/**
 * Ensure Public API Has Tests
 * ---------------------------
 * This demonstrates analyzing code to find methods and properties from the public
 * api that don't appear in the tests.
 * 
 * This is a very basic implementation... a better implementation would examine more
 * aspects of the code (ex. are the return values properly checked?) and report
 * statistics about the tests that possibly indicate how they could be improved (ex.
 * "this test has a lot of overlap with these other tests"). The goal would be to

The attached lldb command pblock command lets you peek inside an Objective-C block. It tries to tell you where to find the source code for the block, and the values captured by the block when it was created.

Consider this example program:

#import <Foundation/Foundation.h>

@interface Foo: NSObject
@end

@implementation Foo

The dynamic wallpaper in MacOS Mojave is a single 114 MB .heic file that seems to contain 16 embedded images.

It also contains the following binary plist data in its metadata under the key "Solar". It's an array of 16 items, each with four keys:

• i (integer). This seems to be the image index.
• o (integer). This is always 1 or 0. Stephen Radford thinks it indicates dark mode (0) vs. light mode (1).
• a (decimal). I’m pretty sure this is the angle of the sun over the horizon. 0º = sunset/sunrise. 90º = sun directly overhead. Negative values = sun below horizon.
• z (decimal). This seems to be the cardinal position of the sun relative to the camera. 0º = sun is directly in front of the camera. 90º = sun is directly to the right of the camera. 180º = sun is directly behind the camera.
