Hi all, I am having problems adding multiple definitions with where for example in my code --A parser for recognising binary operations parseBinaryOp :: String -> String -> [(Expr, Expr, String)] parseBinaryOp op str | (elem op binops) && (notElem '(' (snd bm)) && (notElem ')' (snd bm)) && (elem nstr!!1 binops) = [(EInt 1, EInt 1, "HERE!")] | otherwise = [] where bm = bracketMatch str nstr = words (snd (bracketMatch str)) I get the error message parse error on input `=' Essentially this function is supposed to parse binary operations in a string, nstr is just a [String], binops is a list of Strings. The types appear to be fine, and GHCI dosnt say that this is the problem, the problem seems to lie with that definition of nstr after the definition of bm. I believe I have followed the definitions correctly, so I am at a loss for how to solve this problem. The list that is given for the first case is only a placeholder, once I get past this problem I should be able to make the function operate properly Any help would be much appreciated, please tell me if you need more info.
