appendFile :: FilePath -> String -> IO ()
base Prelude, base System.IO
The computation appendFile file str function appends the string str, to the file file. Note that writeFile and appendFile write a literal string to a file. To write a value of any printable type, as with print, use the show function to convert the value to a string first. > main = appendFile "squares" (show [(x,x*x) | x <- [0,0.1..2]])
appendFile :: FilePath -> Text -> IO ()
text Data.Text.IO, text Data.Text.Lazy.IO
