[Haskell-cafe] Re: [Haskell] Image manipulation

to find out. There are obvious things like being able to define compositions of transformations -- which is easy to do when you're calling library functions in-memory, and less so if you're using a separate executable -- but maybe there are more interesting applications too. Cheers, Tim -- Tim

Re: [Haskell-cafe] Re: [Haskell] Image manipulation

the experiment before I could give an answer to that. But yeah, if I were the OP, I would probably start by trying to write a shell script (or a simple Haskell program with calls to system) to do what I wanted, and see if that was adequate. Cheers, Tim -- Tim Chevalier * catamorphism.org * Often

Re: [Haskell-cafe] OS Abstraction module??

. Although there's also the System.Info.os function if you want to avoid CPP: http://www.haskell.org/ghc/docs/latest/html/libraries/base/System-Info.html However, since it just returns a string, it may not be too much better than using CPP... Cheers, Tim -- Tim Chevalier * catamorphism.org * Often
