Hi, I just start learning haskell and have to say that it is stunning in how precise it can be(coming from a background of C then python/perl/js). I want to write apps for WEB and have briefly read WASH. However, that seems to be a CGI based solution. What I want is a native HTTP server(written in haskell), like Twisted/Cherrypy in Python. Are there any boilerplate(I know I should scrap the boilerplate but I need to have something to get start) for reference ? In addition, during my learning process, I keep on using my old experience as reference such as writing simple programs that needs functions like ltrim/rtrim/substr etc. that is in almost any language I have used. But it seems that haskell doesn't have it. I know that a haskell expert can write them in no time with things like dropWhile and reverse, it is a bit frustrating for new comers from a imperative background. Oh, while I am still here, I am reading "The Evolution of a Haskell Programmer" http://www.willamette.edu/~fruehr/haskell/evolution.html and learning the various way to tackle the same problem. Obviously, there are lots of things I don't know what it is about and I would tackle them as time go by. But I have problem even with the seems to be simple one like this : fac n = foldr (\x g n -> g (x*n)) id [1..n] 1 I can understand a foldl or foldr version but have problem with this, especially the "id" and the trailing "1" and the function being folded takes 3 parameters instead of 2(as in standard foldr/foldl solution). Would appreciate if someone can knock on my head and tell me what is going on in it. thanks for help in advance. regards, gary ______________________________________________________ Click here to donate to the Hurricane Katrina relief effort. http://store.yahoo.com/redcross-donate3/
