Smalltalk Implementations

Each of the versions of Smalltalk is briefly described along with information about the source of the version and extensions provided by various vendors. Please note that the author works for one of these vendors.

Descriptions of commercial Smalltalk vendors are limited to a brief summary of which versions and what platforms are supported (taken from the vendors WWW sites), what addon products are available from the vendor, and information on obtaining more details.

Descriptions of other addon products are provided by the vendors themselves. If you have such a product and it is either not listed or the listing is not accurate, please notify the editor at the address listed at the front of this FAQ.

Descriptions of non-commercial versions of Smalltalk tend to be longer; again, the information is taken from the associated web sites.

The Smalltalk versions listed in this section are:

ANSI Smalltalk	22
Digitalk Smalltalk	22
GemStone Smalltalk	24
GNU Smalltalk	24

ANSI Smalltalk

What is ANSI Smalltalk?

ANSI Smalltalk is an incomplete and as-yet-to-be publicly proposed standard for Smalltalk. For information, see:

http://www.x3.org/tc_home/x3j20.html

What does ANSI Smalltalk cover?

The standard is expected to cover the language and base (non-graphics) classes including magnitudes and collections.

What doesn't ANSI Smalltalk cover?

The standard is not expected to cover graphics, windows, or platform dependent functions.

How do I get a copy of the ANSI Smalltalk standard?

There is no standard or publicly available draft at this time. One might be available in 1996.

Little Smalltalk

What is Little Smalltalk?

Little Smalltalk is not a Smalltalk-80 system, but is an experiment in building a minimal Smalltalk system. The source code for the interpreter is less than 1800 lines of code. The image consists of less than 4000 objects. It runs in almost no memory, it's reasonably fast, it's easy to understand, easy to modify, and runs on Unix. In order to get such a small Smalltalk to run there were some changes: From the web site In addition, there are Mac and Windows versions available from other parties.
