`emitConst()`

Function in Emit

Emit one ConstDecl as a WGSL const line, without the surrounding module.

import { emitConst } from 'typeshade'

The signature, the description and the examples come from the compiler's own source at commit 26de7be8.

Syntax

const emitConst: (c: ConstDecl) => string

Parameters

c ConstDecl

Return value

string

Description

Use it to compose a shader out of separately authored pieces: emit the constants once, keep the string, and concatenate it with the rest of the source. The line is identical to the one emitModule writes for the same declaration, so a piece emitted here and a module emitted there agree, which is what makes concatenation safe.

The declaration is written as given: the passes emitModule runs before writing a module do not run here, so pass a declaration that needs none of them. The caveat on emitFuncs applies equally.
