Overview

FontExport represents complete font structure for export to YAML/JSON

This model encapsulates the entire font structure including header information, all tables (parsed and binary), and metadata. It supports round-trip conversion: font → export → import → font.

Examples:

Exporting a font

export = FontExport.new(source_file: "font.ttf")
export.extract_from_font(font)
yaml_output = export.to_yaml

Importing from YAML

export = FontExport.from_yaml(yaml_string)
font = export.rebuild_font
