ObjectiveCVerbalExpressions is a Objective-C library that helps to construct difficult regular expressions - ported from the awesome JavaScript VerbalExpressions.

pod 'VEVerbalExpressions'

Drags VerbalExpressions.h and VerbalExpressions.m into your projects and import "VerbalExpressions.h"

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
VerbalExpressions *tester = VerEx()
.startOfLine(YES)
.then(@"http")
.maybe(@"s")
.then(@"://")
.maybe(@"www")
.anythingBut(@" ")
.endOfLine(YES);

// Create an example URL
NSString *testMe = @"https://www.google.com";

// Use test() method
if (tester.test(testMe)) {
    NSLog(@"%@", @"We have a correct URL"); // This output will fire
} else {
    NSLog(@"%@", @"The URL is incorrect");
}

NSLog(@"%@", tester); // Ouputs the actual expression used: "^(http)(s)?(:�_/�_/)(www)?([^ ]*)$"

NSString *replaceMe = @"Replace bird with a duck";

// Create an expression that seeks for word "bird"
VerbalExpressions *verEx = VerEx().find(@"bird");

// Execute the expression like a normal RegExp object
NSString *result = verEx.replace(replaceMe, @"duck" );

NSLog(@"%@", result); // Outputs "Replace duck with a duck"

NSString *result2 = VerEx().find(@"red").replace(@"We have a red house", @"blue");

NSLog(@"%@", result2); // Outputs "We have a blue house"

I haven't added much documentation to this repo yet, but you can find the documentation for the original JavaScript repo on their wiki. Most of the methods have been ported as of v0.1.0 of the JavaScript repo. Just be sure to use the syntax explained above rather than the dot notation :)

Clone the repo and fork! Pull requests are warmly welcomed!

• I haven't yet ported the stopAtFirst method.

Thank you to @jehna for coming up with the awesome original idea!
