pypy2exe
by Paolo Basso March 21, 2012

March 21, 2012

Perhaps this will sound like a newbie question but IMHO a lot of people would benefit of some clarification and more info.... Here's the point: what if I want to build an executable using pypy (possibly with a GUI)? I'm not a pro of course, but with cpython I'm able to do it quite easily thanks to py2exe and many GUI frameworks (Qt also comes with a designer). Is there or will be there something like a pypy2exe or already exists a step by step guide I missed? May be rpythonic (http://code.… [View More]

targetreallynopstandalone.py => TypeError: string vs LocalPath
by Peter Cock March 21, 2012

March 21, 2012

Hi all, After a teething error with PyPy calling GCC with unescaped paths, which I solved by moving to a directory without spaces in the full path, I made some progress. First, get PyPy from hg - perhaps checking out a known good revision: $ hg clone http://bitbucket.org/pypy/pypy pypy $ cd pypy $ hg checkout release-1.8 Next, using the Richards example (short but non-trivial), $ cd pypy/translator/goal $ python translate.py --run targetrichards.py ...

The same happens with the default branch, 53817:62902925695c What's going wrong? Am I invoking translate.py incorrectly? Thanks, Peter [View Less]

Does anyone have a git-mapfile?
by Michael Blume March 20, 2012

March 20, 2012

I know there's a github mirror at github.com/pypy/pypy, but in order to shuffle commits between the two repos, I need to either perform the translation myself (and I let an EC2 instance run on that for 9 hours...) or get a git-mapfile with a list of corresponding commits. If you have a bi-directional repository, it'd be found at pypy/.hg/git-mapfile. Thanks! -Mike

how embed pypy into c?
by Simon Liu March 20, 2012

March 20, 2012

Hi all. I want to embed pypy into c code, but in pypy's directory, i don't find any pypy's c api, except in cypext directory. And I want to use stackless' c api too,. but i still have not found any stackless api(example stackless_api.h) in pypy. Thanks. -- do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric.

Finite automata
by Alexander Sedov March 20, 2012

March 20, 2012

Hello PyPy community, Looks like I have a patch that somehow simplifies automatas generated by pypy.interpreter.pyparser.{pylexer,genpytokenize}. It's rather obvious patch that enables: * Comparing labels in right order; * Checking for loops; * Checking for mutual links. It is mathematically correct, although it does NOT produce minimal automata in some cases. It reduces number of resulting states, though. I'm having troubles with pytest (no such option: --assertmode) so I could not test it. If … [View More]

Speeding up zlib in standard library
by Peter Cock March 15, 2012

March 15, 2012

Hi all, I am looking at some benchmark numbers from some of my code, and one area where PyPy is slower than 'C' Python (perhaps twice as slow) is code making heavy use of the zlib standard library. I had a look at this page about how C libraries are called from PyPy, it seems sketchy and perhaps somewhat out of date too. I'd find it helpful if it commented on what PyPy was using for the standard library C modules: http://doc.pypy.org/en/latest/extending.html Looking at the source of the … [View More]

Call for Papers: Dynamic Languages Symposium 2012
by Carl Friedrich Bolz March 15, 2012

March 15, 2012

Dynamic Languages Symposium 2012 October 22, 2012 Co-located with SPLASH 2012 In association with ACM SIGPLAN Tucson, Arizona, USA http://www.dynamic-languages-symposium.org/dls-12/ **** Call for Papers **** The 8th Dynamic Languages Symposium (DLS) at SPLASH 2012 is a forum for the discussion of dynamic languages, their implementation and application. While mature dynamic languages including Smalltalk, Lisp, Scheme, Self, Prolog, and APL continue to grow and inspire new converts, a … [View More]new generation of dynamic scripting languages such as JavaScript, Python, Ruby, PHP, Tcl, Lua, and Clojure are successful in a wide range of applications. DLS provides a place for researchers and practitioners to come together and share their knowledge, experience, and ideas for future research and development. DLS 2012 invites high quality papers reporting original research, innovative contributions or experience related to dynamic languages, their implementation and application. Accepted Papers will be published in the ACM Digital Library. Areas of interest include but are not limited to: * Innovative language features and implementation techniques * Development and platform support, tools * Interesting applications * Domain-oriented programming * Very late binding, dynamic composition, and runtime adaptation * Reflection and meta-programming * Software evolution * Language symbiosis and multi-paradigm languages * Dynamic optimization * Hardware support * Experience reports and case studies * Educational approaches and perspectives * Object-oriented, aspect-oriented, and context-oriented programming === Submissions and proceedings === We invite original contributions that neither have been published previously nor are under review by other refereed events or publications. Research papers should describe work that advances the current state of the art. Experience papers should be of broad interest and should describe insights gained from substantive practical applications. The program committee will evaluate each contributed paper based on its relevance, significance, clarity, length, and originality. Papers should be of a length appropriate to their content: a shorter paper may be sufficient to describe a smaller but still significant result, and no paper will be rated poorly solely based on its length. Accepted papers will be published in the ACM Digital Library. Papers are to be submitted electronically at http://www.easychair.org/conferences?conf=dls12 in PDF format. Submissions should not exceed 12 pages and need to use the ACM format, templates for which can be found at http://www.sigplan.org/authorInformation.htm. === Important dates === Submission of papers: July 11, 2012 (hard deadline) Author notification: August 1, 2012 Final versions due: August 15, 2012 DLS 2012: October 22, 2012 SPLASH 2012: October 19-26, 2012 === Program chair === Alessandro Warth, Google, USA === Program committee === * Henry Baker, USA * Carl Friedrich Bolz, Heinrich-Heine-Universität Düsseldorf, Germany * Gilad Bracha, Google, USA * William R. Cook, University of Texas at Austin, USA * Pascal Costanza, Intel, Belgium * Tom Van Cutsem, Vrije Universiteit Brussel, Belgium * Marcus Denker, Inria, France * Matthew Flatt, University of Utah, USA * Charlotte Herzeel, Vrije Universiteit Brussel, Belgium * Robert Hirschfeld, Hasso-Plattner-Institut Potsdam, Germany * Sam Tobin-Hochstadt, Northeastern University, USA * Mark Miller, Google, USA * Todd Millstein, University of California, Los Angeles, USA * James Noble, Victoria University of Wellington, New Zealand * Laurence Tratt, King's College London, UK * Alessandro Warth, Google, USA (chair) [View Less]
