gChat

Chat program with room to improve

The software is composed by three different files:

1. Input client (cl.c)

2. Visualizer/output client (vis.c)

3. The server (ser.c)

1 - The client

This is like an input box for the chat, you won't see any output here.

1.1 - conf.txt

The first time is executed the client will crete a file conf.txt and ask you to compile the host and nickname field. Conf.txt can be modified inside the folder of execution.

1.2 - Commands

You have some useful services that the client can ask to the server (don't write the []):

/admn [password]

This command will make you and administrator(if you know the password for the server), quite lame state for now but you will be able to execute the next command:

/cast [something]

You will broadcast everything inside the brakets, on every chatroom.

/prch [room] [room_password]

You will create or enter (if already exist) a private room; the password field is optional, if entered the room will be protected by password, set this entry to 0 is the same of leaving empty.

/prrm [put something]

You will destroy the private room and send every user back to "plaza". You need to be an admin.

/pass [something/room_name]

Normal user: will send back the password of the current room (NEED to put something to work).

Admin user: will send back the password for the room entered.

/nick [new nick]

You will be able to change your nick in the server, is only a temporary change, the default nick can be changed in the conf.txt file

/end

Close the client. You can also use Ctrl+C.

2 - The Visualizer

The visualizer work with the same conf.txt file of the client so be sure to put it the in the same folder.

You will be asked to enter a room, leave blank or "plaza" and you will enter the default room of the server. The room must be created from the client before be entered.

3 - The server

The server do everything by itself, the first time is executed it will create the file ser_conf.txt where you can put the password for admin, after it will start on port 9734;

The - means that the "Hall" is waiting a client to join and be dispatched in some room.

The !name of room! mean the room is waiting for an input

The output is formatted this way: nameOfRoom, |nick| message
