macOS Internals

Understand your Mac and iPhone more deeply by tracing the evolution of Mac OS X from prelease to Swift. John Siracusa delivers the details.

You've got two main options:

The results of eval are not always data
The results of eval may be very large or deeply nested
We have strong data handling capabilities in Clojure, so how can we leverage them for non-data?
Practical consideration: need a console for Datomic Cloud
datafy: how to make data
nav: how to get more data
