#Markov-strings

A simplistic Markov chain text generator.

Give it an array of strings, and it will output a randomly generated string.

##Getting started

###Prerequisites This module makes use of ES6 features.

###Installing npm install --save markov-strings

###Basic usage

let Markov = require('markov-strings');

let data = [];    // An array of strings
let options = {}; // An optional object of options
let generator = new Markov(data, options);

let refinedOptions = {}; // An optional object of options, for this particular generation
generator.generateSentence(refinedOptions);  // Outputs an object, containing a string and a score

###Options You can provide options during the generator instantiation, and/or while calling generateSentence().

The options object will alter the quality, length, etc. of the generated sentences.

Options given to generateSentence() overwrite those given during instantiation. It can be useful if you wish to generate multiple sentences with slight variations each time.

#####stateSize Type: integer
Default: 2

The number of words for each state.
1 will output gibberish sentences without much sense.
2 is a sensible default.
3 and more could create good sentences, at the expense of randomness. You'll need a good corpus, though.

#####maxLength Type: integer
Default: 0

Maximum characters.

#####minWords Type: integer
Default: 5

Minimum number of words.

#####maxWords Type: integer
Default: 0

Maximum number of words.

#####minScore Type: integer
Default: 0

Each generated sentence will be associated to a score. The highest this score, the more random the sentence should be.

A good minScore value totally depends of your corpus, and the number of words of the sentence, so you'll have to try yourself.
