SIMD powered Python

Hi! Is there any I&D ongoing about using SIMD [1] instructions, like SSE [2], to speed up Python, especially regarding functional features, like list comprehension, map and reduce, etc.. ? Best regards, Hugo Ferreira -- [1] http://en.wikipedia.org/wiki/SIMD [2] http://en.wikipedia.org/wiki/Str

Re: Detecting recursion loops

Hi! I hope you are not trying to find infinite loops and I simply misunderstood your question. Because if you are, then forget it (Turing anyone?)... Infinite loops are impossible to find (minus some few, very specific situations). Cf. http://en.wikipedia.org/wiki/Halting_problem Cheers, Hugo F

libboost, python, and dijkstra shortest path

Hi everyone, I need to implement a very quick (performance-wise) Dijkstra shortest path in python, and found that libboost already has such thing. Problem is: I cannot find the installation package for my Python 2.4 under windows. Can someone please provide me instructions for installing libboost

Heya there, Ok, found the solution. I just needed to use leaveWhiteSpace() in the places I want pyparsing to take into consideration the spaces. Thx for the help. Cheers! Hugo Ferreira On Nov 23, 11:57 am, "Bytter" <[EMAIL PROTECTED]> wrote: > (This message has already been

Re: PyParsing and Headaches

, for example, ANTLR (in fact, I've already put aside ANTLR more than once in the past for a built-from-scratch parser). Cheers, Hugo Ferreira On Nov 22, 7:50 pm, Chris Lambacher <[EMAIL PROTECTED]> wrote: > On Wed, Nov 22, 2006 at 11:17:52AM -0800, Bytter wrote: > > Hi, >

PyParsing and Headaches

Hi, I'm trying to construct a parser, but I'm stuck with some basic stuff... For example, I want to match the following: letter = "A"..."Z" | "a"..."z" literal = letter+ include_bool := "+" | "-" term = [include_bool] literal So I defined this as: literal = Word(alphas) include_bool = Optional(

Rendering Vector Graphics

Hi ppl, I've already posted this message through the mailing-list, but it seems it never arrived here. Strange... Anyway: I need to render high-quality vector graphics with Python. I was thinking of something like 'cairo', though I need to run under win32 and can't find a pycairo package for it.
