Simple chatroom application written in Go

Usage

• For server, type ./gochat server host:port to start the server. If running the server locally, you can omit the host part.
• For client, type ./gochat client host:port to enter an existing chatroom. Then type your chat name(required) to start chatting with others. If running the client locally, you can omit the host part.

TODO list

• Currently the server can't handle the case when two clients have the same UserName. This is because in Server.handleBroadcast(), I use UserName to distinguish different clients. The solution is to use conn.RemoteAddr().String() as the key of the map, however, this would require an extra map of RemoteAddr -> UserName in order to get the clients' name. It will require another map of if UserName -> RemoteAddr if we are to support mention(@) functionality(consider the case @dahuang hello, how to direct this message to dahuang only). The current solution thus seems to be the most cost-efficient one.

• default port, don't bother user to decide it
