How to use the @webassemblyjs/wast-printer.print function in @webassemblyjs/wast-printer

const { print } = require("@webassemblyjs/wast-printer");
const { readFileSync } = require("fs");

const filename = process.argv[2];

if (typeof filename === "undefined") {
  throw new Error("Missing file");
}

const content = readFileSync(filename, "utf8");
const ast = parse(content);

denormalizeTypeReferences.transform(ast);
wastIdentifierToIndex.transform(ast);

console.log(print(ast));

export function codeFrameFromAst(ast, loc) {
  return codeFrameFromSource(print(ast), loc);
}
export function codeFrameFromSource(source, loc) {

export function codeFrameFromAst(ast: Program, loc: SourceLocation): string {
  return codeFrameFromSource(print(ast), loc);
}

#!/usr/bin/env node
const { readFileSync } = require("fs");
const { decode } = require("@webassemblyjs/wasm-parser");
const { print } = require("@webassemblyjs/wast-printer");

function toArrayBuffer(buf) {
  return buf.buffer.slice(buf.byteOffset, buf.byteOffset + buf.byteLength);
}

const filename = process.argv[2];

const buff = toArrayBuffer(readFileSync(filename, null));
const ast = decode(buff);

const wast = print(ast);

process.stdout.write(wast);
