Spinner not showing on using silent exec

[tiloio]

Environment

• OS: Windows
• Node Version: v18.18.0
• Package: @clack/prompts
• Package Version: v0.7.0

Describe the bug No spinner is shown.

To Reproduce Run code on a real environment, shell is not working in stackblitz.

import { intro, outro, spinner } from '@clack/prompts';
import shell from "shelljs";

intro(`No spinner on shell.exec`);

const s = spinner();
s.start('Running install');
const command = await shell.exec('npm install', { silent: true });
const message = command.code === 0 ? "Installtion successful" : "Installation failed";
s.stop(message, command.code);

outro(`done`);

Steps to reproduce the behavior:

• Install shelljs `npm install shelljs
• run the script above
• no spinner is shown, the shell has just a empty line....

Expected behavior A spinner is shown.

Nodes normal exec is also not workin...

import { intro, outro, spinner } from '@clack/prompts';
import { execSync } from "node:child_process";

intro(`No spinner on execSync`);

const s = spinner();
s.start('Running install');
const command = execSync('npm install', { stdio: null });
const message = command.code === 0 ? "Installtion successful" : "Installation failed";
s.stop(message, command.code);

outro(`done`);

In both cases, you are using sync functions, which wouldn’t work. It will work if you turn them into async using util.promisify

import { intro, outro, spinner } from '@clack/prompts';

import { promisify } from "node:util";
import shell from "shelljs";

const exec = promisify(shell.exec);
intro(`No spinner on shell.exec`);

const s = spinner();
s.start('Running install');
const command = await exec('pnpm install', { silent: true }).catch(() => ({code: 1}));
const message = command.code === 0 ? "Installtion successful" : "Installation failed";
s.stop(message, command.code);

outro(`done`);
