Hi all!
I'm thinking about implementing a ruby to python translator (this is a
program that takes a ruby program and generates its equivalent program
in python). In order to get started, I would like to know if there is
a ruby grammar implemented in python or with another tool.
The final idea for the project would be to run ruby code on the OLPC.
Can you give me any pointers?

None that I know of outside of ruby.

Why not run ruby on OLPC? Just to avoid the extra install?

You might have a look at the "Ruby top down Grammar" project. It is a
hosting language neutral Ruby grammar. You might translate that
grammar
to a Python recursive descent parser or interprete the grammar from
some
Python code. If you know Python well that should be doable in a few
days
time. Be warned that you would be the first client of this grammar.

I'm translating Ruby to Javascript and use ParseTree for that. Python is a little less dynamic than Ruby, so for example AFAIK Python doesn't execute module-level code when it is loaded as Ruby does. That means that you can't simply convert Ruby to Python code 1:1. What I am doing with RubyJS (my Ruby to Javascript compiler) is to first evaluate the Ruby code (all meta-programming stuff is going on here) and then compile each class to Javascript. This is very powerful.
It should be easier to compile Ruby to Python than it is for compiling Ruby to Javascript. But I'd be more interested in compiling Python to Ruby, which should be even easier.

From what I've heard and seen of Javascript, I'm not sure that the
opposite isn't true.
Javascript gets much less credit than it deserves.

That's what I was looking for, tanks.

Yeah! But it's a lot more important that seems like an entertaining project.

IMHO Python has a much better underlying model, just take Javascript "null"
special values. They are not objects! This makes it harder to compile from an
"everything is an object language" to Javascript. Just one example
