static-electricity v1.0.2-alpha

static-electricity

⚠️ This library only barely works. It should not be used for production code.

FP library with rich static-land support.

Features

• Useful general-purpose structures like linked lists and Maybe
• static-land modules for easy abstraction
  • Canon module and canon function for when you don't want to explicitly pass around modules
• Combinators like always and id

Installation

npm install static-electricity

Basic example

const {Just, Nothing, match} = require ("static-electricity");
const {map} = require ("static-electricity/static-land/Maybe");

const bacon = Just ("bacon");
const food = map (x => `${x} ice cream`) (food);

const wouldYouLikeSome = match ({
  Just: x => `Yeah, ${x} sounds tasty.`,
  Nothing: () => "No, that doesn't sound very filling."
});

wouldYouLikeSome (food); // "Yeah, bacon ice cream sounds tasty."
wouldYouLikeSome (Nothing); // "No, that doesn't sound very filling."

More examples

99 bottles of beer

// This example does not work yet - the library is still very much a work in progress.
const {templateWith, unfold} = require ("static-electricity");
const bottleCount = bottles => bottles === 0 ? "No more bottles" :
  bottles === 1 ? "One more bottle" :
  `${bottles} more bottles`

const nBottles = templateWith ([bottleCount]) (
  `$0 of beer on the wall,
$0 of beer;
Take one down, pass it around,
$0 of beer on the wall.`
);

console.log (Array (99).fill ().map ((_, i) => nBottles (i).reverse ().join ("\n"));
