Clone the repository on each local computer that will be using the network (all clients and the server). Install requirements with pip install -r requirements.txt

Run python3 server.py in base directory. This will allow the server to start listening to new clients that join and their commands. As clients join and make requests, important updates will be printed to the server command line.

Run python3 client.py in base directory.

Upon signup, you will be asked to enter your username. If you have an existing account, you will be logged into that account assuming no one else is logged into that account, otherwise a new account will be created with your associated IP.

To list accounts, you may either use the built-in list|all and list|active commands that list either all users in the network or just active users, or any character/set of characters ie. list|g.

To send a message, you must use the following structure: list|recipient_username|message. If your command has a valid recipient username, then one of two events will occur.

1. If the recipient is active on the network, the message will be sent immediately, and you will be notified whether the message was successfully sent. 
2. If the user is inactive, the message will be queued for their viewing when they sign back in. 

If the recipient username does not exist in the network, you will be prompted with sending a new command.

To remove your account from the network, type the command "remove". This will remove your account and disconnect you from the network.

Clone the repository on each local computer that will be using the network (all clients and the server).

Run python3 -m server in base directory. If successful, you'll see a Starting server. Listening.... This will allow the server to start listening to new clients that join and their commands. As clients join and make requests, important updates will be printed to the server command line.

Run python3 -m client in base directory.

Upon starting up the client, you'll be given the options to either sign up or log in. The prompt will specify the available commands Enter 1|{Username} to sign up or 2|{Username} to log in:.

There are mechanisms in place to ensure successful login: you must enter a valid input, you can't sign up with an existing username, you can't log in to a nonexistent user, and you can't log in to a user already logged in elsewhere.

Once successfully logged in, you'll be given the following command options: Commands: \send to send a message, \logout to log out, \list to list accounts.

To send a message, input the \send command. Then, you'll be prompted to specify a recipient and a message. Both must be non-empty.

If the recipient is active on the network, the message will be sent immediately. If the recipient is inactive, the message will accumulate in a queue to be sent once they log back in.

If the recipient username does not exist in the network, you will be prompted with sending a new command.

To list accounts, input the \list command. You will then be prompted to give a query. This query may either be empty or a string. The terminal will then print out all usernames that begin with the query.

To log out, input the \logout command or Ctrl+C for a keyboard interrupt. Once logged out, the server will show that the user has the chat and the client will return to the original signup and login prompt.

To log out, input the \delete command. The terminal will then prompt you for confirmation. If you confirm with y, then your account will be deleted and the client will return to the original signup and login prompt.
