Is there a native YAML library for iPhone?

Question

I'm considering using YAML as part of my next iPhone application, but I haven't been able to find an Objective-C library to use.

The Wikipedia page for YAML mentions one, but the link is dead.

Is there an Objective-C library that can parse YAML into native collection objects (NSArray, NSDictionary, etc...)?

Answer 1

I found this right from YAML's front page. But it looks like it might be out of date (c. 2004?), and the CVS link doesn't work for me.

I would bet that it's just a thin wrapper around an underlying C library like this or this... C code being "native" code that the Objective-C compiler will grok.

The Cocoa extensions for Syck are probably what you're looking for -- it's where the library that Shaggy Frog mentioned seems to be living these days.

Answer 3

The YAMLKit framework is a thin wrapper around LibYAML. It does exactly what you want. For example:

[[YKParser alloc] init];
[p readString:@"- foo\n- bar\n- baz"];
id result = [p parse];
/* result is now an NSArray containing an NSArray with elements:
   @"foo", @"bar", @"baz" */
[p release];

Answer 4

You can try YAML.framework it's LibYAML based, it's fast and easy to use. Follows the same pattern as standard NSPropertyListSerialization.

You can use it for iOS (iPhone/iPad) development.
