The correct solution however, is the application of 'seq' at the right places. To understand where these are, perform a simulation of Haskell's reduction strategy on paper.
I will definitely try that.
30 Mega used for reading a feed is a number that I seem to get.
Depends on what you're doing with the data. If you scan a stream of Chars exactly once, the space requirement per Char is next to irrelevant. If you're keeping lots of Strings around, using PackedStrings will help (and be sure to pack strictly). But I actually suspect, you are running a backtracking parser over your input, so the whole input is read into a String and cannot be disposed of as long as the parser might backtrack. If this is Parsec, you need to remove a redundant 'try'. If it is the Read class, you need to replace it by Parsec or ReadP...
No. I'm actually using the ReadDocument module of HXT for reading my input and writeDocument for writing. So, it's parsec, on your side...;-) The application I'm writing is basically a HXT application, with an hscurser gui. If you have some hints on how to make memory consumption go down that would be great. Thanks for your kind attention. Andrea
