Overview

System-font discovery: list the available fonts, resolve a name to a file path, and locate the bundled default. Font files are opened and cached natively (see R2D_FontCacheGet in the C extension), keyed by path, size, and style — there are no Ruby-side Font instances.

  font_name = font_name.to_s.downcase
  # Match against the file's basename (as `all` computes names), not the
  # whole path — otherwise a directory component like 'fonts' matches.
  all_paths.find { |path| path.split('/').last.chomp('.ttf').downcase.include?(font_name) }
