A Simple Messenger for IEx

This project is meant to be a very simple and basic example of process communication between nodes in a cluster using Elixir.

Installing

You can install the required dependencies with asdf (you'll need the elixir and erlang plugins).

$ asdf install

Running

You'll need to connect your node to a cluster. To do that, start the IEx session with the --name and --cookie options:

$ iex --name example@0.0.0.0 --cookie 123 -S mix

You can also use the included start script, that will execute the above command for you:

$ ./script node0 # iex --name node0@0.0.0.0 --cookie 123456 -S mix

By naming your nodes as nodeX, the .iex.exs will automatically try to connect with nodes node0 all the way to node9.

Using

The provided .iex.exs is already configured to import all functions from Messenger.IExClient.

Available commands

• signin [user]: sign-in in the cluster with the given user name
• signout: sign-out from the cluster
• whoami: returns the current user that's signed in
• inbox: prints the inbox
• sent: prints all sent messages
• last_msg: prints the last message
• msg [recipient], [message]: send the given message to the recipient
