[Haskell] implementing pointers-based data structure

ively-defined data type (like standard haskell list) ? is-it possible ? or would it be good to define the data structure in c and write a haskell wrapper around the c code ? thank you a lot, bye, vo minh thu ___ Haskell mailing list Haskell@haskell.org

[Haskell] reading binary files

line for the reading/reconstructing more-than-one-Word8 value. is it already possible ? would it be interesting to add such capabilities to haskell ? (i think so) i can try to add it but i need some pointers about how to do it. thx a lot, vo minh thu ___

Re: [Haskell] reading binary files

plumbing (maybe another buffer) to read file. so maybe that in all cases, we're losing efficiency when reading a file ? also, if our buffer allocation is mandatory, the compiler could put the right code for us (i.e. choose the best buffer length). again thx, minh thu 2006/4/6, Bulat Zigansh

Re: Re[2]: [Haskell] reading binary files

thanks a lot Bulat ! i ve seen the lib use System.Stream which i don't know... the fact you can discribe a layout then read a file according to the layout is just a feature i thought about. i'll definitely learn your library. minh thu 2006/4/6, Bulat Ziganshin <[EMAIL PROTECTED]&g

Re: [Haskell] Lazy IO breaks purity

Hi, It seems to me that basically, a run of Oleg's code is :: IO Int, not Int, so there is little sense to talk about referential transparencies by comparing the results of two runs. It would have sense by making the comparison directly in a single run, inside the code (using a pure compare funct

It seems like the infered type (and thus bounds) is different when you force the result to be a Color or not. Just give explicit type signatures and conversion functions. Cheers, Thu 2012/7/16 Andreas Abel : > Today a student came to me with a piece of code that worked it executed by > itself, bu
