   OpenGL	Graphics.Rendering.OpenGL.GL.ReadCopyPixels

   No documentation available.

2. readPixels :: Position -> Size -> PixelData a -> IO ()

   OpenGL	Graphics.Rendering.OpenGL.GL.ReadCopyPixels

   No documentation available.

3. readBitmapFile :: Display -> Drawable -> String -> IO (Either String (Dimension, Dimension, Pixmap, Maybe CInt, Maybe CInt))

   X11	Graphics.X11.Xlib.Misc

   interface to the X11 library function XReadBitmapFile.

4. readDouble :: String -> Maybe Double

   basement	Basement.String

   Try to read a Double

5. readFloatingExact :: String -> ReadFloatingCallback a -> Maybe a

   basement	Basement.String

   Read an Floating like number of the form:

   • - numbers [ . numbers ] [ ( e | E ) [ - ] number ]
   Call a function with:
   • A boolean representing if the number is negative
   • The digits part represented as a single natural number (123.456 is represented as 123456)
   • The number of digits in the fractional part (e.g. 123.456 => 3)
   • The exponent if any
   The code is structured as a simple state machine that:
   • Optionally Consume a - sign
   • Consume number for the integral part
   • Optionally
   • Consume .
   • Consume remaining digits if not already end of string
   • Optionally Consume a e or E follow by an optional - and a number

6. readInteger :: String -> Maybe Integer

   basement	Basement.String

   No documentation available.

7. readIntegral :: (HasNegation i, IntegralUpsize Word8 i, Additive i, Multiplicative i, IsIntegral i) => String -> Maybe i

   basement	Basement.String

   Read an Integer from a String Consume an optional minus sign and many digits until end of string.

8. readNatural :: String -> Maybe Natural

   basement	Basement.String

   Read a Natural from a String Consume many digits until end of string.

9. readRational :: String -> Maybe Rational

   basement	Basement.String

   Try to read a floating number as a Rational Note that for safety reason, only exponent between -10000 and 10000 is allowed as otherwise DoS/OOM is very likely. if you don't want this behavior, switching to a scientific type (not provided yet) that represent the exponent separately is the advised solution.

10. readFile :: FilePath -> IO Bytes

    byteslice	Data.Bytes

    Read an entire file strictly into a Bytes.
