Thank you very much fijal , you have clear me up a lot of confusions.

That's possible, although far in the future. Look here: http://moderator.appspot.com/ and search for pypy.

Very interesting , Do you think it will happen in next release of pypy , next 2-3 years? As speed (pypy-c) is already reaching to that of Cpython .

Have to use for what? If you want to participate in PyPy project, you probably need to know a bit about rpython, otherwise no, you don't. That can be gradual and relatively painless though :) (probably better han learning C or CPython's C API)

For contributing Pypy and If Guido retired , pypy may be at the level to be able to continue Python development via pypy (may be one real choice).

The simple answer is: they don't follow RPython. I'm pretty sure about this. You need to rewrite them from scratch, at least in parts for that. It's not very helpful.

i have some existing project which i would like to turn to C and compile . All i need to is to follow RPython right ? After that How can i compile to C ? Oh one question , what is pypy's JIT for ? And i will be joining to #pypy now. On 11/26/08, Maciej Fijalkowski wrote:

Hi Pypy Devs!

I love python so much and I am so exicted by this ambitious project!

What I understand about this Project is to develop a version of python , which is written in Pure Python . SO now , i do not have C Skills but I can Develop , Tweak , Make changes to python Just in Python , Am I Right? SO In Future , it is possible that Guido himself will be developing python in PyPy ?

That's possible, although far in the future. Look here: http://moderator.appspot.com/ and search for pypy.

Question : I have to use Python Or RPython?

...

Also By doing so , We can convert Python to Any langauge of Choice , which is very interesting.

No, only restricted subset of it, RPython.

...

I have build pypy-c with optimization Level 3 and stackless , whcih is done flawlessly. I have seen benchmarks on one of the page and now PyPy is even faster then Normal python 2.5 827 vs 810 ms on Richard Test, it is very interesting .

Question : Resulting pypy-c is python 2.4.1 , is there python 2.5 Version of pypy-c avaliable? I saw a branch about it before by a GSOC student but now is that already marged ?(my version svn is 4 days ago)

Yes, it's merged into pypy-trunk. Download it from svn from here: http://codespeak.net/svn/pypy/trunk/

...

If that arleady marged , how can i build it to get pypy-c with python 2.5 support?

Exactly like 2.4, just use trunk.

...

Another Questions is , If i follow my Python code in RPython , Can i converty RPythonic Code to C and compile ? SO it is possilbe to convert Existing Python Projects into C (if they follow Rpython)?

The simple answer is: they don't follow RPython. I'm pretty sure about this. You need to rewrite them from scratch, at least in parts for that. It's not very helpful.

...

Another , i compiled pypy-c in stackless , which is faster in term of pypy-c's perfomance? normal or stackless?

normal, although not by much. There is also an experimental option --gcrootfinder=asmgcc which makes it even faster, but does not cooperate well with ctypes for example.

...

Also doing , what are the extra modules added with --allworkingmodules ?

You should have list when you start compiling. For linux machine, it's:

["_socket", "unicodedata", "mmap", "fcntl", "rctime" , "select", "zipimport", "_lsprof", "crypt", "signal", "dyngram", "_rawffi", "termios", "zlib", "struct", "md5", "sha", "bz2", "_minimal_curses", "cStringIO", "thread", "itertools"]

(copy-pasted from file)

...

I am hoping in near future , i can help in this project after enough understanding .

You're very much welcomed to do so. Come on #pypy on IRC, it's better then mail sometimes.

...

Phyo. _______________________________________________ pypy-dev@codespeak.net http://codespeak.net/mailman/listinfo/pypy-dev
