WIDL Code Generation
Deprecation Notice
The WIDL project has been extracted out of waPC and can now be found at github.com/apexlang
Description
This library works in tandem with wapc/widl-js to generate waPC
module code in Rust, AssemblyScript, and TinyGo.
Installation
$ npm install @wapc/widl
$ npm install @wapc/widl-codegen
Usage (node)
const widl = require("@wapc/widl");
const ast = require("@wapc/widl/ast");
const assemblyscript = require("@wapc/widl-codegen/assemblyscript");
const schema = `
namespace "mandelbrot"
interface {
update(width: u32, height: u32, limit: u32): [u16]
}`;
const context = new ast.Context({});
const doc = widl.parse(schema, { noLocation: true });
const writer = new ast.Writer();
const visitor = new assemblyscript.ScaffoldVisitor(writer);
doc.accept(context, visitor);
let source = writer.string();
console.log(source);
