yahmini

yahmini is a small (really small) yahoo chat client with basic features.
It is designed primarily for viewing chat text. It decodes all known yahoo packet types in common use and provides colored output if you have the *NIX version, or if you have the WIN32 version and have ANSI.SYS installed.
Yahmini is known to run on Win95, Win98, Win2k, NT4, Linux, BSD and possibly Solaris.
C source code is available.

yahmini provides access to a few commands:

send text
/quit
/color
/away reason
/goto person
/call person (invite)
/join room
/roll #dice
/tell person privatemessage
/think text

A screen snapshot shows it in action.
The *NIX version looks almost identical.

It is amusing to note that the yahmini.exe program is less than half the size of the screen snapshot. The screen snapshot is 28KB, while yahmini is about 12KB.

You can
download yahmini.exe for win32
or
download yahmini for Linux

Using yahmini

You can just start it up and it will ask for

username
password
roomname

or you can supply all the information on the command line:
yahmini Joe2000 sesame "Chat Central"

If you leave off any arguments on the command line, it will prompt you for them.
An empty argument "" (a pair of doublequotes) will cause yahmini to ask for input
yahmini Joe2000 "" "Chat Central"
will prompt for the password.

The full command line possibility is:

`yahmini name pass room color showmove showaway pingtime`
name	yahoo login name (32 chars max)
pass	yahoo password (32 chars max)
room	the room to start in (32 chars max)
color	the single letter 'y' or 'n' for color
showenter	the single letter 'y' or 'n' to show people entering or leaving the room
showaway	the single letter 'y' or 'n' to show people away/back
pingtime	a single digit '0' to '9' sets the ping interval in minutes

Yahmini will display color on *NIX systems if you enable it and have a color terminal.

Yahmini will display color on win32 systems running command.com with ANSI.SYS loaded.
To enable color on win32, add the following line to your C:\config.sys
device=c:\windows\command\ansi.sys
ansi.sys is a standard driver included with dos and windows, it provides ansi color terminal ability for dos sessions.

About yahmini

yahmini was an experiment to see how small a yahoo chat client could be. The distributed version was created with a custom 'C RunTime' that I wrote. From a programmers view the executable size of yahmini is phenomenally small, a standard C 'hello world' program is usually much bigger ~30KB or so, so it is suprising to see a functional chat client in such a small package.

Source Code

Yes, source code is available.

Yahmini is written in portable C using standard Berkley style sockets. The *NIX and win32 versions both use
yahmini.c and yahmini.h
For *NIX also use nix.c and nix.h with the makefile
For Win32 also use dos.c and dos.h

They are available bundled in a zip archive
