Documentation

isDir

Arguments

:: Word32

Permissions

-> Bool

Tests if the file is a directory

simpleFile

Arguments

:: (Monad m, EmbedIO m, ReadRef rr m a, Convertible a ByteString, WriteRef wr m b, Convertible ByteString b)

=> String

File name

-> rr

Reading function

-> wr

Writing function

-> NineFile m

A file that reads from and writes to the supplied Ref instances, with converstion to the appropriate types. See Instances, Instances and Instances. Use '()', if the file is meant to be read-only/write-only.

simpleFileBy

Arguments

:: (Monad m, EmbedIO m)

=> String

File name

-> (m a, b -> m ())

Reading and writing handle

-> (a -> ByteString, ByteString -> b)

Type conversion handles

-> NineFile m

Typeclass-free version of simpleFile.

simpleDirectory

Arguments

:: (Monad m, EmbedIO m)

=> String

File name

-> (String -> m (NineFile m))

A function for creating new files

-> (String -> m (NineFile m))

A function for creating new directories

-> IO (NineFile m, IORef [(String, NineFile m)])

A directory that stores its contents in the form of 'IORef [(String, NineFile m)]'

rwFile

Arguments

:: EmbedIO m

=> String

File name

-> Maybe (m ByteString)

Read handler

-> Maybe (ByteString -> m ())

Write handler

-> NineFile m

A file that reads and writes using simple user-specified callbacks.

memoryFile

Arguments

:: (Monad m, EmbedIO m)

=> String

File name

-> IO (NineFile m)

A file that stores its contents in the form of IORef ByteString

memoryDirectory

Arguments

:: (Monad m, EmbedIO m)

=> String

File name

-> IO (NineFile m)

A composition of a simpleDirectory and a memoryFile
