Why doesn’t Mootools have a String.truncate() method?

[Michael Fuery]

I need a quick way to truncate strings! I’m surprised that neither
MooTools’ String.js or String.Extras.js has such a method. They have
so many super-awesome functions, methods and extensions (I especially
love the Date.js extensions!!). Yeah, I really love mootools, and I
feel compelled to share with the community. So anyway, I wrote out a
simple, straightforward String.truncate() function.

Comments, suggestions, corrections and extensions are always welcomed!

<pre lang="javascript" line="1">
String.implement({
/**
* String.truncate(max, atChar, trail)
*
* ++All parameters are optional.
* @param max = (integer) maximum length of truncated string.
Defaults to 100 chars.
* @param atChar = (string) truncate at the last index of this
string. If not found, just truncates to max length.
* If null, does not search and truncates to max
length.
* @param trail = (string) what you want appended to the end of
the returned string
*
* @author Michael Fuery, Fuery Solutions, Inc. http://www.fuerysolutions.com/
*
* +Requires MooTools Core 1.2.2
*/
truncate:function(max, atChar, trail){
var s = this.trim();
if(s.length<1) return '';
if(!$defined(max)) var max = 100;
else max = max.toInt();
if(!$defined(atChar)) var atChar=' '; // break at space
else if(atChar == null) var atChar=false;
if(!$defined(trail)) var trail = '...';

if(s.length > max) {
var i=0;
if(atChar){
if((i = s.lastIndexOf(atChar)) != -1){
s = s.substring(0, i);
}else{
s = s.substring(0, max);
}
}

s += trail;
}

return s;
}
});
</pre>

Good call Michael! I have my own function (I bet many do) this is a
great addition!

Thanks Michael. We'll consider this for inclusion in String.Extras.

Got a few examples of the usage?

Simple as:

var elText = el.get('text');

el.set('html', elText.truncate(10, ' ', '...'));

[Michael Fuery]

Oops, I forgot a line in the code. Below "if(s.length > max)
{ var i=0; " insert this line:

s = s.slice(0,max);

Usage does not require any parameters at all if you are fine with the
default cut off of 100 chars with a trailing elipsis (...) and
truncate at space:

var str = "MooTools is an open source, lightweight, modular object-
oriented programming JavaScript web application framework released
under the MIT License. The goal of the software is to provide a means
for intermediate to advanced web developers to write cross-browser
JavaScript in an elegant, flexible, and efficient fashion. ";
alert(str.truncate());

// outputs: "MooTools is an open source, lightweight, modular object-
oriented programming JavaScript web..."
