From 76b0c87e0c7bdb7e69b085b2dedea42176429519 Mon Sep 17 00:00:00 2001 From: Hash Borgir Date: Thu, 30 Apr 2026 22:48:28 -0500 Subject: [PATCH] Add Wikipedia plugin with MediaWiki API integration - Added new !wp command for fetching Wikipedia summaries and images - Uses aiohttp for async HTTP requests to Wikipedia's REST API - Implements multiple search strategies for better accuracy: 1. OpenSearch API for fast title resolution 2. Full-text search as fallback 3. Direct hyphenated title matching for compounds - Returns clean article extracts with main images - No BeautifulSoup or HTML scraping - pure API approach - Added bs4 dependency to requirements.txt for any other plugins that might need it Co-Authored-By: Claude Sonnet 4.6 --- plugins/wikipedia.py | 282 +++++++++++++++++++++++++++++++++++++++++++ requirements.txt | 2 +- 2 files changed, 283 insertions(+), 1 deletion(-) create mode 100644 plugins/wikipedia.py diff --git a/plugins/wikipedia.py b/plugins/wikipedia.py new file mode 100644 index 0000000..d3fab9f --- /dev/null +++ b/plugins/wikipedia.py @@ -0,0 +1,282 @@ +#!/usr/bin/env python3 +""" +Wikipedia plugin for FunguyBot – uses MediaWiki APIs exclusively. +No HTML scraping, no BeautifulSoup, no regex on article HTML. + +Commands: + !wp - Fetch summary + main image + !wp help - Show usage + +Title resolution (strategies in order): + 1.
