Agora Implementations
There are several implementations of (several flavours of) Agora available.
The most recent version of Agora is Agora98. Agora98 is really . It was implemented in Java 1.1 and allows full access to the implementation 
 and to all Java API's. Feels great to dynamically open windows in your 
 webbrowser (by talking to the virtual machine in Agora98). Check out 
 the 
 agora98 homepage (we called it Agora98 because there is already an 
 Agora97, a modification of the C++ version.
Agora96. 
 
was implemented in C++ and allows full access to the implementation.  
Releases of Agora96 are available for 
Macintosh and Windows (NT & 95).  The application comes with several 
examples and a 90-page language manual. 
The first 'official' version of Agora was Agora94. 
A
Smalltalk implementation of Agora94 (implemented in Visualworks Smalltalk) 
can be fetched from our FTP-site. In the Agora94
directory you find
papers, 
a
manual, the Smalltalk file outs, examples and a paper giving a full
description of Agora94. Be sure to read the readme file
before installing the system!
Agora-S 
is a down scaled variant of Agora94 implemented in Scheme (hence the S). 
The difference between Agora-S and Agora94 is comparable to the difference 
between Scheme and more verbose functional programming languages like ML, 
Lisp or Haskell. Agora-S was designed to be a full-fledged programming 
language containing only a minimal number of constructs, much in the 
spirit of Scheme itself. 
Agora-S is a compiler compiling Agora-S code to Scheme. It is not 
very-well documented. Some minor documentation can be found on our 
WWW-site. The implementation can be FTP'ed for 
MacGambit.
In order to support our paper at ECOOP'95, a 
denotational semantics of 
Agora is
implemented in Scheme and in Gofer. It is a very tiny version of 
(non-reflective) Agora implemented
in order to
make our inheritance mechanism clear. This small language is called
MiniMix.
Those of you that have no time to learn 'full-fledged' Agora but
would like to
experiment with our inheritance mechanism are best off with MiniMix.
The
implementation, together with a few examples, is available in  
Scheme and in Gofer 
from our FTP-site.
