Specify an encoding?

I love the idea behind this library!

How about implementing the Proxy like this:

const {spawnSync} = require('child_process');
module.exports = new Proxy(
  {},
  {
    get: (_, bin) => (...args) => {
      return spawnSync(bin, args, {encoding: 'utf-8'});
    },
  }
)

A benefit of specifying an encoding is that you don’t need this code anymore: Object.assign(new String(out.stdout), out)

Are you using {...this} so that users can change the options of spawnSync()? Then I’d prefer a solution that doesn’t mutate a global object – maybe:

function createShell(userOptions = {}) {
  const options = {encoding: 'utf-8', ...userOptions};
  return new Proxy(
    {},
    {
      get: (_, bin) => (...args) => {
        return spawnSync(bin, args, {encoding: 'utf-8'});
      },
    }
  );
}

const sh = createShell();
console.log(sh.ls('-la'));

feat: add proxy factory

const {git, npm} = require('tinysh')({ cwd: 'foo/packages/bar' })

git('add .')
git('commit -m "foo"')
git('push origin HEAD:refs/heads/master')

npm('publish')

instead of

const {git, npm} = require('tinysh')

git.call({cwd}, 'add .')
git.call({cwd}, commit -m "foo"')
git.call({cwd}, 'push origin HEAD:refs/heads/master')

npm.call({cwd}, 'publish')
