Re: [Edu-sig] Visual Programming in Python?

This just showed up on edu-sig. Is the translator and viewer separate enough that we could just send it to this person? Laura In a message of Thu, 13 Apr 2006 12:56:12 EDT, "Douglas S.

Information from the FlowObjSpace
by Brian C. Lum April 13, 2006

April 13, 2006

Dear Pypy developers: I have gone through the source code for the FlowObjSpace in pypy.objspace.flow.objspace, but I am confused how to traverse through the blocks or obtain the information for each blocks in the graph. From my understanding: space = FlowObjSpace() graph = space.build_flow(func) Once you have the graph, however, how do you know what instructions are in each block? I can iterate through the graph with iterblocks, but how do I get information from each block? I want to … [View More]

A problem with unbound methods
by Antonio Cuni April 12, 2006

April 12, 2006

Hi, I have some problems for translating calls to unbound methods. Let's show with an example: class MyClass: def __init__(self, x): self.x = x class MyDerivedClass(MyClass): def __init__(self, x): MyClass.__init__(self, x) During rtyping the field and method names are mangled, so the __init__ method became something like 'o__init____variant0': as long as I call bound methods this is not a problem because the low-level op oosend contains the right mangled name, … [View More]

pypy embedded / new atmel 32
by Michael Schneider April 12, 2006

April 12, 2006

Hello All, I have been very interested in pypy and embedded systems. I use atmel's line (cheap, easy architecture, gcc). It is still a bit cramped for pypy. Atmel just introduced their 32 bit line. It is a whopping $16 per unit. Paralles Propeller chip uses sping (some python linage). Would the new AVR be a candidate for pypy?

Printing a Flowgraph
by Brian C. Lum April 11, 2006

April 11, 2006

Dear Pypy developers: I was reading how you generate a flowgraph with Pypy from the getting-started page. I was just wondering if anyone knew how to print that graph once it displays. I don't really have much experience with Graphviz. Is there a way to save the graphviz file or print it to a .ps? http://codespeak.net/pypy/dist/pypy/doc/getting-started.html#trying-out-the… Thanks! Brian Just an FYI, if you want to try to follow the directions, they're a little bit outdated. To run it … [View More]

std objectspace interface
by Stephan Diehl April 7, 2006

April 7, 2006

Hallo all, I have a question about the standard objectspace interface. It's about how to best return an iterator. While writing the 'set' implementation, it occured to me, that I'm using a W_SeqIterObject directly, which is bad, since this breaks the intended separation of types / objects. Instead, I'd like to use something like space.newseqiter. But 'newseqiter' takes a wrapped object, while I'd rather use a way to 'translate' some interp level iterator of wrapped objects directly to an … [View More]

Re: [pypy-dev] List and string in ootypesystem
by Niklaus Haldimann April 6, 2006

April 6, 2006

Hi Antonio (and others) As you have probably seen, we started work on list support for ootypesystem here at the ongoing Leysin sprint. This cleared things up a bit for me on the conceptual level. Here's how OO lists work: - There is a new type constructor "List" in the ootype module. The low-level type of RPython list in the ootypesystem is a List instance with the item type of the list provided as an argument. E.g., an RPython list of integers has the low-level type List(Signed). - The … [View More]
