Synopsis

getRawInput :: Int -> Int -> IO String
inputFileName :: Int -> FilePath
getInputLines :: Int -> Int -> IO [String]
getInputArray :: Int -> Int -> IO (UArray Coord Char)
getInputMap :: Int -> Int -> IO (Map Coord Char)

Documentation

getRawInput Source #

Arguments

:: Int	year
-> Int	day number
-> IO String

Get the input for the given day.

If a filename is provided in the command line that will be used as the input file.

If the filename is - the stdin will be used as the input file.

Otherwise the input text file corresponding to the day number will be used.

inputFileName Source #

Arguments

:: Int	day
-> FilePath

Default input filename given a day number

getInputLines Source #

Arguments

:: Int	year
-> Int	day
-> IO [String]

Load input file as a list of lines.

getInputArray Source #

Arguments

:: Int	year
-> Int	day
-> IO (UArray Coord Char)

Load input file as a rectangular array of characters.

getInputMap Source #

Arguments

:: Int	year
-> Int	day
-> IO (Map Coord Char)

Load input file as a 2-dimensional map of characters.
