JavaScript Regular expressions made easy

VerbalExpressions v0.1

VerbalExpressions is a JavaScript library that helps to construct difficult regular expressions.

You can see an up to date list of all ports in our organization.

Include the library and you're good to go!

<script src="VerbalExpressions.js"></script>

Here's a couple of simple examples to give an idea of how VerbalExpressions works:

// Create an example of how to test for correctly formed URLs 
var tester = VerEx()
            .then( "http" )
            .maybe( "s" )
            .then( "://" )
            .maybe( "www." )
            .anythingBut( " " )
// Create an example URL 
var testMe = "";
// Use RegExp object's native test() function 
if( tester.test( testMe ) ) alert( "We have a correct URL "); // This output will fire 
else alert( "The URL is incorrect" );
console.log( tester ); // Ouputs the actual expression used: /^(http)(s)?(\:\/\/)(www\.)?([^\ ]*)$/  
// Create a test string 
var replaceMe = "Replace bird with a duck";
// Create an expression that seeks for word "bird" 
var expression = VerEx().find( "bird" );
// Execute the expression like a normal RegExp object 
var result = replaceMe.replace( expression, "duck" );
alert( result ); // Outputs "Replace duck with a duck" 
var result = VerEx().find( "red" ).replace( "We have a red house", "blue" );
alert( result ); // Outputs "We have a blue house" 

You can find the API documentation at the wiki pages.

I'd like to promote a special thank-you to Ben Nadel for his great article about extending native JS objects
