Again, after the posting on CO2 two weeks ago, I post this (long) reply on
request of a friend who has no access to usenet facilities.
So, please, respond to him directly:

Dear readers
The posting about CO2 of 2 weeks ago raised some
questions that I would like to answer with this posting.
>That looks pretty hot, but is it "CO2" or "Co2"?
>James "Greenhouse" Salsman
The name is derived from C Object Oriented,
and is thus CO2. If you could see my original Macintosh
derived file, you could also see the subscript. Unfortunately
subscripts are a luxury in most computer systems. About
the greenhouse effect, I can assure you that it is very hot, but
of the kind which does not harm the environment.

As I told in my message about CO2, there are not
many differences between CO2 & Objective-C. But there
is one very important difference, which is that
the sources are NOT preprocessed. You can use any
C-source and compile and link it in any CO2
application, I will try to explain how we did it by
showing the activities to create a method in a class.
The main difference with Obj. C is that all the
definitions are maintained in a separate file (a <app>.s
file). This file is run through Syntor which generates
a <app>.c file that can be processed by any C compiler.
The sources of the Syntor program are standard C again.
If I want to create the message foo(a,b,c) in class
Bar, the I enter the following definition in the .s
file:
>Object::Bar
{
data{int xyz;}
message foo;
};
Object::Puppet
{
data{int abc;};
message foo;
};
This is translated by Syntor to the following:
(functionally anyway)
foo(self)
{
tableType t={
Puppet, om_Puppet_foo,
Bar, om_Bar_foo };
dispatch(self, t);
}
This means that methods from the same message are
grouped together. In objective C the methods of a class
are grouped together, which explains the need of message
routine.
It is true that you need syntor to preprocess the .s
file into a .c file. But when you are writing the
application code this is rarely needed. It is only
done when messages are added or instance variables are
changed. So the big advantage over Obj. C is that
turbo-c, quick-c and those other easy to use development
environments with built-in editors can still be used.

I hope that this explains your questions. If it is
still not clear, or if you disagree with my arguments,
please let me know.

As I explained in the original story, CO2 is not a
product. We have used it to develop a page-make up
terminal for the newspaper market. Unfortunately we are
not in the business of selling this kind of software. We
have a debugger, windows system, collections and much
more.
But only a part of it is documented good enough to
sell. We have therefore taken a part, the basic object
system with: Bags, Sets, Ordered collections, Sorted
collections, Array, Bytecollections, Strings, Dictionary
and some other minor classes, and made a dos-diskette
of it. If this generates enough interest, or if some
componay would like to make it into a product then
we are willing to supply the remainder of the code.

The scheme we have been using is intriguing. It uses
a mental switch because the way we have done it is
90 degrees from the smalltalk, C++ and objective C
approach. Smalltalk started by grouping the messsages
into a class
Class Foo (Anybody knows where Foo comes from?)
abc
def
Class Bar
abc
To find the correct method for a message Smalltalk looks
into the dictionary of the class of the receiver:
receiver -> class -> method dictionary
|
message -> +
|
method
In CO2 which grouped the methods with the same name
and indexed them on class.
abc
Foo om_Foo_abc
Bar om_Bar_abc
def
Foo om_Foo_def
The grouping is done by using the C linker. A message
is a procedure. This procedure looks like:
abc(self)
{
tableType t={
Foo om_Foo_abc,
Bar,om_Bar_abc };
dispatch(self, t);
}
The dispatch routine looks in the table, locates the
class of self in that table and finds the correct
procedure (method). In real life it is a little bit
more complex because the dispatching is done using a
packed trie that is optimized with some tricks. This
means that the lookup is done with 2 indexes. This lookup
also handles the super send, does not understand and the
full inheritance.
The advantage this way are plenty. First a normal C
compiler can be used because a message has become
a normal procedure call. Second there are much less
methods per message (CO2) than methods per class.
(Smalltalk).
I have included the sources of Syntor at the end.
These are not the sources of account.s but of a
comparable program. It put them at the end because
it is pretty much and quite unreadable. I also
included the file syntor.h so that you can translate
the macro's. Goodluck.

CO2 is not a standard product, shrinked wrapped and the
like. I have prepared a DOS floppy for the turbo C
compiler that contains the sources of a basic system.
Received: From the interest that this generates depend our action
to make it a full blown product. (I would love to see
it in a shrink wrapped version!).
About Unix and other environments I can tell you that
we have it running under RMX (one of the best O.S. in the
world), Sun road runner, Macintosh, DOS (turbo-C) and the Watcom
C compiler for the phar lap tools. Portability is very
good because we use a subset of ANSI that is almost
completely compatible with Kernighan & Ritchie. We
use full prototypes but they can be removed by defining
some macro's.

It is not a crippled version. It demonstrates CO2 and
you can use it to build life systems, as I have done many
times. It is no complete product and has no manuals. So
you can get it at your own risk. But the first version
is only available for dos. To obtain the product
you can send a Fax to
Mediasystemen
31-23-315210 (holland)
Please put the following words in the Fax
We hereby ask you to send us a demo
version of CO2 for dos. We will not use
anything from this product for resale
to any other party.
Please specify mastercard number and expiration date
for the $50.
>Is it available for ftp somewhere? Could it become so?
>How large is it (that is, could it be shar'd and mailed to comp.sources)?
>
> kipp hickman
Unfortunately we do not have such facilities. But please
refer to the previous question to see how you can
obtain the demo diskette.
I sure hope that I have answered the questions
in a way that is understandable. Please realize that
part of this work is hobby for me. As told before
Mediasystemen is in the business of selling editorial
systems and not software. but we think that this
product is so nice that it should be shared by others.
If there are more areas where I have not been clear,
pleas send a mail to me and I will answer it
as soon as possible.
