methods

new Markov(minimumWords, caseSensitive, stripPunctuation)

Create a new markov object. Optionally set minimumWords (default 1), caseSensitive (default false), stripPunctuation (default false).

.train(text)

Train the markov object with a string text, ignoring text with fewer than minimumWords words.

.search(text)

Search for and return some key found in the text body text.

Return undefined if no matches were found.

.pickWord(nodes, words)

Choose a word at random from nodes, optionally favoring words in words.

.next(key)

Find a key likely to follow after key.

Returns a hash with keys key, the canonical next key and word, a raw form of key as it appeared in the training text.

.prev(key)

Find a key likely to come before key.

Returns a hash with keys key, the canonical next key and word, a raw form of key as it appeared in the training text.

.fill(key, limit)

Generate a markov chain in both directions starting at key. Return an array of the raw word forms along the way including the raw word form of the supplied key.

Stop when the traversal hits a terminal entry or when limit words have been generated if limit is specified.

.respond(text, limit)

Search for a starting key in text and then call .fill(key, limit) on it.
