Hi,
Simple question: I need a function that matches string in another string. Something like:
find (isSuffixOf "needle") (inits "haystack")
This one is beautiful, but not very practical. Could anybody point me to some haskell library that does some searching, using KMP for example?
[[ import List foo = isPrefixOf (reverse "needle") (reverse "haystack with needle") bar = isPrefixOf (reverse "needle") (reverse "haystack with pins") ]] Seems to work. And (by inspection) is linear in size of haystack. #g ------------ Graham Klyne For email: http://www.ninebynine.org/#Contact
