Demos

Little demos of how Elixir works.

Each module in /lib is a demo. To run one:

• iex -S mix
• Maybe :observer.start() and/or open Activity Monitor or whatever you use to watch memory usage on your OS
• Run a demo - for example, Demos.Mailboxes.go()
• Maybe tweak the code, recompile, and run again

Planned Topics

• Processes can send and receive messages by pid - Demos.SendAndReceive
• Processes have mailboxes - Demos.Mailboxes
• Processes recurse to keep state - Demos.KeepingState
• Processes are preemptively scheduled - Demos.Scheduling
• Links and monitors
• GenServers manage listening, replying, keeping state, and more
  • Demos.AutoCounter
  • Demos.CallAndCast
• Supervisors use links and monitors
  • Demos.Supervisors
  • Demos.SupervisorsAgain
