Please export YargsInstance from deno.ts as well

I keep needing this type when implementing commands, as this is the type of the argument supplied to the command builder.

Also, it would be really helpful if the types in deno-types.ts were also exported from deno.ts as well.

What I am doing now:

import yargs from "yargs/deno.ts";
import { Arguments } from "yargs/deno-types.ts";
import { YargsInstance } from "yargs/build/lib/yargs-factory.js";

export const hello = {
  command: "hello",
  builder(yargs: YargsInstance) {
    return yargs.option("name", name)
  },
  async handler(args: Arguments) {
    await console.log(`Hello ${args.name}!`)
  },
}

await yargs()
  .scriptName("example")
  .command(hello)
  .strictCommands()
  .demandCommand(1)
  .parse(Deno.args);

Ideally, from a Deno users perspective the I think it would be nice if they all came out of a single import:

import { yargs, YargsInstance, Arguments } from "yargs/deno.ts";

In node, the TypeScript types are supplied by Definitely Typed and maintained separately. I don't know if you can make use of those from Deno.

I think deno just treats them as two separate modules. It natively imports typescript files so whatever is in that file is what it interprets.

Here is an example usage for reference:
