TS8013

When it fires

Host control flow and the JavaScript runtime forms no shader has: await, yield, an async or generator function, try/catch/throw, for…in, var, a spread outside an object literal, and a template string. A new is a class rule, CLASS_MEMBER.

Example

"use typeshade"

@fragment
export function main(@location(0) uv: vec2): vec4 {
  try {
    return vec4(uv, 0., 1.)
  } catch (e) {
    return vec4(0., 0., 0., 1.)
  }
}

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"

@fragment
export function main(@location(0) uv: vec2): vec4 {
  return vec4(uv, 0., 1.)
}
