Quick example

import { vector } from 'mori';
import { assoc, equals } from 'mori-ext';

const v1 = vector('foo', 'bar', 'baz');
const v2 = v1::assoc(1, 'quux');
const v3 = vector('foo', 'quux', 'baz');
v2::equals(v3); // => true

How?

Using babeljs everyone can use this syntax.

Look at an example using gulp

Also, copy the .babelrc file, in order to enable the required language features in babeljs.

This effort is inspired by trine

Installation

npm install --save mori-ext

Usage

Review the spec (covers the majority of the API)

API

mori-ext's API is mostly based on collections being the first argument to mori functions, i.e.

import mori from 'mori';
import { equals, isList } from 'mori-ext';

const coll = mori.vector(1, 2, 3);

mori.isList(coll);
// is equivalent to
coll::isList();

// and

mori.equals(coll1, coll2);
// is equivalent to
coll1::equals(coll2);

However, not all functions operate on a single collection, or even, on collections at all, so some consideration has been taken into account, e.g.

import { list, vector, seq } from 'mori';
import { mapcat, cons } from 'mori-ext';
// mapcat
((x, y) => list(x, x + y))
  ::mapcat(seq('abc'), seq('123'));
// => ('a' 'a1' 'b' 'b2' 'c' 'c3')

// cons (converts collection into seq)
1::cons(vector(2, 3))
// => (1 2 3)
