Self on Smalltalk/V for Windows
===============================

Please note that this is unfinished and undocumented code!

This is a tiny contribution to the topic Self on
Windows. This is very old stuff which I never
documented or released. This is the code I experimented
with implementing Self on top of Smalltalk which I did
1995/1996.

It contains a parser written in Smalltalk which is capable
of parsing Self code. Unfortunately, it does not work on
transported generated code because that uses a special
object annotation syntax ({} = "") which this parser does
not support.

A special feature of this is that Self and Smalltalk objects
are tightly integrated, and you can send messages to Smalltalk
objects seamlessly within Self, and you can even send messages
to Self object from within Smalltalk using some "doesNotUnderstand:"
proxies. The reason why I did it that way was because I intended
using Smalltalk primitive objects like integers.

This program also contains a very basic GUI which is based on
Smalltalk/V windows containing a list of slots for a certain 
object, and a text input field on the bottom to edit the contents
of a slot.

The system contains an abstract syntax tree representation for
Self code (instead of bytecodes), and it has very basic evaluation
capabilities implemented with recursive Smalltalk code which
is propably going to bug if you like to support multi-threading
or exceptions.

This thing runs on Smalltalk/V for Windows 2.0, and I have implemented
it several years ago in two weeks on a 386SX notebook computer which
ran at 16Mhz, had a 40Gig harddisk, 12Meg memory and a 6" black&white
LCD screen. :-)

Also included are some experiments to do a Self parser with lex/yacc
which I did not get ambiguity free because as some other group members
have noted the Self grammar has some delicate features.

Please note also that I used mySelf as code name for these experiments
which should not be confused with another project called that name, too.

Have fun with it :-)
