Re: [Haskell-cafe] matching

Oops, not quite. "otherwise ==" should be "otherwise =". Looks like you already go this from the first one, but guard syntax looks like: defn | cond1 = ... | cond2 = ... | ... | otherwise = ... (otherwise is not actually necessary; it is just a synonym for True) Luke On Dec 6, 2007 7:09 AM, Luke Palmer wrote:

Just remove that if. What comes after | is already a conditional.

hi

I have a matching problem... I am wanting to identify whether or not a string is an opening substring of another (ignoring leading spaces). I have this: word is a single word and str is a string.

match :: String -> String -> (Bool, String) match word str | if removeSpace str `elem` (removeSpace word) ++ rest = (True, rest) | otherwise == (False,str) where rest = str

Any help?

Ryan
