Monky.Utility

Description

This module provides utility functions used in monky modules

Synopsis

Documentation

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

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

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

open a file read only

Close a file opened by fopen

type alias to distinguish system functions from utility

Instances

Eq File Source #
Methods (==) :: File -> File -> Bool # (/=) :: File -> File -> Bool #
Show File Source #
Methods showsPrec :: Int -> File -> ShowS # show :: File -> String # showList :: [File] -> ShowS #

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

Read the first line of the file

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

Rewind the file descriptor and read the complete file as lines

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

Find a line in a list of Strings

Split ys at every occurence of xs

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

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

0 save divide, uses maxbound for default value

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

0 save divide, uses default value

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

The haskell type for Cs utsname (man uname)

Instances

Eq UName Source #
Methods (==) :: UName -> UName -> Bool # (/=) :: UName -> UName -> Bool #
Show UName Source #
Methods showsPrec :: Int -> UName -> ShowS # show :: UName -> String # showList :: [UName] -> ShowS #
Storable UName Source #
Methods sizeOf :: UName -> Int # alignment :: UName -> Int # peekElemOff :: Ptr UName -> Int -> IO UName # pokeElemOff :: Ptr UName -> Int -> UName -> IO () # peekByteOff :: Ptr b -> Int -> IO UName # pokeByteOff :: Ptr b -> Int -> UName -> IO () # peek :: Ptr UName -> IO UName # poke :: Ptr UName -> UName -> IO () #
