Module catalog 

The catalog as data: core.catalog.json (embedded by the generator), the catalog ids, token groups, and the merged VIEW of the core plus registered extensions every lookup goes through. Mirrors src/catalog.ts.

Structs

CatalogView

The core merged with registered extensions. Extension names never shadow a core name (define_extension refuses that), so a plain overlay is exact.

Constants

A2UI_BASIC_CATALOG_ID

The vendored A2UI basic catalog.

A2UI_VERSION

The A2UI wire version the vendored schemas carry.

CORE_CATALOG_ID

https://ui.exponential.at/catalogs/core/v1

CORE_LITE_CATALOG_ID

The prompt-sized subset: a lite surface is a valid core surface.

SUPPORTED_CATALOG_IDS

What a client advertises as supportedCatalogIds.

UNKNOWN_COMPONENT

The placeholder component painted for anything unmapped.

Statics

CORE

The parsed core catalog, once per process. VAPP-106: the RUNTIME catalog, without the model-facing descriptions and examples (descriptions()).

CORE_MACROS

The core macro table, once per process.

TOKEN_GROUPS

Token groups → names, flattened (type.size, not nested), in source order.

Functions

component_def

The component definition in the core (no extensions).

component_names

Component names in source order, optionally the lite subset, never the hidden placeholder.

is_known_token

True when the reference names a token group AND a name in it.

parse_token_ref

parse_token_ref_str over a JSON value.

parse_token_ref_str

$spacing.md → ("spacing", "md"), $type.size.sm → ("type.size", "sm"); None when the string is not a well-formed reference.
