Overview

ProfileLoader manages validation profiles and loads appropriate validators

This class provides a registry of validation profiles, each configured for specific use cases. Profiles define which validator to use, loading mode, and severity thresholds.

Available profiles:

  • indexability: Fast validation for font discovery (BasicValidator)
  • usability: Basic usability for installation (FontBookValidator)
  • production: Comprehensive quality checks (OpenTypeValidator)
  • web: Web embedding and optimization (WebFontValidator)
  • spec_compliance: Full OpenType spec compliance (OpenTypeValidator)
  • default: Alias for production profile

Examples:

Loading a profile

validator = ProfileLoader.load(:production)
report = validator.validate(font)

Getting profile info

info = ProfileLoader.profile_info(:web)
puts info[:description]
