TS8050

When it fires

A file-level "enable <extension>"; directive (§50) naming an extension outside the vocabulary the WGSL backend's capability profile carries a directive for (clip_distances, dual_source_blending, f16, primitive_index, subgroups). A misspelled name would otherwise be an ordinary string expression statement and silently enable nothing.

Example

"use typeshade"
"enable f61";

declare const data: storage<array<f32>, "read_write">

@compute([64])
export function main(@builtin("global_invocation_id") id: vec3u): void {
  data[id.x] = data[id.x] * 2.
}

Compiled at build time against the pinned compiler, this program gets:

How to fix it

The same program, corrected. It compiles with no diagnostic.

"use typeshade"
"enable f16";

declare const data: storage<array<f32>, "read_write">

@compute([64])
export function main(@builtin("global_invocation_id") id: vec3u): void {
  data[id.x] = data[id.x] * 2.
}

The rule this enforces

Rule 10.1 Test

A "use typeshade" file must not spell a WGSL enable or requires statement.
