An OSX program to journal which applications are currently at the forefront of the focus stack.

Found focus would randomly change for a few second occasionally. I found a Python script on a StackOverflow post however it polled every second instead of using events. Thought writing a similar program in Golang would be an interesting way to learn about cgo and it sure was.

Running go build -o appwatcher ./cmd will generate the binary. Placed most of the correct code in pkg under the OSX framework it is related to. You will need to compile it on OSX to build successfully.

NotificationCenter is actually in Foundation however in this case it is strongly bound to the notification of activation changes for applications. So in my case it didn't make sense to further factor out.

Welcoming contributions which improve either the appwatch application or the bindings against OSX specific frameworks.

Need to journal the data somewhere useful, such as Postgres or a SQLite type database. This will allow review of the applications and filtering. Might make sense to continue building out appkit and foundation library.
