Description

Provides the MonadFileWriter effect.

Since: 0.1

Synopsis

Effect

class Monad m => MonadFileWriter (m :: Type -> Type) where Source #

Represents file-system writer effects.

Since: 0.1

Methods

writeBinaryFile :: OsPath -> ByteString -> m () Source #

Writes to a file.

Since: 0.1

appendBinaryFile :: OsPath -> ByteString -> m () Source #

Methods

writeBinaryFile :: OsPath -> ByteString -> IO () Source #

appendBinaryFile :: OsPath -> ByteString -> IO () Source #

MonadFileWriter m => MonadFileWriter (ReaderT env m) Source #

Since: 0.1

Instance details

Defined in Effects.FileSystem.FileWriter

Methods

writeBinaryFile :: OsPath -> ByteString -> ReaderT env m () Source #

appendBinaryFile :: OsPath -> ByteString -> ReaderT env m () Source #

type OsPath = OsString #

Type representing filenames/pathnames.

This type doesn't add any guarantees over OsString.

UTF-8 Utils

writeFileUtf8 :: (HasCallStack, MonadFileWriter m) => OsPath -> Text -> m () Source #

Writes to a file as UTF-8.

Since: 0.1

appendFileUtf8 :: (HasCallStack, MonadFileWriter m) => OsPath -> Text -> m () Source #

Appends to a file as UTF-8.

Since: 0.1

encodeUtf8 :: Text -> ByteString #

Encode text using UTF-8 encoding.

Reexports

data ByteString #

A space-efficient representation of a Word8 vector, supporting many efficient operations.

A ByteString contains 8-bit bytes, or by using the operations from Data.ByteString.Char8 it can be interpreted as containing 8-bit characters.

IsString ByteString

Beware: fromString truncates multi-byte characters to octets. e.g. "枯朶に烏のとまりけり秋の暮" becomes �6k�nh~�Q��n�
