String Regular Expressions with MooTools

Whether you like given JavaScript library or not , there are always snippets you can take from the code which accomplish a task you may need to address.  We all know that I looooooove MooTools, but maybe you're a Dojo or jQuery developer that doesn't get a good look at Moo.  The following are a choice selection of regular expression used with MooTools -- maybe you have use for them?

Clean Whitespace

var newString = myString.replace(/^\s+|\s+$/g, '');

Camel-Case a Dash-Separated String

var newString = myString.replace(/-\D/g, function(match){
	return match.charAt(1).toUpperCase();
});

Dash-Separate a Camel-Cased String

var newString = myString.replace(/[A-Z]/g, function(match){
	return ('-' + match.charAt(0).toLowerCase());
});

Escape a Regular Expression

var newString = myString.replace(/([-.*+?^${}()|[\]\/\\])/g, '\\$1');

Hex to RGB, RGB to Hex

var hex = myString.match(/^#?(\w{1,2})(\w{1,2})(\w{1,2})$/);
var newString = (hex) ? hex.slice(1).hexToRgb(array) : null;

Term Substitution

var newString = this.replace(regexp || (/\\?\{([^{}]+)\}/g), function(match, name){
	if (match.charAt(0) == '\\') return match.slice(1);
	return (object[name] != undefined) ? object[name] : '';
});

Strip Scripts from a String

var newString = myString.replace(/<script[^>]*>([\s\S]*?)<\/script>/gi, function(all, code){
	scripts += code + '\n';
	return '';
});

Above are just a sampling of regular expression used by MooTools to accomplish tasks.  Most, in fact, are applied as methods to the String native so they are available with *ANY* string!
