Chat Server Submission

Introduction

This project was part of a TCD college assignment to create a chat server for clients to chat using a protocol to perform actions in a chatroom just as join a chatroom, send chat messages, leave chatrooms & disconnect from the server. Also a "HELO base" message is sent which server returns the IP of TCD Macneill machine and student number.

I will discuss the protocols and showcase clients using the chat server below.

HELO base Message

Sending the HELO base message required the user to send the following commands to the server

HELO text\n

User sending HELO text Message

Joining Chatrooms

Joining a chatroom required a user to to send the following commands to the server once they connected (I implemented for TCP).

JOIN_CHATROOM: [chatroom name]
CLIENT_IP: [0 for TCP]
PORT: [0 for TCP]
CLIENT_NAME: [string Handle to identifier client user]

User Joining

Sending Chat Messages

Sending a chat message to a chatroom required a user to to send the following commands to the server once they were a member of a chatroom

CHAT: [ROOM_REF]
CLIENT_NAME: [string identifying client user]
MESSAGE: [string terminated with '\n\n']

User Chatting

Leaving Chatrooms

Leaving a chatroom required a user to to send the following commands to the server once they were a member of that chatroom

LEAVE_CHATROOM: [ROOM_REF]
JOIN_ID: [integer previously provided by server on join]
CLIENT_NAME: [string Handle to identifier client user]

User Leaving a Chatroom

Disconnecting From Server

Disconnecting from the server required a user to to send the following commands to the server

DISCONNECT: [0 for TCP]
PORT: [0 for TCP]
CLIENT_NAME: [string handle to identify client user]

User Disconnecting from Server

Running on your machine

1. Clone this repo git clone https://craig1901/complexity_api
2. stack build inside the directory
3. bash run <port> to set up a local server on your machine on the given post
4. telnet localhost <port> to make a connection to the server and start chatting!

Notes Regarding given test service for this Assignment

All runnable code is on restart branch of this repository!

Got 64% in the tests:

• I couldn't figure out how to get the HELO base message to get sent fully back, all the client got back was the letter H from my response which was wierd I thought (again works when I run on my computer!)
• Test suite wanted to be sent back a chat message that a client has left a room when they disconnected, mine disconnects and clients are removed from their respective chatrooms
