Funky

Funky is a functional utility library written in Objective-C.

It provides a set of extension methods on NSArray, NSDictionary and NSSet for you to help dealing with common operations (usually in a functional way).

Documentation

Full documentation is available at tevelee.github.io/Funky

Usage

The framework contains a set of extension methods on NSArray, NSSet and NSDictionary.

Using them is as simle as

NSArray<NSNumber*>* numbers = @[@1, @2, @3];
NSArray<NSString*>* strings = [numbers map:^id(NSNumber* item) {
    return item.stringValue;
}];

or

bigNumbers = [numbers filter:^BOOL(NSNumber* item) {
    return item.intValue > 1000;
}];

For the full list of utils, please check out tevelee.github.io/Funky

The framework includes some cool nil-tolerant collection behaviours as well:

NSArray* array = @[@0, @1, @2].nilTolerant;
NSLog(@"Items: %@", [array arrayByAddingObject:nil]);

Again, see the docs for more details

Help & Bug Reporting

In case you need help or want to report a bug - please file an issue. Make sure to provide as much information as you can, sample code also makes it a lot easier for me to help you.

Contribution

Anyone is more than welcome to contribute to Funky! It even can be an addition to the docs or to the code directly, by raising an issue or in form of a pull request. Both are equally valuable to me!

Future plans

Roadmap

• Figuring out ways for lazy collections, so the order of map/filter/take won't matter and always compute only the most necessary computations. So if you operate a map function on a huge array, but at the end you filter only for a few, the mapping should only take effect on the very few you needed.

General guidelines

• Active maintenance
• Keep the >95% test and documentation coverage
• Accepting suggestions and pull requests from the community
