Methods

.snip(string, options)

returns string

Snips the first part of the text with a min length. Returns only complete sentences or the entire input.

Options (defaults):

var _options = { 
  len: 100,                                   // min length of the snippet
  breakChars: [' ', '\n', '\r\n', '"', '<'],  // characters searched for after a stopChar is found
  stopChars: ['.', '!', '?']                  // characters used as sentence enders.
}

.chunk(string, options)

returns array of strings

Snips up an large string into smaller strings of snippets of complete sentences. Good for infinite scroll or paging applications.
