Small Chat App

Hi all,

Raining sunday ;-)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

"In Pharo 3.0"

Gofer it

smalltalkhubUser: 'LucFabresse' project: 'Grimoire';

package: 'ChatApp';

load.

ChatApplication startLocalExample.

ChatApplication stopLocalExample

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This a 1st draft version of a Chat Application that works. It is implemented in plain Socket with an ad hoc text protocol.

a *lot* should be improved, done or added:

- write tests (it is always a pain to write for client/server apps so here I skip them :-()

- ensure that everything is correctly destroyed/cleaned (processes, sockets, streams, ...). it seems but... needs testing

- refactor to use SocketStream?

- better modularization of commands

- another implementation using Zinc but it would imply using HTTP

Enjoy,

Luc

Nice hack, luc.

I would use WebSockets.

Here is a live example

http://websocket.stfx.eu:9999/ws-chatroom-client

The implementation is part of Zinc-WebSockets. It is just 1 class: ZnWebSocketChatHandler.

Hi Sven,

Very nice!

Thanks for the pointer.

I will read your implementation and learn because my Network skills are limited ;-)

Cheers,

Luc

Luc

please keep the different versions because it can be quite cool to teach and compare solutions.
