Description

Higher-level file patterns. Don't support read/write operations at offsets and handling stat changes as for now.

Synopsis

Documentation

isDir Source #

Arguments

:: Word32	Permissions
-> Bool

Tests if the file is a directory

simpleFile Source #

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 Source #

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 Source #

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 Source #

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 Source #

Arguments

:: (Monad m, EmbedIO m)
=> String	File name
-> IO (NineFile m)

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

memoryDirectory Source #

Arguments

:: (Monad m, EmbedIO m)
=> String	File name
-> IO (NineFile m)

A composition of a simpleDirectory and a memoryFile
