src/meta_tag_generator.py #!/usr/bin/env python3 """ Meta Tag Generator — SEO Toolkit by DataNest Generate comprehensive HTML meta tags, Open Graph tags, and Twitter Card tags from a simple JSON or YAML-like configuration. Outputs a ready-to-paste <head> block or a standalone HTML file. Why this exists: Manually writing meta tags is tedious and error-prone. Miss one og:image dimension and your social previews look broken. This tool generates all the tags you need from a single config, validates required fields, and warns you about common mistakes (missing descriptions, titles too long, etc.) before you deploy. Usage: python meta_tag_generator.py --config site.json python meta_tag_generator.py --config site.json --output head.html python meta_tag_generator.py --config site.json --format json License: MIT """ from __future__ import annotations import argparse import json import logging import sys import html from dataclasses import dataclass, field from pathlib import Path from typing import Any # --------------------------------------------------------------------------- # Constants # --------------------------------------------------------------------------- # Google typically displays 50-60 characters for titles TITLE_MAX_LENGTH = 60 TITLE_WARN_LENGTH = 50 # Meta descriptions should be 150-160 characters DESC_MAX_LENGTH = 160 DESC_WARN_LENGTH = 120 # Common charset values VALID_CHARSETS = {"utf-8", "iso-8859-1", "windows-1252", "ascii"} # Supported Open Graph types (subset of og:type values) # ... 467 more lines ...
