Automatic alias parsing about meow

[sindresorhus]

It's a cool idea. Not sure if it's a good fit here, though, as I'm trying to stay as unopinionated as possible. Gonna keep this open for a while to see if there's any interest in this.

In the meantime I made aliases (which uses parse-help), so you can easily plug it into meow.

const meow = require('meow');
const aliases = require('aliases');

const help = `
    Usage
      $ unicorn <name>

    Options
      -r, --rainbow  Lorem ipsum dolor sit amet
      -m, --magic    Aenean commodo ligula eget dolor
`;

meow(help, {
    alias: aliases(help, {h: 'help'})
})

You could potentially also make a more opinionated meow wrapper with this.

I like the idea, but rather don't want to see it implemented in meow directly. The solution of @sindresorhus is quite nice!

In my opinion, the implementation of the cli app is decoupled from the documentation of the app. Today, I choose for the -r, --rainbow notation. But maybe tomorrow I like --rainbow (-r) better. So if I change the documentation, my cli app breaks because I haven't thought about adding the alias property because my documentation format is not supported.

With the solution of @sindresorhus I can write my own parser for --rainbow (-r). And if I want -r, --rainbow back, I can use the aliases module.

@adjohnson916 I see what you're saying but I don't think the cli should impose aliases based on what our help text looks like.

Thanks @sindresorhus for creating aliases based on my idea. Modular magic is to me an acceptable alternative to meow magic. Perhaps at some point we could include it in meow as an opt-in feature. If not, we should at least link to it from the README here.
