shortnames: Add possibility to set classname characters

👋 Hey, it would be great if it was possible to set characters, used in shortnames generated classes. For example, I'd prefer them to be only lowercase.

Feature Use Case

namer: shortnames({ letters: [a...z, 0...9] })

// or

namer: shortnames({ case: 'lower' })

Feature Proposal

Add option to set letters used in classes or letter case.

From source code, alphabet package is used inside which already has methods to return only lowercase/uppercase letters.

Btw shortnames is located under packages/namer, wondering why 🤔

That's left over from before this was a monorepo, hasn't been important to rename it but wanted to give the package a more-descriptive name on NPM.

I think this would be really easy to add, based on looking at namer.js:

modular-css/packages/namer/namer.js

Line 19 in 8a9214e

module.exports = () => {

Would need to take an option like shortnames({ identifiers : [ ... ] }), and the default value should be the already-existing everything value from up above.

modular-css/packages/namer/namer.js

Line 4 in 8a9214e

const everything = [ ...letters, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 ];

Then it's a matter of using the identifiers param instead of everything whenever value(...) is called.

modular-css/packages/namer/namer.js

Line 42 in 8a9214e

const output = value(letters, id) + value(everything, selectors.get(selector));

I have a package that generates short strings in a given alphabet: darthmaim/short-string.

I even wrote a package specifically for modular-css: darthmaim/modular-css-short-namer, but this will always use the default alphabet.
