String construction

toPlatformString :: String -> PosixString

Total Unicode-friendly encoding.

On windows this encodes as UTF16, which is expected. On unix this encodes as UTF8, which is a good guess.

toPlatformStringIO :: String -> IO PosixString

Like toPlatformString, except on unix this uses the current locale for encoding instead of always UTF8.

Looking up the locale requires IO. If you're not worried about calls to setFileSystemEncoding, then unsafePerformIO may be feasible.

bsToPlatformString :: MonadThrow m => ByteString -> m PosixString

Constructs an platform string from a ByteString.

On windows, this ensures valid UTF16, on unix it is passed unchanged/unchecked.

Throws UnicodeException on invalid UTF16 on windows.

pstr :: QuasiQuoter

QuasiQuote a PosixString. This accepts Unicode characters and encodes as UTF-8 on unix.

packPlatformString :: [PosixChar] -> PosixString

String deconstruction

fromPlatformString :: MonadThrow m => PosixString -> m String

Partial unicode friendly decoding.

On windows this decodes as UTF16 (which is the expected filename encoding). On unix this decodes as UTF8 (which is a good guess). Note that filenames on unix are encoding agnostic char arrays.

Throws a UnicodeException if decoding fails.

fromPlatformStringEnc :: PosixString -> TextEncoding -> Either UnicodeException String

Like fromPlatformString, except on unix this uses the provided TextEncoding for decoding.

fromPlatformStringIO :: PosixString -> IO String

Like fromPlatformString, except on unix this uses the current locale for decoding instead of always UTF8.

Looking up the locale requires IO. If you're not worried about calls to setFileSystemEncoding, then unsafePerformIO may be feasible.

Throws UnicodeException if decoding fails.

unpackPlatformString :: PosixString -> [PosixChar]

Word construction

unsafeFromChar :: Char -> PosixChar

Truncates to 1 octet.

Word deconstruction

toChar :: PosixChar -> Char

Converts back to a unicode codepoint (total).
