Prerequisites:

• Python 3.8+
• pip

Install dependencies:

• Windows PowerShell
  • python -m venv .venv
  • ..venv\Scripts\Activate.ps1
  • pip install -r requirements.txt

Run the app:

• python app.py
• Open http://127.0.0.1:5000

Notes:

• The app sets a friendly User‑Agent per Wikimedia policy.
• Optional HTTP caching via requests-cache (24h) if available.
• The development server is configured with use_reloader=False to avoid a Windows issue where the parent process exits immediately.

• GET / — Home
• POST / — Submit year form
• GET /year/ar> — Year details
• GET /api/year/ar> — JSON for the year (summary + sections)
• GET /compare//t;int:y2> — Compare two years
• GET /random — Redirect to a random year
• GET /export/.json;.json — Download JSON
• GET /export/.csvt;.csv — Download CSV (columns: section,item)

• Data is fetched from Wikipedia using the MediaWiki API and the REST summary API.
• In‑memory caching via functools.lru_cache reduces repeat lookups.
• If requests-cache is installed, outbound HTTP calls are cached on disk for 24 hours.

• ← / → — Previous / Next year
• E — Expand all lists
• C — Collapse all lists
• / — Focus first filter
• T — Back to top
• Ctrl+K — Open command palette

• Blank page or no items: verify internet access and try another year (some pages may have sparse sections). Check console/network for Wikipedia errors.
• Stuck loading overlay: refresh; the overlay automatically hides on load and via a safety timeout.
• Windows: if the terminal shows the server starting but nothing stays running, ensure you are using python app.py (reloader is disabled in code).
