getIncludePath :: String -> IO String   

Returns the path of a file provided as an argument in the include directory of the package or, if this does not exists, in the local include directory. If both does not exist, a warning is issued.

showQNameNoDots :: (String,String) -> String   

showWithLineNums :: String -> String   

Shows a text with line numbers preceded:

ilog :: Int -> Int   

The value of ilog n is the floor of the logarithm in the base 10 of n. Fails if n <= 0. For positive integers, the returned value is 1 less the number of digits in the decimal representation of n.

Example call:

(ilog n)

Parameters:

• n : The argument.

Returns:

the floor of the logarithm in the base 10 of n.

Further infos:

• partially defined
