[Haskell] Read and write file on Windows XP.

I have a small program which simply reads a text file, gets the second line and changes it and writes a clone file with the second line changed. Basically it looks like that: main :: IO() main =do -- Some code here hexFile - catch (readFile int.hex) (\_ - do putStrLn File

Re: [Haskell-cafe] Using catch and errors

Thanks for the tips. (There's also the obvious syntax error of not quoting the string int.hex, but I suspect you would have caught that one.) In fact it was supposed to be there. Just a typo I guess After the catch, you have another instance of the readFile command you would have just run,

Re: [Haskell-cafe] a newbie's question

Well I think one of the best tools to programme on for Windows is UltraEdit, it will give you colors and other stuff (provided you get the correct file for it which is out on the net). Emacs also exists for windows and is not bad, but I don't know if that is the best tool (I sure like it but I

Help with Exceptions on I/O

I have a program which creates textfiles out of other files. Since theprogram is runned from windows I output some text strings (Like "Filecreated succefully") and I need to stop the program before it quits so thatthe user can read the line outputted to know what went on and then he canpress

How to search for a string sequence in a file a rewrite it???

OK Guys. First I would like to say thanks for all the help given before. As I said I am still learning Haskell. My problem is the following: I have a text file and somewhere in the file there is string (Let's say ). So I need to find this exact string and overwrite with another string (Lets

Thanks a lot m8 but ghc says it can't the module IOExts when I try to compile, any suggestion??? Do I just use normal writeFile method to create the text file then?? Best Regards Alex - Original Message - From: Glynn Clements [EMAIL PROTECTED] To: Alexandre Weffort Thenorio [EMAIL

How to force UNIX text files as output instead of DOS text files??

I am working on a small program which writes a text file but I need this file to be in UNIX format and as it is a Windows program I am compiling it, the output file tends to be in DSO format. Is there anyway that I can force it to create the file in UNIX format??? Best Regards NooK
