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.
