type InputStream = ByteString
readInputStream :: FilePath -> IO InputStream
read a file into an InputStream
inputStreamToString :: InputStream -> String
convert InputStream
to String
inputStreamFromString :: String -> InputStream
convert a String
to an InputStream
takeChar :: InputStream -> (Char, InputStream)
(c,is') = takeChar is
reads and removes
the first character c
from the InputStream
is
inputStreamEmpty :: InputStream -> Bool
return True
if the given input stream is empty
takeChars :: Int -> InputStream -> [Char]
str = takeChars n is
returns the first n
characters
of the given input stream, without removing them
countLines :: InputStream -> Int
countLines
returns the number of text lines in the
given InputStream
