Language.C.Data.InputStream
Description
Compile time input abstraction for the parser, relying on ByteString. The String interface only supports Latin-1 since alex-3, as alex now requires byte based access to the input stream.
Synopsis
- type InputStream = ByteString
- readInputStream :: FilePath -> IO InputStream
- inputStreamToString :: InputStream -> String
- inputStreamFromString :: String -> InputStream
- takeByte :: InputStream -> (Word8, InputStream)
- takeChar :: InputStream -> (Char, InputStream)
- inputStreamEmpty :: InputStream -> Bool
- takeChars :: Int -> InputStream -> [Char]
- countLines :: InputStream -> Int
Documentation
type InputStream = ByteString Source #
readInputStream :: FilePath -> IO InputStream Source #
read a file into an InputStream
inputStreamToString :: InputStream -> String Source #
convert InputStream to String
inputStreamFromString :: String -> InputStream Source #
convert a String to an InputStream
takeByte :: InputStream -> (Word8, InputStream) Source #
(b,is') = takeByte is reads and removes
the first byte b from the InputStream is
takeChar :: InputStream -> (Char, InputStream) Source #
(c,is') = takeChar is reads and removes
the first character c from the InputStream is
inputStreamEmpty :: InputStream -> Bool Source #
return True if the given input stream is empty
takeChars :: Int -> InputStream -> [Char] Source #
str = takeChars n is returns the first n characters
of the given input stream, without removing them
countLines :: InputStream -> Int Source #
countLines returns the number of text lines in the
given InputStream
