`repack()`

Function in Emit

Emit manifest again from the portable IR it carries, with options: the same program, its WGSL, GLSL and layouts byte for byte what the build wrote, and the variants the build did not ask for.

import { repack } from 'typeshade/emit'

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

Syntax

function repack(manifest: Pack, options: { readonly console?: boolean } = {}): Pack

Parameters

manifest Pack
optionsoptional { readonly console?: boolean }

Return value

Pack

Exceptions

TypeError: TypeError when the manifest carries no IR, and when another package version wrote it, naming both versions: the IR is not a stable format, and only its own version reads it.

Description

The IR stays on the result, so it can be emitted again. options.console adds the recorded variant, the WGSL that records the console.* calls (surface §66).

The program is emitted under the options the manifest was packed under, the emit it records (packModule(m, { emit }), surface §69): its optimization level, its parens and its fp64Flavor, so its text and its bindings are the ones the build wrote and the variant it adds agrees with them. A manifest packed with emit plugins carries no IR (packModule refuses ir with a plugin: a plugin is a function, which a manifest cannot record).

Examples

Example

import { createRuntime } from 'typeshade/runtime';
import { repack } from 'typeshade/emit';

const rt = await createRuntime({ emit: repack });
const program = rt.load(manifest, { console: true }); // recorded, though the build did not
