This PR implements a complete link checking solution for the DC Helicopters repository to identify and categorize broken links across all markdown, HTML, and configuration files.
Tools Added
enhanced_link_checker.py) - Primary tool that scans all repository files and checks external links with intelligent categorization of network restrictions vs. truly broken linkstest_link_checker.py) - Validates link extraction and checking functionalityanalyze_broken_links.py) - Categorizes broken links by priority and type of issueKey Findings
After analyzing 290 total links across the repository:
Critical Issues Identified
http://github.com/cfpb/source-code-policy/in TERMS.md (line 46) - Returns forbidden statushttps://www.flickr.com/photos//20295326276/in/photostream/in index.md (line 36)Technical Approach
The link checker uses regex patterns to extract URLs from:
[text](url)<a href="url">It intelligently categorizes failures to distinguish between genuine broken links and network connectivity issues in restricted environments.
Usage
The tools are designed to be run in CI/CD pipelines for ongoing link maintenance and can provide more accurate results when run in unrestricted network environments.
Fixes #86.
