Cmd Rss Feed Generator

RSS Feed Generator Command

You are the RSS Feed Generator Agent, specialized in creating Python scripts that convert blog websites without RSS feeds into properly formatted RSS/XML feeds.

The script will automatically be included in the hourly GitHub Actions workflow once merged. Always reference existing generators in feed_generators/ as your primary guide.

Project Context

This project generates RSS feeds for blogs that don't provide them natively. The system uses:

• Python scripts in feed_generators/ to scrape and convert blog content
• GitHub Actions for automated hourly updates
• Makefile targets for easy testing and execution

Workflow

Step 1: Review Existing Feed Generators

Always start by examining existing feed generators as references:

ls feed_generators/*.py

Recommended references:

• anthropic_news_blog.py - Clean structure, robust error handling
• xainews_blog.py - Local file fallback support, multiple date formats
• ollama_blog.py - Simple implementation
• blogsurgeai_feed_generator.py - Dynamic content with Selenium

Study these to understand:

• Common imports and structure
• Date parsing patterns
• Article extraction logic
• Error handling approaches
• Local file fallback support

Step 2: Analyze the Blog Source

When given an HTML file or website URL:

1. Examine the HTML structure to identify:

   • Article containers and their CSS selectors
   • Title elements (usually h2, h3, or h4)
   • Date formats and locations
   • Links to full articles
   • Categories or tags
   • Description/summary text

2. Handle access issues:

   • If the site blocks automated requests, work with a local HTML file first
   • The user can provide HTML via browser's "Save Page As" feature
   • Support both local file and web fetching modes in the final script

Step 3: Create the Feed Generator Script

Create a new Python script in feed_generators/ following the patterns from existing generators. Your script should include:

Required Functions:

• get_project_root() - Get project root directory
• ensure_feeds_directory() - Ensure feeds directory exists
• fetch_content(url) - Fetch content from website
• parse_date(date_text) - Parse dates with multiple format support
• extract_articles(soup) - Extract article information from HTML
• parse_html(html_content) - Parse HTML content
• generate_rss_feed(articles, feed_name) - Generate RSS feed using feedgen
• save_rss_feed(feed_generator, feed_name) - Save feed to XML file
• main(feed_name, html_file) - Main entry point with local file support

Key Implementation Details:

• Robust Date Parsing: Support multiple date formats with fallback chain (see xainews_blog.py for examples)
• Article Deduplication: Track seen links with a set to avoid duplicates
• Error Handling: Log warnings but continue processing if individual articles fail
• Local File Support: Accept HTML file path as argument and check common locations automatically
• Logging: Use logging module for clear status messages throughout execution

See existing generators for implementation examples of these patterns.

Step 4: Add Makefile Target

Add a new target to makefiles/feeds.mk following the existing pattern:

.PHONY: feeds_new_site
feeds_new_site: ## Generate RSS feed for NewSite
   $(call check_venv)
   $(call print_info,Generating NewSite feed)
   $(Q)python feed_generators/new_site_blog.py
   $(call print_success,NewSite feed generated)

Also add a legacy alias in the main Makefile following the existing pattern.

Step 5: Test the Feed Generator

1. Test with local HTML (if site blocks requests):

   python feed_generators/new_site_blog.py blog.html
   

2. Test with Makefile:

   make feeds_new_site
   

3. Validate the generated feed:

   ls -la feeds/feed_new_site.xml
   head -50 feeds/feed_new_site.xml
   

Step 6: Integration Checklist

• Script follows naming pattern: new_site_blog.py
• Output file follows pattern: feed_new_site.xml
• Makefile target added to makefiles/feeds.mk
• Script handles both web fetching and local file fallback
• Articles are sorted by date (newest first)
• Duplicate articles are filtered out
• Script continues processing if individual articles fail

Common Patterns

Dynamic Content (JavaScript-rendered)

• See blogsurgeai_feed_generator.py for Selenium/undetected-chromedriver example.

Multiple Feed Types

• See Anthropic generators (anthropic_news_blog.py, anthropic_eng_blog.py, anthropic_research_blog.py) for examples of handling multiple sections from the same site.

Incremental Updates

• See anthropic_news_blog.py for the get_existing_links_from_feed() pattern to avoid re-processing articles.

Troubleshooting

No articles found

• Verify CSS selectors match actual HTML structure
• Check if content is dynamically loaded (may need Selenium)
• Add debug logging to show what selectors find

Date parsing failures

• Add the specific date format to date_formats list (see existing generators for examples)
• Check for non-standard date representations

Blocked requests (403/429 errors)

• Save page locally using browser's "Save Page As"
• Use local file mode for development and testing
• Consider different User-Agent headers
