I am trying to read a string from keyboard. This is my code so far:
getLine :: IO String
getLine = do x <- getChar if x=='\n' then return [] else do xs<-getLine return (x:xs)
The problem is that I get this error when compiling:
parse error on input 'if'
Any ideas what I am doing wrong?
If you're going to insist on writing everything on one line, you'll need to insert a semicolon between consecutive statements in do blocks:
getLine = do x <- getChar; if x=='\n' then return [] else do xs<-getLine; return (x:xs)
^ here ^ and here
It would be better to just split the whole thing across multiple lines, though:
getLine = do x <- getChar
if x=='\n' then return []
else do xs<-getLine
return (x:xs)
