[Haskell-cafe] Finally, a pure iteratee library that deals with errors

2012-02-26 Thread Daniel Waterworth
Hi all, There's seems to be a growing trend amongst the Haskell community for writing replacements of enumerator. It's shortcomings are well documented, but the solution is, IMO, undecided. This is my attempt: https://gist.github.com/1915841 I have largely copied pipes' concept. The major

Nice, thank you. I was wondering recently what was the current state of Gabriel's pipes and Paolo's guarded variant. IIRC, they were working on a converging branch with good support at resources early termination. On Sun, 26 Feb 2012 10:50:22 +, Daniel Waterworth da.waterwo...@gmail.com

I didn't really look into (enumerators/iteratees/conduits/etc)-land closely enough, but I can say one thing. The code you link to is very easy to understand and see what is going on. This must be a good thing. On 26 February 2012 10:50, Daniel Waterworth da.waterwo...@gmail.comwrote: There's

[Haskell-cafe] FFI: Overhead of foreign unsafe imports

2012-02-26 Thread Yves Parès
Hello, When I was using C code from Python, the overhead put on calling C code by Python was significant. To simplify, say I have on C-side two procedures f and g, I do all the stuff to call them in a row from Python, well I'm better off factorizing: adding on C side a wrapper h procedure that

Hi, I didn't thought it would be a full rewrite, when I finish Jpeg writing functionality, I will look at it in depth, which will not be immediately. Feel free to use any code snippet from JuicyPixels if it help your for your own library. Regards Vincent Berthoux Le 24 février 2012

Here's the same code but with a variation on Multiplate that doesn't use records, but a GADT: https://gist.github.com/1919528 It is easier on the eyes I think, but probably not any easier to decipher. But hey, this is generic programming for mutually recursive datatypes, that's a complicated

Thanks everyone! This has been interesting and helpful. I for one had not seen multirec, but will check it out. Is the implication that multirec is more or less complicated than multiplate? Cheers, -matt On Sun, Feb 26, 2012 at 3:28 PM, Sjoerd Visscher sjo...@w3future.com wrote: Here's the
