The context object that holds all the information we need when uncompiling a font.

Fields

lookups: IndexMap<SmolStr, LookupBlock>

All the lookups we have uncompiled so far, keyed by their name.

lookup_map: HashMap<(String, u16), SmolStr>

A mapping from (“sub”|“pos”, lookup_list_index) to the name of the lookup block we created for it. This is used to generate the correct lookup names in contextual lookups.

language_systems: IndexMap<Tag, IndexSet<Tag>>

A mapping from script tags to the language system tags that are present in the font.

unnamed_anchors: IndexMap<SmolStr, Vec<Anchor>>

Anchors on a glyph which we haven’t worked out what they should be called. class -> glyphname -> anchor

anchors: IndexMap<SmolStr, IndexMap<SmolStr, Anchor>>

Anchors on a glyph which we have worked out what they should be called.

mark_classes: IndexMap<SmolStr, Vec<MarkClassDefinition>>

Mark classes, indexed by class name.

named_classes: IndexMap<SmolStr, GlyphClass>

Named glyph classes, indexed by class name.

features: IndexMap<SmolStr, Vec<LookupReferenceStatement>>

Features, indexed by feature name.
