# Foswig.js

[![Build Status](https://travis-ci.org/mrsharpoblunto/foswig.js.svg?branch=master)](https://travis-ci.org/mrsharpoblunto/foswig.js)

[![npm version](https://badge.fury.io/js/foswig.svg)](https://badge.fury.io/js/foswig)

A JavaScript library which allows you to easily create [Markov chains](http://en.wikipedia.org/wiki/Markov_chain) based on arbitrary dictionaries in order to create readable pseudo-random words (Yes, the name was generated by the library). See a demo of this library in action [here](http://mrsharpoblunto.github.io/foswig.js/).

## Usage

```javascript

// If you're using the following

// - A bundler like Rollup or Webpack

// - node>=12 and have set "type": "module" in your package.json

// - node>=12 and the parent file has a .mjs extension

import Foswig from 'foswig';

// otherwise require using commonjs

const Foswig = require('foswig').default;

// Create the Markov chain and specify the order of the chain & input dictionary

// The order (an integer that is greater than 0) indicates how many previous 

// letters are taken into account when selecting the next one. A smaller order 

// will result in a more randomized, less recognizeable output. Also, a higher 

// order will result in words which resemble more closely to those in the original 

//dictionary.

const chain = new Foswig(3, [

  "hello",

  "foswig",

]);

// Generate a random word with a minimum of 2 characters, a maximum of 10 letters, 

// and that cannot be a match to any of the input dictionaries words.

const constraints = { 

  minLength: 2, 

  maxLength: 10, 

  allowDuplicates: true

};

const word = chain.generate(constraints);

```

  

## Constraints

- *minLength* (optional, default: 0): Minimum length of the word

- *maxLength* (optional, default: 0): Maximum length of the word, 0 indicates no max length

- *allowDuplicates* (optional, default: true): Can the output be an exact match of a dictionary input word or not

- *maxAttempts* (optional, default: 25): The maximum number of attempts to generate a word matching the constraints above before throwing an error, use 0 to allow infinite attempts, but this may result in hangs if the constraints cannot be satisfied.

- *random* (optional, default: Math.random): A function that returns a random floating point number between 0-1.
