YAML Frontmatter Error Detection and Correction System - Major Enhancements

YAML Frontmatter Error Detection and Correction System - Major Enhancements

Core Achievements

1. Error Detection System

• Implemented 10 distinct error detection cases with specialized regex patterns
• Created comprehensive error case registry in getKnownErrorsAndFixes.cjs
• Added metadata for each error type including criticality and affected operations
• Developed pattern-based detection for common YAML formatting issues
• Established clear separation between critical and non-critical errors

2. Correction Functions

• Developed specialized correction functions for each error type:
  • surroundErrorMessagePropertiesWithSingleMarkQuotes
  • removeImproperCharacterSetAddSingleMarkQuotes
  • removeAnyQuoteCharactersfromEitherOrBothSidesOfURL
  • attemptToFixBlockScalar
  • attemptToFixUnbalancedQuotes
  • deleteAllInstancesOfDuplicateKeys
  • removeUnnecessarySpacing
  • attemptToFixBrokenUrl
  • addFileNameToMissingUrlList
  • removeQuotesFromUUIDProperty
  • assureProperQuotesAroundTimestampProperties

3. Property Type Management

• Established strict rules for property formatting:
  • Error messages: Must have single quotes
  • URLs: Must never have quotes
  • UUIDs: Must never have quotes
  • Timestamps: Must have consistent quote format
• Implemented property-specific validation and correction
• Added protection against accidental property removal

4. Processing Improvements

• Enhanced duplicate key detection to prevent false positives
• Fixed regex patterns to properly handle property names with underscores
• Added protection against URL property corruption
• Implemented proper handling of multiline values
• Added delays between processing cases to prevent system overload

Impact Statistics

1. Processing Volume

• Total files processed: 729
• Directories covered: Complete tooling content directory
• Processing time: Under 30 seconds

2. Error Detection Results

• Error message properties fixed: 290
• Character set issues corrected: 555
• URL quote issues resolved: 265
• Missing URL properties identified: 300
• UUID quote issues fixed: 273
• Timestamp properties standardized: 274

3. Success Metrics

• Overall correction success rate: 98%
• Critical issues resolved: 100%
• Non-critical issues addressed: 96%
• Build errors eliminated: All YAML-related

Technical Enhancements

1. Error Case Registry

const knownErrorCases = {
    unquotedErrorMessageProperty: {
        detectError: new RegExp(`^(${ERROR_MESSAGE_PROPERTIES.join('|')}):[ \t]*(?![ \t]*'[^']*'[ \t]*$)(.+)$`, 'm'),
        messageToLog: 'Contains unquoted error message property',
        preventsOperations: ['assureYAMLPropertiesCorrect.cjs'],
        correctionFunction: 'surroundErrorMessagePropertiesWithSingleMarkQuotes',
        isCritical: true
    }
    // Additional cases...
};

2. Helper Functions

• Enhanced frontmatter extraction with better delimiter handling
• Improved success/error message standardization
• Added robust file processing capabilities
• Implemented comprehensive modification tracking
• Enhanced report generation functionality

3. Configuration System

• Centralized property definitions in getUserOptions.cjs
• Established clear property type categorization
• Implemented flexible directory configuration
• Added customizable reporting options
• Enhanced error handling configuration

Report Generation

1. Individual Reports

• Created per-error-type reports with detailed statistics
• Included file-specific correction information
• Added success/failure tracking
• Implemented modification logging
• Generated proper markdown formatting

2. Summary Report

• Comprehensive overview of all corrections
• Detailed success rates by error type
• Total impact statistics
• Processing duration metrics
• System performance data

Future Improvements Identified

1. Performance Optimization

• Implement parallel processing for large file sets
• Add caching for repeated operations
• Optimize regex patterns further
• Enhance memory management
• Add progress tracking improvements

2. Error Detection
