rejected the token (401).

subreddit (name or URL, with or without 'r/' prefix) - query (full-text search across all of Reddit) - post_url (specific thread for comment analysis) - user (posts by a given Redditor — competitor tracking) Settings cover the listing knobs (hot/top/new/rising/controversial), time_filter for top/controversial, max posts per input, comment collection (top-level only by default, mirroring the YouTube plugin), and an opt-in expand_more_comments flag for users who want the full tree at the cost of slower scrapes. The adapter maps PRAW Submission/Comment objects into the unified Item schema: score / upvote_ratio / num_comments / NSFW + locked / spoiler flags / external link domain go into media; awards and post_hint go into extra. Deleted authors render as "[deleted]" rather than None. Comments are flattened with parent_id linkage so the same Markdown renderer that handles YouTube replies works unchanged. Secrets needed: REDDIT_CLIENT_ID + REDDIT_CLIENT_SECRET (free, created at reddit.com/prefs/apps as a "script" app). REDDIT_USER_AGENT is optional with a sensible default. Adds 41 new tests (75 total) covering adapter field mapping, input normalization (subreddit/user prefixes, URL parsing), reject paths (invalid chars, listing URL in post_url field), comment depth + cap behavior, and PRAW listing dispatch via mocks. praw>=7.7 added to requirements.txt. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/core/registry.py | 10 +-

669200a5d345989c8d01d1064c7649ac88b360b8 Mon Sep 17 00:00:00 2001 From: Claude <noreply@anthropic.com> Date: Wed, 29 Apr 2026 07:58:28 +0000 Subject: [PATCH 16/33] Address security review findings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - _file_stem now passes source and item_id through _safe_filename, not just title. Defense in depth against an upstream API returning a malicious id like '../../etc/passwd' that would have escaped the output directory. Verified by tests that hit write_item_json / write_item_markdown with traversal attempts and assert the resulting path stays under out_dir. - _is_reddit_post_url now matches host exactly (== 'reddit.com' or endswith '.reddit.com', same for redd.it). The previous substring check let 'evilreddit.com' and 'reddit.com.evil.example' through. Tests added for the lookalike rejection plus a positive case for legitimate subdomains like old.reddit.com. - build_reddit logs a WARNING when REDDIT_USER_AGENT is unset, before falling back to a generic default. Reddit's API rules ask for a username-bearing UA; the warning surfaces the misconfiguration that would otherwise just look like flaky rate limits. - Reddit fetch errors now go through _redact_spec, which strips query strings and caps length to 80 chars. Prevents accidentally pasting a URL with ?token=... into the field and seeing it echoed back through exception messages and Streamlit logs. - README.md adds a 'Sharing scraped results' section warning that comments are written to Markdown unescaped — fine for personal viewing, but raw output/ should not be republished without a sanitizer because of Markdown link injection vectors. - 19 new tests (94 total): _safe_filename behavior, _file_stem path traversal, write_item_* containment, _is_reddit_post_url lookalike rejection + subdomain acceptance, _redact_spec behavior, and build_reddit's logging assertion via patch.dict on sys.modules. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- README.md | 21 ++++- content_parser/core/output.py | 12 ++- content_parser/plugins/reddit/client.py | 15 +++- content_parser/plugins/reddit/plugin.py | 31 ++++++- tests/test_reddit_plugin.py | 77 +++++++++++++++++ tests/test_safe_filename.py | 107 ++++++++++++++++++++++++ 6 files changed, 256 insertions(+), 7 deletions(-) create mode 100644 tests/test_safe_filename.py diff --git a/README.md b/README.md index 588c2ae..bed686c 100644 --- a/README.md +++ b/README.md @@ -1,2 +1,21 @@ # claude -Репозиторий клода + +Парсер контента для ресёрча: YouTube, Instagram (через Apify), Reddit (через PRAW). +Streamlit-интерфейс + CLI; результаты в JSON / Markdown / CSV. + +## Sharing scraped results — security note + +Папка `output/` содержит **сырые комментарии** из публичных API.

Cosmetic — PRAW would still hit api.reddit.com — but keeps validation symmetric. Nice-to-haves while we're here: - replace_more on expand_more=True is now hard-capped at 32 expansions (constant _MAX_REPLACE_MORE) instead of unbounded. Unbounded calls could pull thousands of comments and minutes of latency on big threads. - 'rising' listing on a user (PRAW doesn't expose it) falls back to 'new' with an INFO log so the user sees why the result differs. - _is_reddit_host extracted as a shared helper used by all three URL validators. 8 new tests (102 total) cover stem collision avoidance, fragment redaction, whitespace UA fallback, non-reddit host rejection in both normalizers, replace_more cap, and the rising→new log. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/core/output.py | 33 +++++++++---- content_parser/plugins/reddit/client.py | 4 +- content_parser/plugins/reddit/plugin.py | 66 +++++++++++++++++-------- tests/test_reddit_plugin.py | 59 ++++++++++++++++++++-- tests/test_safe_filename.py | 23 +++++++++ 5 files changed, 149 insertions(+), 36 deletions(-) diff --git a/content_parser/core/output.py b/content_parser/core/output.py index 709c17d..b022a61 100644 --- a/content_parser/core/output.py +++ b/content_parser/core/output.py @@ -5,6 +5,7 @@ from __future__ import annotations import csv +import hashlib import json import re from dataclasses import asdict @@ -13,10 +14,13 @@ from .schema import Item +_FALLBACK_FILENAME = "item" + + def _safe_filename(name: str, max_length: int = 80) -> str: cleaned = re.sub(r"[^\w\s-]", "", name, flags=re.UNICODE).strip() cleaned = re.sub(r"\s+", "_", cleaned) - return cleaned[:max_length] or "item" + return cleaned[:max_length] or _FALLBACK_FILENAME def _format_seconds(seconds: float) -> str: @@ -27,17 +31,26 @@ def _format_seconds(seconds: float) -> str: def _file_stem(item: Item) -> str: - """Build a filesystem-safe stem. + """Build a filesystem-safe, collision-resistant stem. + + Every component goes through _safe_filename — defense in depth against an + upstream API returning a malicious id like '../../etc/passwd'. - Every component goes through _safe_filename, even though source and item_id - typically come from trusted internal strings — defense in depth against an - upstream API that returns a malicious id like '../../etc/passwd'. + If the item_id sanitizes away to the fallback (e.g. all special chars), a + short hash of the raw (source, item_id) is appended so two such items + don't clobber each other on disk.

From a1c85d1c87b9af167602cf2de8cd26a1f5047608 Mon Sep 17 00:00:00 2001 From: Claude <noreply@anthropic.com> Date: Wed, 29 Apr 2026 09:41:06 +0000 Subject: [PATCH 18/33] Add VK plugin: community search, walls, comments MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three input kinds: - query: groups.search → wall.get for each found community - community: screen_name / club<id> / numeric / vk.com URL - post_url: vk.com/wall<owner>_<post> Settings cover the whole pipeline: max communities per query, max posts per wall (capped at VK's 100/call), fetch_comments toggle, max comments per post (paginated via wall.getComments offsets), and comment_depth top_level vs all (with thread_items_count=10 when 'all'). The adapter resolves author names via the profiles + groups arrays returned by extended=1 calls — no extra users.get / groups.getById roundtrips. Negative owner_ids correctly map to club<id>; positive ones to id<id>. Security carry-overs from the previous reviews: - VKClient sends access_token in the POST body, never query string. - VK error_code 5/17/27/28 → AuthError; 6/9/29 → RateLimitError; rest → PluginError. UI surfaces these distinctly. - _normalize_community and _extract_wall_id reject non-VK hosts (vk.com, vk.ru, m.vk.com only — substring match would let evilvk.com through). - _normalize_community rejects VK reserved paths (feed, im, video, etc.) that would otherwise look like screen names but aren't communities. - _redact_spec strips ?query and #fragment before logging. 47 new tests (149 total): adapter field mapping for posts/comments and user vs group label resolution, normalization (screen_name / club / URL / lookalike host / reserved path), wall ID extraction, _redact_spec, client error code mapping, token-not-in-URL invariant, and fetch dispatch for query/community/post including dedupe across mixed inputs. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta ---

Also short-circuits pagination using the response's `count` field instead of doing one extra round-trip just to see an empty page. - VKClient retries RateLimitError (codes 6/9/29) with exponential backoff (1s, 2s, 4s, ... up to max_rate_limit_retries=3 by default) before bubbling up. AuthError and other PluginErrors are not retried. _sleep is a static method so tests can patch it without timing flakes. - VKClient now uses a single requests.Session for the whole client lifetime, so we don't pay the TLS handshake on every API call. - post_to_item raises ValueError when owner_id or id is missing, instead of silently constructing item_id="0_0" which would collide across multiple malformed posts. - _collect_for_spec post-path no longer duplicates the group/profile-cache lookup that the adapter already does via _label_for_id; just appends (post, None) and lets the adapter resolve. Extracted the shared response-merging logic into _extract_extended. 9 new tests (158 total): retry-then-succeed, give-up-after-max-retries, auth-not-retried, top-level cap exact, depth=all overflow control, single-page short-circuit on count, multi-page pagination continues when count > page, adapter ValueError on missing fields. The earlier ClientErrorMappingTest cases were updated to patch requests.Session (not requests.post) since the client now uses a session. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/plugins/vk/adapter.py | 8 +- content_parser/plugins/vk/client.py | 39 ++++- content_parser/plugins/vk/plugin.py | 79 ++++++---- tests/test_vk_plugin.py | 209 +++++++++++++++++++++++++-- 4 files changed, 283 insertions(+), 52 deletions(-) diff --git a/content_parser/plugins/vk/adapter.py b/content_parser/plugins/vk/adapter.py index ca78ad7..6ff4b0b 100644 --- a/content_parser/plugins/vk/adapter.py +++ b/content_parser/plugins/vk/adapter.py @@ -52,8 +52,12 @@ def post_to_item( profiles_by_id = profiles_by_id or {} groups_by_id = groups_by_id or {} - owner_id = int(post.get("owner_id", 0)) - post_id = int(post.get("id", 0)) + if post.get("owner_id") is None or post.get("id") is None: + raise ValueError( + f"Malformed VK post: missing owner_id or id (got keys {sorted(post.keys())[:8]})" + ) + owner_id = int(post["owner_id"]) + post_id = int(post["id"]) item_id = f"{owner_id}_{post_id}" if owner_label is None: diff --git a/content_parser/plugins/vk/client.py b/content_parser/plugins/vk/client.py index 200fa7a..780adca 100644 --- a/content_parser/plugins/vk/client.py +++ b/content_parser/plugins/vk/client.py @@ -5,6 +5,7 @@ """ from __future__ import annotations +import time from typing import Any import requests @@ -22,18 +23,48 @@ class VKClient: - def __init__(self, token: str, timeout: int = 60, version: str = VK_API_VERSION): + def __init__( + self, + token: str, + timeout: int = 60, + version: str = VK_API_VERSION, + max_rate_limit_retries: int = 3, + ): if not token: raise ValueError("VK access token is required") self.token = token self.timeout = timeout self.version = version + self.max_rate_limit_retries = max_rate_limit_retries + # Reuse one connection across requests to avoid TLS handshake per call. + self.session = requests.Session() + + @staticmethod + def _sleep(seconds: float) -> None: + time.sleep(seconds) def call(self, method: str, **params: Any) -> Any: - """Call a VK API method and return the unwrapped 'response' field. + """Call a VK API method with retries on rate-limit errors. - Raises AuthError, RateLimitError, or PluginError on VK-level errors. + Returns the unwrapped 'response' field.

channel: @username, plain username, or t.me URL (parses recent messages) - post_url: t.me/<channel>/<msg_id> for a specific post + its comments Reuses APIFY_API_TOKEN from the Instagram plugin so a Streamlit Cloud user only configures the Apify secret once. The default actor is apify/telegram-channel-scraper but actor_id is exposed as a setting so it can be swapped (e.g. 73code/telegram-scraper) without code edits. The adapter is field-shape-defensive because different Telegram scrapers on Apify use different key names: _pick walks a list of likely keys, _reactions_total accepts a list of {emoji, count} dicts, a flat {emoji: count} mapping, or just an int. Comments embedded in the message dict (replies_data, comments, discussion, thread.items) all parse to the same Comment list. Security carry-overs from the prior reviews: - _is_tg_host does exact-match on t.me / telegram.me to reject evilt.me and t.me.evil.example - _normalize_channel rejects Telegram reserved paths (joinchat, proxy, iv, etc.) that would otherwise look like usernames - _extract_post_url rejects /c/<chatid>/ private-channel paths since the public scrapers cannot read them - _redact_spec strips ?query and #fragment before logging - post-fetch comment count is capped to max_comments_per_post even when the actor returns more 49 new tests (207 total): _pick fallback chain, _reactions_total over all three reaction shapes, message_to_item with primary and alt field names, zero-views preserved, inline-comment extraction, alternative field-name fallbacks, host validation lookalike rejection, reserved path rejection, /c/ private path rejection, dispatch one-actor-call vs two for mixed inputs, actor_id override, dedupe across channel+post, and comment cap enforcement. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/core/registry.py | 5 + content_parser/plugins/telegram/__init__.py | 0 content_parser/plugins/telegram/adapter.py | 178 +++++++++++++ content_parser/plugins/telegram/plugin.py | 261 ++++++++++++++++++++ tests/test_telegram_adapter.py | 159 ++++++++++++ tests/test_telegram_plugin.py | 260 +++++++++++++++++++ 6 files changed, 863 insertions(+) create mode 100644 content_parser/plugins/telegram/__init__.py create mode 100644 content_parser/plugins/telegram/adapter.py create mode 100644 content_parser/plugins/telegram/plugin.py create mode 100644 tests/test_telegram_adapter.py create mode 100644 tests/test_telegram_plugin.py diff --git a/content_parser/core/registry.py b/content_parser/core/registry.py index e91d924..4e938c4 100644 --- a/content_parser/core/registry.py +++ b/content_parser/core/registry.py @@ -49,11 +49,16 @@ def _load_vk(): from ..plugins.vk.plugin import VKPlugin return VKPlugin() + def _load_telegram(): + from ..plugins.telegram.plugin import TelegramPlugin + return TelegramPlugin() + for loader, label in [ (_load_youtube, "youtube"), (_load_instagram, "instagram"), (_load_reddit, "reddit"), (_load_vk, "vk"), + (_load_telegram, "telegram"), ]: p = _try_load(loader, label) if p is not None: diff --git a/content_parser/plugins/telegram/__init__.py b/content_parser/plugins/telegram/__init__.py new file mode 100644 index 0000000..e69de29 diff --git a/content_parser/plugins/telegram/adapter.py b/content_parser/plugins/telegram/adapter.py new file mode 100644 index 0000000..076ffb0 --- /dev/null +++ b/content_parser/plugins/telegram/adapter.py @@ -0,0 +1,178 @@ +"""Convert Apify Telegram-scraper output dicts into the unified core schema. + +Field names vary between scraper actors, so the adapter looks up each +logical field through a list of likely keys (`_pick`) and falls back to None. +""" +from __future__ import annotations + +from datetime import datetime, timezone +from typing import Any + +from ...core.schema import Comment, Item + + +def _pick(d: dict, *keys: str, default: Any = None) -> Any: + for k in keys: + v = d.get(k) + if v not in (None, ""): + return v + return default + + +def _iso(value: Any) -> str | None: + """Accepts ISO string, UNIX timestamp, or None.""" + if value is None: + return None + if isinstance(value, str): + return value + try: + return datetime.fromtimestamp(float(value), tz=timezone.utc).isoformat() + except (TypeError, ValueError): + return None + + +def _reactions_total(reactions: Any) -> int | None: + """reactions can be: + [{"emoji": "👍", "count": 5}, ...] → sum counts + {"👍": 5, "❤️": 2} → sum values + an int → as-is + """ + if reactions is None: + return None + if isinstance(reactions, int): + return reactions + if isinstance(reactions, list): + total = 0 + for r in reactions: + if isinstance(r, dict): + try: + total += int(r.get("count", 0) or 0) + except (TypeError, ValueError): + continue + return total or None + if isinstance(reactions, dict): + try: + return sum(int(v or 0) for v in reactions.values()) + except (TypeError, ValueError): + return None + return None + + +def _channel_label(msg: dict) -> tuple[str | None, str | None]: + """Extract (display name, channel username) from a message dict.""" + title = _pick(msg, "channelTitle", "channel_title", "chatTitle", "chat_title") + username = _pick(msg, "channelUsername", "channel_username", "chatUsername", "chat_username") + if not title and not username: + #

Whitespace-only or unset falls back to the default actor cleanly; garbage like 'noslash' or '/missing' raises PluginError up-front instead of being sent to Apify and producing a confusing 404. - fetch() does ONE pass through actor results: parses each message to Item, dedupes by item_id in the same loop. The previous version parsed each message twice (once for dedupe key, once for yield) — doubles the adapter cost on big result sets. - _replies_count handles both shapes: 'replies: 42' (number) and 'replies: [...]' (list of comment dicts → use len). Previously number-only responses left media.comments_count as None. - _extract_comments now also looks at the bare 'replies' field for comment lists (not just replies_data/comments/discussion/thread). - Reply tree linkage: when a comment has reply_to_message_id (or replyToMessageId / reply_to_msg_id) and the parent is in the same fetched batch, we set parent_id accordingly so the Markdown writer can render the thread structure. Out-of-batch references stay top-level. - _is_private_channel_url helper catches t.me/c/<chat_id>/... before _extract_post_url returns None, raising an explicit PluginError that tells the user the URL is private and Apify scrapers can't read it. - _to_int defensively coerces numeric values, refusing to silently store a stray dict (e.g. {'count': 100}) in media when an actor uses an unexpected schema. Applied to views/forwards counts. - Cosmetic: media_obj computed once instead of msg.get('media') twice. 25 new tests (232 total): _to_int across all input shapes including the dict-leak guard, _replies_count for int/list/alt-keys, reply_to_message_id parent linkage with both inside and outside-batch references, dict-views does-not-leak, actor_id validation across five garbage forms plus default fallback for empty/whitespace, ApifyError → PluginError wrapping for both channels and posts paths, private /c/ URL explicit error. Also fixes a regression introduced in the previous edit pass where _channel_label lost its def line and became a continuation of _replies_count's body — caught by the test suite immediately. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/plugins/telegram/adapter.py | 66 ++++++++++--- content_parser/plugins/telegram/plugin.py | 53 ++++++---- tests/test_telegram_adapter.py | 97 ++++++++++++++++++ tests/test_telegram_plugin.py | 109 +++++++++++++++++++++ 4 files changed, 297 insertions(+), 28 deletions(-) diff --git a/content_parser/plugins/telegram/adapter.py b/content_parser/plugins/telegram/adapter.py index 076ffb0..321201c 100644 --- a/content_parser/plugins/telegram/adapter.py +++ b/content_parser/plugins/telegram/adapter.py @@ -58,6 +58,37 @@ def _reactions_total(reactions: Any) -> int | None: return None +def _to_int(value: Any) -> int | None: + """Coerce a numeric value to int.

Same loader code will be called from the cron runner in the next step, so it's designed for both interactive and headless use. Auth uses a Google Cloud service account: paste the JSON key into the GOOGLE_SHEETS_CREDENTIALS secret, then share each target spreadsheet with the service account's email (visible via .service_account_email() helper for UX hints). Loader API (content_parser/loaders/gsheets.py): loader = GoogleSheetsLoader.from_secrets({"GOOGLE_SHEETS_CREDENTIALS": ...}) loaded = loader.load(sheet_id_or_url, tab="Communities", range_a1="A:A", skip_header=False) loaded.values # ['durov_says', 'telegram', ...] — flattened, deduped, trimmed loaded.sheet_title / loaded.tab_title / loaded.count Sidebar block "📥 Загрузить из Google Sheets" exposes the same loader under any plugin: paste creds, paste sheet URL, pick tab + range, pick which input kind (channel / community / hashtag / etc.) to populate, hit Загрузить. Loaded values append to the existing input field (preserving manual entries), so several sheets can be merged before running. Defensive behavior: - credentials JSON is validated for type/client_email/private_key keys before sending to gspread, with a clear AuthError if it's e.g. an OAuth client JSON instead of a service account key. - Sheet URL extraction tolerates the ID alone, the full /d/<id>/edit URL, and trailing query params. - A1 range validated against a permissive regex; an actual range error from the API surfaces with the user's range echoed back. - 403 from Google → AuthError with "share the sheet" hint. 404 → PluginError with "check the URL/ID". - Unknown tab name → PluginError listing the tab names that DO exist. 20 new tests (252 total): credentials validation across all four malformed forms (non-JSON string, JSON-but-not-dict, missing field, missing secret), sheet ID extraction (bare ID / full URL / URL with query / garbage / empty), load() with single column / multi column / deduplication / blank-skipping / skip_header / invalid range / unknown tab / 403 / 404 / default-first-sheet. requirements.txt: +gspread>=6.0, +google-auth>=2.20 (the latter was already a transitive dep of google-api-python-client; pinning it explicitly makes the loader self-contained for cron use later). https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/loaders/__init__.py | 0 content_parser/loaders/gsheets.py | 216 +++++++++++++++++++++++++++++ content_parser/ui/app.py | 89 ++++++++++++ requirements.txt | 2 + tests/test_gsheets_loader.py | 207 +++++++++++++++++++++++++++ 5 files changed, 514 insertions(+) create mode 100644 content_parser/loaders/__init__.py create mode 100644 content_parser/loaders/gsheets.py create mode 100644 tests/test_gsheets_loader.py diff --git a/content_parser/loaders/__init__.py b/content_parser/loaders/__init__.py new file mode 100644 index 0000000..e69de29 diff --git a/content_parser/loaders/gsheets.py b/content_parser/loaders/gsheets.py new file mode 100644 index 0000000..462f5de --- /dev/null +++ b/content_parser/loaders/gsheets.py @@ -0,0 +1,216 @@ +"""Google Sheets loader: pull a column/range of values for plugin inputs. + +Auth: service-account JSON.

The previous regex.search would happily pull '/d/<id>/' out of any URL, including https://evil.com/.../d/<id>/... Not an SSRF (we don't fetch the user URL — the ID just becomes a parameter to the Google Sheets API), but the silent acceptance was misleading. Lookalike hosts and other google subdomains (mail.google.com etc.) are now rejected explicitly. - validate_credentials extracted as a static method that does the shape check WITHOUT building a gspread client. The save button now validates pasted JSON via this helper before persisting, so users see "JSON невалиден: …" immediately instead of saving garbage that fails on next load. - Service-account 'type' field is now checked too: an OAuth client JSON (type=authorized_user) is rejected with a message that points the user to the right kind of credential. - All UI buttons in this block translated to Russian (Сохранить / Удалить / ✏️ Заменить / ✕ Отмена) — was English-Russian mixed. Nice-to-haves while we're here: - After creds are saved, the field collapses to a one-line summary: "✓ Учётка сохранена: bot@project.iam.gserviceaccount.com" with a hint to share the spreadsheet with that email — addresses both the "where do I find this?" UX gap and the security concern of re-rendering the full RSA private key in plain text on every load. An ✏️ Заменить button reveals the textarea again. - A warning caption above the JSON field reminds the user that the JSON contains a private key. - st.spinner around the load call so the UI shows progress feedback. - Empty / whitespace 'tab' parameter falls back to the first sheet (matters for cron configs that may pass tab=""). - raw_rows dropped from LoadedRange — was populated but never read, carried unnecessary copies of full sheet data in memory. 8 new tests (260 total): non-google host rejected (with explicit docs.google.com hint in error), lookalike host rejected, other-google subdomain rejected (mail.google.com), OAuth client JSON rejected, validate_credentials does NOT call _build_client, empty/whitespace tab fallback to first sheet, raw_rows attribute removed from LoadedRange. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/loaders/gsheets.py | 56 ++++++++++++----- content_parser/ui/app.py | 101 ++++++++++++++++++++---------- tests/test_gsheets_loader.py | 66 +++++++++++++++++++ 3 files changed, 175 insertions(+), 48 deletions(-) diff --git a/content_parser/loaders/gsheets.py b/content_parser/loaders/gsheets.py index 462f5de..8b9654d 100644 --- a/content_parser/loaders/gsheets.py +++ b/content_parser/loaders/gsheets.py @@ -41,7 +41,6 @@ class LoadedRange: range_a1: str values: list[str] sheet_url: str - raw_rows: list[list[str]] = field(default_factory=list) @property def count(self) -> int: @@ -52,6 +51,16 @@ class GoogleSheetsLoader: """Thin wrapper around gspread for read-only sheet access.""" def __init__(self, credentials_json: dict | str): + self._credentials_json = self.validate_credentials(credentials_json) + self._gc = self._build_client() + + @staticmethod + def validate_credentials(credentials_json: dict | str) -> dict: + """Parse + shape-check service account JSON.

Job-files live in ~/.content_parser/jobs/<name>.yaml and are read with yaml.safe_load to keep the door closed on !!python/object construction tricks. Schema (jobs/schema.py): - Job dataclass with validate(): rejects bad names (regex ^[A-Za-z0-9_-]{1,64}$), missing source, invalid cron expressions, jobs without any inputs, malformed sheet_inputs, unknown notify_on_failure. - SheetInput dataclass mirrors GoogleSheetsLoader.load() args. - is_valid_cron loosely accepts standard 5-token expressions and @-aliases (@daily, @weekly, ...). It refuses garbage like 'rm -rf /' that contains characters outside [\d*/,-A-Za-z]. - resolved_output_dir() returns output/scheduled/<name>/<timestamp>/ by default, an absolute output_dir as-is, or a relative one resolved against cwd. The timestamp suffix is always appended. Store (jobs/store.py): - list_jobs() / load_job() / save_job() / delete_job() / job_exists(). - Path resolution validates the candidate is inside JOBS_DIR via Path.resolve() + relative_to() — defense in depth even though the job-name regex already keeps slashes out. - list_invalid() returns (name, error) pairs for files that fail to parse, so the UI can surface broken jobs instead of silently dropping. - save_job sets chmod 600 (best-effort). Runner (jobs/runner.py): - run_job(name) loads the YAML and runs run_job_obj(job). - _resolve_inputs merges inline values with Sheets-loaded values per input kind, then dedupes preserving insertion order, then drops empty kinds. - _collect_secrets pulls plugin secret_keys + GOOGLE_SHEETS_CREDENTIALS if any sheet_inputs present + the same WEBSHARE_/PROXY_ optional set the CLI/UI uses. - On success: writes .last_run.txt marker. On failure: writes last_error.txt with traceback unless notify_on_failure='none'. The original exception is re-raised so cron sees a non-zero exit. 48 new tests (308 total): cron expression validation across standard and alias forms (and rejection of cmd-injection-shaped garbage), Job validation across every guard (bad name / no source / no inputs / invalid schedule / malformed sheet ref / unknown notify), YAML round-trip + safe_load enforcement (rejects !!python/object), name_hint fallback when YAML omits 'name', range vs range_a1 alt key, resolved_output_dir for default/relative/absolute, store CRUD with path-traversal rejection, list_jobs sorting + skip-invalid behavior, chmod 600 on save, runner input merge with dedupe, secret collection (plugin / sheets-needed / optional proxy), success/failure marker writing, notify_on_failure=none suppresses error file, empty resolved inputs raise PluginError before plugin is touched. requirements.txt: +pyyaml>=6.0. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/jobs/__init__.py | 0 content_parser/jobs/runner.py | 151 +++++++++++++++++++++ content_parser/jobs/schema.py | 230 ++++++++++++++++++++++++++++++++ content_parser/jobs/store.py | 95 +++++++++++++ requirements.txt | 1 + tests/test_jobs_runner.py | 212 +++++++++++++++++++++++++++++ tests/test_jobs_schema.py | 214 +++++++++++++++++++++++++++++ tests/test_jobs_store.py | 84 ++++++++++++ 8 files changed, 987 insertions(+) create mode 100644 content_parser/jobs/__init__.py create mode 100644 content_parser/jobs/runner.py create mode 100644 content_parser/jobs/schema.py create mode 100644 content_parser/jobs/store.py create mode 100644 tests/test_jobs_runner.py create mode 100644 tests/test_jobs_schema.py create mode 100644 tests/test_jobs_store.py diff --git a/content_parser/jobs/__init__.py b/content_parser/jobs/__init__.py new file mode 100644 index 0000000..e69de29 diff --git a/content_parser/jobs/runner.py b/content_parser/jobs/runner.py new file mode 100644 index 0000000..81c19e6 --- /dev/null +++ b/content_parser/jobs/runner.py @@ -0,0 +1,151 @@ +"""Run a saved job: merge inline + Sheet inputs, call core.runner.run.""" +from __future__ import annotations + +import traceback +from datetime import datetime +from pathlib import Path +from typing import Callable + +from ..core.errors import PluginError +from ..core.registry import get_plugin +from ..core.runner import RunResult, run as core_run +from ..core.secrets import get_secret +from .schema import Job +from .store import load_job + + +# Optional secrets that any plugin may need but may not have been declared. +_OPTIONAL_SECRET_KEYS = ( + "WEBSHARE_USERNAME", + "WEBSHARE_PASSWORD", + "PROXY_HTTP_URL", + "PROXY_HTTPS_URL", + "GOOGLE_SHEETS_CREDENTIALS", +) + + +def _collect_secrets(plugin_secret_keys: list[str], *, need_sheets: bool) -> dict[str, str]: + """Gather every secret the job may need.""" + keys = list(plugin_secret_keys) + if need_sheets and "GOOGLE_SHEETS_CREDENTIALS" not in keys: + keys.append("GOOGLE_SHEETS_CREDENTIALS") + secrets: dict[str, str] = {k: get_secret(k) for k in keys} + for opt in _OPTIONAL_SECRET_KEYS: + v = get_secret(opt) + if v: + secrets[opt] = v + return secrets + + +def _resolve_inputs(job: Job, secrets: dict[str, str]) -> dict[str, list[str]]: + """Combine inline inputs with values pulled from any Google Sheets refs.""" + merged: dict[str, list[str]] = {k: list(v) for k, v in job.inputs.items()} + + if job.sheet_inputs: + from ..loaders.gsheets import GoogleSheetsLoader # noqa: PLC0415 + + loader = GoogleSheetsLoader.from_secrets(secrets) + for ref in job.sheet_inputs: + loaded = loader.load( + ref.sheet, + tab=ref.tab, + range_a1=ref.range_a1, + skip_header=ref.skip_header, + ) + merged.setdefault(ref.target, []).extend(loaded.values) + + # Per-kind dedupe preserving insertion order. + for kind, values in list(merged.items()): + merged[kind] = list(dict.fromkeys(values)) + # Drop empty kinds so plugins don't see them. + return {k: v for k, v in merged.items() if v} + + +def run_job( + name: str, + *, + log: Callable[[str], None] | None = None, + progress=None, +) -> RunResult: + """Resolve inputs and run a saved job.

install_cron(jobs=None, project_root=None, python_executable=None, log_path=None) — collects every job with a schedule, regenerates the managed block. Idempotent: running twice with the same jobs yields the same crontab. Existing user lines outside the markers are preserved. - remove_cron() — strips the block, returns True/False. - read_block() — best-effort parse of currently-installed entries (schedule, job_name, command). Safety: - shlex.quote on every path/argument that goes into the cron command, so even a hypothetical bad job name (which the schema regex already rejects) couldn't inject extra shell metacharacters. - Friendly errors for missing crontab binary and 'no crontab' state. CLI subcommand `jobs`: - jobs list → tabulated overview of all saved jobs + invalid files - jobs show <name> → dump a job's canonical YAML - jobs run <name> → invoke run_job() with stdout logging and progress - jobs install-cron → regenerate the managed block - jobs remove-cron → strip the managed block - jobs cron-status → show what's currently in the block 18 new tests (326 total): _strip_block leaves outside lines untouched and handles block-at-start, _build_block produces marker-wrapped lines with # job:<name> footer, build_command_for_job shell-quotes paths with spaces and uses safe paths as-is, install_cron idempotency across runs, jobs without schedule are skipped, lines outside markers preserved through reinstall, remove_cron only writes when block exists, read_block parses entries back, _existing_crontab returns "" for the "no crontab for user" case but raises on real errors and on missing binary. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/cli.py | 80 +++++++++++ content_parser/jobs/cron.py | 217 +++++++++++++++++++++++++++++ tests/test_jobs_cron.py | 264 ++++++++++++++++++++++++++++++++++++ 3 files changed, 561 insertions(+) create mode 100644 content_parser/jobs/cron.py create mode 100644 tests/test_jobs_cron.py diff --git a/content_parser/cli.py b/content_parser/cli.py index b56209e..1731a5b 100644 --- a/content_parser/cli.py +++ b/content_parser/cli.py @@ -16,6 +16,18 @@ def _build_parser() -> argparse.ArgumentParser: sub.add_parser("list-sources", help="Show registered source plugins") + # ----- jobs subcommand ----- + jobs_p = sub.add_parser("jobs", help="Manage scheduled jobs") + jobs_sub = jobs_p.add_subparsers(dest="jobs_command", required=True) + jobs_sub.add_parser("list", help="List all saved jobs") + show_p = jobs_sub.add_parser("show", help="Print a job's YAML") + show_p.add_argument("name") + run_job_p = jobs_sub.add_parser("run", help="Run a job once") + run_job_p.add_argument("name") + jobs_sub.add_parser("install-cron", help="Regenerate the managed crontab block") + jobs_sub.add_parser("remove-cron", help="Remove the managed crontab block") + jobs_sub.add_parser("cron-status", help="Show what's currently in the managed block") + run_p = sub.add_parser("run", help="Resolve inputs and fetch items for one source") run_p.add_argument("--source", required=True, help="Plugin name (e.g. youtube, instagram)") run_p.add_argument("--output", "-o", default=None, help="Output directory") @@ -132,12 +144,80 @@ def progress(done: int, total: int, message: str) -> None: return 0 +def cmd_jobs(args: argparse.Namespace) -> int: + from .jobs import store as jobs_store # noqa: PLC0415 + from .jobs.runner import run_job # noqa: PLC0415 + from .jobs.schema import dump_job_yaml # noqa: PLC0415 + + if args.jobs_command == "list": + jobs = jobs_store.list_jobs() + if not jobs: + print("No jobs found in", jobs_store.JOBS_DIR) + return 0 + for job in jobs: + schedule = job.schedule or "(manual)" + inputs_summary = ", ".join(f"{k}={len(v)}" for k, v in job.inputs.items()) or "—" + sheet_count = len(job.sheet_inputs) + print( + f"{job.name:30s} source={job.source:10s} schedule={schedule:20s} " + f"inline=[{inputs_summary}] sheet_refs={sheet_count}" + ) + invalid = jobs_store.list_invalid() + if invalid: + print() + print("Invalid job files:") + for name, err in invalid: + print(f" {name}: {err}") + return 0 + + if args.jobs_command == "show": + job = jobs_store.load_job(args.name) + print(dump_job_yaml(job)) + return 0 + + if args.jobs_command == "run": + result = run_job(args.name, log=print, progress=lambda d, t, m: print(f" [{d}/{t}] {m}")) + print(f"\nDone. {len(result.items)} item(s) saved to {result.out_dir.resolve()}") + return 0 + + if args.jobs_command == "install-cron": + from .jobs.cron import install_cron # noqa: PLC0415 + entries = install_cron() + if not entries: + print("No scheduled jobs found.

Lets the user: 1. List existing jobs with collapsed details: source, schedule (or "ручной запуск" badge), description, inline inputs and Sheet refs summary. 2. Per job: ▶️ Запустить (calls run_job_obj with live log), ✏️ Изменить (raw YAML editor with Save/Cancel), 🗑️ Удалить. 3. ➕ Создать job из текущего состояния — captures the current input tabs + plugin settings into a new YAML file. Bare-minimum form: name, optional cron, optional description; sheet_inputs added by editing the YAML afterward (since they need URL/tab/range fields). 4. 📅 Cron section, automatically grayed out on hosts without `crontab` binary (Streamlit Cloud) — there it shows a copy-paste GitHub Actions workflow as the alternative path. On hosts with crontab: install / remove buttons + summary of currently-installed entries. UI gracefully surfaces invalid YAML files via list_invalid() so a user who hand-edited a file and broke it can see the parse error instead of having the job silently disappear. is_cron_available() helper added to jobs/cron.py — runs a one-shot `crontab -l` and catches FileNotFoundError. UI calls it once per render to decide whether to show the install/remove buttons or the GH Actions template. Run button label updated to "▶️ Запустить (разово)" to disambiguate from the per-job ▶️ buttons in the Schedule panel. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/jobs/cron.py | 16 +++ content_parser/ui/app.py | 211 +++++++++++++++++++++++++++++++++++- 2 files changed, 226 insertions(+), 1 deletion(-) diff --git a/content_parser/jobs/cron.py b/content_parser/jobs/cron.py index defde37..bdeeb44 100644 --- a/content_parser/jobs/cron.py +++ b/content_parser/jobs/cron.py @@ -24,6 +24,22 @@ END_MARKER = "# <<< content_parser jobs <<<" +def is_cron_available() -> bool: + """Probe for a usable `crontab` binary.

The previous comprehension iterated strings character-by-character, so the typo 'community: durov_says' (no brackets) silently produced ['d','u','r',...]. Fix raises a clear PluginError before the typo can corrupt a run. - Job.validate() now rejects '..' anywhere in output_dir parts. Absolute paths still go through (user explicitly opts in), but the path-traversal case '../../etc' or 'custom/../escape' is caught at validation. - build_command_for_job rejects newlines and carriage returns in any path fragment (project_root, python_executable, log_path) and in job.name. shlex.quote happily preserves a literal \n inside its single-quoted output, which would split a crontab entry across two lines and corrupt the file. The schema's job-name regex already covers job.name, but the defense is added there too for future-proofing. - cli jobs run wraps run_job in try/except for AuthError, PluginError and KeyError (unknown source from get_plugin), printing a friendly stderr message and returning exit code 1 instead of dumping a Python traceback. - run_job_obj now computes resolved_output_dir() ONCE up-front. Earlier, a Sheets-load failure or empty-resolved-inputs would call job.resolved_output_dir() twice — once for the eventual run, again to pick a place for last_error.txt — producing two timestamped directories that differ by milliseconds. Now both markers land in the same dir. 12 new tests (338 total): output_dir rejected with .. at start / middle, absolute and normal-relative output_dirs accepted, string / int / dict values in inputs raise on YAML load (with the "must be a list" hint), empty input value treated as empty list, newline rejected in project_root / python_executable / log_path, carriage return rejected. The empty-resolved-inputs test in test_jobs_runner already verified the single-out_dir behavior end-to-end (passes with the refactor). https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/cli.py | 14 +++++++- content_parser/jobs/cron.py | 14 ++++++++ content_parser/jobs/runner.py | 23 +++++++----- content_parser/jobs/schema.py | 24 +++++++++++-- tests/test_jobs_cron.py | 41 ++++++++++++++++++++++ tests/test_jobs_schema.py | 66 +++++++++++++++++++++++++++++++++++ 6 files changed, 170 insertions(+), 12 deletions(-) diff --git a/content_parser/cli.py b/content_parser/cli.py index 1731a5b..a944161 100644 --- a/content_parser/cli.py +++ b/content_parser/cli.py @@ -176,7 +176,19 @@ def cmd_jobs(args: argparse.Namespace) -> int: return 0 if args.jobs_command == "run": - result = run_job(args.name, log=print, progress=lambda d, t, m: print(f" [{d}/{t}] {m}")) + from .core.errors import AuthError, PluginError # noqa: PLC0415 + try: + result = run_job( + args.name, log=print, + progress=lambda d, t, m: print(f" [{d}/{t}] {m}"), + ) + except (AuthError, PluginError) as e: + print(f"Error: {e}", file=sys.stderr) + return 1 + except KeyError as e: + # get_plugin raises KeyError for unknown source. + print(f"Error: unknown plugin/source — {e}", file=sys.stderr) + return 1 print(f"\nDone. {len(result.items)} item(s) saved to {result.out_dir.resolve()}") return 0 diff --git a/content_parser/jobs/cron.py b/content_parser/jobs/cron.py index bdeeb44..d06dd93 100644 --- a/content_parser/jobs/cron.py +++ b/content_parser/jobs/cron.py @@ -144,6 +144,20 @@ def build_command_for_job( python_executable = python_executable or sys.executable log_path = log_path or (project_root / "output" / "scheduled" / ".cron.log") + # crontab format is line-based, and shlex.quote happily preserves a + # newline inside its single-quoted output.

When the user enables 'transcribe_videos' in a plugin's settings, each Item with a video URL is downloaded as audio (MP3 64 kbps, well under the 25 MB Whisper API limit), shipped to api.openai.com/v1/audio/transcriptions, and the verbose_json segments are mapped onto the existing Transcript schema so the Markdown writer renders them the same way as YouTube subtitles. Module layout: - downloader.py — yt-dlp wrapper with FFmpegExtractAudio postprocessor and a 24 MB filesize cap. get_duration_seconds() probes without downloading for budget gating. - whisper_api.py — minimal Bearer-auth HTTP client (just `requests`, no `openai` package). Distinguishes 401 (bad key), 429 (rate limit), and other 4xx/5xx with the API's error message. - cache.py — ~/.content_parser/transcription_cache/<source>_<id>.json, so re-running a job doesn't re-pay for previously transcribed items. - runner.py — maybe_transcribe(item, settings, secrets, only_if_missing=) is the single entry point plugins call. Order: cache check → duration cap → download → API → cache write. Plugin integration: - Instagram, VK, Telegram add `transcribe_videos` (bool, default off) and `max_audio_seconds_per_video` (default 600) FieldSpecs and call maybe_transcribe inline in fetch(). - YouTube treats Whisper as a fallback: only_if_missing=True means it runs only when youtube-transcript-api couldn't return segments (subs disabled, blocked, etc.). Avoids wasting API on videos that already have free subtitles. UI: - Sidebar shows an inline 'Параметры Whisper' expander when transcribe_videos is checked, with OPENAI_API_KEY input + save/clear buttons + caption about the cost and ffmpeg requirement. - OPENAI_API_KEY is in the optional shared-secrets list, so a saved value is picked up across plugins and by the cron runner. Security carry-overs: - Token in Authorization: Bearer header, never URL. - _video_url_for prefers the canonical post URL (e.g. instagram.com/reel/AAA/) over CDN URLs in media.video_url, since CDN tokens often expire while yt-dlp can re-resolve from the post URL fresh. - Cache filenames go through _safe regex so a malicious upstream id like '../../etc' can't escape the cache dir. - Hard cap on audio duration before download blocks surprise costs. 24 new tests (362 total): cache CRUD with path-traversal sanitization; whisper_api Bearer header / verbose_json format / language passthrough / 401 / 429 / other-error message extraction / valid response parsing; maybe_transcribe disabled-by-setting / no-key-sets-error / cache-hit- skips-network / full-pipeline-downloads-and-caches / duration-cap-blocks / download-failure-recorded / whisper-failure-recorded / only_if_missing-skips-when-present / only_if_missing-runs-when-empty / no-video-url-silent / prefers-canonical-url-over-cdn. requirements.txt: +yt-dlp>=2024.0. ffmpeg required at runtime (documented in plugin help text). https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/jobs/runner.py | 1 + content_parser/plugins/instagram/plugin.py | 10 + content_parser/plugins/telegram/plugin.py | 8 + content_parser/plugins/vk/plugin.py | 8 + content_parser/plugins/youtube/plugin.py | 10 + content_parser/transcription/__init__.py | 0 content_parser/transcription/cache.py | 54 +++++ content_parser/transcription/downloader.py | 92 ++++++++ content_parser/transcription/runner.py | 146 +++++++++++++ content_parser/transcription/whisper_api.py | 74 +++++++ content_parser/ui/app.py | 33 ++- requirements.txt | 1 + tests/test_transcription_cache.py | 52 +++++ tests/test_transcription_runner.py | 222 ++++++++++++++++++++ tests/test_transcription_whisper.py | 100 +++++++++ 15 files changed, 810 insertions(+), 1 deletion(-) create mode 100644 content_parser/transcription/__init__.py create mode 100644 content_parser/transcription/cache.py create mode 100644 content_parser/transcription/downloader.py create mode 100644 content_parser/transcription/runner.py create mode 100644 content_parser/transcription/whisper_api.py create mode 100644 tests/test_transcription_cache.py create mode 100644 tests/test_transcription_runner.py create mode 100644 tests/test_transcription_whisper.py diff --git a/content_parser/jobs/runner.py b/content_parser/jobs/runner.py index dae7f34..5d1d459 100644 --- a/content_parser/jobs/runner.py +++ b/content_parser/jobs/runner.py @@ -21,6 +21,7 @@ "PROXY_HTTP_URL", "PROXY_HTTPS_URL", "GOOGLE_SHEETS_CREDENTIALS", + "OPENAI_API_KEY", ) diff --git a/content_parser/plugins/instagram/plugin.py b/content_parser/plugins/instagram/plugin.py index 1150be0..bab3061 100644 --- a/content_parser/plugins/instagram/plugin.py +++ b/content_parser/plugins/instagram/plugin.py @@ -55,6 +55,12 @@ def settings_specs(self) -> list[FieldSpec]: options=["posts", "details", "comments"], help="Для прямых ссылок на посты/рилсы всегда используется 'details'."), FieldSpec("add_parent_data", "Включать данные родительского аккаунта", "checkbox", False), + FieldSpec("transcribe_videos", "🎤 Транскрибировать видео (Whisper)", "checkbox", False, + help="Скачивает аудио рилса и шлёт в OpenAI Whisper.

29/33] Whisper review fixes: SSRF guard, unknown-duration block, retry, version pin MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Should-fix items: - runner.maybe_transcribe now refuses URLs that aren't public HTTP(S): loopback hostnames (localhost / 0.0.0.0), IPv4/IPv6 literals in private RFC1918 ranges, link-local (169.254.0.0/16 incl. AWS metadata), reserved and loopback. yt-dlp would otherwise happily fetch from internal networks if any third-party API (Apify/VK/Telegram actor) ever returned such a URL — chain-of-trust SSRF. Bare DNS names still pass since resolution happens later in yt-dlp; this layer only catches literals. - runner.maybe_transcribe blocks transcription when get_duration_seconds() returns None. Without a known length the per-video Whisper bill is unbounded; refusing is the cheap-and-safe default. Earlier code fell through this branch and would download anyway. - whisper_api.transcribe_audio retries 429 (rate limit) and 5xx (server error) up to max_retries=2 with exponential backoff (2s, 4s). 401/4xx other than those surface immediately. _sleep is a module-level helper so tests patch it without slowing the suite — TranscribeAudioTest's test_429_rate_limit was updated to use max_retries=0 for the no-retry semantic. Nice-to-haves: - yt-dlp pinned to >=2024.0,<2027.0 to bound supply-chain blast radius if a future major version ever ships a malicious extractor. - UI caption under Параметры Whisper now mentions that the saved key persists across checkbox toggles — only 🗑️ removes it. 17 new tests (379 total): _is_public_url across normal URLs, http variant, non-http schemes, localhost / 0.0.0.0 / 127.0.0.1 / IPv6 ::1, RFC1918 (10/172.16/192.168), link-local 169.254 (AWS metadata), IPv6 fc00::/7, empty/invalid input, DNS names pass through; runner blocks on private URL before any download; runner blocks on duration unknown; Whisper retry on 429-then-success / 500+503-then-success / exhausted retries; 401 and 400 do NOT retry (single call only). Existing test_429_rate_limit adjusted for new retry semantics. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/transcription/runner.py | 67 ++++++++++++++++- content_parser/transcription/whisper_api.py | 45 ++++++++++-- content_parser/ui/app.py | 4 +- requirements.txt | 2 +- tests/test_transcription_runner.py | 81 +++++++++++++++++++++ tests/test_transcription_whisper.py | 69 +++++++++++++++++- 6 files changed, 257 insertions(+), 11 deletions(-) diff --git a/content_parser/transcription/runner.py b/content_parser/transcription/runner.py index cb9c406..01a3a05 100644 --- a/content_parser/transcription/runner.py +++ b/content_parser/transcription/runner.py @@ -8,8 +8,10 @@ from __future__ import annotations import tempfile +from ipaddress import ip_address from pathlib import Path from typing import Any +from urllib.parse import urlparse from ..core.schema import Item, Transcript from . import cache as cache_mod @@ -17,6 +19,47 @@ from .whisper_api import WhisperError, transcribe_audio +# Hostnames that should never reach yt-dlp.

charset=UTF-8 Content-Transfer-Encoding: 8bit Three cross-cutting issues from the full-project review, in one batch: 1. GitHub Actions tests workflow (.github/workflows/tests.yml). Runs on every push and PR-to-main against Python 3.11 and 3.12, installs requirements.txt, runs `python -m unittest discover -s tests -v`, and smoke-checks `cli list-sources`. No more silent regressions between manual reviews. 2. _redact_spec was reimplemented in three plugins (Reddit, VK, Telegram), each with the security-relevant job of stripping ?query and #fragment from URLs before they hit logs or exception messages. When we added fragment-stripping to Reddit, the others were missed for a release. Extracted to content_parser/core/redact.py as redact_spec(). All three plugins now import the single canonical implementation; tests import from core.redact too (aliased to _redact_spec locally to keep diffs small). 3. ApifyClient lived in plugins/instagram/apify_client.py and Telegram imported from there — runtime cross-plugin dependency that would silently break if Instagram were renamed or removed. Moved to content_parser/clients/apify.py (a new top-level package for shared HTTP clients). Both Instagram and Telegram now import from the shared module; Instagram's old file is deleted. Tests adjusted to patch the new module path (content_parser.clients.apify.requests.post). All 379 tests still pass after the moves. https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- .github/workflows/tests.yml | 33 +++++++++++++++++++ content_parser/clients/__init__.py | 0 .../apify_client.py => clients/apify.py} | 7 +++- content_parser/core/redact.py | 29 ++++++++++++++++ content_parser/plugins/instagram/plugin.py | 2 +- content_parser/plugins/reddit/plugin.py | 18 ++-------- content_parser/plugins/telegram/plugin.py | 14 ++------ content_parser/plugins/vk/plugin.py | 14 ++------ tests/test_instagram_plugin.py | 4 +-- tests/test_reddit_plugin.py | 8 ++--- tests/test_telegram_plugin.py | 6 ++-- tests/test_vk_plugin.py | 3 +- 12 files changed, 86 insertions(+), 52 deletions(-) create mode 100644 .github/workflows/tests.yml create mode 100644 content_parser/clients/__init__.py rename content_parser/{plugins/instagram/apify_client.py => clients/apify.py} (87%) create mode 100644 content_parser/core/redact.py diff --git a/.github/workflows/tests.yml b/.github/workflows/tests.yml new file mode 100644 index 0000000..62b9add --- /dev/null +++ b/.github/workflows/tests.yml @@ -0,0 +1,33 @@ +name: tests + +on: + push: + pull_request: + branches: [main] + +jobs: + unittest: + runs-on: ubuntu-latest + strategy: + fail-fast: false + matrix: + python-version: ["3.11", "3.12"] + steps: + - uses: actions/checkout@v4 + + - name: Set up Python ${{ matrix.python-version }} + uses: actions/setup-python@v5 + with: + python-version: ${{ matrix.python-version }} + cache: pip + + - name: Install dependencies + run: | + python -m pip install --upgrade pip + pip install -r requirements.txt + + - name: Run unit tests + run: python -m unittest discover -s tests -v + + - name: Smoke-check CLI loads all plugins + run: python -m content_parser.cli list-sources diff --git a/content_parser/clients/__init__.py b/content_parser/clients/__init__.py new file mode 100644 index 0000000..e69de29 diff --git a/content_parser/plugins/instagram/apify_client.py b/content_parser/clients/apify.py similarity index 87% rename from content_parser/plugins/instagram/apify_client.py rename to content_parser/clients/apify.py index c95ef5f..598799f 100644 --- a/content_parser/plugins/instagram/apify_client.py +++ b/content_parser/clients/apify.py @@ -1,4 +1,9 @@ -"""Minimal Apify HTTP client — runs an actor synchronously and returns dataset items.""" +"""Minimal Apify HTTP client — runs an actor synchronously and returns dataset items. + +Lives outside the plugins/ tree so multiple plugins (Instagram, Telegram, …) +can share it without depending on each other.

Different tool for different jobs: - 'instagram' — публичные посты любого аккаунта (Apify, $$$) - 'instagram_graph' — твои посты + insights (Meta Graph API, бесплатно) What it gives that Apify can't: - Insights — reach, impressions, plays, saved, shares, total_interactions on your own Reels and posts - Full comment threads with replies and like counts - No per-item Apify cost - Stable, Meta-supported endpoint Files: - plugins/instagram_graph/client.py — GraphClient over graph.facebook.com with retry-on-429/5xx exponential backoff (2s, 4s), pagination via paging.next URL walking, embedded-token replacement so a 'next' URL can't smuggle a different token through, error-code mapping (190/102/etc → AuthError; 10/200/803 → AuthError "permissions"; 4/17/32/613 → RateLimitError). - plugins/instagram_graph/adapter.py — media_to_item maps a Graph media object (IMAGE/VIDEO/REEL/CAROUSEL_ALBUM) to core.Item with insights flattened into media dict; flatten_comments folds inline replies (replies.data) into the flat Comment list with parent_id. - plugins/instagram_graph/plugin.py — InstagramGraphPlugin with two inputs: 'account' (Business Account ID, 15-20 digits regex-validated) and 'post_id' (numeric media ID). Settings: max_posts_per_account, fetch_comments / fetch_replies / fetch_insights toggles, max_comments_per_post, plus the standard transcribe_videos / max_audio_seconds_per_video pair. Whisper integration via the same maybe_transcribe call as other video plugins. Plumbing: - registry.py registers the new plugin alongside the existing five. - jobs/runner.py adds INSTAGRAM_ACCESS_TOKEN to the optional secrets list, so cron jobs pick it up automatically. - ui/app.py shared-secrets list extended too. Auth requirements (documented in plugin.py docstring): Convert IG account to Business/Creator → connect to a FB Page → create Meta Developer App → generate long-lived token via Graph API Explorer with scopes instagram_basic, instagram_manage_comments, pages_show_list, business_management → store as INSTAGRAM_ACCESS_TOKEN. Insights are best-effort: if the /insights call returns a permissions error (common on archived posts or older media), we swallow it and continue with the rest of the run instead of dying. 42 new tests (421 total): client (token always overrides embedded ones, 401/code-10/code-4/5xx error mapping, retry-on-429-then-success, retry exhaustion, pagination across pages, max_items early-exit, embedded- token override on next URL); adapter (insights envelope flattening across dict/list shapes, media_to_item field mapping for REEL + non-REEL, owner_username override, missing-id raises, falls back gracefully when owner_username not passed, comment_to_core for top and reply, flatten_comments two-level expansion); plugin (resolve validates account-id length and post-id format, dedupe across inputs, fetch dispatch for account-path / post-path / mixed-with-dedupe, fetch_insights=False skips /insights endpoint entirely, insights failure does NOT abort the run). https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/core/registry.py | 5 + content_parser/jobs/runner.py | 1 + .../plugins/instagram_graph/__init__.py | 0 .../plugins/instagram_graph/adapter.py | 120 ++++++++ .../plugins/instagram_graph/client.py | 155 ++++++++++ .../plugins/instagram_graph/plugin.py | 267 ++++++++++++++++++ content_parser/ui/app.py | 2 +- tests/test_instagram_graph_adapter.py | 158 +++++++++++ tests/test_instagram_graph_client.py | 166 +++++++++++ tests/test_instagram_graph_plugin.py | 200 +++++++++++++ 10 files changed, 1073 insertions(+), 1 deletion(-) create mode 100644 content_parser/plugins/instagram_graph/__init__.py create mode 100644 content_parser/plugins/instagram_graph/adapter.py create mode 100644 content_parser/plugins/instagram_graph/client.py create mode 100644 content_parser/plugins/instagram_graph/plugin.py create mode 100644 tests/test_instagram_graph_adapter.py create mode 100644 tests/test_instagram_graph_client.py create mode 100644 tests/test_instagram_graph_plugin.py diff --git a/content_parser/core/registry.py b/content_parser/core/registry.py index 4e938c4..f907ca1 100644 --- a/content_parser/core/registry.py +++ b/content_parser/core/registry.py @@ -53,12 +53,17 @@ def _load_telegram(): from ..plugins.telegram.plugin import TelegramPlugin return TelegramPlugin() + def _load_instagram_graph(): + from ..plugins.instagram_graph.plugin import InstagramGraphPlugin + return InstagramGraphPlugin() + for loader, label in [ (_load_youtube, "youtube"), (_load_instagram, "instagram"), (_load_reddit, "reddit"), (_load_vk, "vk"), (_load_telegram, "telegram"), + (_load_instagram_graph, "instagram_graph"), ]: p = _try_load(loader, label) if p is not None: diff --git a/content_parser/jobs/runner.py b/content_parser/jobs/runner.py index 5d1d459..6a2294e 100644 --- a/content_parser/jobs/runner.py +++ b/content_parser/jobs/runner.py @@ -22,6 +22,7 @@ "PROXY_HTTPS_URL", "GOOGLE_SHEETS_CREDENTIALS", "OPENAI_API_KEY", + "INSTAGRAM_ACCESS_TOKEN", ) diff --git a/content_parser/plugins/instagram_graph/__init__.py b/content_parser/plugins/instagram_graph/__init__.py new file mode 100644 index 0000000..e69de29 diff --git a/content_parser/plugins/instagram_graph/adapter.py b/content_parser/plugins/instagram_graph/adapter.py new file mode 100644 index 0000000..99bd30d --- /dev/null +++ b/content_parser/plugins/instagram_graph/adapter.py @@ -0,0 +1,120 @@ +"""Convert Instagram Graph API responses into the unified core schema.""" +from __future__ import annotations + +from typing import Any + +from ...core.schema import Comment, Item + + +def media_to_item(media: dict, *, owner_username: str | None = None) -> Item: + """Convert a Graph API media object (post / reel / carousel) to core.Item. + + Comments are NOT populated here — the plugin attaches them after a + separate /{media-id}/comments call to keep paging explicit. + """ + if not media.get("id"): + raise ValueError( + f"Malformed Graph media: missing id (got keys {sorted(media.keys())[:6]})" + ) + + media_type = media.get("media_type") #

Claude <noreply@anthropic.com> Date: Wed, 29 Apr 2026 17:50:32 +0000 Subject: [PATCH 32/33] Instagram Graph review fixes: token redaction, precedence, no-mutation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Should-fix items: - GraphClient now scrubs the access token from any RequestException message before raising. The `requests` library sometimes embeds the full URL — including ?access_token=… — in connection-error messages, which would otherwise propagate to last_error.txt / Streamlit logs / CLI stderr. The exception is re-raised with `from None` so the chained __cause__ doesn't keep the unredacted original around either. - is_reel boolean now has explicit parens — (media_type == "REEL") or (media_type == "VIDEO" and product_type=="REELS") — instead of relying on Python's `and > or` precedence, which is easy to misread. - media_to_item accepts insights as a keyword argument instead of having callers mutate `media["insights"]`.

charset=UTF-8 Content-Transfer-Encoding: 8bit Six findings from the project-wide audit landed in one batch: 1. CSV formula injection guard (core/output.py). Excel/Sheets/LibreOffice execute any CSV cell starting with =, +, -, @, \t, \r as a formula (=cmd|'/c calc'!A1 is the canonical RCE proof-of-concept). User- controlled fields like title and author can come straight from Apify/Reddit/YouTube comments, which means any of our scrapes could ship a CSV that runs shell commands when a non-technical viewer opens it in Excel. _csv_safe prepends a single quote to neutralize the formula while keeping the value visible. Applied to every string column going into summary.csv. 2. Token redaction in last_error.txt (jobs/runner.py). The previous implementation wrote `traceback.format_exc()` raw — and tracebacks carry the chained exception's message, which can include API URLs with ?access_token=… in the query (we redact at the source for Instagram Graph but not in every other plugin's exception path). _record_failure now scrubs every secret value it knows about (8+ chars only, to skip noise) before the file lands on disk. Both call sites pass `secrets=secrets` from collect_secrets. 3. YouTube replies cap honored (plugins/youtube/comments.py). When include_replies=True, fetch_comments used to call _fetch_all_replies without bound — a single popular top-level comment with 500 replies would return 1+500 items only for `comments[:max_comments]` to throw most of them away. The fix threads `remaining = max_comments - len(comments)` through to _fetch_all_replies, which now stops both inside the inline loop and at page boundaries. Also requests page sizes proportional to remaining quota. 4. Atomic transcription cache (transcription/cache.py). put() now writes to <name>.json.tmp and renames over the final path. POSIX guarantees rename atomicity, so a crash during the write leaves either the old value or the new value, never a half-written JSON that get() catches as ValueError and silently treats as cache miss. 5. Streamlit Cloud detection in secrets layer (core/secrets.py). .streamlit/secrets.toml is managed by the Cloud dashboard and read-only at the filesystem level. Detect via STREAMLIT_RUNTIME env, STREAMLIT_SHARING, or HOSTNAME=streamlit-* and skip the file write entirely — local config.json (the other write target) still persists so the value works for the current container; users mirror it via Settings → Secrets for next deployment. 6. Unified .last_status.json (jobs/runner.py). Both _record_success and _record_failure now write a single canonical status file that monitoring / UI can stat once for "is this job healthy?". Schema: {job, source, status, finished_at, items, error}. Atomic write via .tmp+replace as well. 17 new tests (442 total): _csv_safe across all five injection-prone prefixes (= + - @ \t \r) and the safe-string / None / non-string passthrough cases; an end-to-end summary.csv test that injects a malicious title and verifies the round-tripped DictReader sees the quoted form. record_failure-redaction (passes a secret value, expects [REDACTED] in last_error.txt) and the new status-file shape. Cache atomicity (no .tmp left after success, second put() replaces first). Streamlit Cloud detection (STREAMLIT_RUNTIME=cloud → no file written; empty env → file written normally). https://claude.ai/code/session_01XhN8Fp3HF1K4PzwS3oofta --- content_parser/core/output.py | 32 ++++++++--- content_parser/core/secrets.py | 18 +++++++ content_parser/jobs/runner.py | 63 ++++++++++++++++++---- content_parser/plugins/youtube/comments.py | 28 ++++++++-- content_parser/transcription/cache.py | 10 +++- tests/test_jobs_runner.py | 39 ++++++++++++++ tests/test_safe_filename.py | 56 +++++++++++++++++++ tests/test_secrets.py | 16 ++++++ tests/test_transcription_cache.py | 12 +++++ 9 files changed, 251 insertions(+), 23 deletions(-) diff --git a/content_parser/core/output.py b/content_parser/core/output.py index b022a61..7d17f88 100644 --- a/content_parser/core/output.py +++ b/content_parser/core/output.py @@ -134,6 +134,22 @@ def write_item_markdown(item: Item, out_dir: Path) -> Path: return path +_CSV_INJECTION_PREFIXES = ("=", "+", "-", "@", "\t", "\r") + + +def _csv_safe(value): + """Defuse Excel-style formula injection in CSV cells. + + Excel/Sheets/LibreOffice treat any cell starting with =, +, -, @ as a + formula (incl. =cmd|'/c calc'!A1).
