Documentation

encodeEOF :: Binary a => FilePath -> a -> IO ()

Serialize, compress and save data with an EOF marker. The OK is used as an EOF marker to ensure any apparent problems with corrupted files are reported to the user ASAP.

strictDecodeEOF :: Binary a => FilePath -> IO a

Read, decompress and deserialize data with an EOF marker. The OK EOF marker ensures any easily detectable file corruption is discovered and reported before the function returns.

tryCreateDir :: FilePath -> IO ()

Try to create a directory, if it doesn't exist. Terminate the program with an exception if the directory does not exist, but can't be created.

tryCopyDataFiles :: FilePath -> (FilePath -> IO FilePath) -> [(FilePath, FilePath)] -> IO ()

Try to copy over data files, if not already there.

appDataDir :: IO FilePath

Personal data directory for the game. Depends on the OS and the game, e.g., for LambdaHack under Linux it's ~/.LambdaHack/.
