TS8022

Front-end code UNKNOWN_NAME

Reference to a name TypeShade cannot resolve (identifier, struct field, or struct shape) that is not a function call (UNKNOWN_FN) or a type name (UNKNOWN_TYPE), in a body a call lowers or in one no call lowers; a name the library declares for TypeScript's own use (Object, Math, Symbol), or the file declares as an enum, a namespace, a class or a type, read as a value says what it is.

The registry text and every compiler message on these pages are the compiler's own English.

Example

example.shade.ts
"use typeshade"


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

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

TS8022 error, line 5: Unknown identifier "gain".

How to fix it

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

example.shade.ts
"use typeshade"


const gain = 0.5


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

The rules this enforces

Rule 2.1 Test
Every author-facing name must come from exactly one of three sources:
Rule 2.2 Test
A compiler-internal name (§2.1) must not be authorable.
Rule 8.17 Test
A local function (a const that holds an arrow function or a function expression, or a function declaration, written inside a function’s body) is a function of the module named after the body that declares it (surface §14), and it may read and write the variables of the functions around it, as a TypeScript closure does.
Rule 12.4 Test
One mistake reads as one diagnostic; a refusal must not be followed by further diagnostics about the same mistake.

TS8002 UNKNOWN_TYPE
A type name nothing declares, said once for the file wherever it is written (a parameter, a claim, a type argument, B<vec3<Foo>> included, an alias, an implements clause, the base a class or an interface extends, a body no call lowers), a type the library declares for TypeScript alone (Number) where the file declares none of its name, or a type this surface does not take in a position the mapper reads (Rule 2.1).
TS8004 UNKNOWN_FN
A call to a function the file neither declares nor imports.
