Re: what is the best language for go: Re: [computer-go]Scoreestimating

I think this computer language discussion is probably stretching the patience of people whose main interest here is computer Go so I'll try to make this my last post on the topic :-)

Regarding Mark's question about large scale development: I'm not sure how Ruby would fare there. It has pretty decent OO features (better than Python IMHO) which should help. My biggest Ruby program to date is only about 500 lines and it is certainly fine for anything of that size.
I really go back to read the Ruby OO features, I did not found anything that don't exist in python. Maybe you can give me good pointers on web.
The things I didn't like about Python's OO were:
- lack of private and protected instance variables
- having to use an explicit 'self' parameter in all methods

Note that I'm not saying Python is a bad language, just that I personally didn't like it much. I'm sure that lots of people do wonderful things with Python. I'm equally sure that a sizeable bunch of people will prefer Ruby.

cheers,
Peter



I'm not sure why it wouldn't be OK for bigger programs (ie. a Go program) 
as long as you're prepared to live with dynamic typing and code up plenty 
of Unit tests.  I'd still see it as potentially much more productive than 
C++ or Java.  I agree that speed would be an issue - if you do a serious 
Go program in it I'm guessing you'd want to re-implement the critical 
parts in C once they've stablised.


I'm sure that Python can manage such programs.
For that there is a similar paquages as in java,
but the import system is even more powerful than java one.

Personnaly I know Python only since six month
and I already made a full working application (even if not finish)
which has 888 lignes wich is perfectly extensible and stable.
It includes: configuration, special ftp client, language source detection
C code processing, batch compilation (with system ("gcc ") calls)

Biggest aplications full works.
mailman  (mail list manager) 33 000 lignes of code.
Zope (web server and web development environemnt) 403 000 lignes of code.

And the point is to realize the same functionnality,
the code is *really* shorter than java or C++.
For exemple, in my project, with the help of introspection,
I parsed a file, transform it into a full working Python object,
add one simple unittest, all in one file of 79 lines.
As far as I remember how I worked in java, I would expect
that the same job in java would require at least three
classes (one file for each) 80 lines each.
That's why I rely believe that Python is three times more productive
than java (even including the learning stage)

So I don't think that big project in Python is an issue
The integration with C is easy (but not tested personnally)

So I think it meets better the requirements of go application
than C or java. Maybe Lisp is even better, but I know very
little about lisp, except that it is harder to learn.
