impr: Better metadata versioning by aleksanderkatan · Pull Request #2502 · software-mansion/TypeGPU

aleksanderkatan · 2026-05-15T10:17:18Z

I did some additional rewriting. Most importantly, updateMetadata is now removed, since it was only used for setting name, and there are now two new global maps nameMap, metadataMap in addition to globalThis.__TYPEGPU_META__.

nameMap holds all names given to typegpu resources (if globalThis.__TYPEGPU_AUTONAME__ is defined, so is nameMap).
globalThis.__TYPEGPU_META__ now only holds raw function metadata.
metadataMap holds normalized function metadata, without the name. Also, the function's entry in globalThis.__TYPEGPU_META__ is cleared after normalization.

Why?
We needed a new map to store normalized metadata, because it may be queried multiple times, and without a map it would be recalculated every time.

Wile creating this new map, I wanted to 'consume' the metadata as soon as setName happened (otherwise, we'd need to merge multiple normalized metadatas), but there were issues with externals referencing values not yet defined. To avoid spaghetti, I split this into nameMap and metadataMap.

This also gives a clearer mental model, since now metadata is equivalent with 'use gpu' functions (tgpu.const no longer has metadata with all fields except name missing, no more optional on every function metadata field).

Further work (another ticket): remove externalNames: string[] from typegpu, and a few versions later also from unplugin (it is completely unnecessary, or at least it seems so)

Pull request overview

This PR improves TypeGPU function metadata handling by introducing explicit metadata versioning (v1/v2) and a normalization layer, then updating core/runtime and tests to consume the normalized API.

Changes:

Replaced raw getMetaData access with getFunctionMetadata throughout relevant runtime code and tests.
Added normalizeMetadata (v1/v2) to standardize externals + AST metadata for WGSL generation.
Added a new meta.test.ts suite covering missing metadata and unrecognized metadata versions, plus externals parsing for v1/v2.

File	Description
packages/typegpu/tests/tgsl/wgslGenerator.test.ts	Updates tests to use `getFunctionMetadata` instead of `getMetaData`.
packages/typegpu/tests/tgsl/tseynit.test.ts	Updates AST extraction helper to use `getFunctionMetadata`.
packages/typegpu/tests/meta.test.ts	Adds coverage for metadata normalization/versioning and error readability.
packages/typegpu/src/tgsl/shellless.ts	Switches shellless metadata access to `getFunctionMetadata` and adjusts error context naming.
packages/typegpu/src/shared/normalizeMetadata.ts	Introduces v1/v2 raw metadata types and normalization (incl. v2 externals getter conversion).
packages/typegpu/src/shared/meta.ts	Refactors metadata/name storage and adds `getFunctionMetadata` normalization/caching.
packages/typegpu/src/core/function/fnCore.ts	Uses normalized `pluginData.externals` instead of legacy raw externals handling.
