Diff output of two lldb commands

Setup

1. Copy the contents of the last snippet (lldbinit) from the gist page, and paste into your .lldbinit file. This makes the ksdiff macro known inside lldb.
2. Put file ksdiff.py in ~/.lldb/
3. sudo pip install temp
4. Restart Xcode debug session

Example

(lldb) ksdiff ;

/**
 Provides the ability to verify key paths at compile time.
 
 If "keyPath" does not exist, a compile-time error will be generated.
 
 Example:
    // Verifies "isFinished" exists on "operation".
    NSString *key = SQKeyPath(operation, isFinished);
 
    // Verifies "isFinished" exists on self.
