[ In response to Mark Evans' query about the various versions of Icon: ]
We (Ralph Griswold and Gregg Townsend) maintain the "master source copy"
of Icon at the University of Arizona. The source code is distributed as
part of packages configured for particular platforms. Periodic updates
are available by subscription.
We also produce and distribute the source and binary packages for Unix
and provide web/FTP space for other platforms. The Icon web site is at
http://www.cs.arizona.edu/icon/
and it includes a list of versions available for various platforms.
We regard Icon as a mature language and we have no plans for major
changes or additions.
Clint Jeffery of UT San Antonio maintains the Windows version of Icon.
This is also a released product, but work continues on a more active
basis. See
http://www.cs.utsa.edu/research/icon/
Clint also distributes Idol, an object-oriented variant of Icon.
Unicon, from Shamim Mohamed, adds many POSIX-inspired built-in functions
to Unix Icon. It is available through his web page at
http://www.drones.com/unicon/
Todd Proebsting and Gregg Townsend are actively working on Jcon, a new
Java-based implementation of Icon, and intend to release a new and faster
version later this year. We don't know where this will ultimately lead.
See
http://www.cs.arizona.edu/icon/jcon/
These are the versions of Icon that have been in the news lately.
There may be other things going on that we're not aware of.
