scheme interpreter
by Jakub Gustak April 23, 2007

April 23, 2007

I think, it's about time for me to say hello! I am in the game for Google Summer of Code. I will be working on Scheme interpreter/front-end during this summer. Armin Rigo is my mentor. Right now I am doing more research on the subject and getting familiar with PyPy code base. The main issue right now is: How to start with PyPy? In short time we will have discussion on some basic ideas about the interpreter itself. We will probably use #pypy-scheme on IRC, to not to disturb the regular discussions on PyPy development. It is really great opportunity for me to work with you. Best regards, Jakub Gustak

Embedding pypy
by Lalo Martins April 22, 2007

April 22, 2007

Here's an interesting question... how hard would it be to write a C API for embedding the pypy VM in a C or C+ + application? I have an application for which I'm working on Python scripting, but for many reasons it would be interesting to use pypy instead. best, Lalo Martins -- So many of our dreams at first seem impossible, then they seem improbable, and then, when we summon the will, they soon become inevitable. ----- personal: http://lalo.hystericalraisins.net/ technical: http://www.hystericalraisins.net/ GNU: never give up freedom http://www.gnu.org/

Should we decide to have another seminar in Gbg ...
by Laura Creighton April 22, 2007

April 22, 2007

we should remember to invite this person: http://www.cs.lth.se/home/Calle_Lejdfors/ posted here, so we don't lose it. (Plus you might want to read his papers.) Laura

Javascript parser
by Florian Schulze April 20, 2007

April 20, 2007

Hi! I read that some people here may work on a javascript parser. I'm also working on one, so I would be really interested in collaboration. Especially with people who have more experience with compiler and interpreter needs. I only have the need up to an AST and generating javascript from that again. I just need some transformations which may get more complicated though. Just contact me, Florian Schulze

SciPy conference August 14-18 at Caltech
by Laura Creighton April 20, 2007

April 20, 2007

Anybody here going? Even if we don't make a pypy presentation, we should probably make a poster/hand out. This conference is a likely source of the kind of people who do the sort of algorithmic computing that we can expect to best optimise. It would bt nice to get some speedup figures from them. Laura

Re: [pypy-dev] scheme interpreter

I regularly read the logs of #pypy for when I cannot be around. I learn a lot this way. If the interesting discussion starts happening someplace else, I won't learn as much, which I would consider a shame. Laura

"A Prolog Interpreter in Python" -- bachelor thesis submitted
by Carl Friedrich Bolz April 18, 2007

April 18, 2007

Hi all! Yesterday I (finally) submitted my bachelor thesis about the implementation of a Prolog interpreter in Python. If you are interested in looking at it, you can find it here: http://codespeak.net/pypy/extradoc/paper/prolog-in-python.pdf Cheers, Carl Friedrich

translator.js.test invokes pygame (AKA, yet more annoyances from Scott)
by Scott Dial April 17, 2007

April 17, 2007

Greetings, There is a bug somewhere in the translator.js.test suite that invokes pygame. I haven't tracked it down but I just thought I'd mention it because I'm sure someone else will know better than me. -Scott -- Scott Dial scott(a)scottdial.com scodial(a)cs.indiana.edu

Socket module on windows
by Amaury Forgeot d'Arc April 15, 2007

April 15, 2007

Hello, I finally managed to port the socket module to windows. It is probably incomplete, but at least it translates, and I prove it: > pypy.exe debug: WARNING: library path not found, using compiled-in sys.path Python 2.4.1 (pypy 1.0.0 build 41908) on win32 Type "help", "copyright", "credits" or "license" for more information. >>>> import socket >>>> s = socket.socket() >>>> s.connect(('localhost', 80)) >>>> s.send('GET\n\n') 5 >>>> s.recv(100) '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"\r\n "http://www.w3.org/TR/xhtml1/DTD' >>>> I can send a (rough) patch file to anybody who wants to test it... Since my svn account is still active, I will carefully submit my changes step by step, hoping not to break anything: I do not have access to a Unix machine, so I will closely follow the results of the nightly tests. Of course your comments are most welcome... there were some rough parts and I am sure I took the wrong way sometimes. Cheers, -- Amaury Forgeot d'Arc

SoC Acceptance!
by Paul deGrandis April 13, 2007

April 13, 2007

Hello everyone! I'm on board for Google Summer of Code (and long after). To refresh everyone's memory I'll be pushing the JVM backend forward and creating JSR-223 bindings to allow you to script PyPy in Java applications. Niko polished off dictionaries, leaving weakrefs to be worked on. Antonio is my mentor, whom I'm very happy and honored to work under. I'm really excited to take this portion of PyPy on. I'll be using my work on the project to advance an autonomic computing project I'm working on and collecting empirical data on PyPy's affect on productivity in a research environment. Results from all my work will be published in research papers. I'll be on IRC and AIM all day tomorrow. Regards, Paul
