Add shortFlag option

[tunnckoCore]

Resolves #32

Let me know if that option name is okay, or if you don't want to have an option at all, which in turn will mean a major bump.

Example

const dargs = require('dargs');

const argv = require('minimist')(process.argv.slice(2));

console.log(dargs(argv, { allowSingleFlags: true }));
// => ['-a=123', '--foo=bar']

// Old behavior and still default one
console.log(dargs(argv));
// => ['--a=123', '--foo=bar']

I wouldn't use the word allow as it's not really about allowing it. It's more like transforming. And it's more commonly known as a short flag/option, so I think I would make the option just {shortFlag: true}.

You need to update https://github.com/sindresorhus/dargs/blob/master/index.d.ts too.

Cool, thanks. Yea, it wasn't sounding right to me too. I'll update it :)

So, am I understanding you correctly that you want it to be true by default? :)
If we set it to true by default, most of the tests are starting to fail and need edits, which would be a huge noise.

[sindresorhus]

No, not true by default.

[tunnckoCore]

Okay, let me know if something more is needed.

[sindresorhus]

Thanks :)
