Function: expand()

expand(text, defines): string

Defined in: src/gfx/graphics/webGpu/shader/util/PreprocessorExpr.ts:265

Single-pass identifier expansion.

Replaces each bare identifier in text with its defines value.

• arguments of defined(X) are preserved (so defined(FOO) never collapses to defined(1)).
• true / false / defined keywords are never substituted.
• unknown identifiers pass through unchanged.
• self-referential #define A A+1 does not loop — only the outer scan runs, the substituted A inside the RHS is not re-expanded.

Function-like macros are not supported; prefer fn in shader code.

Parameters

text

string

defines

Record<string, any>

Returns

string
