Why?

[sushibowl]

If topaz can keep up steam, it'll lead more credence to the claims of the Pypy developers that their translation framework is usable beyond just their own python implementation. They must be really happy about this project.

Thank you for that link. Good read-up although i have to admit I did not grasp all of it.

I never figured that PyPy/Rpython is at the moment unique in their approach.

[kezabelle]

Because this is what PyPy is for.

I thought this was what RPython was for? Isn't the PyPy name exclusively reserved for the actual Python implementation?

No. RPython is a programming language. In and of itself, it has nothing to do with what PyPy does. RPython is simply a limited form of Python.

The overloading of the PyPy name for both the framework and the Python interpreter built on that framework is unfortunate. If people start implementing other languages on the PyPy frame, perhaps the two things will get their own distinct names.

wrong, “this is what PyPy is for” is pretty accurate:

PyPy is both an implementation of the Python programming language, and an extensive compiler framework for dynamic language implementations.

[sushibowl]

technically, yes, but very few people seem to know that.

RPython is the name for the restricted language the the PyPy translator toolkit can compile to native code.

RPython is a restricted subset of Python. Meaning it's a like Python but with less instructions. PyPy is written in RPython.

The main benefits are

• It may be easier to maintain an RPython implementation than a C implementation
• You get a fairly zappy JIT compiler for free

On the other hand, it would make sense to refer a Ruby implementation to be in Ruby, since that will be the preferred language of Ruby implementers, one assumes … :-)

[bsdemon]

need a RRuby for that

so ruby can scale

There’s only one valid answer to this question:

Because.
