Monky.Utility

This module provides utility functions used in monky modules

Documentation

readValue :: File -> IO Int

Read the first line of the file and convert it into an Int

readValueI :: File -> IO Integer

Read the first line of the file and convert it into an Integer

readValues :: File -> IO [Int]

Read the first line of the file and convert the words in it into Ints

fopen :: String -> IO File

open a file read only

fclose :: File -> IO ()

Close a file opened by fopen

data File

type alias to distinguish system functions from utility

Instances

Eq File

Methods

(==) :: File -> File -> Bool

(/=) :: File -> File -> Bool

Show File

Methods

showsPrec :: Int -> File -> ShowS

show :: File -> String

showList :: [File] -> ShowS

readLine :: LineReadable a => File -> IO a

Read the first line of the file

readContent :: FileReadable a => File -> IO [a]

Rewind the file descriptor and read the complete file as lines

findLine :: Eq a => [a] -> [[a]] -> Maybe [a]

Find a line in a list of Strings

splitAtEvery :: String -> String -> [String]

Split ys at every occurence of xs

maybeOpenFile :: Maybe String -> IO (Maybe File)

fmap fopen would give Maybe (IO File), this fixes that

sdivBound :: (Integral a, Bounded a) => a -> a -> a infixl 7

0 save divide, uses maxbound for default value

sdivUBound :: Integral a => a -> a -> a -> a infixl 7

0 save divide, uses default value

listDirectory :: FilePath -> IO [FilePath]

listDirectory dir returns a list of all entries in dir without the special entries (. and ..).

The operation may fail with:

• HardwareFault A physical I/O error has occurred. [EIO]
• InvalidArgument The operand is not a valid directory name. [ENAMETOOLONG, ELOOP]
• isDoesNotExistError / NoSuchThing The directory does not exist. [ENOENT, ENOTDIR]
• isPermissionError / PermissionDenied The process has insufficient privileges to perform the operation. [EACCES]
• ResourceExhausted Insufficient resources are available to perform the operation. [EMFILE, ENFILE]
• InappropriateType The path refers to an existing non-directory object. [ENOTDIR]

Since: 1.2.5.0
