Legal Ass…

Truncates text. Prevents embarassing word splices. Truncation + business rules = FUNcation!

Installation

npm install legal-ass --save

Usage

LegalAss(phrase, options), where phrase is the string you'd like truncated and options is an object specifying the following:

Key	Value	Required?
length	(Integer) The maximum number of characters in the truncated return string, including any ellipses string that follows.	Yes
splitWords	(Boolean) Should the library truncate in the middle of a word? Defaults to false, meaning that the return string may be shorter than length if that's necessary to split between words.	No
ellipses	(String) A string to append to the end of the truncated text. Its length will be factored in to where a string truncates. Defaults to a single-character ellipses (…).	No

var LegalAss = require('legal-ass');

LegalAss('So this is a story all about how', {length: 22});
// -> 'So this is a story…'

Note that the returned string is only 19 characters long, since a longer string would have split in the middle of the word "all". If you don't care about this, pass {splitWords: true}:

LegalAss('So this is a story all about how', {length: 22, splitWords: true});
// -> 'So this is a story al…'

If you'd like to use your own string instead of ellipses, pass that as ellipses:

LegalAss('So this is a story all about how', {length: 22, ellipses: ' (More >)'});
// -> 'So this is a (More >)'

Note that the original phrase above was truncated with a trailing space and the library made the end result an additional character shorter by eliminating it.
