Hello,
In an earlier posting, I speculated if I could "breeze through"
learning the language in order to write an Eclipse plugin to implement an
editor, debugger, etc. Well, I can see now that learning Mozart/Oz, while
not impossible, is "not a breeze". I am essentially surveying the CTM book
at this point, skipping through the material to pick up what I can as a
"first pass". Now I am looking at Chapter 7, concerning classes. Here is a
basic question: how do I feed the following without an error message?
declare C in
class Counter
attr val
meth browse
{Browse @val}
end
meth inc(Value)
val := @val + Value
end
meth init(Value)
val := Value
end
end
C = {New Counter init(0)}
{C browse}
{C inc(1)}
local X in thread {C inc(X)} end X=5 end
A variation is to put the class definition in the part of the local
statement before the "in".

P.S.
Additionally, the following is an email that I got by posting to an Eclipse
user's group about incorporating a programming language into Eclipse. I
thought it may be interesting to share:
Here's more info on what SWT is: http://www.eclipse.org/swt/
If you are serious about developing an Eclipse plugin for any programming
language, you might want to start by talking to the CDE people, who
developed the C language eclipse plugin.
Implementing a programming language plugin is a huge undertaking, and you
need to think about many issues: editing with syntax highlighting,
compiling, debugging, etc.
You will have to get to know most of the components in the base of eclipse,
and you may discover that you need new functionality in eclipse itself,
which you may have to provide patches for and present your case for
including them in the base.
Your plugin itself will have to be written in Java - that is the language
for writing eclipse plugins, and that is the language for programming in
SWT.
The CDE newsgroup is: news://news.eclipse.org/eclipse.tools.cdt
You need to create a password to use it - this is to discourage spammers.
Try posting there to ask what is involved, and where to start.
Good luck, and hope this helps.
Carolyn
